This is a double-blind, randomised, placebo-controlled study investigating the efficacy of a full-spectrum medicinal cannabis plant extract on core and associated ASD symptoms over placebo. Participants will be randomly allocated to either NTI164 or placebo at a 1:1 ratio and blood samples will be collected and surveys completed at baseline and Week 16. This study will expand efficacy and safety data of NTI164 and provide additional mechanism of action data of NTI164 in this patient cohort.

The FENRTT2 study will investigate the efficacy and safety of a medicinal cannabis plant extract with extremely low THC (delta-9-tetrahydrocannabinol), NTI164, on Rett syndrome (RTT) in a crossover design. RTT is a devastating rare genetic condition affecting females and involves debilitating physical and intellectual symptoms. NTI164 is an oil which has demonstrated efficacy in reducing symptoms in several paediatric neurological conditions, including RTT, autism spectrum disorder (ASD), and paediatric acute-onset neuropsychicatric syndrome (PANS). A Phase I/II clinical trial of NTI164 in RTT (FENRTT1/NTIRTT1) showed NTI164 is safe in this population and significantly improved overall clinical severity of illness, as well as core RTT symptoms, including anxiety, mental alertness, communication skills, socialisation/eye contact, and attentiveness. The FENRTT2 study will investigate NTI164 in a larger number of patients, and compare NTI164 to a placebo control. Research tests on patient blood will also be included to further investigate how NTI164 works in the body.

This study is looking at how a new cannabis compound with extremely low THC (0.08%), NTI164, is metabolised in the body and how it is excreted in urine over time (up to 28 days) in healthy adult volunteers. NTI164 will be delivered twice daily, at a concentration of 20mg/kg/day. There will be 2 parts to this study, Part A and Part B. Part A involves only one day of taking NTI164, whereas Part B involves taking NTI164 for 7 consecutive days. Urine samples and blood samples will be collected at certain time points after NTI164 dosing to help characterise how the drug is being broken down in the body and over what time frame.
