Musculoskeletal Disorders

TOPLINE:

Subcutaneous tocilizumab provides durable disease control rates in patients with polyarticular and systemic juvenile idiopathic arthritis (pJIA and sJIA, respectively).

METHODOLOGY:

• This long-term extension (LTE) study included 44 patients with pJIA and 38 patients with sJIA, according to the International League of Associations for Rheumatology criteria, from two 52-week phase 1b trials (NCT01904292 and NCT01904279).
• In the core trials, the dosing frequency of subcutaneous tocilizumab was determined by weight: Every 3 weeks for those < 30 kg in pJIA and every 2 weeks for those ≥ 30 kg; in sJIA, initially every 10 days for those < 30 kg, transitioning to every 2 weeks, and weekly for those ≥ 30 kg.
• Patients who had adequate disease control with subcutaneous tocilizumab, comparable with the use of intravenous tocilizumab in the core trials, continued to receive subcutaneous tocilizumab.
• The study outcome was the change in Juvenile Arthritis Disease Activity Score on 71 joints (JADAS-71, range 0-101).

TAKEAWAY:

• Disease control remained stable in both groups, with sustained improvements in median JADAS-71 scores in pJIA (−0.2 with lower frequency dosing to −0.5 with higher frequency) and sJIA (−0.1 at both dosing frequencies).
• In the pJIA group, 90% and 53% of patients weighing < 30 kg and ≥ 30 kg achieved inactive disease, respectively, whereas in the sJIA group, the respective rates were 91% and 92%.
• A total of five of 15 patients with pJIA weighing ≥ 30 kg who received subcutaneous tocilizumab every 2 weeks achieved clinical remission, whereas in other groups, the clinical remission rates ranged from 74% to 92%.
• Six patients with pJIA reported seven serious adverse events (SAEs), while five patients with sJIA experienced six SAEs. Five patients with pJIA and one patient with sJIA reported serious infections.

IN PRACTICE:

The authors concluded that subcutaneous tocilizumab treatment provided long-term disease control in patients with pJIA or sJIA, with a safety profile consistent with past studies of tocilizumab.

SOURCE:

The study was led by Hermine I. Brunner, MD, director of the Division of Rheumatology at Cincinnati Children’s Hospital Medical Center. It was published online in Rheumatology (Oxford).

LIMITATIONS:

The open-label design and lack of a control group limited the analysis. Only a few patients continued the treatment for 5 years.

CORRECTED April 7, 2024 // An earlier version of this article misstated the clinical factors of children with CNO that were significantly associated with the need for second-line treatment, as well as the scope of assessments of aspects of disease involvement and their relationship to total number of days on NSAID monotherapy and the odds of needing a second-line treatment.

Children with chronic nonbacterial osteomyelitis (CNO) who had symmetric bone lesions or multiple affected body regions were more likely to need second-line treatment than were patients without these features, according to findings presented at the annual scientific meeting of the Childhood Arthritis and Rheumatology Research Alliance.

CNO is an auto-inflammatory condition that results in sterile inflammatory bone lesions and most commonly affects the long bones of people who are skeletally immature. After a first-line treatment of nonsteroidal anti-inflammatory drugs (NSAIDs), second-line treatments per CARRA guidelines typically include methotrexate or sulfasalazine, tumor necrosis factor (TNF)–alpha inhibitors, and bisphosphonates.

“Since it’s common for there to be long delays before diagnosis of CNO, it is important to start an effective treatment promptly,” Katherine D. Nowicki, MD, of Children’s Hospital Colorado, Aurora, told attendees. “While we have guidance on which treatments to use, it remains unclear which patients are most likely to respond to NSAIDs and which patients will require a second-line treatment.”
 

Findings Helpful for Counseling

Melissa S. Oliver, MD, MS, assistant professor of clinical pediatrics in rheumatology at Riley Children’s Health at Indiana University Health, Indianapolis, who was not involved in the research, said the findings of this study are helpful in “counseling families and patients at that initial visit and having a lower threshold to start a second-line agent if NSAID monotherapy is not working well.”

There are no clinical trials on patients with CNO, Dr. Oliver said, so very little data exist for guiding clinicians on the best therapy to use and how long to keep patients on therapy while minimizing risk for flare when coming off therapy.

A key clinical takeaway for clinicians is being able to tell patients with unifocal disease that they may not need to be on NSAIDs for a long period and can still do well, Dr. Oliver said. For patients with multifocal disease with symmetric bone lesions or multiple regions involved with CNO, “pediatric rheumatologists should have a lower threshold to start a second-line therapy for these patients,” she said.

Findings From Largest Single-Center Cohort in North America

Their topline findings revealed that patients with unifocal disease at diagnosis required 47% fewer total days of NSAID monotherapy treatment than those with multifocal disease at diagnosis, Dr. Nowicki told attendees. Having symmetric bone lesions increased the likelihood of needing a second-line therapy by 6.86 times compared with those without symmetric bone lesions, and for each additional region affected by CNO, the odds of needing a second-line therapy increased by a factor of 1.94, she said.

There were no significant differences in patient ages or sex or in mean interval from symptom onset to treatment onset across treatment groups. However, patients who received second-line treatment did have a significantly longer average time from symptom onset to diagnosis (324 days) than those who had a short course (119 days) or long course (270 days) of NSAIDs (P = .023). Mean follow-up was also significantly longer for patients with second-line treatment (3.8 years) or long-course NSAIDs (2.7 years) than for those with short-course NSAIDs (1.2 years; P < .001).

Mean erythrocyte sedimentation rate or C-reactive protein did not differ across treatment groups nor did presence of a CNO lesion on x-rays at presentation. But significantly more patients in the second-line group had a biopsy (94%) than in the long-course (74%) or short-course (69%) NSAID groups (P = .0025). They were also more likely to have one or more whole-body MRIs. Most of the patients on short-course (88%) and long-course (82%) NSAIDs did not undergo a whole-body MRI, whereas most patients (59%) on a second-line treatment underwent at least one and 24% underwent three or more MRIs (P < .001).

More patients on short-course NSAIDs had unifocal disease at diagnosis (72%) than those on long-course NSAIDs (47%) or a second-line treatment (41%; P = .015). Patients on a second-line treatment were also more likely to have symmetric involvement in the same bone (73% vs 16% short-course and 23% long-course NSAIDs) and to have more regions of the body affected (P < .001).

There were significant differences in mean days on NSAID monotherapy and number of NSAIDs trialed. Patients on a second-line treatment had a mean 441 days of NSAID monotherapy compared with 175 days for patients on short-course NSAIDs and 725 for patients on long-course NSAIDs (P < .001). Nearly all the short-course patients (94%) trialed a single NSAID, while more than half the long-course and second-line patients trialed two or more (P < .001).

None of the patients on short-course NSAIDs had complications. More patients on second-line treatments had vertebral height loss (20%) or amplified pain (14%) than long-course patients (13% and 5%, respectively; P = .02).

At the study’s end date, nearly all the patients on short-course NSAIDs were in remission (94%) compared with 71% of patients on long-course NSAIDs and only half of patients (51%) on the second-line treatment (P < .001). None of the patients on short-course NSAIDs had active disease compared with 11% of patients on long-course NSAIDs and 20% of patients on second-line treatments (P = .02).

