E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the dose dependent efficacy of oral CC-99677, administered every day (QD) compared to placebo, as determined by the attainment of the Assessment in SpondyloArthritis International Society Response Criteria (ASAS 20) after 12 weeks of treatment, in subjects with radiologically confirmed AS and inadequate response to nonsteroidal anti-inflammatory drugs (NSAIDs). |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the effects of oral CC-99677, administered QD, compared to placebo, after 12 weeks of treatment in subjects with AS, on: - The signs and symptoms of AS, as assessed by attainment of Assessment in SpondyloArthritis International Society 40% Response Criteria (ASAS 40), a composite measure of clinical improvement in axial spondyloarthritis, Ankylosing Spondylitis Disease Activity Score (ASDAS) with C-reactive protein (CRP) as the acute-phase reactant (ASDAS-CRP), and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) - Measures of physical function, as assessed by Bath Ankylosing Spondylitis Functional Index (BASFI) - Spinal and sacroiliac joint inflammation as measured by Spondyloarthritis Research Consortium of Canada (SPARCC) magnetic resonance imaging (MRI) score of sacroiliac joints and spine -Percent change from baseline in high-sensitivity C-reactive protein (hsCRP) - Safety and tolerability |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Biologic-Failure Substudy - Study objectives are the same for the biologic-naïve main study and for the biologic-failure substudy. Subjects with AS who have failed no more than 1 biologic agent taken for AS due to inadequate response to an approved dose for at least 12 weeks and/or unacceptable safety/tolerability of a biologic agent (in the opinion of the Investigator) will be recruited into this separate substudy, conducted concurrently with the biologic-naïve main substudy.
Pharmacogenomics substudy optional Pharmacogenetic testing will be conducted using DNA isolated from a single blood sample at baseline. DNA polymorphisms will be investigated for their ability to stratify patient subsets or response to CC-99677. Genetic markers to be assessed include, but are not limited to, those involved in MK2 signaling, CC-99677 metabolism, and those shown to be associated with ankylosing spondylitis.
|
|
E.3 | Principal inclusion criteria |
- Diagnosis of AS fulfilling the modified New York criteria - Active axial disease defined by a BASDAI score ≥ 4 and Total Back Pain ≥ 4 - Failed prior treatment with at least 2 NSAIDs for at least 4 weeks each - Subject has never received a biologic therapy for the treatment of AS, or have taken more than one biologic therapy - Concomitant use of sulfasalazine is permitted provided it is used at a stable dose for at least 4 weeks prior to Baseline (Day 1 of study)
|
|
E.4 | Principal exclusion criteria |
-Total ankylosis of the spine -Clinically significant back pain caused by diseases other than AS -Concurrent treatment or treatment within the 6 months prior to Baseline with JAK inhibitors, cell depleting biologic agents -Participation in any study of an investigational drug, including those for COVID-19 -History of malignancy -Oral corticosteroids > 10 mg/day for ≥ 2 weeks prior to Baseline Visit

E.5 End points |
E.5.1 | Primary end point(s) |
ASAS 20: Proportion of subjects who achieve an improvement in disease activity from baseline of ≥ 20% and ≥ 1 unit in at least 3 of the 4 ASAS domains on a scale of 0 to 10, and no worsening from baseline of ≥ 20% and ≥ 1 unit in the remaining domain on a scale of 0 to 10
