Pemetrexed is a multi-targeted folate antagonist, which is primarily indicated for the treatment of advanced non-small cell lung cancer (NSCLC) and mesothelioma. Dosing of cytotoxic agents like pemetrexed requires balancing the dual risk of sub-therapy and toxicity. Administration of pemetrexed to patients with a creatinine clearance <45 ml/min is currently not advised. Pemetrexed is dosed based on body surface area (BSA), while renal function and dose are the sole determinants for systemic exposure. This causes 3 major issues:
- In patients with renal dysfunction, BSA-based dosing may lead to haematological toxicity
- Patients have to discontinue treatment due to declining renal function, and are withheld effective treatment
- Even in patients with adequate renal function (GFR >45 ml/min) treatment may be improved by individualized dosing based on renal function, resulting in less toxicity. Also, BSA-based dosing may lead to ineffective therapy in patients with above average renal function.
The investigators aim to address these problems.
Objective: The overall main objective is to develop a safe and effective individualized dosing regimen for pemetrexed.
Study design: IMPROVE-III is an explorative microdosing study to assess the extrapolability of microdose-pharmacokinetics to the pharmacokinetics of a therapeutic dose.
Study population: IMPROVE-III includes 10 patients of IMPROVE-I and/or IMPROVE-II.
Intervention: patients will be administered a microdose with subsequent pharmacokinetic assessment.
Main study endpoints: The predictive performance of microdosing to predict full dose pharmacokinetics
