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    FDA is announcing the availability of a draft guidance for industry 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.'' This draft guidance addresses 
nonclinical development, early phases of clinical development, and 
phase 3 protocol designs. Important issues addressed in this draft 
guidance include: Trial design options, noninferiority margin for 
active-controlled phase 3 trials in the evaluation of interferon (IFN)-
free regimens, and trial design options and safety evaluation for 
specific populations, including patients with decompensated cirrhosis, 
patients either pre- or post-liver transplant, patients with chronic 
kidney disease, and clinical virology considerations.
    This draft guidance revises the draft guidance of the same name 
that issued October 23, 2013 (78 FR 63218). Significant changes in this 
draft guidance compared to the previous version are:
     Modification of several sections to focus on IFN-free DAA 
regimens.
     Additional details on phase 2 and phase 3 trial design 
options for the evaluation of IFN-free regimens in treatment-na[iuml]ve 
and treatment-experienced populations, including DAA-experienced 
populations. Specifically, the guidance now recommends that each 
marketing application contain at least one active-controlled 
comparative trial.
     Additional clarification on DAA drug development in 
specific populations, including trial design options for human 
immunodeficiency virus/hepatitis C virus co-infected patients, 
pediatric patients, patients with advanced chronic kidney disease, 
patients with decompensated cirrhosis, patients either pre- or post-
liver transplantation, and patients who failed to respond to a prior 
DAA-based regimen.
    This draft guidance is being issued consistent with FDA's good 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 The draft guidance, when 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 current thinking of FDA on developing DAA 
drugs for treatment of chronic hepatitis C virus infection. It does not 
establish any rights for any person and is not binding on FDA or the 
public. You can use an alternative approach if it satisfies the 
requirements of the applicable statutes and regulations.

II. The Paperwork Reduction Act of 1995

    This draft guidance refers to previously approved collections of 
information that are subject to review by the Office of Management and 
Budget under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). 
The collections of information in 21 CFR part 312 have been approved 
under 0910-0014, the collections of information in 21 CFR part 314 have 
been approved under 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 
0910-0581.

III. Electronic Access

    Persons with access to the Internet may obtain the draft guidance
