Invitae and Collaborators to Present New Data at the 2015 American Society of Clinical Oncology Annual Meeting Focusing on the Clinical Utility of Multi-Gene Panel Tests for Hereditary Breast and Ovarian Cancer

-- Study demonstrates that Invitae’s multi-gene test yields clinically actionable findings for substantially more patients than does traditional single-gene testing --

SAN FRANCISCO--(BUSINESS WIRE)-- Invitae Corporation (NYSE:NVTA), a genetic information company, announced that new data will be presented during the 51st American Society of Clinical Oncology (ASCO) Annual Meeting. The presentation, “Clinical Impact of Multi-Gene Panel Testing for Hereditary Breast and Ovarian Cancer Risk Assessment” (Abstract 1513), will be presented as a poster discussion on Monday, June 1 by Leif W. Ellisen, MD, PhD, program director of breast medical oncology at Massachusetts General Hospital and professor of medicine at Harvard Medical School.

The study was conducted as a collaboration between Invitae, Massachusetts General Hospital, the Stanford University Cancer Institute and Beth Israel Deaconess Medical Center. The goal of the study was to evaluate the clinical utility of multi-gene hereditary cancer tests in a representative patient population meeting appropriate criteria for BRCA1/2 testing. More than 1000 BRCA1/2-negative individuals were tested using a 29- or 25-gene panel, and, for those who carried non-BRCA mutations, the patient care implications of these findings were assessed under uniform criteria based on current oncology practice guidelines.

“For patients without BRCA1/2 mutations, management has traditionally been guided by personal and family history alone, even though it is now well known that mutations in other cancer-risk genes are present in some of these patients,” said Dr. Ellisen. “Our study is among the first to systematically investigate the clinical utility of the new generation of hereditary cancer tests. We find that multi-gene panels yield clinically relevant findings with potentially beneficial management implications for substantially more patients than does BRCA1/2 testing alone.”

The investigators found that the majority of non-BRCA positive results would warrant consideration of a change in care for the patient, over and above any actions that would be considered based on family history alone. Moreover the study showed that genetic testing of family members would also be warranted given the management implications that would be considered for relatives found to be positive for non-BRCA genes.
