Comparing the Rates of Hypersensitivity Reactions During First-Dose Taxane Infusions: Fixed-Rate Versus Stepwise...

Area of Science:

• Oncology
• Pharmacology
• Clinical Pharmacy

Background:

• Taxanes are chemotherapy drugs known to cause immediate hypersensitivity reactions (HSRs).
• Premedication does not always prevent HSRs to taxanes.
• The incidence of HSRs to taxanes is higher than with other chemotherapy agents.

Purpose of the Study:

• To evaluate if a titrated infusion protocol reduces first-dose HSRs to taxanes.
• To compare HSR rates between fixed-rate and titrated infusion protocols for taxanes.

Main Methods:

• Retrospective cohort study at a single infusion center.
• Compared patients receiving fixed-rate infusions versus a three-step titrated infusion protocol for their first taxane dose.
• Primary endpoint: rate of immediate HSRs during the first lifetime dose of docetaxel or paclitaxel.

Main Results:

• HSRs occurred in 7.1% of the fixed-rate group and 11.3% of the titration group (OR, 1.67; P=.1104).
• No significant difference in HSR incidence between the two groups.
• No differences observed in HSR severity or treatment discontinuation rates.

Conclusions:

• A titrated infusion protocol did not significantly reduce the incidence or severity of immediate HSRs to first-dose taxanes.
• Titration protocols may not offer additional benefits over fixed-rate infusions for taxane administration.
• Further research may be needed to explore alternative strategies for mitigating taxane-induced HSRs.
