Observational Study to Evaluate the Safety and Efficacy of Kremezin IDT/Fine Gran in Progressive Chronic Kidney Disease Patients.

November 4, 2026 updated by: HK inno.N Corporation

A Multi-center, Prospective, Observational Study to Evaluate the Safety and Efficacy of Kremezin IDT/Fine Gran in Progressive Chronic Kidney Disease Patients.

This study will be conducted under routine clinical practice in adults diagnosed with advanced chronic renal failure for whom treatment with Kremezin immediate-release tablets or Kremezin fine granules has been determined as part of standard clinical care. Kremezin will be prescribed and administered in accordance with the approved product labeling. Study data will be collected at up to three time points through Week 48: baseline, Week 24, and Week 48. Effectiveness will be assessed using serum creatinine (Scr), estimated glomerular filtration rate (eGFR), and the investigator's overall assessment; treatment satisfaction and safety information will also be collected.

Detailed Description

This is a multicenter, prospective, observational study to evaluate the effectiveness and safety of Kremezin immediate-release tablets or Kremezin fine granules in adults diagnosed with advanced chronic renal failure. During routine clinical visits, the investigator will determine whether Kremezin treatment is appropriate. The investigator will prescribe the selected formulation in accordance with the product labeling and routine clinical practice. The treatment decision must be made before the participant provides consent to participate in the study and without any study-related intervention.

Adults will receive Kremezin immediate-release tablets or fine granules at the approved dosage-2 g three times daily (4 tablets per dose or 1 sachet per dose, respectively)-for the treatment period determined in routine care, with study data collected through Week 48. Scr and eGFR will be recorded at baseline, Week 24 (±3 weeks), and Week 48 (±4 weeks). At Weeks 24 and 48, the investigator will also assess overall effectiveness and treatment satisfaction and collect safety information. Blood pressure and laboratory results will be collected when available. The study will not require additional treatment or visits beyond routine clinical care.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Proportion of participants with an effective overall assessment at Week 24
Time Frame: Baseline to Week 24 (Week 24 ±3 weeks)

Overall effectiveness will be assessed by the investigator based on serum creatinine (Scr) and estimated glomerular filtration rate (eGFR). Participants will be classified as effective, ineffective, or unevaluable; unevaluable participants will be excluded from the analysis.

Baseline to Week 24 (Week 24 ±3 weeks)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Proportion of participants with an effective overall assessment at Week 48
Time Frame: Baseline to Week 48 (Week 48 ±4 weeks)

Overall effectiveness will be assessed by the investigator based on Scr and eGFR. Participants will be classified as effective, ineffective, or unevaluable; unevaluable participants will be excluded from the analysis.

Baseline to Week 48 (Week 48 ±4 weeks)
Change from baseline in serum creatinine (Scr) at Weeks 24 and 48
Time Frame: Baseline to Week 24 and Week 48

Change = Scr at Week 24 or Week 48 - Scr at baseline.

Baseline to Week 24 and Week 48
Change from baseline in estimated glomerular filtration rate (eGFR) at Weeks 24 and 48
Time Frame: Baseline to Week 24 and Week 48

eGFR will be calculated using the CKD-EPI equation. Change = eGFR at Week 24 or Week 48 - eGFR at baseline.

Baseline to Week 24 and Week 48
Mean treatment satisfaction score at Weeks 24 and 48
Time Frame: Week 24 and Week 48

Treatment satisfaction will be assessed on a 7-point scale, from 1 (extremely dissatisfied) to 7 (extremely satisfied).

Week 24 and Week 48
