Fewer than half of health care providers offer routine contraception along with emergency contraception
Key clinical point: In 2019, 41% of health care providers prescribed regular contraception at the same time as emergency contraception; this percentage was an increase from 2013-2014, but falls short of the US Selected Practice Recommendations for Contraceptive Use, first released in 2013.
Major finding: Health care providers in 2019 were more likely than health care providers in 2013 and 2014 to prescribe or provide contraception when providing emergency contraception (adjusted prevalence ratio 1.26) and to provide a copper intrauterine device (adjusted prevalence ratio 3.87). A total of 41% frequently provided or prescribed regular contraception at the time of providing emergency contraceptive pills (ECP), 16% of providers in 2019 frequently provided an advance prescription for ECPs, 8% provided a copper intrauterine device as emergency contraception, and 7% provided an advance supply of ECPs.
Study details: The data come from two cross-sectional surveys mailed to office-based physicians and public-sector health care providers in the United States in 2013-14 (2,060 respondents) and 2019 (1,420 respondents).
Disclosures: The study was published on behalf of the Jacobs Institute of Women’s Health. The researchers had no financial conflicts to disclose.

LARCs prompt increase in body mass index among adolescents
Key clinical point: Use of progestin-releasing long-acting reversible contraceptives (LARC) was linked to weight gain in nulliparous adolescents aged 14-19 years; 25% of the study population was obese, and significant interaction effect (P = .017) showed a greater increase in BMI in this subset of participants who used an LARC compared to a copper intrauterine device (IUD).
Major finding: The mean change in body mass index among teen girls who used LARC was an increase of 0.73 kg/m2; BMI increases averaged 0.92 kg/m2 for those who used an etornogestrel subdermal implant plus levonorgestrel intrauterine device (LNG-IUD) and 0.37 kg/m2 in those who used a copper IUD.
Study details: The data come from a retrospective cohort study of 196 adolescents aged 14-19 years who underwent placement of long-acting reversible contraceptive devices.
Disclosures: The study received no outside funding. The researchers had no financial conflicts to disclose.

Counseling promotes contraception in hospitalized adolescents
Key clinical point: Among young women, the average Pregnancy Risk Index (PRI) was 4.75; individuals using teratogenic medication had the lowest PRI (0.32); 88% of these individuals used reversible contraception and 31% used long-acting reversible contraception.
Major finding: Approximately 73% of sexually active young women received contraceptive counseling, which was associated with a significantly increased use of reversible and dual contraception, but not long-acting reversible contraception. At last reported vaginal sex, 65% reported using condoms, 49% reported using reversible contraception, and 12% reported using long-acting reversible contraception.
Study details: The data come from a cross-sectional survey of 177 hospitalized females aged 14 to 21 years at two academic medical centers; the surveys assessed sexual health behaviors, contraceptive use, contraceptive counseling, and pregnancy complications. Researchers calculated the Pregnancy Risk Index (the number per 100 individuals who will become pregnant in the next year).

Levonorgestrel expulsion rates are similar for contraception or heavy bleeding
Key clinical point: Expulsion rates were similar for women using a 52 mg levonorgestrel intrauterine system for heavy menstrual bleeding and those who used it for contraception; a history of cesarean delivery increased the risk of expulsion in both groups.
Major finding: Expulsion of the device occurred in 548 of the women with heavy menstrual bleeding (5.6%) and 315 of the women using the device for contraception (5.6%). The odds ratio for expulsion for women with a history of cesarean delivery in either group was 1.93.
Study details: The data come from an audit of 548 women who used a 52 mg levonorgestrel intrauterine system to manage heavy menstrual bleeding and 5,655 who used it for contraception.

Contraception prescription patterns vary by specialty and geography
Key clinical point: The contraception workforce in the United States varies by geography, provider specialty, and Medicaid acceptance, and gaps remain in the provision of IUDs and implants.
Major finding: Approximately 73% of obgyns and nurse midwives prescribed the pill, patch, or ring, compared to 51% of family medicine physicians, 32% of pediatricians, and 20% of internal medicine physicians. A majority of obgyns provided contraception to Medicaid patients, ranging from 84% in the District of Columbia to 100% in North Dakota.
