To substantiate the great incentive foundations like the CFF have to support drug company programs, I offer the following:

The CFF received not just the "over $1B" I previously stated, but $3.3B US.  Great incentive to the charity and I admit I do not know whether foundations in the spaces RVX 208 might have effect operate in a similar manner.
