About

Efficacy and safety of Tislelizumab combined with Bevacizumab and chemotherapy in patients with persistent, recurrent or metastatic cervical cancer.

Full description

The current standard treatment for persistent, metastatic and recurrent cervical cancer is platinum-based combination chemotherapy as its first-line treatment option. However, the current treatment plan still can not meet the clinical needs of cervical cancer treatment, most patients will progress about 6 months after first-line treatment.

At present, there are many clinical research evidence to support the PD-1 antibody for the treatment of recurrent cervical cancer. Immunotherapy can restore the environment of immune support and promote vascular normalization, while anti-angiogenesis can not only normalize tumor vessels, but also block immunosuppressive signals through many ways, so the two mechanisms complement each other. Inhibition of these two pathways will bring better and more lasting clinical benefits to cervical cancer patients.

This study explores the efficacy and safety of tirelizumab combined with bevacizumab and chemotherapy in patients with persistent, recurrent, or metastatic cervical cancer. combining with immune checkpoint inhibitors on the basis of standard treatment regimens has a more potent and durable antitumor ability mechanistically, no significant adverse reactions overlap between immunotherapy and existing standard regimens from a safety perspective, and multiple immune checkpoint combined with antiangiogenic studies confirm safety in cervical cancer.
