Patients in their 90s with cancer tolerated immunotherapy well with few serious adverse effects, and they lived for an average of 1.6 years after treatment, a small new study within the US Department of Veterans Affairs (VA) health system reports.

Only 6.3% of 48 patients who were treated with immune checkpoint inhibitors experienced the most severe types of side effects – grade III/IV events – and a total of 27% had any adverse effects, according to the report, which was presented at the 2021 annual meeting of the Association of VA Hematology/Oncology (AVAHO) being held virtually and inperson in Denver Colorado, September 24 to September 26, 2021.

“Our project should help give confidence to oncologists treating the elderly,” said Andrew Joseph Benefield, MD, a hematology/oncology fellow at Wake Forest Baptist Medical Center, in an interview. “Immunotherapy can be given safely and likely effectively in select individuals over the age of 90 with good performance status.”

Benefield and colleagues launched their study to gain insight into a little-studied area: How does cancer treatment affects nonagenarians? “I think many oncologists have been in a situation where they encounter an individual over the age of 90 years who has a good performance status, and they've wondered if immunotherapy would be helpful and safe, particularly given our knowledge of waning immune strength as people age,” he said.

The researchers retrospectively tracked patients with cancer who were at least 90 years old from 2016 to 2017 and were treated with immune checkpoint inhibitors. Most were fit or fairly fit with Eastern Cooperative Oncology Group (ECOG) physical performance scales of 0 or 1 (n = 26), and nearly all had cancer in stage IV (n = 42). Melanoma was the most common type of cancer (n = 19), followed by non-small-cell lung cancer (n = 15). Patients were treated with an average of 12.2 cycles.

“In general, we saw that treatment was well-tolerated,” Dr. Benefield said. “We also noted that a trend toward better long-term survival outcomes in individuals with very good performance status at the start of treatment. We hope to parse this out more as we add more data to our data-set, as the numbers are still too small for confident direct comparison.”

Dr. Benefield said he has treated a limited number of patients in their 90s who were highly physical fit for their age and “very eager” to be treated. “They wanted to do anything they could to maintain their lifestyle,” he said. “In my experience, aggressive supportive care and close monitoring for developing toxicities has been most helpful.”

The researchers don’t know the causes of death of many of the patients, and it’s not clear how they fared in their final days. Still, Dr. Benefield said, “extending someone's life by more than 1 year with relatively low risk of adverse effects is reasonable.”

Oncologist Melisa Wong, MD, MAS, of the University of California, San Francisco, reviewed the study and said in an interview that it “a valuable description of outcomes for nonagenarians receiving immunotherapy in the VA healthcare system.” As she noted, “many other studies of immunotherapy among older adults focus on patients aged 65 or 70 and older while very few focus on octogenarians or nonagenarians.”

The findings suggest that “it is important to move beyond chronological age and assess patients’ physiologic age through a geriatric assessment,” she said. “Geriatric assessment-derived risk scores have been shown to predict chemotherapy toxicity for older adults and research to develop similar tools for immunotherapy are ongoing.”

However, she cautioned that older patients may become suffer so much from the most common side effect of immunotherapy -- fatigue – that “their independence is at stake.”

“Some of these patient choose to stop immunotherapy because the side effects aren’t worth it anymore,” she said. “The challenge for oncologists is not knowing in advance which patients will fall into each of these categories.”

She added that her geriatric oncology research focuses on improving risk stratification for older adults, such as those who are at least 70 with lung adenocarcinoma.

Oncologist Grant R. Williams, MD, MSPH, director of the Cancer & Aging Program at the University of Alabama at Birmingham, agreed in an interview that comprehensive geriatric assessments are important to guide treatment in the oldest adults. “In addition, it is important to elicit the goals of treatment as well,” he said. “For older adults that are fit or at least pre-frail and desire aggressive treatment, immunotherapy is a very reasonable approach, particularly when patients are closely monitored for side effects.”

Background

We sought to evaluate passive recruitment efforts of VA patients into a precision medicine research program. Access to clinical trials and other research opportunities is important to discovering new disease treatments and better ways to detect, diagnose, and reduce disease risk. The WISDOM (Women Informed to Screen Depending on Measures of risk) Study is a multi-site, pragmatic trial with webbased participation based at the University of California at San Francisco (UCSF) that aims to move breast cancer screening away from its current one-size-fitsall approach to one that is personalized based on each woman’s individual risk.

Methods

We created a hub and spoke recruitment model with the San Francisco VA Medical Center (SFVAMC) serving as the central hub of passive recruitment activities and eligible VA facilities that agreed to participate serving as the spoke recruitment sites. Eligible facilities had at least 3,000 women patients, VA clinical genetic services available, a site lead from the VA Women’s Health-Practice-Based Research Network, and mammography on site. Site participation involved permission for the research team to email eligible patients (women aged 40-74 without prior breast cancer diagnosis) about the WISDOM Study. We evaluated the effectiveness of the recruitment by assessing trends in enrollment and monitoring participation of VA patients in the WISDOM Study. Analysis: Pre/post frequencies of women consenting to participate in the WISDOM Study.

