Alexion To Start Pivotal Study On Ultomiris For ALS In Q1

Alexion Pharmaceuticals Inc. (NASDAQ:ALXN) announced plans to start a pivotal phase III study to evaluate its long-acting C5 complement inhibitor, Ultomiris (ravulizumab), in a new indication — amyotrophic lateral sclerosis (ALS). The study will be called CHAMPION-ALS (n~350) and evaluate the efficacy and safety of Ultomiris across a broad ALS patient population. ALS is a neurological disorder characterized by progressive degeneration of nerve cells in the brain and the spinal cord, which control muscles throughout the body.

Alexion submitted an investigational new drug application (IND) for Ultomiris in ALS to the FDA in the fourth quarter of 2019. The company plans to initiate the phase III study in the first quarter of 2020.

The patients in the study will be randomized on a 2:1 basis to receive Ultomiris or placebo every eight weeks after an initial loading dose and may continue to receive their existing standard-of-care treatment for ALS. After 50 weeks, all patients will receive Ultomiris in a two-year, open-label extension phase of the study. The study will be conducted at about 90 sites across North America, Europe and the Asia Pacific.

Alexion’s share price has gained 1% in the past year against the industry ’s decline of 1.8%.
