Metastatic Breast Cancer

CHICAGO – One-third of patients with cancer also experience anxiety or depression, and an estimated 70% of the 18 million patients with cancer and cancer survivors in the US experience emotional symptoms, including fear of recurrence.

Despite many having these symptoms, few patients with cancer have access to psycho-oncologic support.

A digital cognitive-behavioral stress management (CBSM) application may help to ease some of the burden, reported Allison Ramiller, MPH, of Blue Note Therapeutics in San Francisco, which developed the app version of the program.

In the randomized controlled RESTORE study, use of the cell phone–based CBSM app was associated with significantly greater reduction in symptoms of anxiety and depression compared with a digital health education control app.

In addition, patients assigned to the CBSM app were twice as likely as control persons to report that their symptoms were “much” or “very much” improved after using the app for 12 weeks, Ms. Ramiller reported at an oral abstract session at the annual meeting of the American Society of Clinical Oncology (ASCO).

However, the investigators did not report baseline characteristics of patients in each of the study arms, which might have helped to clarify the depth of the effects they saw.

The CBSM program was developed by Michael H. Antoni, PhD, and colleagues in the University of Miami Health System. It is based on cognitive-behavioral therapy but also includes stress management and relaxation techniques to help patients cope with cancer-specific stress.

“”It has been clinically validated and shown to benefit patients with cancer,” Ms. Ramiller said. “However, access is a problem,” she said.

“There aren’t enough qualified, trained providers for the need, and patients with cancer encounter barriers to in-person participation, including things like transportation or financial barriers. So to overcome this, we developed a digitized version of CBSM,” she explained.
 

Impressive and elegant

“Everything about [the study] I thought was very impressive, very elegant, very nicely done,” said invited discussant Raymond U. Osarogiagbon, MBBS, FACP, chief scientist at Baptist Memorial Health Care Corp in Memphis, Tenn.

“They showed efficacy, they showed safety – very nice – user friendliness – very good. Certainly they look like they’re trying to address a highly important, unmet need in a very elegant way. Certainly, they pointed out it needs longer follow-up to see sustainability. We need to see will this work in other settings. Will this be cost-effective? You’ve gotta believe it probably will be,” he said.

CBSM has previously been shown to help patients with cancer reduce stress, improve general and cancer-specific quality of life at various stages of treatment, reduce symptom burden, and improve coping skills, Ms. Ramiller said.

To see whether these benefits could be conveyed digitally rather than in face-to-face encounters, Ms. Ramiller and colleagues worked with Dr. Antoni to develop the CBSM app.

Patients using the app received therapeutic content over 10 sessions with audio, video, and interactive tools that mimicked the sessions they would have received during in-person interventions.

They then compared the app against the control educational app in the randomized, decentralized RESTORE study.
 

High-quality control

Ms. Ramiller said that the control app set “a high bar.”

“The control also offered 10 interactive self-guided sessions. Both treatment apps were professionally designed and visually similar in styling, and they were presented as digital therapeutic-specific for cancer patients. And they were also in a match condition, meaning they received the same attention from study staff and cadence of reminders, but importantly, only the intervention app was based on CBSM,” she explained.

A total of 449 patients with cancers of stage I–III who were undergoing active systemic treatment or were planning to undergo such treatment within 6 months were randomly assigned to the CBSM app or the control app.

The CBSM app was superior to the control app for the primary outcome of anxiety reduction over baseline, as measured at 4, 8 and 12 weeks by the Patient-Reported Outcomes Measurement Information System Anxiety Scale (PROMIS-A) (beta = -.03; P = .019).

CBSM was also significantly better than the control app for the secondary endpoints of reducing symptoms of depression, as measured by the PROMIS-D scale (beta = -.02, P = .042), and also at increasing the percentage of patients who reported improvement in anxiety and depression symptoms on the Patient Global Impression of Change instrument (P < .001)

An extension study of the durability of the effects at 3 and 6 months is underway.

The investigators noted that the incremental cost of management of anxiety or depression is greater than $17,000 per patient per year.

“One of the big promises of a digital therapeutic like this is that it could potentially reduce costs,” Ms. Ramiller told the audience, but she acknowledged, “More work is really needed, however, to directly test the potential savings.”

The RESTORE study is funded by Blue Note Therapeutics. Dr. Osarogiagbon owns stock in Gilead, Lilly, and Pfizer, has received honoraria from Biodesix and Medscape, and has a consulting or advisory role for the American Cancer Society AstraZeneca, Genentech/Roche, LUNGevity, National Cancer Institute, and Triptych Health Partners.

CHICAGO – Trastuzumab deruxtecan (T-DXd) (Enhertu) already has proven efficacy against HER2-expressing metastatic breast, gastroesophageal, and lung cancers.

Now, preliminary data from an ongoing study indicate that T-DXd, which combines an antibody targeted to HER2 with a toxic payload, could be an effective therapy for a broader range of advanced solid tumors that express HER2, including malignancies of the cervix, endometrium, ovaries, bladder, and other sites.

The findings come from the ongoing DESTINY-PanTumor02 trial. Among 267 patients with solid tumors at various organ sites, the investigator-assessed objective response rate among all patients was 37.1%, and ranged from as high as 57.5% for patients with endometrial cancers to as low as 4% for patients with pancreatic cancer, reported Funda Meric-Bernstam, MD, from the University of Texas MD Anderson Cancer Center, Houston.

For patients with tumors that had HER2 immunohistochemistry (IHC) scores of 3+, the highest level of HER2 expression, the overall response rate was 61.3%..

The responses were also durable, with a median duration of 11.8 months among all patients and 22.1 months among patients with IHC 3+ scores.

“Our data to date showed that T-DXd had clinically meaningful activity across a variety of tumor types,” she said in a briefing held prior to her presentation of the data at the annual meeting of the American Society of Clinical Oncology.

“HER2 expression has been around a long time. We think about this all the time in breast cancer and drugs are approved there, but HER2 is expressed in other tumors as well, and that really represents an unmet need, because we have limited options in this situation” commented ASCO expert Bradley Alexander McGregor, MD, from the Dana-Farber Cancer Institute, Boston, an invited discussant at the briefing.

“Aside from pancreatic cancer we saw really, really encouraging results with no new safety signals, so while early I think this really exciting and represents a shift in how we think about cancer care,” he added.

After the presentation, invited discussant Kohei Shitara, MD, of National Cancer Center Hospital East, Kashiwa, Japan, said that he agrees with authors that T-DXd is a potential new treatment option for patients with HER2-expressing solid tumors, and that the evidence suggests the potential for further tumor-agnostic development of the agent.

He cautioned, however, that there is a lack of concordance between local and central assessment of HER2 IHC, and that quality assurance will be required to ensure that the HER2 status of solid tumors is accurately characterized.

At a press briefing, Dr. Meric-Bernstam was asked how she envisioned using T-DXd in therapy for various HER2-expressing tumors.

“I think the activity we’ve seen is quite compelling, and one hopes that eventually this will be a drug that’s accessible for patients that are HER2-expressing across tumor types. Clearly, the activity is very compelling in some of the diseases to think about doing studies for earlier lines,” she said.

“The data indicate that there is tumor-agnostic activity across the board,” she said, but noted that tumors with epithelial components such as ovarian and breast cancers appear to have the highest responses to T-DXd therapy.

Briefing moderator Julie R. Gralow, MD, chief medical officer and executive vice president of ASCO, asked Dr. McGregor whether, in the light of this new data, oncologists should test more patients for HER2 expression.

