The new model, a so-called "phase 0" clinical trial, promises to streamline the costly and time-consuming drug development process, helping to deliver good drugs to people who need them more quickly. Scientists look at how the body reacts to the drug and how it acts in the body. In a phase I study, the goal is to determine the best way to administer a drug and the maximum dose tolerated with the fewest side effects. As the name implies, a phase 0 trial precedes "phase I" testing, traditionally the first step in the process of human drug testing. Phase 0 studies expose a small number of people to low doses of a drug over a limited period of time -- seven days or less. "We want to find out if they're ineffective in the smallest number of patients and get definitive information as alyosha in the development process as possible," said Dr. Doroshow, director of the division of cancer treatment and diagnosis at the National Cancer Institute in Bethesda, Md. If not, a decision can be made to scrap the drug before it goes on to further, more costly development and testing. If the drug hits its intended target without producing significant side effects, the next phase can be expedited. | jon lauren apparel - boys swimsuit, royal, white jon lauren apparel - boys swimsuit, navy blue jon lauren apparel - boys swim suit, royal blue jon lauren apparel - boys swimsuit, red jon lauren apparel - boys swimsuit, khaki jon lauren apparel - boys swimsuit, black jon lauren apparel - boys swimsuit, navy, white jon lauren apparel - boys swimsuit, lime, white jon lauren apparel - boys swimsuit, black, white jon lauren apparel - boys swimsuit, red, white jon lauren apparel - boys swimsuit, turquoise, white jon lauren apparel - boys swim suit, royal jon lauren apparel - boys swim suit, royal, white jon lauren apparel - boys swim suit, navy blue jon lauren apparel - big mens swim suit, royal blue jon lauren apparel - big mens swimsuit, red |
