Novartis Kisqali® (Ribociclib, LEE011) Receives FDA Approval as First-Line Treatment for HR+/HER2- Metastatic Breast Cancer in Combination with Any Aromatase Inhibitor

Excerpt:

“The US Food and Drug Administration (FDA) has approved Kisqali®(ribociclib, formerly known as LEE011) in combination with an aromatase inhibitor as initial endocrine-based therapy for treatment of postmenopausal women with hormone receptor positive, human epidermal growth factor receptor-2 negative (HR+/HER2-) advanced or metastatic breast cancer.

“Kisqali is a CDK4/6 inhibitor approved based on a first-line Phase III trial that met its primary endpoint early, demonstrating statistically significant improvement in progression-free survival (PFS) compared to letrozole alone at the first pre-planned interim analysis. Kisqali was reviewed and approved under the FDA Breakthrough Therapy designation and Priority Review programs.”

Entinostat Anchors New Combo in HR+ Breast Cancer Study

Excerpt:

“A dual approach to overcoming resistance to endocrine therapy in patients with advanced hormone receptor (HR)–positive breast cancer is under investigation in a phase III trial that adds the novel drug entinostat to standard exemestane therapy after disease progression.

“The combination has generated excitement in the oncology drug development field after demonstrating an 8-month overall survival (OS) benefit over exemestane alone in the phase II ENCORE 301 study. Those positive results prompted the FDA to grant a breakthrough therapy designation to entinostat in this setting.”

FDA Expands Palbociclib Approval for Breast Cancer

“The Food and Drug Administration (FDA) has granted an expanded indication for the cyclin-dependent kinase 4/6 inhibitor palbociclib (Ibrance). The drug is now approved for use in combination with fulvestrant in women with hormone receptor (HR)-positive, HER2-negative advanced or metastatic breast cancer whose disease progressed following endocrine therapy.

“Palbociclib was initially approved in February 2015 for the treatment of estrogen receptor–positive, HER2-negative metastatic breast cancer, in women who had not yet received endocrine therapy. The new approval was granted under the FDA’s breakthrough therapy designation.

“The additional indication for palbociclib is based on results from the PALOMA-3 trial, which was stopped early in April 2015 after an interim analysis showed benefit in combination with fulvestrant when compared to fulvestrant and placebo.”
