ASTM Proposes Standard on cellular therapy delivery devices.
Press Release Summary:
Nov 13, 2014 - ASTM WK46706, Guide for Medical Device Compatibility with Delivered Cellular Therapies, will outline parameters to consider when designing benchtop tests to assess potential impact of delivery device on dispensed cellular product. To help eliminate confusion and provide guidance on how to measure effects of devices on delivered cells, proposed standard will be divided intoÂ 3 sections: acceptable representative cell type or reporter cell system,Â cell physiology parameters, and testing.
Original Press Release
Cellular Therapy Delivery Devices Will Be Focus of Proposed ASTM Medical Standard
Press release date: Oct 30, 2014
The proposed new standard is ASTM WK46706, Guide for Medical Device Compatibility with Delivered Cellular Therapies. ASTM WK46706 will outline the parameters to consider when designing benchtop tests to assess the potential impact of the delivery device on the cellular product being dispensed.
ASTM member Carl Simon Jr., a biologist at the National Institute of Standards and Technology, notes the importance of the devices to be covered by ASTM WK46706. “Catheters and other cell delivery devices are used to deliver cell therapy products to patients. For instance, a catheter may be used to infuse cells into the venous or arterial vasculature of the heart to address acute ischemic injury to myocardial tissue.”
Primary users of ASTM WK46706, when approved, will be delivery device manufacturers, companies that make cell therapy products and regulatory bodies.
The proposed standard will be divided into three sections:
• The first section will outline what constitutes an acceptable representative cell type or reporter cell system if using device extracts.
• The second section will outline what parameters of cell physiology should be measured to make a determination of cytocompatibility.
• The final section will outline the thinking on testing components individually or as assembled for delivery, use of worst case setups, delivery device exposure conditions, appropriate density of cells to use during tests and similar items.
ASTM WK46706 is being developed by Subcommittee F04.42 on Biomaterials and Biomolecules for TEMPs, part of ASTM Committee F04 on Medical and Surgical Materials and Devices. F04.42 encourages interested parties, particularly experts in the delivery of cell therapy products, to participate in the development of WK46706. This includes cell delivery device manufacturers, relevant staff from regulatory bodies and experts from cell therapy product companies.
