PASADENA, Calif.--(BUSINESS WIRE)--Arrowhead Research Corporation (NASDAQ: ARWR), a nanomedicine company with development programs in oncology, obesity, and regenerative medicine, today announced financial results for its fiscal 2011 third quarter ended June 30, 2011. “In recent months our focus has been on advancing the platform technologies of Calando Pharmaceuticals and Ablaris Therapeutics into the clinic. These innovative nanotechnologies have created drug candidates addressing high unmet clinical needs in cancer and obesity,” said Christopher Anzalone, Chief Executive Officer of Arrowhead. “We are pleased to announce that we have completed enrollment for the Calando Phase 1 trial, marking a significant milestone for us. Consistent with our previously reported interim data from the trial, we have a system that is well tolerated in humans, has the ability to shuttle siRNA into target cells to silence disease-related genes, and can potentially be used to create a virtually limitless number of customized RNAi-based therapies. As I have said in the past, we firmly believe that our RONDEL™ delivery system is capable of solving the primary challenge of RNAi today: safe and effective systemic siRNA delivery.
