First-Line PARPi Maintenance in Advanced Ovarian Cancer

Preliminary data showed that the combination of sitravatinib and tislelizumab is well tolerated and may promote antitumor activity when administered to patients with platinum-resistant ovarian cancer, according to a press release from BieGene, Ltd, which reported data from a phase Ib study at the 2019 European Society of Oncology Immuno-Oncology Congress in Geneva, Switzerland.<br /> &nbsp;

Timil Patel, MD, discusses how to sequence therapies in a patient with rectal cancer with a single lung nodule.

Emese Zsiros, MD, PhD, FACOG, assistant professor of oncology, Department of Gynecologic Oncology, Center for Immunotherapy, Roswell Park Comprehensive Cancer Center explains the rationale for the a phase II study, which combined pembrolizumab with bevacizumab in patients with recurrent ovarian cancer. Zsiros presented data on the study in early 2019 at the SGO Annual Meeting.

In patients whose solid<strong> </strong>tumors harbor a mutation in <em>KRAS </em>G12C, therapy with MRTX849 has produced promising responses and acceptable toxicity across 3 tumors types, according to data presented at the 2019 American Association for Cancer Research&ndash;National Cancer Institute&ndash;European Organization for Research and Treatment of Cancer International Conference on Molecular Targets and Cancer Therapeutics.

Jonathan Ledermann, MD, professor of oncology, UCL Cancer Institute, University College London, discusses the results of a subanalysis from the phase III ARIEL trial of rucaparib maintenance treatment for patients with recurrent ovarian carcinoma.

Overall survival was not improved with secondary cytoreduction followed by chemotherapy compared with chemotherapy alone in the phase III GOG-0213 trial, which missed its primary endpoint.

Ovarian Cancer

Given the frequency of <em>FGFR2</em>&nbsp;alterations in intrahepatic cholangiocarcinoma, investigators have identified it as a potential prognostic indicator of survival and a rational target of systemic cancer therapies.

The early development of PARP inhibitors in 2003 focused on their use in combination with cytotoxic chemotherapy agents, but this was eventually abandoned because of excess toxicity.

In an interview with Targeted Oncology, Kathleen Moore, MD,&nbsp;discussed the data surrounding mirvetuximab soravtansine in this patient population and the plans to reevaluate the ADC following the results from the FORWARD I/GOG 3011 clinical trial. She also highlighted other areas of investigation for women with platinum-resistant ovarian cancer.

Kathleen Moore, MD, discusses the findings from the phase III FORWARD-1 trial that investigated mirvetuximab soravtansine in women with folate receptor alpha&ndash;positive platinum-resistant ovarian cancer. These findings were presented at the 2019 ESMO Congress.

In an interview with&nbsp;Targeted Oncology, Willemina R. Geurts-Giele, PhD, discussed the accuracy of detecting&nbsp;MET&nbsp;exon 14 skipping mutations in patients with NSCLC with DNA-based NGS panels. These findings were presented at The Association for Molecular Pathology Annual Meeting and Expo.

TT-00420, an investigational spectrum-selective multiple kinase inhibitor received an orphan drug designation from the FDA for the treatment of cholangiocarcinoma, TransThera Biosciences Co. Ltd announced in a press release.

PARP inhibitors are increasingly relevant for frontline maintenance indications and potentially in combination with chemotherapy for treatment-na&iuml;ve ovarian cancer, including for those with <em>BRCA</em>-wildtype disease, Leslie M. Randall, MD, said to the audience at the <em>37th Annual</em> CFS.