Results

From 5/24/2021 through 6/21/2021, we emailed 27,061 eligible VA patients from six participating VA facilities. Prior to the VA emailing, an average of 22 women per week consented to participating in the WISDOM Study and none were Veterans. After the first month of the VA emailing, an average of 186 women per week consented – a 7.5-fold increase. Additionally, during the first month of VA emailing, 81% of women registering with the WISDOM Study said they heard about the study from the VA.

Implications

The VA has recently approved of emailing as a method for recruiting research subjects. Our results demonstrate this is a feasible approach for precision medicine research, a growing area of research in VA and at academic affiliates.

Although most children and adolescents with cancer have mild illness from COVID-19 infection, some do experience severe disease and a small percentage even die, according to a recent analysis.

The findings, published online in Lancet Oncology, represent the first global registry data spanning different income groups to report COVID-19 outcomes in pediatric oncology patients.

“We wanted to create a global pool of evidence to answer the question: Do we see severe [COVID-19] infection [in children with cancer]?” corresponding author Sheena Mukkada, MD, St. Jude Children’s Research Hospital, Memphis, said in an interview.

In a cohort of 1,319 pediatric patients followed for 30 days, Dr. Mukkada and colleagues reported that 80% of these patients had asymptomatic to moderate disease from COVID-19, while 1 in 5 experienced severe or critical illness and almost 4% died – four times the mortality rate observed in published cohorts of general pediatric patients.

The results highlight that “children and adolescents with cancer generally recover without incident from COVID-19, but can have a severe course of infection,” the authors concluded.

And knowing that some children can get very sick, investigators wanted “to identify who these patients are so that we can prioritize and protect that group,” she added.

Echoing that sentiment, Kathy Pritchard-Jones, MD, president of the International Society of Paediatric Oncology and coauthor on the study, noted in a press release that, “by working together to create this global registry, we have enabled hospitals around the world to rapidly share and learn how COVID-19 is affecting children with cancer.”

Dr. Pritchard-Jones commented that overall these results provide reassurance that “many children can continue their cancer treatment safely, but they also highlight important clinical features that may predict a more severe clinical course and the need for greater vigilance for some patients.”
 

Inside the Global Registry data

The Global Registry of COVID-19 in Childhood Cancer, created jointly by St. Jude Children’s Research Hospital and SIOP, included data from 131 institutions in 45 countries. Children recruited into the registry between April 2020 and February 2021 ranged in age from infancy to 18 years old.  

Most patients remained asymptomatic (35%) or experienced mild to moderate illness (45%), though 20% did develop severe or critical illness.

The investigators highlighted several factors associated with a greater risk of developing more severe illness from COVID-19, which included cancer type, intensity of therapy, age, absolute lymphocyte count, and presence of comorbidities or COVID-19 symptoms.

Notably, more than 80% of either severe or critical infections occurred in patients with hematologic malignancies – with 56% of cases in patients with acute lymphoblastic lymphoma or acute lymphoblastic leukemia – followed by extracranial solid tumors (15.8%), and central nervous system tumors (2.7%).

In patients with acute lymphoblastic leukemia or acute lymphoblastic lymphoma, severe or critical disease was most common in those receiving induction therapy (30%), relapse or refractory therapy (30%), and those in the maintenance or continuation phase of therapy (19%).

Older age was associated with a higher likelihood of having severe disease – with the lowest risk in infants (9.7%) and the highest in the 15- to 18-year-old cohort (27.3%).

Patients with lymphopenia who had an absolute lymphocyte count of 300 cells per mm³ or less and an absolute neutrophil count of 500 cells per mm³ or more also had an elevated risk of severe illness from COVID-19.

Regarding whether the presence of lymphopenia or neutropenia should change the treatment approach, Dr. Mukkada noted that, when possible, these patients should receive antiviral treatment, such as remdesivir, if the center has antivirals, or be prioritized for hospital admission.

Modifying cancer treatment might be recommended if patients are highly lymphopenic or have very low neutrophil counts, but a more effective strategy is simply to ensure that age-eligible children and adolescents with cancer or who have had a hematopoietic stem-cell transplantation have been fully vaccinated against COVID-19. For children who are not yet age-eligible, everyone around them should be vaccinated.

Pediatric patients in low- and middle-income countries were also more likely to have severe or critical outcomes from COVID-19 (41.7%), compared with patients in other income groups (23.9%).

The impact of COVID-19 “has been felt in every corner of the world, but particularly in low- and middle-income countries, compared to high-income countries,” senior author Carlos Rodriguez-Galindo, MD, global director at St. Jude, said in a statement.

In terms of the intersection of cancer treatment and COVID diagnosis, almost 83% of pediatric patients were receiving treatment for their cancer. Chemotherapy was withheld in about 45% of these patients and some modification to the treatment regimen occurred in almost 56% of participants on active therapy.

