Sarepta Therapeutics, Inc. Q3 FY25 Results

While the ESSENCE study did not meet statistical significance on its primary endpoint, we believe the results demonstrated a clear treatment effect, showing clinically meaningful functional outcomes for people with Duchenne who have mutations amenable to skipping exons 45 or 53. These topline findings reinforce the potential impact of these therapies to slow muscle weakness and other symptoms. The results of the study are consistent with the growing body of real-world evidence accumulated over several years. These data, which we have shared with the FDA, strengthen our confidence in the benefit of added dystrophin over time. This trial enrolled an ultra-rare subset of eligible Duchenne patients. The complexity of Duchenne, combined with the heterogeneity of the population and the impact of the COVID pandemic on participation, made this an extraordinary undertaking. We are deeply grateful to the families and investigators whose dedication made this possible, and we remain committed to advancing care for the Duchenne community by delivering options that can change the course of Duchenne.”

We are pleased to have met our primary post-marketing obligation with the completion of ESSENCE, a particularly challenging trial to execute in the context of these ultra-rare diseases that heterogeneously degenerate over the course of decades. We look forward to discussing the ESSENCE results and the real-world evidence for AMONDYS 45 and VYONDYS 53 with the FDA. We are also pleased to report solid performance in the quarter from our gene therapy, ELEVIDYS, and our three PMOs, EXONDYS 51, VYONDYS 53 and AMONDYS 45. Our net product revenue stood at $370.0 million for the quarter. Additionally, having taken steps to bolster our financial position, including the refinancing of our convertible debt and a significant financial restructuring, I am pleased to report positive cash flow in the quarter. Looking forward, we have a strong financial position from which to continue to serve our community as we advance a very exciting siRNA portfolio.”

In the trial and my clinical practice, I’ve followed boys and young men treated with casimersen and golodirsen since their initial approvals and, in my opinion, these therapies can help preserve critical functions like walking, stair climbing and feeding themselves. Over time, these gains can translate into a delayed loss of ambulation and even slower respiratory decline, potentially offering these individuals a meaningful path to maintaining quality of life.
