简要总结
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).

结局指标
主要结局
Safety: Number of Patients With Serious TEAEs
时间窗: Time Frame: Day 1 to end of study (up to Day 182 [32 mg cohort]/ Day 210 [all other cohorts])
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.
Safety: Number of Patients With Treatment-emergent Adverse Events (TEAEs)
时间窗: Day 1 to end of study (up to Day 182 [32 mg cohort]/ Day 210 [all other cohorts])
All TEAEs reported or observed during the study, including TEAEs resulting from concurrent illnesses, reactions to concurrent medications, or progression of disease states
Safety: Number of Patients Who Experienced Severe TEAEs
时间窗: Time Frame: Day 1 to end of study (up to Day 182 [32 mg cohort]/ Day 210 [all other cohorts])
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
Safety and Tolerability: Number of Patients Who Withdraw Due to TEAEs
时间窗: Time Frame: Day 1 to end of study (up to Day 182 [32 mg cohort]/ Day 210 [all other cohorts])
次要结局
- PK: Time of Occurrence of Cmax (Tmax)(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.)
- Clinical Effects: Total Functional Capacity (TFC)(Day 1 Day 1 to last observation - up to Day 140 (32 mg cohort) or Day 196 (all other cohorts))
- Pharmacokinetics (PK): Maximum Observed Concentration (Cmax)(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: Area Under the Plasma Concentration-time Curve (AUC 0-t)(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: Terminal Elimination Half-life(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.)
- Pharmacodynamics (PD): Percentage Change From Baseline in Mutant Huntingtin Protein(Day 1 to last observation - up to Day 140 (32 mg cohort) or Day 196 (all other cohorts))
