What this trial studies
This clinical trial evaluates the safety, tolerability, and efficacy of NDI-219216 in patients with advanced solid tumors, including those with microsatellite instability. Participants will take the medication daily and attend multiple clinic visits for monitoring and assessments. The study aims to determine the drug's side effects, its effects on the body, and its impact on tumor size. It is a first-in-human, open-label study that includes both dose escalation and optimization phases.
Why it matters
Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced solid tumors that are difficult to treat.
How similar studies have gone: Other studies have shown promise with similar approaches targeting advanced solid tumors, but this specific treatment is novel.
