Real World Pharmacokinetics of Immune Checkpoint Inhibitors (ELICIT)

May 26, 2023 updated by: Radboud University Medical Center

Rationale: Real-world pharmacokinetic data from cancer patients treated with immune checkpoint inhibitors (ICIs) are sparse. Moreover, pharmacokinetic parameters may be associated with response to ICI treatment and may act as a predictive or early response biomarker.

Objective: To describe the real-world pharmacokinetics of ICIs in patients eligible for ICI treatment or already treated with ICIs.

Study design: A low-interventional cross-sectional pharmacokinetic study. Study population: Patients treated with ICIs. Intervention: A maximum of 13 blood samples (39 mL) will be derived from subjects on treatment. After discontinuation of ICI treatment, a maximum of 7 blood samples (21 mL) will be derived.

Main study parameters: Real- world pharmacokinetic parameters of ICIs: clearance, volume of distribution, serum exposure (serum concentration - time curve).

baseline clearance, change of clearance during treatment
t=0 until t=12 months or end-of-treatment, whichever comes first (on-treatment) and t=0 until max. t=26 weeks (after discontinuation)(depends on ICI used)
Real-world pharmacokinetic parameters --> volume of distribution
Time Frame: t=0 until t=12 months or end-of-treatment, whichever comes first (on-treatment) and t=0 until max. t=26 weeks (after discontinuation)(depends on ICI used)
volume of distribution
t=0 until t=12 months or end-of-treatment, whichever comes first (on-treatment) and t=0 until max. t=26 weeks (after discontinuation)(depends on ICI used)