This study included the largest single-center cohort of patients with CNO in North America, all treated at a multidisciplinary clinic with a protocolized treatment approach, but it remains limited by its retrospective nature and the missing data for 70 patients, Dr. Nowicki said. She noted that whole-body MRI was not systematically performed on all patients, so it was possible patients without a whole-body MRI had undetected asymptomatic lesions.

Despite these limitations, Dr. Oliver said retrospective studies like these can help pediatric rheumatologists get an idea of reasonable therapies to start, how long to keep patients on them, and when to escalate to the next step.

“I hope one day our CNO research will be able to tell us about which is the optimal second-line therapy for patients, such as bisphosphonates vs TNF inhibitors vs DMARDs [disease-modifying antirheumatic drugs],” Dr. Oliver said.

In 1974, Tommy John of the Los Angeles Dodgers was 31 and a 12-year veteran of Major League Baseball when he became the unwitting vanguard of a revolution in baseball and orthopedics. Fifty years later, Mr. John might not be a candidate for the latest advances to a procedure that bears his name.

The southpaw pitcher had faced the abrupt end of his career when, after one fateful delivery, he found himself unable to throw to home. So he took a gamble on the surgical equivalent of a Hail Mary: the reconstruction of a torn ligament in his pitching elbow.

The experiment was a wild success. Mr. John pitched— and better than he had before — for another 14 seasons, retiring in 1989 at the age of 46. How much better? After the surgery, he tallied three 20-win seasons compared with none before the operation, and he finished among the top five vote-getters for the annual Cy Young Award three times. He was named an All-Star once before the surgery and three times after.

The triumph notwithstanding, Tommy John now cautions against Tommy John surgery. What’s given him and clinicians pause is a trend in recent years of ever-younger athletes who undergo the procedure.

Along with the surgical improvements in repairing a torn ulnar collateral ligament (UCL) is a demographic shift toward school-aged athletes who get it. By 2014, one study concluded that 67.4% of UCL reconstruction surgeries were performed on athletes between 16 and 20 years of age. Some patients are still in Little League when they undergo the procedure.

Experts say these athletes have weakened their UCLs through overuse. They disagree on whether to call it an “epidemic,” but if it is, “the vaccine is awareness” against throwing too hard and too often, said Eric Makhni, MD, an orthopedic surgeon at Henry Ford Health in Detroit.
 

From Career-Ending to Routine

Mr. John’s entry into baseball and orthopedic lore was initially slow, but the trickle turned into a tide. After Frank Jobe, MD, swapped a healthy tendon from John’s right wrist for his worn and torn left UCL on September 25, 1974, he didn’t perform his second surgery for another 1194 days. By the time “Tommy John surgery” became a recognized phrase, Mr. John was still active but only 14 professional baseball players had undergone the operation.

Prior to the start of spring training this year, an oft-cited database listed 366 pro players who’d undergone the operation. 

“Before Tommy John, that was a career-ending injury,” said Grant E. Garrigues, MD, an orthopedic surgeon at Midwest Orthopaedics at RUSH in Chicago, who called Mr. John “a pure revolutionary.”

Tommy John surgery is “the only one that I can think of that is named after the patient rather than the doctor who first did it,” said Patrick McCulloch, MD, an orthopedic surgeon in Houston and a team physician for the Astros.

Dr. McCulloch, who performs about 25 UCL repairs a year, said that by recent estimates, one-third of pro pitchers had had some sort of surgical repair. He hesitated to call the increasing number of operations an epidemic but acknowledged that the ingredients exist for more elbow trauma among baseball players.

“More people are playing more often, and people are bigger and stronger and throwing harder,” he said.

Either way, Dr. McCulloch said, “the procedure is a victim of its own success” because it is “just done phenomenally well.”

The surgery is now commonplace — perhaps too commonplace, said David W. Altchek, MD, attending surgeon and co-chief emeritus at Hospital for Special Surgery in New York City.

Dr. Altchek played a key role in the popularity of the operation. Twenty-two years after Mr. John’s surgery, he helped develop a variation of the procedure called the docking technique. 

Whereas Dr. Jobe sutured Mr. John’s replacement graft to itself, “we developed a different way of tying it over a bone bridge, which was more secure and more easy to tension,” Dr. Altchek explained.

The advance meant less drilling into bone and enabled surgeons to avoid moving a problem-free ulnar nerve or removing the flexor-pronator muscle that protects the elbow from stress. “The trauma of the surgery is significantly less,” he said. “We just made it a lot easier very quickly,” cutting the surgery time from 2 hours to 30-40 minutes.

Maybe the surgery became too easy, said Dr. Altchek, who estimates he has done 2000 of them over the past 30 years. “I don’t want to condemn my colleagues, but there are a lot of people doing the surgery,” he said. “And not a lot of people are doing a lot of them, and they don’t know the nuances of doing the surgery.”

The older procedures are known as the “full Tommy John”; each has a 12- to 18-month healing process, with a success rate of 80%-85%. Pitchers typically sit out a season while recovering.

Brandon Erickson, MD, an orthopedic surgeon at Rothman Orthopaedic Institute in New York City, said that in younger patients he has recently turned more often to the suture of the future: an internal brace that provides a repair rather than reconstruction.

The procedure, pioneered by Felix H. Savoie III, MD, the Ray J. Haddad Professor of Orthopaedics at Tulane University School of Medicine in New Orleans, and Jeffrey R. Dugas, MD, of Andrews Sports Medicine & Orthopaedic Center in Birmingham, Alabama, uses collagen-coated tape that looks like a shoelace and provides a scaffold that Dr. McCulloch said “is inductive to healing and growth of ligament tissue.”

The brace is intended for an “overhead” athlete (mostly baseball players but also javelin throwers and gymnasts) whose UCL is torn on only one side but is otherwise in good shape. In a pitcher the same age as Mr. John was when Dr. Jobe performed the first procedure, “that ligament may not be of very good quality,” Dr. McCulloch said. “It may have thickened. It may have calcifications.” But for a high-school junior with aspirations to pitch in college or beyond without “way too many miles on the elbow,” the approach is a good fit. The healing process is as little as 6 months.

“The ones who have a good ligament are very likely to do well,” said Dr. Erickson, an assistant team doctor for the Philadelphia Phillies.

“If the patient’s ligament is generally ‘good’ with only a tear, the InternalBrace procedure may be used to repair the native ligament. On the other end of the spectrum, if the patient’s ligament is torn and degenerative the surgeon may opt to do a UCL reconstruction using an auto or allograft — ie, Tommy John surgery,” Allen Holowecky, senior product manager of Arthrex of Naples, Florida, the maker of the InternalBrace, told this news organization. “Before UCL repair, Tommy John surgery was the only real treatment option. We tend to see repairs done on younger patients since their ligament hasn’t seen years of use-damage.”
 

Calls for Caution

Tommy John III wanted to play baseball like his dad until near-fatal complications from shoulder surgery altered his path. He was drawn to chiropractic and consults on injury prevention. “All surgeries and all medical interventions are cut first, ask questions later,” he said. “I was born with that.”

