What this trial studies

This multi-center, open-label study aims to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary activity of REC-1245, an oral medication administered once daily, in participants with unresectable, locally advanced, or metastatic solid tumors. Approximately 85 individuals will be enrolled, with 55 in Phase 1 and 10-30 in Phase 2, receiving treatment for up to 2 years. The study focuses on those who have experienced disease progression or have been intolerant to standard therapies.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with unresectable, locally advanced, or metastatic solid tumors or relapsed/refractory lymphomas who have not responded to standard treatments.

Not a fit: Patients who have received treatment with another RBM39 degrader or have significant gastrointestinal issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with difficult-to-treat advanced cancers.

How similar studies have performed: While this approach is novel, similar studies targeting advanced cancers have shown promise, indicating potential for success.
