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....

This course would be most useful to the participant if pursued within a short time-frame, of maximum of 6 weeks. Both lecturers were clear and good communicators. I would take more of their classes.

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.

This was a good introductory course into clinical trials, providing an overview of its principles, features and design. The lectures were good and clear, and the accompanying slides were just as useful. I will admit to being occasionally lost on certain concepts, especially with regards to those which would've normally been covered in the biostatistics class, as Ms. Drye mentioned once or twice -- after all, I believe this is a class which is probably offered in conjunction with others. That notwithstanding, I can now consider myself aptly familiar with clinical trials and what they entail, thanks to this course.

I will say, however, that having just 10 questions in the quiz is hardly neither exhaustive nor -- and I suppose this goes without saying -- a true test of a good grasp of the course. For instance, I'd read most of the supplemental material for Ethics (week 4) only to realize that that week's quiz could've been passed using common sense alone. I felt somewhat disappointed by that. And also, while one lecturer was very clear in her presentation and discourse, the other wasn't really; more often than not, I was confused by her sentences.

Excellent classes for beginners in the clinical trials.I learnt about basic knowledge, design points and constitutive interpretation for different kinds of trials~

Maybe the tests are a bit easy, apart from that the lectures are well defined and cover in detail the topics related to the course. The example trials are very well selected to understand the information of the lectures.

When I started this course, I had no idea how important it is for me to understand what goes on in the background of clinical research and how important are the ethical considerations. Now, I think I have started developing a sense of clinical research. Being a general surgeon in India, this class has helped me a lot and I hope this will benefit me and my patients with their treatment selection. I thank the instructors of this course for making it looks so simple to understand.

This course was very interesting a little hard that I had to do optional lectures to understand better, I passed the evaluation.

This course provides me with valuable new knowledge about clinical trials. Although I had taught myself before, I still get various interesting points, e.g. types of trial designs, ITT analysis, etc. Thank you very much!

A fantastic foundational course that covers all the essentials to understand and appreciate the design and interpretation of clinical trials. Lectures are succinct followed by really challenging quizzes which allows one to test his/her understanding of the subject matter.

Good course as an introduction of the topic.

This is an educational course that will introduce you many aspects of a clinical trial.

Things to improve: A. instructors/mentors are not responsive and any question that you may have, will remain unanswered and B.some videos are quite lengthy.

This was an extremely interesting course. The topics laid out week by week were adequate and easy to complete. The only issue I would point out is there was very little interaction from the course coordinators. It would have been helpful to get feedback on some of the discussion topics. I would have also liked to see explanations of some of the answers on the quizzes. A list of further reading (including suggested books, published papers, interesting articles) would have been welcome. In all, it was a very useful course, however due to some of the issues mentioned previously, I refrained from purchasing the course. Th

Was alright, but felt a bit short of content. Some more interactive assignments, questionnaires and examples would be nice.

for me personally the level was to basic. Having said that, it gives a good overview on clinical trial designs.

the lessons were too long in duration and i was really bored because the teaching didn't have anything engaging me to be more eager to listen and all the slides were with the same background and design and there were no pictures or animation or fun stuff to create some kind of diversity in the progress of the course.

It is hard to describe what I didn't like about this course. I have a reasonable statistical background as well as a basic science and public health background, so I may be overly familiar with the material. I didn't find that going through the material helped me beyond what I could intuit from the basic principles of how to do a study. This isn't good, because I feel like someone without my background would be overwhelmed by the information presented and not be able to follow it. I also believe the lecture style was too conversational and not very organized. It feels like a little bit too much like the introduction to a journal club with 3rd year graduate students. The course should be for novices. Ultimately, everything felt like it was being described rather than taught. One positive I can say, is that I think the basic contents of the course are good, they just need to be organized properly and distilled down and focused. Instructors should resist any urge to randomly jump into discussions which are above the intended level of the course.

Some of the videos are excessively long. All lectures are just written slides and narration, there isn't even a human figure in the videos, no interaction what so ever; making the videos a bit boring. The content is good it's like a concise comprehensive view on clinical trials.
