Hepatitis B Virus Infection: Developing Drugs for Treatment.'' The 
purpose of this guidance is to assist sponsors in the clinical 
development of drugs and biologics for the treatment of chronic 
hepatitis B virus (HBV) infection from the initial investigational new 
drug application (IND) through the new drug application (NDA)/biologics 
license application (BLA) and postmarketing phases. This guidance 
finalizes the draft guidance of the same title issued on November 2, 
2018.

DATES: The announcement of the guidance is published in the Federal 
Register on April 7, 2022.

ADDRESSES: You may submit either electronic or written comments on

SUPPLEMENTARY INFORMATION: 

I. Background

    FDA is announcing the availability of a final guidance for industry 
entitled ``Chronic Hepatitis B Virus Infection: Developing Drugs for 
Treatment.'' The purpose of this guidance is to provide general 
recommendations on the clinical development of drugs and biologics for 
the treatment of chronic HBV infection from the initial IND through the 
NDA/BLA and postmarketing phases. The guidance includes general 
considerations for nonclinical toxicology and virology studies, early 
phase clinical development, clinical pharmacology assessments, and 
phase 3 safety and efficacy trials. The guidance discusses phase 3 
trial design considerations and efficacy endpoints for the development 
of finite duration therapies for the treatment of chronic HBV 
infection. Drug development considerations for specific subpopulations 
such as patients co-infected with hepatitis D virus or human 
immunodeficiency virus and for pediatric patients with chronic HBV 
infection are also included.
    This guidance finalizes the draft guidance of the same name issued 
on November 2, 2018 (83 FR 55187). FDA provided clarifying edits to the 
final guidance and included additional information after considering 
comments received on the draft guidance. Changes from the draft to the 
final guidance include the following: Considerations and 
recommendations for studies evaluating oligonucleotide-based 
investigational drugs, considerations for drugs developed to modulate 
innate and adaptive immune responses, updates to trial design 
considerations, updates to recommendations for safety monitoring 
(including monitoring for hepatitis flares after treatment 
discontinuation), and updates to efficacy extrapolation from adult to 
pediatric patients.
    This guidance is being issued consistent with FDA's good guidance 
practices regulation (21 CFR 10.115). The guidance represents the 
current thinking of FDA on ``Chronic Hepatitis B Virus Infection: 
Developing Drugs for Treatment.'' 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. Paperwork Reduction Act of 1995

    While this guidance contains no collection of information, it does 
refer to previously approved FDA collections of information. Therefore, 
clearance by the Office of Management and Budget (OMB) under the 
Paperwork Reduction Act of 1995 (PRA) (44 U.S.C. 3501-3521) is not 
required for this guidance. The previously approved collections of 
information are subject to review by OMB under the PRA. The collections 
of information for review of investigational new drug regulations in 21 
CFR part 312 have been approved under OMB control number 0910-0014, and 
the collections of information for review of new drug applications and 
biologic license applications in 21 CFR parts 314 and 601, have been 
approved under OMB control numbers 0910-0001 and 0910-0338, 
respectively. The collection of information regarding accelerated 
approval of serious conditions for drugs and biologics is approved 
under OMB control number 0910-0765. The collection of information 
regarding labeling of prescription drug and biologic products is 
approved under OMB control number 0910-0572.
