Safety, Tolerability, Pharmacokinetics, and Preliminary Pharmacological Studies of SSS11 in Patients With Gout and Hyperuricemia After Multiple Administrations, Dose Escalation, Randomized Double-blind, Placebo-controlled Trials
This is a safety, tolerability, pharmacokinetics, and preliminary pharmacological study of multiple administration, dose escalation, randomized double-blind, placebo-controlled.The main purpose of this experiment is to evaluate the safety and tolerability of multiple injections of PEGylated recombinant Candida urate oxidase (test drug code: SSS11) in patients with gout and hyperuricemia.The experimental period includes a screening period of 4 weeks, a treatment period of 4 or 8 weeks, and an observation period of 4 weeks。
• A patient with clinical diagnosis of gout (according to the 2015 ACR/EULAR gout classification criteria), non acute attack phase, and hyperuricemia {under normal purine diet, blood uric acid\>420 µ mol/L (7 mg/dl) not tested twice on an empty stomach on the same day}。
• Screening period blood uric acid\>420 µ mol/L (7mg/dl)。
