Is this trial a fit for you?
✓Likely a good fit
Adults (18+) with histologically confirmed locally advanced or metastatic solid tumors harboring KRAS alterations and good performance status (ECOG 0-1).
✕Probably not a fit
Patients without KRAS alterations, those with significant organ dysfunction, or those who do not meet the eligibility criteria may not benefit.

What this trial studies
This is a multicenter, open-label Phase 1 trial starting with dose escalation of an oral ABSK211 to determine safety, tolerability, and pharmacokinetics in participants with KRAS-altered advanced solid tumors. After identifying recommended doses, the study expands to evaluate safety and preliminary efficacy in selected tumor types harboring KRAS alterations. The trial will monitor adverse events, drug exposure, and dosing to optimize the regimen. Enrollment is limited to adults with adequate organ function and a performance status of 0 or 1. Exclusions include allergy to the drug, prior KRAS-targeted inhibitors, and other active malignancies requiring treatment.
Why it matters
Potential benefit: If successful, ABSK211 could become a new treatment option for KRAS-altered solid tumors.
How similar studies have gone: KRAS-targeted approaches have shown variable success; this first-in-human study is a novel evaluation of ABSK211.