“Treatment modifications were least common in patients from upper-middle–income countries, compared with other income groups,” the authors wrote.

Although an interesting observation, Dr. Mukkada noted that the registry data could not explain why treatment modifications occurred less frequently in upper-middle income countries as opposed to high-income and lower-income countries.
 

U.K. Monitoring Project

Not all studies, however, have found that COVID-19 infection is significantly more severe in children with cancer. In a 2020 report from the U.K. Paediatric Coronavirus Cancer Monitoring Project, researchers evaluated all children in the United Kingdom under the age of 16 diagnosed with COVID and cancer.

“[Given that] we had complete coverage of every center in the U.K. that cares for children with cancer, we are confident that we picked up at least all the severe or critical cases,” lead author Gerard Millen, MD, honorary clinical research fellow, University of Birmingham (England), said in an interview.

Between March 2020 and July 2020, Dr. Millen and colleagues identified 54 positive cases of COVID-19, 15 (28%) of which were asymptomatic, 34 (63%) mild, and 4 (7.4%) severe or critical – more in line with the incidence of severe illness reported in the general pediatric population.

“Thankfully, we had no children with cancer in the U.K. who died from COVID-19,” Dr. Millen noted. “Overall, in the U.K., we have taken the approach that the majority of children with cancer in this country are at very low risk from COVID-19 and that we do not have good evidence to modify their treatment.”

Dr. Millen pointed out that the data in the U.K. study were “remarkably similar” to those from the high-income countries in the global St. Jude/SIOP cohort, where 7.4% of patients in that cohort had severe or critical disease, compared with 7.4% of patients from their own U.K. cohort.

“I think many of the key differences between the two cohorts reflect the fact that access to treatment in many low- to middle-income countries is more challenging with many factors contributing to overall poorer outcomes for both cancer and noncancer metrics,” Dr. Millen said.

Both the U.K. and registry studies were performed prior to vaccinations becoming available to older children, and before the emergence of certain variants, including the Delta variant, which is responsible for the most recent surge of COVID-19 infections around the world.

Data on COVID-19 vaccination in children with cancer are limited but promising so far.

As for whether the Delta variant might affect outcomes for children with cancer and COVID-19, Dr. Mukkada could only speculate, but she noted that “what we are hearing anecdotally about the [Delta] disease being more severe, even in patients who don’t have cancer, is leading us to say that we can’t close the registry yet. We are still actively enrolling children.”

The study was funded by the American Lebanese Syrian Associated Charities and the National Cancer Institute. The study authors and Dr. Millen disclosed no relevant financial relationships.

“I think many of the key differences between the two cohorts reflect the fact that access to treatment in many low- to middle-income countries is more challenging with many factors contributing to overall poorer outcomes for both cancer and noncancer metrics,” Dr. Millen said.

Both the U.K. and registry studies were performed prior to vaccinations becoming available to older children, and before the emergence of certain variants, including the Delta variant, which is responsible for the most recent surge of COVID-19 infections around the world.

Data on COVID-19 vaccination in children with cancer are limited but promising so far.

As for whether the Delta variant might affect outcomes for children with cancer and COVID-19, Dr. Mukkada could only speculate, but she noted that “what we are hearing anecdotally about the [Delta] disease being more severe, even in patients who don’t have cancer, is leading us to say that we can’t close the registry yet. We are still actively enrolling children.”

The study was funded by the American Lebanese Syrian Associated Charities and the National Cancer Institute. The study authors and Dr. Millen disclosed no relevant financial relationships.

Although most children and adolescents with cancer have mild illness from COVID-19 infection, some do experience severe disease and a small percentage even die, according to a recent analysis.

The findings, published online in Lancet Oncology, represent the first global registry data spanning different income groups to report COVID-19 outcomes in pediatric oncology patients.

“We wanted to create a global pool of evidence to answer the question: Do we see severe [COVID-19] infection [in children with cancer]?” corresponding author Sheena Mukkada, MD, St. Jude Children’s Research Hospital, Memphis, said in an interview.

In a cohort of 1,319 pediatric patients followed for 30 days, Dr. Mukkada and colleagues reported that 80% of these patients had asymptomatic to moderate disease from COVID-19, while 1 in 5 experienced severe or critical illness and almost 4% died – four times the mortality rate observed in published cohorts of general pediatric patients.

The results highlight that “children and adolescents with cancer generally recover without incident from COVID-19, but can have a severe course of infection,” the authors concluded.

And knowing that some children can get very sick, investigators wanted “to identify who these patients are so that we can prioritize and protect that group,” she added.

Echoing that sentiment, Kathy Pritchard-Jones, MD, president of the International Society of Paediatric Oncology and coauthor on the study, noted in a press release that, “by working together to create this global registry, we have enabled hospitals around the world to rapidly share and learn how COVID-19 is affecting children with cancer.”

