Brief summary

In this study the effect of substituting clemastine IV to cetirizine PO on the occurence of hypersensitivity reactions during paclitaxel chemotherapy will be investigated.

Detailed description

This is a single arm before-after study with a historic control cohort to evaluate the effect of a policy change (i.e. substitution of clemastine IV for cetirizine PO) regarding the premedication scheme on the incidence of HSR during paclitaxel based chemotherapy.

Interventions

DRUGCetirizine

Subjects were treated with a paclitaxel premedication regimen which contained oral cetirizine instead of intravenous clemastine

DRUGClemastine IV

Subjects were treated with paclitaxel premedication containing clemastine 2 mg IV

Design outcomes

Primary

MeasureTime frameDescription
Clinically relevant hypersensitivity reactionsDuring the first six cycles of paclitaxel treatment (the length of one cycle of paclitaxel treatment varies but is typically 7-21 days, depending on standard of care protocol).Hypersensitivity reactions grade 3 or higher according to CTCAE v4.03

Secondary

MeasureTime frameDescription
Hypersensitivity reactionsDuring the first six cycles of paclitaxel treatment (the length of one cycle of paclitaxel treatment varies but is typically 7-21 days, depending on standard of care protocol).Hypersensitivity reactions any grade according to CTCAE v4.03
The difference in the number of paclitaxel dosages until first occurrence of hypersensitivity reactionsDuring the first six cycles of paclitaxel treatment (the length of one cycle of paclitaxel treatment varies but is typically 7-21 days, depending on standard of care protocol).The difference in the number of paclitaxel dosages until first the occurrence of hypersensitivity reactions between the arms will be described.
The cumulative dose of paclitaxel (mg/m2) administered prior to the moment of hypersensitivity reactionDuring the first six cycles of paclitaxel treatment (the length of one cycle of paclitaxel treatment varies but is typically 7-21 days, depending on standard of care protocol).The cumulative dose of paclitaxel (mg/m2) administered prior to the moment of occurrence of hypersensitivity reaction
