(Reuters) -Arrowhead Pharmaceuticals will get up to $2 billion from Swiss pharma major Novartis for an exclusive worldwide license to the U.S. drugmaker's experimental therapy that targets neuromuscular conditions such as Parkinson's.
Shares of Arrowhead, which has also partnered with Sanofi and GSK, rose about 4% in early trading following the news.
Novartis has been on a deal-making spree in 2025, including buyouts and licensing pacts, as it prepares for looming patent expirations on several blockbuster medicines.
The company has been looking to acquire Avidity Biosciences, a developer of treatments for rare muscle disorders, according to media reports.
Arrowhead will receive $200 million upfront when the deal closes and up to $2 billion in milestone payments and royalties on future sales. Novartis will receive exclusive worldwide rights to the experimental therapy, ARO-SNCA.
The therapy is in preclinical testing and is designed to lower levels of alpha-synuclein, a protein linked to Parkinson's and related disorders.
The companies said they plan to move the program into human trials as soon as possible.
The agreement also covers future projects using Arrowhead's RNA-targeting platform. Financial terms for those were not disclosed.
Novartis will use Arrowhead's platform to develop additional treatments outside the U.S. drugmaker's current pipeline.