Study details: The data come from an observational study of the contraception workforce in the United States. A team of researchers created a comprehensive database of the workforce in the United States that provides six contraception types: intrauterine device (IUD), implant, shot (depot medroxyprogesterone acetate, or DMPA), oral contraception, hormonal patch, and vaginal ring.
Disclosures: The study was funded by a private foundation that wishes to remain anonymous. The researchers had no financial conflicts to disclose.

FDA panel backs Pfizer's COVID booster for 65 and older, those at high risk
An expert panel that advises the Food and Drug Administration on its regulatory decisions voted Sept. 17 against recommending third doses of Pfizer’s COVID-19 vaccine for younger Americans.
But they didn’t kill the idea of booster shots completely.
In a dramatic, last-minute pivot, the 18 members of the FDA’s Vaccines and Related Biological Products Advisory Committee unanimously voted to recommend the FDA make boosters available for seniors and others at high risk of severe outcomes from COVID-19, including health care workers.
The 16-2 vote was a rebuttal to Pfizer’s initial request. The company had asked the FDA to allow it to offer third doses to all Americans over the age of 16 at least six months after their second shot.
The company requested an amendment to the full approval the FDA granted in August. That is the typical way boosters are authorized in the U.S., but it requires a higher bar of evidence and more regulatory scrutiny than the agency had been able to give since Pfizer filed for the change just days after its vaccine was granted full approval.
The committee’s actions were also a rebuff to the Biden administration, which announced before the FDA approved them that boosters would be rolled out to the general public Sept. 20. The announcement triggered the resignations of two of the agency’s top vaccine reviewers, who both participated in the Sept. 17 meeting.
After initially voting against Pfizer’s request to amend its license, the committee then worked on the fly with FDA officials to craft a strategy that would allow third doses to be offered under an emergency use authorization (EUA).
An EUA requires a lower standard of evidence and is more specific. It will restrict third doses to a more defined population than a change to the license would. It will also require Pfizer to continue to monitor the safety of third doses as they begin to be administered.
“This should demonstrate to the public that the members of this committee are independent of the FDA and that we do, in fact, bring our voices to the table when we are asked to serve on this committee,” said Archana Chattergee, MD, a pediatric infectious disease specialist who is dean of the Chicago Medical School at Rosalind Franklin University in Illinois.
The FDA doesn’t have to follow the committee’s recommendation, but almost certainly will, though regulators said they may still make some changes.
“We are not bound at FDA by your vote, we can tweak this,” said Peter Marks, MD, director of the Center for Biologics Evaluation and Research at the FDA. Dr. Marks participated in the meeting and helped to draft the revised proposal.
If the FDA issues the recommended EUA, a council of independent advisors to the CDC will make specific recommendations about how the third doses should be given. After the CDC director weighs in, boosters will begin rolling out to the public.
Moderna submitted data to the FDA on Sept. 1 in support of adding a booster dose to its regimen. The agency has not yet scheduled a public review of that data.
The Biden administration is prepared to administer shots as soon as they get the green light, Surgeon General Vivek Murthy, MD, said at a White House briefing earlier Sept. 17.
"This process is consistent with what we outlined in August where our goals were to stay ahead of the virus," Dr. Murthy said. "Our goal then and now is to protect the health and well-being of the public. As soon as the FDA and CDC complete their evaluations, we will be ready to move forward accordingly."
He added, "We've used this time since our August announcement to communicate and coordinate with pharmacy partners, nursing homes, states, and localities."
White House COVID-19 Response Coordinator Jeff Zients said vaccine supply is "in good shape for all Americans to get boosters as recommended."
Taking cues from Israel
In considering Pfizer’s original request, the committee overwhelmingly felt that they didn’t have enough information to say that the benefits of an additional dose of vaccine in 16- and 17-year-olds would outweigh its risk. Teens have the highest risk of rare heart inflammation after vaccination, a side effect known as myocarditis. It is not known how the vaccines are causing these cases of heart swelling. Most who have been diagnosed with the condition have recovered, though some have needed hospital care.