He saw his dad’s slow, heroic comeback from the surgery and described him as the perfect candidate for Dr. Jobe’s experiment. Tommy John spent his recovery time squeezing Silly Putty and throwing tennis balls. “He was willing to do anything necessary. He wanted to throw. That was his brush.” When the son was recovering from his own injury, “he said, ‘Learn the knuckleball.’ I said, ‘I don’t want to. I’ve reached my point.’ ”

He said he tells young patients with UCL injuries to rest. But instead “we have year-round sports with the promise that the more you play, the better,” he said. “They’re over-activitied.”

According to the American Academy of Orthopaedic Surgeons, 6.4 million children and adolescents in the United States played organized baseball in 2022, down from 11.5 million in 2014. Nearly half of pitchers played in a league with no maximum pitch counts, and 43.5% pitched on consecutive days, the group said.

How many UCL repair or reconstruction surgeries are performed on youth athletes each year is unclear. A 2019 study, however, found that although baseball injuries decreased between 2006 and 2016, the elbow was “the only location of injury that saw an increase.”

Dr. Garrigues said some parents of throwing athletes have asked about prophylactic Tommy John surgery for their children. He said it shouldn’t apply to pitchers.

“People have taken it a little too far,” he said. Dr. Garrigues and others argue against children throwing weighted balls when coming back from surgery. Instead, “we’re shutting them down,” he said.

Throwing any pitch is an act of violence on the body, Dr. Garrigues said, with the elbow taking the final brunt of the force. “These pitchers are functioning at the absolute limits of what the human body can take,” he said. “There’s only so many bullets in a gun,” which is why pitchers often feel the twinge of a torn UCL on a routine pitch.

Dr. Makhni suggested cross-training for pitchers in the off-season instead of playing baseball year-round. “If you play soccer, your footwork is going to be better,” he said.

“Kids shouldn’t be doing this all year round,” said Rebecca Carl, MD, associate professor of pediatrics at Northwestern University Feinberg School of Medicine in Chicago. “We are recommending that kids take 2 or 3 months off.” In the off-season, she urges them to strengthen their backs and cores. 

Such advice can “feel like a bombshell,” said Dr. Carl, who chairs the Council on Sports Medicine and Fitness for the American Academy of Pediatrics. ‘Some started at a very young age. They go to camps. If I say to a teenager, ‘If you do this, I can keep you from getting injured,’ they think, ‘I won’t be injured.’” Most parents, however, understand the risk of “doing too much, too soon.”

Justin Orenduff, a former pitching prospect until his arm blew out, has made a career teaching head-to-toe pitching mechanics. He founded DVS Baseball, which uses software to teach pitchers how to properly use every muscle, starting with the orientation of the back foot. He, too, argues against pitching year-round. “Everyone on that travel team expects to get their fair share of playing time,” he said. “It just never stops.”

Organized baseball is paying attention. It has come up with the Pitch Smart program that gives maximum pitch counts for young players, but experts said children often get around that by belonging to several leagues.

Dr. Altchek said some surgeons have added platelet-rich plasma, stem cells, and bone marrow during surgery to quicken the slow healing time from UCL replacement. But he said, “it has to heal. Can you speed up biology?”

Dr. McCulloch said that, all the advances in Tommy John surgery aside, “the next frontier is really trying to crack the code on prevention.”

In 1974, Tommy John of the Los Angeles Dodgers was 31 and a 12-year veteran of Major League Baseball when he became the unwitting vanguard of a revolution in baseball and orthopedics. Fifty years later, Mr. John might not be a candidate for the latest advances to a procedure that bears his name.

The southpaw pitcher had faced the abrupt end of his career when, after one fateful delivery, he found himself unable to throw to home. So he took a gamble on the surgical equivalent of a Hail Mary: the reconstruction of a torn ligament in his pitching elbow.

The experiment was a wild success. Mr. John pitched— and better than he had before — for another 14 seasons, retiring in 1989 at the age of 46. How much better? After the surgery, he tallied three 20-win seasons compared with none before the operation, and he finished among the top five vote-getters for the annual Cy Young Award three times. He was named an All-Star once before the surgery and three times after.

The triumph notwithstanding, Tommy John now cautions against Tommy John surgery. What’s given him and clinicians pause is a trend in recent years of ever-younger athletes who undergo the procedure.

Along with the surgical improvements in repairing a torn ulnar collateral ligament (UCL) is a demographic shift toward school-aged athletes who get it. By 2014, one study concluded that 67.4% of UCL reconstruction surgeries were performed on athletes between 16 and 20 years of age. Some patients are still in Little League when they undergo the procedure.

Experts say these athletes have weakened their UCLs through overuse. They disagree on whether to call it an “epidemic,” but if it is, “the vaccine is awareness” against throwing too hard and too often, said Eric Makhni, MD, an orthopedic surgeon at Henry Ford Health in Detroit.
 

From Career-Ending to Routine

Mr. John’s entry into baseball and orthopedic lore was initially slow, but the trickle turned into a tide. After Frank Jobe, MD, swapped a healthy tendon from John’s right wrist for his worn and torn left UCL on September 25, 1974, he didn’t perform his second surgery for another 1194 days. By the time “Tommy John surgery” became a recognized phrase, Mr. John was still active but only 14 professional baseball players had undergone the operation.

Prior to the start of spring training this year, an oft-cited database listed 366 pro players who’d undergone the operation. 

“Before Tommy John, that was a career-ending injury,” said Grant E. Garrigues, MD, an orthopedic surgeon at Midwest Orthopaedics at RUSH in Chicago, who called Mr. John “a pure revolutionary.”

Tommy John surgery is “the only one that I can think of that is named after the patient rather than the doctor who first did it,” said Patrick McCulloch, MD, an orthopedic surgeon in Houston and a team physician for the Astros.

Dr. McCulloch, who performs about 25 UCL repairs a year, said that by recent estimates, one-third of pro pitchers had had some sort of surgical repair. He hesitated to call the increasing number of operations an epidemic but acknowledged that the ingredients exist for more elbow trauma among baseball players.

“More people are playing more often, and people are bigger and stronger and throwing harder,” he said.

Either way, Dr. McCulloch said, “the procedure is a victim of its own success” because it is “just done phenomenally well.”

The surgery is now commonplace — perhaps too commonplace, said David W. Altchek, MD, attending surgeon and co-chief emeritus at Hospital for Special Surgery in New York City.

Dr. Altchek played a key role in the popularity of the operation. Twenty-two years after Mr. John’s surgery, he helped develop a variation of the procedure called the docking technique. 

Whereas Dr. Jobe sutured Mr. John’s replacement graft to itself, “we developed a different way of tying it over a bone bridge, which was more secure and more easy to tension,” Dr. Altchek explained.

The advance meant less drilling into bone and enabled surgeons to avoid moving a problem-free ulnar nerve or removing the flexor-pronator muscle that protects the elbow from stress. “The trauma of the surgery is significantly less,” he said. “We just made it a lot easier very quickly,” cutting the surgery time from 2 hours to 30-40 minutes.

Maybe the surgery became too easy, said Dr. Altchek, who estimates he has done 2000 of them over the past 30 years. “I don’t want to condemn my colleagues, but there are a lot of people doing the surgery,” he said. “And not a lot of people are doing a lot of them, and they don’t know the nuances of doing the surgery.”

CORRECTED April 16, 2024 // An earlier version of this article stated incorrect percentages of patients who never received any biologics during the study's 3-year period but improved rapidly or moderately.

