Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults with manifest Huntington's disease exhibiting motor symptoms and genetic confirmation of the condition.
✕Probably not a fit
Patients with significant medical comorbidities or those who are pregnant or lactating may not benefit from this study.

What this trial studies
This trial evaluates the safety and tolerability of combined oral thiamine and biotin therapy in patients with mild to moderate Huntington's disease. The study aims to assess the biological effects of the treatment by measuring thiamine monophosphate levels in cerebrospinal fluid over a one-year follow-up period. Participants will undergo periodic clinical examinations and monitoring for adverse effects, alongside analytical assessments of thiamine levels in both cerebrospinal fluid and blood. The ultimate goal is to determine if this combination therapy can modify the disease course or slow symptom progression in early-stage Huntington's disease patients.
Why it matters
Potential benefit: If successful, this treatment could potentially slow the progression of Huntington's disease symptoms in early-stage patients.
How similar studies have gone: While this approach is novel, other studies have explored thiamine and biotin individually, but combined therapy in this context is less common.

Inclusion Criteria: * Patients of legal age with manifest Huntington's disease with motor symptoms (chorea, dystonia or bradykinesia) and/or neuropsychiatric; and genetic confirmation of a number of repetitions of the cytosine-adenine-guanine trinucleotide (CAG triplet) in the HTT gene (coding for HTT) greater than or equal to 39 * Patients should be capable of giving informed consent and attending the planned visit of the study. * Women of childbearing age should obtain a negative result in the serum or urine pregnancy test at the screening visit. They must also accept the use of appropriate contraceptive methods during the course of the clinical trial and men who have a partner of childbearing age, accept the use of contraceptive methods Exclusion Criteria: * Medical comorbidities considered clinically significant by the clinical judgment of the investigators. * Pregnancy or lactation * Patients with HD dependents on the basic routine daily life activities (UHDRS TFC \< 7) or a severe cognitive decline. * Active psychosis at the moment of the screening evaluation. * Severe renal failure. * Patients previously treated with thiamine and/or biotin or enrolled in other HD clinical trial with oligonucleotide antisense (IONIS-HTTRX (RG6042).
