QL1706 Combined With Chemotherapy and Anlotinib for the Treatment of Recurrent Ovarian Cancer

Ovarian cancer is one of the most common gynecologic malignancies, with considerable histologic heterogeneity; more than 90 % of cases are epithelial ovarian cancers. Because no reliable tools exist for early detection, approximately 70 % of patients are diagnosed at an advanced stage and have poor prognosis, and \>70 % experience relapse within 3 years of initial treatment. The standard first-line strategy combines cytoreductive surgery, platinum-based chemotherapy, and maintenance with PARP inhibitors. Management of recurrent disease remains one of the most challenging problems in clinical oncology. Bevacizumab, a recombinant humanized anti-VEGF monoclonal antibody that blocks endothelial proliferation and neovascularization, is the prototypic angiogenesis inhibitor used in ovarian cancer. However, randomized trials have demonstrated only progression-free survival (PFS) benefit, with no overall survival (OS) advantage. Pre-clinical data suggest that immunotherapy and anti-angiogenic agents can exert synergistic anti-tumor activity, yet clinical efforts combining bevacizumab with immune-checkpoint inhibitors in recurrent ovarian cancer-whether added to platinum-based chemotherapy, used as maintenance, or evaluated in chemotherapy-free regimens-have thus far been unsuccessful (except in clear-cell histology). Anlotinib is a novel oral multi-target tyrosine-kinase inhibitor that blocks VEGFR-2/3, FGFR 1-4, PDGFR-α/β, c-KIT, and RET, thereby potently suppressing angiogenesis.…
