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 hydroxyzine in preventing rituximab-induced IRRs due to the small sample size. Nevertheless, this exploratory study provides insight for further confirmatory studies.
