PASADENA, Calif.--(BUSINESS WIRE)--Insert Therapeutics, Inc., a majority owned subsidiary of Arrowhead Research Corporation (ARWR), announced today that it has filed with the U.S. Food and Drug Administration to initiate a Phase II clinical trial evaluating the safety and efficacy of its drug candidate IT-101 in patients with ovarian cancer. In women who receive a 2nd course of chemotherapy, nearly 75% will achieve some degree of disease stabilization. However, most will experience a recurrence of their cancer within 9 to 12 months after treatment. For these women, the current standard care is to “watch and wait” until disease progression occurs.
