Two promising molecular targets for drug development in recurrent and metastatic cervical cancer identified in new study

Recurrent cervical cancer may manifest itself in the form of a local recurrence or a metastatic disease. When cancer spreads from part of its origin to other parts of the body it is said to have metastasized.

NRG Oncology GOG-0240 is the phase 3 randomized trial which demonstrated that the incorporation of bevacizumab with chemotherapy resulted in a statistically significant and clinically meaningful survival benefit for women with recurrent and metastatic cervical carcinoma (NCT00803062). GOG-0240 was a proof of concept in anti-angiogenesis therapy and a proof of principle in supportive care and led directly to an indication for bevacizumab in this disease in over 60 countries. Whole genome sequencing and whole exome sequencing of tumor samples obtained in GOG-0240 suggest that ARID1A and PIK3CA could represent potential targets for drug development in the recurrent/metastatic cervical cancer space. These results were presented by lead author Anjali Y. Hari, MD of the University of California, Irvine during the late-breaking oral session of the Society of Gynecologic Oncology’s (SGO) Annual Meeting in March 2023. NRG Oncology designed and led this trial which was conducted in the National Clinical Trials Network with funding from the National Cancer Institute (NCI), part of the National Institutes of Health (NIH).

“Although the adoption of anti-angiogenesis therapy and immunotherapy have fulfilled previously unmet clinical needs in advanced cervical cancer, nearly all patients will ultimately progress, creating new populations in need of novel treatment. This study, by identifying two promising targets, could potentially lead to new treatment options,” stated Dr. Hari.

From April 6, 2009, and Jan 3, 2012, the Phase III NRG-GOG-0240 trial enrolled 452 patients, who provided 112 tumor samples with sufficient DNA and RNA for mutational analysis. In this study, DNA/RNA were co-extracted from FFPE samples after central pathology review at the NRG Biospecimen Bank at Nationwide Children’s Hospital in Columbus, Ohio. DNA/RNA analytes were shipped to the New York Genomic Center and University of North Carolina for whole genome sequencing, whole exome sequencing, RNA sequencing, and microRNA sequencing. Mutational frequencies were compared with those reported in the TCGA and potential molecular targets for biologic therapy were identified. Pattern recognition, mutational clusters, and bioinformatics are ongoing.
