PepGen Reports First Quarter 2022 Financial Results and Recent Corporate Developments

BOSTON, June 16, 2022 (GLOBE NEWSWIRE) — PepGen Inc. (“PepGen”), a clinical-stage biotechnology company advancing the next generation of oligonucleotide therapies with the goal of transforming the treatment of severe neuromuscular and neurological diseases, today reported financial results for the first quarter ended March 31, 2022.

“This has been a year of tremendous growth for PepGen, culminating in our recent transition to a clinical stage company and execution of a successful initial public offering,” stated James McArthur, Ph.D., President and CEO of PepGen. “We are continuing to drive our programs forward, and in April of this year we entered the clinic with PGN-EDO51, our lead program for the treatment of individuals with Duchenne muscular dystrophy (DMD) who are amenable to an exon 51 skipping approach. We look forward to reporting safety, pharmacokinetic and exon skipping data from our Phase 1 healthy normal volunteer study of PGN-EDO51 by the end of 2022 – this will be an important milestone in our efforts to advance this therapy for patients in desperate need of more effective treatment options.”

Recent Corporate Highlights

• In May, PepGen completed an initial public offering, raising $122.9 million in gross proceeds before deducting underwriting discounts and offering expenses.
• In April, PepGen dosed the first healthy normal volunteer (HNV) adult male in a Phase 1 clinical trial of PGN-EDO51 for the treatment of individuals with Duchenne muscular dystrophy (DMD) who are amenable to an exon 51 skipping approach.
• In March, PepGen received clearance from Health Canada of its Clinical Trial Application to initiate the Company’s first-in-human trial of PGN-EDO51.
• PepGen has made several key appointments during recent months, including Laurie Keating as Chair of the Board of Directors; Michelle Mellion, M.D., as Senior Vice President, Head of Clinical Development; Jennifer Cormier as Senior Vice President, Clinical Operations; and Jeffrey Foy, Ph.D. as Vice President, Toxicology.

Anticipated Upcoming Milestones

• PGN-EDO51: PepGen anticipates presenting safety and tolerability, pharmacokinetic and exon 51 skipping data from a Phase 1 HNV trial of PGN-EDO51 for the treatment of DMD by the end of 2022.
• PGN-EDODM1: PepGen anticipates submitting an IND application for PGN-EDODM1 to the U.S. Food and Drug Administration (FDA) in the first half of 2023 to initiate a Phase 1/2 clinical trial in myotonic dystrophy type 1 (DM1) patients.
• Additional Pipeline Assets: PepGen expects to report non-human primate (NHP) exon skipping data for PGN-EDO53, the company’s second DMD program for the treatment of exon 53 skipping amenable patients, in the second half of 2022. Additionally, the Company plans to nominate candidates for PGN-EDO45 and PGN-EDO44, which target the exon 45 and exon 44 DMD patient populations respectively, in the second half of 2022.

Financial Results for the Three Months Ended March 31, 2022

• Cash and cash equivalents were $118.9 million as of March 31, 2022, which excludes the proceeds from our IPO in May 2022. The Company expects that current cash and cash equivalents, including net proceeds from the initial public offering, to be sufficient to fund currently planned operating expenses into the first half of 2025.
• Research and Development expenses were $10.7 million for the three months ended March 31, 2022, compared to $5.5 million for the same period in 2021. The increase in research and development expenses was primarily due to preclinical and manufacturing costs in the lead-up to the Company’s initiation of its Phase 1 HNV trial of EDO51, and preclinical activities for the Company’s earlier-stage assets.
• General and Administrative expenses were $3.2 million for the three months ended March 31, 2022, compared to $1.1 million for the same period in 2021. The increase in general and administrative expenses was primarily due to personnel, legal, and finance-related costs to support public company operations.
• Net loss was $18.2 million, or $18.94 per share, for the three months ended March 31, 2022.
