Trial Outcomes & Findings for Efficacy of Montelukast in Reducing the Incidence and Severity of Monoclonal Antibodies Associated Infusion Reactions (NCT NCT04198623)

NCT ID: NCT04198623

Last Updated: 2025-12-15

Results Overview

The incidence rate of infusion reaction includes all clinical sign and symptoms of reaction graded by CTCAE v5.0 in patients receiving each cycle monoclonal antibody infusions. The grade and rate of each grade will be measured and or calculated for each cycle of infusion up to 6 cycles or treatment discontinuation which ever comes first

PRIMARY outcome

Timeframe: Through study completion (average 6 months)

Population: The incidence rate of all grades of infusion reaction on the day of infusion during or after administration of cycle 1 of Monoclonal Antibody treatment in all participants

The incidence rate of infusion reaction includes all clinical sign and symptoms of reaction graded by CTCAE v5.0 in patients receiving each cycle monoclonal antibody infusions. The grade and rate of each grade will be measured and or calculated for each cycle of infusion up to 6 cycles or treatment discontinuation which ever comes first

SECONDARY outcome

Timeframe: Through study completion (average 6 months)

Population: Total population is separated to the differing monoclonal antibody treatment regimen

The time from start to end of each cycle of infusion of monoclonal antibody will be measured in the study subject up to 6 cycles or treatment discontinuation which ever comes first. Average infusion time will then be calculated.