Pfizer didn’t include 16- and 17-year-olds in its studies of boosters, which included about 300 people between the ages of 18 and 55. The company acknowledged that gap in its data but pointed to FDA guidance that said evidence from adults could be extrapolated to teens.
“We don’t know that much about risks,” said committee member Eric Rubin, MD, who is editor-in-chief of the New England Journal of Medicine.
Much of the data on the potential benefits and harms of third Pfizer doses comes from Israel, which first began rolling out boosters to older adults in July.
In a highly anticipated presentation, Sharon Alroy-Preis, Israel’s director of public health services, joined the meeting to describe Israel’s experience with boosters.
Israel began to see a third surge of COVID-19 cases in December.
“This was after having two waves and two lockdowns,” Ms. Alroy-Preis said. By the third surge, she said, Israelis were tired.
“We decided on a lockdown, but the compliance of the public wasn’t as it was in the previous two waves,” she said.
Then the vaccine arrived. Israel started vaccinations as soon as the FDA approved it, and they quickly vaccinated a high percentage of their population, about 3 months faster than the rest of the world.
All vaccinations are reported and tracked by the Ministry of Health, so the country is able to keep close tabs on how well the shots are working.
As vaccines rolled out, cases fell dramatically. The pandemic seemed to be behind them. Delta arrived in March. By June, their cases were doubling every 10 days, despite about 80% of their most vulnerable adults being fully vaccinated, she said.
Most concerning was that about 60% of severe cases were breakthrough cases in fully vaccinated individuals.
“We had to stop and figure out, was this a Delta issue,” she said. “Or was this a waning immunity issue.”
“We had some clue that it might not be the Delta variant, at least not alone,” she said.
People who had originally been first in line for the vaccines, seniors and health care workers, were having the highest rates of breakthrough infections. People further away from their second dose were more likely to get a breakthrough infection.
Ms. Alroy-Preis said that if they had not started booster doses in July, their hospitals would have been overwhelmed. They had projected that they would have 2,000 cases in the hospital each day.
Boosters have helped to flatten the curve, though they are still seeing a significant number of infections.
Data from Israel presented at the meeting show boosters are largely safe and effective at reducing severe outcomes in seniors. Israeli experience also showed that third doses, which generate very high levels of neutralizing antibodies—the first and fastest line of the body’s immune defense - -may also slow transmission of the virus.
Key differences in the U.S.
The benefit of slowing down the explosive spread of a highly contagious virus was tantalizing, but many members noted that circumstances in Israel are very different than in the United States. Israel went into its current Delta surge already having high levels of vaccination in its population. They also relied on the Pfizer vaccine almost exclusively for their campaign.
The United States used a different mix of vaccines – Pfizer, Moderna, and Johnson & Johnson -- and doesn’t have the same high level of vaccination coverage of its population.
In the United States, transmission is mainly being driven by unvaccinated people, Dr. Rubin noted.
“That really means the primary benefit is going to be in reducing disease,” he said, “And we know the people who are going to benefit from that … and those are the kinds of people the FDA has already approved a third dose for,” he said, referring to those with underlying health conditions.
But Israel only began vaccinating younger people a few weeks ago. Most are still within a window where rare risks like myocarditis could appear, Rubin noted.
He and other members of the committee said they wished they had more information about the safety of third doses in younger adults.
“We don’t have that right now, and I don’t think I would be comfortable giving it to a 16-year-old,” he said.
At the same time, the primary benefit for third doses would be in preventing severe disease, and overall, data from the United States and other countries show that two doses of the vaccines remain highly effective at preventing hospitalization and death.
Asked why Israel began to see more severe cases in fully vaccinated people, the CDC’s Sara Oliver, MD, a disease detective with the CDC, said it was probably due to a mix of factors including the fact that Israel defines severe cases a little differently.
In the United States, a severe case is generally a person who has to be hospitalized or who has died from the infection. In Israel, a person with a severe case is someone who has an elevated respiratory rate and someone who has a blood oxygen level less than 94%. In the United States, that kind of patient wouldn’t necessarily be hospitalized.
