Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this trial is to investigate the efficacy and safety of dapansutrile (OLT1177®) tablets in subjects with an acute gout flare.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a multi-center Phase 2/3 randomized, double-blind, placebo-controlled, parallel-group safety and efficacy study of dapansutrile (OLT1177®), a specific NLRP3 inhibitor, conducted in subjects with acute gout flare. Up to 300 eligible subjects will be randomized 2:1 to one of two treatment arms to receive either dapansutrile tablets or matching placebo twice daily for 7 days. An initial loading dose on Study Day 1 will be followed by a twice daily maintenance dosing regimen.

Subjects presenting with acute gout flare that began within 96 hours prior to the Baseline/Day 1 visit will be evaluated for eligibility. Subjects who are determined to be eligible will be randomized into either an active treatment arm (2/3 of the subjects enrolled) or the placebo arm (1/3 of the subjects enrolled).

Eligible subjects who are randomized into the study will also be provided with rescue medication at the Baseline/Day 1 Visit. No other pain medications, anti-inflammatory drugs (e.g., steroids or nonsteroidal anti-inflammatory drugs), or treatments for gout flare are allowed during the Treatment Period.

During the Treatment Period, subjects will return to the clinic trial site on Day 4 and, following the 7-day Treatment Period, subjects will return to the clinical trial site on Day 8, and then Day 15 with safety data collected through Day 36.

* Has ≥ 4 joints with an acute gout flare at Screening/Baseline
* Presence of active rheumatoid arthritis or other acute inflammatory arthritis
* Evidence/suspicion of infectious/septic arthritis
* Clinically significant general pain or non-gout-related joint pain that would interfere with the subject's ability to accurately assess pain in the target joint
* Known diagnosis of chronic kidney disease or known history of renal impairment
* Positive test for severe acute respiratory syndrome coronavirus 2 (SARS- CoV-2) infection, if tested, within 4 weeks of the Screening/Baseline
* Active malignancy or recent malignancy with any systemic anti-cancer treatment
* Has a hypersensitivity or allergy to OLT1177® or other drugs in its class
