FREEDOM2 10 mg/kg cohort readout in 2H 2026 • 2026-10-15

Expected move: -7%

Biggest risk

This remains a low-coverage, clinical-stage story with a U.S. partial hold, mixed 5 mg/kg biomarker efficacy that depended heavily on excluding an outlier, a single core clinical asset, and substantial downside if 10 mg/kg data do not clearly improve or the hold lingers [#IR-2026-03-04][#8-K-2026-03-30].

Invalidation

Break below $1 or thesis failure.

What would change my mind?

The stock is depressed versus its prior biotech valuation range, the 5 mg/kg FREEDOM2 data were clean on safety, ex-U.S. enrollment/dosing continues despite the U.S. partial hold, and a cleaner 10 mg/kg efficacy signal could drive a sharp re-rate from a low base [#8-K-2026-03-30].

Commentary

This is best framed as a cautious monitoring biotech setup, not a clean bullish thesis. Primary sources support two things at once: PepGen still has an active ex-U.S. trial, runway, and a defined 10 mg/kg readout path, but the U.S. partial hold and only modest disclosed 5 mg/kg efficacy keep conviction capped. Direct same-indication peers now look clearer, but the deterministic prior is still negative and that fits the current risk-reward until the next regulatory or clinical proof point arrives.

FREEDOM2 10 mg/kg cohort readout in 2H 2026
PepGen said the 10 mg/kg FREEDOM2 cohort is actively dosing, was more than halfway enrolled as of March 30, 2026, and remains on track for a second-half 2026 data readout after the 5 mg/kg cohort showed favorable safety with mixed but directionally positive biomarker/functional signals [#8-K-2026-03-30].

Short-term Catalysts

Next few weeks

FDA partial clinical hold resolution remains the key swing factor
2026-09-30
The main near-term overhang is the FDA partial clinical hold on FREEDOM2 tied to preclinical pharmacology and toxicology questions; PepGen said no U.S. patients were enrolled, ex-U.S. dosing continues, and the company is submitting additional analyses to address FDA questions [#IR-2026-03-04][#10-K-2026-03-04].
Prob 35% • Move 40% • Priced-in 25%

Long-term Catalysts

Months to a year

Runway into 2H 2027 limits immediate financing pressure
2027-07-01
PepGen reported $148.5 million of cash, cash equivalents, and marketable securities at December 31, 2025 and guided that this should fund currently planned operations into the second half of 2027, which helps preserve time for FREEDOM2 and OLE execution before another capital raise becomes unavoidable [#10-K-2026-03-04].
Prob 75% • Move 15% • Priced-in 65%

Risks

10 mg/kg FREEDOM2 data may fail to show clearly improved splicing or functional benefit versus the 5 mg/kg cohort.
Cash runway extends into 2H 2027, but a delayed or disappointing readout could still force dilutive financing before any major de-risking.
FDA partial clinical hold on FREEDOM2 may persist longer than expected or broaden.
PepGen is effectively a single-lead-asset biotech, so negative PGN-EDODM1 updates would hit the equity disproportionately.

Peers

Symbol	Summary
RNA	Avidity is a direct DM1 operating comparator because PepGen identifies del-desiran/AOC 1001 as a Phase 3 clinical program competing against PepGen's DM1 candidate, making RNA the clearest category benchmark for speed and perceived efficacy leadership [#10-K-2026-03-04].
TRDA	Entrada is a direct DM1 peer because PepGen lists VX-670, developed with Vertex, as a Phase 2 DM1 program, giving PepGen a third clinically active same-indication comparator beyond the broader small-cap biotech universe [#10-K-2026-03-04].
