A Study of SEL-212 in Patients With Gout Refractory to Conventional Therapy II — DISSOLVE II  

Chronic Gout Clinical Trial

Official title: A Randomized Double-Blind, Placebo-Controlled Study of SEL-212 in Patients With Gout Refractory to Conventional Therapy

Status Completed

Clinical Trial Summary

This is one of two replicate randomized, double-blind, placebo-controlled, parallel arm trials to determine the safety and efficacy of two different dose levels of SEL-212 compared to placebo. 112 and 153 patients, stratified as to the presence or absence of tophi, were randomized in a 1:1:1 allocation ratio prior to Baseline to receive treatment with one of two dose levels of SEL-212 or placebo every 28 days for approximately 6 months in each trial respectively (SEL-212/301 and SEL-212/302). Analysis of primary and key efficacy were performed at Day 28 of Treatment Period 6. Safety was monitored throughout the study.

Clinical Trial Description

This is one of two replicate randomized, double-blind, placebo-controlled, parallel arm trials to determine the safety and efficacy of two different dose levels of SEL-212 compared to placebo. 112 and 153 patients, stratified as to the presence or absence of tophi, were randomized in a 1:1:1 allocation ratio prior to Baseline to receive treatment with one of two dose levels of SEL-212 or placebo every 28 days for approximately 6 months in each trial respectively (SEL-212/301 and SEL-212/302). The SEL-212 doses differed as to the SEL-110.36 component. Participants received SEL-037 administered at a dose of 0.2 mg/kg via intravenous (IV) infusion immediately after receiving SEL-110.36 at a dose of either 0.1 mg/kg (SEL-212 low-dose) or 0.15 mg/kg (SEL-212 high-dose) via IV infusion. The placebo consisted of normal saline. Placebo subjects who completed the study will be offered enrollment in an open-label extension study for treatment with SEL-212 (SEL-212/303). Efficacy assessments were conducted at intervals that are appropriate to determine treatment effect with samples for the primary endpoint drawn during Treatment Period 6. Safety was monitored throughout the study with an independent data safety monitoring board (DSMB). ;
