What this trial studies

This open-label, multicenter Phase 1/2 trial tests YL242 as monotherapy and in combination with pembrolizumab and chemotherapy across multiple cohorts of adults with advanced solid tumors. Phase 1 will use dose-escalation to define safety, tolerability, and recommended doses, followed by expansion cohorts in Phase 2 that enroll tumor-specific groups such as non-squamous NSCLC, colorectal, and gastric cancers. Eligible participants generally must be adults with ECOG 0–1 and adequate organ function, with most cohorts requiring prior systemic therapy while some cohorts enroll treatment‑naïve patients. Primary endpoints focus on safety and tolerability, with secondary endpoints capturing preliminary anti-tumor activity and pharmacokinetics.

Who should consider this trial

Good fit: Adults (≥18) with advanced or metastatic solid tumors, ECOG performance status 0–1, and adequate organ and bone marrow function, with cohort-specific requirements for prior therapy as noted in the protocol.

Not a fit: Patients intolerant to prior topoisomerase I inhibitors or ADCs carrying topoisomerase I payloads, or those with uncontrolled cardiovascular/cerebrovascular disease, significant pulmonary disease, or leptomeningeal carcinomatosis, are unlikely to be eligible or to benefit.

Why it matters

Potential benefit: If successful, YL242 could offer a new targeted treatment option that helps control tumors in patients with advanced disease who have limited options.

How similar studies have performed: Antibody–drug conjugates and VEGF-targeting approaches have shown clinical activity in several cancers, but YL242 is a novel agent with limited prior clinical data.

Part 5: mCRC, have received at least one (5a) or one (5b) prior line of systemic anti-tumor therapy

Part 6: advanced or metastatic HER2-negative G/GEJ; have received at least one (6a) or one (6b) prior line of systemic anti-tumor therapy

Exclusion Criteria:
