Most cancer clinical trials are treatment studies that involve people who have cancer. After treatment is tested in the lab or on animals (called preclinical testing), it enters a phase 1 clinical trial that involves testing on humans. Clinical Research Courses Determine What Patients Want From a Clinical Trial - In the present times, sponsors and investigators require patient centricity in order to design more effective clinical trials. For example, they might be prevention trials, treatment trials or diagnostic and screening trials. Dept. Clinical trials can be used as a method to study a wide range of interventions, and by a range of individuals or as we keep referring to them – sponsors. The idea is to help you form a basic understanding of clinical trials. Phase I Trials A phase I trial is the first test of a new treatment, and it uses the fewest number of patients (20-30 patients is typical). Clinical trials may be conducted on people who have a disease or on healthy people, depending upon the purpose of the research. Approaches to surgery or radiation therapy 4. They aim to find out things such as whether patients and doctors are happy to take part, and how long it might take to collect and analyse the information. Biomedical clinical trials of experimental drug, treatment, device or behavioral intervention may proceed through four phases: Phase I. clinical trials test a new biomedical intervention in a small group of people (e.g., 20-80) for the first time to evaluate safety (e.g., to determine a safe dosage range, and to identify side effects). (Pharmacology) Here one thing should be noted that types of clinical trials are different from types study designs used in the clinical studies. Classification of Clinical Trials There are three types of clinical trials – phase I, phase II and phase III – each one is designed to learn something different about a new medical treatment. Dr. SUMAN BAISHNAB 2. A later phase trial aims to test and compare whether a new treatment is CLINICAL TRIALS

A trial carried out by a single researcher or research team in one hospital or another type of centre. Phase III of a clinical trial usually involves up to 3,000 participants who have the condition that the new medication is meant to treat. Dr. Chintan Doshi 2.
