Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients with advanced solid tumors that have progressed after at least one line of therapy and express the avb8 integrin protein.

Probably not a fit

Patients with solid tumors that do not express the avb8 integrin protein or those with certain severe comorbidities 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 and effectiveness of CRB-601, a monoclonal antibody targeting the avb8 integrin protein, in patients with advanced solid tumors who have not responded to other treatments. The trial consists of three parts, including dose escalation and combination therapies with immunotherapy and immune-priming radiotherapy. Researchers will assess side effects, blood levels of CRB-601, and its impact on cancer progression. The goal is to determine the optimal dosing and treatment combinations for patients with specific tumor types.

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 choices.

How similar studies have gone: While this approach is novel, similar studies targeting specific tumor markers have shown promise in the past.
