Trial ProcessA1 Clinical Network2021-09-26T11:57:13+00:00 The Clinical Trials ProcessClinical trials are designed to advance scientific knowledge while protecting the people who volunteer to participate. A1CN’s researchers must follow specific regulations to ensure patients’ safety and privacy. Lab TestingBefore a new therapy, device, or procedure is tested on humans, it is tested in a research lab and on animals. If it shows promise, it moves through a staged approach in what are called phases. Clinical Trial ProtocolsThe clinical trial protocol maps out the criteria for participation, schedule of procedures and treatments, and length of the study. Clinical Trial PhasesTests a new therapy for the first time in a small group of people to determine if it is safe, find the right dose, and learn about side effects. Involves more people to determine how well the new therapy treats a disease and whether the treatment is safe. Broadens the study to include large groups of people to determine if the new therapy works well, if it has side effects, and how it compares to other therapies. Once the U.S. Food and Drug Administration (FDA) approve the treatment, these studies evaluate the effects of new drugs and treatments over a long period of time in large groups. They are often focused on particular groups such as people of specific ages, genders, or races, or people who are taking other medications or have other diseases. Randomized Clinical TrialsPeople who volunteer for clinical trials are often assigned randomly (like the flip of a coin) to receive one treatment or another, hence the name “randomized clinical trials.” Some people will be chosen at random to receive the treatment being studied. Others may be chosen at random to receive a different therapy, such as the current standard treatment. When no standard treatment is available, some people may be chosen at random to receive an inactive treatment referred to as a “placebo.” Placebos may also be part of a study to help determine whether a therapy has a significant “placebo effect,” meaning some people respond well when they think they are receiving treatment but are not. Blinded Clinical TrialsBlinded clinical trials are studies in which the participants are randomly assigned to receive one of two or more therapies, but participants and/or researchers are kept unaware of who is receiving which therapy. In single-blinded clinical trials, only one group — either participants or researchers — is unaware of who is receiving which therapy; in double-blinded clinical trials, neither participants nor researchers know. The information is revealed if it is necessary for your safety to identify what treatment you are receiving. It is also often (but not always) revealed once the study is completed. Institutional Review Board (IRB)The IRB reviews and approves the protocol, consent form, and all other documents for each study. Its main job is to ensure the study participants are protected and that the balance of potential risks and benefits is appropriate. The IRB conducts regular reviews of each active study.
Subscribe to the newsletter© Copyright 2021 A1 Clinical Network LLC® What is it called when neither the researchers nor the participants know who received which treatment?Listen to pronunciation. (DUH-bul-blind STUH-dee) A type of clinical trial in which neither the participants nor the researcher knows which treatment or intervention participants are receiving until the clinical trial is over. This makes results of the study less likely to be biased.
What is a research design called when neither the participants?Definition. The double-blind design describes an experimental procedure in which neither the participant nor the experimenter are aware of which group (i.e., experimental or control) each participant belongs to.
What do you call it when the participant in an experiment does not know if they are in the control or experimental group?If a control group takes a placebo, participants don't know whether they are being treated or not, so they have the same expectations as members of the experimental group. However, there is also the placebo effect to consider.
What is the name for the group of study participants who do not receive any treatment or manipulation?The control group is composed of participants who do not receive the experimental treatment. When conducting an experiment, these people are randomly assigned to be in this group. They also closely resemble the participants who are in the experimental group or the individuals who receive the treatment.
