Arsia Therapeutics

Arsia Therapeutics was an early-stage biotechnology firm founded in 2013 by MIT professors Dr. Robert Langer and Dr. Alexander Klibanov, in conjunction with Polaris Partners. The company was established to address a significant challenge in the delivery of biologic drugs. Dr. Langer, an Institute Professor at MIT, is a renowned chemical engineer and inventor, considered a pioneer in controlled drug release systems and tissue engineering, with involvement in founding over twenty companies. Dr. Klibanov is also a distinguished professor at MIT. Their collective expertise in biochemical engineering and drug delivery formed the scientific foundation of the company. Alan Crane, a partner at Polaris Partners with a deep history of building successful healthcare companies, also played a significant founding role. The company operated in the rapidly expanding biologics and biosimilars sector of the pharmaceutical market, catering to major pharmaceutical and biotechnology companies.

The core of Arsia's business was its proprietary formulation technology platform designed to reduce the viscosity of highly concentrated protein therapeutics. Many biologic drugs, such as monoclonal antibodies, are highly viscous at the concentrations needed for therapeutic effect, often requiring patients to receive them via slow, inconvenient, and costly intravenous (IV) infusions in a hospital setting. Arsia's technology aimed to solve this by creating low-viscosity, high-concentration drug products. The primary benefit was enabling these biologics to be administered through a simple subcutaneous injection, potentially via an autoinjector pen or patch pump. This method of delivery is more patient-friendly, less invasive, and can be done outside of a clinical setting.

Arsia's business model focused on establishing partnerships with pharmaceutical companies to apply its technology to their drug pipelines. This involved creating subcutaneous versions of existing IV products, developing high-concentration formulations for new clinical candidates, and improving biosimilar molecules. By creating superior versions of existing biologics, known as "biobetters," Arsia's partners could achieve product differentiation, potentially leading to better pricing power and market share. In November 2016, Arsia Therapeutics reached a major milestone when it was acquired by Eagle Pharmaceuticals (NASDAQ: EGRX). The deal was valued at approximately $30 million upfront in cash and stock, with potential for an additional $48 million in milestone payments. The acquisition marked Eagle's strategic entry into the biologics market, leveraging Arsia's platform to enhance its own formulation capabilities.
