SUPPLEMENTARY INFORMATION: 

I. Background

    FDA is announcing the availability of a draft guidance for industry 
entitled ``Developing Targeted Therapies in 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 subsets of patients 
with different underlying molecular alterations 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 caused 
by a range of different molecular alterations, some of which may occur 
at low frequencies, that impact a common protein or pathway involved in 
the disease pathogenesis. In a population of patients with the same 
clinical disease, the heterogeneity in the molecular etiology may 
result in different responses to a particular therapy. However, certain 
targeted therapies may be effective in multiple groups of patients that 
have different underlying molecular alterations. Therefore, FDA is 
providing guidance on the type and quantity of evidence that can 
demonstrate efficacy across molecular subsets within a disease.
    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
 Benefit-risk determination and therapeutic product labeling
 Refining the indicated population after the initial approval
    In addition to comments on the general content of the draft 
guidance, FDA requests input on whether the principles described for 
grouping molecular subsets for clinical trial enrollment should be 
limited to diseases with low-frequency molecular alterations or whether 
they could be broadly applicable to all targeted therapies.
    This draft guidance is being issued consistent with FDA's good 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 ``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.
