To evaluate the safety, tolerability, pharmacokinetics and pharmacodynamic characteristics, and initial efficacy of single and multiple dosing of peguricase for injection with methotrexate in patients with gout who remain uncontrolled after standardized treatment with conventional uric acid-lowering drugs.
This study is a phase Ib single and multiple dosing, dose-increasing. Three dose groups of 4, 8 or 12 mg were planned, then exploring the most appropriate dose for phase II clinical trials, and to provide basis for formulation of administration regimen for phase II clinical trials.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
SIBP-R002Drug
Also called Peguricase for injection
Injection; strength: 4mg. Each group consists of 12 participants. Firstly, 4 sentinel participants were enrolled in the single dose phase of peruricase for injection and methotrexate. After the sentinel participants completed a 5-day safety observation of the single dose, the remaining 8 participants in this group can be enrolled simultaneously. If there are no special circumstances, the participants in this group will enter the multi-dose stage of peruricase for injection combined with methotrexate within 2-4 weeks after completing a single dose.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing SIBP-R002 and Methotrexate in people with Gout, run by Shanghai Institute Of Biological Products at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 26 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 8 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Dandan Chen, Master (86-021-62800991, ddchen.sh@sinopharm.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
AE(Adverse Events) (time frame: 14 weeks after the first dose). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Jan 2026.
