I am not talking about NDA's in general. I am merely stating that no one in their right mind would divulge information about a trial that is not yet public information without an NDA. Each situation is different and between companies that do business in the same industry, it is often not used, as there's really no need to sign one. The element of access is easily proven by circumstantial evidence. This is a completely different situation. They are not in the same business and a trade secret is not involved.
