NCT03390842

Brief Summary

This study is a 40-week, blinded, placebo-controlled extension of Study TRCA-301 (NCT03317444). Eligible subjects who complete the 12-week treatment period in Study TRCA-301 have the option to participate in this extension study evaluating the long-term safety and durability of effect of TRC101 in subjects with non-dialysis dependent chronic kidney disease and metabolic acidosis. Eligible subjects will be treated with TRC101 or placebo once daily (QD) on an out-patient basis for the subsequent 40 weeks. Subjects will continue to receive the same blinded treatment (TRC101 or placebo) that they received in Study TRCA-301.

Outcome Measures

Primary Outcomes (1)

  • Incidence of Adverse Events, Serious Adverse Events, and Adverse Events Leading to Withdrawal.

    The incidence of adverse events (AEs), serious adverse events (SAEs) and AEs leading to withdrawal. For incidence of AEs and SAEs, see Adverse Events Section. For incidence of AEs leading to withdrawal, see endpoint values below.

    Week 12 Visit in the parent study, TRCA-301, to the Week 54 Visit in the extension study, TRCA-301E.

Secondary Outcomes (4)

  • Subjects With Change From Baseline in Serum Bicarbonate of ≥ 4 mEq/L or Serum Bicarbonate Within the Normal Range

    Baseline in the parent study, TRCA-301, to the Week 52 Visit in the extension study, TRCA-301E.

  • Change From Baseline in Serum Bicarbonate at the End of Treatment

    Baseline in the parent study, TRCA-301, to the Week 52 Visit in the extension study, TRCA-301E.

  • Change From Baseline in the Total Score of the KDQOL-PFD at the End of Treatment

    Baseline in the parent study, TRCA-301, to the Week 52 Visit in the extension study, TRCA-301E.

  • Change From Baseline in the Duration of Repeated Chair Stand Test at the End of Treatment

    Baseline in the parent study, TRCA-301, to the Week 52 Visit in the extension study, TRCA-301E.

Eligibility Criteria

Age18 Years - 85 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Completed the 12-week treatment period and attended the Week 12 Visit in the parent study TRCA-301.
  • Blood bicarbonate level of \>= 12 mEq/L at the Week 12 Visit in the parent study TRCA-301.

You may not qualify if:

  • Any level of low blood bicarbonate at the Week 12 Visit that, in the opinion of the Investigator, requires emergency intervention or evaluation for an acute acidotic process.
  • Required dialysis for acute kidney injury or worsening CKD during the parent study TRCA-301.
  • Planned initiation of renal replacement therapy within 6 months following study entry.
  • History or current diagnosis of diabetic gastroparesis, bowel obstruction, swallowing disorders, severe gastrointestinal disorders, inflammatory bowel disease, major gastrointestinal surgery, or active gastric/duodenal ulcers.
  • Serum calcium \<= 8.0 mg/dL at the Week 10 in the parent study TRCA-301.
