简要总结
Currently FDA does not accept pharmacokinetic studies to show bioequivalence of locally-acting nasal suspension formulations.
However, bioequivalence is defined as the absence of significant differences in pharmacokinetics of therapeutically equivalent drug products compared to the matching originally invented drug formulation. These there-called "generic drugs" are then interchangeable. Drug companies have to show that their generic version has the same active ingredient, the same label, is intended to be used for the same conditions or diseases and works at the same rate in the body.
The aim of the study is to determine if pharmacokinetics is sensitive to differences in the particle size distribution of two different nasal suspension formulations of mometasone furoate during charcoal block. The result from this study will aid the FDA in finding methods to ensure that generic products are the same as the trade name drugs.
详细描述
For every subject in this research study the following procedures and scheduling will take place.
During the screening visit the inclusion and exclusion criteria will be reviewed to ensure the subject is appropriate for the study. A physical examination will be performed after the vital sign measurements are obtained. Also, nasal spray application training will be performed and tolerability to charcoal block will be determined.
Screening tests will be performed within 30 days of study visit 1 and no later than 2 days before study visit 1. There will be 2 study visits in addition to the screening visit, a minimum period of 7 days should lapse between the subsequent study visits but no more than 3 weeks. The total study duration for each subject will be about 4-7 weeks.
Blood sample collection
Blood samples will be drawn by inserting an indwelling catheter for blood sample collection. Blood samples will be taken approximately 15 minutes prior to the dosing of the product (pre-dose sample) and at approximately 5, 10, 15, 30, 45, 60 minutes, 1.5, 2, 3, 4, 6, 8, 10, 12 and 14 hours post dosing. At each time point about 10 mL of blood sample will be collected via vacutainer tubes for plasma preparation and storage. At each study visit a total of approximately 160 mL blood will be collected, which makes a total of 320 mL of blood during study visits 1 and 2.
