Ovarian Cancer

Niraparib administered as maintenance therapy showed clinical benefit lasting beyond first progression in patients with platinum-sensitive recurrent ovarian cancer with or without germline BRCA mutations, according to the final results of the ENGOT-OV16/NOVA study.

Olaparib maintenance continues to show clinical activity in platinum-sensitive ovarian cancer, including in patients with somatic BRCA mutations and non-BRCA homologous recombination repair mutations.

At the Society of Gynecological Oncology Virtual Annual Meeting on Women’s Cancer data from the phase II OVARIO study continued to show the progression free survival benefit for heavily pretreated patients with advanced ovarian cancer.

CA-125 surveillance alone could be used to detect disease progression in patients with advanced ovarian cancer and an abnormal CA-125 level at the beginning of frontline maintenance therapy with olaparib (Lynparza) and bevacizumab (Avastin), according to an analysis from the phase 3 PAOLA-1 that was presented at the SGO 2021 Annual Meeting on Women’s Cancer.

The addition of the investigational anti–PD-1 immunotherapy agent, dostarlimab, to niraparib and bevacizumab demonstrated positive antitumor activity and tolerability in patients with platinum-resistant ovarian cancer.

Compared with standard-of-care chemotherapy, treatment with the PARP inhibitor rucaparib led to a significant prolongation of progression-free survival and improved duration of response in patients with BRCA-mutated advanced, relapsed ovarian cancer, according to primary results from the phase 3 ARIEL4 trial.

Data from a post hoc analysis of the PRIMA/ENGOT-OV26/GOG-3012 phase III trial showed the efficacy of niraparib maintenance therapy for patients with ovarian cancer who had interval debulking surgery or visible residual disease.

The FDA has accepted a New Drug Application for pafolacianine sodium injection and granted it Priority Review as a potential adjunct for identifying ovarian cancer during surgery.

A novel DNA-mediated interleukin-12 immunotherapy, GEN-1, had been granted a Fast Track designation by the FDA for the treatment of advanced ovarian cancer.

Treatment with rucaparib led to an improvement in investigator-assessed progression-free survival compared with chemotherapy in patients with relapsed ovarian cancer with a BRCA mutation who have received 2 or more prior lines of chemotherapy, meeting the primary end point of the phase 3 ARIEL4 clinical trial.

Patients with newly diagnosed, advanced BRCA-mutated ovarian cancer who experienced complete or partial response following platinum-based chemotherapy continued to exhibit benefit in progression-free survival when receiving olaparib at long-term follow up versus placebo as first-line maintenance.

Binimetinib demonstrated activity as treatment of patients with low-grade serous ovarian carcinomas in the randomized phase 3 MILO/ENGOT-ov11 study.
