Effect of daclizumab high-yield process in patients with highly active relapsing-remitting multiple sclerosis.

ABSTRACT: Patients with highly active relapsing-remitting multiple sclerosis (RRMS) are at greater risk for disease progression and may respond differently to MS therapeutics than those with less active disease. The current post hoc analysis evaluated the effects of daclizumab high-yield process (DAC HYP) vs. placebo in patients with highly active RRMS in the SELECT study. Highly active RRMS was defined as patients with ≥2 relapses in the year before randomization and ≥1 gadolinium-enhancing (Gd(+)) lesion at baseline. Because results were similar in the DAC HYP dose groups, data from the DAC HYP arms were pooled for analysis. Treatment with DAC HYP resulted in similar effects in highly active (n = 88) and less active (n = 506) RRMS patients. DAC HYP reduced the annualized relapse rate by 50 % and 51 % in the highly active (p = 0.0394) and less active (p < 0.0001) groups vs. placebo, respectively (interaction p = 0.82). DAC HYP reduced new/newly-enlarging T2 lesions (highly active RRMS 76 % reduction, p < 0.0001; less active RRMS 73 % reduction, p < 0.0001; interaction p = 0.18), the risk of having more Gd(+) lesions (highly active RRMS 89 % reduction, p < 0.0001; less active RRMS 86 % reduction, p < 0.0001; interaction p = 0.46), and sustained disability progression (highly active RRMS 88 % reduction, p = 0.0574; less active RRMS 46 % reduction, p = 0.0383; interaction p = 0.22) vs. placebo. DAC HYP efficacy was similar across the spectrum of MS disease activity as assessed prior to treatment initiation.

Project description:IntroductionCutaneous adverse events (AEs) have been observed in clinical studies of daclizumab high-yield process (HYP) in relapsing-remitting multiple sclerosis (RRMS). Here, we report cutaneous AEs observed in the randomized, double-blind, active-comparator DECIDE study (ClinicalTrials.gov identifier, NCT01064401).MethodsDECIDE was a randomized, double-blind, active-controlled phase 3 study of daclizumab HYP 150 mg subcutaneous every 4 weeks versus interferon (IFN) beta-1a 30 mcg intramuscular (IM) once weekly in RRMS. Treatment-emergent AEs were classified and recorded by investigators. Investigators also assessed the severity of each AE, and whether it met the criteria for a serious AE. Cutaneous AEs were defined as AEs coded to the Medical Dictionary for Regulatory Activities System Organ Class of skin and subcutaneous tissue disorders. The incidence, severity, onset, resolution, and management of AEs were analyzed by treatment group.ResultsCutaneous AEs were reported in 37% of daclizumab HYP-treated patients and 19% of IFN beta-1a-treated patients. The most common investigator-reported cutaneous AEs with daclizumab HYP were rash (7%) and eczema (4%). Most patients with cutaneous AEs remained on treatment (daclizumab HYP, 81%; IM IFN beta-1a, 90%) and had events that were mild or moderate (94% and 98%) and subsequently resolved (78% and 82%). Most patients with cutaneous AEs did not require treatment with corticosteroids or were treated with topical corticosteroids (daclizumab HYP, 73%; IM IFN beta-1a, 81%). Serious cutaneous AEs were reported in 14 (2%) daclizumab HYP patients and one (<1%) IM IFN beta-1a patient.ConclusionThere was an increased risk of cutaneous AEs with daclizumab HYP. While physicians should be aware of the potential for serious cutaneous AEs, the typical cutaneous AEs were mild-to-moderate in severity, manageable, and resolved over time.FundingBiogen and AbbVie Biotherapeutics Inc.Trial registrationClinicalTrials.gov identifier, NCT01064401.
