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.

Inclusion Criteria: * Confirmed diagnosis of select locally advanced or metastatic solid tumors that have progressed after at least one line of therapy or have no other standard therapy with proven clinical benefit available. * Measurable disease on imaging as assessed by RECIST 1.1 Eastern Cooperative Oncology Group (ECOG) performance status (PS) greater or equal to 2. * Life expectancy of more than 12 weeks. * Adequate hematologic and end-organ function. Exclusion Criteria: * History of solid tumor malignancies other than the disease under study within 3 years of study enrollment * History of and/or current cardiovascular events or conditions * Chronic severe liver disease or liver cirrhosis * Systemic autoimmune disease * Active thrombophlebitis, thromboembolism or hypercoagulability states or uncontrolled bleeding or diabetes. * Interstitial lung disease within 6 months of study enrollment. * Active or persistent infection * Other conditions that in the opinion of the Investigator would compromise the outcomes of the study.