Dr. Pritchard-Jones commented that overall these results provide reassurance that “many children can continue their cancer treatment safely, but they also highlight important clinical features that may predict a more severe clinical course and the need for greater vigilance for some patients.”
 

Inside the Global Registry data

The Global Registry of COVID-19 in Childhood Cancer, created jointly by St. Jude Children’s Research Hospital and SIOP, included data from 131 institutions in 45 countries. Children recruited into the registry between April 2020 and February 2021 ranged in age from infancy to 18 years old.  

Most patients remained asymptomatic (35%) or experienced mild to moderate illness (45%), though 20% did develop severe or critical illness.

The investigators highlighted several factors associated with a greater risk of developing more severe illness from COVID-19, which included cancer type, intensity of therapy, age, absolute lymphocyte count, and presence of comorbidities or COVID-19 symptoms.

Notably, more than 80% of either severe or critical infections occurred in patients with hematologic malignancies – with 56% of cases in patients with acute lymphoblastic lymphoma or acute lymphoblastic leukemia – followed by extracranial solid tumors (15.8%), and central nervous system tumors (2.7%).

In patients with acute lymphoblastic leukemia or acute lymphoblastic lymphoma, severe or critical disease was most common in those receiving induction therapy (30%), relapse or refractory therapy (30%), and those in the maintenance or continuation phase of therapy (19%).

Older age was associated with a higher likelihood of having severe disease – with the lowest risk in infants (9.7%) and the highest in the 15- to 18-year-old cohort (27.3%).

Patients with lymphopenia who had an absolute lymphocyte count of 300 cells per mm³ or less and an absolute neutrophil count of 500 cells per mm³ or more also had an elevated risk of severe illness from COVID-19.

Regarding whether the presence of lymphopenia or neutropenia should change the treatment approach, Dr. Mukkada noted that, when possible, these patients should receive antiviral treatment, such as remdesivir, if the center has antivirals, or be prioritized for hospital admission.

Modifying cancer treatment might be recommended if patients are highly lymphopenic or have very low neutrophil counts, but a more effective strategy is simply to ensure that age-eligible children and adolescents with cancer or who have had a hematopoietic stem-cell transplantation have been fully vaccinated against COVID-19. For children who are not yet age-eligible, everyone around them should be vaccinated.

Pediatric patients in low- and middle-income countries were also more likely to have severe or critical outcomes from COVID-19 (41.7%), compared with patients in other income groups (23.9%).

The impact of COVID-19 “has been felt in every corner of the world, but particularly in low- and middle-income countries, compared to high-income countries,” senior author Carlos Rodriguez-Galindo, MD, global director at St. Jude, said in a statement.

In terms of the intersection of cancer treatment and COVID diagnosis, almost 83% of pediatric patients were receiving treatment for their cancer. Chemotherapy was withheld in about 45% of these patients and some modification to the treatment regimen occurred in almost 56% of participants on active therapy.

“Treatment modifications were least common in patients from upper-middle–income countries, compared with other income groups,” the authors wrote.

Although an interesting observation, Dr. Mukkada noted that the registry data could not explain why treatment modifications occurred less frequently in upper-middle income countries as opposed to high-income and lower-income countries.
 

U.K. Monitoring Project

Not all studies, however, have found that COVID-19 infection is significantly more severe in children with cancer. In a 2020 report from the U.K. Paediatric Coronavirus Cancer Monitoring Project, researchers evaluated all children in the United Kingdom under the age of 16 diagnosed with COVID and cancer.

“[Given that] we had complete coverage of every center in the U.K. that cares for children with cancer, we are confident that we picked up at least all the severe or critical cases,” lead author Gerard Millen, MD, honorary clinical research fellow, University of Birmingham (England), said in an interview.

Between March 2020 and July 2020, Dr. Millen and colleagues identified 54 positive cases of COVID-19, 15 (28%) of which were asymptomatic, 34 (63%) mild, and 4 (7.4%) severe or critical – more in line with the incidence of severe illness reported in the general pediatric population.

“Thankfully, we had no children with cancer in the U.K. who died from COVID-19,” Dr. Millen noted. “Overall, in the U.K., we have taken the approach that the majority of children with cancer in this country are at very low risk from COVID-19 and that we do not have good evidence to modify their treatment.”

Dr. Millen pointed out that the data in the U.K. study were “remarkably similar” to those from the high-income countries in the global St. Jude/SIOP cohort, where 7.4% of patients in that cohort had severe or critical disease, compared with 7.4% of patients from their own U.K. cohort.

A recent survey shows that fewer than half of community oncologists use biomarker testing to guide patient discussions about treatment, which compares with 73% of academic clinicians.

The findings, reported at the 2020 World Conference on Lung Cancer, which was rescheduled for January 2021, highlight the potential for unequal application of the latest advances in cancer genomics and targeted therapies throughout the health care system, which could worsen existing disparities in underserved populations, according to Leigh Boehmer, PharmD, medical director for the Association of Community Cancer Centers, Rockville, Md.

