Study of Thymosin α1 to Reduce Acute Pneumonia For Bulky None-small Cell Lung Cancer

This Phase II study is to determine the efficacy of Thymosin α1 on the frequency of radiation pneumonitis in non-small cell lung cancer with bulky tumor.

All patients received four cycles of weekly docetaxel (25mg/㎡) and nedaplatin (25mg/㎡)(DP), each of 1 day's duration, combined with split-course thoracic radiotherapy of 51 Gy in 17 fractions or 40 Gy in 10 fractions as the first course followed by a break of four weeks. Patients without disease progression had a dose of 15 Gy in 5 fractions or 24 Gy in 6 fractions as a boost. Patients were further treated with subcutaneous injections of thymosin once a week,1.6mg each time from the start of radiation to 2 months after the end of radiation. Toxicities will be graded according to CTCAE v. 4.0.
