BOSTON, March 06, 2024 (GLOBE NEWSWIRE) — PepGen Inc. (Nasdaq: PEPG), 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 fourth quarter and full year ended December 31, 2023, and highlighted recent corporate developments.
“With important data readouts expected from our two lead programs, 2024 has the potential to be a transformational year for PepGen. In the last year, PepGen made meaningful advancements with our Enhanced Delivery Oligonucleotide (EDO) therapeutic candidates, including the initiation and dosing of patients in both our CONNECT1-EDO51 Phase 2 and FREEDOM-DM1 Phase 1 clinical trials,” said James McArthur, Ph.D., President and CEO of PepGen. “Following the recent completion of enrollment of cohort 1 of our CONNECT1-EDO51 trial, we look forward to sharing preliminary safety, exon 51 skipping, and dystrophin production data from the 5 mg/kg dose in mid-2024.”
Dr. McArthur continued, “We continue to see encouraging enrollment in our ongoing FREEDOM-DM1 Phase 1 clinical trial. People with myotonic dystrophy type 1 (DM1) currently have no approved treatment options that target the root cause of the disease. We believe that PGN-EDODM1 has the potential to be disease-modifying and could generate meaningful, double-digit levels of splicing correction and corresponding correction of functional measures. We look forward to reporting preliminary data from at least the 5 mg/kg dose cohort later this year.”
Recent Program Highlights
PGN-EDO51: Duchenne Muscular Dystrophy (DMD)
PGN-EDO51, PepGen’s lead investigational candidate in development for the treatment of DMD, utilizes the Company’s proprietary EDO technology to deliver a therapeutic oligonucleotide that is designed to target the root cause of this devastating disease. PGN-EDO51 is designed to skip exon 51 of the dystrophin transcript, an established therapeutic target for approximately 13% of people with DMD.
- Phase 2 CONNECT1-EDO51 Clinical Trial of PGN-EDO51 underway and 5 mg/kg cohort fully enrolled: In January 2024, PepGen announced that the first patient had been dosed in its Phase 2, open-label multiple ascending dose (MAD) CONNECT1-EDO51 clinical trial, being conducted in Canada, evaluating PGN-EDO51 in 10 male patients at least 8 years of age with DMD amenable to an exon 51-skipping approach. The starting dose will escalate from 5 mg/kg to 10 mg/kg with a potential for further dose escalations. All dose escalations will be determined based on evaluation of safety data from the prior dose cohort(s).
- PepGen is announcing that the 5 mg/kg PGN-EDO51 dose cohort is fully enrolled. PepGen expects to report preliminary data from this cohort in mid-2024, including initial safety, exon 51 skipping, and dystrophin production data.
- Initiation of CONNECT2-EDO51 Clinical Trial of PGN-EDO51: In March 2024, PepGen announced that it had received authorization from the Medicines and Healthcare products Regulatory Agency (MHRA) to initiate its Phase 2, randomized, double-blind, placebo-controlled MAD CONNECT2-EDO51 clinical trial in the United Kingdom evaluating PGN-EDO51 in approximately 20 male patients at least 6 years of age with DMD amenable to an exon 51-skipping approach. PepGen plans to extend this study to the United States and other countries, subject to regulatory authorizations. The CONNECT 2-EDO51 clinical trial, together with the data from CONNECT1-EDO51, is designed to potentially support a future accelerated approval pathway, subject to alignment with regulatory authorities.
PGN-EDODM1: Myotonic Dystrophy 1 (DM1)
PGN-EDODM1, PepGen’s second investigational candidate in development for the treatment of DM1, utilizes the Company’s proprietary EDO technology to deliver a therapeutic oligonucleotide that is designed to restore the normal splicing function of MBNL1. DM1 is a progressively disabling, life-shortening genetic disorder. DM1 is estimated to affect 40,000 people in the U.S., and over 74,000 people in Europe.
- Fast Track Designation granted to PGN-EDODM1: In February 2024, PepGen announced that the U.S. Food and Drug Administration granted Fast Track Designation to PGN-EDODM1 for the treatment of DM1.
- First Patient Dosed in Phase 1 FREEDOM-DM1 Clinical Trial of PGN-EDODM1: In December 2023, PepGen announced that the first patient had been dosed in its Phase 1 single ascending dose (SAD) FREEDOM-DM1 clinical trial evaluating PGN-EDODM1 in 24 adult patients with DM1 in the U.S., Canada, and the United Kingdom. The starting dose of 5 mg/kg can escalate to 10 mg/kg, and then 20 mg/kg based on evaluation of safety data from the prior dose cohort(s).
- PepGen anticipates reporting preliminary data from at least the 5 mg/kg PGN-EDODM1 dose cohort, including safety, splicing correction, and functional outcome measures, in the second half of 2024.
In addition to the ongoing FREEDOM-DM1 trial, PepGen expects to open its FREEDOM2-DM1 placebo controlled, MAD clinical trial in DM1 patients in the second half of 2024.
Preclinical PGN-EDO53: DMD
PGN-EDO53 is PepGen’s third investigational candidate for the treatment of DMD that utilizes the Company’s proprietary EDO technology to deliver a therapeutic oligonucleotide that is designed to target the root cause of this devastating disease. PGN-EDO53 is designed to skip exon 53 of the dystrophin transcript, an established therapeutic target for approximately 8% of people with DMD.
- PepGen plans to advance PGN-EDO53 into investigational new drug (IND) and clinical trial application (CTA) enabling nonclinical studies.
Additional Corporate Highlights
$80 Million Underwritten Offering of Common Stock: In February 2024, PepGen priced an underwritten offering of 7,530,000 shares of common stock at a price to the public of $10.635 per share, for aggregate gross proceeds to PepGen of approximately $80 million, before deducting commissions and expenses payable by PepGen.
Financial Results for the Three Months and Twelve Months ended December 31, 2023
- Cash and cash equivalents were $110.4 million as of December 31, 2023. Based on the Company’s current operating plan and projections, it believes that current cash, cash equivalents and marketable securities, together with the net proceeds from its recent common stock offering, will be sufficient to fund projected operating requirements into 2026.
- Research and development expenses were $16.3 million for the three months ended December 31, 2023, compared to $13.2 million for the same period in 2022. Research and development expenses were $68.1 million for the year ended December 31, 2023, compared to $54.1 million for the same period in 2022. The increase in research and development expenses was primarily due to costs associated with the advancement of the Company’s PGN-EDO51 and PGN-EDODM1 programs, including preclinical, clinical, and manufacturing costs for our ongoing and future clinical trials.
- General and administrative expenses were $4.5 million for the three months ended December 31, 2023, compared to $4.0 million for the same period in 2022. General and administrative expenses were $16.6 million for the year ended December 31, 2023, compared to $14.2 million for the same period in 2022. The increase in general and administrative expenses was primarily due to increased personnel-related costs.
- Net loss was $19.5 million for the three months ended December 31, 2023, compared to $14.9 million for the same period in 2022. Net loss was $78.6 million for the year ended December 31, 2023, compared to $69.1 million for the same period in 2022. PepGen had approximately 23.8 million shares outstanding on December 31, 2023.
