HanAll Biopharma Co., Ltd. (KRX: 009420. KS) announced that its licensed partner Harbour BioMed in Greater China reported positive top-line results from its pivotal Phase 3 clinical trial of batoclimab in generalized myasthenia gravis (gMG) patients. This marks the first positive Phase 3 trial outcome for batoclimab worldwide.


The study met its primary endpoint as well as key secondary endpoints, and batoclimab was found to be well-tolerated with no new safety signals identified. Batoclimab is the first anti-FcRn treatment confirmed efficacious and safe in Chinese gMG population.


This multicenter, randomized, double-blind, placebo-controlled Phase 3 study enrolled 132 adult patients with gMG in China. Patients were randomized to receive batoclimab or placebo as subcutaneous injections by cycle. Each cycle consisted of a treatment period that includes six weekly injections, followed by four weeks of observation period.


“We are thrilled with the outstanding results from the study, which were the first Phase 3 data of our anti-FcRn asset batoclimab. We look forward to continuing our successful partnership with Harbour BioMed and CSPC for patients with gMG in China," said Sean Jeong, M.D., CEO of HanAll Biopharma.


Harbour BioMed and CSPC plan to submit a Biologics License Application to the National Medical Products Administration (NMPA) for batoclimab based on the study results.


Harbour BioMed became HanAll’s licensed partner to develop batoclimab in China in September 2017, and entered into a sub-license agreement with CSPC for batoclimab in October 2022.


Batoclimab is a fully human, subcutaneously administered antibody originated from HanAll, which selectively binds to and inhibits the neonatal Fc receptor (FcRn). It has demonstrated high potential as a new treatment option for gMG patients in China from the Phase 2 study, and received Breakthrough Therapy Designation from the NMPA in 2021.
