The Food and Drug Administration (FDA or Agency) is announcing the availability of a final guidance for industry entitled ``Developing Targeted Therapies in Low-Frequency Molecular Subsets of a Disease.'' This final guidance incorporates public comments to the draft guidance published in the Federal Register of December 18, 2017. The pharmacological effect of a targeted therapy is often related to a particular molecular alteration, and many diseases are caused by a range of different molecular alterations (some of which may be rare). Therefore, a targeted therapy may have differential effects among patients with the same disease who have different molecular alterations. The purpose of this guidance is to describe general approaches to evaluating the benefits and risks of targeted therapeutics within a clinically defined disease where some molecular alterations may occur at low frequencies.

Developing Targeted Therapies in Low-Frequency Molecular Subsets 
of a Disease; Guidance for Industry; Availability

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice of availability.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA or Agency) is announcing 
the availability of a final guidance for industry entitled ``Developing 
Targeted Therapies in Low-Frequency Molecular Subsets of a Disease.'' 
This final guidance incorporates public comments to the draft guidance 
published in the Federal Register of December 18, 2017.
    The pharmacological effect of a targeted therapy is often related 
to a particular molecular alteration, and many diseases are caused by a 
range of different molecular alterations (some of which may be rare). 
Therefore, a targeted therapy may have differential effects among 
patients with the same disease who have different molecular 
alterations. The purpose of this guidance is to describe general 
approaches to evaluating the benefits and risks of targeted 
therapeutics within a clinically defined disease where some molecular 
alterations may occur at low frequencies.

DATES: The announcement of the guidance is published in the Federal 
Register on October 16, 2018.

Friday.
     Confidential Submissions--To submit a comment with 
confidential information that you do not wish to be made publicly 
available, submit your comments only as a written/paper submission. You 
should submit two copies total. One copy will include the information 
you claim to be confidential with a heading or cover note that states 
``THIS DOCUMENT CONTAINS CONFIDENTIAL INFORMATION.'' The Agency will 
review this copy, including the claimed confidential information, in 
its consideration of comments. The second copy, which will have the 
claimed confidential information redacted/blacked out, will be 
available for public viewing and posted on https://www.regulations.gov. 
Submit both copies to the Dockets Management Staff. If you do not wish 
your name and contact information to be made publicly available, you 
can provide this information on the cover sheet and not in the body of 
your comments and you must identify this information as 
``confidential.'' Any information marked as ``confidential'' will not 
be disclosed except in accordance with 21 CFR 10.20 and other 
applicable disclosure law. For more information about FDA's posting of 
comments to public dockets, see 80 FR 56469, September 18, 2015, or

SUPPLEMENTARY INFORMATION: 

I. Background

    FDA is announcing the availability of a guidance for industry 
entitled ``Developing Targeted Therapies in

[[Page 52223]]

Low-Frequency Molecular Subsets of a Disease.'' This guidance is 
intended to assist sponsors in designing drug development programs to 
generate the evidence needed to demonstrate efficacy of a targeted 
therapy across molecular subsets within a disease where some molecular 
alterations may occur at low frequencies.
    In recent years, advances in our understanding of the molecular 
pathology of many diseases have led to the development of targeted 
therapies. Although variability in drug response has long been 
recognized in drug development, targeted therapies present new 
challenges in addressing the heterogeneity in drug response because the 
pharmacological effect of a targeted therapy is often related to a 
particular molecular alteration (e.g., a mutation, gene fusion, 
epigenetic change, etc.). Many clinically defined diseases are 
influenced or caused by a range of different molecular alterations, 
some of which may be rare, that impact a common target protein or 
pathway involved in the disease pathogenesis. This heterogeneity in the 
molecular etiology of a given disease can result in differential 
effects of a targeted therapy among patients with the same disease but 
who have different molecular alterations. Therefore, the type and 
quantity of evidence that is needed to demonstrate efficacy across 
molecular subsets within a disease needs to be clearly specified.
    This guidance addresses the following important topics in 
evaluating the benefits and risks of targeted therapeutics within a 
disease where some molecular alterations may occur at low frequencies:

 Identification of patients for inclusion in clinical trials
 Interpretation of study results and generalizability of 
findings to the study population
 Benefit-risk determination and therapeutic product labeling
 Refining the indicated population after the initial approval

    This final guidance incorporates public comments to the draft 
guidance published in December of 2017 and includes minimal revisions 
for clarity.
    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 ``Developing Targeted Therapies in Low-
Frequency Molecular Subsets of a Disease.'' 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. This guidance is not subject to 
Executive Order 12866.
