Types of Clinical TrialsPilot Studies and Feasibility Studies, Prevention Trials, Screening Trials, Treatment Trials, Multistage Multiarm Trials (MAMS), Cohort Studies, Case-Control Studies, Cross-Sectional Studies. There are several types of clinical trials for cancer, including treatment trials, prevention trials, screening tests, palliative and supportive care trials, and natural history studies. Each type of essay is designed to answer different research questions and will help researchers learn things that will help people in the future. Many newer treatment trials require people to be tested for tumors for genetic changes to see if treatments that target specific changes might work better for them than standard treatments.
Cancer prevention trials are studies with healthy people. In most prevention trials, people who participate do not have cancer, but are at high risk of developing the disease or have had cancer and are at high risk of developing a new cancer. These studies look at cancer risk and ways to reduce it. There are two types of prevention trials, action studies and agent studies.
The goal of cancer screening tests is to test new ways to detect the disease early, when it can be more easily treated. An effective screening test will reduce the number of deaths from cancer being evaluated.
clinical trials
are a type of research that studies new tests and treatments and evaluates their effects on human health outcomes. People volunteer to participate in clinical trials to test medical interventions, including drugs, cells and other biologics, surgical procedures, radiological procedures, devices, behavioral treatments, and preventive care.Clinical trials are carefully designed, reviewed and completed, and must be approved before they can begin. People of all ages can participate in clinical trials, including children. Clinical trials typically include participants from more than one medical or research institution and often from more than one country. As each country has its own requirements for clinical trial research, individual trials may be included in more than one registry and therefore appear in more than one registry database.
However, data from several clinical trial registries vary. 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. If you are considering participating in a clinical trial, feel free to ask any questions or raise any issues related to the trial at any time. Participants generally continue to see their regular healthcare providers while enrolled in a clinical trial.
Answering these questions, while giving as few people as possible an unknown treatment, often requires several clinical trials in different “phases”. Clinical trials may be sponsored or funded by pharmaceutical companies, academic medical centers, volunteer groups and other organizations, in addition to federal agencies such as the National Institutes of Health, the U. Knowing the phase of the clinical trial is important because it can give you an idea of how much is known about the treatment being studied. From basic information about cancer and its causes to detailed information on specific types of cancer, including risk factors, early detection, diagnosis and treatment options, you'll find it here.
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 reduced and offset by potential benefits. A confusing term used to indicate that a clinical trial does not have any specific methodological characteristics. Clinical research requires complex and rigorous testing in collaboration with communities affected by the disease. As research opens new doors to finding ways to diagnose, prevent, treat or cure diseases and disabilities, participation in clinical trials is essential to help us find the answers.
In addition to being monitored by an IRB, some clinical trials are also monitored by data monitoring committees (also called monitoring and data security councils). Sponsors of clinical trials can be individuals, institutions, companies, government agencies, or other organizations that are responsible for initiating, administering, or funding the clinical trial, but who do not conduct research. In a clinical trial, participants receive specific interventions according to the research plan or protocol created by the researchers. Unlike other phases of clinical trials, there is almost no chance that people participating in phase 0 trials will benefit.
