About

PRECISION-HD2 is a Phase 1b/2a multicenter, randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of single and multiple doses of WVE-120102 in adult patients with early manifest Huntington's disease (HD) who carry a targeted single nucleotide polymorphism (SNP) rs362331 (SNP2).

Enrollment: 88 patients

Sex: All

Ages: 25 to 65 years old

Volunteers: No Healthy Volunteers

Inclusion and exclusion criteria

Key Inclusion Criteria:

• Prescreened with targeted SNP on the same allele as the pathogenic CAG expansion
• Ambulatory, male or female patients aged ≥25 - ≤65 years
• Clinical diagnostic motor features of HD, defined as Unified Huntington's Disease Rating Scale (UHDRS) Diagnostic Confidence Score = 4
• Early manifest HD, Stage I or Stage II based on UHDRS Total Functional Capacity Scores ≥7 and ≤13

Key Exclusion Criteria:

• Malignancy or received treatment for malignancy, other than treated basal cell or squamous cell carcinoma of the skin, within the previous 5 years
• Received investigational drug or implantable device in prior 3 months or investigational oligonucleotide in prior 6 months or 5 halflives of the oligonucleotide, whichever is longer
• Clinically significant medical condition, unstable psychiatric symptoms, substance abuse, or pregnancy
• Inability to undergo brain MRI
• Bone, spine, bleeding, or other disorder that exposes the patient to risk of injury or unsuccessful lumbar puncture
