Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include adults with unresectable or metastatic solid tumors that have confirmed KRAS mutations and have progressed on or are intolerant to prior therapies.
✕Probably not a fit
Patients who have previously received treatment with a KRAS inhibitor or have conditions that prevent them from taking oral medications may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study evaluates the safety and tolerability of ALTA3263, an oral KRAS isoform-selective inhibitor, in adults with advanced solid tumors that have KRAS mutations. It is an open-label, multicenter Phase 1/1b study designed to assess the pharmacokinetics and preliminary clinical activity of the drug. The study consists of two parts: a dose escalation phase to determine the optimal dose and a dose expansion phase to further evaluate its effects. Participants will be closely monitored for safety and treatment response.
Why it matters
Potential benefit: If successful, this treatment could provide a new targeted therapy option for patients with advanced solid tumors harboring KRAS mutations.
How similar studies have gone: Other studies targeting KRAS mutations have shown promise, indicating that this approach may be effective, though this specific study is exploring a novel agent.
