Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 to 75 with locally advanced or metastatic NSCLC that is PD-L1 negative and who have not received prior systemic therapy.

Probably not a fit

Patients with EGFR sensitive mutations, ALK gene translocations, or those who have previously been treated with immune checkpoint inhibitors may not benefit from this study.

What this trial studies

This study aims to assess the efficacy and safety of QL1706 in combination with platinum-based chemotherapy compared to tislelizumab with chemotherapy in patients with PD-L1 negative, locally advanced or metastatic non-small cell lung cancer (NSCLC). It is a randomized, double-blind, active-controlled Phase 3 clinical trial involving approximately 608 patients, who will be randomly assigned to either the experimental or control group. Participants will be stratified based on factors such as tumor type and presence of brain metastasis to ensure balanced groups for analysis.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients with PD-L1 negative NSCLC, potentially improving outcomes in this challenging population.

How similar studies have gone: Other studies have explored similar combinations of chemotherapy and immunotherapy, but the specific approach of QL1706 in this context is novel.
