Hello and thank you for your interest in clinical trials. My name is Riaz Qureshi and I'm an assistant professor in the Department of Ophthalmology and Epidemiology at the University of Colorado on the Anschutz Medical Campus. I'm an epidemiologist specializing in methods. I completed my doctorate at Johns Hopkins University in the epidemiology department, specializing in clinical trials and evidence synthesis. Today, I'm going to give a high-level overview of clinical trials.

I've broken this session into four important sections. Each of these sections and indeed many specific concepts within the sessions could be covered by entire lectures and workshops on their own. My goal is to provide a high-level overview of the distinctions and importance of trial-related concepts, designs, and considerations that you should make if you are reading a trial publication or are invited to work on a trial. If you want to run a clinical trial yourself, I recommend following this talk with more detailed courses and making friends with your local epidemiologists and biostatisticians to help you with all these considerations and make the trial the best that you can to have the greatest potential for impact. This talk will be broken down into two parts split after covering trial design concepts.

The world of trials is vast and this talk is going to fly past as we cover everything from randomization to reporting of results. Even though we will cover a lot of ground in the next hour with only a slide or two per concept, there will still be important elements of running a trial that I simply can't cover. For example, considerations of how to approach recruitment of participants, collect data, and monitor the data and your trial as it's happening. All of these are also important but beyond the scope of an overview of trial designs. Hopefully, with this talk, you'll have enough to get started and a baseline understanding of the variation that's possible when people might first say have you considered running a trial?
