"How much do we know about other RVX molecules and what they are for?" 

 from the rvx site:

"A BRIGHT FUTURE

As apabetalone can be administered as a twice daily tablet, it will be affordable and easy to take for all patients. Most importantly, apabetalone has proven to be safe.

Due to its unique epigenetic mechanism, we continue to discover more ways that apabetalone can benefit patients across a broader range of chronic diseases, including neurodegenerative diseases, peripheral artery disease and a number of rare diseases"

ya they "continue to discover more ways" but they got no fricking money & pee poor management to turn any of it into something bigger! Thats the fricking problem as stated by narmac & others numerous times. Its no secret for gods sake.
