Precision Therapeutics, Inc. Announces Topline Prospective Clinical Data Demonstrating Significant Improvement in Overall Survival and Progression Free Survival in Recurrent Ovarian Cancer Using Personalized Chemotherapy Diagnostic ChemoFx®

LOS ANGELES--(BUSINESS WIRE)--Precision Therapeutics, Inc., a life science company that develops and markets personalized medicine products for individualizing cancer care, today announced results from a nine-year, multi-center, blinded prospective clinical study which demonstrated statistically significant improvement in overall survival and progression free survival in 262 patients with recurrent ovarian cancer whose tumors were tested with ChemoFx®, a personalized chemotherapy diagnostic. Recurrent ovarian cancer patients in the clinical study who were treated with a chemotherapy drug identified to be responsive by the ChemoFx assay experienced a statistically significant improvement of 50% in overall survival, versus those patients treated by drugs classified as resistant by ChemoFx. The study also showed statistically significant improvement in progression free survival. In the clinical study, ChemoFx was able to identify at least one sensitive chemotherapy drug for more than half of the recurrent ovarian cancer patients studied, approximately doubling the statistics that show only 25 to 30 percent of cancer patients with recurrent ovarian cancer benefit from a chemotherapy treatment chosen empirically.1 These topline results were presented at a medical symposium and in a poster session held during the Society of Gynecologic Oncology (SGO) Annual Meeting on March 9-12, 2013 in Los Angeles, California.
