SHANGHAI & SUZHOU, China

EpimAb Biotherapeutics, a clinical-stage biotechnology company specializing in bispecific antibody development, today announced that the U.S. Food and Drug Administration (FDA) has cleared the Investigational New Drug (IND) application for a Phase Ib/II study in patients with non-small cell lung cancer (NSCLC) evaluating the combination of EMB-01, a bispecific antibody designed to simultaneously target EGFR and cMET on tumor cells, and Tagrisso® (osimertinib), AstraZeneca’s (LSE/STO/Nasdaq: AZN) third-generation EGFR-TKI. AstraZeneca is providing Tagrisso® for this trial under a non-exclusive clinical trial collaboration agreement.

“This is an important milestone for EpimAb as we continue on our trajectory to advance our bispecific pipeline and look to explore the potential of our assets for combination therapy,” said Dr. Chengbin Wu, founder and CEO of EpimAb. “EMB-01 has demonstrated efficacy in multiple preclinical models as well as in our ongoing clinical trial program. We look forward to evaluating the potential synergies of this asset with Tagrisso in this study, alongside our ongoing global Phase I/II study of EMB-01 as a monotherapy.”

“Non-small cell lung cancer is one of the most common oncology indications worldwide, yet there remains a huge unmet need among NSCLC patients with EGFR mutations who develop resistance to third-generation TKIs,” said Dr. Bin Peng, CMO of EpimAb. “The combination of EMB-01 and Tagrisso has the potential to synergistically inhibit tumor growth, ultimately expanding treatment options for patients.”

The planned Phase Ib/II trial will evaluate the safety and tolerability of EMB-01 in combination with Tagrisso® in patients with NSCLC with EGFR mutations. Pharmacokinetics, immunogenicity, and the anti-tumor activity of EMB-01 combined with Tagrisso® will also be assessed.
