Gen-Probe Incorporated (GPRO) Files US Regulatory Application for PROGENSA(R) PCA3 Assay, New Molecular Test to Help Determine Need for Repeat Prostate Biopsies



9/22/2010 8:32:53 AM

SAN DIEGO, Sept. 21 /PRNewswire-FirstCall/ -- Gen-Probe (Nasdaq: GPRO) announced today that the Company has submitted a Premarket Approval Application (PMA) to the US Food and Drug Administration (FDA) for its PROGENSA® PCA3 assay, a new molecular test that may help determine the need for repeat biopsies in men suspected of having prostate cancer.

"Based on the results of our US clinical study, data from numerous peer-reviewed publications, and our European commercial experience, we believe the PROGENSA PCA3 assay can help determine the need for repeat prostate biopsies, thereby improving patient care," said Carl Hull, Gen-Probe's president and chief executive officer. "In addition, this regulatory submission represents the second of four that we expect to complete in the United States this year. Together, these new products will start an important new sales growth cycle for the Company."

Gen-Probe is seeking FDA approval to use the PROGENSA PCA3 assay to test urine samples from men who previously have had a negative prostate biopsy. In support of this objective, the Company conducted a prospective, multicenter clinical study of the assay that enrolled 507 men. The trial began in August of 2009 and concluded in May of 2010. Gen-Probe intends to present the results of the study at a future medical meeting.

The FDA has formally filed Gen-Probe's PMA, and has advised the Company that a meeting of the Medical Devices Advisory Committee's Immunology Panel will be required to support approval of the PMA. No date for this meeting has been set.

About Prostate Cancer and PCA3

According to the American Cancer Society (ACS), prostate cancer is the second most common type of cancer found in American men (behind skin cancer), and the second-leading cause of cancer death in men (after lung cancer). One in six American men will get prostate cancer during his lifetime, and one in 36 will die from it. The ACS estimates that about 218,000 Americans will be newly diagnosed with prostate cancer in 2010, and that approximately 32,000 men will die from the disease.

PCA3 is a gene that is highly over-expressed in more than 90% of prostate cancers, and that can be quantified in urine specimens following a digital rectal examination. Studies have shown that because PCA3 is highly specific for prostate cancer, it predicts the results of repeat biopsies more accurately than traditional prostate-specific antigen (PSA) testing.

Data from approximately 30 peer-reviewed publications suggest that PCA3 testing, when used with other patient information, may help address some of the well-known challenges urologists face when identifying prostate cancer, such as identifying clinically relevant cancers that need to be treated while minimizing unnecessary biopsies.

Gen-Probe's PROGENSA PCA3 assay, which has been CE-marked for sale in the European Union, is the first urine-based molecular diagnostic assay for prostate cancer. The test has not been approved for marketing in the United States. Gen-Probe acquired exclusive worldwide diagnostic rights to the PCA3 gene from DiagnoCure in November of 2003.
