Wellmarker Bio Co., Ltd (WMBIO), a biopharmaceutical company with fully-integrated capabilities in discovery, development of new anticancer drugs derived from comprehensive biomarker analysis, announced the first subject has been successfully dosed.


This Phase I clinical trial is an open-label, multicenter, multinational study to evaluate the safety, tolerability, pharmacokinetics, and anti-tumor activity of WM-S1-030. The study will be conducted in 2 parts; a dose-escalation phase (Part 1) and a dose-expansion phase (Part 2). Part 1 will evaluate the safety and tolerability of the oral administration of WM-S1-030 as monotherapy in a dose ascending manner. Part 2 will further investigate efficacy, safety, PK, pharmacodynamics, and alternative dosing regimens including combination therapies.


WM-S1-030 has demonstrated significant tumor growth inhibition in colorectal cancer models that are resistant to Erbitux (generic name: cetuximab), an anti-cancer drug commonly used as a targeted therapy in solid cancers including colorectal cancer. It has so far shown outstanding therapeutic efficacy in extensive preclinical studies, including Patient-Derived tumor Cell (PDC) and Patient-Derived tumor Xenograft (PDX) animal models. The drug is expected to demonstrate efficacy in patients with colorectal cancer across both KRAS wild-type and KRAS mutant genotypes.
