SAN DIEGO, May 19 /PRNewswire-FirstCall/ -- Halozyme Therapeutics, Inc. , a biopharmaceutical company developing and commercializing products targeting the extracellular matrix (“Matrix”), today announced the presentation of new pre-clinical findings on the controlled modification of the Matrix with HTI-501 at the European Society for Dermatological Research (ESDR) and Japanese Society for Investigative Dermatology (JSID).
HTI-501 is a new recombinant human lysosomal proteinase under development at Halozyme that could provide an effective dermatologic treatment by targeting and degrading the fibrous components of the Matrix in a highly controlled fashion. This Matrix targeting new molecular entity is being explored as a potential solution for therapeutic, as well as aesthetic, dermatology indications for which surgery may be impractical, such as cellulite and certain forms of scarring.
HTI-501 works by a process called enzymatic subscision, which involves degradation of fibrous septae (or cords) in a controllable and predictable manner to release skin tissue from the fibrous cords and smooth out the surface contour, which could be especially beneficial in aesthetic dermatology indications. Other proteinases such as collagenases are not generally feasible therapies for aesthetic dermatology, due to their persistent degradation of surrounding tissue that may create safety concerns or require use of sub-potent dosing regimens. As a strictly pH-dependent enzyme, HTI-501 may be capable of exerting its activity in a tightly regulated fashion.
“Due to strict pH dependence for enzyme activity, lysosomal proteinases have been largely neglected as potential therapeutic proteins due to their inability to digest proteins outside the lysosomal compartment in the cell,” said Gilbert Keller, PhD, Halozyme’s Technical Leader in Dermatology. “By bringing this intracellular environment to the extracellular matrix in a temporal fashion, our platform for controlled modulation of the dermal matrix may provide a novel mechanism for tightly controlled pharmacologic subscision of collagenous interstitial matrix. Additional pre-clinical studies are continuing on our lead candidate, HTI-501.”
About Halozyme Therapeutics, Inc.
Halozyme is a biopharmaceutical company developing and commercializing products targeting the extracellular matrix for the drug delivery, oncology and dermatology markets. The company’s portfolio of products and product candidates is based on intellectual property covering the family of human enzymes known as hyaluronidases. The company’s Enhanze(TM) Technology is a novel drug delivery platform designed to increase the absorption and dispersion of biologics. Its key partnerships are with Roche to apply Enhanze Technology to Roche’s biological therapeutic compounds for up to 13 targets and with Baxter to apply Enhanze Technology to Baxter’s biological therapeutic compound, GAMMAGARD LIQUID 10%. In addition, the company has received FDA approval for two products: Cumulase(R), for use in in-vitro fertilization, and HYLENEX, for use as an adjuvant to increase the absorption and dispersion of other injected drugs and fluids. HYLENEX is partnered with Baxter International Inc. The Company also has a number of different enzymes in its portfolio that are targeting significant areas of unmet need.
