What is the Purpose of Clinical Trials in Los Angeles?
According to the National Institute of Health, a clinical trial is an important part of medical research in which voluntary participants are utilized in order to strengthen medical knowledge. These medical trials allow researchers to determine new methods for the prevention, detection and treatment of human disease. Participants are subjected to specific interventions, depending on the area of medical research. Subjects may be exposed to new medications, medical techniques or devices. At the time of administration, effects that interventions will have on the participant are unknown. There are multiple types of medical trials, each with a specific purpose. These include: prevention trials, screening trials, diagnostic trials, treatment trials and quality-of-life trials. Clinical trials in Los Angeles may be conducted as randomized trials, blind trials or both.
Types of Clinical Trials
Huntsman Cancer Institute states that a prevention trial is a component of medical research that aims to determine the approach with the highest level of efficacy in terms of lowering the chances of developing a specific medical condition. This type of trial is carried out using healthy subjects and may include those that have developed the disease at some point in their lifetime and are in remission, which is helpful for figuring out which treatment best prevents reoccurrence. The trials may include studying the impact of drugs and other treatments, as well as lifestyle factors.
Screening trials are those that act to detect an illness before any symptoms are present. These medical trials are run with those who may not necessarily have the disease, and work to find out if early detection lessens the occurrence of severity or death. These trials include medical imaging and other medical testing.
Diagnostic trials consist of finding more accurate ways to identify diseases. Typically, says NIH Senior Health, participants must exhibit symptoms of the disease being studied in order to qualify for participation in a diagnostic trial. This type of trial looks at new tests and medical equipment that could make the process of diagnosis more simple and efficient.
Treatment trials are conducted with those who have been diagnosed with the disease being studied. This medical research method compares treatment options, both experimental and approved, and tries to determine the best combination of such for treatment of the illness. This includes drug therapy, psychotherapies, surgical techniques and lifestyle factors. Trials may aim to find ways to lessen severity of treatment side effects or to provide the most comfort to patients.
Quality of Life Trials
Also referred to as supportive care trials, quality of life trials looks at ways to make life for those living with a chronic illness as manageable as possible. These medical trials aim not only to help individuals with a chronic illness manage their lives better physically, but psychosocially, as well.
Clinical Trial Categorization
Randomized Clinical Trials
A randomized clinical trial is that in which participants are randomly assigned to either the experimental group (that which is given the treatment) or the control group (that which is not given any treatment or a placebo treatment). The National Institute of Health deems this practice ethical when it is unknown whether the treatment will result in better outcomes or not.
Blind Clinical Trials
There are two types of blind trials: single blind and double blind. In a single blind clinical trial, researchers are aware of which group participants have been assigned to but subjects do not know which group they are in. This is done to prevent bias responses that may arise when an individual is aware of the response the researcher is looking for. In a double blind trial, both researcher and participant do not know which group volunteers are in. This helps prevent bias influence on trial results from both the participant and the researcher.
Clinical trials are utilized to determine the best diagnostic, preventative and treatment options for specific medical illnesses. There are many different types of medical trials that allow researchers to determine the best methods for effective illness and illness-related care.
