Reminder- Survey: Value of collecting PK data in late phase clinical trials

Dear All: Recently, we requested you to fill out a survey (See below). We have received over 100 responses. Thanks for your input. Please ignore this message if you have already completed the survey. If you haven't, please take a moment to do so before COB April 21st. Your help in greatly appreciated. Best Regards Nitin Mehrotra Dear All: While sparse PK sampling in late phase trials (so-called phases 2, 3) is becoming a norm these days, the value-based proposition of sparse sampling is not well documented. Each of us might have been asked to justify the need for such sampling time and again. We are in the process of evaluating the value of sparse PK sampling in late phase trials across NDA/BLAs, and we need your blinded input via a 5 minute survey!

PS: The results from the current survey will be made publicly available via a publication of the above poster and can be used by all of us.