Early initiation of biologics — within the first 2 months of symptom presentation — appears to have a significant impact on how rapidly patients with juvenile idiopathic arthritis (JIA) improve, according to findings presented at the annual scientific meeting of the Childhood Arthritis and Rheumatology Research Alliance.

“Our study provides evidence that early use of biologics can significantly alter the disease trajectory of patients with JIA,” Mei-Sing Ong, PhD, of Harvard Medical School, Boston, told attendees. At the same time, however, not all patients who improved rapidly during a 3-year follow-up period needed biologics, a finding that Ong said the researchers are continuing to investigate.

Marinka Twilt, MD, MScE, PhD, chair of CARRA’s JIA Research Committee and a pediatric rheumatologist and clinician scientist at Alberta Children’s Hospital in Calgary, Canada, was not involved in the research but said the continued sustained remission in patients who improved rapidly is very reassuring.

Dr. Twilt

“We always wonder if initial response will be sustained or if patients tend to flare after the initial treatment,” Dr. Twilt told this news organization. “To see the sustained response up to 3 years is fantastic.” She added that it would be enlightening to see more information about patients who rapidly improved over 3 years, including whether they were still taking a [conventional disease-modifying antirheumatic drug (DMARD)] and/or biologic.

“A new diagnosis can be overwhelming for families, and this sometimes leads to step-up therapy to not overwhelm them more with information on new drugs,” Dr. Twilt said. “This study shows that an earlier start is beneficial, and this should be discussed with families early on so there is less delay in early treatment.”

Canada and many US states currently require 3 months of conventional DMARD treatment before patients can start a biologic, Dr. Twilt said, yet “this study shows the additive benefit of using a biologic within 2 months of starting a DMARD, which hopefully will lead to insurance companies adopting this threshold.”

The STOP-JIA study is a prospective observational study that compares the effectiveness of three different treatment plans for JIA. A Step-Up cohort of 257 patients received conventional antirheumatic monotherapy initially, with a biologic added at 3 months or later as needed. The Early Combination cohort of 100 patients received conventional antirheumatic therapy with a biologic from the start. The Biologic First cohort of 43 patients began taking a biologic as a first-line therapy.

In previously reported results of the study at 12 months’ follow-up, there was no significant difference between the Step-Up and Biologic First groups, but there were significant differences between the Step-Up and Early Combination groups. Significantly more patients in the Early Combination group (58.8%) than in the Step-Up group (42.8%) had inactive disease, based on the clinical Juvenile Arthritis Disease Activity Score 10 (cJADAS-10) (P = .03). Similarly, 81% of Early Combination patients achieved the American College of Rheumatology 70% improvement criteria, compared with 62% of the Step-Up patients (P = .01).

To learn whether the timing of starting a biologic influenced the disease trajectory over time, the researchers compared subgroups of patients with similar trajectories.

“Assessing treatment outcomes at a single point in time does not give us a complete picture of the effects of treatment on disease trajectory, which is an important outcome given that JIA is characterized by a relapsing-remitting course,” Dr. Ong told attendees.

Patients were sorted in the slow, moderate, or rapid improvement trajectories. In previously reported data at 12 months’ follow-up, patients’ odds of achieving rapid improvement were 3.6 times greater if they had started a biologic within 3 months.

This study compared patients’ trajectories over 3 years in the 259 patients (65% of the original cohort) who had at least one cJADAS-10 assessment in each year of follow-up. Most patients (66.8%) were in the rapid improvement class, with 25.9% in the moderate improvement class and 7.3% in the slow improvement class.

Patients in the rapid improvement group achieved inactive disease (cJADAS-10 of 2.5 or less) within 1 year and maintained inactive disease through the second and third years. The moderate and low improvement groups both had higher disease activity at baseline, but the moderate group continued to improve in years 2 and 3, with minimal disease by year 3, on the basis of the cJADAS-10 scores of 2.5-5. The slow group continued to experience moderate disease activity during years 2 and 3.

The findings also revealed that the earlier patients began a biologic, the more likely they were to be in the rapid improvement group than the slow improvement group. Participants who started a biologic in the first month had more than five times greater odds of being in the rapid improvement group than in the slow improvement group (odds ratio [OR], 5.33; P = .017).

Those who started a biologic in the second month were also more likely to be in the rapid improvement group (OR, 2.67; P = .032). For those who began a biologic by the third month, the odds of improving rapidly were not statistically significant, though Ong noted that could have been because of the small sample size. There was also no significant difference between those who improved moderately vs slowly based on when a biologic was initiated.

It would be helpful to learn whether any of the patients in the rapid improvement group were able to stop medications or whether they all continued treatment during the 3 years of follow-up, Dr. Twilt said. “Does early treatment with biologics not only lead to early remission after initiation but also to the possibility of stopping treatment earlier and remaining in remission?” she asked.

The researchers also found that not all patients needed biologics to end up in the rapid improvement group. Among patients who never received any biologics during the 3-year period, 83% improved rapidly and 17% improved moderately. Yet the researchers identified no significant differences in demographics or clinical factors between patients who received biologics and those who did not.

“The fact that there is a group of patients in the rapid response group who never need a biologic is of great interest, as we always want to treat patients early with the medications they need, but we also want to avoid overtreating patients,” Dr. Twilt said. It’s important to find out what differentiates those patients and whether it is possible to predict which patients do not need biologics early on, she said.

Dr. Ong said the research team is working to develop machine learning methods to improve risk stratification in hopes of addressing that question.

CORRECTED April 16, 2024 // An earlier version of this article stated incorrect percentages of patients who never received any biologics during the study's 3-year period but improved rapidly or moderately.

Early initiation of biologics — within the first 2 months of symptom presentation — appears to have a significant impact on how rapidly patients with juvenile idiopathic arthritis (JIA) improve, according to findings presented at the annual scientific meeting of the Childhood Arthritis and Rheumatology Research Alliance.

“Our study provides evidence that early use of biologics can significantly alter the disease trajectory of patients with JIA,” Mei-Sing Ong, PhD, of Harvard Medical School, Boston, told attendees. At the same time, however, not all patients who improved rapidly during a 3-year follow-up period needed biologics, a finding that Ong said the researchers are continuing to investigate.

Marinka Twilt, MD, MScE, PhD, chair of CARRA’s JIA Research Committee and a pediatric rheumatologist and clinician scientist at Alberta Children’s Hospital in Calgary, Canada, was not involved in the research but said the continued sustained remission in patients who improved rapidly is very reassuring.

“We always wonder if initial response will be sustained or if patients tend to flare after the initial treatment,” Dr. Twilt told this news organization. “To see the sustained response up to 3 years is fantastic.” She added that it would be enlightening to see more information about patients who rapidly improved over 3 years, including whether they were still taking a [conventional disease-modifying antirheumatic drug (DMARD)] and/or biologic.

“A new diagnosis can be overwhelming for families, and this sometimes leads to step-up therapy to not overwhelm them more with information on new drugs,” Dr. Twilt said. “This study shows that an earlier start is beneficial, and this should be discussed with families early on so there is less delay in early treatment.”

Canada and many US states currently require 3 months of conventional DMARD treatment before patients can start a biologic, Dr. Twilt said, yet “this study shows the additive benefit of using a biologic within 2 months of starting a DMARD, which hopefully will lead to insurance companies adopting this threshold.”

