New cocktail therapy aims to tackle Drug-Resistant lung cancer

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: The study will enroll adult patients (aged 18-75 years) with histologically confirmed locally advanced or metastatic NSCLC (AJCC 9th Edition, Stage IIIB-IVB), and harbor confirmed actionable driver mutations for which targeted therapies are available; these mutations are stratified as follows: EGFR (19del, L858R); ALK, ROS1, RET fusions; KRAS G12C; BRAF V600; and HER2 exon 20 insertions. Patients must have disease progression following at least one line of TKI therapy and a 2-week washout period is required for prior TKI therapy or chemotherapy. Prior immunotherapy is not permitted. PD-L1 tumor proportion score (TPS) ≥ 50%, as confirmed by central laboratory testing using the 22C3 or SP263 clone on fresh or archival tumor tissue (collected within 2 years). Patients must have an Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1, and presence of at least one measurable lesion per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1. Exclusion Criteria: * Prior treatment with QL1706 or other investigational PD-1/PD-L1/CTLA-4 antibodies, unless allowed by the protocol. * Untreated or symptomatic central nervous system (CNS) metastases. Participants with previously treated, stable, and asymptomatic CNS metastases off steroids for at least 2 weeks before first dose may be eligible. * History of severe allergic reactions or hypersensitivity to monoclonal antibodies, platinum agents, pemetrexed, bevacizumab, or any excipients of the study drugs. * Clinically significant cardiovascular disease, including but not limited to: * Uncontrolled hypertension despite optimal medical management * New York Heart Association (NYHA) class III or IV heart failure * Unstable angina, myocardial infarction, or stroke within 6 months prior to enrollment * Significant arrhythmias requiring anti-arrhythmic therapy * Active or history of autoimmune disease that has required systemic treatment in the past 2 years (e.g., with disease-modifying agents, corticosteroids, or immunosuppressive drugs), except for conditions such as vitiligo, resolved childhood asthma/atopy, or hypothyroidism on stable replacement therapy. * Active infection requiring systemic therapy, including known active hepatitis B, hepatitis C, or human immunodeficiency virus (HIV) infection, unless well controlled according to protocol-defined criteria. * Significant hemoptysis (e.g., ≥ 2.5 mL of bright red blood) within 3 months prior to enrollment or any evidence of high-risk bleeding or coagulation disorder that would contraindicate bevacizumab. * Major surgery within 4 weeks before first dose of study treatment or anticipated need for major surgery during the study. * Pregnant or breastfeeding women. * Any other serious medical condition, uncontrolled intercurrent illness, psychiatric illness, or social circumstance that, in the opinion of the investigator, would compromise the participant's safety, interfere with study evaluations, or preclude informed consent.
