PITTSBURGH, November 8, 2021 – Krystal Biotech, Inc., (“Krystal”) (NASDAQ: KRYS), the leader in redosable gene therapies for rare diseases, today reported financial results and key operational progress updates for the third quarter ending September 30, 2021.

“We’ve had a productive third quarter and the momentum continues to build with topline data expected from the pivotal GEM-3 trial evaluating B-VEC this quarter,” said Krish Krishnan, Chairman and CEO of Krystal Biotech, Inc. “If positive, this will be a significant milestone for patients living with DEB and strong validation of our redosable gene therapy platform. Outside of the B-VEC program, we are on track to open enrollment in our Phase 1 study of KB407 for cystic fibrosis in Australia and deliver Phase 1 proof-of-concept efficacy data for KB301 from our wholly-owned subsidiary, Jeune Aesthetics in early 2022. As we continue to advance and grow our pipeline, we are also expanding our manufacturing footprint with continued progress on our second facility – ASTRA – which we expect will come online in 2022.”

Program Highlights & Upcoming Events:

B-VEC for DEB

• The Company recently announced completion of the pivotal GEM-3 trial of topical B-VEC for the treatment of DEB, and expects topline data in the fourth quarter of 2021. Details of the pivotal Phase 3 study can be found at www.clinicaltrials.gov under NCT identifier NCT04491604.

• Enrollment of DEB patients into the open label extension (“OLE”) study, including patients who participated in the Phase 3 study as well as new participants who were unable to participate in the Phase 3 study who meet all enrollment criteria, is ongoing.
