PITTSBURGH, May 08, 2023 (GLOBE NEWSWIRE) — Krystal Biotech, Inc. (the “Company”) (NASDAQ: KRYS), a biotechnology company focused on developing and commercializing genetic medicines for patients with rare diseases, today reported financial results and key operational progress updates for the first quarter ended March 31, 2023.

“Krystal had a strong start to 2023, marked by significant progress in commercial preparation activities for our anticipated FDA approval of B-VEC later this month, as well as advancements across our pipeline, which lay the groundwork for long-term value creation,” said Krish S. Krishnan, Chairman and CEO of Krystal Biotech.

Dermatology

B-VEC (beremagene geperpavec) for the treatment of Dystrophic Epidermolysis Bullosa (DEB)

• In January, the Company was notified by the U.S. Food & Drug Administration (FDA) that the Prescription Drug User Fee Act (PDUFA) date for the Company’s Biologics License Application for B-VEC for the treatment of patients with DEB, will be May 19, 2023. In April, the Company began labeling discussions with the FDA.
• The Company was informed by the European Medicines Agency in January 2023 to modify the Pediatric Investigation Plan (PIP) waiver request to include patients between birth and 6 months. The Company has modified and submitted the PIP waiver so that the Marketing Authorization Application procedure can officially start in the second half of 2023 with an approval expected in early 2024.
• The Company was informed by the Ministry of Health, Labour and Welfare (MHLW) of Japan that B-VEC was confirmed as safe for importation under the Cartagena Act. With the approval for the importation of B-VEC under the Cartagena Act, we intend to start an open label extension study of B-VEC in Japan in 2023 with an approval in Japan expected in early 2025.
• In April 2023, the Company presented new data on the compassionate use of topical B-VEC to treat a patient with RDEB with recurrent cicatrizing conjunctivitis at the Association for Research in Vision and Ophthalmology (ARVO) 2023 Annual Meeting. The data presented describes the first application of B-VEC to treat ocular complications in a patient with RDEB under a compassionate use program. The patient underwent surgical symblepharon lysis with pannus removal in the right eye. B-VEC was administered to the patient’s right eye at regular intervals following surgery in addition to routine post-surgical management. B-VEC was well tolerated and associated with full corneal healing by 3 months as well as significant visual acuity improvement from hand motion to 20/40 at 7 months, the latest time point of the ongoing treatment effect evaluation.

Rare dermatological pipeline

• The Company plans to initiate the Phase 2 cohort of its KB105-02 (JADE-1) trial in the first half of 2023. The Phase 2 cohort will enroll both pediatric and adult patients with TGM1 deficient autosomal recessive congenital ichthyosis for assessment of KB105 safety and efficacy. Details of the Phase 1/2 study can be found at www.clinicaltrials.gov under NCT identifier NCT04047732.
• The Company is working on an investigational new drug (IND) filing for KB104 for the treatment of Netherton Syndrome. The Company is on track to file an IND for KB104 in 2023.

Respiratory

KB407 for the treatment of Cystic Fibrosis

• In August 2022, we announced that the FDA had accepted our IND application to evaluate KB407 in a clinical trial to treat patients with Cystic Fibrosis. We are closely working with the Therapeutics Development Network of the Cystic Fibrosis Foundation to validate our Phase 1 clinical protocol. We plan to initiate a Phase 1 clinical trial in the U.S. in the first half of 2023. Details of the Phase 1 study can be found at www.clinicaltrials.gov under NCT identifier NCT05504837.
• Screening activities are ongoing for a Phase 1 clinical trial in Australia to study safety and determine frequency of dosing application. Details of the Phase 1 study can be found at www.clinicaltrials.gov under NCT identifier NCT05095246.

KB408 for the treatment of Alpha-1 Antitrypsin Deficiency (AATD)

• The Company is performing preclinical and manufacturing activities and is on track to initiate a Phase 1 clinical trial of KB408 for the treatment of AATD in the second half of 2023.

Aesthetics

KB301 for the treatment of Aesthetic Indications

• In April, Jeune Aesthetics, Inc. (Jeune), a wholly-owned subsidiary of the Company, announced the dosing of the first subject in the Phase 1, Cohort 3 study of KB301 for the improvement of lateral canthal lines at rest. The Phase 1, Cohort 3 study is being conducted at a single center as an openstudy to assess two different doses of KB301 in up to 20 subjects. Improvement of lateral canthal lines at rest was selected as a target indication for KB301 based upon the Phase 1 safety, efficacy and durability studies, which evaluated KB301 in the lower and upper cheek, including the lateral canthal region. Subjects will be followed for three months after KB301 treatment, and the study is expected to be complete in the second half of 2023. Details of the Phase 1 study can be found at www.clinicaltrials.gov under NCT identifier NCT04540900.
