Brief Summary:
The purpose of this study is to determine the efficacy and safety of ALLN-177 in patients with enteric hyperoxaluria.

Condition or disease Intervention/treatment Phase
Enteric Hyperoxaluria Drug: ALLN-177 Drug: Placebo Phase 3

Detailed Description:
This is a phase 3, multicenter, randomized, double-blind, placebo-controlled study. This study is designed to determine whether treatment with ALLN-177 for 28 days can reduce urinary oxalate excretion in patients with enteric hyperoxaluria and to evaluate the safety of ALLN-177 in this patient population compared to placebo.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Percent change from baseline in 24-hour urinary oxalate excretion during Weeks 1-4 [ Time Frame: 4 weeks ]
    Efficacy will be assessed based on percent change from baseline to the mean of Weeks 1-4, derived from all 24-hour collections during Weeks 1-4 on treatment


Secondary Outcome Measures :
  1. Proportion of subjects with a ≥ 20% reduction from Baseline in 24-hour urinary oxalate excretion during Weeks 1-4 [ Time Frame: 4 weeks ]
    Efficacy will be assessed based on proportion of subjects with ≥ 20% reduction from baseline to the mean of Weeks 1-4, derived from all 24-hour collections during Weeks 1-4 on treatment
