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. The course will explain the basic principles for design of randomized clinical trials and how they should be reported. In the first part of the course, students will be introduced to terminology used in clinical trials and the several common designs used for clinical trials, such as parallel and cross-over designs. We will also explain some of the mechanics of clinical trials, like randomization and blinding of treatment. In the second half of the course, we will explain how clinical trials are analyzed and interpreted. Finally, we will review the essential ethical consideration involved in conducting experiments on people....

The instructors have broken down the concepts in a very effective manner and have designed very thoughtful discussion prompts. The course really helped me understand the basics of clinical trials.

This is a very well structured course and great to have a basic and general idea of the main points to verify when either designing or, most importatnt in my case, how to evaluate publications about clinical trials. I would recommend this course for users with at least a minimum scientific background. The videos are engaging, and the reading material supplied (mostly for ethics and reporting) are complete and helps to give depth to what I learned. Congratulations to the organizers. I will definitely take more courses from this University, online, in the future.
