Pemetrexed, Cisplatin, and Vitamin B12 in Treating Patients With Mesothelioma of the Chest That Cannot Be Removed by Surgery
|ClinicalTrials.gov Identifier: NCT00541073|

RATIONALE: Pemetrexed may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving pemetrexed together with cisplatin and vitamin B12 may kill more tumor cells.
PURPOSE: This phase II clinical trial is studying how well giving pemetrexed together with cisplatin and vitamin B12 works in treating patients with mesothelioma of the chest that cannot be removed by surgery.
|Condition or disease||Intervention/treatment||Phase|
|Malignant Mesothelioma||Dietary Supplement: vitamin B12 Drug: cisplatin Drug: pemetrexed disodium Genetic: gene expression analysis Other: laboratory biomarker analysis Other: pharmacological study||Phase 2|
- Define an individually adapted (by dosage) protocol of pemetrexed disodium, cisplatin, and vitamin B12 in patients with unresectable pleural mesothelioma.
- Determine the relationship between pharmacokinetic and pharmacodynamic parameters (hematologic and nonhematologic).
- Analyze the inter-individual pharmacokinetic variations and the influence of the covariables on the pharmacokinetics of pemetrexed disodium.
- Analyze the impact of pharmacogenetic (MTHFR, TS, GSTpi, ERCC1, XPD) variations on the toxicity of pemetrexed disodium.
- Validate a strategy of adapting dosage.
OUTLINE: This is a multicenter study.
Patients receive pemetrexed disodium IV over 10 minutes and cisplatin IV over 2 hours on day 1. Treatment repeats every 3 weeks for up to 6 courses in the absence of disease progression or unacceptable toxicity. Patients also receive vitamin B12 intramuscularly on day -7 and then every 9 weeks until chemotherapy is completed.
Blood samples are collected during the first and third courses of chemotherapy. Samples are analyzed by pharmacogenetic (MTHFR, TS, GSTpi, ERCC1, xPD), pharmacokinetic, and other pharmacological methods.
