PITTSBURGH--(BUSINESS WIRE)--Krystal Biotech, Inc. (Nasdaq:KRYS) today announced the presentation of positive preclinical data supporting the ongoing development of KB301, an innovative, investigational therapy designed to reverse the decline of collagen in aging skin. The data will be presented at the American Society for Dermatologic Surgery (ASDS) 2020 Virtual Meeting to be held October 9-11, 2020.

The preclinical program evaluated KB301s ability to transduce clinically relevant skin cells, to express and secrete mature human COL3 in vitro, as well as to confirm proper tissue localization of the transgene without toxicity or systemic vector distribution in vivo.

Key findings from the poster presentation titled In Vitro and In Vivo Pharmacology of KB301, an HSV-1-Based Gene Therapy, for the Treatment of Superficial Skin Depressions include:

The above data presentation will be available on the Scientific Publications page of the Companys website at http://ir.krystalbio.com/select-scientific-publications.

About collagen type III and KB301

The skin is composed of collagen-rich connective tissue composed primarily of types I and III collagen fibrils. Age-related changes in skin are largely due to aberrant collagen homeostasis, caused both by intrinsic (e.g., passage of time, genetics) and extrinsic (e.g., chronic light exposure, pollution) factors, which leads to progressive loss of dermal collagen. KB301 is an investigational therapy designed to restore collagen homeostasis locally via directed expression of full-length human type III collagen gene (COL3A1), thereby reconstructing an optimal physiologic environment in the skin to treat wrinkles and other superficial skin defects. KB301 is manufactured in-house at Krystals fully functional GMP ANCORIS facility, located near corporate headquarters in Pittsburgh. If ultimately successful, KB301 and any additional aesthetic programs will be developed through our wholly-owned subsidiary Jeune, Inc.

About the PEARL-1 Trial

The Phase 1 trial will evaluate the safety, tolerability, and initial efficacy of KB301 injections. Approximately 22 patients will be enrolled across 3 cohorts. The initial, open-label cohort will evaluate the safety and tolerability of 2 different dose levels of KB301 in healthy buttock skin. Following dose selection enrollment will begin in Cohorts 2 and 3, which are double-blind, placebo-controlled, intra-subject evaluations of the safety and efficacy of KB301 in either shallow-to-moderately deep facial wrinkles or moderate-to-severe atrophic acne scars.
