RESUMO
BACKGROUND: Daratumumab is used in the treatment of relapsed multiple myeloma. Daratumumab infusion-related reactions can occur with the highest incidence on the first infusion. METHODS: A retrospective review of all daratumumab infusions used as part of the DVd and DRd regimens for relapsed multiple myeloma was undertaken. The review of infusion-related reactions was conducted by reviewing the treatment room nursing note on the days that daratumumab was administered. If the patient experienced an infusion-related reaction, then the data captured included if the full dose was administered. RESULTS: Daratumumab infusion-related reactions occurred most frequently on the first dose. The rates of infusion-related reactions using a split dose approach for daratumumab administration were lower than that reported in clinical trials. All of the infusion-related reactions were managed with appropriate interventions in the outpatient setting. The adoption of rapid infusion daratumumab beginning with cycle 2 of DVd and DRd was well tolerated. CONCLUSIONS: Our experience of daratumumab infusions using a split dose approach was associated with an infusion-related reaction rate in 28% of patients on cycle 1, day 1 of DVd and DRd regimens. All patients were able to complete full doses of daratumumab by utilizing split dose. The rates of daratumumab infusion-related reactions are highest on the first infusion. In addition, our adoption of rapid infusion daratumumab was safe.

The product monograph for reference bevacizumab (Avastin) and biosimilar bevacizumab (Mvasi) recommend to infuse the first dose of bevacizumab over 90 min, second dose over 60 min and third and subsequent doses over 30 min. Despite the product monograph recommendations, many institutions adopted an accelerated bevacizumab (Avastin) 0.5 mg/kg/min infusion time. Our province adopted the accelerated infusion time at time of biosimilar bevacizumab (Mvasi) adoption. Our experience with the accelerated infusion time was well tolerated in the first five months of biosimilar bevacizumab adoption across different tumor types.
