A Dose Escalation Study of IG3018 to Evaluate the Safety, Tolerability, Efficacy and Pharmacokinetics in Subjects With Hyperuricemia With or Without Chronic Kidney Disease

This is a phase I/II clinical study to evaluate the safety, tolerability, PK, and efficacy of IG3018 tablet in hyperuricemia (HUA) subjects with or without CKD.

Inclusion: For Part 1 and Part 2:; Subjects must meet all the following criteria to be included in the study:; Male or female, aged 18 to 75 years (both inclusive); According to the investigator's judgment, eGFR must be met as:; Part 1 only: subjects without CKD and have eGFR ≥ 60 mL/minute/1.73 m2 at screening phase; Part 2 only: subjects with advanced predialysis CKD (Stage 3a, 3b and Stage 4) have eGFR≥15 and <60 mL/minute/1.73 m2 at screening phase; The serum uric acid level for subjects need to meet any of the following:; For subjects already on ULT within 2 weeks prior to the screening visit, the serum uric acid would be measured during the screening visit/phase, and then at the end of the run-in phase, prior to confirming their eligibility. Subjects with ULT within 2 weeks before screening has fasting serum uric acid ≥ 0.48 mmol/L at the end of run-in phase; For subjects without ULT in 2 weeks prior to screening visit，the serum uric acid should be measured twice on 2 different days (at least 24 hours apart) prior to confirming their eligibility. Subjects without ULT within 2 weeks before screening has fasting serum uric acid ≥ 0.48 mmol/L at screening phase; Body Mass Index (BMI) ≥ 18 and ≤ 35 kg/m2 (both inclusive) at screening; Female subjects of child-bearing potential [defined as women who have experienced menarche but have not reached postmenopausal status (defined as at least 12 consecutive months of amenorrhea without any other identifiable cause other than menopause), and who have not undergone surgery (i.e., bilateral oophorectomy and/or bilateral salpingectomy and/or hysterectomy) or have no other cause of permanent infertility as determined by the investigator (e.g., Müllerian agenesis).] must agree to use highly effective contraceptive methods and must abstain from egg collection or donation from the screening phase to 90 days after the last dose of the IMP. And the male partner of a female subject also needs to agree to use highly effective method of birth control during this phase; Male subjects considered fertile must agree to not donate sperm, and take effective contraceptive methods from the screening phase to 90 days after the last dose of the IMP. And the female partner of male subjects also needs to agree to use a highly effective method of female contraception during this phase; Able to understand and give signed written informed consent form (ICF) and willing to comply with all study procedures; Only for Part 2; For subjects with anemia who require iron supplementation, steady iron or iron-containing drugs should be used for at least 3 months, and the original treatment regimen should be maintained during the study period.
