Impact of Biologics Initiation on Oral Corticosteroid Use in the International Severe Asthma Registry and the Optimum Patient Care Research Database: A Pooled Analysis of Real-World Data.
Аннотация
BACKGROUND
For severe asthma (SA) management, real-world evidence on the effects of biologic therapies in reducing the burden of oral corticosteroid (OCS) use is limited.
OBJECTIVE
To estimate the efficacy of biologic initiation on total OCS (TOCS) exposure in patients with SA from real-world specialist and primary care settings.
METHODS
From the International Severe Asthma Registry (ISAR, specialist care) and the Optimum Patient Care Research Database (OPCRD, primary care, United Kingdom), adult biologic initiators were identified and propensity score-matched with non-initiators (ISAR, 1:1; OPCRD, 1:2). The impact of biologic initiation on TOCS (including bursts for exacerbations) daily dose in the first- and second-year follow-up period was estimated using multivariable generalized linear models.
RESULTS
Among 5,663 patients (ISAR 48%, OPCRD 52%), the odds ratios (ORs) of biologic initiators achieving TOCS cessation in the first and second years of follow-up were 2.38 (95% CI, 1.87-3.04) and 2.11 (95% CI, 1.65-2.70), whereas the ORs of low (0- to 5-mg) TOCS intake were 1.62 (95% CI, 1.40-1.86) and 1.40 (95% CI, 1.21-1.61), respectively. Compared with non-initiators, biologic initiators had a substantially higher chance of achieving greater than 75% reduction from baseline (OR [95% CI] = 2.35 [2.06-2.68] and 1.53 [1.35-1.73] in first and second years, respectively). These findings remained persistent and robust when analyses were repeated with one country setting removed at a time.
CONCLUSIONS
Biologic initiation in patients with SA led to substantial reduction in TOCS exposure, particularly in the first year. Future analyses will explore the impact on OCS-related adverse health events.
