What this trial studies

This Phase 1/2 master protocol study aims to assess the safety, tolerability, and effectiveness of DCC-3009 in patients with gastrointestinal stromal tumors (GIST). The study employs a modular approach, where each module focuses on DCC-3009 alone or in combination with other anticancer therapies. Participants will undergo treatment in 28-day cycles, with the study lasting up to two years. The trial includes dose escalation and expansion phases to determine the optimal dosing regimen.

Who should consider this trial

Good fit: Ideal candidates are adults with advanced or metastatic GIST who have documented KIT or PDGFRA mutations and have progressed on or were intolerant to at least one approved TKI.

Not a fit: Patients with active central nervous system malignancies or those requiring immediate treatment for other cancers may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced GIST who have not responded to existing therapies.

How similar studies have performed: Other studies have shown promise with similar approaches targeting GIST, but the specific use of DCC-3009 is novel.
