| clinical studies | <pharmacology> Human studies that are designed to measure the safety, efficacy, and appropriate dosage of a new drug or biological. Clinical studies routinely involve the use of a placebo group that is given an inactive substance that looks like the test product. (14 Nov 1997) |
| clinical syndrome | <syndrome> A clinical syndrome represents a typical constellation of physical (and laboratory) findings that may be seen as part of a primary disease process. A good example is shock, a clinical syndrome seen with many primary disease processes. (13 Nov 1997) |
| clinical thermometer | A small, self-registering thermometer, consisting of a simple scaled glass tube containing mercury, used for taking the temperature of the body. (05 Mar 2000) |
| clinical trial | <pharmacology> Research study conducted with patients, usually to evaluate a new treatment or drug. Each trial is designed to answer scientific questions and to find better ways to treat individuals with a specific disease. (12 May 1997) |
| clinical trial, phase I | A pre-planned, usually controlled, clinical study of the safety and efficacy of diagnostic, therapeutic, or prophylactic drugs, devices, or techniques based on a small number of healthy persons and conducted over the period of about a year in either the united states or a foreign country. (12 Dec 1998) |
| clinical trial, phase II | A pre-planned, usually controlled, clinical study of the safety and efficacy of diagnostic, therapeutic, or prophylactic drugs, devices, or techniques based on several hundred volunteers, including a limited number of patients, and conducted over a period of about two years in either the united states or a foreign country. (12 Dec 1998) |
| clinical trial, phase III | A pre-planned, usually controlled, clinical study of the safety and efficacy of diagnostic, therapeutic, or prophylactic drugs, devices, or techniques after phase II trials. A large enough group of patients is studied and closely monitored by physicians for adverse response to long-term exposure, over a period of about three years in either the united states or a foreign country. (12 Dec 1998) |
| clinical trial, phase IV | Planned post-marketing studies of diagnostic, therapeutic, or prophylactic drugs, devices, or techniques that have been approved for general sale after clinical trials, phases I, II, and III. These studies, conducted in the united states or a foreign country, often garner additional data about the safety and efficacy of a product. (12 Dec 1998) |
| controlled clinical trial | A clinical trial involving one or more test treatments, at least one control treatment, specified outcome measures for evaluating the studied intervention, and a bias-free method for assigning patients to the test treatment. The treatment may be drugs, devices, or procedures studied for diagnostic, therapeutic, or prophylactic effectiveness. Control measures include placebos, active medicine, no-treatment, dosage forms and regimens, historical comparisons, etc. When randomization using mathematical techniques, such as the use of a random numbers table, is employed to assign patients to test or control treatments, the trial is characterised as a randomised controlled trial. However, trials employing treatment allocation methods such as coin flips, odd-even numbers, patient social security numbers, days of the week, medical record numbers, or other such pseudo- or quasi-random processes are simply designated as controlled clinical trials.
