Brief Summary
By detecting the blood concentration of paclitaxel (PTX), Investigator assume this research can identify the individual differences of PTX pharmacokinetics (PK) parameters (TC\>0.05 refers to the duration of paclitaxel plasma concentration above 0.05 µmol/L) in Chinese non-small cell lung cancer (NSCLC) patients, and find the correlation between PK results and PTX toxicities and Effectiveness, acquire the optimization method of PTX, and finally try to explore the individualized PTX pharmacokinetically-guided dosing strategy. Orally administer rosiglitazone, which is a substrate of CYP2C8 the same as paclitaxel, before chemotherapy injection. Detect the blood concentration of rosiglitazone, analyze the correlation of rosiglitazone pharmacokinetic parameter and paclitaxel exposure, and explore the effect of rosiglitazone as an in vivo probe of paclitaxel exposure.
- 1.The variability of paclitaxel concentrations in the patient population dosed by body surface area (BSA), and the limitation of BSA-based dosing of paclitaxel.
- 2.Verify that paclitaxel TC\>0.05 is the most relevant predictor of haematological toxicity and clinical outcomes.
- 3.Define a dosing algorithm based on paclitaxel TC\>0.05 of paclitaxel and quantify its effect on both reducing toxicity and improving Effectiveness.
- 4.The effect of using dose modification and administration of G-CSF based on toxicity determined by paclitaxel TC\>0.05 measurement.
- 5.Construct a trial outline with the aim of reducing grade 4 neutropenia toxicity and ensuring the clinical outcome by using individual dose adjustments based on the dosing algorithm.
- 6.Detect the blood concentration of rosiglitazone after orally administration, explore the effect of rosiglitazone as an in vivo probe of paclitaxel exposure based on CYP2C8 activity. Attempt to establish a model to predict the paclitaxel exposure of patients base on rosiglitazone blood concentration before chemotherapy.
