SUPPLEMENTARY INFORMATION: 

I. Background

    In the Federal Register of July 12, 2018, FDA published notices of 
availability with a 90-day comment period for six draft guidance 
documents listed in the following table. Three of the six draft 
guidance documents provide recommendations to stakeholders developing 
gene therapies for retinal disorders, hemophilia, and rare diseases. 
The remaining three guidance documents provide recommendations to 
sponsors manufacturing gene therapies; namely, how to provide 
chemistry, manufacturing and controls information for gene therapy 
products, additional recommendations regarding the testing for 
replication competent retrovirus during the manufacture of retroviral 
vector-based gene therapy products and during the follow-up monitoring 
of patients who received retroviral vector-based gene therapy products, 
and recommendations regarding the design of long-term follow-up 
observational studies for the collection of data on delayed adverse 
events following administration of a gene therapy product. Comments 
were requested on these draft guidances by October 10, 2018.

------------------------------------------------------------------------

    The Agency has received requests for a 60-day extension of the 
comment period for the six draft guidance documents. These requests 
conveyed concern that the current 90-day comment period does not allow 
sufficient time to develop a meaningful or thoughtful response to the 
draft guidance documents.
    FDA has considered these requests and is extending the comment 
period for the six draft guidance documents for 60 days, until December 
10, 2018. The Agency believes that a 60-day extension allows adequate 
time for interested persons to submit comments.
