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.

I would highly recommend this course as I found it well-structured and helpful. After studying all the materials, I gained a great amount of knowledge in designing and interpretating clinical trail.
The powerpoints and audio lectures are very clear and concise, much appreciated. I would also appreciate more exercises or reading materials, to help solidify our understanding of the topics.
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.
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.
