QL1706 is uniquely engineered to provide dual checkpoint inhibition with reduced CTLA-4 exposure, potentially enhancing efficacy while limiting immune-related toxicity. Bevacizumab adds antiangiogenic activity, aiming to improve immune infiltration and drug delivery. This synergistic approach integrates immunotherapy, antiangiogenesis, and cytotoxic agents to overcome resistance and extend survival. All patients receive dual-agent maintenance (QL1706 + bevacizumab) post-induction.
