Hyaluron Contract Manufacturing (HCM) Announces Patent Approval

June 24, 2008 — BURLINGTON, Massachusetts June 24, 2008 - Hyaluron, Inc. dba Hyaluron Contract Manufacturing (HCM) is pleased to announce the grant of a patent and the registration of a trademark for its proprietary process for aseptic online vacuum filling and online vacuum stoppering of low viscosity liquids in syringes. BUBBLE-FREE FILLING® enhances product stability for oxygen sensitive compounds where dissolved oxygen negatively impacts solution stability. BUBBLE-FREE FILLING® also provides additional assurances of sterility by reducing stopper movement as well as creating an unfavorable environment for the growth of aerobic micro-organisms.

HCM was able to develop the BUBBLE-FREE FILLING® method by re-engineering standard syringe filling equipment and creating a unique fluid handling and transfer process. HCM has another patent pending for a proprietary aseptic processing method for non-destructive testing of container/closure integrity. HCM is continually striving to improve the safety and effectiveness of drug delivery through its innovative processes.
