View

Arrowhead Pharmaceuticals develops medicines using RNA interference (RNAi) to silence disease-causing genes. The company’s approach uses a library of RNA chemistries and delivery methods to trigger RNAi, enabling rapid and durable reduction of target gene expression in cells. This gene-silencing strategy aims to treat severe genetic diseases such as cystic fibrosis and hepatitis B by lowering disease-related proteins. Arrowhead’s products are advanced through discovery and development partnerships, licensing deals, and potential commercialization of approved therapies. The company differentiates itself through a broad RNAi platform, proprietary delivery tech, and collaborations with larger pharma firms to advance its pipeline. Its goal is to provide new treatment options for conditions with limited or no effective therapies by translating gene silencing into medicines that can halt or reverse disease progression.

Arrowhead swings to $30.8M profit on $264M revenue as FDA approves first drug REDEMPLO

Arrowhead Pharmaceuticals has raised $264 million in revenue for FQ1 2026, transitioning to a commercial-stage company following FDA approval of REDEMPLO (plozasiran), its first medicine for treating familial chylomicronemia syndrome. The drug also received regulatory clearance in China and Canada, with over 100 initial prescriptions in the US. The company swung to a net income of $30.8 million, compared to a $173.1 million loss in the prior year period. Revenue was boosted by a $200 million upfront payment from a collaboration with Novartis and a $200 million milestone from Sarepta Therapeutics. Arrowhead also initiated a Phase 1/2a trial for ARO-DIMER-PA, the industry's first dual-function clinical candidate targeting two genes in one molecule.

Vanscoy Rare Pharmacy Selected as Exclusive Specialty Pharmacy Provider for Redemplo

Vanscoy Rare Pharmacy selected as exclusive specialty pharmacy provider for Redemplo. Vanscoy Rare Pharmacy, a leading specialty pharmacy focused on supporting people living with rare conditions, announced that it has been selected as the exclusive specialty pharmacy provider for Arrowhead Pharmaceuticals' Redemplo (plozasiran), a small interfering RNA (siRNA) medicine, indicated as an adjunct to diet to reduce triglycerides in adults with familial chylomicronemia syndrome (FCS). FCS is a severe, rare disease, with an estimated 6,500 people in the U.S. living with genetic or clinical FCS, characterized by triglyceride levels that can be 10 to 100 times higher than normal leading to a substantially higher risk of developing acute, recurrent, and potentially fatal pancreatitis. With the FDA approval of Redemplo, patients will have access to a targeted treatment option designed to address the underlying cause of FCS. Through this agreement, Vanscoy Rare Pharmacy will provide patients with comprehensive support at each stage of their treatment journey with Redemplo. Arrowhead launched REDEMPLO independently in the U.S. with the OneREDEMPLO pricing model that creates one consistent price across current and potential future indications. Arrowhead is targeting approximately 5,000 healthcare professionals through personal promotion, complemented by a much broader omnichannel effort. REDEMPLO was recently approved by Health Canada's approval of REDEMPLO as a new treatment option for Canadians living with genetic or clinical FCS, giving patients, providers, and caregivers alike a convenient dosing option that can be self-administered at home with a subcutaneous injection once every three months. Pending regulatory review and approval, Arrowhead expects to potentially launch REDEMPLO later this year in select EU countries and in the UK. In Greater China, REDEMPLO will be marketed by Sanofi. #Redemplo #ArrowheadPharmaceuticals #FCS #VanscoyRarePharmacy #OneRedemplo #exclsuivespecialtypharmacy

Bernstein raises Arrowhead Pharma stock price target to $35 on obesity data

Bernstein raises Arrowhead pharma stock price target to $35 on obesity data. Investing.com - Bernstein SocGen Group has raised the price target on Arrowhead Pharmaceuticals (NASDAQ:ARWR) to $35.00 from $17.00 while maintaining a Market Perform rating ahead of the company's upcoming obesity data update. The new target sits at the low end of analyst projections, which range from $35 to $100, according to InvestingPro data. Currently trading at $66.39, ARWR appears overvalued based on InvestingPro's Fair Value assessment. The price target adjustment reflects increases to Bernstein's severe hypertriglyceridemia (SHTG) estimates and the addition of obesity treatment potential to their valuation model. The new target represents the average of a discounted cash flow analysis to 2035 and an enterprise value to revenue multiple of 1.75x 2035 revenue. This valuation approach aligns with ARWR's current high multiples, with InvestingPro data showing an EV/EBITDA of 72.58 and a Price/Book ratio of 19.36. Bernstein noted that Arrowhead is among several companies pursuing non-incretin mechanisms to treat obesity, with the aim of reducing fat while preserving muscle. Other companies in this space include Eli Lilly, Roche, Regeneron, Scholar Rock, Wave Life Sciences, Alnylam, and Biohaven. Despite not being profitable over the last twelve months, ARWR maintains a strong financial health score of "GREAT" according to InvestingPro's comprehensive analysis, with liquid assets exceeding short-term obligations. The analyst highlighted recent data from Wave Life Sciences suggesting that INHBE, which Arrowhead is also pursuing, may be a better target than myostatin. This disclosure on December 8 generated substantial investor excitement, with Wave shares rising 150% and Arrowhead gaining 12%. Despite the price target increase, Bernstein recommends staying on the sidelines for Arrowhead's upcoming data update, suggesting approximately 20% potential movement in either direction. The firm believes shares are already pricing in substantial optimism, estimating $10-15 of obesity treatment value in the current stock price. In other recent news, Arrowhead Pharmaceuticals has launched Redemplo for Familial Chylomicronemia Syndrome, with Piper Sandler forecasting significant U.S. sales by 2026. The firm raised its price target for Arrowhead to $100, noting Redemplo's superior attributes compared to other treatments. RBC Capital also increased its price target for Arrowhead to $80, citing positive developments and early commercial traction for Redemplo, as well as optimism about upcoming trial results for the company's severe hypertriglyceridemia candidate. H.C. Wainwright set its price target at $85, praising the recently approved Redemplo label for its safety and convenience. Additionally, the U.S. Food and Drug Administration granted Breakthrough Therapy designation to Arrowhead's investigational drug plozasiran for severe hypertriglyceridemia. Arrowhead has also dosed the first subjects in a Phase 1/2a clinical trial for ARO-MAPT, targeting tauopathies such as Alzheimer's disease. This trial utilizes a new delivery system designed to cross the blood-brain barrier, showing potential in preclinical studies.
