Huntington Disease
Conditions
Brief summary
This is a Phase 1b/2a multicenter, randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of WVE-003 in adult patients with early-manifest HD who carry the targeted single nucleotide polymorphism (SNP) - SNP3.
Interventions
Single ascending dose of 30mg WVE-003, an allele-selective stereopure antisense oligonucleotide (ASO)
Single ascending dose of 60mg WVE-003, an allele-selective stereopure antisense oligonucleotide (ASO)
Single ascending dose of 90mg WVE-003, an allele-selective stereopure antisense oligonucleotide (ASO)
Single dose of placebo
Three doses of 30mg WVE-003 Q8WK an allele-selective stereopure, antisense oligonucleotide (ASO)
Three doses of placebo Q8WK