“We have some cancers where we know HER2 expression is there. I think the good thing about HER2 testing is that it’s an IHC test, so this is something that can be easily done in local pathology [labs],” he said. As more evidence mounts of potential benefit of T-DXd in HER2 expressing tumors, clinicians will need to consider more routine HER2 testing.
 

A rendezvous with DESTINY

The DESTINY-PanTumor02 trial is a phase 2, open-label, multicenter study looking at T-DXd in patients with advanced solid tumors who are not eligible for therapy with curative intent.

All patients had disease progression after at least two prior lines of therapy, and had tumors with HER2 expression of IHC 3+ or 2+ either by local or central testing. Patients were allowed to have previously received HER2-targeting therapy. Patients also had to have good performance status (Eastern Cooperative Oncology Group/World Health Organization performance status 0 or 1).

The investigators planned to enroll 40 patients in each cohort, including patients with cervical, endometrial, ovarian, biliary tract, pancreatic, or bladder cancers, as well those with other tumors expressing HER2 who were not included in the other cohorts.

Under the protocol, cohorts in which none of the first 15 patients had objective responses would be closed, as happened with the pancreatic cancer cohort.

At a median follow-up of 9.7 months, an objective response was seen in 99 patients out of the 267 in the entire study population (ORR, 37.1%). This ORR consisted of 15 complete responses and 84 partial responses. An additional 123 patients had stable disease.

An analysis of ORR by HER2 expression showed that IHC 3+ expressing tumors had rates ranging from 84.6% in endometrial cancers, 75% in cervical cancer, 63.6% in ovarian cancers, and 56.3% in bladder cancers, down to zero in IHC 3+ expressing pancreatic cancer. 

The T-DXd safety profile was consistent with that seen in other clinical trials, with most common adverse events being nausea, fatigue, neutropenia, anemia, diarrhea, and thrombocytopenia. There were 20 cases of interstitial lung disease, one of which was fatal.

The trial is ongoing, and investigators plan to report overall survival and progression-free survival results with additional follow-up.

DESTINY-PanTumor02 is funded by Daiichi Sankyo. Dr. Meric-Bernstam disclosed a consulting/advisory role with multiple pharmaceutical companies, research funding to her institution from Daiichi Sankyo and others, and travel expenses from ESMO and EORTC. Dr. McGregor disclosed a consulting/advisory role and institutional research funding with multiple companies, not including the study’s funder. Dr. Gralow disclosed a consulting or advisory role with Genentech and Roche.

CHICAGO – Fewer than 7% of patients newly diagnosed with cancer are tested for germline genetic mutations, and the percentage tested was even lower among racial and ethnic minorities, a huge study has found.

Information from germline genetic testing could affect a patient’s cancer care. For example, such testing could indicate that targeted therapies would be beneficial, and it would have implications for close relatives who may carry the same genes.

The finding that so few patients with newly diagnosed cancer were tested comes from an analysis of data on more than 1.3 million individuals across two U.S. states. The data were taken from the Surveillance, Epidemiology, and End Results (SEER) registry.

The rate is “well below guideline recommendations,” said study presenter Allison W. Kurian, MD, department of medicine, Stanford (Calif.) University.

“Innovative care delivery” is needed to tackle the problem, including the streamlining of pretest counseling, making posttest counseling more widely available, and employing long-term follow-up to track patient outcomes, she suggested.

“I do think this is a time for creative solutions of a number of different kinds,” she said. She suggested that lessons could be learned from the use of telemedicine during the COVID-19 pandemic. She also noted that “there have been some interesting studies on embedding genetic counselors in oncology clinics.”

Dr. Kurian presented the study at the annual meeting of the American Society of Clinical Oncology (ASCO). The study was simultaneously published in the Journal of the American Medical Association.

The current results represent a “missed opportunity for decrease the population-level burden of cancer,” experts noted in an accompanying editorial.

“Clinicians should recommend testing to their patients and provide them with the information necessary to make informed decisions about whether to undergo testing,” Zsofia K. Stadler, MD, and Deborah Schrag, MD, MPH, of Memorial Sloan Kettering Cancer Center, New York, wrote in their editorial.

They suggested novel approaches to widen access, such as use of point-of-care testing, telecounseling, and, in the future, chatbots to respond to patient questions.

“With greater emphasis on overcoming both health system and patient-level barriers to genetic cancer susceptibility testing for patients with cancer, treatment outcomes will improve and cancer diagnoses and related deaths in family members will be prevented,” they concluded.

At the meeting, invited discussant Erin Frances Cobain, MD, assistant professor of medical oncology, University of Michigan Health, Ann Arbor, referring to breast cancer as an example, said that progress has “stagnated” in recent years.

The study found a higher rate of gene testing among patients with newly diagnosed breast cancer, at just over 20%.

Dr. Cobain argued that this was still too low. She pointed out that “a recent study suggested that over 60% of individuals with an incident cancer diagnosis would meet criteria for genetic testing by National Comprehensive Cancer Network guidelines.

“This may be because testing is not offered, there may be poor access to genetic counseling resources, or patients may be offered testing but decline it,” she suggested.

One compelling reason to conduct genetic testing for patients newly diagnosed with breast cancer is that it may show that they are candidates for treatment with PARP (poly[ADP]-ribose polymerase) inhibitors, which “may have a direct impact on cancer-related mortality,” she pointed out.

“We need increased awareness and access to genetic testing resources for patients with breast cancer, particularly for racial and ethnic minorities,” she said.

Dr. Cobain also noted that finding variants of uncertain significance (VUS) was more likely among patients from racial and ethnic minorities than among White patients. She said such a finding “increases patient and physician anxiety,” and there may be “unclear optimal management recommendations for these patients.”
 

Details of the study

Germline genetic testing is “increasingly essential for cancer care,” Dr. Kurian said.

It is central to risk-adapted screening and secondary prevention, the use of targeted therapies, including PARP and checkpoint inhibitors, and cascade testing to identify at-risk relatives.

She pointed out that in clinical practice, testing has “evolved rapidly.” Panels include more and more genes. In addition, the cost of these tests is falling, and guidelines have become “more expansive.”

However, “little is known about genetic testing use and results,” Dr. Kurian noted.

The team therefore undertook the SEER-GeneLINK initiative, which involved patients aged ≥ 20 years who were diagnosed with cancer between Jan. 1, 2013, and March 31, 2019, and who were reported to statewide SEER registries in California and Georgia.

The team looked for patients for whom germline genetic test results had been reported by the four laboratories that performed the majority of patient testing in the two states. Results were categorized as pathogenic, benign, or VUS.

The results were classified on the basis of current guidelines for testing and/or management as related to breast/ovarian cancer, gastrointestinal cancer, other hereditary cancers, or those with no guidelines for testing or management.

Dr. Kurian reported that from an overall population of 1,412,388 patients diagnosed with cancer, 1,369,660 were eligible for inclusion. Of those, about half (51.9%) were women, and the majority (86.3%) were aged 50 years or older.

Many of these patients (61.4%) were non-Hispanic White persons, and slightly fewer than half (49.8%) were deemed to be in medium or high poverty, as determined using U.S. Census tract levels.

Overall, germline genetic testing was performed in 93,052 (6.8%) of patients over the study period.

