Trial Outcomes & Findings for Treatment of Refractory Nausea and Vomiting in Patients With Breast Cancer (NCT NCT03367572)

NCT ID: NCT03367572

Last Updated: 2025-09-25

Results Overview

Will be measured on a 7-point scale ("1: not at all nauseated", "4: moderately nauseated", "7: extremely nauseated"). Higher score is a worse outcome. This is averaged over 15 assessment points for Cycle 1 (Day 1 measured at afternoon, evening and night and Days 2 through 4 measured at morning, afternoon, evening and night). This is averaged over 16 assessment points for Cycle 2 (Days 1 through 4 measured at morning, afternoon, evening and night).

Participant Flow

1363 subjects were enrolled. CYCLE 1 which is the First Chemotherapy Cycle (excluded 796 \[5 registration errors, 41 no four-day home record, 750 did not have average score of 3 or better\]) CYCLE 2 which is the Second Chemotherapy Cycle (excluded 250 \[subject decided not to continue on cycle 2\]). 317 subjects are available for randomization. 310 subjects were actually randomized.

PRIMARY outcome

Timeframe: Nausea measured at Cycle 1 Chemotherapy (15 time points which is Days 1,2,3,4) and also measured at Cycle 2 Chemotherapy (16 time points which is Days 1,2,3,4)

Will be measured on a 7-point scale ("1: not at all nauseated", "4: moderately nauseated", "7: extremely nauseated"). Higher score is a worse outcome. This is averaged over 15 assessment points for Cycle 1 (Day 1 measured at afternoon, evening and night and Days 2 through 4 measured at morning, afternoon, evening and night).

SECONDARY outcome

Timeframe: Nausea measured at Cycle 1 Chemotherapy (15 time points which is Days 1,2,3,4) and also measured at Cycle 2 Chemotherapy (16 time points which is Days 1,2,3,4)

Will be measured on a 7-point scale anchored by "1:not at all nauseated" and "7:extremely nauseated". Higher score is a worse outcome. This is averaged over 15 assessment points for Cycle 1 and 16 assessment points for Cycle 2. This will be assessed by estimating the contrast D = (3 - 1) - (2 - 1), where 3 is the Arm 3 mean, 2 is the Arm 2 mean, and 1 is the Control mean.
