With funding in place through the 10 and 12.5 mg/kg cohorts, we are well positioned to continue dose escalating and deliver on the promise of this program for the DM1 community." Recent Program Updates PGN-EDODM1: Myotonic Dystrophy Type 1 (DM1) FREEDOM2 Phase 2 Multiple Ascending Dose (MAD) Randomized, Placebo-Controlled Clinical Trial of PGN-EDODM1: PepGen reported promising topline results from the 5 mg/kg MAD cohort, demonstrating favorable safety, splicing and vHOT data. The Company believes the totality of safety and efficacy results support the potential of PGN-EDODM1 in the ongoing 10 mg/kg dose cohort. Read the full release here. The Company has fully enrolled the 10 mg/kg MAD cohort of FREEDOM2. PepGen expects to report data from this cohort in the second half of 2026, with data from the 12.5 mg/kg cohort anticipated in 2027. PepGen has currently enrolled 13 patients in the open label extension (OLE) at 5 mg/kg, including 6 patients from FREEDOM2, with no patient discontinuations. The Company has received regulatory clearance to initiate the FREEDOM2 trial in South Korea, Australia, and New Zealand. Sites are currently open and active in Canada, the UK and South Korea, with plans to open sites in New Zealand and Australia. The U.S. Food and Drug Administration (FDA) placed a partial clinical hold on the FREEDOM2 study. The partial clinical hold questions raised by the FDA relate to previously submitted preclinical pharmacology and toxicology studies. The timing of the ongoing FREEDOM2 clinical study has not been impacted. The Company continues to work with the FDA to address the Agency’s questions as quickly as possible. Financial Results for the Three Months Ended March 31, 2026 Cash, Cash Equivalents and Marketable Securities were $132.3 million as of March 31, 2026. Based on currently planned operations, the Company believes that its existing cash, cash equivalents, and marketable securities will be sufficient to fund its operations into the second half of 2027. Research and Development Expenses were $13.0 million for the three months ended March 31, 2026, compared to $25.4 million for the same period in 2025. General and Administrative Expenses were $5.9 million for the three months ended March 31, 2026, compared to $5.9 million for the same period in 2025. Net Loss was $17.8 million, or $(0.26) basic and diluted net loss per share, for the three months ended March 31, 2026, compared to $30.2 million, or $(0.92) basic and diluted net loss per share, for the same period in 2025. PepGen had approximately 69.2 million shares outstanding on March 31, 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. About Myotonic Dystrophy Type 1 (DM1) Myotonic dystrophy type 1 (DM1) is a rare, progressive, and highly variable genetic neuromuscular disease caused by an abnormal expansion of cytosine-thymine-guanine (CTG) repeats in the dystrophia myotonica protein kinase (DMPK) gene. DM1 affects over 115,000 individuals in the U.S. and EU and is characterized by widespread, multisystem symptoms that may include myotonia, progressive muscle weakness, fatigue, cardiac abnormalities, respiratory impairment, and cognitive dysfunction. The disease is driven by toxic RNA transcripts containing expanded cytosine-uracil-guanine (CUG) repeats that sequester muscleblind-like 1 (MBNL1), a key RNA splicing protein, leading to widespread mis-splicing across multiple tissues. There are currently no approved disease-modifying therapies for DM1, underscoring the significant unmet medical need for patients living with the disease. About PepGen PepGen Inc. is a clinical-stage biotechnology company developing the next generation of oligonucleotide therapies with the goal of transforming the treatment of severe neuromuscular and neurological diseases. PepGen’s Enhanced Delivery Oligonucleotide (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, the Company is generating a pipeline of oligonucleotide therapeutic candidates designed to target the root cause of serious diseases.

– Conference call scheduled today at 4:30 p.m. ET –


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 announced promising clinical data from the 5 mg/kg multiple ascending dose cohort (MAD) of the ongoing Phase 2 FREEDOM2-DM1 trial in patients with myotonic dystrophy type 1 (DM1). The Company believes the totality of safety and efficacy results support the potential of the ongoing 10 mg/kg dose cohort, with clinical results expected in the second half of 2026.


“We are excited to share data from the lowest dose cohort in our multiple ascending dose study of PGN-EDODM1 in patients with DM1,” said Paul Streck, MD, EVP Research and Development. “Overall, we are encouraged by the favorable safety and tolerability profile, and the positive trends exhibited with splicing improvement and vHOT. We look forward to reporting data from the ongoing 10 mg/kg multiple ascending dose cohort of FREEDOM2, which is more than halfway enrolled and remains on track to read out in the second half of this year.”


