Pridopidine Phase 3 Study in Huntington's Disease (PRECISE-HD)
A Phase 3, Randomized, Double-blind, Placebo-controlled Study to Evaluate the Efficacy and Safety of Pridopidine in Participants With Huntington's Disease (HD)
The goal of this clinical trial is to learn if pridopidine can slow the clinical decline of Huntington's Disease (HD) in adult participants. It will also inform about the safety of pridopidine.
The main questions the study aims to answer are:
Does pridopidine slow the overall worsening of HD over 1 year? Does pridopidine slow the worsening of specific aspects of HD over 1 year, namely the clinical progression, the ability to perform daily life activities (functional capacity), the mind's ability to process information (cognition), working of the muscles (motor function), and quality of life?
Researchers will compare the drug pridopidine to a placebo (a look-alike substance that contains no drug) to see if pridopidine works better than placebo to treat HD. During the first year of the study, participants will have the same chance to receive either pridopidine or placebo.
Participants will:
Take 1 pridopidine or placebo capsule twice daily for 12 months. Visit the clinic 6 times within 1 year for checkups and tests.
All participants who complete this 1-year placebo-controlled study period will roll over into an additional 2-year study period during which all participants will receive pridopidine treatment, including participants who had received placebo during the first year. During this additional 2-year treatment period participants will visit the clinic a total of 6 times for checkups and tests.

Descrizione dettagliata
This Phase 3 study consists of two study periods, a randomized, double-blind, placebo-controlled 1-year study period and a 2-year open-label extension (OLE) period. The study assesses the effect of pridopidine 45 mg twice daily on HD in participants who are not using antidopaminergic medications (ADMs) at study start. Main objectives of the study will be to assess the effect of pridopidine on clinical progression of HD within 1 year and to evaluate the effect of pridopidine on functional capacity, cognition, motor function, quality of life (QoL), and speech in participants with HD within 1 year.
The target population in this study are adult participants (age 23-65, inclusive) with adult-onset HD (onset of signs and symptoms and a diagnosis ≥21 years of age). Eligible participants have not been using ADMs for at least 6 months prior to the screening visit. In case ADM treatment is deemed necessary by the treating physician during the study, specific ADMs and doses may be initiated. Female participants who are pregnant, planning to become pregnant or breastfeeding are not allowed to enter the study.
The treatment period will start with a 2-week titration period of once-daily treatment (1 capsule of pridopidine or placebo taken orally in the morning). From Day 15 onwards, all participants will take the study drug twice daily: in the morning and in the afternoon. Treatment will continue for an additional 50 weeks.
The placebo-controlled study period includes 6 in-clinic visits and 5 telephone visits (safety calls) during the 1-year treatment period.
The placebo-controlled study period will be followed by a 2-year OLE period. During the OLE period, all eligible participants will receive pridopidine. The OLE will consist of a 2-year treatment period, including an initial 2-week (re)titration period for all participants at pridopidine once daily and a maintenance period of 102 weeks with pridopidine twice daily. The blinding of the original treatment assignment will be maintained for all participants and study personnel during the OLE period.
A total of 6 in-clinic visits and 6 telephone visits (safety calls) are planned during the 2-year OLE period.

Change in Composite Unified Huntington's Disease Rating Scale (cUHDRS)
Lasso di tempo: Change from Baseline to Week 52
|
cUHDRS is a combined score to assess disease progression in HD. It includes TFC, TMS, SDMT, and SWR: Total Functional Capacity (TFC) tests the capacity to maintain daily living, finances, care level, occupation. Higher score = better outcome. Best score=13. Worst score=0. Total Motor Score (TMS) assesses motor features (oculomotor, dysarthria, chorea, dystonia, gait, postural stability). Higher score = worse outcome. Best score=0. Worst score= 124. Stroop Word Reading (SWR) measures attention and mental flexibility. Participant reads names of colors printed in black ink. Scores reflect correct responses in 45 sec. Higher score = better outcome. Best score=100. Worst score=0. Symbol Digit Modalities Test (SDMT) tests psychomotor speed and working memory. Participant has 90 sec to match numbers with symbols. Scores = correct answers in 90 sec. Higher score = better outcome. Best score=120. Worst score=0. Total integrated cUHDRS scale range: -7.6 to 24.8. The higher, the better. |
