Updates from Industry

The clinical trial field is always changing, bringing new treatments and new clinical trial opportunities to the table. From our industry partners, we have selected some key updates in the world of breast cancer treatments and want to she these updates with you.

 

February 2024:

  • Chimeric antigen receptor (CAR) T cell therapies are a big topic lately, especially in oncology fields where precision approaches in treatment are necessary. With CAR-T cell treatments, T cells are taken from the patient and modified to be able to recognize and attack specific patterns found only in the cells being targeted, like cancer cells. These modified T cells are then given back to the patient where they can attack only the targeted cancer cells. Currently, CAR-T cell therapy has shown success with this approach and one treatment developed by Novartis and the University of Pennsylvania has been FDA-approved to treat blood cancers like acute lymphoblastic leukemia (ALL); this approach is currently in development for the treatment of solid tumors like breast cancer. This type of treatment is currently being studied at research institutions like City of Hope in Duarte, California, where an ongoing study examines how these genetically engineered T cells can be designed to target and destroy HER2+ cancer cells. Additional ongoing studies examine potential targets for CAR-T cells in the treatment of triple negative breast cancer (TNBC), a breast cancer subtype that is notoriously difficult to target due to the lack of typical receptor targets such as HER2, ER, and PR. After positive results in early studies, a research team at Penn is planning a clinical trial that will study use of CAR-T cells in clearing residual tumor cells that may remain after surgical resection. 
  • Genomic diagnostic tests that can help physicians decide on the most effective therapies for specific breast cancer subtypes are becoming more specialized as new testing approaches are developed and paired together. The Breast Cancer Index® is a test that provides an individual assessment for those with hormone receptor-positive subtypes that can determine whether or not extended anti-estrogen therapy will be beneficial. Similarly, the HER2DX® test looks at biomarkers for several different genes and biological processes in individuals with early stage HER2+ breast cancer and can provide insight on the probability of response for several therapies. This type of diagnostic test can also be used to identify early cases of breast cancer as an addition to existing screening procedures, as highlighted in the coming INTERCEPT clinical trial which examines cancer biomarkers using a less-invasive liquid biopsy procedure rather than a typical tumor biopsy.

December 2023:

  • In November, the FDA approved the combination of capivasertib (Truqap, AstraZeneca Pharmaceuticals) and fulvestrant for patients with metastatic or locally advanced HR+, HER2- breast cancer that is positive for PIK3CA/AKT1/PTEN biomarker alterations. At the same time, the FDA also approved a new test designed to identify these specific biomarker alterations in order to assess whether patients should consider this new treatment combination. In the clinical trial that compared this combination versus fulvestrant without capivasertib, progression-free survival rates doubled in the group of patients that received both treatments together.

  • The American Cancer Society’s Blue-button Project team, supported by Amgen, has recently published several articles discussing ways to better match patients to clinical trials. One article demonstrates use of an automated screening tool that reviews electronic health records and compares with eligibility criteria for regionally-located clinical trials, finding trials for 91% more patients than traditional approaches. Another article recommends changes in policy, staffing, and procedures that could better support the opportunity to match eligible patients with trials. Lastly, the third article reviews existing methods for trial matching and identifies both challenges and solutions within through direct interviews with healthcare providers involved in clinical research.

  • The White House Office of Science and Technology Policy is leading a new project to improve the way clinical trials are designed and managed. The Clinical Trials Readiness Initiative will support more inclusive clinical trials and will make them simpler and more accessible to all. Roundtables and listening sessions were held to capture unmet needs that this initiative is designed to address. The top-listed action for this initiative is to enable more diverse participation in clinical trials; to achieve this, more diverse workforces will be needed at hospitals and clinics and increased community outreach and education opportunities will come into play. Many other groups are partnering together on this project to ensure it’s plans can be met. In the long run, this initiative aims to increase distribution of trial sites to areas with minimal existing opportunities, to increase diverse participation in clinical research, to simplify study design for care providers and trial participants, and to better engage with communities in order to establish the trust necessary to support clinical research.

October 2023:

  • AstraZeneca announced the US Food and Drug Administration (FDA) has granted Priority Review for their investigational combination therapy for the treatment of adult patients with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative locally advanced or metastatic breast cancer following recurrence or progression on or after an endocrine-based regimen. The new drug application is based on data from the CAPItello-291 Phase III trial presented at the 2022 San Antonio Breast Cancer Symposium and recently published online in The New England Journal of Medicine. For more information regarding this announcement, please see AstraZeneca’s press release.   
  • Daiichi-Sankyo announced that the U.S. Food and Drug Administration (FDA) has approved ENHERTU®(fam-trastuzumab deruxtecan-nxki) for the treatment of adult patients with unresectable or metastatic HER2-low (IHC 1+ or IHC 2+/ISH-) breast cancer who have received a prior chemotherapy in the metastatic setting or developed disease recurrence during or within six months of completing adjuvant chemotherapy. This approval makes ENHERTU the first approved HER2-directed therapy for patients with low levels of HER2 expression. The approval by the FDA is based on the results of the historic DESTINY-Breast04 clinical trial presented at ASCO. Targeting this lower range of expression in the HER2 spectrum offers another approach to delay disease progression and extend survival in patients with metastatic breast cancer.

  • Novartis recently shared data from their NATALEE trial, examining Kisqali® (ribociclib) in HR-positive, HER2-negative early breast cancer. Kisqali is the first and only CDK4/6 inhibitor to demonstrate a consistent, clinically meaningful benefit across a broad population of patients with HR+/HER2- early breast cancer, regardless of disease stage, menopausal or nodal status. Results were also consistent across all secondary endpoints, including distant disease-free survival and recurrence-free survival, with a trend for improved overall survival. The safety profile of Kisqali was favorable at 400 mg with low rates of symptomatic adverse events and limited treatment modifications when administered up to three years. Collectively, NATALEE results have the potential to more-than-double the number of patients who could benefit from treatment with a CDK4/6 inhibitor in the adjuvant setting. Novartis plans to submit these Phase III data to regulatory authorities in the US and Europe before end of year. For more information from Novartis, please click here.
