TOPLINE:
particularly in subacute and chronic cases.
METHODOLOGY:
- Researchers conducted a randomized phase 2 trial to evaluate the efficacy and safety of iberdomide in 288 patients with CLE (mean age, 45 years; 97% women). Iberdomide is a cereblon modulator, which results in degradation of two transcription factors of immune cell development and homeostasis — Ikaros and Aiolos — that have been implicated in the genetic predisposition of systemic lupus.
- CLE Disease Area and Severity Index Activity (CLASI-A) endpoints included mean percent change from baseline and ≥ 50% reduction from baseline (CLASI-50), which were evaluated in all patients with baseline CLASI-A scores ≥ 8 and by CLE subtypes (acute, subacute, and chronic).
- At baseline, 56% of patients had acute CLE, 29% had chronic CLE, and 16% had subacute CLE; 28% of patients had a baseline CLASI-A score ≥ 8.
- Patients were randomly assigned to receive oral iberdomide (0.45 mg, 0.30 mg, 0.15 mg, or placebo daily) for 24 weeks while continuing standard lupus medications. At week 24, patients on placebo were rerandomized to iberdomide 0.45 mg or 0.30 mg once a day, while those on iberdomide continued their assigned dose through week 52.
TAKEAWAY:
- Among patients with baseline CLASI-A ≥ 8, the mean change in CLASI-A score from baseline at week 24 was −66.7% for those on iberdomide 0.45 mg vs −54.2% for placebo (P = .295).
- At week 24, patients with subacute CLE showed a significantly greater mean percent change from baseline in CLASI-A with iberdomide 0.45 mg vs placebo (−90.5% vs −51.2%; P = .007), while no significant differences were observed with the 0.45-mg dose vs placebo in patients with chronic or acute CLE.
- Overall, CLASI-50 responses were not significantly different among those on 0.45 mg vs placebo (55.6% vs 44.6%). The proportions of patients achieving CLASI-50 at week 24 were significantly greater for iberdomide 0.45 mg vs placebo for those with subacute CLE (91.7% vs 52.9%; P = .035) and chronic CLE (62.1% vs 27.8%; P = .029), but not for those with baseline CLASI-A ≥ 8 (66.7% vs 50%).
- More than 80% of patients had treatment-emergent adverse events (TEAEs), which were mostly mild to moderate. Over 2 years, the most common were urinary tract infections, upper respiratory tract infections, neutropenia, and nasopharyngitis. TEAEs leading to iberdomide discontinuation in one or more patients were neutropenia (n = 7), rash (n = 7), increased hepatic enzymes (n = 4), and deep vein thrombosis (n = 3).
IN PRACTICE:
“Data from this phase 2 trial of iberdomide in patients with SLE suggest that a greater proportion of patients with subacute or chronic CLE who received the higher dose of 0.45 mg iberdomide achieved CLASI-50 vs placebo. For the overall population, CLASI-50 response was not significantly different between treatment groups at week 24, partly due to a high placebo response that may have been driven by patients with acute CLE,” the authors wrote.
SOURCE:
The study was led by Victoria P. Werth, MD, of the University of Pennsylvania and the Veteran’s Administration Medical Center, both in Philadelphia, and was published online in the Journal of the American Academy of Dermatology.
LIMITATIONS:
The study included small patient subgroups for different CLE subtypes, which may affect the generalizability of the findings. CLE subtype was determined by the investigator without additional photographic adjudication. Additionally, the use of background lupus medications could have influenced the placebo group’s response, limiting the ability to observe the treatment effect of iberdomide monotherapy.
DISCLOSURES:
The study was funded by Bristol-Myers Squibb. Six authors reported being employed by Bristol-Myers Squibb, and several others reported consultancy and research support from various sources including Bristol-Myers Squibb.