The STOP-JIA study is a prospective observational study that compares the effectiveness of three different treatment plans for JIA. A Step-Up cohort of 257 patients received conventional antirheumatic monotherapy initially, with a biologic added at 3 months or later as needed. The Early Combination cohort of 100 patients received conventional antirheumatic therapy with a biologic from the start. The Biologic First cohort of 43 patients began taking a biologic as a first-line therapy.

In previously reported results of the study at 12 months’ follow-up, there was no significant difference between the Step-Up and Biologic First groups, but there were significant differences between the Step-Up and Early Combination groups. Significantly more patients in the Early Combination group (58.8%) than in the Step-Up group (42.8%) had inactive disease, based on the clinical Juvenile Arthritis Disease Activity Score 10 (cJADAS-10) (P = .03). Similarly, 81% of Early Combination patients achieved the American College of Rheumatology 70% improvement criteria, compared with 62% of the Step-Up patients (P = .01).

To learn whether the timing of starting a biologic influenced the disease trajectory over time, the researchers compared subgroups of patients with similar trajectories.

“Assessing treatment outcomes at a single point in time does not give us a complete picture of the effects of treatment on disease trajectory, which is an important outcome given that JIA is characterized by a relapsing-remitting course,” Dr. Ong told attendees.

Patients were sorted in the slow, moderate, or rapid improvement trajectories. In previously reported data at 12 months’ follow-up, patients’ odds of achieving rapid improvement were 3.6 times greater if they had started a biologic within 3 months.

This study compared patients’ trajectories over 3 years in the 259 patients (65% of the original cohort) who had at least one cJADAS-10 assessment in each year of follow-up. Most patients (66.8%) were in the rapid improvement class, with 25.9% in the moderate improvement class and 7.3% in the slow improvement class.

Patients in the rapid improvement group achieved inactive disease (cJADAS-10 of 2.5 or less) within 1 year and maintained inactive disease through the second and third years. The moderate and low improvement groups both had higher disease activity at baseline, but the moderate group continued to improve in years 2 and 3, with minimal disease by year 3, on the basis of the cJADAS-10 scores of 2.5-5. The slow group continued to experience moderate disease activity during years 2 and 3.

The findings also revealed that the earlier patients began a biologic, the more likely they were to be in the rapid improvement group than the slow improvement group. Participants who started a biologic in the first month had more than five times greater odds of being in the rapid improvement group than in the slow improvement group (odds ratio [OR], 5.33; P = .017).

Those who started a biologic in the second month were also more likely to be in the rapid improvement group (OR, 2.67; P = .032). For those who began a biologic by the third month, the odds of improving rapidly were not statistically significant, though Ong noted that could have been because of the small sample size. There was also no significant difference between those who improved moderately vs slowly based on when a biologic was initiated.

It would be helpful to learn whether any of the patients in the rapid improvement group were able to stop medications or whether they all continued treatment during the 3 years of follow-up, Dr. Twilt said. “Does early treatment with biologics not only lead to early remission after initiation but also to the possibility of stopping treatment earlier and remaining in remission?” she asked.

TOPLINE:

Patients who undergo surgery for carpal tunnel syndrome (CTS) may have an increased risk of developing incident diabetes, showed a recent study.

METHODOLOGY:

• Diabetes has been shown to be a risk factor for CTS, the most common entrapment neuropathy, but it remains unclear whether CTS is associated with subsequent diabetes.
• Researchers used data from Danish national registries to evaluate the odds of developing diabetes in 83,466 patients (median age, 54 years; 67% women) who underwent surgery for CTS between January 1996 and December 2018.
• The study compared the risk of developing diabetes in patients who had CTS surgery with that of an age- and sex-matched cohort of individuals from the general population in a 1:5 ratio (n = 417,330).
• Patients were followed (median of 7.6 years) until either a diagnosis of diabetes during hospitalization or a prescription of a glucose-lowering drug, or until either death, emigration, or the end of the study period.
• Cause-specific Cox proportional hazard models were used to compare the odds of developing diabetes between the two groups.

TAKEAWAY:

• The cumulative incidence of diabetes was higher in the CTS group than in the age-matched controls (16.8% vs 10.3%).
• Patients who underwent surgery for CTS were at a higher risk of developing diabetes within 1 year of surgery (hazard ratio [HR], 1.72) and during the rest of the study period (> 1 year: HR, 1.66).
• The risk for incident diabetes after CTS surgery was higher among younger patients aged 18-39 years (adjusted HR, 2.77) than among older patients aged 70-79 years (adjusted HR, 1.29).
• Also, patients who had bilateral surgery had a higher risk of developing diabetes than the matched control population (adjusted HR, 1.86).

IN PRACTICE:

“Identifying patients who are at risk of DM [diabetes mellitus] may mediate earlier initiation of preventive strategies. However, other factors, such as obesity and A1c levels, may affect the association,” the authors wrote.

SOURCE:

The study led by Jeppe Ravn Jacobsen, MB, Rigshospitalet, University of Copenhagen, Copenhagen, Denmark, was published online in Diabetes, Obesity, and Metabolism .

LIMITATIONS:

The study did not find an association between CTS and a future diagnosis of type 1 diabetes, which may be attributed to the fact that patients younger than 18 years were excluded. A proportion of the patients who underwent CTS may have had undetected prediabetes or diabetes at the time of CTS surgery. Moreover, the registry lacked information on potential confounders such as body mass index, smoking history, and blood samples. The association between CTS and diabetes may be attributable to shared risk factors for both, such as obesity.

DISCLOSURES:

The study was funded by an internal grant from the Department of Cardiology, Rigshospitalet, University of Copenhagen, Denmark. The authors declared no conflicts of interest.

Physiotherapy conducted via video conference is noninferior to in-person sessions for the treatment of chronic knee pain, according to new research.

In the trial, participants assigned to in-person or telehealth sessions had similar improvements in knee pain and physical function over 3 months, while the online group had better session attendance and reported higher convenience.

While the COVID-19 pandemic increased the use of telerehabilitation physiotherapy services, it is not clear how these teleservices will be utilized moving forward, the study authors wrote. There is some research suggesting that both in-person and online physiotherapy are equally effective, but surveys suggest that both providers and patients remain unconvinced.

“Based on pandemic telerehabilitation experiences, less than half of allied health clinicians believe telerehabilitation is as effective as in-person care and almost half of patients think video conferencing with a physiotherapist provides lower quality care,” study first author Rana Hinman, PhD, professor of physiotherapy at the University of Melbourne, Australia, and colleagues wrote in their report published online in The Lancet.
 

‘A Game Changer’ for Physical Therapy

Commenting on the study for this news organization, Daniel White, ScD, an associate professor in the department of physical therapy at the University of Delaware in Newark, Delaware, called the research “a game changer” for physical therapy. 

“It’s showing that in-person care can be replicated in terms of efficacy,” in telehealth settings, he said. “From a telehealth perspective, it really opens the doors to access to people who have difficulty reaching physical therapists,” he added, “and puts us on stage with other modes of telehealth that are given as part of modern medicine.”

