This is a multicenter, prospective, randomized, controlled study that will enroll approximately 429 subjects. The screening period will last 4-8 weeks. Subjects will undergo pre-screening based on eGFR and urinary albumin-to-creatinine ratio (UACR). Only non-dialysis subjects meeting the following criteria confirmed by local laboratories within 6 months prior to screening will be eligible for central laboratory screening:
10 mL/min/1.73m² ≤ eGFR \< 30 mL/min/1.73m² and 150 mg/g (16.95 mg/mmol) ≤ UACR \< 5000 mg/g (565 mg/mmol).
Unless contraindicated due to intolerance, subjects with 20 mL/min/1.73m² ≤ eGFR \< 30 mL/min/1.73m² must receive stable, maximally tolerated labeled daily doses of ACEi or ARB for at least 4 weeks prior to randomization. For subjects with 10 mL/min/1.73m² ≤ eGFR \< 20 mL/min/1.73m², investigators will determine ACEi/ARB treatment based on patient condition per KDIGO guidelines. Other antihypertensive, lipid-lowering, and glucose-lowering therapies should be stabilized for approximately 4 weeks before randomization. Investigators are encouraged to maintain stability of medications known to affect serum creatinine levels during screening and approximately 2 weeks prior to any serum chemistry measurements throughout the study. Eligible subjects will be randomized in a 1:1:1 ratio to receive Henagliflozin (10 mg q.d., 5 mg q.d.) or conventional therapy.
Thereafter, subjects will undergo laboratory assessments, concomitant medication review, adverse event collection, and clinical endpoint ascertainment at Week 4 (Day 30), Week 12 (Day 90), and Week 24 (Day 180), followed by every 12-week intervals. Throughout the study, all subjects will receive glycemic, blood pressure (target SBP \<140 mmHg and DBP \<90 mmHg), and lipid management according to current guidelines. All subjects will complete an end-of-study visit. Subjects discontinuing study drug prematurely should continue all subsequent study visits.
10 mL/min/1.73m² ≤ eGFR < 30 mL/min/1.73m² (CKD-EPI equation), and
150 mg/g (16.95 mg/mmol) ≤ Urine Albumin-to-Creatinine Ratio (UACR) < 5000 mg/g (565 mg/mmol)
Age ≥ 18 years, male or femal
Participants with 20 mL/min/1.73m² ≤ eGFR < 30 mL/min/1.73m² must be on a stable and tolerated dose of an ACE inhibitor (ACEI) or ARB for at least 4 weeks, unless intolerant (reasons for intolerance must be documented). Participants with 10 mL/min/1.73m² ≤ eGFR < 20 mL/min/1.73m² should have ACEI/ARB use determined by the investigator based on the patient's clinical status and KDIGO guideline recommendations;
Received SGLT2 inhibitor treatment within 8 weeks prior to enrollment or with a history of SGLT2 inhibitor intolerance;
Receiving combined therapy with an ACE inhibitor (ACEi) and an ARB, or a renin inhibitor combined with ACEi or ARB (based on self-report at screening and randomization visits);
On maintenance dialysis, has a functioning kidney transplant, or is a planned living donor transplant recipient (based on self-report at screening and randomization visits);
Polycystic kidney disease, active lupus nephritis, or systemic vasculitis;(5) Symptomatic hypotension, or systolic blood pressure <90 mmHg or >180 mmHg at screening;
