Evaluating SKB264 with Pembrolizumab for Lung Cancer Treatment

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

Phase 3 Interventional Sichuan Kelun Pharmaceutical Research Institute Co., Ltd. · NCT06711900

This study is testing if a new drug called SKB264, when used with pembrolizumab, works better than standard chemotherapy with pembrolizumab for patients with advanced lung cancer that has a specific marker.

What this trial studies

This Phase 3 clinical trial investigates the efficacy and safety of SKB264 combined with pembrolizumab compared to chemotherapy combined with pembrolizumab as a first-line treatment for patients with locally advanced or metastatic non-squamous non-small cell lung cancer (NSCLC) that is PD-L1 negative. The study is randomized and open-label, involving multiple centers to ensure diverse patient representation. Participants will be monitored for treatment outcomes and safety profiles to determine the effectiveness of SKB264 in this patient population.

Who should consider this trial

Good fit: Ideal candidates are adults with locally advanced or metastatic non-squamous NSCLC who are PD-L1 negative and have not received prior systemic therapy.

Not a fit: Patients with specific genetic mutations that are eligible for targeted therapies or those with other types of lung cancer may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new effective option for patients with PD-L1 negative non-squamous NSCLC.

How similar studies have performed: Other studies have shown promising results with immunotherapy combinations in lung cancer, but this specific combination is being evaluated for the first time.
