Merck's (MRK) Keytruda Gets FDA Nod for Severe Breast Cancer

Read MoreHide Full Article

Merck & Co., Inc. (MRK - Free Report) announced that the FDA has approved its anti-PD-1 therapy Keytruda (pembrolizumab) for a breast cancer indication. Keytruda in combination with chemotherapy is now approved for treating patients with locally recurrent unresectable or metastatic triple-negative breast cancer (TNBC) whose tumors express PD-L1.

This nod from the regulatory body marks Keytruda’s first approval in the breast cancer setting. Per the company, TNBC is an aggressive and difficult-to-treat cancer, which affects around 15-20% breast cancer patients.

The accelerated approval was based on progression-free survival (PFS) data from the phase III KEYNOTE-355 study, which evaluated Keytruda in combination with three different chemotherapy regimens, namely paclitaxel, nab-paclitaxel or Eli Lilly’s (LLY - Free Report) Gemzar (gemcitabine) and carboplatin in the given patient population.

Data from the study showed that the Keytruda combo significantly reduced the risk of disease progression or death by 35% versus the same chemotherapy regimens alone in TNBC patients whose tumors express PD-L1. The combo regimen significantly improved PFS in the given patient population.

Notably, the continued approval for the TNBC indication may be contingent upon verification and description of clinical benefit in the confirmatory studies.

Shares of Merck have declined 10.8% so far this year against the industry’s increase of 1.1%.

The Hottest Tech Mega-Trend of All

Last year, it generated $24 billion in global revenues. By 2020, it's predicted to blast through the roof to $77.6 billion. Famed investor Mark Cuban says it will produce "the world's first trillionaires," but that should still leave plenty of money for regular investors who make the right trades early.
