European agency recommends two new adalimumab biosimilars
The European Medicines Agency’s Committee for Medicinal Products for Human Use recommended marketing authorization this week for two new adalimumab biosimilars, Hukyndra and Libmyris.
The biosimilars, both developed by STADA Arzneimittel AG, will be available as a 40-mg solution for injection in a pre-filled syringe and pre-filled pen and 80-mg solution for injection in a pre-filled syringe. Both biosimilars will have 15 indications:
- rheumatoid arthritis
- polyarticular juvenile idiopathic arthritis
- enthesitis-related arthritis
- ankylosing spondylitis
- axial spondyloarthritis without radiographic evidence of ankylosing spondylitis
- psoriatic arthritis
- chronic plaque psoriasis (adults and children)
- hidradenitis suppurativa
- Crohn’s disease (adults and children)
- ulcerative colitis (adults and children)
- uveitis (adults and children)
Data show that both Hukyndra and Libmyris are highly similar to the reference product Humira (adalimumab), a monoclonal antibody to tumor necrosis factor alpha, and have comparable quality, safety, and efficacy.

U.S. seniors’ pandemic care worst among wealthy nations: Survey
Older adults in the United States – particularly among Black and Latino/Hispanic populations – experienced worse access to health care for chronic conditions during the pandemic than older adults in 10 other wealthy countries, according to findings from The Commonwealth Fund’s 2021 International Health Policy Survey of Older Adults released today.
David Blumenthal, MD, president of The Commonwealth Fund, said during a press briefing that surveying the senior population in the United States is particularly insightful because it is the only group with the universal coverage of Medicare, which offers a more direct comparison with other countries’ universal health care coverage.
More than one-third (37%) of older U.S. adults with multiple chronic conditions reported pandemic-related disruptions in their care – higher than rates in Canada, the Netherlands, and U.K. In Germany, only 11% had canceled or postponed appointments.
The survey was conducted between March and June 2021 and included responses from 18,477 adults age 65 and older in Australia, Canada, France, Germany, the Netherlands, New Zealand, Norway, Sweden, Switzerland, and U.K., and U.S. adults age 60 and older.
Among older adults who need help with daily activities, those in the United States, Canada, U.K., and Australia were the most likely to say they did not receive needed services from professionals or family members.
In the United States, 23% of people who said they needed help with activities such as housework, meal preparation, and medication management experienced a disruption in care because services were canceled or very limited during the pandemic. For comparison, only 8% of seniors in Germany and 11% of seniors in the Netherlands did not receive help with basic daily activities.
Many U.S. seniors used up savings
“Nearly one in five older adults report that they used up their savings or lost their main source of income because of the pandemic. We see much lower rates in other countries like Germany, Switzerland, the Netherlands, and Sweden,” Reginald D. Williams, vice president for international health policy and practice innovations at The Commonwealth Fund, said during a briefing.
Older U.S. adults reported economic difficulties related to the pandemic at a rate of up to six times that of other countries, he said.
The differences by race were stark. While 19% of U.S. seniors overall experienced financial hardships related to the pandemic, 32% of Black seniors and 39% of Latino/Hispanic seniors in the United States experienced hardships. Germany had the lowest rate, at 3% overall.
“As the COVID-19 pandemic in the United States continues to evolve,” Mr. Williams said, “finding ways to reduce care barriers – affordability and connecting adults to usual sources of primary care, enhancing access to economic supports and social services – can help narrow the gaps.”
Dr. Blumenthal said that even though “Medicare is a critical lifeline,” it has flaws.
“Medicare plans have significant gaps that leave beneficiaries vulnerable to sizable out-of-pocket expenses,” he said.
Placing caps on out-of-pocket costs and covering more health services, such as dental, vision, and hearing care, could help make the population less vulnerable, Dr. Blumenthal said. “The chronic lack of security facing U.S. seniors, especially those who are Black or Hispanic, is exacerbating the pandemic’s devastating toll,” he added.
Dr. Blumenthal and Mr. Williams have reported no relevant financial relationships.

Korean siblings face high familial IBD risk
Among Asian-Pacific populations, the first-degree relatives (FDRs) of individuals with inflammatory bowel disease (IBD) have a significantly increased risk for IBD themselves, according to a large analysis of data from South Korea. The greatest risk was found in siblings and for Crohn’s disease (CD).
The analysis of the South Korean Health Insurance Database included a cohort of 21,940,795 individuals from about 12 million families, with data collected between 2002 and 2017.
Previous studies have examined risk of IBD and familial relationships with existing IBD patients, but they have been subject to biases and have been heterogeneous in design, according to the authors, led by co–first authors Hyun Jung Kim, MD, of Korea University in Seoul, South Korea, and Shailja C. Shah, MD, of Vanderbilt University in Nashville, Tenn. There are few true population-based studies that quantify specific risks for family members of IBD patients, and none that were conducted in non-Western populations.
There are concerns about extrapolating familial IBD risk estimates from Western European populations to Asian populations because new data suggest that there are both genetic and nongenetic disease risk factors that reflect geography and ethnicity, the authors noted.
