Efficacy and Safety of Bevacizumab (Avastin®) Combined to Weekly Paclitaxel Followed by Bevacizumab (Avastin®) Alone in Patients With Relapsed Ovarian Sex-cord Stromal Tumours (ALIENOR)

Summary

Bevacizumab (called also Avastin ®) is a medicine preventing the creation of new blood vessels (a process called "angiogenesis"). This can reduce blood flow of the tumor and then decreasing the contribution of nutriments and oxygen to the cancer cells and prevent the tumor from growing. In various types of cancers, as lung, breast, colorectal and renal cancer, addition of the bevacizumab to chemotherapy allowed to improve the disease outcome. The bevacizumab already benefits from a marketing authorization (MMA) for these various types of cancers. The bevacizumab has also obtained MMA for the treatment of the ovarian cancer in its most frequent histological form (ovarian carcinoma). Clinical trials conducted in this indication demonstrated the importance to pursue the treatment by bevacizumab after the chemotherapy is ended. This anti-angiogenic medicine is thought to be of a potential interest in sex cords- stromal since this tumors are very well vascularized. The ALIENOR study aims to explore the interest and the clinical benefit of associating bevacizumab to the paclitaxel in order to treat patients suffering from recurring sex cords- stromal tumor treated beforehand by platinum chemotherapy

paper The bayesian estimate for the probability that the 6-month progression-free rate distribution was higher with the combination than with paclitaxel alone was 57%, less than the predefined superiority threshold. PMID 33030515 ↗
