The main purpose of this trial is to study the efficacy and safety of SOM3355 in patients with Huntington’s disease. SOM3355, which has been used for hypertension, will be looked at in this phase 2b trial to establish if it helps with chorea in HD. 2 doses and a placebo group will receive the drug orally twice a day for 12 weeks. 129 participants will be recruited.
Onset of HD symptoms prior to age of 21 years (juvenile forms of HD).
HD patients presenting rigid akinesia.
Use of other VMAT2 inhibitors such as tetrabenazine, deutetrabenazine, or valbenazine; and use of other antichoreic treatment such as any neuroleptic, or amantadine, memantine, riluzole.
Patients who experienced severe depression or suicide attempt in the last 5 years.
Severe untreated or under-treated psychiatric illness such as active suicidal ideation or behavior or depression.
Patients with a history of, or current, hypotension, bradycardia, or orthostatic hypotension.
Patients with hypertension already treated with more than 2 antihypertensive drugs.
Other active clinically significant illness, which could interfere with the study conduct, counter-indicate the study treatment, place the patient at risk during the trial, or compromise their study participation.
Any significant serious abnormality in the electrocardiogram (ECG), or a known history of long QTc syndrome.
Patients with severe hepatic impairment, or with severe renal impairment, or with any other significant abnormality in the physical examination or clinical laboratory results that, in the Investigator’s opinion, would not be compatible with study participation or represent a risk for the patient while in the study.
Females who are pregnant or lactating, or who intend to become pregnant during the study period.
Patients with allergy under desensitization, with known psoriasis, or a known allergy/hypersensitivity to any ingredients of the trial medication or placebo.
