Dear Professor, I am trying to implement the work done by Suyu Liu, “A Bayesian Phase I/II Trial Design for Immunotherapy”, using R, since the code attached with that work takes a lot of time (more than 20 hours and the code not complete, I do not know how it produced the tables and the figures). So that I tried to use trialr package trying to get similar or approximate results using the utility functions for sensitivity analysis in table 1 (picture below), but this package allowed me to use just two outcomes ( toxicity, efficacy ) and the work of Liu used three outcomes (immune response, toxicity, and efficacy). I want to see if I used the correct utility (table 1 below) and to see how to add a third outcome ( immune response ) to the model? (Question 1) I attached to you the code and the output for 50 iterations and 60 patients from the work of Liu and Yuan ( I cannot do more, it took around 12 hours), if you know how he produced the results, (Question 2) I hope you can feed me back. My goal is: to use their idea to select the best dose in the first stage and to continue in a second stage with only 2 arms clinical trial and the best dose. (may there is another way to do that?)

This is very detailed, thorough and informative. Thank you.
This was a great overview. Thanks for making this available online !
Thanks a lot. this was a great overview
Thanks for the overview .
Great Video, Great for CRA'S
Clear and concise informative overview.
Very helpful to understand the clinical trial process
Wonderful presentation
Thank you

@@luvkashyap ok
Is there any free certification bodies or institution for clinical trials course
Nice

I need know about the opiate
Very good
hi guys. has anybody been already in such clinical trial? have you had any serious or permanent side effect??
What is the difference between phase 2 and 3 though ?
Phase 3 it is always randomised. There are from hundreds to thousands of patients under investigation, compared to the 100 to 500 patients in phase 2.
