Safety Study of Individual Paclitaxel Dose Adjustment Based on Pharmacokinetics in Non-Small Cell Lung Cancer (NSCLC)

Inclusion Criteria:

For inclusion in the study treatment period patients must fulfil all of the following criteria:

1. Provision of informed consent.
2. Male or female aged 18 years and over.
3. Histologically or cytologically confirmed non-small cell lung carcinoma.
4. Locally advanced Stage not amenable to local therapy (e.g. pleural effusion) or metastatic disease.
5. No prior chemotherapy, biological (including targeted therapies such as Epidermal Growth Factor Receptor(EGFR) and Vascular Epidermal Growth Factor (VEGF) inhibitors) or immunological therapy. Patients who are willing to accept with paclitaxel and carboplatin as adjuvant chemotherapy will be eligible.
6. World Health Organization (WHO) performance status (PS) of 0 to 2.
7. Females of child-bearing potential must have negative serum pregnancy test. Sexually active males and females (of childbearing potential) willing to practice contraception during the study.
8. Laboratory values within the range, as defined below, within two weeks of randomization:

   * Absolute neutrophils count(ANC)≥2.0×109/L
   * Platelets≥100×109/L
   * Serum bilirubin≤2×ULN; Aspartate transaminase(AST) and alanine tansaminase (ALT) ≤2.5×ULN(≤5×ULN if liver metastases)
   * Creatinine clearance≥60ml/min
9. Measurable disease according to Response Evaluation Criteria in Solid Tumors(RECIST) criteria with at least one measurable lesion not previously irradiated.
10. Life expectancy ≥12 weeks.

Exclusion Criteria:

Any of the following is regarded as a criterion for exclusion from the study:

1. As judged by the investigator, any evidence of severe or uncontrolled systemic disease (e.g. unstable or uncompensated respiratory, cardiac, hepatic or renal disease).
2. Newly diagnosed Central Nervous System (CNS) metastases that have not yet been definitively treated with surgery and/or radiation.
3. Known severe hypersensitivity to carboplatin, paclitaxel or any of the excipients of these products.Known severe hypersensitivity to pre-medications required for treatment with carboplatin / paclitaxel doublet chemotherapy.
4. Prior treatment with paclitaxel.
5. Current treatment with target drug and biological therapy.
6. Pregnant or lactating woman.
7. Prior chemotherapy, biological (including targeted therapies such as Epidermal Growth Factor Receptor(EGFR) and Vascular Epidermal Growth Factor (VEGF) inhibitors) or immunological therapy were received even if treatment was not paclitaxel and was completed in 4 weeks before day1 of study treatment.
8. Other co-existing malignancies or malignancies diagnosed within the last 5 years with the exception of basal cell carcinoma or cervical cancer in situ.
9. Life expectancy of less than 12 weeks.
10. Unable to tolerate carboplatin / paclitaxel doublet chemotherapy, as judged by the investigator.
