Pioneering next-generation tunable hydrogel solutions for precise, sustained drug delivery

AmacaThera’s clinically validated hydrogel drug delivery platform seamlessly integrates two well-established, biocompatible polymers, hyaluronic acid and methylcellulose, into a proprietary formulation. This innovative injectable hydrogel enables precise, localized, and sustained delivery of therapeutics, ensuring long-acting release exactly where it is needed. The platform is broadly compatible with a diverse array of therapeutic agents, including small molecules, biologics, enzymes, and cells. Its tunability allows for the fine adjustment of drug release parameters, such as rate, duration, and timing tailored to the unique requirements of each clinical application.