The researchers identified 45,717 individuals with ulcerative colitis (UC) and 17,848 with CD. Mean annual incidence rates were 4.6 cases of UC and 3.2 cases of CD per 100,000 person-years, which was relatively stable across the study period.
In all, 3.8% of UC and 3.1% of CD diagnoses occurred in FDR’s of existing patients. Among those with an FDR with IBD, the incidence of UC and CD was 54.5 and 99.2 per 100,000 person-years, respectively. When compared with individuals who had no FDRs with IBD, subjects who had an FDR with CD were at a more than 20-fold increased risk of CD (incident rate ratio, 22.2; 95% confidence interval, 20.5-24.5), whereas individuals with an FDR with UC were at a little more than a 10-fold risk for UC (IRR, 10.2; 95% CI, 9.39-11.1).
Subjects with an FDR with CD were at higher risk of UC (IRR, 3.56; 95% CI, 2.77-4.50), and those with an FDR with UC were at higher risk of CD (IRR, 2.94; 95% CI, 2.45-3.49). After adjustment for smoking, having an FDR with IBD was associated with an almost eightfold increased risk of UC (IRR, 7.94; 95% CI, 6.98-9.03) and a nearly 20-fold increased risk of CD (IRR, 19.03; 95% CI, 15.58-23.25).
The investigators also performed an analysis based on type of relative, with matching relations with unaffected relatives as the reference for each comparison. The highest risk for incident CD was with twin siblings (IRR, 336.2; 95% CI, 235.0-481.1) followed by nontwin siblings (IRR, 27.6; 95% CI, 24.6-30.9). The risk of CD among offspring of an affected father was 9.40 (95% CI, 6.81-13.0) and 6.54 (95% CI, 4.17-10.3) for offspring of affected mothers. There was a similar pattern for UC, although the magnitude was smaller: 163.7 for twin siblings (95% CI, 105.6-253.9), 13.1 for nontwin siblings (95% CI, 11.4-15.0), 7.11 for offspring of affected fathers (95% CI, 6.10-8.29), and 8.77 for offspring of affected mothers (95% CI, 7.46-10.3).
The researchers found no evidence of a birth cohort effect. Family history and IBD risk is a complicated relationship. Family history includes shared genetics as well as similar environmental exposures, and gene-environment interactions can add another layer of uncertainty. Previous studies have found that asymptomatic family members of IBD patients sometimes have preclinical signs such as changes in intestinal permeability, immune function, the microbiome, and biomarker levels.
IBD has emerged recently among Asian-Pacific populations as a serious health concern, with a recent rapid increase. This may reflect a shift in potentially modifiable environmental triggers. “Precisely quantifying familial risk and patterns might enable more accurate risk counseling and better-targeted clinical surveillance for earlier diagnosis and treatment among FDRs. Moreover, an accurate definition of familial IBD risk across populations also might inform subsequent investigations untangling the various shared environmental and genetic contributions,” the authors wrote.
Although genetic susceptibility is generally accepted as the predominant driver in familial trends for IBD, the authors noted their “study was not designed to determine the contribution of genetic vs. nongenetic determinants to familial IBD risk, and future well-designed dedicated investigations are needed to provide this clarity.”
The study is limited by the relatively short follow-up period, which may not have captured all IBD cases within patients’ families.
The authors have no relevant financial disclosures.
One of the hallmarks of effective IBD management is early disease intervention to modify the natural history. This work will be instrumental in counseling patients’ families on the need to monitor for subclinical red flag or early warning signs, and it will be important to recognize that male and female IBD patients will both need to be counseled equally on the risk of offspring developing IBD. Further work will be needed to understand whether modifiable risk factors can be identified to help prevent the development of IBD in these at-risk individuals and whether specific mutations are responsible for multilineage IBD syndromes affecting several generations or multiple first-degree relatives.

FROM CLINICAL GASTROENTEROLOGY AND HEPATOLOGY
Expert advice
I once answered online skin questions. The most popular one was, “Is my penis supposed to look like that?”
Then the site was bought by an entrepreneur with a corporate sensibility. He opened two forums: for 15 bucks, you could access the Medical Forum and ask a doctor. For 10, you could join the Community Forum and ask anybody with an opinion. One guess about which forum was more popular.
Years later, a colleague referred a fellow who had run a poison ivy website for a decade and wanted to interview a doctor. He had never spoken with one before, “because it never occurred to me.” His site featured the usual folklore: that blister fluid spreads the poison, that you can catch it from your dog. His website had many pictures. Some were in focus, and a few actually showed poison ivy.
I checked a year later and found that he had never uploaded our interview to his website. When I emailed to ask how come, he said he’d been busy, and did I want him to? I told him I was OK.
What made me think of these old episodes was a phone chat I had the other day with an IT guy about my laptop.
After I told him my problem, he said, “Since you’re a doctor, could I ask you a medical question?”
“Sure.”
“Is the COVID vaccine safe?” he asked.
“I had two shots myself,” I said, “and I’m planning a third. Does that tell you what I think about how safe it is?”
He didn’t answer, and we got back to the laptop.
Five minutes later he said, “I just wonder whether we should mess with vaccines. Maybe we should let nature take its course.”
