PITTSBURGH, Nov. 06, 2023 (GLOBE NEWSWIRE) -- Krystal Biotech, Inc. (the "Company") (NASDAQ:KRYS), a commercial-stage biotechnology company focused on the discovery, development and commercialization of genetic medicines to treat diseases with high unmet medical needs, today reported financial results and key business updates for the third quarter ended September 30, 2023.

"The third quarter was highlighted by strong commercial execution of the VYJUVEK launch, advancement of the oncology program into the clinic and continued momentum in the CF program," said Krish S. Krishnan, Chairman and CEO of Krystal Biotech. "With respect to the VYJUVEK launch, our guiding vision is centered around optimizing the patient experience, and we have and will continue to work tirelessly to ensure that each patient's journey, with respect to starting on VYJUVEK and staying on it, is smooth, timely and hassle free."

VYJUVEK®

(beremagene geperpavec-svdt, or B-VEC)

For the treatment of Dystrophic Epidermolysis Bullosa (DEB)

The Company received 284 Patient Start Forms from 136 unique prescribers as of the end of the third quarter of 2023:
- 20% of the start forms were generated from patients with dominant DEB;
- 33% of the start forms were from patients 10 years of age or younger; and
- Patient compliance on VYJUVEK is currently tracking at 96%.

The Company has received positive coverage determinations from all major commercial national health plans. Optional Medicaid fee-for-service states initiated coverage in July. The Company expects to receive positive coverage from most mandatory states in the fourth quarter of 2023 and the balance in the first quarter of 2024.
In October, the Company filed for a Marketing Authorization for B-VEC with the European Medical Agency and anticipates approval in the EU in the second half of 2024.
Following acceptance of the open label extension study of B-VEC by Japan's Pharmaceuticals and Medical Devices Agency in July 2023, the Company initiated the extension study and dosed 5 patients. Following completion of the open label extension study, the Company intends to file a Japanese New Drug Application for B-VEC for DEB in the first half of 2024. Details of the trial can be found at https://rctportal.niph.go.jp/en under JRCT ID jRCT2053230075.

Respiratory

KB407 for the treatment of Cystic Fibrosis (CF)

Cohort 1 of the Phase 1 (CORAL-1) study has been enrolled and completed. No severe or serious adverse events were observed in patients treated in Cohort 1 of the CORAL-1 study. We are working to initiate Cohort 2 of the CORAL-1 study following safety review by the Data Monitoring Committee. The CORAL-1 study is a multi-center, dose-escalation trial of KB407 in patients with CF, regardless of their underlying genotype. The Company anticipates announcing data from the Phase 1 study in 2024. Details of the Phase 1 study can be found at www.clinicaltrials.gov under NCT identifier NCT05504837.

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

In September, the Company announced that the U.S. Food and Drug Administration (FDA) had cleared the Company's Investigational New Drug (IND) application for KB408 for the treatment of AATD and granted KB408 Orphan Drug Designation. The Company expects to dose the first patient in a Phase 1 clinical trial (SERPINA-1) in the first quarter of 2024.

Oncology

KB707 for the treatment of solid tumors

In October, the first patient was dosed in the Phase 1 (OPAL-1) study to evaluate intratumoral KB707 in patients with locally advanced or metastatic solid tumor malignancies. Details of the study can be found at www.clinicaltrials.gov under NCT identifier NCT05970497.
The Company presented preclinical data in multiple oncology models at the Society for Immunotherapy of Cancer's annual meeting on November 3 and 4, 2023. Combinatorial IL-2 and IL-12 expressed from the Company's platform technology was shown in one presentation, to provide a synergistic effect in a melanoma model, suppressing treated and non-treated tumor outgrowth, enhancing survival, and eliciting a durable memory response sufficient for recurrent tumor control. Similarly, the Company presented that non-invasive inhalation of vector-encoded IL-2 and IL-12 was found to be both safe and effective in treating lung tumors in a metastasis model, resulting in long-term survival after single or repeated cancer cell challenge, suggestive of prolonged adaptive immunity.
The Company is on track to file an amendment to the existing KB707 IND in the fourth quarter of 2023 to allow the Company to evaluate inhaled KB707 in a clinical trial to treat tumors in a patient's lungs. The Company expects to dose the first patient with inhaled KB707 in the first half of 2024.
In October, the United States Patent & Trademark Office issued to the Company U.S. Patent No. 11,779,660 entitled Viral Vectors for Cancer Therapy.

Dermatology

The Company remains on track to commence the Phase 2 cohort of its KB105-02 (JADE-1) trial for the treatment of TGM1-ARCI in 2024 and plans to file an IND application with the FDA and to initiate a clinical trial of KB104 to treat patients with Netherton Syndrome in late 2024.

Aesthetics

KB301 for the treatment of aesthetic indications

In April, Jeune Aesthetics, Inc., 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 study is on-going, and the Company plans to announce results from this study in the first half of 2024. Details of the Phase 1 study can be found at www.clinicaltrials.gov under NCT identifier NCT04540900.

About VYJUVEK

VYJUVEK is a non-invasive, topical, redosable gene therapy designed to deliver two copies of the COL7A1 gene when applied directly to DEB wounds. VYJUVEK was designed to treat DEB at the molecular level by providing the patient's skin cells the template to make normal COL7 protein, thereby addressing the fundamental disease-causing mechanism.

Indication

VYJUVEK is a herpes-simplex virus type 1 (HSV-1) vector-based gene therapy indicated for the treatment of wounds in patients six months of age and older with dystrophic epidermolysis bullosa with mutation(s) in the collagen type VII alpha 1 chain (COL7A1) gene.

IMPORTANT SAFETY INFORMATION

Adverse Reactions

The most common adverse drug reactions (incidence >5%) were itching, chills, redness, rash, cough, and runny nose. These are not all the possible side effects with VYJUVEK. Call your healthcare provider for medical advice about side effects.

Warnings and Precautions

VYJUVEK gel must be applied by a healthcare provider.

After treatment, patients and caregivers should be careful not to touch treated wounds and dressings for 24 hours.

Wash hands and wear protective gloves when changing wound dressings. Disinfect bandages from the first dressing change with a virucidal agent, and dispose of the disinfected bandages in a separate sealed plastic bag in household waste.
