New drug cocktail aims to boost immune attack on lung cancer
NCT ID NCT05565378
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 2 trial tests several new immunotherapy drug combinations in people with advanced non-small cell lung cancer that has high levels of a protein called PD-L1. Participants have not had prior treatment for their advanced cancer. The main goal is to check the safety of these combinations, including side effects. About 351 people will take part.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Pembrolizumab, Dostarlimab, Belrestotug, Nelistotug (immunotherapy drugs)
- What this could lead to
- If successful, this could lead to more effective first-line treatment options for advanced lung cancer with high PD-L1 expression.
- What could go wrong
- This is an early phase 2 trial with a focus on safety, so it is not yet proven to work. The combinations may cause serious side effects or not improve outcomes compared to existing therapies.
