Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include adults with advanced or metastatic solid tumors that have progressed after at least one line of therapy and express nectin-4.
✕Probably not a fit
Patients with active or uncontrolled CNS metastases or significant comorbidities may not benefit from this study.

What this trial studies
This clinical trial aims to evaluate the safety and effectiveness of CRB-701 in patients with advanced solid tumors that express the protein nectin-4. It consists of three parts: Part A focuses on determining the maximum tolerated dose (MTD) through dose escalation, Part B assesses the recommended Phase 2 dose (RP2D) using a Bayesian design, and Part C evaluates the RP2D in multiple expansion cohorts. Participants will receive intravenous infusions of CRB-701 and undergo various assessments, including blood tests and imaging scans, to monitor treatment effects.
Why it matters
Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced solid tumors expressing nectin-4.
How similar studies have gone: While this approach is novel in targeting nectin-4, similar studies targeting specific tumor markers have shown promise in the past.