“How about polio and diphtheria?” I said. “Should we let nature take its course with them?”
He thought for a moment and said, “If you don’t get vaccinated, can you spread the virus to other people?”
“Yes, you can,” I said. “It’s not just that you can get sick, but you can make other people sick, and possibly die if they’re old or vulnerable.”
Again, no response. We finished up with the laptop.
“Thanks for your medical advice,” he said. “I get conflicting information from so many sources.”
Yes, he does. He and everybody else always have. When the issues are poison ivy and genital blotchiness, the stakes are not high enough for anyone to talk about. To a large extent, people have always made their minds up about things based on what their friends think and tell them.

When it comes to contact dermatitis or penile blotches, you can try to straighten people out, but it doesn’t matter much if you fail.

I once answered online skin questions. The most popular one was, “Is my penis supposed to look like that?”
Then the site was bought by an entrepreneur with a corporate sensibility. He opened two forums: for 15 bucks, you could access the Medical Forum and ask a doctor. For 10, you could join the Community Forum and ask anybody with an opinion. One guess about which forum was more popular.
Years later, a colleague referred a fellow who had run a poison ivy website for a decade and wanted to interview a doctor. He had never spoken with one before, “because it never occurred to me.” His site featured the usual folklore: that blister fluid spreads the poison, that you can catch it from your dog. His website had many pictures. Some were in focus, and a few actually showed poison ivy.
I checked a year later and found that he had never uploaded our interview to his website. When I emailed to ask how come, he said he’d been busy, and did I want him to? I told him I was OK.
What made me think of these old episodes was a phone chat I had the other day with an IT guy about my laptop.
After I told him my problem, he said, “Since you’re a doctor, could I ask you a medical question?”
“Sure.”
“Is the COVID vaccine safe?” he asked.
“I had two shots myself,” I said, “and I’m planning a third. Does that tell you what I think about how safe it is?”
He didn’t answer, and we got back to the laptop.
Five minutes later he said, “I just wonder whether we should mess with vaccines. Maybe we should let nature take its course.”
“How about polio and diphtheria?” I said. “Should we let nature take its course with them?”
He thought for a moment and said, “If you don’t get vaccinated, can you spread the virus to other people?”
“Yes, you can,” I said. “It’s not just that you can get sick, but you can make other people sick, and possibly die if they’re old or vulnerable.”
Again, no response. We finished up with the laptop.
“Thanks for your medical advice,” he said. “I get conflicting information from so many sources.”
Yes, he does. He and everybody else always have. When the issues are poison ivy and genital blotchiness, the stakes are not high enough for anyone to talk about. To a large extent, people have always made their minds up about things based on what their friends think and tell them.

Nonopioid med promising for neuropathic pain
Top-line results from a phase 2 study suggest vixotrigine (BIIB074, Biogen), a nonopioid investigational oral pain medication, reduces chronic neuropathic pain caused by small fiber neuropathy (SFN) and is generally well tolerated.
“We are encouraged by the overall results of the CONVEY study, especially given the significant unmet medical need for additional agents to treat chronic painful neuropathy,” Katherine Dawson, MD, senior vice president and head of the therapeutics development unit at Biogen, said in a news release.
Vixotrigine (BIIB074) is a peripherally and centrally acting, orally administered, voltage- and use-dependent voltage-gated sodium channel blocker.
CONVEY was a phase 2, placebo-controlled, double-blind, randomized withdrawal study of 265 patients experiencing pain from confirmed idiopathic or diabetes-associated SFN.
Following a 4-week open-label run-in period, 123 responders to vixotrigine were randomly allocated to 200 mg or 350 mg vixotrigine or placebo twice daily for 12 weeks in the double-blind portion of the study.
At week 12, vixotrigine 200 mg twice daily met the primary endpoint of a statistically significant reduction from baseline in the mean average daily pain (ADP) score versus placebo (P = .0501).
A subgroup analysis showed a treatment effect in patients with diabetes-associated SFN but not in the smaller subgroup of patients with idiopathic SFN.
The 200-mg dose also led to a significant improvement over placebo in mean worst daily pain score at 12 weeks (P = .0455).
A numeric advantage of 200 mg vixotrigine over placebo was observed in additional secondary endpoints, including the proportion of patients with at least a 2-point improvement in ADP score and the proportion with at least a 30% reduction in ADP at week 12, but these failed to reach statistical significance.
Vixotrigine 350 mg twice daily did not meet the primary endpoint of mean change in ADP at 12 weeks.
However, treatment at the higher dose led to a significant increase in the proportion of patients who reported being “very much improved” or “much improved” over baseline (P = .0580), Biogen reported.
In addition, a numeric advantage of 350 mg over placebo was observed in the proportion of patients with a 2-point or greater improvement in ADP score and the proportion with at least a 30% reduction in ADP at 12 weeks, but these also did not reach statistical significance.
Both doses of vixotrigine were “generally well tolerated and the safety profile was consistent with previous studies of vixotrigine with no evidence of abuse potential,” the company said.
