You never hear a thing about EXELs and Sanofi's PI3K which makes me think, like 99% of what EXEL has developed over the years, is just another major mee-too drug which will probably end up in the dumpster after spending hundreds of millions on them.
Gotta admit. Their management is freaking fantastic at getting money upfront for these mee-too's.
Heck, just look at how many compounds these guys have...partnered and unpartnered. It is ridiculous. They have nothing except for Cabo to show for it.
