Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with histologically confirmed metastatic solid tumors and an ECOG performance status of 0-1.

Probably not a fit

Patients with significant cardiac disease, unresolved toxicities from prior treatments, or active brain metastases 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 study evaluates the safety, tolerability, and anti-tumor activity of MDX2001 in patients with advanced solid tumors, including biliary tract, breast, cervical, colon, and endometrial cancers. It consists of a Phase 1a dose escalation to determine the recommended Phase 2 dose, followed by a Phase 1b and Phase 2a expansion focusing on a single indication. The study aims to assess the drug's efficacy and further characterize its pharmacokinetics and immunogenicity.

Why it matters

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

How similar studies have gone: Other studies have shown promise with similar approaches, but the specific application of MDX2001 is novel.
