Taltz® (ixekizumab): Comorbidities in Phase 3 Ankylosing Spondylitis/Radiographic Axial Spondyloarthritis Trials

Comorbidities, reported as preexisting conditions, in at least 5% of patients from ixekizumab ankylosing spondylitis/radiographic axial spondyloarthritis clinical trials are provided.

Comorbid Conditions in COAST-V and COAST-W Ankylosing Spondylitis/Radiographic Axial Spondyloarthritis Clinical Trials

Around half of patients with AS/r-axSpA have comorbid conditions. A cross-sectional study found that the most common comorbid conditions, occurring in approximately 10% or more of AS patients, are coronary heart disease, anxiety, cancer, and hypertension. Compared with patients with nr-axSpA, patients with AS are more likely to also have psoriasis.1

In ixekizumab clinical trials, patient comorbidities were required to be controlled so as not to pose an unacceptable risk to a patient if participating in the study. Patients were excluded if they had the presence of significant uncontrolled disorders at screening that, in the opinion of the investigator, posed an unacceptable risk. Patients with current or a history of lymphoproliferative or malignant disease within 5 years of randomization and patients with a serious infection within 12 weeks prior to randomization were also excluded.2,3

Within the ixekizumab AS/r-axSpA phase 3 clinical development program, comorbidities (reported as preexisting conditions) that were reported in at least 5% of patients at baseline from COAST-V and COAST-W are listed in Table 1.

The phase 3 clinical trials were not designed to detect differences in the efficacy and safety of ixekizumab for the treatment of active AS in patients with or without specific comorbidities.4

Note: Drug hypersensitivity, while not generally considered to be a comorbidity, was reported as a preexisting condition in 5.9% of patients from COAST-V and in 4.4% of patients from COAST-W at baseline.

a Reported as preexisting conditions at baseline of the clinical trials.
