Trial design
CTIS Part I — objectives, methods, condition coding
Main objective
Scope: Others
Identify biomarkers, used singly or in combination, that enable sensitive measurement of the progression of Huntington's disease from the presymptomatic stages onwards, within the framework of clinical trials.
Secondary objectives 2
- Identify patient profiles and HD progression trajectories (unsupervised analyses)
- Identify the best predictive biomarkers, individually or in combination, and establish their prognostic value on disease progression (supervised analyses)

- Intercurrent illness that may impact participant's performance
- Chronic progressive neurological disease
- Claustrophobia
- Brain injury unrelated to HD
- Pacemaker, intracorporeal metal, intracerebral clip, any metallic foreign body: implantable cardiac electronic device such as pacemakers, implantable cardioverter defibrillators etc., metallic intraocular foreign bodies, implantable neurostimulation systems, cochlear implants/ear implants, drug infusion pumps (insulin administration, analgesic drugs), or chemotherapy pumps): if possible, the patient should remove the device.
- Catheters with metal components (Swan-Ganz catheter), metal fragments such as bullets, shotgun pellets and metal shrapnel, cerebral artery aneurysm clips, magnetic dental implants, tissue expander, artificial limb, hearing aid, piercing such as pacemaker

- Person participating or having participated in a research protocol with a radiopharmaceutical injection for less than 12 months.
Endpoints
Primary and secondary outcome measures (English text)
Primary endpoints 1
- The primary endpoint will be effect size, assessed by the standardized mean difference (Cohen's d) for each biomarker between the values measured initially and their assessment at 2-year follow-up.
Secondary endpoints 2
- Analysis of patient profiles and progression trajectories, taking into account all available data at D0, M1, M1 bis, M12, M24 and M24 bis, will be based on socio-demographic characteristics, as well as initial clinical and paraclinical scores and their evolution over time. Clustering analyses will use statistical validation indices to determine the optimal number of clusters and provide information on cluster quality.
- Identification of the best biomarkers predicting an unfavorable disease course will be carried out using conventional regression and machine learning methods. Discrimination and calibration performances will be systematically evaluated and compared for each of the models constructed.
