When new drugs and devices are being evaluated for safety and effectiveness in humans, researchers conduct clinical trials. Clinical trials are the final stages of a research process designed to determine new ways to prevent, detect or treat diseases. They are at the core of the health care ind...
PIVOTAL PHASE-III CLINICAL TRIALEXPERIMENTAL METHODOLOGYThe use of meta-analysis in clinical research, although widely diffused, is likely to be abused, especially when the purpose is that of confirming a hypothesis, in order to have drugs approved. In this context, the use of meta-analysis is...
To obtain approval to market a new drug in the United States, Canada, the European Union, and most other countries, a series of clinical trials on patients is required. The extent of the trials depends on the drug (already approved for other uses or formulations, a new breakthrough product...

aThe Four Phases of Clinical Development 四个阶段临床发展[translate] aClinical development is the process of testing a drug in human subjects. A progression of increasingly complex and challenging studies is used to prove that a drug is safe and effective in treating specific conditions in certain...
The paper presents descriptive results on the estimated relationship between a particular drug's characteristics such as therapy category, route of administration and originator's size, and that drug's pathway through the three stages of human clinical trials and regulatory review. The results suggest...
A method of performing interactive clinical trials for testing a new drug comprising performing a pre-clinical phase in which a computer model for pharmacokinetics and pharmacodynamics of the drug is created and adjusted based on in vitro studies and in vivo studies in animals. A phase I clinical...

Clinical trials and clinical research are important for the progress of modern medicine. There are five types of clinical trials. Some are paid clinical trials, and some aren't. Learn the types, as well as the different clinical trial phases. Discover th
functions in the context of the complexities of vulnerable populations, including the example of medicines research for paediatric populations. We also discuss the special role of epidemiology in pre-approval drug development and the impact on epidemiological science of changes to the pharmacovigilance ...
