The Phase I trial is an open-label, multi-center, first in human, dose escalation study to evaluate safety, tolerability, anti-cancer activity and to establish the maximum tolerated dose of OATD-02. The study is being conducted at three sites in Poland and will enroll a maximum of 40 patients with selected advanced and/or metastatic solid tumors including colorectal cancer, ovarian cancer, pancreatic cancer or renal cell carcinoma.

Marcin Szumowski, Chief Executive Officer of Molecure, said, "We are very excited to start this first in human clinical trial with OATD-02, the second candidate from Molecure’s proprietary pipeline to enter clinical development. This is another important milestone for the company and underpins our commitment to deliver novel medicines that can provide significant benefit to people suffering from advanced and/or metastatic solid tumors. We believe OATD-02 has shown a very promising pre-clinical profile, and we look forward to seeing the initial data from this first in human study in the latter part of 2023."

Dr Samson Fung, Chief Medical Officer added: "OATD-02 is the first and only dual acting arginase inhibitor in development globally to treat solid tumors. This novel drug candidate has been designed to improve treatment outcomes, including in more advanced disease, helping to restore the patient’s antitumor immune response by overcoming the immunosuppressive tumor environment. The important data emerging from this trial will help to guide future clinical development for OATD-02, which we hope will bring treatment benefits to patients with a broad range of tumors."
