SUPPLEMENTARY INFORMATION: 

I. Background

    FDA is announcing the availability of a draft guidance for industry 
entitled ``Chronic Hepatitis C Virus Infection: Developing Direct-
Acting Antiviral Drugs for Treatment.'' The purpose of this guidance is 
to assist sponsors in all phases of development of DAA drugs for the 
treatment of chronic hepatitis C. This guidance revises the draft 
guidance for industry entitled ``Chronic Hepatitis C Virus Infection: 
Developing Direct-Acting Antiviral Agents for Treatment'' issued in 
September 2010. Significant changes in this revision include:
     Details on phase 2 and phase 3 trial design options for 
the evaluation of interferon (IFN)-free and IFN-containing regimens in 
treatment-na[iuml]ve and treatment-experienced populations, including 
DAA-experienced populations.
     Revised primary endpoint to sustained virologic response 
at 12 weeks post-treatment cessation.
     Greater emphasis on DAA drug development in special 
populations including trial design options for human immunodeficiency 
virus/hepatitis C virus co-infected patients, patients with 
decompensated cirrhosis, and patients pre- or post-liver transplant.
     More details on clinical virology considerations for DAA 
drugs.

[[Page 63219]]

    This draft guidance is being issued consistent with FDA's good 
guidance practices regulation (21 CFR 10.115). The draft guidance, when 
finalized, will represent the Agency's current thinking on developing 
DAA drugs for the treatment of chronic hepatitis C virus infection. It 
does not create or confer any rights for or on any person and does not 
operate to bind FDA or the public. An alternative approach may be used 
if such approach satisfies the requirements of the applicable statutes 
and regulations.

information that are subject to review by the Office of Management and

The collections of information in 21 CFR part 312 have been approved 
under OMB control number 0910-0014, the collections of information in 
21 CFR part 314 have been approved under OMB control number 0910-0001, 
and the collections of information referred to in the guidance for 
industry ``Establishment and Operation of Clinical Trial Data 
Monitoring Committees'' have been approved under OMB control number 
0910-0581.
