Arrowhead Pharmaceuticals Initiates Expanded Access Program for Plozasiran and Announces Upcoming Presentation of Clinical Data

Arrowhead Pharmaceuticals, Inc. (NASDAQ: ARWR) today announced that it has initiated an Expanded Access Program (EAP) to make investigational plozasiran available outside of a clinical trial for patients with familial chylomicronemia syndrome (FCS) who meet certain program eligibility criteria. Arrowhead will also present new final Phase 2 clinical data from the double-blind portion of the SHASTA-2 study of plozasiran in a late-breaking oral presentation at the upcoming American College of Cardiology 73^rd Annual Scientific Session & Expo (ACC.24), being held in Atlanta on April 6-8, 2024.

“Arrowhead is committed to supporting patients living with various lipid disorders and the physicians who treat them. To that end, we are pleased that Dr. Daniel Gaudet, Professor of Medicine at Université de Montréal and President and Scientific Director of ECOGENE-21, will present final data in a late-breaking oral presentation at ACC.24 from the SHASTA-2 study of plozasiran in patients with severe hypertriglyceridemia,” said Bruce Given, M.D., interim chief medical scientist at Arrowhead. “Our Phase 3 PALISADE study of plozasiran in patients with FCS is nearing completion and we are further supporting the patient community by initiating an expanded access program for patients and physicians interested in receiving treatment with plozasiran outside of a clinical trial. In addition, Arrowhead medical affairs representatives will be hosting a company booth at ACC.24 with resources for physicians to learn more about the mechanism of cardiometabolic diseases we are studying and our pipeline of RNAi therapeutics that leverage Arrowhead’s proprietary TRiM platform.”

Arrowhead is committed to bringing new investigational medicines to patients with serious diseases as quickly and efficiently as possible. The company’s EAP is a potential pathway for patients with serious or immediately life-threatening diseases or conditions to gain access to an investigational medical product for treatment outside of clinical trials when no comparable or satisfactory alternative therapy options are available.

The plozasiran EAP is for individuals living with FCS. As with any investigational medicine that has not been approved by regulatory authorities, investigational plozasiran may or may not be effective in treating your diagnosis or condition, and there may be risks associated with its use. If you are a patient or caregiver wishing to know more about this plozasiran EAP for FCS, please discuss this EAP and all treatment options with your treating physician. If you are a treating physician and are seeking information about the plozasiran EAP or would like to request access for a patient, please contact [e-mail].
