What are the 3 types of clinical trials?

Types of clinical trialsInterventional trials aim to learn 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 perform the main study. Treatment research usually involves an intervention such as medications, psychotherapy, new devices, or new approaches to surgery or radiation therapy.

Prevention research looks for better ways to prevent disorders from developing or recurring. Different types of preventive research may study medications, vitamins, vaccines, minerals, or lifestyle changes. Diagnostic research refers to the practice of looking for better ways to identify a particular disorder or condition. Screening research aims to find the best ways to detect certain disorders or health conditions.

Quality of Life Research explores ways to improve comfort and quality of life for people with chronic illness. Genetic studies aim to improve the prediction of disorders by identifying and understanding how genes and diseases can be related. Research in this area can explore the ways in which a person's genes make them more or less likely to develop a disorder. This can lead to the development of tailor-made treatments based on the patient's genetic makeup.

Clinical research is medical research that involves people. There are two types, observational studies and clinical trials.

clinical trial

in which observations are evaluated as they occur and the total number of participants is not predetermined but depends on the cumulative results. Factors that allow a person to participate in a clinical trial are called inclusion criteria, and factors that disqualify someone from participating are called exclusion criteria.

Clinical trials may compare a new medical approach to a standard one that is already available, with a placebo that contains no active ingredients, or with no intervention. Clinical trials can be done in many locations, including hospitals, universities, doctors' offices, and community clinics.

This is done when the clinical variables examined are soft, that is, they can be interpreted in different ways. Many people say that participating in a clinical trial is a way to play a more active role in their own health care. The nih Trials and You website is a resource for people who want to learn more about clinical trials. In general, clinical trials are designed to increase medical knowledge related to the treatment, diagnosis and prevention of diseases or conditions.

Innovative scientific advances in the present and past were only possible thanks to the participation of volunteers, both healthy and sick, in clinical research. The alleged causative agent may be a factor that is suspected of etiologically leading to a disease or treatment to prevent or ameliorate a clinical situation. Most, but not all, clinical trials in the United States are approved and monitored by an Institutional Review Board (IRB) to ensure that risks are minimal compared to potential benefits. Clinical trials are conducted only after preclinical findings indicate that the new drug or treatment is likely to be safe and work in people.

While most clinical trials provide participants with medical products or interventions related to the disease or condition being studied, they do not provide long-term or comprehensive medical care. A clinical trial can also look at how to improve the lives of people living with a life-threatening disease or chronic health problem. .
