Evaluating OATD-02 for advanced solid tumors

Official title: An Open-label, Multicentre, Dose-escalation, First-in-human Phase I Study to Evaluate Safety, Tolerability and Antineoplastic Activity of OATD-02 in Patients With Selected Advanced and/or Metastatic Solid Tumours (Colorectal Cancer, Ovarian Cancer, Pancreatic Cancer or Renal Cell Carcinoma)

Run by Molecure S.A. · NCT05759923 · Data updated 2026-11-12

This study is testing a new oral medication called OATD-02 to see if it can help people with advanced solid tumors, like colorectal and ovarian cancer, by making their tumors respond better to treatment.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with advanced or metastatic colorectal, renal, pancreatic, or platinum-resistant ovarian cancers that have progressed after standard therapies.

Probably not a fit

Patients with clinically active central nervous system metastases or those unable to take oral medications may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to assess the safety, tolerability, and potential anti-tumor activity of OATD-02, an oral medication, in patients with advanced or metastatic solid tumors, including colorectal, ovarian, renal, and pancreatic cancers. The study employs a Modified Bayesian Optimal Interval (BOIN) design to determine the appropriate dosing based on toxicity levels. A total of 30 patients will be enrolled, with a treatment duration of up to 6 months, to evaluate how OATD-02 may enhance tumor responses to immunotherapy by increasing arginine levels or exhibiting intrinsic anti-tumor effects.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced solid tumors who have limited treatment alternatives.

How similar studies have gone: While this approach is novel, similar studies targeting advanced solid tumors have shown promise in enhancing treatment responses.
