Evaluating SKB264 with Pembrolizumab for Advanced Lung Cancer

A Randomized, Open-Label, Multicenter Phase III Clinical Study of SKB264 in Combination With Pembrolizumab Versus Pembrolizumab as First-Line Treatment for PD-L1 Positive Patients With Locally Advanced or Metastatic Non-Small Cell Lung Cancer

Phase 3 Interventional Sichuan Kelun Pharmaceutical Research Institute Co., Ltd. · NCT06448312

This study is testing if adding a new drug called SKB264 to pembrolizumab can help people with advanced lung cancer live better than using pembrolizumab alone.

What this trial studies

This Phase 3 clinical trial aims to assess the efficacy and safety of SKB264 in combination with pembrolizumab compared to pembrolizumab alone in patients with PD-L1-positive locally advanced or metastatic non-small cell lung cancer (NSCLC). The study is randomized and open-label, involving multiple centers to ensure diverse patient representation. Participants will be monitored for treatment response and safety outcomes as they receive the investigational combination therapy or standard treatment.

Who should consider this trial

Good fit: Ideal candidates include adults with confirmed PD-L1-positive locally advanced or metastatic NSCLC who have not received prior systemic therapy.

Not a fit: Patients with active second malignancies or significant cardiovascular issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new effective option for patients with advanced non-small cell lung cancer.

How similar studies have performed: Other studies have shown promising results with similar immunotherapy combinations, indicating potential for success in this approach.