FREEDOM2 Results for the 5 mg/kg (n=8) Dose Cohort


FREEDOM2 is a Phase 2 MAD, randomized, placebo-controlled clinical trial evaluating PGN-EDODM1 in patients with DM1, with planned dose escalation up to 12.5 mg/kg. The 5 mg/kg cohort enrolled eight patients, who received PGN-EDODM1 or placebo (randomized 6:2) every four weeks over a 12-week period. Key endpoints include safety, splicing correction and functional outcome measures. The data cutoff was March 4, 2026.


Splicing, Muscle Tissue Concentration and Functional Data:



Patients (n=6) treated with PGN-EDODM1 at 5 mg/kg demonstrated a mean splicing correction of 7.3%, compared to 6.8% in placebo-treated patients (n=2).


Excluding an outlier, patients showed a mean splicing correction of 22.9%. The outlier patient exhibited a worsening in splicing correction (70.8%), reducing the overall group mean to 7.3%.






Middle finger vHOT in the treatment group showed a positive trend of improvement versus a worsening observed in the placebo group. Both returned to baseline at Week 16.



Mean muscle tissue concentrations of PGN-EDODM1 available in 5 of 6 treated patients were 158 ng/g, as measured approximately one week after the fourth dose in the MAD study; one concentration readout remains pending.



No meaningful improvements were observed in 10-meter walk/run test (10MWRT) or handgrip strength at the starting PGN-EDODM1 dose of 5 mg/kg.



Safety and Tolerability Data:



PGN-EDODM1 was generally well-tolerated, with no serious adverse events (SAEs), all related treatment emergent adverse events (TEAEs) reported as mild and non-related TEAEs reported as mild or moderate



Nausea was the most common TEAE



No treatment-related discontinuations



No TEAEs related to renal function and no signs of cumulative toxicity



The Company is actively dosing the 10 mg/kg MAD cohort of FREEDOM2, with 5 of 8 patients receiving up to three doses of PGN-EDODM1, and expects to report data in the second half of 2026. In addition, 12 patients have currently enrolled in the open label extension (OLE) at 5 mg/kg, including 5 patients from FREEDOM2.

Original: PepGen Announces Regulatory Updates on FREEDOM2

PepGen Reports Fourth Quarter and Year-End 2025 Financial Results and Recent Corporate HighlightsMarch 4, 2026 4:05 PM
Business Wire
– FREEDOM2-DM1 5 mg/kg cohort data expected in Q1 2026 –


– Patient dosing in the FREEDOM2 10 mg/kg cohort is proceeding in Canada and the UK, with data expected in 2H 2026 –


– FREEDOM2 trial open in South Korea, Australia, and New Zealand –


– Well-funded with $148.5M of cash as of December 31, 2025, sufficient to fund operations into the second half of 2027 –


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 quarter and year-ended December 31, 2025, and recent corporate highlights.


“2025 was a transformative year for PepGen as the Phase 1 FREEDOM trial delivered compelling data that set a new benchmark for splicing correction in DM1, reinforced our conviction in PGN-EDODM1 as a potential best-in-class treatment, and further demonstrated the differentiated potential of our EDO platform," said James McArthur, PhD, President and Chief Executive Officer of PepGen. “After a single dose, we observed robust target engagement beginning at the lowest dose of 5 mg/kg — a finding that exceeded our expectations and underscored the potency of our drug candidate. PGN-EDODM1 was generally well-tolerated across doses, and based on the totality of FREEDOM data, we believe that doses of 10 mg/kg could potentially offer a best-in-class treatment option for people living with this serious disease.”


Dr. McArthur continued: “As we prepare for the 5 mg/kg dose cohort readout from our ongoing randomized, placebo-controlled multiple ascending dose Phase 2 FREEDOM2 study later this quarter, we are focused on building upon the robust muscle oligonucleotide levels and splicing correction observed in FREEDOM, with the goal of translating sustained exposure into meaningful functional benefit. Following the Data Safety Monitoring Board’s recommendation to dose escalate, we are actively dosing the 10 mg/kg cohort in FREEDOM2 – four patients have been dosed, receiving up to two doses. PepGen is entering this new year with strong momentum and a clear path toward potentially delivering a meaningful new treatment for the DM1 community.”


