PepGen Reports Third Quarter 2022 Financial Results and Recent Corporate Developments
PepGen Inc. (Nasdaq: PEPG) reported its Q3 2022 results, highlighting successful Phase 1 trial data for PGN-EDO51, indicating high levels of oligonucleotide delivery and exon skipping in DMD patients. With cash reserves of $195.8 million, R&D expenses rose to $16 million, which is significantly higher than last year's $5.7 million. The net loss increased to $18.6 million from $8.1 million year-over-year. Upcoming milestones include initiating Phase 2a trials for PGN-EDO51 and Phase 1/2 trials for PGN-EDODM1 in the first half of 2023.
- Phase 1 trial of PGN-EDO51 showed highest levels of oligonucleotide delivery and exon skipping compared to public data.
- Cash and cash equivalents at $195.8 million provide substantial runway for clinical trials.
- Upcoming Phase 2a trial of PGN-EDO51 and Phase 1/2 trial of PGN-EDODM1 in 2023 could enhance pipeline strength.
- Net loss increased to $18.6 million from $8.1 million year-over-year, indicating rising financial strain.
- Research and Development expenses surged to $16 million, reflecting increased clinical costs.
BOSTON, Nov. 10, 2022 (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, 2022 and highlighted recent corporate developments.
“During the third quarter we reported results from our Phase 1 Healthy Normal Volunteer (HNV) clinical trial of PGN-EDO51, our lead program for the treatment of Duchenne muscular dystrophy (DMD) patients who are amenable to an exon 51 skipping approach. These results exceeded our expectations, with PGN-EDO51 exhibiting the highest levels of oligonucleotide delivery and exon skipping in a clinical trial following a single dose when compared to publicly-available data,” commented James McArthur, Ph.D., President and CEO of PepGen. “PGN-EDO51 was generally well-tolerated, and we were particularly pleased to see consistently higher exon 51 skipping data observed at Day 28 compared to Day 10. We believe that this sustained pharmacodynamic activity observed in humans signals that PGN-EDO51 has the potential to drive accumulation of exon 51 skipped transcript and dystrophin protein in muscle following a repeat dosing regimen in people living with DMD, and we anticipate initiating a Phase 2a multiple ascending dose trial in patients in the first half of 2023.”
Dr. McArthur continued, “Alongside the success seen in our Phase 1 HNV trial, we’ve continued to further advance our Enhanced Delivery Oligonucleotide (EDO) portfolio of candidate therapeutics. We anticipate initiating a Phase 1/2 patient clinical trial of PGN-EDODM1, PepGen’s program for the treatment of myotonic dystrophy type 1 (DM1), in the first half of 2023, and, based on the results obtained in our Phase 1 trial of PGN-EDO51, we believe that PGN-EDODM1 has the potential to achieve tissue concentrations in DM1 patients that could lead to clinically meaningful outcomes. We also anticipate reporting non-human primate (NHP) data for PGN-EDO53, PepGen’s program for the treatment of DMD patients who are amenable to an exon 53 skipping approach, as well as nominating our lead investigational drug candidates for PGN-EDO45 and PGN-EDO44, for the treatment of DMD patients who are amenable to an exon 45 and exon 44 skipping approach, respectively, by the end of 2022.”
Recent Corporate Highlights
- In September, PepGen appointed Habib Dable to the Company’s Board of Directors. Mr. Dable is an industry veteran and former President and Chief Executive Officer of Acceleron Pharma where he led Acceleron’s first blockbuster launch in 2019, prior to its eventual sale to Merck & Co.
- In September, PepGen reported positive results from its Phase 1 HNV trial of PGN-EDO51 for the treatment of DMD patients whose mutations are amenable to an exon 51 skipping approach. The Phase 1 trial met its primary endpoint, providing evidence that PGN-EDO51 was generally well tolerated at pharmacologically relevant doses. A dose dependent increase in PGN-EDO51 tissue concentration and exon skipping was observed in HNV biceps:
- In the 10 mg/kg dose cohort, PGN-EDO51 exhibited mean oligonucleotide tissue concentrations of 19 nM and 11 nM in biceps biopsies taken at Day 10 (n=6) and Day 28 (n=6), respectively. In the same 10 mg/kg dose cohort, PGN-EDO51 exhibited mean exon skipping of
1.1% and1.4% in biceps biopsies taken at Day 10 (n=6) and Day 28 (n=6), respectively. All AEs observed at this dose level were mild.
- In the 10 mg/kg dose cohort, PGN-EDO51 exhibited mean oligonucleotide tissue concentrations of 19 nM and 11 nM in biceps biopsies taken at Day 10 (n=6) and Day 28 (n=6), respectively. In the same 10 mg/kg dose cohort, PGN-EDO51 exhibited mean exon skipping of
Based on cross-trial comparisons with publicly available data, PepGen believes that these results reflect the highest levels of exon skipping and oligonucleotide delivery observed in a clinical trial following a single dose when compared to publicly available clinical data for other exon 51 skipping approaches.
- In October, PepGen presented preclinical data from its lead DMD program at the 27th Annual Congress of the World Muscle Society. The poster presentation detailed findings that a single dose of PGN-EDO23, the murine analogue of PGN-EDO51, in the mdx DMD model achieved up to
93.1% exon skipping and99.7% dystrophin expression in skeletal muscle, and62.3% exon skipping and25.7% dystrophin expression in the heart. In non-human primates (NHPs), three doses of PGN-EDO51 achieved up to78% exon skipping in skeletal muscle and24% exon skipping in the left ventricle of the heart, with this repeat dosing regimen also demonstrating accumulation of exon 51 skipped transcript with successive doses in quadriceps and biceps.
Upcoming Anticipated Milestones
- PGN-EDO51: PepGen anticipates initiating a Phase 2a multiple ascending dose (MAD) trial evaluating PGN-EDO51 in DMD patients in the first half of 2023.
- PGN-EDODM1: PepGen anticipates initiating a Phase 1/2 clinical trial in DM1 patients in the first half of 2023.
- PGN-EDO53: PepGen anticipates reporting NHP exon skipping data by the end of 2022 for PGN-EDO53, the Company’s program for the treatment of DMD patients who are amenable to an exon 53 skipping approach.
- Additional Pipeline Assets: PepGen anticipates that it will nominate lead candidates for PGN-EDO45 and PGN-EDO44 by the end of 2022, which target DMD patient populations amenable to an exon 45 and exon 44 skipping approaches, respectively.
Financial Results for the Three Months Ended September 30, 2022
- Cash and cash equivalents were
$195.8 million as of September 30, 2022. - Research and Development expenses were
$16.0 million for the three months ended September 30, 2022, compared to$5.7 million for the same period in 2021. The increase in research and development expenses was primarily due to increases in preclinical, manufacturing and clinical costs associated with our Phase 1 trial for PGN-EDO51, as well as an increase in personnel-related costs. - General and Administrative expenses were
$3.6 million for the three months ended September 30, 2022, compared to$2.4 million for the same period in 2021. The increase in general and administrative expenses was primarily due to increased costs to support public company operations. - Net loss was
$18.6 million for the three months ended September 30, 2022, compared to$8.1 million for the same period in 2021. PepGen had approximately 23.6 million shares outstanding on September 30, 2022.
