LC, Kevin was what in most companies would be called tech support. He was one of many dozens who handled work such as providing technical information to external parties for use of K in clinical trials along with other similar functions. Worked in documentation and training at times.
He was not an exec running the K program. He was not some send on a mission to evaluate NWBO.
His value to NWBO was helping to setup that UCLA Keytruda combo trial. He worked on others but none launched.
He was a legit employee. But nothing close to the spin implied by the team.
