RoosterBio Inc, a leading supplier of human Mesenchymal Stem/Stromal Cell (hMSC) working cell banks and hMSC-specific bioprocess systems, announces today it has submitted a U.S. Food and Drug Administration (FDA) Type II Master File (MF) for its CliniControl™ line of cGMP hMSC working cell banks. This MF complements the MF for the CliniControl RoosterNourish™-MSC-CC bioprocess media that was filed in 2017. The MFs contain confidential information on the products including their chemistry, manufacture, and controls. This enables RoosterBio to protect proprietary product information yet allows the FDA to review the information in support of an investigator’s submission. Upon request, RoosterBio will grant a customer authorization to cross reference the stated MF(s) to support their own regulatory filing, such as an Investigational New Drug (IND) application to the FDA. INDs are filed with the FDA prior to beginning clinical evaluation of new therapeutic products in human subjects.
