NTI164と自閉症スペクトラム障害 (Beyond Harmony)

2026年9月27日 更新者：Fenix Innovation Group

自閉症スペクトラム障害を有する小児および若年成人におけるNTI164の有効性および安全性を検討する第III相二重盲検ランダム化プラセボ対照試験

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.

詳細な説明

Participants will be recruited from sites across Australia and will have a diagnosis of ASD Level II or III, as well as satisfying other inclusion/exclusion criteria. The primary objective is to assess efficacy of 16 weeks of daily oral administration of NTI164 on core ASD symptoms compared to placebo. The secondary objectives are to further expand the safety data of NTI164 in this patient cohort, and assess the changes in other associated symptoms of ASD following NTI164.

  15. Any history of suicidal behaviour (lifelong) or any suicidal ideation of type 4 or 5 on the Columbia-Suicide Severity Rating Scale (C-SSRS) in the last 12 weeks or at screening or randomisation.
  16. Participant has donated blood during the past 12 weeks and is unwilling to abstain from donation of blood during the trial.

The core domains sum to a total Adaptive Behaviour Composite. Scores are between 20-160, higher scores indicate better outcomes.

Baseline, Week 16
Clinical Global Impression - Severity (CGI-S)

メジャーの説明
時間枠
Research samples - transcriptomics
時間枠：Baseline, Week 16

To further clarify the mechanism of action of NTI164, both bulk and single-cell RNA sequencing will be performed on peripheral blood mononuclear cells (PBMCs) from patients at specified time points. This will provide additional information regarding which genes are being expressed in patients at either abnormally low or high levels compared to a non-ASD population, and the effects NTI164 has on gene expression. This workflow includes RNA extraction, depletion of ribosomal RNA via hybrid capture, library preparation, and sequencing. Cleaned sequence reads will then be aligned against the Homo sapiens genome (Build version hg38) and STAR aligner (v2.5.3a) will be used to map unique reads to the genomic sequences. This is exploratory so genes of interest cannot be identified in advance.
Baseline, Week 16
Research bloods - proteomics (and phosphoproteomics)
時間枠：Baseline, Week 16

To further clarify the mechanism of action of NTI164, proteomics and phosphoproteomics will be performed on peripheral blood mononuclear cells (PBMCs) from patients at specified time points. This will provide additional information regarding which proteins are being expressed at either abnormally low or high levels compared to a non-ASD population, as well as how extensively these proteins are phosphorylated compared to a non-ASD population, and the effects NTI164 has on protein expression and phosphorylation. Samples will be tagged using the TMTpro system and hydrophilic ion liquid chromatography fractionation performed. This is exploratory so proteins of interest cannot be identified in advance.
Baseline, Week 16
Research bloods - Methylomics
時間枠：Baseline, Week 16

To further clarify the mechanism of action of NTI164, methylomics will be performed on whole blood from patients at specified time points. This will provide additional information on methylation patterns (e.g. addition of a methyl group to histones or DNA) in patients compared to non-patients, and how NTI164 effects this type of epigenetic modification and how genes of interest may be regulated. This is exploratory so patterns of interest cannot be identified in advance. Genome-wide methylation will be assessed using the Illumina MethylationEPIC v2.0 BeadChip (or the latest version if a new version is available to the study team at the time of analysis).
Baseline, Week 16
Research bloods - cytokine assay
時間枠：Baseline, Week 16

To further clarify the mechanism of action of NTI164, a cytokine assay investigating a panel of inflammatory markers will be performed on plasma from patients at specified time points. The cytokine assay will likely be the LEGENDplex Human Neuroinflammation Panel 1 (13 plex). Cytokines investigated with this panel include VILIP-1, CCL2, sTREM-2, b-NGF, TGF-b1, TNF-a, IL-6, s-TREM-1, sRAGE, CX3CL1, VEGF, BDNF, and IL-18.
