ELUTYX™ Technology

Sustained-Release Drug Therapy

Our proprietary ELUTYX technology is a biocompatible and bioresorbable hydrogel matrix that encapsulates a drug to provide sustained and localized delivery.1-4 The goals of localized drug delivery are to facilitate targeted delivery of a drug and minimize systemic exposure. 2,5

ELUTYX is highly biocompatible and preservative free.1,6 This hydrogel network is a meshwork that entraps the drug particles.1,6 When administered, the hydrogel matrix hydrates with water, then the drug particles begin to dissolve, diffusing the drug outward from the hydrogel into the surrounding local tissues.1,6 Following the completion of drug delivery, the hydrogel biodegrades and is cleared from the body.1,6,7

The company’s novel technology can be formulated to provide sustained-release from days to months depending on the treatment required.3,4,6,7 The versatile hydrogel platform can be used to deliver both small molecules and large proteins at both small and large molecular weights. 1,6-8
