POLARIS Phase 1/2 Program Interim Safety and Preliminary Efficacy Results of ETX101, a One-Time Gene Regulation Therapy, in Young Children with Dravet Syndrome
(AES 2025)
- P1/2 | "Preliminary results from the POLARIS program demonstrate that ascending dose levels of ETX101 have been well-tolerated with no safety concerns related to study drug. Dose-dependent anti-seizure effects highlight the promising therapeutic potential of ETX101 and support continued development to establish its efficacy and long-term impact. Notably, this research represents the first clinical data for an investigational one-time, cell-type selective, gene regulation therapy, and the first potential one-time, disease-modifying treatment for DS."

Cell-selective AAV-mediated SCN1A Gene Regulation Therapy Rescues Mortality and Seizure Phenotypes in a Dravet Syndrome Mouse Model and is Well Tolerated in Non-human Primates.
(PubMed, Hum Gene Ther)
- "AAV9-RE-eTF was well tolerated, with no adverse events during administration, no detectable changes in clinical observations, no adverse findings in histopathology, and no dorsal root ganglion-related toxicity. Our results support the clinical development of AAV9-RE-eTF (ETX101) as an effective and targeted disease-modifying approach to SCN1A+ DS."
