New York, Jan 26, 2026, 05:31 ET — Premarket
- Sarepta shares climb in early premarket, building on gains from late Friday after-hours trading
- Investors are focused on Monday’s update regarding Elevidys’ long-term trial results
- Durability and monitoring details remain central, guided by safety and label limits
Sarepta Therapeutics (SRPT.O) jumped roughly 6.5% to $22.51 in early Monday trading. The stock fluctuated narrowly between $22.51 and $22.57, with around 17,600 shares exchanging hands, according to data from Public.com. (Public)
The stock jumped 9.65% to $23.17 in after-hours trading Friday, driven by investor bets ahead of Sarepta’s upcoming update on its Duchenne muscular dystrophy gene therapy, according to RTTNews. Sarepta plans to release three-year “topline” functional data from Part 1 of EMBARK, its global, randomized, placebo-controlled Phase 3 trial of Elevidys in ambulatory children aged four to seven at treatment, the report noted.

Why it matters now: Sarepta faces pressure to deliver long-term functional data that will persuade doctors, regulators, and payers Elevidys is effective beyond early results. The stock’s been pricing in doubts about durability.
“Topline” results offer an initial snapshot of key outcomes. Investors usually see them as a directional guide, holding off until more detailed tables, subgroup analyses, and safety data come through.

Elevidys has been burdened by significant safety concerns. In November, the U.S. Food and Drug Administration updated its labeling to include a boxed warning, limiting Elevidys to ambulatory patients aged four and above after two non-ambulatory pediatric patients died from acute liver failure, Reuters reported. A spokesperson for Parent Project Muscular Dystrophy said the move highlighted that “serious questions remain” about the therapy’s safety and long-term effects. (Reuters)
Sarepta’s stock has swung sharply on trial updates. In early November, the company revealed a late-stage study for two other Duchenne drugs failed to hit its primary endpoint, pushing shares down over 37% in after-hours trading. J.P. Morgan analyst Anupam Rama cautioned that “regulatory processes can be a wild card,” according to Reuters.
On Monday, traders will zero in on the three-year functional trend lines, checking their alignment and consistency across patients. They’ll also watch closely for any new insights the company might share about monitoring or practical use.
This setup often triggers sharp moves in either direction. Pre-market prices tend to amplify the initial response, particularly with binary biotech events.
The risk is clear-cut: should the update suggest waning benefits, increased variability, or new safety concerns, initial gains might evaporate fast and regulatory disputes could reignite.
Coming up, the company’s webcast and conference call are set for 8:30 a.m. ET on Monday. Investors will be keen to see if Sarepta’s gains in premarket trading stick once the regular session begins. (RTTNews)
