Efficacy of bepotastine compared with hydroxyzine in preventing rituximab-induced infusion-related reactions in non-hodgkin lymphoma patients: a phase II, double-blind, multicenter, and randomized trial
Abstract
Background: This study evaluated the efficacy of hydroxyzine and bepotastine, first- and second-generation H1 receptor antagonists (H1RA), as pretreatments to prevent infusion-related reactions (IRRs) during the initial rituximab infusion in patients with non-Hodgkin lymphoma.
Methods: In this double-blind, multicenter, randomized phase II study, 40 patients received hydroxyzine or bepotastine with acetaminophen 30 min before rituximab infusion. Primary endpoint was incidence of ≥ grade 2 IRRs based on the National Cancer Institute Common Terminology Criteria for Adverse Events. Secondary endpoints included IRRs severity, time to IRR onset, and H1RA-induced drowsiness.
Results: Incidence of ≥ grade 2 IRRs was 52.4% and 31.6% for the hydroxyzine (n = 21) and bepotastine (n = 19) groups, respectively (P = 0.184). Distribution of initial and maximum IRR grades in the two groups was not statistically significant (P = 0.846 and 0.555). Median time (range) to IRR onset in the two groups was 67 (12-112) and 62 (10-119) min, respectively (P = 0.981). Median visual analog scale score (range and 75th percentile) for drowsiness was 37 (0-100, 46) and 12 (0-100, 29) mm in the two groups, respectively (P = 0.138). Incidence of ≥ grade 2 IRRs in the absence of bone marrow infiltration was 43.8% and 14.3% in the two groups, respectively (P = 0.118), and no group differences were observed with bone marrow infiltration.
Conclusions: Bepotastine did not show significant superiority over…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 40 participants or records.
