AstraZeneca said Tuesday that its Soliris disease treatment has been approved in China for adults with refractory generalized myasthenia gravis, known as gMG.

A rare, chronic, autoimmune neuromuscular disease, gMG leads to a loss of muscle function and severe weakness.

The pharmaceutical major said the drug--also known as eculizumab--has been approved for adults with gMG that are anti-acetylcholine receptor antibody-positive, the third approval in China for the treatment's use for tackling rare diseases.

The National Medical Products Administration's approval was based on comprehensive Phase 3 trial results. In the trial, Soliris demonstrated a clinical benefit in adults that had previously failed immunosuppressive treatment, and continued to suffer from significant unresolved symptoms.

Improvements shown over the initial six-month trial duration were also sustained over a treatment period of more than 130 weeks in a long-term extension trial, the company added.

The treatment's safety and tolerability profile were consistent throughout both the primary treatment period and the extension.
