Ovarian Cancer

Napabucasin (BBI-608, BB608) is a first-in-class cancer "stemness" inhibitor that targets the STAT3 pathway, has acceptable toxicity, and shows some antitumor activity in combination with paclitaxel in platinum-resistant ovarian cancer. Results of an early phase trial were presented at a poster session at the 2016 ASCO Annual Meeting.

Avelumab (MSB0010718C), a fully human anti-PD-L1 (programmed death-1 receptor ligand) IgG1 antibody, showed activity in patients with heavily pretreated recurrent or refractory ovarian cancer with acceptable toxicity in the phase Ib JAVELIN Solid Tumor trial.

The PARP inhibitor olaparib (Lynparza) significantly increased overall survival (OS) in women with platinum-sensitive relapsed serous ovarian cancer when given as maintenance monotherapy. These interim results, a third updated survival analysis, come from an extension of the Study 19 phase II trial and were presented at the 2016 ASCO Annual Meeting.

Durvalumab, an investigational PD-L1 targeting drug, is the subject of a unique ongoing basket trial being conducted by the National Institutes of Health, and was part of a single arm phase I combination therapy study of the drug in 19 patients with cervical cancer, triple negative breast cancer (TNBC), ovarian cancer, or uterine leiomyosarcoma.

Findings from a population-based study reported at the 2016 ASCO Annual Meeting revealed that young black women with breast cancer are much less likely to undergo testing for the BRCA gene or to get risk reducing prophylactic mastectomy or salpingo-oophorectomy than other women.

Neratinib, an experimental TKI being developed for breast cancer, achieved a 36% clinical benefit rate in a phase II trial, according to a poster presented June 5, 2016 at the ASCO Annual Meeting in Chicago.

Intraperitoneal chemotherapy (IP) was well tolerated by patients with advanced epithelial ovarian cancer (EOC) and reduced the risk of progressive disease.

Sue Naeyaert, senior director of Biosimilars Policy, EMD Serono, discusses the long-term impact that biosimilars could potentially have on the field of oncology.

Intraperitoneal (IP) therapy was not superior to intravenous (IV) treatment when used in combination with bevacizumab (Avastin) as a regimen for patients with advanced ovarian cancer, according to phase III findings from the GOG-252 study.

Tuya Pal, MD, discusses the importance of genetic risk assessment shaping management guidelines in ovarian cancer.

Results from The Cancer Genome Atlas (TCGA) have shown that alterations in gene copy number (ie, amplifications or deletions) are an important characteristic of high-grade serous ovarian cancers (HGSOC).

Yael Cohen, MD, discusses VB111, a highly targeted anti-angiogenic agent. The treatment is currently going through a phase III trial for treating glioblastoma, phase I trial for thyroid cancer and phase II trial for ovarian cancer.

Ovarian cancer outcomes appear to be improved in women with a history of oral contraceptive use, according to a retrospective study recently published in BMC Cancer.

UCLA researchers have discovered a new drug that helps reduce ascites in patients with ovarian cancer through inhibiting certain receptors.

Patients with ovarian cancer who have high-to-medium expression of folate receptor alpha responded well overall to mirvetuximab soravtansine.

Neoadjuvant chemotherapy is increasingly used in advanced ovarian cancer, even though it has not been shown to improve survival versus primary cytoreduction.

Jeffrey R. Infante, MD director of Drug Development, Sarah Cannon Research Institute, talks about the anti-PD-L1 antibody avelumab in patients with previously treated, recurrent or refractory ovarian cancer.

While immune checkpoint inhibitors initially showed promise in patients with ovarian cancer, results still need to be validated by larger randomized trials.

Maurie Markman, MD, president of Medicine and Science, Eastern Regional Medical Center, talks about use of PD-1 inhibitors in ovarian cancer and the lack of evidence pointing toward their functionality.

Researchers note that chronic Hedgehog (Hh) pathway stimulation has been shown in prostate, lung, and ovarian cancers, and that zinc levels decrease early in prostate cancer continuing to castration-resistant disease. Researchers are exploring whether or not zinc may suppress the autocatalysis in the Hh precursor and inhibit production of biologically active Hh ligand.

Noah D. Kauff, MD, FACOG, gynecologist and geneticist, director, Ovarian Cancer Screening and Prevention, Gynecology Service, Department of Surgery, Memorial Sloan Kettering Cancer Center, discusses unanswered questions regarding the treatment of patients with uterine cancer.

Treatment with nivolumab demonstrated clinical efficacy and safety in patients with platinum-resistant, recurrent, or advanced ovarian cancer.

A novel immunotherapy, EGEN-001, combined with pegylated liposomal doxorubicin (PLD) has demonstrated clinical benefit in recurrent or persistent epithelial ovarian, fallopian tube, or primary peritoneal cancer patients.

The fully human PD-L1 IgG1 antibody, avelumab, demonstrated clinical activity in patients who have previously treated, recurrent/refractory (R/R) ovarian cancer.

Results of the CHORUS trial confirm the noninferiority of primary chemotherapy followed by surgery versus primary surgery and then chemotherapy, and show that performing chemotherapy first is associated with less morbidity and mortality in patients with newly diagnosed, advanced ovarian cancer.