In the end, one of the two committee members who wanted full approval for Pfizer’s third doses said he was satisfied with the outcome.
Mark Sawyer, MD, a professor of pediatrics and infectious disease at the University of California at San Diego, said he voted yes on the first question because he thought full approval was the best way to give doctors the flexibility to prescribe the shots to vulnerable individuals.
“I’m really glad we authorized a vaccine for a third dose, and I plan to go out and get my vaccine this afternoon,” Dr. Sawyer said, noting that he was at high risk as a health care provider.

An expert panel that advises the Food and Drug Administration on its regulatory decisions voted Sept. 17 against recommending third doses of Pfizer’s COVID-19 vaccine for younger Americans.
But they didn’t kill the idea of booster shots completely.
In a dramatic, last-minute pivot, the 18 members of the FDA’s Vaccines and Related Biological Products Advisory Committee unanimously voted to recommend the FDA make boosters available for seniors and others at high risk of severe outcomes from COVID-19, including health care workers.
The 16-2 vote was a rebuttal to Pfizer’s initial request. The company had asked the FDA to allow it to offer third doses to all Americans over the age of 16 at least six months after their second shot.
The company requested an amendment to the full approval the FDA granted in August. That is the typical way boosters are authorized in the U.S., but it requires a higher bar of evidence and more regulatory scrutiny than the agency had been able to give since Pfizer filed for the change just days after its vaccine was granted full approval.
The committee’s actions were also a rebuff to the Biden administration, which announced before the FDA approved them that boosters would be rolled out to the general public Sept. 20. The announcement triggered the resignations of two of the agency’s top vaccine reviewers, who both participated in the Sept. 17 meeting.
After initially voting against Pfizer’s request to amend its license, the committee then worked on the fly with FDA officials to craft a strategy that would allow third doses to be offered under an emergency use authorization (EUA).
An EUA requires a lower standard of evidence and is more specific. It will restrict third doses to a more defined population than a change to the license would. It will also require Pfizer to continue to monitor the safety of third doses as they begin to be administered.
“This should demonstrate to the public that the members of this committee are independent of the FDA and that we do, in fact, bring our voices to the table when we are asked to serve on this committee,” said Archana Chattergee, MD, a pediatric infectious disease specialist who is dean of the Chicago Medical School at Rosalind Franklin University in Illinois.
The FDA doesn’t have to follow the committee’s recommendation, but almost certainly will, though regulators said they may still make some changes.
“We are not bound at FDA by your vote, we can tweak this,” said Peter Marks, MD, director of the Center for Biologics Evaluation and Research at the FDA. Dr. Marks participated in the meeting and helped to draft the revised proposal.
If the FDA issues the recommended EUA, a council of independent advisors to the CDC will make specific recommendations about how the third doses should be given. After the CDC director weighs in, boosters will begin rolling out to the public.
Moderna submitted data to the FDA on Sept. 1 in support of adding a booster dose to its regimen. The agency has not yet scheduled a public review of that data.
The Biden administration is prepared to administer shots as soon as they get the green light, Surgeon General Vivek Murthy, MD, said at a White House briefing earlier Sept. 17.
"This process is consistent with what we outlined in August where our goals were to stay ahead of the virus," Dr. Murthy said. "Our goal then and now is to protect the health and well-being of the public. As soon as the FDA and CDC complete their evaluations, we will be ready to move forward accordingly."
He added, "We've used this time since our August announcement to communicate and coordinate with pharmacy partners, nursing homes, states, and localities."
White House COVID-19 Response Coordinator Jeff Zients said vaccine supply is "in good shape for all Americans to get boosters as recommended."
Taking cues from Israel
In considering Pfizer’s original request, the committee overwhelmingly felt that they didn’t have enough information to say that the benefits of an additional dose of vaccine in 16- and 17-year-olds would outweigh its risk. Teens have the highest risk of rare heart inflammation after vaccination, a side effect known as myocarditis. It is not known how the vaccines are causing these cases of heart swelling. Most who have been diagnosed with the condition have recovered, though some have needed hospital care.
