PepGen Announces Regulatory Updates on FREEDOM2
MWN-AI** Summary
PepGen Inc. (Nasdaq: PEPG) recently announced significant updates regarding its FREEDOM2 trial for PGN-EDODM1, an investigational treatment for myotonic dystrophy type 1 (DM1). The U.S. Food and Drug Administration (FDA) has placed a partial clinical hold on the FREEDOM2-DM1 Phase 2 study due to questions pertaining to preclinical pharmacology and toxicology findings, although the hold does not affect previously submitted blinded data from the earlier FREEDOM study. PepGen is actively working with the FDA to resolve these issues and is submitting additional analyses to address the agency's concerns.
Notably, PepGen has received regulatory clearance to initiate the FREEDOM2 trial in South Korea, Australia, and New Zealand. As recommended by the Data Safety Monitoring Board, the trial is currently progressing with a 10 mg/kg dosing cohort in Canada and the UK. Importantly, no patients have yet been enrolled from the U.S. PepGen also confirmed that patients involved in the FREEDOM and FREEDOM2 trials in Canada are transitioning into the Open Label Extension study, which will soon be available in regions where FREEDOM2 is conducted.
The company maintains its timeline for reporting data from the FREEDOM2 trial, with results from the 5 mg/kg cohort expected in Q1 2026 and the 10 mg/kg cohort anticipated in the second half of 2026. PGN-EDODM1 leverages PepGen's proprietary Enhanced Delivery Oligonucleotide (EDO) technology aimed at restoring normal splicing function in the MBNL1 RNA splicing protein, addressing the detrimental impacts of the CUG repeat expansion associated with DM1.
PepGen has received both Orphan Drug and Fast Track Designations for PGN-EDODM1 by the FDA, along with Orphan Designation from the European Medicines Agency, underscoring the potential significance of this innovative therapeutic approach.
MWN-AI** Analysis
PepGen Inc. (Nasdaq: PEPG) has recently announced pivotal regulatory updates surrounding its FREEDOM2 trial, substantially impacting its market positioning. The U.S. FDA's partial clinical hold raises concerns about preclinical pharmacology and toxicology, signaling caution for investors. However, PepGen has received regulatory clearance to advance the FREEDOM2 study in multiple international markets including South Korea, Australia, and New Zealand. This geographical diversification may serve as a buffer against the setbacks in the U.S. market.
Investors should closely monitor the company’s progress, particularly as dosing at the 10 mg/kg cohort continues in Canada and the UK. No U.S. patients are currently enrolled, which could mean limited early-stage data from the United States. The lack of adverse findings in Phase 1 trial data, however, bodes well for investors looking for long-term potential as PepGen maintains its schedule, projecting to present data from the 5 mg/kg cohort by Q1 2026 and the 10 mg/kg cohort in 2H 2026.
Despite the challenges posed by the FDA hold, PepGen’s innovative EDO technology offers profound promise in addressing the underlying causes of myotonic dystrophy type 1 (DM1), positioning it favorably within a niche but growing market for neuromuscular therapies. This technology may also reignite investor confidence as data becomes available, especially given the acceptance of its Orphan Drug and Fast Track Designations.
Thus, while caution is advised in the short term due to regulatory hurdles, the potential for strong long-term rewards suggests investors should consider accumulating shares, particularly as new data emerges and the international pipeline expands. Close monitoring of ongoing FDA interactions and trial results will be critical in the coming months.

- U.S. FDA places FREEDOM2 trial on partial clinical hold related to preclinical pharmacology and toxicology -
- Received regulatory clearance to initiate FREEDOM2 in South Korea, Australia, and New Zealand and dosing of the 10 mg/kg cohort continues in the UK and Canada -

PepGen Inc. (Nasdaq: PEPG), a clinical-stage biotechnology company advancing the next generation of oligonucleotide therapies to treat severe neuromuscular and neurological diseases, today announced regulatory updates related to the FREEDOM2 trial.
The U.S. Food and Drug Administration (FDA) has placed a partial clinical hold on the FREEDOM2-DM1 Phase 2 multiple ascending dose (MAD), randomized, placebo-controlled clinical trial of PGN-EDODM1 in patients with myotonic dystrophy type 1 (DM1). The partial clinical hold questions raised by FDA relate to previously submitted preclinical pharmacology and toxicology studies. The partial clinical hold did not cite any questions regarding blinded clinical data from the Phase 1 FREEDOM study previously submitted to the FDA in order to initiate the FREEDOM2 study in the U.S. As part of its ongoing dialogue with the FDA, the Company is submitting additional analyses, including the recently unblinded FREEDOM data, and is committed to working with the FDA to address their questions as quickly as possible.
PepGen was recently cleared to open the FREEDOM2 study in New Zealand, Australia, and South Korea.
Following the Data Safety Monitoring Board’s recommendation to dose escalate, the FREEDOM2 trial is dosing patients at 10 mg/kg in Canada and the UK. No U.S. patients have been enrolled in FREEDOM2. Patients from the FREEDOM and FREEDOM2 studies in Canada are continuing into the Open Label Extension (OLE) study. The Company has received regulatory clearance for the OLE study in the UK and intends to open the OLE study in all geographies where FREEDOM2 is open.
The Company expects to report data from the 5 mg/kg cohort of FREEDOM2 in the first quarter of 2026, and from the 10 mg/kg cohort in the second half of 2026.
About PGN-EDODM1
PGN-EDODM1, PepGen's 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. PGN-EDODM1 addresses the deleterious effects of cytosine-uracil-guanine (CUG) repeat expansion in the dystrophia myotonica protein kinase (DMPK) transcripts which sequester MBNL1, by binding to the pathogenic CUG trinucleotide repeat expansion present in the DMPK transcripts, and disrupting the binding between the CUG repeat expansion and MBNL1. PepGen believes this innovative therapeutic approach may have considerable advantages over oligonucleotide modalities that rely on knockdown or degradation of the DMPK transcripts as it will allow the DMPK transcripts to continue to perform their normal function within the cell, while also liberating MBNL1 to correct downstream mis-splicing events. 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. The European Medicines Agency (EMA) has recently granted Orphan Designation for PGN-EDODM1.
