China’s National Medical Products Administration (NMPA) has granted approval for AstraZeneca’s Soliris (eculizumab) to treat refractory generalised myasthenia gravis (gMG) in adult patients.
AstraZeneca’s subsidiary Alexion CEO Marc Dunoyer stated: “Symptoms of gMG, including difficulties seeing, walking, talking, swallowing and breathing, can have a debilitating impact on daily life for patients and their families, representing a critical need for therapeutic advances.
“We remain committed to expanding access to innovative therapies for rare disease patients in China and around the world.”
The regulatory approval was based on comprehensive data obtained from the Phase III REGAIN trial conducted in 125 patients across South America, North America, Europe and Asia.
The 26-week placebo-controlled, randomised, double-blind, multicentre trial was designed to assess Soliris’s efficacy and safety in refractory gMG adult patients.
The findings showed the clinical benefit of Soliris for anti-AChR antibody-positive gMG patients who had previously failed to progress on immunosuppressive treatment and continued to have significant unresolved disease symptoms.
The therapy’s tolerability and safety profile were found to be consistent throughout the primary treatment period, as well as the open-label extension.
