Evaluation of TRC101 in Subjects With Metabolic Acidosis Associated With Chronic Kidney Disease

April 23, 2021 updated by: Tricida, Inc.

A Phase 3, Multicenter, Double-Blind, Randomized, Placebo-Controlled Study to Evaluate the Efficacy and Safety of TRC101 in Subjects With Chronic Kidney Disease and Metabolic Acidosis

This is a multicenter, double-blind, placebo-controlled, parallel-design study. The study will enroll approximately 210 adult male and female subjects with stage 3 or 4 chronic kidney disease and metabolic acidosis. The study dosing (TRC101 or placebo) will continue for 12 weeks once daily.

The maximum study duration is anticipated to be up to 16 weeks.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 81 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Key Inclusion Criteria:

  • Blood bicarbonate level of 12 to 20 mEq/L.
  • Estimated glomerular filtration rate (eGFR) of 20 to 40 mL/min/1.73m2.
  • Stable kidney function defined as <=20% variability in eGFR during screening period.

Key Exclusion Criteria:

  • Any level of low blood bicarbonate during the screening period that in the opinion of the Investigator, requires emergency intervention or evaluation for an acute acidotic process.
  • Anuria, dialysis, acute kidney injury, or history of acute kidney insufficiency within 3 months prior to screening.
  • Heart failure with maximum New York Heart Association (NYHA) Class IV symptoms or that required hospitalization during the preceding 6 months.
  • Heart or kidney transplant.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Subjects With Change From Baseline in Serum Bicarbonate of ≥ 4 mEq/L or Serum Bicarbonate Within the Normal Range
Time Frame: Baseline to Week 12
Composite endpoint of the percentage of subjects having a change from baseline in serum bicarbonate ≥ 4 mEq/L or having serum bicarbonate in the normal range (22 - 29 mEq/L) at the end of treatment (Week 12 Visit).
Baseline to Week 12

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline to End of Treatment in Serum Bicarbonate
Time Frame: Baseline to Week 12
Mean change from baseline to end of treatment (Week 12 Visit) in serum bicarbonate
Baseline to Week 12

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
September 26, 2017

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
May 4, 2018

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