Women were more likely to have undergone germline mutation testing than men, at 13.9% vs. 2.2%, as were patients aged 20-49 years, at 22.1% vs. 8.2% for those aged 50-69 years, and 3.3% for those aged 70 years and older.

The number of genes for which testing was conducted increased from a median of 2 in 2013 to 34 in 2019. Rates of VUS increased more than that for pathologic variants and substantially more so in non-White patients.

By 2019, the ratio of VUS to pathologic variants stood at 1.7 among White patients, vs. 3.9 among Asian patients, 3.6 among Black patients, and 2.2 among Hispanic patients.

The majority of identified pathologic variants that were related to the diagnosed cancer and genes with testing and/or management guidelines accounted for 67.5% to 94.9% of such variants.

Regarding specific cancer diagnoses, Dr. Kurian said that over the course of the study period, testing rates consistently exceeded 50% only among male breast cancer patients.

There were rapid increases in testing for ovarian cancer, from 28.0% of cases in 2013 to 54.0% in 2019. For pancreatic cancer, rates increased from 1.0% to 19.0% over the same period, and for prostate cancer, rates increased from 0.1% to 4.0%. She suggested that these increases in rates may be related to the approval of PARP inhibitors for use in these indications.

However, there was little change in the rates of germline mutation testing for lung cancer patients, from 01% in 2013 to 0.8% in 2019, and for other cancers, from 0.3% to 2.0%.

The results also revealed racial and ethnic differences in testing after controlling for age, cancer type, and year. Over the course of the study period, 8.0% of White patients underwent genetic testing, compared with 6.0% each for Asian, Black, and Hispanic patients and 5.0% for other patients (P < .001).

With regard specifically to male and female breast cancer and ovarian cancer, testing rates were 31% among White patients, 22% for Asian patients, 25% for Black patients, and 23% for Hispanic patients (P < .001).

Dr. Kurian acknowledged that the study is limited by a lack of testing from other laboratories and direct-to-consumer test data, although a recent survey suggested that this represents fewer than 5% of all germline genetic tests.

She also noted that the SEER registries do not collect data on family history or tumor sequencing.

The study was funded by the National Institutes of Health, and the Centers for Disease Control and Prevention. Dr. Kurian has relationships with Adela, Ambry Genetics, Color Genomics, GeneDx/BioReference, Genentech, InVitae, and Myriad Genetics. Other authors report numerous relationships with industry. Dr. Cobain has ties with AstraZeneca, Daiichi Sankyo, Athenex, Ayala Pharmaceuticals, bioTheranostics, and Immunomedics. Dr. Schrag has relationships with Merck, JAMA, AACR, and Grail. Dr. Stadler has ties with Adverum Biotechnologies, Genentech, Neurogene, Novartis, Optos Plc, Outlook Therapeutics, and Regeneron Pharmaceuticals.

CHICAGO – Fewer than 7% of patients newly diagnosed with cancer are tested for germline genetic mutations, and the percentage tested was even lower among racial and ethnic minorities, a huge study has found.

Information from germline genetic testing could affect a patient’s cancer care. For example, such testing could indicate that targeted therapies would be beneficial, and it would have implications for close relatives who may carry the same genes.

Oncology fellows who completed diversity, equity, and inclusion (DEI) training report that they feel more confident about responding to different types of discrimination, both when directed at them personally and when directed at others.

The finding comes from a survey conducted after the introduction of DEI training within the Yale Medical Oncology-Hematology Fellowship Program. The study was reported by Norin Ansari, MD, MPH, of Yale Cancer Center, New Haven, Conn., at the annual meeting of the American Society of Clinical Oncology (ASCO).

Dr. Ansari emphasized the DEI curriculum in fellowship programs by highlighting the racial and gender disparities that exist among physicians.

“There is a significant representation problem – only 2%-3% of practicing oncologists are Black or Hispanic/Latino,” she said. “And that representation decreases with each stage in the pipeline of the workforce.”

Dr. Ansari also noted gender disparities in the oncologist workforce, reporting that about one-third of faculty positions are held by women.

The anonymous survey was sent to 29 fellows; 23 responded, including 8 first-year fellows and 13 senior fellows. Over 57% of respondents rated the importance of DEI education as 10 on a 10-point scale (mean, 8.6).

At the start of this year, the responses of senior fellows who had already received some DEI training during the previous year’s lecture series were compared with first-year fellows who had not had any fellowship DEI education.

First-year fellows reported a mean confidence score of 2.5/5 at navigating bias and microaggressions when experienced personally and a mean score of 2.9/5 when they were directed at others. Senior fellows reported mean confidence scores of 3 and 3.2, respectively.

Yale then compared longitudinal data on fellows’ comfort levels in navigating discrimination in 2021, 2022, and 2023 a month before the ASCO meeting.

Fellows were asked to rate their comfort level from 1 to 10 in navigating different types of discrimination, including racial inequality, sexual harassment, and gender discrimination. In these three categories, fellows rated comfortability as a 5 in 2021 and as 7 in 2023 after the DEI training.

“Our first goal is to normalize talking about DEI and to recognize that different people in our workforce have different experiences and how we can be allies for them and for our patients,” Dr. Ansari said. “And I think for long-term goals we want to take stock of who’s at the table, who’s making decisions, and how does that affect our field, our science, and our patients.”

Yale designed the 3-year longitudinal curriculum with two annual core topics: upstander training and journal club for discussion and reflection. An additional two to three training sessions per year will focus on either race, gender, LGBTQ+, disability, religion, or implicit bias training.

The most popular topics among fellows were upstander training, cancer treatment and outcomes disparities, recruitment and retention, and career promotion and pay disparities.

The preferred platforms of content delivery were lectures from experts in the field, affinity groups or mentorship links, small group discussions, and advocacy education.

Gerald Hsu, MD, PhD, with the San Francisco VA Medical Center, discussed the results of Yale’s DEI curriculum assessment, saying it represented “best practices” in the industry. However, he acknowledged that realistically, not everyone will be receptive to DEI training.

Dr. Hsu said that holding medical staff accountable is the only way to truly incorporate DEI into everyday practice.

“Collectively, we need to be holding ourselves to different standards or holding ourselves to some standard,” Dr. Hsu said. “Maybe we need to be setting goals to the degree to which we diversify our training programs and our faculty, and there needs to be consequences to not doing so.”

No funding for the study was reported.

At the start of this year, the responses of senior fellows who had already received some DEI training during the previous year’s lecture series were compared with first-year fellows who had not had any fellowship DEI education.

First-year fellows reported a mean confidence score of 2.5/5 at navigating bias and microaggressions when experienced personally and a mean score of 2.9/5 when they were directed at others. Senior fellows reported mean confidence scores of 3 and 3.2, respectively.

Yale then compared longitudinal data on fellows’ comfort levels in navigating discrimination in 2021, 2022, and 2023 a month before the ASCO meeting.

Fellows were asked to rate their comfort level from 1 to 10 in navigating different types of discrimination, including racial inequality, sexual harassment, and gender discrimination. In these three categories, fellows rated comfortability as a 5 in 2021 and as 7 in 2023 after the DEI training.

“Our first goal is to normalize talking about DEI and to recognize that different people in our workforce have different experiences and how we can be allies for them and for our patients,” Dr. Ansari said. “And I think for long-term goals we want to take stock of who’s at the table, who’s making decisions, and how does that affect our field, our science, and our patients.”

Yale designed the 3-year longitudinal curriculum with two annual core topics: upstander training and journal club for discussion and reflection. An additional two to three training sessions per year will focus on either race, gender, LGBTQ+, disability, religion, or implicit bias training.

