TOPLINE:
Pooled data from 9225 adults with psoriasis (PsO), psoriatic arthritis (PsA), and axial spondyloarthritis (axSpA) showed no new safety signals with extended exposure to ixekizumab (Taltz).
METHODOLOGY:
- Researchers combined patient data from 25 randomized, controlled trials of the safety and effectiveness of at least one dose of ixekizumab in adults with PsO (n = 6892), PsA (n = 1401), and axSpA (n = 932).
- The study population included patients with a mean age of approximately 43-49 years; at least 49% were male and at least 74% were White across the three conditions.
- Patients’ median duration of ixekizumab exposure was 1.3 years for PsO, 1.4 years for PsA, and 2.7 years for axSpA, with data up to 6 years for PsO and up to 3 years for PsA and axSpA.
- The primary outcomes were exposure-adjusted incidence rates per 100 patient-years overall and at successive year intervals for treatment-emergent adverse events, serious adverse events, and selected adverse events of interest.
TAKEAWAY:
- The incidence rate per 100 person-years for any treatment-emergent adverse event was 32.5 for PsO, 50.3 for PsA, and 38.0 for axSpA; these did not increase with lengthier exposure.
- The incidence rates for serious adverse events for patients with PsO, PsA, or axSpA were 5.4, 6.0, and 4.8 per 100 person-years, respectively.
- A total of 45 deaths were reported across the studies, including 36 in patients with PsO, six with PsA, and three with axSpA.
- Infections were the most common treatment-emergent adverse events across all patient groups, reported in patients at rates of 62.5% with PsO, 52.4% with PsA, and 57.9% with axSpA; incidence of infections did not increase over time.
IN PRACTICE:
“These final, end-of-study program results surrounding the long-term use of [ixekizumab] in patients with PsO, PsA, and axSpA should serve as an important point of reference for physicians considering [ixekizumab],” the researchers wrote.
SOURCE:
The lead author on the study was Atul Deodhar, MD, of Oregon Health & Science University, Portland. The study was published online on February 12 in Arthritis Research & Therapy.
LIMITATIONS:
Study limitations included the small sample sizes and short treatment durations in some studies, the primarily White study population, the inability to stratify risk, the lack of a long-term comparator, and potential survivor bias.
DISCLOSURES:
The studies in the review were supported by Eli Lilly. Lead author Dr. Deodhar disclosed an honorarium and serving on advisory boards at AbbVie, Bristol-Myers Squibb, Eli Lilly, Janssen, Novartis, Pfizer, and UCB, as well as research grants from AbbVie, Bristol-Myers Squibb, Celgene, Eli Lilly, Janssen, MoonLake, Novartis, Pfizer, and UCB.
