Summary

The goal of this clinical trial is to evaluate QL1706 plus bevacizumab with or without chemotherapy in patients with PD-L1-negative, locally advanced or metastatic non-squamous non-small cell lung cancer (NSCLC) previously treated with immune checkpoint inhibitors (ICIs). The primary objectives are: To assess the efficacy and safety of QL1706 combined with bevacizumab (± chemotherapy) in this population. Eligible patients with PD-L1-negative, locally advanced or metastatic non-squamous NSCLC who progressed after prior PD-1/PD-L1 inhibitor therapy will be assigned to one of two treatment arms at the investigator's discretion: Arm 1: QL1706 + bevacizumab + chemotherapy (target enrollment: 67 subjects). Single-agent chemotherapy (selected from regimens not previously received) will be administered, with options including nab-paclitaxel, pemetrexed, or docetaxel. Arm 2: QL1706 + bevacizumab (target enrollment: 10 subjects).

Interventions

Type	Name	Description
DRUG	QL1706 plus bevacizumab with or without chemotherapy	QL1706(iparomlimab and Tuvonralimab) was generated by using MabPair, a new technological platform that enables the production of two antibodies close to their natural forms from a single host cell line and is manufactured as one product. QL1706 contains a mixture of anti-PD-1 IgG4 and anti-CTLA-4 IgG1 that were produced together in a fixed ratio. Each antibody was individually optimized to achieve desirable target coverage and antibody effector functions. Bevacizumab is a monoclonal antibody medication used to treat various cancers and a specific eye disease. It works by blocking a protein called VEGF, which helps tumors form new blood vessels, thus starving the tumor of nutrients and oxygen. Chemotherapy (nab-paclitaxel, pemetrexed, or docetaxel) Nab-paclitaxel, also known as nanoparticle albumin-bound paclitaxel, is a chemotherapy drug used to treat certain cancers. It's a form of paclitaxel that's bound to albumin nanoparticles, which improves its solubility and delivery to cance
