A Three-Step Taxane Titration Protocol Decreases Hypersensitivity Reactions During First and Second Exposures

Area of Science:

• Oncology
• Pharmacology
• Clinical Pharmacy

Background:

• Patients receiving taxanes face a risk of hypersensitivity reactions (HSRs), particularly with initial exposures.
• Immediate HSRs can necessitate emergency care and disrupt preferred cancer treatment regimens.
• Current practices lack standardized taxane titration protocols to prevent HSRs.

Purpose of the Study:

• To evaluate if a gradual, three-step infusion rate titration reduces the incidence and severity of immediate HSRs.
• To assess the impact of titration on first and second lifetime exposures to paclitaxel and docetaxel.

Main Methods:

• Prospective, interventional study with historical comparisons.
• Evaluated 222 infusions of paclitaxel and docetaxel (99 titrated, 123 nontitrated).
• Intervention involved a three-step infusion rate titration at the start of first and second exposures.

Main Results:

• The titrated group showed significantly fewer HSRs (7%) compared to the nontitrated group (19%; P = .017).
• No significant difference in HSR severity was observed between groups.
• No titrated patients required emergency epinephrine or transfer, unlike four in the nontitrated group. Treatment completion was higher in the titrated group.

Conclusions:

• A standardized, three-step infusion rate titration effectively prevents HSR occurrence in patients receiving taxanes.
• The titration method addresses practical issues for feasibility and sustainability in clinical practice.