The survey – a mixed-methods approach for assessing practice patterns, attitudes, barriers, and resource needs related to biomarker testing among clinicians – was developed by the ACCC in partnership with the LUNGevity Foundation and administered to clinicians caring for patients with non–small cell lung cancer who are uninsured or covered by Medicaid.

Of 99 respondents, more than 85% were physicians and 68% worked in a community setting. Only 40% indicated they were very familiar or extremely familiar with 2018 Molecular Testing Guidelines for Lung Cancer from the College of American Pathologists, the International Association for the Study of Lung Cancer, and the Association for Molecular Pathology.

Clinicians were most confident about selecting appropriate tests to use, interpreting test results, and prognosticating based on test results, with 77%, 74%, and 74%, respectively, saying they are very confident or extremely confident in those areas. They were less confident about determining when to order testing and in coordinating care across the multidisciplinary team, with 59% and 64%, respectively, saying they were very confident or extremely confident in those areas, Dr. Boehmer reported at the conference.

The shortcomings with respect to communication across teams were echoed in two focus groups convened to further validate the survey results, he noted.

As for the reasons why clinicians ordered biomarker testing, 88% and 82% of community and academic clinicians, respectively, said they did so to help make targeted treatment decisions.

“Only 48% of community clinicians indicated that they use biomarker testing to guide patient discussions, compared to 73% of academic clinicians,” he said. “That finding was considered statistically significant.”

With respect to decision-making about biomarker testing, 41% said they prefer to share the responsibility with patients, whereas 52% said they prefer to make the final decision.

“Shedding further light on this situation, focus group participants expressed that patients lacked comprehension and interest about what testing entails and what testing means for their treatment options,” Dr. Boehmer noted.

In order to make more informed decisions about biomarker testing, respondents said they need more information on financial resources for patient assistance (26%) and education around both published guidelines and practical implications of the clinical data (21%).

When asked about patients’ information needs, 23% said their patients need psychosocial support, 22% said they need financial assistance, and 9% said their patients have no additional resource needs.

However, only 27% said they provide patients with resources related to psychosocial support services, and only 44% share financial assistance information, he said.

Further, the fact that 9% said their patients need no additional resources represents “a disconnect” from the findings of the survey and focus groups, he added.

“We believe that this study identifies key areas of ongoing clinician need related to biomarker testing, including things like increased guideline familiarity, practical applications of guideline-concordant testing, and … how to optimally coordinate multidisciplinary care delivery,” Dr. Boehmer said. “Professional organizations … in partnership with patient advocacy organizations or groups should focus on developing those patient education materials … and tools for improving patient-clinician discussions about biomarker testing.”

The ACCC will be working with the LUNGevity Foundation and the Center for Business Models in Healthcare to develop an intervention to ensure that such discussions are “easily integrated into the care process for every patient,” he noted.

Such efforts are important for ensuring that clinicians are informed about the value of biomarker testing and about guidelines for testing so that patients receive the best possible care, said invited discussant Joshua Sabari, MD, of New York University Langone Health’s Perlmutter Cancer Center.

“I know that, in clinic, when meeting a new patient with non–small cell lung cancer, it’s critical to understand the driver alteration, not only for prognosis, but also for goals-of-care discussion, as well as potential treatment option,” Dr. Sabari said.

Dr. Boehmer reported consulting for Pfizer. Dr. Sabari reported consulting and advisory board membership for multiple pharmaceutical companies.

Some women with the most-difficult-to-treat form of advanced breast cancer who have positively responded to atezolizumab (Tecentriq) are reporting panic and anxiety because oncologists have suddenly discontinued their prescriptions.

The discontinuance appears to be in reaction to an announcement by the manufacturer (Genentech) in late August that it has voluntarily withdrawn its application for accelerated approval of the drug for use in metastatic triple-negative breast cancer (mTNBC).

However, experts stress that discontinuing atezolizumab is not advised if a patient is responding to or is stable on the immune checkpoint inhibitor.

“I think the Genentech announcement has been misinterpreted,” Maryam Lustberg, MD, of Yale Cancer Center, New Haven, Conn., said in an interview. “The consensus opinion from all academic breast oncologists is that people should not be switching off atezolizumab if they are responding. They should not be changing their immunotherapy.”

Dr. Lustberg said the announcement had two major points: “don’t start a new patient on atezolizumab,” and the company is “committed” to supplying the drug to patients whose conditions are stable or responding.

Nevertheless, some patients with mTNBC were recently in a state of escalating emotional upset, said one patient advocate.

“The level of panic among those currently on & responding well to Atezo is growing quickly,” tweeted Janice Cowden on Sept. 5, a former nurse living with mTNBC in Bradenton, Fla.

Ms. Cowden explained that “at least 10-20 patients” were “pulled [off the drug by their oncologists] this past week who have been stable/no evidence of disease/no evidence of disease activity on Tecentriq.”

