IND filing of second bispecific antibody candidate developed from EpimAb�s FIT-Ig� platform

SHANGHAI--(BUSINESS WIRE)--EpimAb Biotherapeutics, a clinical stage biotech company specializing in bispecific antibodies, today announced that it has received �STUDY MAY PROCEED� letter from the U.S. Food and Drug Administration (FDA) on an Investigational New Drug (IND) application for the Company�s second therapeutic development candidate, EMB-02. The application was submitted to the FDA to investigate the treatment of solid tumors with EpimAb�s novel bispecific antibody.

�The advancement of our second bispecific antibody into the clinic expands our clinical portfolio and also shows that our FIT-Ig� technology can generate a variety of clinical candidates,� commented Dr. Chengbin Wu, founder and CEO of EpimAb Biotherapeutics. �We expect to file additional applications in the near future for novel bispecific antibody programs being developed to treat patients suffering from serious cancer types. In 2021, we expect to have a total of three programs under investigation in clinical trials.�

EMB-02 is a bispecific antibody based on EpimAb�s proprietary FIT-Ig� (Fabs-In-Tandem Immunoglobulin) technology to generate bispecific molecules with superior properties. EMB-02 simultaneously targets two checkpoint proteins, PD-1 and LAG-3, and has shown strong anti-tumor activities in preclinical models resistant to standard anti-PD-1 monotherapies.

While EMB-02 is progressing towards the clinic, EpimAb continues to investigate EMB-01, its lead candidate, in a Phase I/II clinical study in both China and the U.S., and is generating several additional biologics, creating a proprietary pipeline based on its FIT-Ig� platform. These earlier-stage assets are focused on immuno-oncology approaches in areas of high unmet medical need in cancer.