Pfizer didn’t include 16- and 17-year-olds in its studies of boosters, which included about 300 people between the ages of 18 and 55. The company acknowledged that gap in its data but pointed to FDA guidance that said evidence from adults could be extrapolated to teens.
“We don’t know that much about risks,” said committee member Eric Rubin, MD, who is editor-in-chief of the New England Journal of Medicine.
Much of the data on the potential benefits and harms of third Pfizer doses comes from Israel, which first began rolling out boosters to older adults in July.
In a highly anticipated presentation, Sharon Alroy-Preis, Israel’s director of public health services, joined the meeting to describe Israel’s experience with boosters.
Israel began to see a third surge of COVID-19 cases in December.
“This was after having two waves and two lockdowns,” Ms. Alroy-Preis said. By the third surge, she said, Israelis were tired.
“We decided on a lockdown, but the compliance of the public wasn’t as it was in the previous two waves,” she said.

‘Urgent’ need to understand immunotherapy de-escalation in NSCLC
However, the research to date does not provide a clear picture of which patients will achieve this “exceptional and durable response” and at which point patients can safely reduce or withdraw from treatment, according to Yasushi Goto, MD, PhD, a staff doctor in the Department of Thoracic Oncology, National Cancer Center Hospital, Tokyo.
Dr. Goto presented the latest evidence and explored the current unknowns surrounding immunotherapy de-escalation in NSCLC in a session this week at the virtual World Conference on Lung Cancer.
In addition to a toxicity and quality-of-life benefit for patients, immunotherapy de-escalation could have a significant impact on the costs of care, Dr. Goto stressed. The rising cost of new cancer treatments represents a “crisis” in terms of the affordability of health care, he said, and reducing these costs represents an “urgent global issue.”
Evidence on discontinuing treatment
Dr. Goto kicked off the session by emphasizing how drastically immunotherapy has enhanced outcomes for patients with NSCLC and other cancers.
This success has brought a pressing clinical question to the forefront: How long should we treat patients with immunotherapy?
The question arose over 10 years ago when ipilimumab (Yervoy) was granted FDA approval for patients with metastatic melanoma, but only for a total of four doses because of the drug’s toxicity.
“However, some patients had very lasting efficacy with the drug, even after discontinuation,” Dr. Goto said, which raised the exciting prospect that patients could achieve a functional cure with immunotherapy.
Evidence highlighting this lasting effect among patients with NSCLC soon emerged as well. A 2015 study, for instance, indicated that, despite toxicities, 50% of patients receiving nivolumab (Opdivo) continued to have a treatment effect more than 9 months after their last dose.
A 2021 analysis of patients receiving pembrolizumab (Keytruda) found that 48% of patients were disease-free after 5 years, despite having discontinued treatment after 2 years.
These investigators also found that toxicities accumulated over time – new grade greater than or equal to three toxicities occurred in 10% of patients every 6 months – which makes it particularly important to consider limiting the duration of therapy, Dr. Goto noted.
Only one randomized study to date – the CheckMate 153 trial – has explicitly explored outcomes associated with discontinuing immunotherapy in patients with NSCLC. In this study, patients still receiving nivolumab after 1 year were randomized to continue or stop therapy. Both median progression-free survival and overall survival were significantly longer in patients who continued therapy versus those who stopped at 1 year.
However, Dr. Goto noted that limitations in the study design, including the fact that many patients were censored at an early stage, made the results “nonconfirmatory” and he would like to see more data.
The role of re-treatment
Finding the optimal time to discontinue treatment is critical but even if patients stop treatment before they achieve long-lasting benefits, they can still be retreated successfully.
Two recent studies examined the potential benefits of re-treatment. In the 2021 KEYNOTE-010 analysis, 21 patients received a second course of pembrolizumab, at a response rate of 53% and a disease control rate of 81%.
In another recent study, investigators found that among 78 patients with melanoma who had discontinued either nivolumab or pembrolizumab and were re-treated after disease progression, 15% (5 of 34) receiving a single anti-PD-1 agent responded to retreatment and 25% (11 of 44) escalated to nivolumab plus ipilimumab exhibited a response.
