Clinical trials are experiments designed to evaluate new interventions to prevent or treat disease in humans. The interventions evaluated can be drugs, devices (e.g., hearing aid), surgeries, behavioral interventions (e.g., smoking cessation program), community health programs (e.g. cancer screening programs) or health delivery systems (e.g., special care units for hospital admissions). We consider clinical trials experiments because the investigators rather than the patients or their doctors select the treatment the patients receive. Results from randomized clinical trials are usually considered the highest level of evidence for determining whether a treatment is effective because trials incorporates features to ensure that evaluation of the benefits and risks of treatments are objective and unbiased. The FDA requires that drugs or biologics (e.g., vaccines) are shown to be effective in clinical trials before they can be sold in the US.

A very good course for beginner to get a hang of how clinical trial works in real world setting. Instructors give lots of real Clinical Trials that help us link to the course materials.
Excellent beginner course on design and interpretation of clinical trials, complements a lot of what I reviewed on my classes and I would like to take a more advanced course on the topic. Thank you.
Great course! I was completely new to clinical trials, and now I feel that I can use what I learned to look for a job. Everything is explained very clearly. Thank you so much this course!
As a new learner of clinical trials, I learned a lot about the design of randomized clinical trials and the various factors that could impact the outcomes. I thorough;y enjoyed the course.
