Background FDA is announcing the availability of a draft guidance for industry entitled ‘‘Clinical Lactation Studies—Study Design, Data Analysis, and Recommendations for Labeling.’’ This guidance is intended to provide recommendations to sponsors and investigators on how to design, conduct, and assess studies investigating the influence of lactation on maternal pharmacokinetics (PK), and where appropriate, the pharmacodynamics of drugs or biologic products, the extent of drug transfer into breast milk, and the effects of drugs on milk production and composition. Clinical lactation studies are usually not conducted during the development of most products and lactating women are actively excluded from trials. Consequently, at the time of a drug’s initial marketing, there are seldom meaningful human data on the appropriate dosage and frequency of administration during lactation. Even after years of marketing, data in product labels regarding lactation rarely provide more information for appropriate prescribing in lactation than what was available at the time of initial marketing. The information in this guidance is intended to promote an increase in the amount of useful data concerning how drug kinetics are affected by lactation, the extent of drug transfer into breast milk, and the effects of drugs on milk production and composition. Topics covered include study design, data analysis, labeling, and considerations for future research. The agency recommends using this guidance in conjunction with other pharmacological and clinical literature on the design, PO 00000 Frm 00086 Fmt 4703 Sfmt 4703 6697 conduct, and interpretation of PK studies. Because the conduct of studies in lactating women and their breast-fed infants requires specialized knowledge in a variety of areas, investigators designing such studies are encouraged to obtain advice from experts in fields including obstetrics, pediatrics, pharmacology, clinical pharmacology, pharmacometrics, statistics, and other applicable disciplines. This draft guidance is being issued consistent with FDA’s good guidance practices regulation (21 CFR 10.115). The draft guidance, when finalized, will represent the agency’s current thinking on this topic. 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. II. Comments Interested persons may submit to the Division of Dockets Management (see ADDRESSES) written or electronic comments on the draft guidance.

SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a draft guidance for industry 
entitled ``Clinical Lactation Studies--Study Design, Data Analysis, and 
Recommendations for Labeling.'' This guidance is intended to provide 
recommendations to sponsors and investigators on how to design, 
conduct, and assess studies investigating the influence of lactation on 
maternal pharmacokinetics (PK), and where appropriate, the 
pharmacodynamics of drugs or biologic products, the extent of drug 
transfer into breast milk, and the effects of drugs on milk production 
and composition. Clinical lactation studies are usually not conducted 
during the development of most products and lactating women are 
actively excluded from trials. Consequently, at the time of a drug's 
initial marketing, there are seldom meaningful human data on the 
appropriate dosage and frequency of administration during lactation. 
Even after years of marketing, data in product labels regarding 
lactation rarely provide more information for appropriate prescribing 
in lactation than what was available at the time of initial marketing.
    The information in this guidance is intended to promote an increase 
in the amount of useful data concerning how drug kinetics are affected 
by lactation, the extent of drug transfer into breast milk, and the 
effects of drugs on milk production and composition. Topics covered 
include study design, data analysis, labeling, and considerations for 
future research. The agency recommends using this guidance in 
conjunction with other pharmacological and clinical literature on the 
design, conduct, and interpretation of PK studies. Because the conduct 
of studies in lactating women and their breast-fed infants requires 
specialized knowledge in a variety of areas, investigators designing 
such studies are encouraged to obtain advice from experts in fields 
including obstetrics, pediatrics, pharmacology, clinical pharmacology, 
pharmacometrics, statistics, and other applicable disciplines.
    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 this topic. 
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.

II. Comments

    Interested persons may submit to the Division of Dockets Management 
(see ADDRESSES) written or electronic comments on the draft guidance. 
Submit a single copy of electronic comments or two paper copies of any 
mailed comments, except that individuals may submit one paper copy. 
Comments are to be identified with the docket number found in brackets 
in the heading of this document. The draft guidance and received 
comments are available for public examination in the Division of 
Dockets Management between 9 a.m. and 4 p.m., Monday through Friday.
