简要总结
This study is a phase 1, open label, randomized, three-way crossover, single dose, oral- administration of Andrographis paniculata and Metformin in healthy volunteers under fasting condition. The study will demonstrate the pharmacokinetics profile and pharmacodynamic through metabolic pathway analysis for Andrographis paniculata and Metformin.
详细描述
This is a phase 1, open label, randomized, three period, crossover, single dose oral administration of Andrographis Paniculata 1000mg, 2000mg and Metformin 1000mg clinical trial in healthy volunteers under fasting condition. Approximately 18 healthy volunteers will be enrolled into this study.
The healthy volunteers will be screened for inclusion and exclusion criteria. Eligible subjects will be enrolled into either Metformin 1000mg tablet, Andrographis Paniculata 1000mg or 2000mg capsule in a ratio of 1:1:1 in period 1 for single dose oral administration. Subjects will then undergo a washout period of at least 7 days. After the washout period, subjects will crossover over to another investigational product according to the randomization sequence.
Subjects will fast overnight prior to dosing. The volunteers will be admitted to Clinical Investigation Center ward at 7 am in the morning and will confine in air-conditioning environment with beds and chairs. The means during the stay at CIC ward will be provided to the subjects. The dosing will be performed at 8am. A series of plasma will be collected at 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 12 and 24 hours post-dose. Urine samples will be collected at 0, 0-4 hours, 4-8 hours and 8-12 hours.
A safety follow-up call will be made to subjects to record any adverse events that occurred post-dosing within 1 week.
