I. Background

    FDA uses the term ``peptide'' to refer to polymers composed of 40 
or fewer amino acids.\1\ Peptides can be isolated

[[Page 26526]]

from whole animal tissue, or produced in vitro, synthetically or 
through recombinant expression, and often serve as signaling molecules 
for many physiologic functions that are regulated by endogenous 
proteins. Peptides can exhibit distinct combinations of characteristics 
regarding their chemistry, pharmacology, sites of action, 
pharmacokinetic disposition, and pharmacodynamics. Although FDA has 
been regulating peptides for decades, there is a growing appreciation 
for specific considerations for the design and conduct of clinical 
pharmacology studies to assess peptides, such as those designed to 
evaluate the effects of organ impairment or drug interactions.

II. Request for Information and Comments

    Interested persons are invited to provide detailed information and 
comments on certain aspects of evaluating the clinical pharmacology of 
peptides. For all questions, organize any discussion by the type of 
peptide (e.g., isolated from animal source, or produced in vitro, 
synthetically or through recombinant expression) and route of 
administration. Please provide the rationale for your suggestions and 
include supporting data if available. FDA is particularly interested in 
responses to the following overarching questions:
    (1) Under what circumstances should the following assessments be 
warranted or not warranted for peptides?

(a) Evaluating pharmacokinetics-based drug-drug interactions (DDIs)
(b) Evaluating the pharmacokinetics in hepatic impairment
(c) Evaluating immunogenicity and its impact on pharmacokinetics, 
safety, and efficacy
(d) Evaluating QT prolongation

    (2) In circumstances where the assessments above are warranted, 
what types of assessments are suitable and why? What are the study 
design considerations (e.g., in vitro test systems, population, 
analytes, immunogenicity risk assessment, immunogenicity assay 
development and validation) for the types of assessments discussed in 
the following items? Please describe the rationale for any design 
considerations proposed.
    (a) For evaluating pharmacokinetics-based DDIs (e.g., in vitro 
studies, dedicated clinical studies, including cocktail studies, 
population pharmacokinetic analyses), please discuss the advantages, 
challenges, and limitations for these assessments.
    (b) For evaluating pharmacokinetics in hepatic impairment (e.g., 
dedicated clinical studies, population pharmacokinetic analyses), 
please discuss the advantages, challenges, and limitations for these 
assessments.
    (c) For evaluating immunogenicity and its impact on 
pharmacokinetics, safety, and efficacy (e.g., antibodies against the 
active ingredient peptide, peptide-related impurities, or endogenous 
counterpart, if present, neutralizing activity and antibody titers, 
cytokine measurements), please discuss the advantages, challenges, and 
limitations for these assessments.
    (d) For evaluating cardiac electrophysiology (e.g., hERG inhibition 
assay, thorough QT assessment) in nonclinical or clinical studies, 
please discuss the advantages, challenges, and limitations for these 
assessments.
    (3) Are there other clinical pharmacology considerations for 
peptides not covered in the questions above, such as use of 
pharmacodynamic biomarkers and/or pharmacokinetic assessments for dose 
selection? If yes, provide a description and rationale for any proposed 
considerations, as well as approaches, advantages, challenges, and 
limitations for the assessment.
    The public comments collected will help FDA develop recommendations 
for the design and conduct of clinical pharmacology studies important 
to the understanding of the safe and effective use of peptides and 
facilitate the regulatory assessment of such studies.
