phase i study of the combination of anlotinib with pemetrexed or docetaxel

Conditions: Non-squamous Non-small Cell Lung Cancer

Summary: the purpose of this clinical study is to evaluate the tolerability and toxicity of different dose of anlotinib puls pemetrexed/docetaxel in second-line treatment of advanced gene negative non-squamous non-small cell lung cancer , to provide a reference of dosage for phase ii clinical trials

this is a randomized, single -center study conducted in china to compare the tolerability and toxicity of different dose of anlotinib plus pemetrexed / docetaxel in patients of advanced gene negative non-squamous non-small cell lung cancer.from low dose group up to high dose group, each one had 3 patients at least.primary group received anlotinib 8mg. the dose of anlotinib would increase gradually until mtd. eligible patients will be randomized to arm a and arm b: arm a: patients were instructed to take folic acid 400ug orally daily beginning 1 week before the first dose of pemetrexed and continuing daily until 3 weeks after the last dose of pemetrexed. a 1000ug b12 injection was administered intramuscularly approximately 1 week before the first dose of pemetrexed and was repeated approximately every 9 weeks until after discontinuation. all target volumes were instructed to take dexamethasone (4 mg orally twice daily the day before, the day of, and the day after pemetrexed) as a prophylactic measure against skin rash. patients on the pemetrexed arm received 500mg/m2 pemetrexed as a 10-minute intravenous infusion on day 1 of a 21-day cycle and 8mg/10mg/12mg anlotinib orally daily on day 1 to 14 of a 21-day cycle. arm b: patients on the docetaxel arm received 60mg/m2 docetaxel as a 10-minute intravenous infusion on day 1 of a 21-day cycle and 8mg/10mg/12mg anlotinib orally daily on day 1to 14 of a 21-day cycle. approximately 18 patients will be enrolled to ensure that roughly 9 patients per arm complete treatments for primary endpoint analysis.
