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

Outcomes

Primary Outcomes

Safety: Number of Patients With Treatment-emergent Adverse Events (TEAEs)

All TEAEs reported or observed during the study, including TEAEs resulting from concurrent illnesses, reactions to concurrent medications, or progression of disease states

Time frame: Day 1 to end of study (up to Day 182 [32 mg cohort]/ Day 210 [all other cohorts])

Safety: Number of Patients Who Experienced Severe TEAEs

Number of patients who experienced a severe treatment-emergent adverse event. Severity was evaluated using the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0

Time frame: Time Frame: Day 1 to end of study (up to Day 182 [32 mg cohort]/ Day 210 [all other cohorts])

Safety: Number of Patients With Serious TEAEs

A serious TEAE is defined as any event that results in death, is immediately life threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, or is a congenital anomaly/birth defect not present at Prescreening.

Time frame: Time Frame: Day 1 to end of study (up to Day 182 [32 mg cohort]/ Day 210 [all other cohorts])

Safety and Tolerability: Number of Patients Who Withdraw Due to TEAEs

Time frame: Time Frame: Day 1 to end of study (up to Day 182 [32 mg cohort]/ Day 210 [all other cohorts])

Secondary Outcomes

Pharmacokinetics (PK): Maximum Observed Concentration (Cmax)

Cmax of WVE-120102 in plasma

Time frame: Patients participating in Period 1 (SAD) had PK samples collected on Day 1 predose through 24-48 hours postdose. Patients participating in Period 2 (MAD) had PK samples collected predose on Day 112 and through 4 hours postdose.

PK: Time of Occurrence of Cmax (Tmax)