She estimated that as many as 50 patients in the 2,200-member Triple Negative BC Stage 4 Facebook group who have been responding to the drug were abruptly de-prescribed atezolizumab since the Aug. 27 announcement from Genentech.

Many women learned of the change via patient portals or text messaging, not directly from their physicians, Cowden told Medscape Medical News.

Some of the women had been taking atezolizumab for 2-3 years, including those with no evidence of disease, she said. “Finding out that their oncologist was discontinuing a treatment that was working for them has been driving so much anxiety and stress,” Ms. Cowden emphasized.

Most market withdrawals of drugs are related to safety, but that is not the case with atezolizumab, said Sara Horton, MD, of Howard University, Washington. She was speaking at the recent Facebook webinar on atezolizumab and mTNBC that was sponsored by the TNBC Foundation and the Young Survivors Coalition.

In the case of atezolizumab, it was a question about efficacy that prompted the withdrawal. After the indication was granted an accelerated approval on the basis of response data, a confirmatory trial set out to show clinical benefit. However, the confirmatory phase 3 IMpassion131 trial did not do so: it found that atezolizumab plus paclitaxel did not significantly reduce the risk for cancer progression and death in comparison with paclitaxel plus placebo among patients with TNBC with tumors that were positive for programmed cell death protein–1 (PD-L1), as reported by Medscape Medical News.

These results were discussed by the Food and Drug Administration on the first day of a historic 3-day meeting on accelerated approvals in April 2021. Despite the failure of confirmation of clinical benefit, the advisory panel voted 7-2 in favor of keeping the approval in place for atezolizumab in TNBC. At the same time, it urged Genentech to carry out more studies to show that the drug works in this patient population.

The company apparently decided not to do that and instead voluntarily withdrew the application for the indication some 4 months later.

During the recent TNBC Foundation webinar, Genentech official Lauren Davis said that the company sent letters about this decision to atezolizumab-prescribing physicians and included another letter that was to be shared with patients. Ms. Davis had not responded to this news organization’s request to review the communications at the time this article was published.

At the webinar, Ms. Davis did clarify that current atezolizumab patients (who are responding to the drug), who have commercial insurance, and who benefit from Genentech’s copay program will continue to receive the benefit until June 2022.

In its August announcement, Genentech said it decided to withdraw the atezolizumab approval on the basis of the FDA’s assessment of the “current mTNBC treatment landscape and in accordance with the requirements of the accelerated approval program.”

That landscape presumably includes pembrolizumab (Keytruda), which received a full approval for a TNBC indication similar to that of atezolizumab in July. That full approval was based on findings from the randomized, phase 3 KEYNOTE-522 trial, which showed significantly prolonged event-free survival with the pembrolizumab regimen in comparison with neoadjuvant chemotherapy alone for previously untreated stage II or III TNBC. Details of these clinical data will be presented at the upcoming annual meeting of the European Society of Medical Oncology.
 

Switching the immunotherapy?

Some U.S. oncologists have been telling patients with mTNBC that the atezolizumab withdrawal is “not an issue” because the new full approval of pembrolizumab in this setting will allow prescriptions to be switched, said patient advocate Ms. Cowden.

However, experts have said that no patient who is responding to or whose condition is stable with atezolizumab should switch immunotherapies. “This is a very aggressive disease,” reminded Dr. Lustberg.

Switching the immunotherapies is complicated by the difference in the respective drugs’ companion biomarker assays used to establish the presence of PD-L1.

Dr. Lustberg explained that patients who are not responding to atezolizumab and who now want to try pembrolizumab will have to be assessed with the CTS assay.

“About 22% of the patients who are positive for the atezolizumab biomarker assay SP-142 are not going to be positive for the CTS,” she said.

In other words, about one in four patients with mTNBC who are taking atezolizumab will not qualify for treatment with pembrolizumab.

Rebecca Shatsky, MD, of the University of California, San Diego, echoed those comments in an email to this news organization – and emphatically discouraged switching off atezolizumab (and going on pembrolizumab) if a patient is having success (i.e., stable disease or positive response).

“The two groups don’t always overlap, so it isn’t an easy switch. That’s why if they are already responding, I would NOT have them stop the drug,” she said.

Not every mTNBC patient receiving – and responding to – atezolizumab has had the unfortunate experience of having their prescription canceled.

Johanna Rauhala, of San Francisco, who is a former middle-school teacher and who writes the blog Pink Stinks, has been taking atezolizumab for 2 years. She has had a partial response and now, after taking the immunotherapy in combination with chemotherapy (gemcitabine and carboplatin), has stable disease. Currently, she is taking single-agent atezolizumab..

Ms. Rauhala has been living with mTNBC for 5 years. She said in an interview that she was “very surprised and concerned” to learn about Genentech’s withdrawal of its accelerated approval. She said that at her next treatment appointment, she was “probably going to ask the oncology nurse first [about the atezolizumab withdrawal] – because they are the front line, and I will then follow-up with my doctor. But I can’t imagine that they will take away something that is working.”

