Arrowhead Pharmaceuticals saw a boost in its stock price after the U.S. Food and Drug Administration (FDA) approved its groundbreaking treatment, REDEMPLO (plozasiran). The approval of this small interfering RNA (siRNA) drug represents a significant milestone for the company and promises to change the lives of patients suffering from familial chylomicronemia syndrome (FCS). The drug, which can be self-administered once every three months, is set to be a game-changer for those with this rare and severe condition.
FDA Approval Marks Major Milestone for Arrowhead
The FDA approval of REDEMPLO establishes Arrowhead Pharmaceuticals as a leader in RNA-based therapies. This approval makes REDEMPLO the first FDA-approved siRNA medicine for FCS, a disease that affects approximately 6,500 people in the U.S. FCS causes dangerously high triglyceride levels, which can lead to recurrent and potentially fatal pancreatitis. The approval is a turning point for Arrowhead, marking the company’s first FDA-approved treatment using its proprietary TRiM™ platform.
The REDEMPLO treatment’s approval was based on the successful results of the Phase 3 PALISADE study, a randomized, double-blind trial involving adults with genetically confirmed or clinically diagnosed FCS. The study demonstrated that the 25 mg dose of REDEMPLO resulted in significant triglyceride reduction, with patients showing an 80% median reduction compared to a 17% reduction in the placebo group. The treatment showed a lower incidence of acute pancreatitis, a key complication of FCS.
Christopher Anzalone, CEO of Arrowhead Pharmaceuticals, expressed pride in this achievement, noting the approval as a testament to the company’s dedication to innovation. The approval also reflects Arrowhead’s commitment to providing life-changing therapies to patients with severe diseases.
REDEMPLO’s Potential to Transform Treatment for FCS
REDEMPLO offers a breakthrough in the treatment of FCS, a rare genetic disorder characterized by high triglyceride levels. The drug’s self-administered subcutaneous injection can be administered every three months, providing patients with a more convenient treatment option. This approval also reinforces Arrowhead’s ability to deliver next-generation therapies leveraging its TRiM™ technology.
In addition to its immediate impact on the FCS community, REDEMPLO holds significant promise for treating a variety of other diseases. Arrowhead’s TRiM™ platform enables the potential for delivering siRNA to seven different cell types and silencing the expression of multiple genes within a single molecule. The success of REDEMPLO may lead to future treatments targeting a broader range of genetic diseases.
With the FDA approval secured, Arrowhead plans to launch REDEMPLO in the U.S. before the end of the year. To ensure patients have access to the treatment, Arrowhead is also introducing a support program called Rely On REDEMPLO. This program will offer financial assistance and support services to help patients navigate their treatment journey.
