Guangdong Hengqin Novagains Biopharmaceutical Co., Ltd.69 enrolled

Overview

The primary objective of this study is to evaluate the safety, tolerability and pharmacokinetic (PK) profiles of ascending single orally administered doses of F-02-2-Na in adult subjects (to include the Mass Balance) \& multiple orally administered doses of F-02-2-Na in adult subjects with Hyperuricemia.

* Part 1: Approximately 39 subjects will be enrolled, 6 groups A1-A6 are predefined (A1 will enroll 3 subjects and A2\&A6 will enroll 6 subjects, A3A4A5 will enroll 8 subjects). The planned dose escalation of F-02-2-Na will include 6-ascending single-dose cohorts with tentative PO doses ranging from 0.5 mg to 200 mg. Subjects in each SAD cohort will be randomly assigned to receive active drug or matching placebo in a 2:1 or 3:1 ratio (n=2 or 4 or 6 subjects to receive F-02-2-Na, n=1 or 2 subjects will be administered placebo).Safety and PKPD assessments will continue for 72 hours post dose, with discharge from the Phase I Clinical Research Center following completion of all 72-hour procedures on Day 4. Subjects will receive a phone call for an End-of-Study (EOS) follow-up on Day 7 (±1 day).In SAD A3 (25 mg), collected blood, urine, and feces will be used for the mass balance study. * Part 2: Approximately 30 subjects will be enrolled.Three dose groups (B1\~B3) are predefined, with 10 subjects per group (including 2 subjects receiving placebo). The administration doses are 25 mg, 50 mg, and 100 mg respectively, administered once daily for 7 consecutive days (a total of 7 administrations).After subjects complete the collection of pharmacokinetic and pharmacokinetics blood \& urine samples at 72.0 hours post-administration and undergo relevant examinations, they may leave the Phase I Clinical Research Center upon completion of all tests .

Interventions

F-02-2-Na Tablet (0.5 mg)DRUG

The intervention involves the single oral administration of F-02-2-Na tablets at a dose of 0.5 mg, given once in a fasting state (after at least 10 hours of fasting). The drug is formulated as film-coated tablets with a strength of 1 mg per tablet, manufactured by Guangdong Hengqin Novagains Biopharmaceutical Co., Ltd. (batch number: 250901). Safety and PKPD parameters will be continuously monitored for 72 hours following administration.

F-02-2-Na Matching Placebo (0.5mg)DRUG

The intervention consists of the single oral administration of a matching placebo (0.5mg) for F-02-2-Na. Formulated as film-coated tablets (consistent with F-02-2-Na in appearance, color, and strength), the placebo contains no F-02-2-Na or other pharmacologically active ingredients and is manufactured by Guangdong Hengqin Novagains Biopharmaceutical Co., Ltd. (batch number: 250101). The administration conditions are identical to those of the experimental arm in this study; however, it has no therapeutic effect.

The absolute change is calculated as the difference between sUA levels at each predefined time point and the baseline sUA level (absolute change = sUA level at predefined time point - baseline sUA level).

Time frame: From pre-dose (baseline) to 72 hours after the last dose.

Percentage Change in Serum Uric Acid (sUA) Levels in Adult Subjects After Single and Multiple Oral Administrations of F-02-2-Na

To evaluate the percentage change in serum uric acid (sUA) levels in adult subjects after single and multiple oral administrations of F-02-2-Na. The percentage change is calculated relative to the baseline sUA level at each predefined time point (percentage change = \[(sUA level at predefined time point - baseline sUA level)/baseline sUA level\] × 100%).

Time frame: From pre-dose (baseline) to 72 hours after the last dose.

Uric Acid Excretion (AeUR) in Adult Subjects After Single and Multiple Oral Administrations of F-02-2-Na

To evaluate the uric acid excretion (AeUR) in adult subjects after single and multiple oral administrations of F-02-2-Na. AeUR is defined as the total amount of uric acid excreted in urine within a specified time period (e.g., 24 hours or predefined intervals after administration), reflecting the cumulative excretion capacity of uric acid.

Time frame: From pre-dose (baseline) to 72 hours after the last dose.

Uric Acid Clearance Rate (CLUR) in Adult Subjects After Single and Multiple Oral Administrations of F-02-2-Na

To evaluate the uric acid clearance rate (CLUR) in adult subjects after single and multiple oral administrations of F-02-2-Na. CLUR is calculated as the ratio of uric acid excretion rate to serum uric acid concentration (CLUR = AeUR / AUC\_sUA), reflecting the efficiency of renal uric acid clearance, with the unit of volume per unit time (e.g., mL/min).

Time frame: From pre-dose (baseline) to 72 hours after the last dose.

Area Under the Curve (AUC) of Serum Uric Acid (sUA) Dynamic Change Curve in Adult Subjects After Single and Multiple Oral Administrations of F-02-2-Na

To evaluate the area under the curve (AUC) of the serum uric acid (sUA) dynamic change curve in adult subjects after single and multiple oral administrations of F-02-2-Na. AUC is calculated by integrating the sUA concentration-time curve over a predefined time period (e.g., AUC₀-t, AUC₀-∞), reflecting the total exposure level of sUA during the observation period, with the unit of concentration × time (e.g., μmol·h/L).

Time frame: From pre-dose (baseline) to 72 hours after the last dose.

Total 24-Hour Uric Acid Excretion in Adult Subjects After Single and Multiple Oral Administrations of F-02-2-Na

To evaluate the total 24-hour uric acid excretion in adult subjects after single and multiple oral administrations of F-02-2-Na. It is determined by collecting 24-hour urine samples, measuring the uric acid concentration in the urine, and calculating the total amount of uric acid excreted in 24 hours (Total 24-hour uric acid excretion = Urine uric acid concentration × 24-hour urine volume), with the unit of mass (e.g., mg/24h or mmol/24h).

Time frame: From pre-dose (baseline) to 72 hours after the last dose.
