FDA Approves Ibrance (palbociclib) for the Treatment of Men with HR+, HER2- Metastatic Breast Cancer

By | April 8, 2019

April 4, 2019 — Pfizer (NYSE:PFE) today announced that the U.S. Food and Drug Administration (FDA) approved a supplemental New Drug Application (sNDA) to expand the indications for Ibrance (palbociclib) in combination with an aromatase inhibitor or fulvestrant to include men with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) advanced or metastatic breast cancer. The approval is based on data from electronic health records and postmarketing reports of the real-world use of Ibrance in male patients sourced from three databases: IQVIA Insurance database, Flatiron Health Breast Cancer database and the Pfizer global safety database.

“With this approval, we are now able to offer Ibrance to the underserved male breast cancer community and provide more patients with HR+, HER2- metastatic breast cancer the opportunity to access an innovative medicine,” said Chris Boshoff, M.D., Ph.D., Chief Development Officer, Oncology, Pfizer Global Product Development. “We appreciate that our partnership with the FDA has allowed us to take a significant step forward in the use of real-world data to bring medicines to patients who are most in need.”

Ibrance is now approved for adult patients with HR+, HER2- advanced or metastatic breast cancer in combination with an aromatase inhibitor as initial endocrine based therapy in postmenopausal women or in men; or with fulvestrant in patients with disease progression following endocrine therapy. With today’s approval, Ibrance is the first and only CDK 4/6 inhibitor indicated in combination with an aromatase inhibitor for the first-line treatment of men with HR+, HER2- metastatic breast cancer in the U.S.

“Men with breast cancer have limited treatment options, making access to medicines such as Ibrance critically important,” said Bret Miller, founder of the Male Breast Cancer Coalition. “We applaud the use of real-world data, a new approach to drug review, to make Ibrance available to certain men with metastatic breast cancer and help address an unmet need for these patients.”

Real-world data is playing an increasingly important role in expanding the use of already approved innovative medicines.1 Due to the rarity of breast cancer in males, fewer clinical trials are conducted that include men resulting in fewer approved treatment options. In the U.S. in 2019, it is estimated that there will be 2,670 new cases of invasive breast cancer and about 500 deaths from metastatic breast cancer in males.2 The 21st Century Cures Act, enacted in 2016, was created to help accelerate medical product development, allowing new innovations and advances to become available to patients who need them faster and more efficiently.3 This law places additional focus on the use of real-world data to support regulatory decision-making.4

Detailed analysis of the use of Ibrance in men with HR+, HER2- advanced or metastatic breast cancer will be presented at an upcoming medical meeting. Based on limited data from postmarketing reports and electronic health records, the safety profile for men treated with Ibrance is consistent with the safety profile in women treated with Ibrance.5