Recent Program Updates


PGN-EDODM1: Myotonic Dystrophy Type 1 (DM1)



FREEDOM2 Phase 2 Multiple Ascending Dose (MAD) Randomized, Placebo-Controlled Clinical Trial of PGN-EDODM1:


The Company expects to report results from the 5 mg/kg cohort of the FREEDOM2 trial in the first quarter of 2026.



After reviewing safety data from the 5 mg/kg cohort, the Data Safety Monitoring Board (DSMB) recommended escalating to the 10 mg/kg dose. PepGen has since dosed 50% of patients (4/8) in the 10 mg/kg cohort with up to two doses. The Company remains on track to report results from the 10 mg/kg cohort in the second half of 2026.



Informed by the prior FREEDOM results, PepGen has amended the FREEDOM2 protocol to provide the option to dose up to 12.5 mg/kg.



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 has recently received regulatory clearance to initiate the FREEDOM2 trial in South Korea, Australia, and New Zealand. Sites are currently enrolling in Canada, the UK and South Korea, with plans to open sites in New Zealand and Australia.



The U.S. Food and Drug Administration (FDA) has placed a partial clinical hold on the FREEDOM2 study. 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. The Company is committed to working with the FDA to address the Agency’s questions as quickly as possible.







Other FREEDOM Updates:


In October 2025, PepGen’s data were featured in two oral presentations at the 30th Annual International Congress of the World Muscle Society (WMS). One presentation included previously reported positive FREEDOM-DM1 Phase 1 clinical data.



In October 2025, the Company gave an oral presentation at the Oligonucleotide Therapeutics Society (OTS) Annual Meeting. The presentation reviewed the use of its Enhanced Delivery Oligonucleotide (EDO) Platform to develop a treatment for DM1 and included a review of the FREEDOM clinical data.






2026 MDA Conference Update


The Company will present unblinded final results from FREEDOM-DM1 — its Phase 1, placebo-controlled single ascending dose study of PGN-EDODM1 in DM1 adult patients — in oral and poster presentations at the 2026 Muscular Dystrophy Association (MDA) Clinical & Scientific Conference, being held March 8–11, 2026 in Orlando, Florida.


Key study findings include:


Efficacy: PGN-EDODM1 demonstrated greater than dose-proportional increases in muscle tissue concentration and splicing correction across all doses at Day 28. Mean splicing correction reached unprecedented levels after a single dose, achieving 12.3%, 29.1%, and 53.7% at 5 mg/kg (n=6), 10 mg/kg (n=5), and 15 mg/kg (n=6), respectively.


Safety: PGN-EDODM1 was generally well-tolerated across all doses; treatment-emergent adverse events (TEAEs) were mild to moderate, transient, and required no intervention (except one patient in the 15 mg/kg cohort, managed with oral antihistamines). No electrolyte-related TEAEs were observed, and magnesium levels remained within normal range across all doses. No renal biomarker-related TEAEs were observed at 5 or 10 mg/kg. Post-unblinding, transient moderate albuminuria increases at the 15 mg/kg dose and transient mild albuminuria increases at 10 mg/kg were apparent — both resolving to normal within two to seven days with no clinical symptoms or need for intervention.


Following the conference, the presentations presented at the 2026 MDA Clinical & Scientific Conference will be available on PepGen’s website under Scientific Publications.


Corporate Updates



In December 2025, PepGen appointed Joseph Vittiglio, Esq., as Chief Business and Legal Officer. Mr. Vittiglio brings more than two decades of executive leadership experience across legal, compliance, corporate development, and corporate governance within public biotechnology companies. He joins PepGen after providing consulting support to the Company in 2025.



In November 2025, the Company announced that the United States Patent and Trademark Office (USPTO) has issued the Company a new composition of matter patent covering PGN-EDODM1, which leverages PepGen’s proprietary EDO platform, including its unique peptide and linker chemistry. This newly issued composition of matter patent, which serves as a cornerstone of the Company’s expanding patient portfolio, is expected to provide exclusivity for PGN-EDODM1 in the United States into second half of 2042, with the possibility of patent term extension following a potential new drug application and approval by FDA of PGN-EDODM1.



Financial Results for the Three Months and Year Ended December 31, 2025



Cash, Cash Equivalents and Marketable Securities were $148.5 million as of December 31, 2025. Based on currently planned operations, the Company believes that its existing cash, cash, equivalents, and marketable securities will be sufficient to fund its operations into the second half of 2027.



Research and Development Expenses were $13.9 million for the three months ended December 31, 2025, compared to $19.0 million for the same period in 2024.

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.
