Detailed Narrative
CEO Transition and Strategic Vision
Michael Severino, in his first earnings call as CEO, expressed confidence in Sarepta's position as a leader in Duchenne and rare disease innovation. He highlighted the company's scientific achievements, including exon skipping and ELEVIDYS, and the potential of its siRNA platform. Severino emphasized the financial strength to independently advance pipeline programs and the importance of upcoming milestones, including Cohort 8 data and siRNA program readouts, to clarify the company's growth trajectory.
Commercial Performance and ELEVIDYS Momentum
Total net product revenue for Q2 FY26 was $329 million, with ELEVIDYS contributing $98 million and the PMO franchise $231 million. ELEVIDYS performance was in line with expectations, showing improving quarter-over-quarter enrollment forms, signaling increasing demand. The company expanded its commercial footprint and deployed sales teams, resulting in a record number of healthcare provider interactions and broader site activity, reinforcing confidence in ELEVIDYS' benefit-risk profile.
Pipeline Progress in siRNA Programs
Sarepta remains on track to announce interim results from its Multi-Ascending Study (MAD) for SRP-1001 (FSHD) and SRP-1003 (DM1) in the second half of 2026. The siRNA platform is differentiated by biology-driven tissue targeting, efficient intracellular delivery, and catalytic siRNA potency. The company aims to achieve deep DUX4 knockdown in FSHD and DMPK knockdown in DM1, with preclinical models showing high muscle concentration and strong safety profiles, positioning these programs as potential best-in-class therapies.
Duchenne Regulatory Updates and ELEVIDYS Safety
The FDA accepted supplemental NDA submissions for AMONDYS 45 and VYONDYS 53, seeking conversion to traditional approvals with a target action date of February 28, 2027. Enrollment and dosing continue in Cohort 8 of the ENDEAVOR study for ELEVIDYS, assessing prophylactic sirolimus to reduce acute liver injury (ALI) in non-ambulant Duchenne patients. Interim safety data from the Phase 4 ENDURE study showed zero incidence of ALI in patients treated prophylactically with sirolimus.
Financial Strength and Capital Allocation
Sarepta delivered strong financial performance in Q2, with GAAP and non-GAAP operating profitability. Cash and investments increased by $197 million to $945 million. The company's disciplined cost management led to a 44% decrease in non-GAAP R&D and SG&A expenses year-over-year. Management reiterated its strong financial position, with the base business generating approximately $400 million in cash over the last 12 months, enabling independent funding of its promising pipeline.
EXONDYS 51 10-Year Anniversary
Sarepta celebrated the 10-year anniversary of EXONDYS 51's U.S. approval on September 19th. This milestone underscores Sarepta's leadership in Duchenne, establishing exon skipping as a foundational treatment approach. The company has built a substantial body of real-world evidence demonstrating benefits across ambulation, pulmonary and cardiac function, and survival, with over 1,800 patients treated worldwide with exon skipping therapies.
Huntington's Disease Program Progress
The CNS Huntington's program is ongoing, with the first patients dosed earlier this year. This program utilizes a transferrin receptor-based approach for blood-brain barrier delivery. Early proof of biology data is expected early next year, focusing on safety and knockdown of Huntington in the CSF, which would validate the platform's potential for CNS indications.
