RedHill Biopharma Ltd. an Israeli biopharmaceutical company together with IntelGenx Corp., a Canadian drug delivery company have announced that they received a Complete Response Letter (CRL) from the FDA regarding the New Drug Application (NDA) for RHB-103 for the treatment of acute Migraines.

The questions raised by the FDA in the CRL regarding the NDA for RHB-103 primarily relate to third party Chemistry, Manufacturing and Controls and to the packaging and labeling of the product. No questions or deficiencies were raised relating to the product's safety and the FDA�s CRL does not require additional clinical studies. While continuing to review the FDA�s CRL, RedHill and IntelGenx believe that they can supply the requested information based on available data.
