Patient recruitment is the process of finding and enrolling suitable participants for clinical trials. It is a crucial aspect of drug development and medical research, as it affects the validity, reliability, and generalizability of the results. Patient recruitment can also be challenging, time-consuming, and costly, involving various ethical ...
A clinical trial participant receives an injection. Clinical trials are prospective biomedical or behavioral research studies on human participants designed to answer specific questions about biomedical or behavioral interventions, including new treatments (such as novel vaccines, drugs, dietary choices, dietary supplements, and medical devices ...
Phases of clinical research. The phases of clinical research are the stages in which scientists conduct experiments with a health intervention to obtain sufficient evidence for a process considered effective as a medical treatment. [1] For drug development, the clinical phases start with testing for drug safety in a few human subjects, then ...
Randomized controlled trial. Flowchart of four phases (enrollment, allocation, intervention, follow-up, and data analysis) of a parallel randomized trial of two groups (in a controlled trial, one of the interventions serves as the control), modified from the CONSORT (Consolidated Standards of Reporting Trials) 2010 Statement [ 1 ] A randomized ...
Clinical equipoise allows investigators to continue a trial until they have enough statistical evidence to convince other experts of the validity of their results, without a loss of ethical integrity on the part of the investigators. Equipoise is also an important consideration in the design of a trial from a patient’s perspective.
Human subject research is systematic, scientific investigation that can be either interventional (a "trial") or observational (no "test article") and involves human beings as research subjects, commonly known as test subjects. Human subject research can be either medical (clinical) research or non-medical (e.g., social science) research. [ 1 ]
A multicenter research trial is a clinical trial that involves more than one independent medical institutions in enrolling and following trial participants. [1] In multicenter trials the participant institutions follow a common treatment protocol and follow the same data collection guidelines, and there is a single coordinating center that receives, processes and analyzes study data.
The Randomised Evaluation of COVID-19 Therapy (RECOVERY Trial) [1] is a large-enrollment clinical trial of possible treatments for people in the United Kingdom admitted to hospital with severe COVID-19 infection. [2][3][4] The trial was later expanded to Indonesia, Nepal and Vietnam. [5] The trial has tested ten interventions on adults: eight ...