The most popular topics among fellows were upstander training, cancer treatment and outcomes disparities, recruitment and retention, and career promotion and pay disparities.

The preferred platforms of content delivery were lectures from experts in the field, affinity groups or mentorship links, small group discussions, and advocacy education.

Gerald Hsu, MD, PhD, with the San Francisco VA Medical Center, discussed the results of Yale’s DEI curriculum assessment, saying it represented “best practices” in the industry. However, he acknowledged that realistically, not everyone will be receptive to DEI training.

Dr. Hsu said that holding medical staff accountable is the only way to truly incorporate DEI into everyday practice.

“Collectively, we need to be holding ourselves to different standards or holding ourselves to some standard,” Dr. Hsu said. “Maybe we need to be setting goals to the degree to which we diversify our training programs and our faculty, and there needs to be consequences to not doing so.”

No funding for the study was reported.

On Nov. 22, three Food and Drug Administration inspectors arrived at the sprawling Intas Pharmaceuticals plant south of Ahmedabad, India, and found hundreds of trash bags full of shredded documents tossed into a garbage truck. Over the next 10 days, the inspectors assessed what looked like a systematic effort to conceal quality problems at the plant, which provided more than half of the U.S. supply of generic cisplatin and carboplatin, two cheap drugs used to treat as many as 500,000 new cancer cases every year.

Seven months later, doctors and their patients are facing the unimaginable: In California, Virginia, and everywhere in between, they are being forced into grim contemplation of untested rationing plans for breast, cervical, bladder, ovarian, lung, testicular, and other cancers. Their decisions are likely to result in preventable deaths.

Cisplatin and carboplatin are among scores of drugs in shortage, including 12 other cancer drugs, ADHD pills, blood thinners, and antibiotics. COVID-hangover supply chain issues and limited FDA oversight are part of the problem, but the main cause, experts agree, is the underlying weakness of the generic drug industry. Made mostly overseas, these old but crucial drugs are often sold at a loss or for little profit. Domestic manufacturers have little interest in making them, setting their sights instead on high-priced drugs with plump profit margins.

The problem isn’t new, and that’s particularly infuriating to many clinicians. President Joe Biden, whose son Beau died of an aggressive brain cancer, has focused his Cancer Moonshot on discovering cures – undoubtedly expensive ones. Indeed, existing brand-name cancer drugs often cost tens of thousands of dollars a year.

But what about the thousands of patients today who can’t get a drug like cisplatin, approved by the FDA in 1978 and costing as little as $6 a dose?

“It’s just insane,” said Mark Ratain, MD, a cancer doctor and pharmacologist at the University of Chicago. “Your roof is caving in, but you want to build a basketball court in the backyard because your wife is pregnant with twin boys and you want them to be NBA stars when they grow up?”

“It’s just a travesty that this is the level of health care in the United States of America right now,” said Stephen Divers, MD, an oncologist in Hot Springs, Ark., who in recent weeks has had to delay or change treatment for numerous bladder, breast, and ovarian cancer patients because his clinic cannot find enough cisplatin and carboplatin. Results from a survey of academic cancer centers released June 7 found 93% couldn’t find enough carboplatin and 70% had cisplatin shortages.

“All day, in between patients, we hold staff meetings trying to figure this out,” said Bonny Moore, MD, an oncologist in Fredericksburg, Virginia. “It’s the most nauseous I’ve ever felt. Our office stayed open during COVID; we never had to stop treating patients. We got them vaccinated, kept them safe, and now I can’t get them a $10 drug.”

The cancer clinicians KFF Health News interviewed for this story said that, given current shortages, they prioritize patients who can be cured over later-stage patients, in whom the drugs generally can only slow the disease, and for whom alternatives – though sometimes less effective and often with more side effects – are available. But some doctors are even rationing doses intended to cure.

Isabella McDonald, then a junior at Utah Valley University, was diagnosed in April with a rare, often fatal bone cancer, whose sole treatment for young adults includes the drug methotrexate. When Isabella’s second cycle of treatment began June 5, clinicians advised that she would be getting less than the full dose because of a methotrexate shortage, said her father, Brent.

“They don’t think it will have a negative impact on her treatment, but as far as I am aware, there isn’t any scientific basis to make that conclusion,” he said. “As you can imagine, when they gave us such low odds of her beating this cancer, it feels like we want to give it everything we can and not something short of the standard.”

Mr. McDonald stressed that he didn’t blame the staffers at Intermountain Health who take care of Isabella. The family – his other daughter, Cate, made a TikTok video about her sister’s plight – were simply stunned at such a basic flaw in the health care system.

At Dr. Moore’s practice, in Virginia, clinicians gave 60% of the optimal dose of carboplatin to some uterine cancer patients during the week of May 16, then shifted to 80% after a small shipment came in the following week. The doctors had to omit carboplatin from normal combination treatments for patients with recurrent disease, she said.

On June 2, Dr. Moore and colleagues were glued to their drug distributor’s website, anxious as teenagers waiting for Taylor Swift tickets to go on sale – only with mortal consequences at stake.

She later emailed KFF Health News: “Carboplatin did NOT come back in stock today. Neither did cisplatin.”

Doses remained at 80%, she said. Things hadn’t changed 10 days later.
 

Generics manufacturers are pulling out

The causes of shortages are well established. Everyone wants to pay less, and the middlemen who procure and distribute generics keep driving down wholesale prices. The average net price of generic drugs fell by more than half between 2016 and 2022, according to research by Anthony Sardella, a business professor at Washington University in St. Louis.

As generics manufacturers compete to win sales contracts with the big negotiators of such purchases, such as Vizient and Premier, their profits sink. Some are going out of business. Akorn, which made 75 common generics, went bankrupt and closed in February. Israeli generics giant Teva, which has a portfolio of 3,600 medicines, announced May 18 it was shifting to brand-name drugs and “high-value generics.” Lannett, with about 120 generics, announced a Chapter 11 reorganization amid declining revenue. Other companies are in trouble too, said David Gaugh, interim CEO of the Association for Accessible Medicines, the leading generics trade group.

The generics industry used to lose money on about a third of the drugs it produced, but now it’s more like half, Mr. Gaugh said. So when a company stops making a drug, others do not necessarily step up, he said. Officials at Fresenius Kabi and Pfizer said they have increased their carboplatin production since March, but not enough to end the shortage. On June 2, FDA Commissioner Robert Califf announced the agency had given emergency authorization for Chinese-made cisplatin to enter the U.S. market, but the impact of the move wasn’t immediately clear.

Cisplatin and carboplatin are made in special production lines under sterile conditions, and expanding or changing the lines requires FDA approval. Bargain-basement prices have pushed production overseas, where it’s harder for the FDA to track quality standards. The Intas plant inspection was a relative rarity in India, where the FDA in 2022 reportedly inspected only 3% of sites that make drugs for the U.S. market. Mr. Sardella testified in May that a quarter of all U.S. drug prescriptions are filled by companies that received FDA warning letters in the past 26 months. And pharmaceutical industry product recalls are at their highest level in 18 years, reflecting fragile supply conditions.

The FDA listed 137 drugs in shortage as of June 13, including many essential medicines made by few companies.

Intas voluntarily shut down its Ahmedabad plant after the FDA inspection, and the agency posted its shocking inspection report in January. Accord Healthcare, the U.S. subsidiary of Intas, said in mid-June it had no date for restarting production.

