US FDA and Emgality

The US Food and Drug Administration (or FDA) has conditionally accepted the brand name of Emgality. The investigational drug is a self-administered once-monthly injection for the prevention of migraines and cluster headaches.

Phase three study

The episodic cluster headache study was a randomized, double-blind, placebo-controlled study evaluating the safety and efficacy of Emgality 300 mg once monthly as compared to the placebo. The study was done on 106 patients over two months, and the average cluster headache attacks were 17.5 attacks per week in the beginning.

The primary endpoint was a change in the average attacks per week across weeks one to three. The secondary endpoint was a response rate where patients achieved at least 50% fewer attacks per week at week three.

The patients treated with Emgality reported a significant reduction in weekly cluster headache attacks as compared to patients who received the placebo. Also, ~76% of total patients receiving Emgality achieved a 50% reduction in weekly cluster headache attacks as compared to 57% of patients receiving the placebo at week three.

Eli Lilly will present detailed results for the study at the American Headache Society’s annual meeting on Saturday, June 30, as a late-breaking presentation.

The Health Care Select Sector SPDR ETF (XLV) holds 2.5% of its total investments in Eli Lilly (LLY), 2.7% in Bristol-Myers Squibb (BMY), 3.8% in Amgen (AMGN), and 1.9% in Biogen (BIIB).
