Efficacy of nivolumab four-weekly dosing schedule based on body weight

摘要

Nivolumab has received regulatory approval to be given by weight-based or flat dosing every two weeks or by flat dosing every four weeks. However, flat dosing would lead to unnecessarily high doses for patients with lower body weight, increasing the drug usage and probability of toxicity. We review the rationale of using a four-weekly hybrid dosing strategy using weight-based and flat-dosing regimens adopted by some jurisdictions.