Dr. Goto noted that there are also ongoing randomized studies examining the optimal duration of immunotherapy in advanced melanoma. One that he is involved in, the SAVE study, is enrolling patients with advanced NSCLC who have responded to anti-PD-1 agents for over a year and will compare overall survival in those who stop therapy versus those who continue. In addition, given the “growing importance” of biomarkers as a prediction tool, Dr. Goto plans to integrate circulating tumor DNA testing to help identify patients more likely to benefit from therapy discontinuation.
If successful, such approaches could “disruptively decrease prescribing costs,” by lowering doses or dose frequency, shortening the treatment duration, or by substituting therapies with fewer adverse effects, Dr. Goto said.
Discussing de-escalation in practice
During the discussion period after his talk, session co-chair Loretta Erhunmwunsee, MD, City of Hope Comprehensive Cancer Center, Duarte, California, asked Dr. Goto what his current practice is in regard to de-escalation.
He replied that, in Japan, physicians are allowed to continue immunotherapy beyond 2 years, but “many patients stop their immune checkpoint inhibitor due to toxicity,” even if it is minor.
Exploring evidence surrounding the optimal duration of therapy, session cochair Bishal Gyawali, MD, PhD, Queen’s University, Kingston, Canada, pointed to collaborative studies in colon cancer that looked at chemotherapy duration, for example looking at 3 versus 6 months of treatment.
Dr. Gyawali wondered whether the same could be achieved in lung cancer to test the non-inferiority of shorter duration of immunotherapy versus continuing treatment until disease progression.
Dr. Goto noted that the biggest difference in the current context of NSCLC is the toxicity incurred by both the adjuvant chemotherapy and the immunotherapy, making the overall benefit to the patient “very difficult to show.” Consequently, patients may not be willing to join a randomized trial in which they could experience additional toxicity for uncertain benefit.
City of Hope oncologist H. Jack West, MD, who presented at the session, said he would “love to see more trials looking at de-escalation and seeing whether we do just as well on efficacy with lower toxicity and lower costs.”
Instead, “we are seeing reports of the fourth entrant into the field that just recapitulates things we already know,” which is “terribly disappointing.”
“I really wish we could vote with our feet more and not participate in trials that are completely redundant compared to what we’ve had for years already,” Dr. West said.
No funding for this study was declared. Dr. Goto disclosed relationships with AbbVie, AstraZeneca, Boehringer Ingelheim, Bristol-Myers Squibb, Chugai, Daiichi Sankyo, Eli Lilly, GlaxoSmithKline, Guardant Health, Illumina, Kyorin, MSD, Novartis, Ono Pharmaceutical, Pfizer, Shionogi Pharma, and Taiho Pharmaceutical. Dr. West disclosed relationships with AstraZeneca, EQRx, Genentech/Roche, Merck, Mirati, and Regeneron and is a regular contributor to Medscape Oncology.

Dr. Goto noted that the biggest difference in the current context of NSCLC is the toxicity incurred by both the adjuvant chemotherapy and the immunotherapy, making the overall benefit to the patient “very difficult to show.” Consequently, patients may not be willing to join a randomized trial in which they could experience additional toxicity for uncertain benefit.
City of Hope oncologist H. Jack West, MD, who presented at the session, said he would “love to see more trials looking at de-escalation and seeing whether we do just as well on efficacy with lower toxicity and lower costs.”
Instead, “we are seeing reports of the fourth entrant into the field that just recapitulates things we already know,” which is “terribly disappointing.”
“I really wish we could vote with our feet more and not participate in trials that are completely redundant compared to what we’ve had for years already,” Dr. West said.
No funding for this study was declared. Dr. Goto disclosed relationships with AbbVie, AstraZeneca, Boehringer Ingelheim, Bristol-Myers Squibb, Chugai, Daiichi Sankyo, Eli Lilly, GlaxoSmithKline, Guardant Health, Illumina, Kyorin, MSD, Novartis, Ono Pharmaceutical, Pfizer, Shionogi Pharma, and Taiho Pharmaceutical.