Asked why it waited 2 months after its inspection to announce the cisplatin shortage, given that Intas supplied more than half the U.S. market for the drug, the FDA said via email that it doesn’t list a drug in shortage until it has “confirmed that overall market demand is not being met.”

Prices for carboplatin, cisplatin, and other drugs have skyrocketed on the so-called gray market, where speculators sell medicines they snapped up in anticipation of shortages. A 600-mg bottle of carboplatin, normally available for $30, was going for $185 in early May and $345 a week later, said Richard Scanlon, the pharmacist at dr. Moore’s clinic.

“It’s hard to have these conversations with patients – ‘I have your dose for this cycle, but not sure about next cycle,’” said Mark Einstein, MD, chair of the department of obstetrics, gynecology and reproductive health at New Jersey Medical School, Newark.
 

Should government step in?

Despite a drug shortage task force and numerous congressional hearings, progress has been slow at best. The 2020 CARES Act gave the FDA the power to require companies to have contingency plans enabling them to respond to shortages, but the agency has not yet implemented guidance to enforce the provisions.

As a result, neither Accord nor other cisplatin makers had a response plan in place when Intas’ plant was shut down, said Soumi Saha, senior vice president of government affairs for Premier, which arranges wholesale drug purchases for more than 4,400 hospitals and health systems.

Premier understood in December that the shutdown endangered the U.S. supply of cisplatin and carboplatin, but it also didn’t issue an immediate alarm. “It’s a fine balance,” she said. “You don’t want to create panic-buying or hoarding.”

More lasting solutions are under discussion. Mr. Sardella and others have proposed government subsidies to get U.S. generics plants running full time. Their capacity is now half-idle. If federal agencies like the Centers for Medicare & Medicaid Services paid more for more safely and efficiently produced drugs, it would promote a more stable supply chain, he said.

“At a certain point the system needs to recognize there’s a high cost to low-cost drugs,” said Allan Coukell, senior vice president for public policy at Civica Rx, a nonprofit funded by health systems, foundations, and the federal government that provides about 80 drugs to hospitals in its network. Civica is building a $140 million factory near Petersburg, Va., that will produce dozens more, Mr. Coukell said.

Dr. Ratain and his University of Chicago colleague Satyajit Kosuri, MD, recently called for the creation of a strategic inventory buffer for generic medications, something like the Strategic Petroleum Reserve, set up in 1975 in response to the OPEC oil crisis.

In fact, Dr. Ratain reckons, selling a quarter-million barrels of oil would probably generate enough cash to make and store 2 years’ worth of carboplatin and cisplatin.

“It would almost literally be a drop in the bucket.”

In fact, Dr. Ratain reckons, selling a quarter-million barrels of oil would probably generate enough cash to make and store 2 years’ worth of carboplatin and cisplatin.

“It would almost literally be a drop in the bucket.”

CHICAGO – For the chief patient officer of the American Cancer Society, this year’s annual meeting of the American Society of Clinical Oncology was a gem. And it didn’t just sparkle because of the sequined Taylor Swift fans clogging the nearby streets during the meeting.

Arif Kamal, MD, MBA, MHS, who is also an oncologist at Duke University, Durham, N.C., said he was impressed by a pair of landmark studies released at the meeting that show hidden cancer can be targeted with “really remarkable outcomes.” He also highlighted sessions that examined the role of artificial intelligence (AI) in oncology, during an interview.

Below are lightly edited excerpts from a conversation with Dr. Kamal:



Question: What are some of most groundbreaking studies released at ASCO?

Answer: One is an interim analysis of the NATALEE trial, which involved patients with early-stage hormone receptor-positive, HER2-negative (HR+/HER2–) breast tumors. This phase 3 randomized trial compared maintenance therapy with the cyclin-dependent kinase 4/6 (CDK4/6) inhibitor ribociclib (Kisqali) plus endocrine therapy with an aromatase inhibitor to endocrine therapy alone in patients with node-positive or node-negative and stage II or III HR+/HER– breast cancer.

For a long time, the standard care in these patients has been to use endocrine therapy alone. This is the first big trial to show that upstream usage of additional therapy in early stages is also beneficial for disease-free survival. The 3-year invasive disease-free survival rate was 90.4% in the rebociclib-endocrine therapy group vs. 87.1% for patients who received only endocrine therapy (P = .0014).



Q: How do these findings add to current knowledge?

A: Typically, we let people get metastatic disease before we use CDK4/6 inhibitors. These findings show that systemic treatment beyond endocrine therapy will be helpful in cases where you’ve got smaller disease that has not spread yet.

Even in patients with node-negative breast cancer, micrometastatic disease is clearly there, because the medication killed the negative lymph nodes.



Q: What else struck you as especially important research?

A: The NATALEE findings match what we saw in another study – the ADAURA trial, which looked at adjuvant osimertinib in non–small-cell lung cancer patients with EGFR-mutated, stage IB to IIIA disease – cancer that has not spread to the lymph nodes.

This is another example where you have a treatment being used in earlier-stage disease that’s showing really remarkable outcomes. The study found that 5-year overall survival was 88% in an osimertinib group vs. 78% in a placebo group (P < .001). This is a disease where, in stage IB, we wouldn’t even necessarily give these patients treatment at all, other than surgical resection of the tumor and maybe give them a little bit of chemotherapy.

Even in these smaller, early tumors, osimertinib makes a difference.



Q: As a whole, what are these studies telling us about cancer cells that can’t be easily detected?

A: To find a disease-free survival benefit with adding ribociclib in a stage II, stage III setting, particularly in node-negative disease, is remarkable because it says that the cells in hiding are bad actors, and they are going to cause trouble. The study shows that medications can find these cells and reverse that risk of bad outcomes.

If you think about the paradigm of cancer, that’s pretty remarkable because the ADAURA trial does the same thing: You do surgery for [early-stage] lung cancers that have not spread to the lymph nodes and you figure, “Well, I’ve got it all, right? The margins are real big, healthy, clean.” And yet, people still have recurrences, and you ask the same question: “Can any medicine find those few cells, the hundreds of cells that are still left somewhere in hiding?” And the answer is again, yes. It’s changing the paradigm of our understanding of minimal residual disease.

That’s why there’s so much interest in liquid biopsies. Let’s say that after treatment we don’t see any cancer radiologically, but there’s a signal from a liquid biopsy [detecting residual cancer]. These two trials demonstrate that there’s something we can do about it.



Q: There were quite a few studies about artificial intelligence released at ASCO. Where do we stand on that front?

A: We’re just at the beginning of people thinking about the use of generative AI for clinical decision support, clinical trial matching, and pathology review. But AI, at least for now, still has the issue of making up things that aren’t true. That’s not something patients are going to be okay with.



Q: How can AI be helpful to medical providers considering its limitations?

A: AI is going to be very good at the data-to-information transition. You’ll start seeing people use AI to start clinical notes for them and to match patients to the best clinical trials for them. But fundamentally, the clinician’s role will continue to be to check facts and offer wisdom.



Q: Will AI threaten the careers of oncologists?

A: The body of knowledge about oncology is growing exponentially, and no one can actually keep up. There’s so much data that’s out there that needs to be turned into usable information amid a shortage of oncologists. At the same time, the prevalence of cancer is going up, even though mortality is going down.

Synthesis of data is what oncologists are waiting for from AI. They’ll welcome it as opposed to being worried. That’s the sentiment I heard from my colleagues.

