The U.S. Food and Drug Administration cleared a test that can help detect ovarian cancer in a pelvic mass that is already known to require surgery. The test, called OVA1, helps patients and health care professionals decide what type of surgery should be done and by whom.
First Lab Test That Can Indicate Ovarian Cancer Prior To Biopsy Or Exploratory Surgery
The U.S. Food and Drug Administration (FDA) cleared the OVA1™ Test [formerly, the Ovarian Tumor Triage Test], the first blood test that, prior to surgery, can help physicians determine if a woman is at risk for a malignant pelvic mass. OVA1 is the first FDA-cleared laboratory test that can indicate the likelihood of ovarian cancer with high sensitivity prior to biopsy or exploratory surgery, even if radiological test results fail to indicate malignancy. The test was developed by Vermillion, Inc. (formerly, Ciphergen Biosystems, Inc. ), a molecular diagnostics company, in cooperation with Quest Diagnostics, the world’s leading provider of cancer diagnostics. Quest Diagnostics, which is a long-time investor in research and development of the OVA1 technology, has exclusive rights to offer the test to the clinical reference laboratory market in the U.S. for three years.
“When combined with other clinical information, the OVA1 biomarker panel can help assess the likelihood of malignancy of an ovarian tumor before surgery and facilitate decisions about referral to a gynecologic oncologist,” said Frederick R. Ueland, M.D., principal investigator of the prospective, multi-center OVA1 clinical trial. Dr. Ueland is an associate professor gynecologic oncology at the University of Kentucky‘s Markey Cancer Center.
The OVA1 Test is an in vitro diagnostic multivariate index [assay] (IVDMIA) test that combines the results of five immunoassays using a proprietary unique algorithm to produce a single numerical score indicating a women’s likelihood of malignancy. The OVA1 Test provides a new option in the pre-operative evaluation to help physicians assess if a pelvic mass is benign or malignant in order to help determine whether to refer a woman to a gynecologic oncologist for surgery. Numerous clinical practice guidelines recommend that women with ovarian cancer be under the care of a gynecologic oncologist. However, only an estimated one third of women who undergo surgery for possible ovarian cancer are referred to these specialist surgeons for their surgery.(1)
Vermillion received the Society for Gynecologic Oncologists (SGO) Basic Science Poster Award for an abstract on the performance of its OVA1 Test presented at SGO’s 38th Annual Meeting on Women’s Cancer in 2007. In reviewing the test application, the FDA evaluated results of a prospective, double-blind clinical trial which included 27 demographically mixed sites representative of institutions where ovarian tumor subjects may undergo a gynecological examination.
“Surgery in the hands of a gynecologic oncologist is usually associated with more favorable patient outcomes,” said Jon R. Cohen, M.D., chief medical officer and senior vice president, Quest Diagnostics. “Physicians often do not know if a woman’s pelvic mass is malignant or benign until she undergoes surgery. The OVA1 Test is the first FDA-cleared blood test to help clinicians determine whether to refer a woman to a gynecologic oncologist or have a gynecologic oncologist present at the time of surgery. We believe this test will help drive more favorable patient outcomes.”
“Unfortunately, advances in ovarian cancer diagnosis and treatment are few and far between. It is fitting that September, Ovarian Cancer Awareness Month, marks FDA’s clearance of OVA1, a test that represents an important step forward toward improved outcomes,” said Gail S. Page, executive chairperson of the board of directors of Vermillion. “Quest Diagnostics had the foresight to recognize the potential value of this novel multivariate assay and supported its development. We look forward to collaborating to bring this new diagnostic option to the many women who will benefit from specialist care.”
The FDA clearance of OVA1 makes Quest Diagnostics the only diagnostic testing company to offer FDA cleared tests for ovarian cancer in the pre- and post-surgical settings. In addition to offering the OVA1 Test, Quest Diagnostics was the first laboratory company to provide a new lab test that the FDA cleared in the third quarter of 2008 as an aid for monitoring for recurrence of epithelial ovarian cancer.
The OVA1 Test will be available for physician use in the fourth quarter of this year.
Ovarian cancer is the leading cause of death from gynecologic cancers in the United States and the fifth-leading cause of cancer deaths in women.(2) Approximately 21,600 new cases of ovarian cancer will be diagnosed in the U.S. in 2009, and approximately 14,600 women will die of the disease.(3)
About the OVA1 Test
The OVA1 Test is a qualitative serum test that combines the results of five immunoassays into a single numerical score. It is indicated for women who meet the following criteria: over age 18, ovarian adnexal mass present for which surgery is planned, and not yet referred to an oncologist. The test utilizes five well-established biomarkers — Transthyretin (TT or prealbumin), Apolipoprotein A-1 (Apo A-1), Beta2-Microglobulin (Beta2M), Transferrin (Tfr) and Cancer Antigen 125 (CA 125 II) — and a proprietary algorithm to determine the likelihood of malignancy in women with pelvic mass for whom surgery is planned.
The OVA1 Test is an aid to further assess the likelihood that malignancy is present when the physician’s independent clinical and radiological evaluation does not indicate malignancy. The test should not be used without an independent clinical/radiological evaluation and is not intended to be a screening test or to determine whether a patient should proceed to surgery. Incorrect use of the OVA1 Test carries the risk of unnecessary testing, surgery, and/or delayed diagnosis.

Select FDA Comments:
The U.S. Food and Drug Administration today cleared a test that can help detect ovarian cancer in a pelvic mass that is already known to require surgery. The test, called OVA1, helps patients and health care professionals decide what type of surgery should be done and by whom.
OVA1 identifies some women who will benefit from referral to a gynecological oncologist for their surgery, despite negative results from other clinical and radiographic tests for ovarian cancer. If other test results suggest cancer, referral to an oncologist is appropriate even with a negative OVA1 result.
OVA1 should be used by primary care physicians or gynecologists as an adjunctive test to complement, not replace, other diagnostic and clinical procedures.
OVA1 uses a blood sample to test for levels of five proteins that change due to ovarian cancer. The test combines the five separate results into a single numerical score between 0 and 10 to indicate the likelihood that the pelvic mass is benign or malignant.
OVA1 is intended only for women, 18 years and older, who are already selected for surgery because of their pelvic mass. It is not intended for ovarian cancer screening or for a definitive diagnosis of ovarian cancer. Interpreting the test result requires knowledge of whether the woman is pre- or post-menopausal.
