BOSTON, Nov. 08, 2023 (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 third quarter ended September 30, 2023 and highlighted recent corporate developments.
“We made significant progress across our pipeline of Enhanced Delivery Oligonucleotide (EDO) candidate therapeutics in the third quarter of 2023, including positive news from regulatory authorities that enable the launch of our FREEDOM-DM1 study in the U.S. and Canada,” said James McArthur, Ph.D., President and CEO of PepGen. “We were pleased to have been cleared by the U.S. Food and Drug Administration (FDA) to conduct the FREEDOM-DM1 study at target dose levels, 5 mg/kg, 10 mg/kg, and 20 mg/kg, that we believe could benefit patients in a clinically meaningful way. In addition, we were happy to report that the FDA granted Orphan Drug Designation to PGN-EDODM1 for the treatment of myotonic dystrophy type 1 (DM1).”
Dr. McArthur added, “We also remain focused on continuing to advance our CONNECT1-EDO51 study evaluating PGN-EDO51 in Duchenne muscular dystrophy, and look forward to reporting dystrophin production, exon skipping and safety data following 4 monthly doses of PGN-EDO51 in mid-2024.”

About PepGen
PepGen Inc. is 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. PepGen’s Enhanced Delivery Oligonucleotide, or EDO, platform is founded on over a decade of research and development and leverages cell-penetrating peptides to improve the uptake and activity of conjugated oligonucleotide therapeutics. Using these EDO peptides, we are generating a pipeline of oligonucleotide therapeutic candidates that are designed to target the root cause of serious diseases.
About PGN-EDODM1
PGN-EDODM1 is an investigational candidate designed to deliver a peptide-conjugated antisense oligonucleotide (ASO) to restore cellular function. DM1 is caused by an expansion of CUG repeats that form hairpin loops in the DMPK RNA, resulting in sequestration of the MBNL1 protein, a key RNA processing factor. The sequestration of MBNL1 results in downstream mis-splicing events and aberrant expression of many proteins that play a critical role in muscle and other systemic functions (e.g. endocrine, gastrointestinal, central nervous system). By specifically blocking the toxic CUG repeats, the goal of PGN-EDODM1 is to liberate MBNL1 protein and to restore functional downstream splicing and muscle and other systemic functions.
About Myotonic Dystrophy Type 1 (DM1)
Myotonic dystrophy type 1, or DM1 (also known as Steinert’s disease), is a progressively disabling, life-shortening genetic disorder. DM1 is the most prevalent form of the disease and generally the most severe. DM1 affects an estimated 40,000 people in the U.S., and 70,000 in the EU. The average life expectancy for people living with DM1 is 45-60 years old. People living with DM1 typically present with myotonia (stiff or contracted muscles), muscle weakness, and cardiac and respiratory abnormalities. Many people living with DM1 also experience excessive daytime sleepiness, fatigue, and issues with gastrointestinal or cognitive dysfunction that significantly affect their quality of life.
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 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 DMD patients, thereby aiming to restore the open reading frame and enabling the production of a truncated, yet functional dystrophin protein. In preclinical studies, PepGen observed that treatment of non-human primates with PGN-EDO51 resulted in greater levels of exon-skipping when compared in head-to-head studies against a molecule that we believe is structurally equivalent to the most clinically-advanced peptide-conjugated oligonucleotide therapeutic candidate, which could translate to higher levels of dystrophin production in patients. PGN-EDO51 also exhibited the highest level of exon 51 skipping in primate skeletal muscles, including the diaphragm, reported for any approved therapeutic or known development candidate, based on cross-trial comparisons of publicly available data with preclinical PGN-EDO51 data. In humans, in a single ascending dose study, PGN-EDO51 also exhibited the 20-fold higher exon 51 skipping than naked oligo following a single dose, based on cross-trial comparisons of publicly available data with clinical PGN-EDO51 data.
About Duchenne Muscular Dystrophy (DMD)
Duchenne muscular dystrophy (DMD) is an X-linked recessive muscle-wasting disease that predominantly affects males. This debilitating disease is caused by genetic mutations in the gene encoding dystrophin, a protein critical for healthy muscle function, and is one of the most prevalent rare genetic diseases, with an incidence rate of approximately one in every 3,500 to 5,000 male births. DMD is characterized by progressive muscle weakness, which leads to patients losing the ability to walk, a loss of upper body function, cardiac issues and difficulties breathing. DMD is invariably fatal by young adulthood. Despite significant advances in treatments for this devastating disease, current therapies are limited by poor delivery to muscle tissue and have yet to establish meaningful clinical benefit for DMD patients.