In metastatic breast cancer, a fixed dose of capecitabine given on a 7-day-on, 7-day-off schedule had similar efficacy and reduced adverse events compared with the standard 14-day-on, 7-day-off schedule, in a new study.

Both progression-free survival (PFS) and overall survival (OS) were similar between the two groups, but patients on the alternative schedule experienced fewer cases of hand-foot syndrome (HFS), diarrhea, and stomatitis, and also had fewer discontinuations and dose modifications.

The Food and Drug Administration–approved dose of capecitabine is 1,250 mg/m², but 14 days of treatment can lead to significant toxicity, said Qamar Khan, MD, during a presentation of the study at the annual meeting of the American Society of Clinical Oncology. “Mathematical models applied to xenograft [animal model] data suggest that the maximum cytotoxic effect of capecitabine occurs after about 7 days of treatment, beyond which time only toxicity increases,” Dr. Khan said during his talk on the randomized control trial.

The researchers randomized 153 patients to receive a fixed 1,500-mg capecitabine dose twice per day on a 7-day-on, 7-day-off schedule (7/7), or the 1,250–mg/m² dose twice per day for 14 days followed by 7 days off (14/7). The median age was 60 years, and 85.6% were White, 8.5% were African American, 3.3% were Hispanic, 0.7% were American Indian or Alaskan Native, and 2.0% were other. With respect to disease characteristics, 44% had visceral metastasis, 78% were hormone receptor positive/HER2 negative, and 11% had triple-negative breast cancer. About two-thirds (65%) had received no prior chemotherapy.

Restricted mean survival time (RMST) at 36 months for PFS was 13.9 months in the 7/7 group and 14.6 months in the 14/7 group (difference, 0.7 months; 95.5% CI, –3.14 to 4.57 months). The objective response rate was 8.9% in the 7/7 group and 19.6% in the 14/7 group (P = .11). Median OS was 19.8 months in the 7/7 group and 17.5 months in the 14/7 group (hazard ratio, 0.76; P = .17). The RMST at 47 months for OS was 24.5 months in the 7/7 group and 20.9 months in the 14/7 group (difference, –3.6 months; 95% CI, –8.89 to 1.54 months).

The researchers found no differences in subgroup analyses by visceral metastasis, breast cancer subtype, or number of lines of previous therapy.

The toxicity profile of 7/7 was better with respect to grade 2-4 diarrhea (2.5% vs. 20.5%, P = .0008), grade 2-4 HFS (3.8% vs. 15.1%; P = .0019), and grade 2-4 mucositis (0% vs. 5.5%; P =.0001).
 

Findings back up clinical practice

“The fixed-dose capecitabine dosing is something that’s been done a lot in practice, because a lot of practitioners recognize that giving the drug for two weeks in a row with a week break is overly toxic, so it’s something we’ve been doing in the community for quite a while,” said Michael Danso, MD, who comoderated the session.

Still, the safety and efficacy data back up that general clinical practice. “There was a randomized trial and colon cancer that didn’t show [equivalent outcomes with the alternate dosing schedule]. So to see that it’s safe and effective in breast cancer is an important [finding],” said Dr. Danso, who is the Research Director at Virginia Oncology Associates, Norfolk.

During the question-and-answer following the talk, Jeffrey Kirshner, MD, a medical oncologist at Hematology-Oncology Associates of Central New York, East Syracuse, noted that his practice has used a similar schedule for years. “I really commend you for doing that study. It really supports what many of us in the real world have been doing for many years. We figured this out empirically, both upfront and when patients can’t tolerate [the 14/7 schedule].”
 

Fixed dose versus body surface area

Dr. Kirshner also said his practice uses a dose of 1 g/m² of body surface area on a 7/7 schedule rather than a fixed dose as was done in Dr. Khan’s study. “If you use the higher dose, you might have seen a higher response rate because many of our patients, as you know, have a body surface [BSA] area much greater than 1.5 g/m².”

Dr. Khan responded that there is little data available on BSA dosing. “We selected 1,500 mg because a lot of people are practicing that, and for convenience, and that most patients who started at a higher dose eventually wound up on a dose of 1,500 mg twice daily.”

Dr. Kirshner also pointed out that the study was conducted in a population with metastatic disease. “I think we need to emphasize that we do not use the 7/7 regimen in a potentially curative setting, such as the CREATE-X regimen for triple-negative [breast cancer].”

Dr. Khan agreed. “I would use the same dose as the CREATE-X trial in the adjuvant setting,” he responded.

Triple-negative breast cancer (TNBC) is characterized by the absence of hormonal receptors and human epidermal growth factor receptor 2 (HER2) expression. Historically, treatments targeting HER2 were found to be ineffective in patients with TNBC and known HER2-zero status. Researchers more recently identified a new type of TNBC involving patients with low expression of HER2. Patients with this type of breast cancer, now referred to as HER2-low, have immunohistochemical (IHC) analysis scores of 1+ or 2+ and negative in situ hybridization (ISH) stain.

In a new study, patients with TNBC who initially tested as having HER2-zero status were later found to have HER2-low status following repeated biopsies. These HER2-low results were of great clinical significance for this patient population, said Yael Bar, MD, PhD, during her presentation of the research, at the annual meeting of the American Society of Clinical Oncology (ASCO).

Previously, the DESTINY-Breast04 trial demonstrated that the antibody-drug conjugate (ADC) trastuzumab deruxtecan (T-DXd) improved progression-free survival (PFS) and overall survival (OS) for patients with HER2-low metastatic breast cancer. “As a result [of the DESTINY-Breast04 findings], T-DXd is now approved for HER2-low but not HER2-zero triple-negative metastatic breast cancer."

“While HER2-low is detected in about 30%-50% of patients with triple-negative breast cancer, several studies have shown that HER2 status is heterogeneous and also dynamic over time, said Dr. Bar, who is an international research fellow in the breast cancer group at Mass General Cancer Center, Boston.

In the new study, Dr. Bar and her co-authors retrospectively identified 512 TNBC patients from 2000 to 2022 from an institutional database. They included core, surgical, or metastatic biopsies. Participants had a mean age of 52 years, with 54% over age 50. They were 83% White, 7% African American, 5% Asian, 3% Hispanic, and 2% other. Stage II was most common at diagnosis at 48%, followed by stage 1 (28%), stage 3 (14%), and stage IV (8%).

Most patients had undergone one (38%) or two (45%) biopsies, while 9% underwent three biopsies, 6% underwent four biopsies, and 2% underwent five or more.

Among all 512 patients in the study, 60% had a HER2-low result on their first biopsy. As of the second biopsy, 73% had at least one HER2-low result, with 13% of the first HER2-low results occurring at the second biopsy. As of the third biopsy, 81% had a HER2-low result, with 9% occurring for the first time. At the fourth biopsy, 86% had a positive result, with 8% occurring for the first time. All patients with five or more biopsies had at least one HER2-low result and none were first-time results.

At the second biopsy, a HER2-low result was detected for 32% of patients for the first time. At the third biopsy, a new HER2-low result was detected in 33%, and at the fourth biopsy, a new HER-2 result was detected in 38%.

The researchers matched early and metastatic biopsies in 71 patients, and 44% had changed status: 68% of those with a status change went HER2-low to HER2-zero, 26% from HER2-zero to HER2-low, and 6% from HER2-low to HER2-positive. Among 50 patients with matched metastatic biopsies, 33% had a change in status, with 63% going from HER2-zero to HER2-low, 31% from HER2-low to HER2-zero, and 6% from HER2-low to HER2-positive.

