Clinical Trial Summary

This is an open-label, single-dose study to evaluate the pharmacokinetics and safety of DBPR108 in subjects with mild, moderate, severe renal impairment and subjects with kidney failure compared to the matched control subjects with normal renal function.

Description:

This is an open-label, single-dose Phase I study that evaluate the pharmacokinetics, safety, and tolerability of a single dose of DBPR108 100 mg in subjects with mild, moderate, and severe renal impairment (RI), subjects with kidney failure and the control subjects with normal renal function. This study consists of a screening period (Day -14 to Day -1), a baseline period (Day -1), a treatment period (Day 1 to Day 3), and a follow-up call on Day 6.

Subjects will be enrolled in the following groups:

Estimated glomerular filtration rate (eGFR) will be calculated based on Modification of Diet in Renal Disease (MDRD) equation at screening.

(A) mild renal impairment (60 ≤ eGFR≤ 89 mL/min/1.73m2); (B) moderate renal impairment (30 ≤ eGFR≤ 59 mL/min/1.73m2); (C) severe renal impairment (15 ≤ eGFR≤ 29 mL/min/1.73m2); (D) kidney failure (<15 mL/min/1.73m2, not on hemodialysis); (E) control subjects with normal renal function will be matched with subjects with HI by weight, age, and sex (eGFR≥90 mL/min/1.73m2).

Approximately 8 subjects will be enrolled in each group.

Subjects with RI only:

• Subjects with medically stable RI corresponding to the Classifications of Renal Function based on eGFR: mild RI: 60 to 89 ml/min/1.73m2; moderate RI: 30 to 59 ml/min/1.73m2, severe RI:15-29 ml/min/1.73m2, kidney failure:<15 ml/min/1.73m2 (not on hemodialysis);

• Not in use of any prescription drug, over-the-counter drug, or herbal medicine within 2 weeks prior to screening, except for the medication necessary for RI/ other comorbidities with no effect on the study drug absorption, distribution, metabolism, or excretion (last more than four weeks in good compliance);

• Based on physical examination, vital sign measurements, 12-lead electrocardiogram (ECG), and clinical laboratory tests (serum potassium: 3.5-5.5 mmol/L);

Subjects with normal renal function only:

• Weight, age, and sex must be matched with subjects with HI;

• eGFR=90 ml/min/1.73m2;

• Not in use of any prescription drug, over-the-counter drug, or herbal medicine within 2 weeks prior to screening, except for the medication necessary for underlying conditions other than renal disease with no effect on the study drug absorption, distribution, metabolism, or excretion (last more than four weeks in good compliance).

Exclusion Criteria:

All subjects:

• Consumption of grapefruit juice, methylxanthine-rich food or beverage (such as coffee, tea, cola, chocolate, energy drinks) within 48 hours before the administration, or have strenuous exercise, or have other factors affecting drug absorption, distribution, metabolism, excretion, etc.;

• Participation in another clinical trial within 3 months before screening;

• Blood donation (or blood loss) =400 mL, or receiving whole blood transfusions or erythrocyte suspension transfusions within 3 months prior to the screening;

• Have acute hepatitis or a chronic liver disease; aspartate aminotransferase (AST), alanine aminotransferase (ALT) or bilirubin > 2 × upper limit of normal;
