Brief Summary

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

This is a randomized, parallel-arm, multicenter study to compare the safety and efficacy profiles of SEL-212 and KRYSTEXXA®. Participants will be randomized 1:1 to receive treatment with SEL-212 or KRYSTEXXA® for 6 months. Efficacy assessments, as measured by serum uric acid (SUA) levels, will be conducted at intervals that are appropriate to determine treatment effect differences. Safety will be monitored throughout the study.

Detailed Description

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

This is a randomized, parallel-arm, multicenter study to compare the safety and efficacy profiles of SEL-212 and KRYSTEXXA®. Participants will be randomized 1:1 to receive treatment with SEL-212 \[a combination of pegadricase (SEL-037) and ImmTOR (SEL-110)\] or KRYSTEXXA® for 6 months.

Study participants in the SEL-212 arm will receive study drug every 28 days for a total of up to 6 infusions of SEL-212. Study participants in the KRYSTEXXA® arm will receive study drug according to the manufacturer's prescribing information, i.e., every 14 days for a total of up to 12 infusions of KRYSTEXXA®.

Efficacy assessments, as measured by SUA levels, will be conducted at intervals that are appropriate to determine treatment effect differences. Safety will be monitored throughout the study.
