New drug cocktail aims to outsmart resistant lung cancer
NCT ID NCT06745908
First seen Jun 27, 2026 · Last updated Jul 28, 2026 · Updated 2 times
Summary
This phase 3 trial tests whether adding an experimental drug (N-803) to standard chemotherapy (docetaxel) can help people with advanced non-small cell lung cancer whose disease has stopped responding to immunotherapy. About 507 participants will be randomly assigned to receive either the combination or chemotherapy alone. The main goal is to see if the combination helps people live longer.

Have acquired resistance to a regional Health Authority-approved immune plus platinum-based chemotherapy, defined as disease progression immediately following an initial response (of any duration) or stable disease (approximately 6 months duration \[± 2 weeks\]). Participants who received anti-PD-1/anti-PD-L1 mAb as first-line therapy may have received the combination of platinum-based chemotherapy and anti-PD-1/anti-PD-L1 mAb in the second line. Participants must have received platinum chemotherapy to be eligible. Participants must have received anti-PD-1/anti-PD-L1 mAb in their immediate prior line of therapy to be eligible. 5. Participants who receive an immune CPI as consolidation therapy after chemoradiation are eligible if they show progression or recurrence within 3 months of their last CPI and must have received at least 6 months of exactly 1 line of prior CPI therapy. If that CPI is not approved for advanced NSCLC, then an approved alternative CPI will be used. 6. If participants are positive for actionable genomic alteration (AGA), defined as a genomic alteration which has at least 1 regional Health Authority-approved targeted therapy. Participants MUST have received at least 1 targeted therapy or 2 or more if multiple lines of targeted therapies are approved in the region.

Participants must meet inclusion criteria #4. 7. Participants with previously treated brain metastases may participate provided they are clinically stable for at least 2 weeks and have no evidence of new or enlarging brain metastases and also are off steroids 3 days prior to dosing with study medication. Stable brain metastases by this definition should be established prior to the first dose of study medication.
