Study of DCR-PHXC-101 in Normal Healthy Volunteers and Patients With Primary Hyperoxaluria

This is a double-blind, placebo-controlled, dose escalation trial of DCR-PHXC in Healthy Volunteers (HVs) and patients with Primary Hyperoxaluria (PH). Once safety has been established in HV, PH patients with a confirmed diagnosis of PH1 and PH2 will be enrolled across multiple dosing cohorts. The study design will allow enrollment of PH patient cohorts at a given dose level once safety has been demonstrated in HV at that dose level. The study will be conducted in two parts: Part A: Single ascending dose (SAD) in HV; Part B: SAD in patients with PH1 and PH2 (lagging Part A by 1 dose level cohort).

Study Type: Interventional (Clinical Trial)
Actual Enrollment: 43 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: Two-arm (active and placebo), single-blind, SAD period (Group A, HVs) followed by open-label, SAD period (Group B, PH1 and PH2 patients).
Masking: Double (Participant, Investigator)
Masking Description: SAD period in HV is single-blind (unblinded clinical site staff member who is not a member of study team administers dose). SAD period in Group B (PH1 and PH2 patients) is open-label.
Primary Purpose: Treatment
Official Title: A Placebo-Controlled, Single-Blind, Single-Center Phase 1 Study in Normal Healthy Volunteers and Open-Label Multi-Center Study in Patients With Primary Hyperoxaluria to Evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Single Ascending Doses of DCR-PHXC Solution for Injection (Subcutaneous Use)
