Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include pediatric and young adult patients diagnosed with specific hematologic malignancies or solid tumors as outlined in the eligibility criteria.
✕Probably not a fit
Patients with a history of solid organ transplant, significant cardiovascular disease, or certain other medical conditions may not benefit from this study.

What this trial studies
This study evaluates the safety and efficacy of zilovertamab vedotin in pediatric and young adult participants with relapsed or refractory hematologic malignancies, such as B-cell acute lymphoblastic leukemia and diffuse large B-cell lymphoma, as well as solid tumors like neuroblastoma and Ewing sarcoma. It is part of a larger platform study aimed at understanding the potential of this treatment in various cancer types. Participants will receive the investigational drug and be monitored for responses and side effects.
Why it matters
Potential benefit: If successful, this treatment could provide a new therapeutic option for young patients with difficult-to-treat cancers.
How similar studies have gone: Other studies have shown promise with similar approaches, but the specific application of zilovertamab vedotin in this population is novel.
