BOSTON--(BUSINESS WIRE)--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 and recent corporate highlights for the quarter ended June 30, 2024.
"Our July readout of the CONNECT1 5 mg/kg clinical data in Duchenne muscular dystrophy (DMD) was the culmination of years of dedicated effort from our team," said James McArthur, Ph.D., President and CEO of PepGen. "In three months, PGN-EDO51 produced higher mean levels of exon skipped transcript at lower doses and in a shorter period than other exon 51 therapies, approved or in development. We believe this indicates our Enhanced Delivery Oligonucleotide (EDO) technology is delivering greater levels of oligonucleotide to the nuclei. We are also very pleased PGN-EDO51 was well tolerated and that all patients experienced increases in dystrophin production. We look forward to our upcoming FREEDOM-DM1 clinical results update as we believe our EDO platform has the potential to dramatically improve the lives of people living with severe neuromuscular and neurological diseases."
Recent Program Highlights
PGN-EDO51: Duchenne Muscular Dystrophy (DMD)
Phase 2 CONNECT1-EDO51 Clinical Trial of PGN-EDO51: In July 2024, PepGen reported clinical data from the 5 mg/kg PGN-EDO51 dose cohort, including initial safety, exon 51 skipping, and dystrophin production data. CONNECT1 is a Phase 2, open-label, multiple ascending dose (MAD) clinical trial, being conducted in Canada, evaluating PGN-EDO51 in approximately 10 male patients at least 8 years of age with DMD amenable to an exon 51-skipping approach.
- At the 5 mg/kg Dose
- PGN-EDO51 was well tolerated by all study cohort participants through week 13. There were no discontinuations, dose interruptions or dose reductions.
- PGN-EDO51 produced mean exon skipping in biceps tissue of 2.15% at week 13 compared to baseline.
- PGN-EDO51 achieved a mean muscle-adjusted dystrophin level of 1.49% of normal and a 0.70% increase from baseline after 4 doses, measured at week 13.
- PGN-EDO51 achieved a mean absolute dystrophin level of 0.61% of normal and a 0.26% increase from baseline after 4 doses, measured at week 13 by Western blot analysis.
- The Company plans to present additional results from the 5 mg/kg cohort at a medical meeting later in the year.
- The Company expects to report initial results from the 10 mg/kg cohort of CONNECT1-EDO51 in early 2025.
Phase 2 CONNECT2-EDO51 Clinical Trial of PGN-EDO51: Based on the data from CONNECT1, including PGN-EDO51's emerging safety profile to date, the Company is working to optimize the design of the multinational CONNECT2 Phase 2 double-blind, placebo-controlled, MAD, 25-week trial. The CONNECT2 clinical trial is open in the United Kingdom. The Company continues to engage with regulators in the European Union and expects to open the clinical trial in the United States by year-end, subject to regulatory clearance.
PGN-EDODM1: Myotonic Dystrophy 1 (DM1)
- Phase 1 FREEDOM-DM1 Clinical Trial of PGN-EDODM1: PepGen anticipates reporting clinical results from the FREEDOM clinical trial, including safety, splicing correction, and functional outcome measures, in the fourth quarter of 2024. FREEDOM is a Phase 1 single ascending dose clinical trial evaluating PGN-EDODM1 in approximately 24 adult patients with DM1 in the United States, Canada, and the United Kingdom.
- Phase 2 FREEDOM2-DM1 Clinical Trial of PGN-EDODM1: PepGen is announcing today that both Health Canada and the United Kingdom Medicines and Healthcare products Regulatory Agency have cleared the Company's clinical trial application (CTA) submissions for the FREEDOM2 trial, and PepGen expects to initiate patient dosing in the second half of 2024. FREEDOM2 is a Phase 2 randomized, double-blind, placebo-controlled, MAD clinical trial evaluating PGN-EDODM1 in approximately 24 adult patients with DM1 in Canada, the United Kingdom, and in the United States, subject to regulatory clearance.
- PGN-EDODM1 Poster: In April 2024, PepGen presented a poster on the PGN-EDODM1 program at the 14th International Myotonic Dystrophy Consortium (2024 IDMC-14) Meeting.
- Poster title: FREEDOM-DM1: Phase 1 Study Design to Assess Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of PGN-EDODM1 for Myotonic Dystrophy Type 1.
The PGN-EDODM1 poster presented at the 2024 IDMC-14 Meeting is available on the Investors page of PepGen's website under Scientific Publications.
PGN-EDO53 (DMD)
- PepGen continues to advance PGN-EDO53 in investigational new drug (IND) and CTA enabling nonclinical studies.
Financial Results for the Three Months Ended June 30, 2024
- Cash, cash equivalents and marketable securities were $161.3 million as of June 30, 2024, which is anticipated to fund currently planned operations into 2026.
- Research and Development expenses were $25.1 million for the three months ended June 30, 2024, compared to $16.9 million for the same period in 2023.
- General and Administrative expenses were $5.4 million for the three months ended June 30, 2024, compared to $4.2 million for the same period in 2023.
- Net loss was $28.3 million, or $(0.87) basic and diluted net loss per share, for the three months ended June 30, 2024, compared to $19.5 million, or $(0.82) basic and diluted net loss per share, for the same period in 2023. PepGen had approximately 32.6 million shares outstanding on June 30, 2024.
About PGN-EDO51
PGN-EDO51, PepGen's lead clinical candidate for the treatment of Duchenne muscular dystrophy (DMD), utilizes the Company's proprietary Enhanced Delivery Oligonucleotide (EDO) technology to deliver a therapeutic phosphorodiamidate morpholino oligomer (PMO) 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 DMD patients, thereby aiming to restore the open reading frame and enabling the production of a truncated, yet functional dystrophin protein. The U.S. Food and Drug Administration has granted PGN-EDO51 both Orphan Drug and Rare Pediatric Disease Designations for the treatment of patients with DMD amenable to an exon-51 skipping approach.
About PGN-EDODM1
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, a key RNA splicing protein. DM1 is a progressively disabling, life-shortening genetic disorder. DM1 is estimated to affect 40,000 people in the United States, and over 74,000 people in Europe. The U.S. Food and Drug Administration has granted PGN-EDODM1 both Orphan Drug and Fast Track Designations for the treatment of patients with DM1.
