Summary

This trial tests if two drugs plus chemo work better than one drug plus chemo to treat metastatic lung cancer with gene mutations.

Who is the study for?

This trial is for adults with Stage IV non-squamous NSCLC who haven't had systemic therapy for metastatic disease. They must have specific mutations (STK11, KEAP1, or KRAS), good organ function, and no history of certain cancers or immune disorders. Participants need a life expectancy over 12 weeks, be able to use contraception, and not be pregnant or breastfeeding.

What is being tested?

The study compares the effectiveness of two treatments: Durvalumab plus Tremelimumab with chemotherapy versus Pembrolizumab with chemotherapy in patients whose tumors have specific genetic changes. The goal is to see which combination works better for this type of lung cancer.

What are the potential side effects?

Possible side effects include immune-related reactions affecting organs, infusion-related symptoms like fever or chills, fatigue, nausea, blood cell count changes increasing infection risk. Each patient may experience side effects differently.

Trial Design

2Treatment groups

Experimental Treatment

Group I: Arm B: Pembrolizumab + Platinum-based ChemotherapyExperimental Treatment4 Interventions

Participants will receive pembrolizumab regimen q3w for four 21-day cycles in combination with chemotherapy followed by maintenance therapy (pembrolizumab plus pemetrexed maintenance) q3w until disease progression or unacceptable toxicity for up to 24 months or treatment discontinuation.

Group II: Arm A: Durvalumab + Tremelimumab + Platinum-based ChemotherapyExperimental Treatment5 Interventions

Participants will receive durvalumab plus tremelimumab q3w for four 21-day cycles in combination with chemotherapy followed by maintenance therapy (durvalumab plus pemetrexed maintenance) every 4 weeks (q4w) until disease progression or unacceptable toxicity or treatment discontinuation. During the maintenance therapy phase, participants will receive an additional cycle of durvalumab plus tremelimumab (plus pemetrexed, where applicable) at Week 16.
