SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a draft guidance for industry 
entitled ``Drug-Drug Interaction Assessment for Therapeutic Proteins.'' 
With the continued market growth and increased clinical use of TPs, it 
is important to understand the nature of and the potential for DDIs 
with these products. This guidance supplements the final FDA guidances 
for industry entitled ``In Vitro Drug Interaction Studies--Cytochrome 
P450 Enzyme- and Transporter-Mediated Drug Interactions'' and 
``Clinical Drug Interaction Studies--Cytochrome P450 Enzyme- and 
Transporter-Mediated Drug Interactions'' (January 2020) by providing a 
systematic, risk-based approach to determining the need for DDI studies 
for TPs. This guidance discusses considerations for assessing DDIs for 
TPs, including situations where determining the DDI potential of a TP 
is warranted. The guidance also discusses various types of DDI 
assessments, considerations for study design, and recommendations for 
labeling.
    This draft guidance is being issued consistent with FDA's good 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 The draft guidance, when 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 ``Drug-Drug 
Interaction Assessment for Therapeutic Proteins.'' 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

    This draft guidance refers to previously approved FDA collections 
of information. These collections of information are subject to review 
by the Office of Management and Budget (OMB) under the Paperwork 
Reduction Act of 1995 (44 U.S.C. 3501-3521). The collections of 
information for submissions of investigational new drug applications, 
new drug applications, and biologic license applications in 21 CFR 
parts 312, 314, and 601 have been approved under OMB control numbers 
0910-0014, 0910-0001, and 0910-0338, respectively. In addition, the 
submission of prescription drug labeling under 21 CFR 201.56 and 201.57 
has been approved under OMB control number 0910-0572.

III. Electronic Access

    Persons with access to the internet may obtain the draft guidance 
at either https://www.fda.gov/drugs/guidance-compliance-regulatory-information/guidances-drugs, https://www.fda.gov/vaccines-blood-biologics/guidance-compliance-regulatory-information-biologics/biologics-guidances, or https://www.regulations.gov.