“We showed here that repeat biopsies can identify new HER2-low results for patients who were previously ineligible for T-DXd; and therefore, we think that a repeat biopsy could be considered if feasible and safe. Also, if a repeat biopsy is performed for any reason, but mainly upon metastatic recurrence, receptors should be retested,” said Dr. Bar.

After Dr. Bar’s presentation, Barbara Pistilli, MD served as a discussant. She noted the increased HER2-low results over successive biopsies. “However, here the question is, are these results related to the changes in the analytical methods over the past 20 years or the changes in the guidelines in terms of definition of HER2 status, or are they more related to a true evolution of HER2 status with the evolution of the disease?” she said during her presentation. Dr. Pistilli is chair of the breast disease committee at Gustave Roussy in Villejuif, France.

She also said that HER2 expression can vary even between different parts of the same tumor and called for alternative methods to following HER2 expression. “I don’t think that we can follow our patients with multiple biopsies over the disease evolution, so we have to find other tools, such as target-positive [circulating tumor cells], or antibody-radiolabeled PET scan in order to better follow the intermetastasis target heterogeneity over time, and finally define what is the optimal ADC sequential strategy for each patient,” said Dr. Pistilli.

Comoderator Michael Danso, MD, also weighed in when asked for comment. 

“It was an important trial to show that serial biopsies potentially allow more patients to receive trastuzumab deruxtecan,” said Dr. Danso, who is the research director at Virginia Oncology Associates, Norfolk. However, he pointed out the concerns of a statistician who had spoken up during the question-and-answer session who said that the positive results could simply be the consequence of repeated testing. “If you do a test often enough, statistically you’re going to get a difference in outcome. That was an important point made. Also, if you’re going to get 100% of patients who are eventually going to [develop HER2-low status], the question is, can you just treat everybody with trastuzumab deruxtecan and not do these sequential biopsies? Obviously that is subject to cost; it’s subject to toxicity as well, so you probably want documentation that there is a HER2-low result,” said Dr. Danso.

Dr. Bar has no relevant financial disclosures. Dr. Pistilli has consulted for or advised AstraZeneca, Daiichi Sankyo/UCB Japan, Myriad Genetics, Novartis, PIERRE FABRE, and Puma Biotechnology. She has received research funding through her institution from AstraZeneca, Daiichi Sankyo, Gilead Sciences, Merus, Pfizer, and Puma Biotechnology.

Shortages of carboplatin and cisplatin have become widespread among major cancer centers, according to a survey released this week from the National Comprehensive Cancer Network.

The survey, which included responses from 27 NCCN member institutions, revealed that 93% are experiencing a shortage of carboplatin and that 70% have reported a shortage of cisplatin.

“This is an unacceptable situation,” Robert W. Carlson, MD, NCCN’s chief executive offer, said in the statement released by the network.

“We are hearing from oncologists and pharmacists across the country who have to scramble to find appropriate alternatives for treating their patients with cancer right now,” Dr. Carlson said. And while the survey results show patients are still able to get lifesaving care, “it comes at a burden to our overtaxed medical facilities.”

The NCCN called on the federal government, the pharmaceutical industry, providers, and payers to take steps to “help mitigate any impacts” from this cancer drug shortage.

“We need to work together to improve the current situation and prevent it from happening again in the future,” Dr. Carlson stressed.

Carboplatin and cisplatin, which are frequently used together for systemic treatment, are highly effective therapies prescribed to treat many cancer types, including lung, breast, and prostate cancers, as well as leukemias and lymphomas. An estimated 500,000 new patients with cancer receive these agents each year.

The current survey, conducted over the last week of May, found that 100% of responding centers are able to continue to treat patients who need cisplatin without delays.

The same cannot be said for carboplatin: only 64% of centers said they are still able to continue treating all current patients receiving the platinum-based therapy. Among 19 responding centers, 20% reported that they were continuing carboplatin regimens for some but not all patients. And 16% reported treatment delays from having to obtain prior authorization for modified treatment plans, though none reported denials.

“Carboplatin has been in short supply for months but in the last 4 weeks has reached a critical stage,” according to one survey comment. “Without additional inventory many of our sites will be out of drug by early next week.”

In response to the survey question, “Is your center experiencing a shortage of carboplatin,” others made similar comments:

• “Current shipments from established manufacturers have been paused.”
• “The supply of carboplatin available is not meeting our demands.”
• “Without additional supply in early June, we will have to implement several shortage mitigation strategies.”

Survey respondents also addressed whether manufacturers or suppliers have provided any indication of when these drugs will become readily available again. For both drugs, about 60% of respondents said no. And for those who do receive updates, many noted that the “information is tentative and variable.”

Respondents indicated that other cancer agents, including methotrexate (67%) and 5FU (26%), are also in short supply at their centers.

The shortage and the uncertainty as to when it will end are forcing some centers to develop conservation and mitigation strategies.

The NCCN has broadly outlined how the federal government, the pharmaceutical industry, providers, and payers can help with prevention and mitigation. The NCCN has called on the federal government and the pharmaceutical industry to work to secure a steady supply of core anticancer drugs and has asked payers to “put patients first and provide flexible and efficient systems of providing coverage for alternative therapies replacing anti-cancer drugs that are unavailable or in shortage.”

Overall, the survey results “demonstrate the widespread impact of the chemotherapy shortage,” said Alyssa Schatz, MSW, senior director of policy and advocacy for NCCN. “We hope that by sharing this survey and calling for united action across the oncology community, we can come together to prevent future drug shortages and ensure quality, effective, equitable, and accessible cancer care for all.”

The combination of ribociclib (Kisqali) and endocrine therapy has already been shown to yield a significant survival advantage for women with metastatic, hormone receptor–positive, HER2-negative (HR+/HER2–) breast cancer. Now the same combination has also shown benefit in early-stage HR+/HER2– breast tumors.

The new results come from an interim analysis of the phase 3, randomized NATALEE trial, which is comparing maintenance therapy with the (CDK4/6 inhibitor ribociclib plus endocrine therapy with an aromatase inhibitor to endocrine therapy alone.

At a median follow-up of 27.7 months, the 3-year invasive disease–free survival (IDFS) rate was 90.4% for patients who received the combination, compared with 87.1% for patients who received endocrine therapy alone.

This difference translates into a 25% relative reduction in risk for recurrence with the addition of ribociclib, said principal investigator Dennis J. Slamon, MD, PhD, from the UCLA Jonsson Comprehensive Cancer Center, Los Angeles.

“The NATALEE results, in summary, do support this as a new treatment of choice available to physicians and patients for this broad population of patients with stage II or stage III hormone receptor–positive, HER2-negative disease in early breast cancer,” he said.

Dr. Slamon was speaking at a media briefing held prior to the annual meeting of the American Society of Clinical Oncology, where the results were presented
 

‘Early but impressive’

“Today, Dr. Slamon has shown us early but impressive data demonstrating a significant reduction in the risk of recurrence as defined by an improvement of invasive disease–free survival for patients with high-risk, node-positive and node-negative hormone receptor–positive, HER2-negative early breast cancer,” commented ASCO expert Rita Nanda, MD, director of the breast oncology program at the University of Chicago.

