 Each institution in the USA will be cross-referenced to the IND number of the US Principal Investigator 63,966. This IND number is only necessary for grant funding. The FDA has assessed this study and does not feel that it required an IND number for clinical reasons since labetalol is already an approved antihypertensive medication. The only reason that an IND number was requested was to allow us to satisfy the requirements for various Federal Funding agencies. The foreign institutions will not require an IND number but will all require an active approval from their Institutional Review Board.