In the open-label period, common adverse events seen in at least 2.5% of patients were dizziness, headache, vertigo, and nausea; adverse events led 5.3% of patients to discontinue the open-label portion of the study. Across the entire study, most adverse events were mild or moderate in severity.
“The totality of data from the vixotrigine program will inform potential doses for study in future phase 3 clinical trials,” the company said.

Transfusions, readmissions higher for patients with CLL after cardiac surgery
Patients with chronic lymphocytic leukemia have similar outcomes following cardiac operations as patients without CLL, but commonly require more blood transfusions, according to the results of retrospective cohort study using the 2010-2017 Nationwide Readmissions Database (NRD).
The researchers assessed all adult patients undergoing elective coronary artery bypass grafting, valve repair, or valve replacement as identified using the NRD.
Patients were stratified by history of CLL and the incidence of in-hospital mortality, perioperative complications, blood transfusions, and readmission within 90 days were examined. A 3:1 nearest-neighbor matching was performed between patients with and without CLL for all primary and secondary outcomes of interest, according to the report, published online in Annals of Thoracic Surgery.
Comparable results
A total of 1,250,882 patients in the database were found who underwent cardiac operations. Of these, 0.23% had a diagnosis of CLL. Among 11,237 propensity-matched patients, those with CLL had similar rates of in-hospital mortality (3.8% vs. 2.6%, P = .08) and perioperative complications (33.4% vs. 33.6%, P = .92), compared with their non-CLL counterparts. However, the incidence of infection was comparable (8.5% vs. 9.4%, P = .38).
However, patients with CLL required blood transfusions more frequently (33.7% vs. 28.4%, P = .003) than did patients without CLL. In addition, patients with CLL were more likely to be readmitted within 90 days of discharge, compared with their counterparts, and “respiratory reasons, including pneumonia, contributed significantly to the readmission burden in this cohort,” the researchers, led by Josef Madrigal, BS, of the University of California, Los Angeles, stated.
“The inherent risk of transfusion and the possible benefits of blood conservation interventions must be considered in this patient population. Increased risk of rehospitalization in patients with CLL suggests the need for measures aimed at mitigating the risk of respiratory complications,” the researchers concluded.

Durvalumab combos beat monotherapy for unresectable stage 3 NSCLC
Both combinations – durvalumab plus either the anti-CD73 monoclonal antibody oleclumab or the anti-NKG2A mAb monalizumab – also numerically improved objective response rate. “Safety profiles were consistent across arms and no new safety signals were identified,” said Alexandre Martinez-Marti, MD, the lead investigator on the phase 2 trial, dubbed COAST, which he presented (abstract LBA42) at the 2021 European Society for Medical Oncology Congress on Sept. 17.
“These data support further evaluations of these combinations,” said Dr. Martinez-Marti, also a thoracic medical oncologist at the Vall d’Hebron Institute of Oncology in Barcelona.
Durvalumab is already established as a standard of care option for patients with unresectable stage 3 NSCLC who don’t progress after concurrent chemoradiation. There’s been preliminary data suggesting the benefits might be greater with oleclumab or monalizumab, so the study team looked into the issue.
They randomized 66 patients with unresectable stage 3 NSCLC and no progression after chemoradiotherapy to durvalumab 1,500 mg IV every 4 weeks; 59 others to durvalumab at the same dosage plus oleclumab 3,000 mg IV every 2 weeks for the first two cycles then every 4 weeks, and 61 were randomized to durvalumab plus monalizumab 750 mg IV every 2 weeks.
Patients were treated for up to 12 months, and they started treatment no later than 42 days after completing chemoradiation.
Over a median follow-up of 11.5 months, median progression-free survival (PFS) was 6.3 months in the durvalumab arm, but 15.1 months with the monalizumab combination (PFS hazard ratio versus durvalumab alone, 0.65; 95% CI, 0.49-0.85), and not reached in the oleclumab arm (PFS HR, 0.44; 95% CI, 0.26-0.75).
There were only a few complete responders across the study groups. Partial responses rates were 22.4% of the durvalumab alone arm, 36.7% in the oleclumab group, and 32.3% in the monalizumab arm.
The investigator assessed objective response rate was 25.4% with durvalumab alone, 38.3% in the oleclumab group, and 37.1% with the monalizumab combination. Curves started to separate from durvalumab monotherapy at around 2-4 months.
“Overall, the safety profiles of the two combinations were generally similar to the safety profile of durvalumab alone,” Dr. Martinez-Marti said. The rate of grade 3 or higher treatment-emergent events incidence was 39.4% with durvalumab, 40.7% the oleclumab combination, and 27.9% with monalizumab.
The most common grade 3/4 events were pneumonia (5.9%) and decreased lymphocyte count (3.2%); both were less common with the monalizumab combination.
Combined rates of pneumonitis and radiation pneumonitis of any grade were 21.2% with durvalumab, 28.8% in the oleclumab group, and 21.3% with monalizumab.
The groups were generally well balanced at baseline. The majority of subjects were men, White, and former smokers. Most subjects had stage 3A or 3B disease.
The work was funded by AstraZeneca. The investigators disclosed numerous ties to the company, including Dr. Martinez-Marti, who reported personal fees, travel expenses, and other connections.

