Study summary

The purpose of this study is to determine the efficacy, durability and long-term safety of reloxaliase in patients with enteric hyperoxaluria.

Read the detailed description

This is a phase 3, global, multi-center, randomized, double-blind, placebo-controlled study. This study is designed to determine the short- and long-term efficacy of reloxaliase in terms of reducing urinary oxalate excretion and clinical benefits compared to placebo.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Provided
  2. Age 18 years or older
  3. Has an underlying enteric disorder associated with malabsorption with known or suspected history of hyperoxaluria (e.g., history of kidney stones or oxalate nephropathy)
  4. Urinary oxalate ≥ 50 mg/24 hr
  5. Has at least 1 documented kidney stone within 2 years

Exclusion criteria

Exclusion Criteria:

  1. Acute renal failure or estimated (eGFR) \< 30 mL/minute/1.73 m2
  2. Has a known genetic, congenital, or other cause of kidney stones
  3. Unable or unwilling to discontinue Vitamin C supplementation >200mg daily
  4. Cannot establish baseline kidney stone burden
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Study arms

  • Experimental
    Reloxaliase

    Reloxaliase (ALLN-177) 142 mg of oxalate decarboxylase (equivalent to 3,750 units of enzyme activity) per capsule

    Drug: Reloxaliase

  • Placebo comparator
    placebo

    placebo capsule

    Drug: Placebo

Interventions

  • Reloxaliase 2 capsules, orally, with each meal/snack, 3 to 5 times per day

    Also known as: Placebo capsule

What researchers measure

Primary outcomes

  1. Percent change from baseline in 24-hour urinary oxalate excretion during Weeks 1 to 4

    Efficacy will be assessed based on percent change from baseline to the average across Weeks 1 to 4, derived from all 24-hour collections during Weeks 1 to 4 on treatment

    Time frame: 4 weeks

  2. Proportion of subjects with kidney stone disease progression (composite of symptomatic kidney stone(s) or finding of new or enlarged kidney stone(s) on imaging)

    Efficacy will be assessed by comparing kidney stone disease progression event rate on reloxaliase vs. placebo

    Time frame: up to 48 months

Secondary outcomes

  1. Percent change from baseline in 24-hour urinary oxalate excretion during Weeks 16-24

    Efficacy will be assessed based on percent change from baseline to the average across Weeks 16-24, derived from all 24-hour collections during Weeks 16-24 on treatment

    Time frame: 24 weeks

  2. Proportion of subjects with a ≥ 20% reduction from baseline in 24-hour urinary oxalate excretion during Weeks 1-4

    Efficacy will be assessed based on proportion of subjects with ≥ 20% reduction from baseline to the average across Weeks 1-4, derived from all 24-hour collections during Weeks 1-4 on treatment

    Time frame: 4 weeks

  3. Hospitalizations or emergency room (ER) visits or procedures for the management of kidney stones

    Efficacy will be assessed by comparing utilization on reloxaliase vs. placebo

    Time frame: up to 48 months

  4. Change in estimated glomerular filtration rate (eGFR) from baseline

    Efficacy will be assessed by comparing the rate of change in eGFR on reloxaliase vs. placebo

    Time frame: up to 48 months
