World's first WWOX gene therapy performed on infant in Israel | The Jerusalem Post
- An eight‑month‑old with WOREE syndrome received an experimental WWOX gene therapy directly in the brain at Schneider Children’s Medical Center.
- The treatment was delivered at Schneider Children’s Medical Center of Israel in Petah Tikva as part of a compassionate‑use program.
- Researchers used an AAV9 vector to deliver a healthy copy of the WWOX gene to neurons, with preclinical studies supporting the concept.
- Mahzi Therapeutics is advancing the program toward clinical application and coordinating translational and regulatory activities.
- WWOX‑related epileptic encephalopathy causes early‑onset, drug‑resistant seizures and severe developmental impairment.
- Early follow-up showed no recurrence of severe seizures during the initial observation period after treatment.
- The program builds on HUJI research linking WWOX to nervous system development and function.
- The initial success is described as a milestone toward personalized therapies for rare genetic epilepsies.
- The infant's condition originated from a genetic defect common in Yemeni Jewish ancestry but with variants worldwide.
- The therapy represents a collaboration among Israeli and US scientists and regulatory partners.