Durvalumab is already established as a standard of care option for patients with unresectable stage 3 NSCLC who don’t progress after concurrent chemoradiation. There’s been preliminary data suggesting the benefits might be greater with oleclumab or monalizumab, so the study team looked into the issue.
They randomized 66 patients with unresectable stage 3 NSCLC and no progression after chemoradiotherapy to durvalumab 1,500 mg IV every 4 weeks; 59 others to durvalumab at the same dosage plus oleclumab 3,000 mg IV every 2 weeks for the first two cycles then every 4 weeks, and 61 were randomized to durvalumab plus monalizumab 750 mg IV every 2 weeks.
Patients were treated for up to 12 months, and they started treatment no later than 42 days after completing chemoradiation.
Over a median follow-up of 11.5 months, median progression-free survival (PFS) was 6.3 months in the durvalumab arm, but 15.1 months with the monalizumab combination (PFS hazard ratio versus durvalumab alone, 0.65; 95% CI, 0.49-0.85), and not reached in the oleclumab arm (PFS HR, 0.44; 95% CI, 0.26-0.75).
There were only a few complete responders across the study groups. Partial responses rates were 22.4% of the durvalumab alone arm, 36.7% in the oleclumab group, and 32.3% in the monalizumab arm.
The investigator assessed objective response rate was 25.4% with durvalumab alone, 38.3% in the oleclumab group, and 37.1% with the monalizumab combination. Curves started to separate from durvalumab monotherapy at around 2-4 months.
“Overall, the safety profiles of the two combinations were generally similar to the safety profile of durvalumab alone,” Dr. Martinez-Marti said. The rate of grade 3 or higher treatment-emergent events incidence was 39.4% with durvalumab, 40.7% the oleclumab combination, and 27.9% with monalizumab.
The most common grade 3/4 events were pneumonia (5.9%) and decreased lymphocyte count (3.2%); both were less common with the monalizumab combination.
Combined rates of pneumonitis and radiation pneumonitis of any grade were 21.2% with durvalumab, 28.8% in the oleclumab group, and 21.3% with monalizumab.
The groups were generally well balanced at baseline. The majority of subjects were men, White, and former smokers. Most subjects had stage 3A or 3B disease.
The work was funded by AstraZeneca. The investigators disclosed numerous ties to the company, including Dr. Martinez-Marti, who reported personal fees, travel expenses, and other connections.

Mediastinal relapse risk lower with PORT, but no survival benefit
The report was an update on the LungART international clinical trial, which, at the 2020 ESMO meeting, was shown not to improve disease-free survival over the course of 3 years. The update showed that, in addition to the lack of disease-free survival benefit, there was also no difference in metastases, and patients randomized to PORT had higher rates of death and grade 3/4 cardiopulmonary toxicity. The investigators returned this year to expand on another finding from the trial, a 51% reduction in the risk of mediastinal relapse with postoperative radiotherapy. The new analysis suggests there might still be a role for PORT in select patients, perhaps those with heavy nodal involvement, said lead investigator and presenter Cecile Le Pechoux, MD, radiation oncologist at the Gustave Roussy cancer treatment center in Villejuif, France.
For now, “personalized prescription of PORT should be based on prognostic factors of relapse and joint assessment of toxicity and efficacy,” she said.
Study discussant Pilar Garrido, MD, PhD, head of thoracic tumors Ramon y Cajal University Hospital, Madrid, agreed that there might still be a benefit for people with multiple N2 nodal station involvement, but at present, she said, “for me PORT cannot be the standard of care ... given the toxicity and mortality among PORT patients in LungART.”
The trial randomized 501 patients with non–small cell lung cancer with mediastinal involvement to either PORT at 54 Gy over 5.5 weeks or no further treatment following complete resection. Neoadjuvant or adjuvant chemotherapy were allowed.
The 3-year mediastinal relapse-free survival was 72.26% in the control arm but 86.06% with PORT (hazard ratio, 0.45; 95% confidence interval, 0.3-0.69).
“There is a significant difference” when it comes to mediastinal relapse, and “patients who have PORT do better. If we look at the location of mediastinal relapse, most [patients] relapse within the initially involved node. This is important information,” Dr. Le Pechoux said.
For left-sided tumors, the most frequent sites of mediastinal relapse were thoracic lymph node stations 7, 4L, and 4R. For right sided tumors, the most frequent stations were 4R, 2R and 7.
Prognostic factors for disease-free survival included quality of resection, extent of mediastinal involvement, and lymph node ratio (involved/explored). Nodal involvement was a significant prognostic factor for overall survival, but PORT was not (HR, 0.98; 95% CI, 0.7-1.4).
Mediastinal involvement with more than two node stations and less than an RO, or microscopically margin-negative resection, increased the risk of relapse.
The work was funded by the French National Cancer Institute, French Health Ministry, Institute Gustave Roussy, and Cancer Research UK. Dr. Pechoux and Dr. Garido disclosed ties to AstraZeneca, Roche, Amgen, and other companies.

