Notice; reopening of comment period. 

# SUMMARY:

                        The Food and Drug Administration (FDA) is reopening for 90 days the comment period for the notice requesting the submission of proposed product standards for unrelated allogeneic peripheral and placental/umbilical cord blood hematopoietic stem/progenitor cells. The notice was published in the                         **Federal Register**                         of January 20, 1998 (63 FR 2985). FDA is taking this action in response to a request for an extension and to allow interested parties additional time for review and to submit comments on proposed product standards.                     

# DATES:

Submit written comments by July 17, 2000.

# SUPPLEMENTARY INFORMATION:

                    In the                     **Federal Register**                     of January 20, 1998 (63 FR 2985), FDA published a notice requesting proposed product standards intended to ensure the safety and effectiveness of minimally manipulated hematopoietic stem/progenitor cells derived from peripheral and cord blood for unrelated allogeneic use. Interested persons were given until January 20, 2000, to submit written comments. On January 18, 2000, a comment requesting that the agency extend the comment period was submitted to the docket. The comment noted that comprehensive standards that cover all aspects of cord blood banking have been drafted. However, additional editing and final review is required before submission to the docket. FDA finds it appropriate to reopen the comment period to permit interested persons additional time to submit proposed product standards intended to ensure the safety and effectiveness of minimally manipulated hematopoietic stem/progenitor cells derived from peripheral and cord blood for unrelated allogeneic use. Therefore the agency is reopening the comment period for an additional 90 days, until July 17, 2000, to allow the public more time to submit proposed product standards.                 

Interested persons may submit to the Dockets Management Branch (address above) written comments on proposing product standards intended to ensure the safety and effectiveness of minimally manipulated hematopoietic stem/progenitor cells derived from peripheral and cord blood for unrelated allogeneic use by July 17, 2000. Two copies of any comments are to be submitted, except individuals may submit one copy. Comments are to be identified with the docket number found in the brackets in the heading of this document. A copy of the document and received comments are available for public examination in the Dockets Management Branch between 9 a.m. and 4 p.m., Monday through Friday. 

Dated: April 10, 2000.
