Unless you have dealt with her like Larry Smith clearly has, I won't wish to add to unnecessary speculation.
LP always has a lot on her plate. Strategically only she knows which of many paths to take weighing the pro's and con's and when. Some are out of her control like the blinded L PH3 trial. She has incredible connections: has everyone noticed the boards she's been on: Case in point: Moffit Cancer Center in Tampa, FL http://moffitt.org/ctancer-types--treatment
Liken to an Octopus with many arms to grab this or that or shelf till the stars for her are truly aligned.