Dr. Shatsky, Dr. Horton, and Dr. Lunsberg report no relevant financial disclosures.

Some U.S. oncologists have been telling patients with mTNBC that the atezolizumab withdrawal is “not an issue” because the new full approval of pembrolizumab in this setting will allow prescriptions to be switched, said patient advocate Ms. Cowden.

However, experts have said that no patient who is responding to or whose condition is stable with atezolizumab should switch immunotherapies. “This is a very aggressive disease,” reminded Dr. Lustberg.

Switching the immunotherapies is complicated by the difference in the respective drugs’ companion biomarker assays used to establish the presence of PD-L1.

Dr. Lustberg explained that patients who are not responding to atezolizumab and who now want to try pembrolizumab will have to be assessed with the CTS assay.

“About 22% of the patients who are positive for the atezolizumab biomarker assay SP-142 are not going to be positive for the CTS,” she said.

In other words, about one in four patients with mTNBC who are taking atezolizumab will not qualify for treatment with pembrolizumab.

Rebecca Shatsky, MD, of the University of California, San Diego, echoed those comments in an email to this news organization – and emphatically discouraged switching off atezolizumab (and going on pembrolizumab) if a patient is having success (i.e., stable disease or positive response).

“The two groups don’t always overlap, so it isn’t an easy switch. That’s why if they are already responding, I would NOT have them stop the drug,” she said.

Not every mTNBC patient receiving – and responding to – atezolizumab has had the unfortunate experience of having their prescription canceled.

Johanna Rauhala, of San Francisco, who is a former middle-school teacher and who writes the blog Pink Stinks, has been taking atezolizumab for 2 years. She has had a partial response and now, after taking the immunotherapy in combination with chemotherapy (gemcitabine and carboplatin), has stable disease. Currently, she is taking single-agent atezolizumab..

Ms. Rauhala has been living with mTNBC for 5 years. She said in an interview that she was “very surprised and concerned” to learn about Genentech’s withdrawal of its accelerated approval. She said that at her next treatment appointment, she was “probably going to ask the oncology nurse first [about the atezolizumab withdrawal] – because they are the front line, and I will then follow-up with my doctor. But I can’t imagine that they will take away something that is working.”

Dr. Shatsky, Dr. Horton, and Dr. Lunsberg report no relevant financial disclosures.

Some women with the most-difficult-to-treat form of advanced breast cancer who have positively responded to atezolizumab (Tecentriq) are reporting panic and anxiety because oncologists have suddenly discontinued their prescriptions.

The discontinuance appears to be in reaction to an announcement by the manufacturer (Genentech) in late August that it has voluntarily withdrawn its application for accelerated approval of the drug for use in metastatic triple-negative breast cancer (mTNBC).

However, experts stress that discontinuing atezolizumab is not advised if a patient is responding to or is stable on the immune checkpoint inhibitor.

“I think the Genentech announcement has been misinterpreted,” Maryam Lustberg, MD, of Yale Cancer Center, New Haven, Conn., said in an interview. “The consensus opinion from all academic breast oncologists is that people should not be switching off atezolizumab if they are responding. They should not be changing their immunotherapy.”

Dr. Lustberg said the announcement had two major points: “don’t start a new patient on atezolizumab,” and the company is “committed” to supplying the drug to patients whose conditions are stable or responding.

Nevertheless, some patients with mTNBC were recently in a state of escalating emotional upset, said one patient advocate.

“The level of panic among those currently on & responding well to Atezo is growing quickly,” tweeted Janice Cowden on Sept. 5, a former nurse living with mTNBC in Bradenton, Fla.

Ms. Cowden explained that “at least 10-20 patients” were “pulled [off the drug by their oncologists] this past week who have been stable/no evidence of disease/no evidence of disease activity on Tecentriq.”

She estimated that as many as 50 patients in the 2,200-member Triple Negative BC Stage 4 Facebook group who have been responding to the drug were abruptly de-prescribed atezolizumab since the Aug. 27 announcement from Genentech.

Many women learned of the change via patient portals or text messaging, not directly from their physicians, Cowden told Medscape Medical News.

Some of the women had been taking atezolizumab for 2-3 years, including those with no evidence of disease, she said. “Finding out that their oncologist was discontinuing a treatment that was working for them has been driving so much anxiety and stress,” Ms. Cowden emphasized.

Most market withdrawals of drugs are related to safety, but that is not the case with atezolizumab, said Sara Horton, MD, of Howard University, Washington. She was speaking at the recent Facebook webinar on atezolizumab and mTNBC that was sponsored by the TNBC Foundation and the Young Survivors Coalition.

