A Study of SPY072 in Rheumatic Disease (SKYWAY-RD)

June 3, 2026 updated by: Spyre Therapeutics, Inc.

Phase 2 Study to Assess the Efficacy and Safety of SPY002-072 in Adults With Moderately to Severely Active Rheumatologic Disease

This is a multi-center, double-blind, placebo-controlled, Phase 2, proof-of-concept basket study with the goal of assessing the efficacy and safety of SPY072 compared to placebo in adults (aged ≥18 years) with rheumatic disease (RD).

Study Overview

Detailed Description

The basket study comprises of substudies in rheumatoid arthritis (RA), axial spondyloarthritis (axSpA) and psoriatric arthritis (PsA) as follows:

  • RA substudy: Moderately to severely active RA despite treatment with conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs), biologic disease modifying anti-rheumatic drugs (bDMARDs), or targeted synthetic disease-modifying anti-rheumatic drugs (tsDMARDs)
  • axSpA substudy: Moderately to severely active axSpA despite treatment with non-steroidal anti-inflammatory drugs (NSAIDS), bDMARDs, or tsDMARDs
  • PsA substudy: Moderately to severely active PsA despite treatment with NSAIDs, csDMARDs, bDMARDs, or tsDMARDs

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Rheumatoid Arthritis: Change from baseline in Disease Activity Score in 28 joints (c-reactive protein) (DAS-CRP)
Time Frame: Week 12
The score is calculated based on the number of tender and swollen joints out of 28 assessed (TJC28 and SJC28), a measure of inflammation in the blood (c-reactive protein, CRP), and the subject's overall assessment of their health (patient global assessment). Scores range from 0-10. Higher scores indicate greater disease activity.
Week 12
Axial Spondyloarthritis: Change from baseline in Ankylosing Spondylitis Disease Activity Score (ADAS)
Time Frame: Week 16
The score combines 5 disease activity variables (back pain, duration of morning stiffness, patient global assessment of disease activity, peripheral pain/swelling and measure of inflammation) to measure disease activity. Lowest score is 0.6 and increases as disease worsens. Higher scores indicate greater disease activity.
Week 16
Psoriatic Arthritis: Proportion of participants who achieve an American College of Rheumatology 20 Response Criteria (ACR20) response
Time Frame: Week 16
The proportion of subjects who achieve at least 20% improvement in tender and swollen joint counts (TJC and SJC), and at least 20% improvement in 3 out of 5 other disease activity measures (patient global assessment, physician global assessment, patient pain assessment, health assessment questionnaire, and measure of inflammation) will be assessed.
Week 16

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Axial Spondyloarthritis: Proportion of participants who achieve an Assessment of Spondyloarthritis International Society (40% improvement) (ASAS40) response
Time Frame: Week 16
The proportion of subjects who achieve at least 40% improvement in at least 3 out of 4 key domains related to disease severity (patient global assessment of disease activity, back pain, physical function, inflammation) while not experiencing worsening in the remain domain will be assessed.
Week 16
Psoriatic Arthritis: Change from baseline in Disease Activity Index for Psoriatic Arthritis (DAPSA)
Time Frame: Week 16
The sum of 5 key disease variables (tender joint count, swollen joint count, patient pain assessment, patient global assessment of disease activity, and C-reactive protein) will be assessed. Scores range from 0.1 to 86. Higher score indicates higher disease activity.
Week 16
Rheumatoid Arthritis: Proportion of participants who achieve an ACR20 response
Time Frame: Week 12
The proportion of subjects who achieve at least 20% improvement in tender and swollen joint counts, and at least 20% improvement in 3 out of 5 other disease activity measures will be assessed.
Week 12
