GP - Thanks for tweaking my thoughts. I think I have it figured out now but still open to be corrected. From what I have now read, I believe this is the story. Apabetalone has been GRANTED BTD. I don't think BTD's are APPROVED. The lists found on the FDA site appear to be drugs that were granted BTD and have now been APPROVED for sale. All 6 of them are drugs on sale now and the approval for sale dates of some do fit the dates on these lists. Some were already approved and now are for use with other drugs for certain treatments. Apabetalone is in the middle of this process with a BTD GRANTED but still working toward FDA APPROVAL for sale. That is why it does not show up on the FDA APPROVAL lists.
