A Study of IN026 in Participants With Refractory Gout

Recruiting now · Phase 1

Conditions studied: Refractory Gout

In brief

The goal of this clinical study is to learn if IN026 Injection is safe and works to lower uric acid levels in adults with refractory gout (gout that does not respond well to standard treatments). The main questions it aims to answer are: * What medical problems do participants have when taking IN026, such as changes in vital signs, blood tests, or heart rhythm? * How does the body absorb, process, and respond to IN026, and does it trigger an immune reaction? * Does IN026 lower uric acid levels in the blood and reduce tophi? Investigator will start with lower doses of IN026 and slowly increase the dose to find the well-tolerated dose. Participants will: * Receive IN026 through an intravenous (IV) drip into a vein at a set dose. * Complete a screening period of up to 4 weeks, followed by treatment and check-ups for up to 20 weeks. * Have blood and urine samples taken at set times to check safety and how the body responds to IN026.