Dr. White noted that physical therapy treatment for knee osteoarthritis is underused, with just 10% of patients seeing a physical therapist prior to undergoing knee replacement. While knee replacements are effective interventions, he said, access to physical therapy could allow many patients to put off having surgery.

The findings not only provide solutions for access issues but also assuage concerns “that you’re going to get ‘physical therapy lite’” with telehealth, Dr. White added. 

“You can deliver physical therapy to this group that typically is not getting enough of it,” he said, “and it is just as effective when delivered online than if it were to be delivered in person.”
 

Noninferiority Maintained at 9 Months’ Follow-up

To understand how video conferencing physiotherapy consultations compared to in-person care, the researchers designed a non-inferiority randomized controlled trial. 

For the trial, researchers enrolled 394 adults with chronic knee pain who were aged ≥ 45 years, had activity-related joint pain, and either had no morning stiffness or morning stiffness lasting < 30 minutes. Other inclusion criteria were history of knee pain of ≥ 3 months, knee pain most days of the previous month, average walking pain score of four or more on the 11-point numeric rating scale (NRS) over the previous week, and difficulty walking and climbing stairs.

Participants also needed access to a computer device with internet as well as the ability to travel to the nearest trial physiotherapist.

The study recruited 15 physiotherapists across 27 practices in metropolitan Queensland and Victoria, Australia, of which 60% had no previous telerehabilitation experience. Physiotherapists were trained to conduct video sessions via e-learning, practice video consultations, and a competency video conferencing evaluation.

Participants were randomly assigned to in-person or video physiotherapist consultations, with both groups receiving five consultations over 3 months. All clients were prescribed a home-based strength training program and physical activity plan.

The primary outcomes were changes at 3 months in patient-reported knee pain (on a scale of 0-10), with an inferiority margin of 0.95, and physical function — assessed using the Western Ontario and McMaster Universities Arthritis Index (WOMAC) — with an inferiority margin of −5.44.

From December 10, 2019, to June 17, 2022, 204 participants were assigned to in-person sessions and 190 were assigned to telerehabilitation. At 3 months, both groups reported improved pain and physical function, with no significant differences between the two groups with either measure. The mean between-group difference was 0.16 (95% CI, −0.26 to 0.57) for knee pain and 1.65 (−0.23 to 3.53) for physical function. Noninferiority was also maintained at 9 months’ follow-up.

The trial took place over the COVID-19 pandemic, which limited participant ability to attend in-person consultations. In total, 84% of participants assigned to in-person rehabilitation attended at least three or more consultations compared with 96% of those assigned to telerehabilitation. In an additional analysis including only participants attending three or more sessions, improvement in knee pain and physical function was similar between the in-person or tele-rehabilitation groups “showing that the findings are robust,” the authors noted.

At 3 months, the telerehabilitation group ranked their sessions as more convenient that their in-person counterparts and reported greater adherence to their strengthening program. At 9 months’ follow-up, the telerehabilitation group had higher physical activity scores than the in-person group.

This research was funded by the Australian National Health and Medical Research Council. Two authors reported grant funding paid to the University of Melbourne from the National Health & Medical Research Council, Australian Research Council, Medical Research Future Fund, and Medibank for research. Dr. White has been a paid speaker for Viatris.

Physiotherapy conducted via video conference is noninferior to in-person sessions for the treatment of chronic knee pain, according to new research.

In the trial, participants assigned to in-person or telehealth sessions had similar improvements in knee pain and physical function over 3 months, while the online group had better session attendance and reported higher convenience.

While the COVID-19 pandemic increased the use of telerehabilitation physiotherapy services, it is not clear how these teleservices will be utilized moving forward, the study authors wrote. There is some research suggesting that both in-person and online physiotherapy are equally effective, but surveys suggest that both providers and patients remain unconvinced.

“Based on pandemic telerehabilitation experiences, less than half of allied health clinicians believe telerehabilitation is as effective as in-person care and almost half of patients think video conferencing with a physiotherapist provides lower quality care,” study first author Rana Hinman, PhD, professor of physiotherapy at the University of Melbourne, Australia, and colleagues wrote in their report published online in The Lancet.
 

‘A Game Changer’ for Physical Therapy

Commenting on the study for this news organization, Daniel White, ScD, an associate professor in the department of physical therapy at the University of Delaware in Newark, Delaware, called the research “a game changer” for physical therapy. 

“It’s showing that in-person care can be replicated in terms of efficacy,” in telehealth settings, he said. “From a telehealth perspective, it really opens the doors to access to people who have difficulty reaching physical therapists,” he added, “and puts us on stage with other modes of telehealth that are given as part of modern medicine.”

Dr. White noted that physical therapy treatment for knee osteoarthritis is underused, with just 10% of patients seeing a physical therapist prior to undergoing knee replacement. While knee replacements are effective interventions, he said, access to physical therapy could allow many patients to put off having surgery.

The findings not only provide solutions for access issues but also assuage concerns “that you’re going to get ‘physical therapy lite’” with telehealth, Dr. White added. 

“You can deliver physical therapy to this group that typically is not getting enough of it,” he said, “and it is just as effective when delivered online than if it were to be delivered in person.”
 

Noninferiority Maintained at 9 Months’ Follow-up

To understand how video conferencing physiotherapy consultations compared to in-person care, the researchers designed a non-inferiority randomized controlled trial. 

For the trial, researchers enrolled 394 adults with chronic knee pain who were aged ≥ 45 years, had activity-related joint pain, and either had no morning stiffness or morning stiffness lasting < 30 minutes. Other inclusion criteria were history of knee pain of ≥ 3 months, knee pain most days of the previous month, average walking pain score of four or more on the 11-point numeric rating scale (NRS) over the previous week, and difficulty walking and climbing stairs.

Participants also needed access to a computer device with internet as well as the ability to travel to the nearest trial physiotherapist.

The study recruited 15 physiotherapists across 27 practices in metropolitan Queensland and Victoria, Australia, of which 60% had no previous telerehabilitation experience. Physiotherapists were trained to conduct video sessions via e-learning, practice video consultations, and a competency video conferencing evaluation.

Participants were randomly assigned to in-person or video physiotherapist consultations, with both groups receiving five consultations over 3 months. All clients were prescribed a home-based strength training program and physical activity plan.

The primary outcomes were changes at 3 months in patient-reported knee pain (on a scale of 0-10), with an inferiority margin of 0.95, and physical function — assessed using the Western Ontario and McMaster Universities Arthritis Index (WOMAC) — with an inferiority margin of −5.44.

From December 10, 2019, to June 17, 2022, 204 participants were assigned to in-person sessions and 190 were assigned to telerehabilitation. At 3 months, both groups reported improved pain and physical function, with no significant differences between the two groups with either measure. The mean between-group difference was 0.16 (95% CI, −0.26 to 0.57) for knee pain and 1.65 (−0.23 to 3.53) for physical function. Noninferiority was also maintained at 9 months’ follow-up.

The trial took place over the COVID-19 pandemic, which limited participant ability to attend in-person consultations. In total, 84% of participants assigned to in-person rehabilitation attended at least three or more consultations compared with 96% of those assigned to telerehabilitation. In an additional analysis including only participants attending three or more sessions, improvement in knee pain and physical function was similar between the in-person or tele-rehabilitation groups “showing that the findings are robust,” the authors noted.

At 3 months, the telerehabilitation group ranked their sessions as more convenient that their in-person counterparts and reported greater adherence to their strengthening program. At 9 months’ follow-up, the telerehabilitation group had higher physical activity scores than the in-person group.

Some doctors may be scratching their heads over a new analysis reporting that combined calcium and vitamin D (CaD) supplements appear to be associated with a slight 6% increase in cardiovascular (CVD) mortality, a slight 7% decrease in cancer risk, and no effect on osteoporotic fracture in postmenopausal women.

The study, in Annals of Internal Medicine, found no effect of supplementation on all-cause mortality.

The findings emerged from an analysis of more than 20 years’ follow-up data on a randomized trial in postmenopausal women conducted as part of the Women’s Health Initiative (WHI).

Cynthia A. Thomson, PhD, RD, first author and cancer prevention scientist at the Arizona Cancer Center and a professor of health promotion sciences at the University of Arizona in Tucson said the findings recommend individualized assessment of the need for supplements for older women as they consider them in hopes of preventing fractures.

Study Details

The investigators conducted postintervention follow-up of the WHI’s 7-year multicenter randomized intervention trial of CaD vs placebo.

Since existing evidence of long-term health outcomes was limited, the trial, begun in 1999 and closed in 2005, enrolled 36,282 postmenopausal women (mean age 62) with no history of breast or colorectal cancer. They were randomly assigned 1:1 to supplementation with 1000 mg of calcium carbonate (400 mg elemental calcium) plus 400 IU of vitamin D3 daily or placebo, taken twice daily in half doses.

Study outcomes were incidence of CRC, total and invasive breast cancer; disease-specific and all-cause mortality; total CVD; and hip fracture measured through December 2020, with analyses stratified by personal supplement usage.

Cancer. CaD was associated with reduced incident total cancer, CRC, and invasive breast cancer — notably among participants not taking CaD before randomization. Cancer incidence estimates varied widely, the authors noted, when stratified by supplement use before randomization. Noting that CaD seemed to have more cancer-related impact in those without prior supplementation, the authors suggested supplementation may affect cancer biology primarily by augmenting nutrient insufficiency.

An estimated 7% reduction in cancer mortality was observed after a median cumulative follow-up of 22.3 years: 1817 vs 1943 deaths (hazard ratio, 0.93; 95% CI, 0.87-0.99).

CVD. An estimated 6% increase in CVD mortality was seen in the CaD group: 2621 vs 2420 deaths (HR, 1.06; 95% CI, 1.01-1.12). Pretrial supplement users were found to be at higher CVD risk.

Hip fracture. No effect on hip fracture risk was measured, but the authors cautioned that hip fracture and CVD outcomes were available only for a subset of participants, and the effects of calcium alone vs vitamin D alone vs the combination could not be disentangled.

In a small subgroup analysis, some CaD users were seen to respond in terms of bone mineral density but since only 4 of the study’s 40 sites collected such information, the study was underpowered to examine the effect. ”Many other studies, however, show a response to supplementation in women who already have bone mineral deficits,” Dr. Thomson said.
 

The Calcification Question

One of the possible mechanisms of harm is that high-dose calcium supplements can increase the rate of blood coagulation and promote vascular calcification, said Emma Laing, PhD, RD, director of dietetics at the University of Georgia in Athens and a spokesperson for the Chicago-based Academy of Nutrition and Dietetics.

University of Georgia

“Other factors that should be considered when determining a patient’s CVD risk are race, genetic predisposition, medical and social history, response to stress, and lifestyle behaviors, as well as the length of time supplements have been consumed,” added Dr. Laing, who was not involved in the WHI analysis.

“We asked ourselves if CaD supplements might contribute to calcification of the coronary arteries, since some believe this to be the case, although the literature is mixed,” said Dr. Thomson.

“So we did a shorter ancillary study in a small sample of several hundred [women] to see if there was any increase in calcification” and no difference was seen on imaging across the two arms. “However, women who were already on supplements before entering the study seemed to be at higher CVD risk,” she said.

Added study coauthor JoAnn E. Manson, MD, DrPH, chief of the division of preventive medicine at Brigham and Women’s Hospital and professor of women’s health at Harvard Medical School, both in Boston: “With no increase or decrease in coronary artery calcium at the end of the trial, we don’t believe starting or continuing calcium/vitamin D supplements should require screening for coronary artery disease.”

Vitamin D Supplementation

As for vitamin D only supplementation, an updated meta-analysis including more than 83,000 individuals showed that it confers no cardiovascular protection and is therefore not indicated for this purpose.
 

Practice Considerations

Offering an outsider’s perspective, Sarah G. Candler, MD, MPH, an internist in Houston specializing in primary care for older high-risk adults, said: “Unfortunately, this latest study continues the trend of creating more questions than answers. If the adverse outcome of CVD death is a result of supplementation, it is unclear if this is due to the vitamin D, the calcium, or both. And it is unclear if this is dose dependent, time dependent, or due to concurrent risk factors unique to certain populations.

Dr. Candler

“It is recommended that patients at risk of osteoporosis based on age, sex, medications, and lifestyle be screened for osteoporosis and treated accordingly, including supplementation with CaD,” Dr. Candler said. “It remains unclear whether supplementation with CaD in the absence of osteoporosis and osteopenia is net beneficial or harmful, and at this time I would not recommend it to my patients.” 

Added Dr. Manson: “The very small increase seen in cardiovascular mortality wouldn’t be a reason to discontinue supplementation among women who have been advised by their healthcare providers to take these supplements for bone health or other purposes.

“Among those at usual risk of fracture, we recommend trying to obtain adequate calcium and vitamin D from food sources first and to use supplements only for the purpose of filling gaps in intake,” Dr. Manson continued. Overall, the findings support the national recommended dietary allowances for daily calcium intake of 1200 mg and daily vitamin D intake of 600-800 IU among postmenopausal women for maintenance of bone health, she said.

While a 2022 study found that vitamin D supplementation alone did not prevent fractures in healthy adults, other research has shown that a calcium/vitamin D combination is more likely to protect the skeleton.

“Patients at risk for fractures will probably benefit from calcium and/or vitamin D supplementation if they do not meet dietary intake requirements, have malabsorption syndromes, are taking medications that affect nutrient absorption, or if they are older and not regularly exposed to sunlight,” said Dr. Laing. “A combination of biochemical, imaging, functional, and dietary intake data can help determine if a supplement is warranted.”

She stressed that additional research is needed in more diverse populations before changing practice guidelines. “However, doctors should continue to weigh the risks and benefits of prescribing supplements for each patient.”

Multiple authors reported grant support from government funding agencies. The outside commentators had no relevant competing interests to disclose.

The US Food and Drug Administration (FDA) has approved the biosimilar tocilizumab-aazg (Tyenne), Fresenius Kabi, the drug’s manufacturer, announced on March 7.

This is the second tocilizumab biosimilar approved by the regulatory agency and the first to be approved in both intravenous (IV) and subcutaneous formulations that are available with the reference product, Actemra, the company said in a press release.

