Pfizer Gains Regular Approval, Expanded Use for Ibrance
FDA has approved a Pfizer supplemental NDA for Ibrance (palbociclib) that converts the previous accelerated approval to a regular approval based on the results from the confirmatory Phase 3 trial PALOMA-2. The approval also broadens the range of anti-hormonal therapy that may be administered with the therapy. IBRANCE now is indicated in combination with an aromatase inhibitor, expanding on its earlier indication in combination with letrozole, as initial endocrine based therapy in postmenopausal women with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative advanced or metastatic breast cancer.
