SKB264 plus SKB118 in NSCLC (phase 2)
Official title: A Phase II Clinical Study to Evaluate Sacituzumab Tirumotecan (SKB264) in Combination With SKB118 for the Treatment of Participants With Locally Advanced or Metastatic Non-Small Cell Lung Cancer
Run by Sichuan Kelun-Biotech Biopharmaceutical Co., Ltd. · NCT07697586 · Data updated 2026-11-12
This phase 2 study tests whether the drug combo SKB264 and SKB118 is safe and helpful for people with NSCLC who don’t have certain mutations.

Is this trial a fit for you?
✓Likely a good fit
Adults with locally advanced or metastatic NSCLC lacking EGFR-sensitizing mutations and ALK fusions, with measurable disease and good performance status (ECOG 0-1).
✕Probably not a fit
Patients with CNS metastases, uncontrolled systemic disease, or specific histologies like small cell or neuroendocrine components may have limited or no benefit.

What this trial studies
This open-label, multicenter study in NSCLC uses a dose-escalation and expansion design to evaluate safety, tolerability, and preliminary efficacy of SKB264 in combination with SKB118. Eligible participants have locally advanced or metastatic NSCLC without EGFR mutations or ALK fusions, an evaluable tumor lesion, good performance status, and adequate organ function. The study collects tumor tissue, follows RECIST v1.1 for response assessments, and requires contraception for both sexes during participation. Sites are located in Jilin and Shanghai in China, led by Sichuan Kelun-Biotech Biopharmaceutical and conducted at multiple centers.
Why it matters
Potential benefit: If successful, the combination could offer a new treatment option for NSCLC patients without EGFR or ALK alterations.
How similar studies have gone: There is currently limited public data on this exact SKB264+SKB118 combination, making results exploratory but built on prior targeted-agent combination approaches.