Tocilizumab-aazg is an interleukin-6 (IL-6) receptor antagonist indicated for:

• Adults with moderate to severe rheumatoid arthritis who have had an inadequate response to one or more disease-modifying antirheumatic drugs
• Adults with giant cell arteritis
• Patients aged 2 years or older with active polyarticular juvenile idiopathic arthritis
• Patients aged 2 years or older with active systemic juvenile idiopathic arthritis

“Fresenius Kabi is leading the way as the first company to receive FDA approval for both IV and subcutaneous formulations of its tocilizumab biosimilar and is available in prefilled syringe, pen injector, and vial presentations,” Fabrice Romanet, senior vice president of innovation and development at Fresenius Kabi Biopharma, said in a statement.

The FDA approved the first tocilizumab biosimilar, manufactured by Biogen, in late September 2023. It is administered by IV infusion.

Tocilizumab-aazg’s approval was based on outcome and safety data from a dozen clinical studies. The drug can be administered via intravenous formulation (20 mg/mL) or subcutaneously via a single-dose 162-mg/0.9-mL prefilled syringe or single-dose prefilled autoinjector. 

The most common side effects for tocilizumab-aazg include upper respiratory tract infections, headache, hypertension, and injection site reactions. The most serious side effects include serious infections, perforation of the stomach or intestines, hepatotoxicity, and changes in certain lab results.

Tocilizumab-aazg has already launched in 10 countries, Fresenius Kabi shared in the press release, and plans to launch in additional countries in 2024 and 2025. It is not clear when tocilizumab-aazg will be made available in the United States.

“In accordance with its patent settlement agreement with Genentech, Fresenius Kabi has a license to market its tocilizumab products in the United States commencing on the license dates, which are confidential,” the company noted.

“In accordance with its patent settlement agreement with Genentech, Fresenius Kabi has a license to market its tocilizumab products in the United States commencing on the license dates, which are confidential,” the company noted.

A 73-year-old man with hypertension is evaluated for right great toe pain. A tap of the toe reveals uric acid crystals. He has a history of hypertension and hyperlipidemia. His current medications are hydrochlorothiazide, amlodipine, and atorvastatin.

Which blood pressure medication would you recommend to replace his hydrochlorothiazide?

A. Furosemide

B. Chlorthalidone

C. Lisinopril

D. Losartan

E. Irbesartan

Losartan

Diuretics should be avoided if possible in a patient with gout, as they increase uric acid levels. Of the other three options, losartan offers the added benefit of lowering uric acid levels. Losartan has uricosuric effects — a property that is unique to losartan of the angiotensin receptor blockers (ARBs) that have been studied.^1,2 The uric acid lowering appears to be a probenecid-like effect.

Losartan has also been evaluated to see whether using it in combination with a thiazide diuretic can reduce the rise in uric acid that occurs with thiazides. Matsumura and colleagues looked at data from the COMFORT trial, focusing on the effect of combining losartan with hydrochlorothiazide on uric acid levels.³ They looked at a group of 118 patients on an ARB other than losartan plus a diuretic, who were then randomly assigned to losartan 50 mg/hydrochlorothiazide 12.5 mg or continuation of another ARB plus a diuretic. Blood pressure control was the same between groups, but the patients who received the losartan combination had lower uric acid levels (P = .01).

Ferreira and colleagues looked at the difference in uric acid lowering between high-dose (150 mg/day) vs low-dose losartan (50 mg/day).⁴ Compared with low-dose, high-dose losartan reduced serum uric acid by 0.27 (0.34 to 0.21) mg/dL, P < .001.
 

SGLT2 inhibitors

SGLT2 inhibitors also lower uric acid. Suijik and colleagues conducted an analysis of two randomized trials of SGLT2 inhibitors (empagliflozin and dapagliflozin), and concluded that SGLT2 inhibitors induce uric acid excretion, which is strongly linked to urinary glucose excretion.⁵

Metformin

Metformin is used as a firstline drug for the treatment of diabetes. It also has evidence for decreasing colonic polyps. Cho and colleagues looked at over 12,000 patients with diabetes over a 12-year period; 3775 underwent colonoscopies.⁶ They compared frequency of polyps in patients who were using metformin with those who were not treated with metformin. The polyp detection rate was lower in the metformin group than in the no metformin group (39.4% vs. 62.4%, P < .01).

Higurashi and colleagues performed a double-blind, placebo-controlled trial of metformin in nondiabetic patients for the prevention of colon polyps.⁷ The dose of metformin used in this study was very low (250 mg/day). There were significantly fewer adenomas in the metformin group (22 of 71 patients) than in the placebo group (32 of 62) (relative risk, 0.60; 95% confidence interval, 0.39-0.92, P = .016).
 

Thiazide diuretics

Thiazide diuretics have long been used to help prevent kidney stones in addition to treating hypertension. They decrease urinary calcium excretion, which may reduce kidney stones. Could this reduction in calcium excretion be good for bones?

Xiao and colleagues did a meta-analysis of 11 prospective studies involving 2,193,160 participants.⁸ Thiazide diuretic users had a significant 14% reduction in the risk of all fractures (RR, 0.86; 95% CI, 0.80-0.93; P = .009) and an 18% reduction in the risk of hip fracture (RR, 0.82; 95% CI, 0.80-0.93; P = .009). Kruse and colleagues found that long duration and continuity of thiazide exposure seemed to be important to obtain this protective effect on fracture risk.⁹

Pearls:

• Losartan, but not other ARBs, lowers uric acid levels and may be helpful in managing hypertension in gout patients; higher doses lower uric acid more.
• Metformin use appears to decrease colon polyp formation.
• Thiazide diuretics may reduce fracture risk while patients are taking them.

The US Food and Drug Administration has approved the first interchangeable, high-concentration, citrate-free adalimumab biosimilar, adalimumab-ryvk (Simlandi).

This is the 10th adalimumab biosimilar approved by the regulatory agency and the first biosimilar approval in the US market for the Icelandic pharmaceutical company Alvotech in partnership with Teva Pharmaceuticals.

“An interchangeable citrate-free, high-concentration biosimilar adalimumab has the potential to change the market dynamics in a rapidly evolving environment for biosimilars in the U.S.,” said Robert Wessman, chairman and CEO of Alvotech, in a company press release on February 23.

Adalimumab-ryvk was approved in the European Union in 2021 and in Australia and Canada in 2022. 

Adalimumab-ryvk is indicated for adults with rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, ulcerative colitis, Crohn’s disease, plaque psoriasis, hidradenitis suppurativa, and noninfectious intermediate and posterior uveitis and panuveitis. In pediatric patients, it is indicated for polyarticular juvenile idiopathic arthritis in children 2 years of age and older and Crohn’s disease in children 6 years of age and older.

Adalimumab-ryvk is the third Humira biosimilar overall granted interchangeability status, which allows pharmacists (depending on state law) to substitute the biosimilar for the reference product without involving the prescribing clinician. Adalimumab-adbm (Cyltezo), manufactured by Boehringer Ingelheim, and adalimumab-afzb (Abrilada), manufactured by Pfizer, were previously granted interchangeability status; however, they both are interchangeable with the low-concentration formulation of Humira, which make up only an estimated 15% of Humira prescriptions, according to a report by Goodroot. 

Adalimumab-ryvk will be launched “imminently” in the United States, according to the press release, but no specific dates were provided. It is also not yet known how the biosimilar will be priced compared with Humira. Other adalimumab biosimilars have launched with discounts from 5% to 85% of Humira’s list price.
