I wanted to add, the NDA filing isn't just about getting a drug approved it's safe to use. It's also about getting FDA ok to market it and lable it. Manufacturing is part of the approval process to my understanding. If IPCI isn't manufacturing it on their own, they have a partner doing it for them. Without this finalized, FDA won't approve Rexista and can't continue further.
We all know IPCI don't market their own products, so it makes no sense if they are just finding a manufacturer to make the drug without selling it. Naturally, they have to have a manufacturer selected and is able to help them sell the drug. I just don't know the hold ups and what they are planning exactly.
