The Adenovirus Reference Material (ARM) is a purified and well-characterized wild type adenovirus (Ad5) now available to researchers worldwide. Due to the need for a common reference material, the ARM was produced with the purpose of validating assay methods and internal standards for use in developing recombinant adenovirus for gene therapy. Analysis of ARM by RP-HPLC, however, detected the presence of a contaminant peak with a distinctive A240 local wavelength maximum. The contaminant was found in all of the vials, with some variability in amount between vials. It appears that the contaminant is not associated with the virus and it is unlikely that it will interfere with the use of the ARM as a reference material. The source of the contaminant was probably a leachate or plasticizer from the tubing or containers used during the final processing step…

As you stand on the brink of finalizing your first Investigational New Drug (IND) application for a cellular therapy product, there is always the question looming in the back of your mind. “What did we forget?” Hopefully, the answer is “Nothing.” However, it is always good to undergo a review of the standard systems needed in order to transition from research to clinical manufacturing. This article describes an overview of the basic regulatory guidelines and quality systems necessary to begin clinical trials under the regulations of the Food and Drug Administration. However, this should only be considered a guideline, as it does not necessarily address the standards of other regulatory agencies. The investigational product, the clinical indication, and the manufacturing materials used in the investigational product can also change the regulatory requirements needed to proceed with the initiation of clinical trials…