In the case of atezolizumab, it was a question about efficacy that prompted the withdrawal. After the indication was granted an accelerated approval on the basis of response data, a confirmatory trial set out to show clinical benefit. However, the confirmatory phase 3 IMpassion131 trial did not do so: it found that atezolizumab plus paclitaxel did not significantly reduce the risk for cancer progression and death in comparison with paclitaxel plus placebo among patients with TNBC with tumors that were positive for programmed cell death protein–1 (PD-L1), as reported by Medscape Medical News.

These results were discussed by the Food and Drug Administration on the first day of a historic 3-day meeting on accelerated approvals in April 2021. Despite the failure of confirmation of clinical benefit, the advisory panel voted 7-2 in favor of keeping the approval in place for atezolizumab in TNBC. At the same time, it urged Genentech to carry out more studies to show that the drug works in this patient population.

The company apparently decided not to do that and instead voluntarily withdrew the application for the indication some 4 months later.

During the recent TNBC Foundation webinar, Genentech official Lauren Davis said that the company sent letters about this decision to atezolizumab-prescribing physicians and included another letter that was to be shared with patients. Ms. Davis had not responded to this news organization’s request to review the communications at the time this article was published.

At the webinar, Ms. Davis did clarify that current atezolizumab patients (who are responding to the drug), who have commercial insurance, and who benefit from Genentech’s copay program will continue to receive the benefit until June 2022.

In its August announcement, Genentech said it decided to withdraw the atezolizumab approval on the basis of the FDA’s assessment of the “current mTNBC treatment landscape and in accordance with the requirements of the accelerated approval program.”

That landscape presumably includes pembrolizumab (Keytruda), which received a full approval for a TNBC indication similar to that of atezolizumab in July. That full approval was based on findings from the randomized, phase 3 KEYNOTE-522 trial, which showed significantly prolonged event-free survival with the pembrolizumab regimen in comparison with neoadjuvant chemotherapy alone for previously untreated stage II or III TNBC. Details of these clinical data will be presented at the upcoming annual meeting of the European Society of Medical Oncology.

The U.S. Food and Drug Administration has granted an accelerated approval to mobocertinib (Exkivity, Takeda) for the treatment of patients with locally advanced or metastatic non–small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 20 insertion mutations.

The drug is limited to use in patients whose disease has progressed on or after platinum-based chemotherapy and who have had the EGFR Exon 20 insertion mutation detected on an FDA-approved test.

Mobocertinib is the first oral tyrosine kinase inhibitor (TKI) specifically designed to target these mutations, which are less common than the more predominant EGFR mutations in this lung cancer.

“EGFR Exon 20 insertion+ NSCLC is an underserved cancer that we have been unable to target effectively with traditional EGFR TKIs,” said Pasi Jänne, MD, PhD, of the Dana Farber Cancer Institute, Boston, in a press statement from the maker, Takeda.

“The approval of [mobocertinib] marks another important step forward that provides physicians and their patients with a new targeted oral therapy specifically designed for this patient population that has shown clinically meaningful and sustained responses,” Dr. Jänne added.

According to the company, EGFR Exon 20 insertion+ NSCLC makes up approximately 1%-2% of patients with NSCLC and is more common in Asian populations compared with Western populations.

The new approval is based on overall response rate (ORR) and duration of response (DoR) results from a phase 1/2 trial consisting of 114 patients with EGFR Exon 20 insertion+ NSCLC who received prior platinum-based therapy and were treated with the 160-mg dose.

Per an independent review committee, mobocertinib demonstrated a confirmed ORR of 28% and a median DoR of 17.5 months.

Median overall survival was 24 months and median progression-free survival was 7.3 months.

The FDA-approved next-generation sequencing (NGS) companion diagnostic for mobocertinib is Thermo Fisher Scientific’s Oncomine Dx Target Test, which identifies NSCLC patients with EGFR Exon 20 insertions.

“NGS testing is critical for these patients, as it can enable more accurate diagnoses compared to polymerase chain reaction (PCR) testing, which detects less than 50% of EGFR Exon 20 insertions,” according to the company.

Results from the phase 1/2 trial used in the FDA approval were presented at the 2021 American Society of Clinical Oncology Annual Meeting.

The most common adverse reactions (greater than 20%) were diarrhea, rash, nausea, stomatitis, vomiting, decreased appetite, paronychia, fatigue, dry skin, and musculoskeletal pain, according to the company.

The prescribing information includes a boxed warning for QTc prolongation and Torsades de Pointes, and warnings and precautions for interstitial lung disease/pneumonitis, cardiac toxicity, and diarrhea.

“Patients with EGFR Exon 20 insertion+ NSCLC have historically faced a unique set of challenges living with a very rare lung cancer that is not only underdiagnosed but also lacking targeted treatment options that can improve response rates,” said Marcia Horn, executive director, Exon 20 Group at the International Cancer Advocacy Network, in the press statement.

The FDA review was conducted under Project Orbis, an FDA initiative that enables concurrent submission and review of oncology products among international partners.

The new drug was also granted priority review and received breakthrough therapy, fast track, and orphan drug designations from the FDA.
