GERMANTOWN, Md., Feb. 11, 2019 /PRNewswire/ -- Precigen, Inc., a wholly-owned subsidiary of Intrexon Corporation (NASDAQ: XON) and a biopharmaceutical company specializing in the development of innovative gene and cellular therapies to improve the lives of patients, today announced that the US Food and Drug Administration (FDA) has cleared the Investigational New Drug (IND) application for Precigen's PRGN-3005, a first-in-class investigational therapy using autologous chimeric antigen receptor T (CAR-T) cells to treat advanced-stage platinum-resistant ovarian cancer patients.
PRGN-3005 is the second candidate to clear IND utilizing Precigen's transformative UltraCAR‑T™ platform that reduces manufacturing time to less than two days following non-viral gene transfer. PRGN-3005 UltraCAR-T is a multigenic CAR-T cell treatment utilizing Precigen's clinically-validated Sleeping Beauty system to co-express a chimeric antigen receptor, membrane-bound interleukin‐15 (mbIL15), and a kill switch for better precision and control in targeting advanced ovarian cancer. This is an open-label, first-in-human Phase 1 dose escalation study to evaluate the safety and maximal tolerated dose of PRGN‐3005 UltraCAR-T.
"This patient population has limited treatment options and ovarian cancer remains one of the most challenging with minimal advances in long-term survival for patients with advanced disease," said Mary L. (Nora) Disis, MD, professor of medicine at the University of Washington and lead investigator for the PRGN-3005 study. "Clinical advancements and new research, including the PRGN-3005 UltraCAR-T study, are needed to make progress in fighting this intractable disease."
Precigen's UltraCAR-T platform has the potential to disrupt the CAR-T treatment landscape by increasing patient access through shortening manufacturing time, decreasing manufacturing-related costs, and improving outcomes using advanced approaches for precise tumor targeting and control of the immune system. The platform brings several key advancements:
"We are pleased our PRGN-3005 UltraCAR-T investigational therapy received clearance from the FDA to advance into the clinic. This is an exciting milestone as it represents the first UltraCAR-T to enter the clinic targeting solid tumors," said Helen Sabzevari, PhD, President of Precigen. "This is an important step for patients and our dedicated employees who continue to work with urgency to execute our important mission of creating innovative medicines with meaningful benefit for patients."
About Ovarian Cancer
Worldwide, nearly 300,000 women are diagnosed with ovarian cancer every year1 and around 22,000 are diagnosed in the US2. Five-year survival rates depend on stage and type of ovarian cancer; however, stage IV survival can drop to as low as 20 percent.3.