FROM ESMO CONGRESS 2021
‘New first-line standard of care’ in cervical cancer
That declaration was made by Raza Mirza, MD, chief oncologist at Copenhagen University Hospital in Denmark, who was invited to discuss the pros and cons of the KEYNOTE-826 trial at the European Society for Medical Oncology (ESMO) Congress 2021.
The trial showed that adding the checkpoint inhibitor pembrolizumab (Keytruda) to standard chemotherapy — with or without bevacizumab — resulted in about a one third reduction in the risk for both disease progression and death compared with chemotherapy alone.
The benefit of adding pembrolizumab was seen both in the overall study population and in patients with higher levels of programmed death ligand-1 (PD-L1), but not in those with biomarker-negative tumors, reported investigator Nicoletta Colombo, MD, PhD, from the University of Milan-Bicocca, Italy.
“Overall, data from KEYNOTE-826 suggest that pembrolizumab plus platinum-based chemotherapy with or without bevacizumab may be a new first-line standard of care,” she said in a late-breaking oral abstract presentation. The study was also simultaneously published online in The New England Journal of Medicine.
Since 2014, the standard of care for treating patients with recurrent, persistent, or metastatic cervical cancer has been chemotherapy with a platinum compound, paclitaxel, plus bevacizumab, based on the results of the GOG 240 study.
Immunotherapy with PD-1 inhibitors have shown efficacy as monotherapy in second- or later-line therapy for women with cervical cancer, but until now no data about the addition of these agents to chemotherapy were available, Dr. Colombo noted.
Dr. Mirza noted that there is sound rationale for using checkpoint inhibitors targeted against PD-1 in patients with cervical cancer, because PD-L1 has been shown to be a consistent biomarker for infection of the cervix with human papillomavirus (HPV), which is responsible for more than 90% of cervical cancers.
“PD-L1 is significantly upregulated in cervical cancer and detectable by immunohistochemistry,” he said. “PD-L1 expression reduces the immune response since it is able to bind to PD-1 on T-cell lymphocytes, thereby inhibiting their function. These findings suggest that targeting the PD-1/PD-L1 pathway may be therapeutically effective and should be considered in the treatment of cervical cancer.”
KEYNOTE-826 details
This was a double-blind trial conducted in 617 patients stratified by metastatic disease status at diagnosis; PD-L1 combined positive score (CPS) either < 1, 1 to < 10, or ≥ 10. They were randomized in a 1:1 ratio to receive pembrolizumab 200 mg or placebo every 3 weeks for up to 35 cycles plus platinum-based chemotherapy, with bevacizumab added at the investigator’s discretion.
The dual primary endpoints of progression-free survival (PFS) and overall survival (OS) were each tested sequentially in patients with a PD-L1 CPS ≥ 1 in both the intention-to-treat (ITT) or “all-comers” population, and in patients with a PD-L1 CPS ≥ 10.
Patient characteristics were generally well balanced between the treatment groups, except for a slightly higher proportion of patients with squamous cell histology in the pembrolizumab versus the placebo group (76.3% vs 68.3%).
PFS and OS results
The addition of pembrolizumab was associated with improved PFS across most protocol-specified subgroups, Dr. Colombo and colleagues noted.
After a median follow-up of 22 months, the 12-month PFS rate in the biomarker-selected population (all patients with a PD-L1 CPS ≥ 1) was 45.5% for patients in the pembrolizumab group versus 34.1% in the placebo group. This translated into a hazard ratio (HR) for progression on pembrolizumab of 0.62 (P < .001).
The respective PFS rates in the ITT population were 44.7% and 33.5%, with an HR for progression of 0.65 (P < .001) with the checkpoint inhibitor.
In patients with PD-L1 CPS ≥ 10, the respective rates of PFS and the HR were 44.6%, 33.5%, and 0.58 (P < .001).
OS rates were also significantly improved, he noted.
The 12-month and 24-month OS rates in all patients with PD-L1 CPS ≥ 1 were 75.3% and 53%, respectively, for patients assigned to pembrolizumab versus 63.1% and 41.7% in patients assigned to placebo, translating to an HR for death with pembrolizumab in this group of 0.64 (P < .001).
In the all-comers (ITT) population, respective 12- and 24-month OS rates were 74.8% and 50.4% with pembrolizumab versus 63.6% and 40.4% with placebo. This difference translated into an HR for death with anti-PD-1 of 0.67 (P < .001).
Among patients with the higher PD-L1 levels (≥ CPS 10), the respective OS rates were 75.7% and 54.4% with pembrolizumab versus 61.5% and 44.6% with placebo (HR 0.61, P < .001).
Dr. Mirza emphasized that “we did not see any efficacy of pembrolizumab in the biomarker-negative population,” with an HR for PFS of 0.94 and HR for OS of 1.0 in this subgroup.
The most common grade ≥ 3 adverse events were anemia, which occurred in 30.3% of patients assigned to pembrolizumab compared with 26.9% in the placebo group, and neutropenias, which occurred in 12.4% and 9.7% of patients, respectively. One patient in the pembrolizumab group died from an immune-related event, encephalitis.