However, the research to date does not provide a clear picture of which patients will achieve this “exceptional and durable response” and at which point patients can safely reduce or withdraw from treatment, according to Yasushi Goto, MD, PhD, a staff doctor in the Department of Thoracic Oncology, National Cancer Center Hospital, Tokyo.
Dr. Goto presented the latest evidence and explored the current unknowns surrounding immunotherapy de-escalation in NSCLC in a session this week at the virtual World Conference on Lung Cancer.
In addition to a toxicity and quality-of-life benefit for patients, immunotherapy de-escalation could have a significant impact on the costs of care, Dr. Goto stressed. The rising cost of new cancer treatments represents a “crisis” in terms of the affordability of health care, he said, and reducing these costs represents an “urgent global issue.”
Evidence on discontinuing treatment
Dr. Goto kicked off the session by emphasizing how drastically immunotherapy has enhanced outcomes for patients with NSCLC and other cancers.
This success has brought a pressing clinical question to the forefront: How long should we treat patients with immunotherapy?
The question arose over 10 years ago when ipilimumab (Yervoy) was granted FDA approval for patients with metastatic melanoma, but only for a total of four doses because of the drug’s toxicity.
“However, some patients had very lasting efficacy with the drug, even after discontinuation,” Dr. Goto said, which raised the exciting prospect that patients could achieve a functional cure with immunotherapy.
Evidence highlighting this lasting effect among patients with NSCLC soon emerged as well. A 2015 study, for instance, indicated that, despite toxicities, 50% of patients receiving nivolumab (Opdivo) continued to have a treatment effect more than 9 months after their last dose.
A 2021 analysis of patients receiving pembrolizumab (Keytruda) found that 48% of patients were disease-free after 5 years, despite having discontinued treatment after 2 years.
These investigators also found that toxicities accumulated over time – new grade greater than or equal to three toxicities occurred in 10% of patients every 6 months – which makes it particularly important to consider limiting the duration of therapy, Dr. Goto noted.
Only one randomized study to date – the CheckMate 153 trial – has explicitly explored outcomes associated with discontinuing immunotherapy in patients with NSCLC. In this study, patients still receiving nivolumab after 1 year were randomized to continue or stop therapy. Both median progression-free survival and overall survival were significantly longer in patients who continued therapy versus those who stopped at 1 year.
However, Dr. Goto noted that limitations in the study design, including the fact that many patients were censored at an early stage, made the results “nonconfirmatory” and he would like to see more data.
The role of re-treatment
Finding the optimal time to discontinue treatment is critical but even if patients stop treatment before they achieve long-lasting benefits, they can still be retreated successfully.
Two recent studies examined the potential benefits of re-treatment. In the 2021 KEYNOTE-010 analysis, 21 patients received a second course of pembrolizumab, at a response rate of 53% and a disease control rate of 81%.
In another recent study, investigators found that among 78 patients with melanoma who had discontinued either nivolumab or pembrolizumab and were re-treated after disease progression, 15% (5 of 34) receiving a single anti-PD-1 agent responded to retreatment and 25% (11 of 44) escalated to nivolumab plus ipilimumab exhibited a response.
Dr. Goto noted that there are also ongoing randomized studies examining the optimal duration of immunotherapy in advanced melanoma. One that he is involved in, the SAVE study, is enrolling patients with advanced NSCLC who have responded to anti-PD-1 agents for over a year and will compare overall survival in those who stop therapy versus those who continue. In addition, given the “growing importance” of biomarkers as a prediction tool, Dr. Goto plans to integrate circulating tumor DNA testing to help identify patients more likely to benefit from therapy discontinuation.
If successful, such approaches could “disruptively decrease prescribing costs,” by lowering doses or dose frequency, shortening the treatment duration, or by substituting therapies with fewer adverse effects, Dr. Goto said.
Discussing de-escalation in practice
During the discussion period after his talk, session co-chair Loretta Erhunmwunsee, MD, City of Hope Comprehensive Cancer Center, Duarte, California, asked Dr. Goto what his current practice is in regard to de-escalation.
He replied that, in Japan, physicians are allowed to continue immunotherapy beyond 2 years, but “many patients stop their immune checkpoint inhibitor due to toxicity,” even if it is minor.
