Alexion (ALXN) Reports Positive Data on Ultomiris From gMG Study

Read MoreHide Full Article

Alexion Pharmaceuticals, Inc. announced that the late-stage study evaluating its long-acting C5 complement inhibitor, Ultomiris, in adults with generalized myasthenia gravis (gMG), a rare autoimmune disorder characterized by severe muscle weakness, met its primary endpoint.

The global phase III randomized, double-blind, placebo-controlled, multicenter 26-week study, which enrolled 175 patients across North America, Europe, the Asia-Pacific and Japan, evaluated the safety and efficacy of Ultomiris in adults with gMG who were not previously treated with a complement inhibitor medicine.

Ultomiris showed compelling efficacy as early as week 1 and sustained for 52 weeks. 

The study met its primary endpoint of change from baseline in the Myasthenia Gravis-Activities of Daily Living Profile (MG-ADL) total score at week 26, with high statistical significance.  In addition, the positive treatment effect was maintained through a total of 52 weeks for the subset of patients who have completed 26 weeks in the extension study to date.

Based on the positive data from the study, Alexion plans to make regulatory filings in the United States, the European Union and Japan, in late 2021 or early 2022.

The study results showed that Ultomiris may help a broader range of patients than those studied in the phase III trial of lead drug, Soliris, which is also approved for gMG. It included those with milder symptoms or who are earlier in their treatment journey. The drug can also reduce the patient burden with its less frequent dosing schedule.

A potential label expansion of the drug will boost its sales, which came in at $346.9 million in the first quarter of 2021. The drug is approved for paroxysmal nocturnal hemoglobinuria (PNH) and atypical hemolytic uremic syndrome (aHUS) to inhibit complement-mediated thrombotic microangiopathy (TMA) in adult and pediatric (one month of age and older) patients.

Shares of the company have surged 15.6% against the industry’s decline of 4%.