Despite his enthusiasm for the regimen, Dr. Mirza tempered it by pointing out that there was an imbalance in the sample sizes regarding histology, and a potential bias introduced by the failure to stratify by tumor histology.
He noted that in other studies checkpoint inhibitors have had only modest activity against adenocarcinomas, which were more frequent in the placebo group in KEYNOTE-826, resulting in a potential positive bias in favor of pembrolizumab.

Adjuvant pembro success in early melanoma raises questions
However, the results raise many questions, says an expert invited to discuss the new data.
Adjuvant pembrolizumab is already approved in the United States for use in patients with melanoma with lymph node involvement following complete resection, having been shown to prolong both recurrence-free and distant metastasis-free survival (DMFS) in stage 3 melanoma.
This latest trial involved patients with slightly earlier disease, those with resected stage 2B and 2C melanoma. These patients are at “high risk” of disease recurrence and have similar outcomes to stage 3A and 3B melanoma patients, explained study presenter Jason J. Luke, MD, director of the Cancer Immunotherapeutics Center at UPMC Hillman Cancer Center, Pittsburgh.
Results from the KEYNOTE-716 trial showed that adjuvant pembrolizumab is also beneficial in this earlier stage disease: it improved recurrence-free survival (RFS) by 35% and improved distant metastasis-free survival by 40% compared with placebo.
Adjuvant pembrolizumab is an “effective treatment option with a favorable benefit-risk profile for patients with high-risk stage 2 melanoma,” Dr. Luke concluded.
The manufacturer, Merck, has said that these new results have already been accepted for priority review by the U.S. Food and Drug Administration, making it likely that the indication will be extended to include patients with earlier disease.
Dr. Luke presented the results at the European Society of Medical Oncology 2021 annual meeting.
Invited discussant Omid Hamid, MD, chief of research/immuno-oncology, the Angeles Clinic and Research Institute, a Cedars-Sinai Affiliate, Los Angeles, said that Dr. Luke’s presentation was “amazing.”
However, these new results have “sabotaged how we think about how we treat our patients and how we’re going to think about what we do in the future.”
Dr. Hamid noted that the incidence of stage 2B and 2C melanoma is “equal” to that of stage 3 disease, “so with a proposed approval” of pembrolizumab in this earlier setting, “we will have a lot more patients” to treat earlier in their disease course.
Of course, this raises the inevitable question of how to treat these patients when they relapse, and how to treat these patients in the metastatic setting “having already exhausted single-agent PD-1 therapy,” he commented.
Dr. Hamid said that the current results also reveal the “current problem” with adjuvant therapy, which is that “we don’t know who benefits,” and there is a subset patients who “never recur” even if they are untreated.
So the questions are: “How come all get treated? What about the risks of toxicity? The costs? And where do we fit these patients into clinic?”
As with so many presentations of immunotherapy trial data, the need for biomarkers was raised, with Dr. Hamid emphasizing the need for predictive biomarkers that could exclude patients, and save them from toxicity.
He noted that there were data with another checkpoint inhibitor, nivolumab (Opdivo), in the adjuvant setting (from the CheckMate 238 trial) that suggested higher tumor mutation burden and tumor interferon-gamma levels could play a role, and he hopes that similar data may be available from this latest trial.
Also, there are ongoing and upcoming trials in patients with stage 2B and 2C melanoma that may answer some of the outstanding questions, including a study of neoadjuvant PD-1 blockade before resection, and the DETECTION trial, which is exploring circulating tumor DNA-guided therapy postsurgery.
Then there is the NivoMela trial that will look at nivolumab in stage 2A as well as 2B and 2C disease, while the REFINE trial will assess whether giving immunotherapy less often to patients with advanced cancer, including those with melanoma, results in fewer side effects while continuing to be effective.
The current results also raise the question of whether to go “earlier and earlier” with adjuvant immunotherapy into “poor risk” stage 1 melanoma, which is already being tried in the United States, although there is “no clear understanding of what to do for those patients.”
Overall, Dr. Hamid said that the results of KEYNOTE-716 have “created more questions than answers,” including its impact on the inclusion criteria for phase 3/4 clinical trials, “which now exclude patients who have received adjuvant therapy within 6 months.”
“That will have to change,” he suggested.
Some of the questions raised by Dr. Hamid were discussed on social media, sparking a lively Twitter debate on how best to take the results forward and into the clinic.
Florentia Dimitriou, MD, a dermatology consultant in the Skin Cancer Clinic, University Hospital Zurich, Switzerland, said the data were “great” but she was “still unclear” over who needs adjuvant immunotherapy in this setting.
She also emphasized that, for her, the greater RFS benefit seen in T3b than in T4b disease “doesn’t make sense,” and she also highlighted the finding of long-term toxicity in approximately 18% of patients.
Dr. Luke replied that he agrees that the T3b/T4b results are puzzling but he said the event rate was “low” and the data are “immature,” and that he hopes to have “more info soon.”
He acknowledged that around 18% of patients taking pembrolizumab went on to receive hormone therapy for adverse events, including 13.9% due to hypothyroidism, and others including hypophysitis, adrenal sufficiency, and type 1 diabetes. However, he also pointed out that about 5% of patients in this study had background thyroid issues. The risks and benefits of treatment need to be discussed with patients, he added.
