The Phases Of Clinical Trials: Summary Phase 1 is the first stage of research, testing for general safety with a small volunteer group. Phase 2 tests how well the treatment works on a larger volunteer group. Phase 3 evaluates how effective the treatment is in comparison to current treatments.
Types of Trials Civil Case – A trial that consists of a disagreement between two or more people or businesses. Criminal Case – A trial involving a person who has been accused of committing either a misdemeanor or a felony offense. Juvenile Case – A trial that usually involves a minor who is under the age of seventeen.
Clinical Research Coordinators interact and work with patients directly. CRCs are involved with recruitment, scheduling patient visits, and collecting patient data. CRAs do not interact with trial participants but ensure that enrollment standards are met.
Types of clinical trials Interventional trials aim to find out more about a particular intervention, or treatment. Observational studies aim to find out what happens to people in different situations. Feasibility studies are designed to see if it is possible to do the main study.
Interventional studies can be divided broadly into two main types: (i) “controlled clinical trials” (or simply “clinical trials” or “trials”), in which individuals are assigned to one of two or more competing interventions, and (ii) “community trials” (or field trials), in which entire groups, e.g., villages, ...
Screening trials test new ways for detecting diseases or health conditions. Diagnostic trials study or compare tests or procedures for diagnosing a particular disease or condition. Treatment trials test new treatments, new combinations of drugs, or new approaches to surgery or radiation therapy.
As mentioned in our publication Types of Clinical Trial Design, one of the designs is based, on the inclusion or not, of a control group to compare the effects of the investigational treatment. Trials that do not include it are called uncontrolled trials and those that do are called controlled trials.
(kun-TROLD KLIH-nih-kul TRY-ul) A clinical study that includes a comparison (control) group. The comparison group receives a placebo, another treatment, or no treatment at all.
Intervention groups, sometimes referred to as treatment groups, receive some form of intervention, such as a new reading program, designed to result in some change in behavior. Control or comparison groups do not receive the intervention.
Definition. Community intervention trials are research studies designed to evaluate the effects of public health interventions on a community-wide basis, rather than on individuals.
More info
Community trials address the efficacy of preventive interventions applied at the group level (e.g. , a social marketing campaign trial).Eligibility criteria are a critical component of clinical trials, as they define the patient population under investigation. The NIH defines a clinical trial as a research study in which one or more human subjects are prospectively assigned to one or more interventions. The function of the controlled clinical trial is not the "discovery" of a new drug or therapy. Houston Methodist is the leading hospital in Houston for delivering superior patient care.
