Re: CFO
I believe Drechsler was to stay around as a consultant if needed, but don't know if that would be full time or part time:
From Nov 2016 transcripts:
Lastly, I would like to touch on my decision to resign from Insmed at the end of March 2017. As Will noted, this was a personal decision and one that was not easy, especially given the talented and passionate group that I have had the privilege to work with at Insmed. I am very proud of what we've accomplished to date, and I have every confidence that the foundation is set for sustained growth.
I will continue to be very involved over the next several months to ensure that the transition is seamless and my successor is positioned for success. I am also committed to providing Insmed with the necessary time and consulting services to support the onboarding of a new CFO. This is important to me both personally and professionally for the patients who are in need of new potential treatments like ARIKAYCE, INS1007, and INS1009