“We know that a substantial proportion of patients with early-stage hormone receptor–positive breast [cancer] can go on to recur,” Dr. Nanda continued. “These recurrences can be quite delayed, and for our patients with node-negative disease, to this point, we haven’t seen any improvements with the addition of a CDK4/6 inhibitor to endocrine therapy for early-stage breast cancer. Dr Slamon has also shown us that ribociclib in the context of the NATALEE trial is effective, it was well tolerated, and I do expect that these trial results will change practice.”

In a comment, Sylvia Adams, MD, a medical oncologist who specializes in breast cancer at the NYU Langone Perlmutter Cancer Center, New York, said she is comfortable with using a CDK4/6 inhibitor such as ribociclib or abemaciclib (Verzenio) in the adjuvant setting for patients with early, localized breast cancer.

She noted, however, that to date the absolute benefit of the combination over endocrine therapy alone has been modest, at 3.3%, but that the difference may be important to many patients who feel that they need to do everything they can to prevent disease recurrence.

“I’m really looking forward to the quality of life data, because it’s certainly known that any of these CDK4/6 inhibitors may add a bit of fatigue, and while there were no unexpected safety signals [in NATALEE], we know that there are some GI [gastrointestinal] effects with this therapy, as well as joint pain,” she said. “Joint pain is a little tricky, because the patients are also getting aromatase inhibitors, which can cause joint pain.”

In addition, premenopausal women in the study also received goserelin, an ovarian suppressor that triggers menopause, which is also associated with arthralgias, Dr. Adams said.

Dr. Adams and Dr. Nanda both noted that the addition of ribociclib to endocrine therapy increases the treatment burden for patients because it requires a commitment of at least 3 years and more frequent monitoring, especially in the first few months of therapy, compared with endocrine therapy alone.
 

Study details

The combination of ribociclib and standard of care endocrine therapy was the first to show an improvement in overall survival among women with metastatic HR+/HER2– breast cancer.

To see whether the combination could also benefit patients with early breast cancer, the investigators conducted NATALEE. They enrolled premenopausal and postmenopausal women and also men with HR+/HER2– breast cancer. Cases ranged from stage IIA (with either no nodal involvement with additional risk factors or with one to three involved axillary lymph nodes) to stage IIB-III disease, based on American Joint Committee on Cancer staging.

Patients who had previously received neoadjuvant or adjuvant endocrine therapy were accepted into the trial if the therapy had been started within 1 year of randomization.

The patients were stratified by age, menopausal status, disease stage, prior chemotherapy status, and geographic region. They were randomly assigned to receive either ribociclib 400 mg per day for 3 weeks, then were given 1 week off each cycle for 3 years plus endocrine therapy with either letrozole 2.5 mg/day or anastrozole 1 mg/day for at least 5 years, or to endocrine therapy alone. Men and premenopausal women also received goserelin.

Dr. Slamon noted that the 400-mg dose of ribociclib is lower than the recommended starting dose of 600 mg for metastatic disease. They chose the lower dose to allow longer duration of therapy, with a goal of achieving optimal disease suppression by driving tumor cells into irreversible senescence with less side effects.

A total of 2,549 patients were randomly assigned to receive the combination; 2,552 patients received endocrine therapy alone.

At the data cutoff on Jan. 11, 2023, after the prespecified minimum number of IDFS events had occurred, 189 patients in the ribociclib arm experienced recurrence, compared with 237 patients in the endocrine therapy–only arm.

As noted, 3-year IDFS rates were 90.4% with ribociclib and 87.1% with endocrine therapy alone, which translates to a hazard ratio of 0.748 in favor of the combination (P = .0014).

The benefit of ribociclib was generally consistent across subgroups, including node-negative patients, but there were too few patients in this subgroup for the differences to reach statistical significance, Dr. Slamon said.
 

Safety

The most commonly reported adverse event in the endocrine therapy–alone arm were joint pain and hot flashes

The most common adverse events with ribociclib included neutropenia and joint pain. Rates of gastrointestinal adverse events and fatigue, typical of CDK4/6 inhibitors, were relatively low in this study.

Dr. Slamon compared the rates of neutropenia with ribociclib in this trial to those in pooled data from the MONALEESA series of trials, in which ribociclib was delivered at a 600-mg dose. Grade 3 or 4 neutropenia occurred in 44% of patients in NATALEE, compared with 60% of patients in the MONALEESA trials.

In the ribociclib arm, 5.2% of patients experienced prolongation of the QT interval, compared with 1.2% of patients in the endocrine therapy–alone arm. No cases of torsades des pointes or problematic rhythm disturbances were observed, Dr. Slamon said.

“As frequently happens when we have these lovely, large, phase 3 registration trials but with some restriction in eligibility, when you get out to real-world practice, we don’t know what will happen in women who are on antiarrhythmics and if they’ll have a higher incidence of the QT elongation; they just weren’t included in the study. So it sounds like we’ll have to be paying attention to that,” commented briefing moderator Julie R. Gralow, MD, FACP, FASCO, chief medical officer and executive vice president of ASCO.

The study was funded by Novartis. Dr. Slamon has a leadership position with 1200 Pharma, Biomarin, and Torl Biotherapeutics, a consulting/advisory role for Novartis, and has received honoraria, research funding, and travel expenses from Novartis and others. Multiple coauthors reported financial relationships with Novartis and others. Dr. Nanda has had consulting/advisory roles with and has received institutional research funding from several companies, not including Novartis. Dr. Adams has participated on an advisory board for Cogent Biosciences and her institution has received research funding from various companies.

The combination of ribociclib (Kisqali) and endocrine therapy has already been shown to yield a significant survival advantage for women with metastatic, hormone receptor–positive, HER2-negative (HR+/HER2–) breast cancer. Now the same combination has also shown benefit in early-stage HR+/HER2– breast tumors.

The new results come from an interim analysis of the phase 3, randomized NATALEE trial, which is comparing maintenance therapy with the (CDK4/6 inhibitor ribociclib plus endocrine therapy with an aromatase inhibitor to endocrine therapy alone.

At a median follow-up of 27.7 months, the 3-year invasive disease–free survival (IDFS) rate was 90.4% for patients who received the combination, compared with 87.1% for patients who received endocrine therapy alone.

This difference translates into a 25% relative reduction in risk for recurrence with the addition of ribociclib, said principal investigator Dennis J. Slamon, MD, PhD, from the UCLA Jonsson Comprehensive Cancer Center, Los Angeles.

“The NATALEE results, in summary, do support this as a new treatment of choice available to physicians and patients for this broad population of patients with stage II or stage III hormone receptor–positive, HER2-negative disease in early breast cancer,” he said.

Dr. Slamon was speaking at a media briefing held prior to the annual meeting of the American Society of Clinical Oncology, where the results were presented
 

‘Early but impressive’

“Today, Dr. Slamon has shown us early but impressive data demonstrating a significant reduction in the risk of recurrence as defined by an improvement of invasive disease–free survival for patients with high-risk, node-positive and node-negative hormone receptor–positive, HER2-negative early breast cancer,” commented ASCO expert Rita Nanda, MD, director of the breast oncology program at the University of Chicago.

“We know that a substantial proportion of patients with early-stage hormone receptor–positive breast [cancer] can go on to recur,” Dr. Nanda continued. “These recurrences can be quite delayed, and for our patients with node-negative disease, to this point, we haven’t seen any improvements with the addition of a CDK4/6 inhibitor to endocrine therapy for early-stage breast cancer.
