NTI-164

This 18-week open-label study examines the effectiveness of Full-Spectrum Medicinal Cannabis Plant Extract containing 0.08% THC (NTI164) in treating Rett syndrome (RTT) in children and young people. The study aims to determine the impact of NTI164 on RTT symptoms over a 16-week treatment period.
Participants will start with a daily dose of 5 mg/kg of NTI164, which will be gradually increased over four weeks until they reach either the maximum tolerated dose or 20 mg/kg per day. They will then maintain this dose for eight weeks. Following this treatment phase, the dosage will be reduced by 5 mg/kg each week for four weeks until treatment concludes.
The effectiveness of the treatment will be assessed using tailored questionnaires that measure changes in the patients' conditions. Additionally, full blood examinations will be conducted at multiple points throughout the study to monitor the effects of the treatment.
