A clinical trial, also called a research study, is a research program that tests the effectiveness and safety of various interventions for people with a certain condition.Clinical trialsare meant to find new and improved methods of evaluating or treating a condition. They also can test new ways ...
Before a drug is available at the pharmacy, it is investigated in clinical trials. Clinical trials are carefully monitored and documented scientific studies to evaluate the safety and efficacy of the investigational drugs to find new and better treatments for patients. They are performed in a ...

Clinical trials are important because they improve medical research in terms of usefulness and safety. They teach investigators what does and does not work when analyzing new ways to detect, diagnose and treat disease. Clinical research can determine whether a drug under review has the desired effec...
A randomised, controlled, double blind, escalating dose study of alicaforsen enema in active ulcerative colitis Objective: To evaluate the safety and efficacy of an enema formulation of alicaforsen, an antisense inhibitor of intercellular adhesion molecule, after 1, ...

3. Harmonisation should focus on a flexible, safety-based approach. In addition to optimal compliance with the scientific, regulatory and legal aspects for initiating the first clinical trials in man, ethical considerations are important for both human exposure and laboratory animal use....
For diffuse gliomas, it is important to identify IDH mutations, given the favorable clinical behavior and potential for using FDA approved IDH inhibitors in the near future. MGMT promoter methylation testing is the most established molecular marker for response to temozolomide in IDH wild-type gliobla...
Phase 1: Researchers test the investigational drug or treatment in a small group of people to learn about its safety, including how it is absorbed by the body, what dosage should be used and potential side effects. Phase 2: The intervention is given to a larger group of people to better ...
Phase I is the first and smallest study, using groups numbering between 20 and 80 patients to test the effectiveness and optimal dosage of a drug and to identify any side effects. Phase II uses groups of between 100 and 300 people to further test the safety of the drug and to make more...
Drugs normally undergo three phases of clinical trials. In the first phase, a drug’s delivery method, dosage, and safety is tested on a small group of people. The second phase uses a larger test group. Most treatments fail in one of these phases. There are several types of clinical tria...