Over a series of tweets, Rebecca J. Lee, PhD, NIHR clinical lecturer in medical oncology at the University of Manchester, United Kingdom, said, “we need to know more” about the distant metastasis-free survival results, and that results for overall survival are “really” needed.
She also emphasized the need for biomarkers to identify those patients who are likely to benefit, and whether benefit can be upfront or early on in treatment. Dr. Lee added that, as endocrine thyroid toxicity occurs after a median of 3.3 months, “pretreatment biomarkers will be more important than on-treatment biomarkers in this setting.”
Details of the results in earlier stage disease
The KEYNOTE-716 trial enrolled patients with newly diagnosed, resected, high-risk stage 2 melanoma aged ≥ 12 years and a good performance status. The majority (~64%) had stage 2B melanoma, and the rest had stage 2C. T3b disease was present in 41% of patients, 23% had T4a disease, and 35% had T4b disease.
Patients were randomized to receive pembrolizumab or placebo.
In a subsequent part of the study, patients with recurrence will be unblended, with either crossover from the placebo to active treatment group or rechallenge with pembrolizumab for up to 2 years.
Presenting the first part, Dr. Luke said that, of 487 patients assigned to pembrolizumab, 483 started treatment, of whom 206 have completed treatment, 133 are still on therapy, and 144 have discontinued.
In the placebo group, 489 patients were assigned and 486 began treatment. Of those, 229 completed treatment, 152 are still ongoing, and 105 discontinued.
The two groups were well balanced in terms of baseline characteristics. The median age was approximately 60 years, with only one patient enrolled who was aged 12-17 years.
At 12 months, the study met its primary endpoint.
Relapse-fee survival was 90.5% in patients treated with pembrolizumab versus 83.1% in the placebo group, at a hazard ratio for recurrence of 0.65 (P = .00658).
“Despite this trial hitting this primary endpoint very early, there are a number of patients who are censored later in the curves,” Dr. Luke said, adding that “we will continue to see these data mature.”
“In fact, it’s our full expectation that curves will continue to separate over time.”
When looking at key subgroups, Dr. Luke showed that the results favored pembrolizumab when stratifying patients by age, gender, race, and performance status.
Interestingly, patients with T3b disease did a lot better on pembrolizumab compared with those who had T4b disease, at a hazard ratio for recurrence of 0.44 versus 0.94.
Data on recurrence patterns revealed that 11.1% of patients taking pembrolizumab had an event, with 6.4% experiencing skin and/or lymph node regional recurrence and 4.7% distant recurrence.
In the placebo group, 16.8% of patients had a recurrence event, with 8.4% having a loco-regional recurrence and 7.8% a distant recurrence.
Dr. Luke explained that this equates to an approximate 40% reduction in distant recurrence with pembrolizumab over placebo.
Finally, the researchers examined change in global health status on the EORTC QLQ-C30 quality of life score. Examining mean change over time, they found that there were no clinically meaningful changes, and the scores in the pembrolizumab and placebo groups tracked each other during the course of follow-up.
Quality of life was, therefore, “only minimally changed,” Dr. Luke said.
The study was funded by MSD. Dr. Luke and Dr. Hamid have declared relationships with multiple companies.

However, the results raise many questions, says an expert invited to discuss the new data.
Adjuvant pembrolizumab is already approved in the United States for use in patients with melanoma with lymph node involvement following complete resection, having been shown to prolong both recurrence-free and distant metastasis-free survival (DMFS) in stage 3 melanoma.
This latest trial involved patients with slightly earlier disease, those with resected stage 2B and 2C melanoma. These patients are at “high risk” of disease recurrence and have similar outcomes to stage 3A and 3B melanoma patients, explained study presenter Jason J. Luke, MD, director of the Cancer Immunotherapeutics Center at UPMC Hillman Cancer Center, Pittsburgh.
Results from the KEYNOTE-716 trial showed that adjuvant pembrolizumab is also beneficial in this earlier stage disease: it improved recurrence-free survival (RFS) by 35% and improved distant metastasis-free survival by 40% compared with placebo.
Adjuvant pembrolizumab is an “effective treatment option with a favorable benefit-risk profile for patients with high-risk stage 2 melanoma,” Dr. Luke concluded.
The manufacturer, Merck, has said that these new results have already been accepted for priority review by the U.S. Food and Drug Administration, making it likely that the indication will be extended to include patients with earlier disease.
Dr. Luke presented the results at the European Society of Medical Oncology 2021 annual meeting.
Invited discussant Omid Hamid, MD, chief of research/immuno-oncology, the Angeles Clinic and Research Institute, a Cedars-Sinai Affiliate, Los Angeles, said that Dr. Luke’s presentation was “amazing.”
However, these new results have “sabotaged how we think about how we treat our patients and how we’re going to think about what we do in the future.”
Dr. Hamid noted that the incidence of stage 2B and 2C melanoma is “equal” to that of stage 3 disease, “so with a proposed approval” of pembrolizumab in this earlier setting, “we will have a lot more patients” to treat earlier in their disease course.
