Alexion Pharmaceuticals Inc. (ALXN) said Friday data from an interim analysis of a study of Soliris indicate improvements during the initial six-month trial duration were sustained over a three year period.

The Phase 3 open-label extension study evaluated the long-term efficacy and safety of Soliris in adult with generalized myasthenia gravis in muscle and nerve.

Additionally, patients who had previously been treated with placebo in the study showed rapid and significant improvement upon starting treatment with Soliris in the open-label extension, the company said.

Shares were down 1.5% to $126.25 Friday morning.
