Pharmacogenomic Data Submissions
Guidance for Industry1
This draft guidance, when finalized, will represent the current thinking of the Food and Drug Administration (FDA or Agency) on this topic. 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. To discuss an alternative approach, contact the FDA staff responsible for this guidance as listed on the title page.
- INTRODUCTION
This guidance is intended to facilitate progress in the field of pharmacogenomics and the use of
- pharmacogenomic data in drug2 development. This document is intended to clarify the contexts
- in which pharmacogenomic study findings and data must be included in submissions related to
- investigational new drug applications (INDs), new drug applications (NDAs), and biologics
- license applications (BLAs) based on the FDA’s regulations. In addition, this document provides
- recommendations to sponsors and applicants on the format and content of the pharmacogenomic
- data submissions.
23
- For the purposes of this guidance, the term pharmacogenomics is defined as the study of
- variations of DNA and RNA characteristics as related to drug response;3 DNA or RNA
- variations can be germline, somatic, or microbial. Pharmacogenomics does not refer to data
- resulting from proteomic, metabolomic, or other -omic studies, although similar considerations in
- this guidance could be applicable for determining whether to submit findings and data from such
- studies.
30
- In 2005, FDA issued a final guidance for industry, Pharmacogenomic Data Submissions. When
- finalized, this guidance will replace the 2005 guidance.
33
- In general, FDA’s guidance documents do not establish legally enforceable responsibilities.
- Instead, guidances describe the Agency’s current thinking on a topic and should be viewed only
- This guidance has been prepared by the Office of Clinical Pharmacology in the Center for Drug Evaluation and Research in cooperation with the Center for Biologics Evaluation and Research at the Food and Drug Administration as well as the National Center for Toxicological Research.
- For the purposes of this guidance, the terms drug product or drug will be used to refer to human prescription drug and biological products that are regulated as drugs.
- For more information, see the FDA guidance entitled E15: Definitions for Genomic Biomarkers, Pharmacogenomics, Pharmacogenetics, Genomic Data and Sample Coding Categories (April 2008). We update guidances periodically. For the most recent version of a guidance, check the FDA guidance web page at https://www.fda.gov/regulatory-information/search-fda-guidance-documents.

- as recommendations, unless specific regulatory or statutory requirements are cited. The use of
- the word should in Agency guidances means that something is suggested or recommended, but
- not required.

41 II. BACKGROUND
42
- Pharmacogenomic studies have the potential to help identify sources of interindividual
- variability in drug exposure or response (both effectiveness and toxicity), making it possible to
- optimize therapy for individuals. Currently, several pharmacogenomic biomarkers with well-
- accepted mechanistic and clinical significance are being integrated into drug development (e.g.,
- enriched clinical trial designs) and clinical practice.
48
- Sponsors and applicants submitting or holding INDs, NDAs, or BLAs are subject to FDA
- requirements for submitting data to the FDA that are relevant to drug safety and effectiveness.4
- However, the regulations were developed before the advent of widespread animal or human
- genetic testing (e.g., high-throughput DNA sequencing) or gene expression testing and do not
- specifically describe the submission requirements for such data as a separate category.5
54
- This guidance, when final, will constitute the FDA’s current thinking about pharmacogenomic
- study results and the associated data required to be submitted in IND, NDA, or BLA
- submissions, as well as the FDA’s recommendations as to the level of detail and format for
- reporting. Discussions of when and how to submit pharmacogenomic study results and the
- associated data in an investigational device exemption (IDE) application or other device
- submission to the FDA are excluded from the scope of this document.6 This guidance is intended
- to facilitate the generation and use of pharmacogenomic data during drug development. The
- policies outlined in this guidance are intended to advance the field in a manner that will benefit
- both drug development programs and public health.
64
65
- III. SUBMISSION POLICY
- The FDA’s regulations establish requirements for the submission of information in INDs, NDAs,
- and BLAs.7 Consistent with these regulations, the sections below summarize the contexts in
- which pharmacogenomic study results and data must be reported in IND, NDA, and BLA
71 submissions.8
- 21 CFR parts 312, 314, and 601 (including 21 CFR 312.22, 312.23, 312.31, 312.33, 314.50, 314.81, 601.2, and 601.12).
- 21 CFR parts 312, 314, and 601.
- 21 CFR part 812.
- 21 CFR parts 312, 314, and 601.
- 21 CFR parts 312, 314, and 601 (including 21 CFR 312.22, 312.23, 312.31, 312.33, 314.50, 314.81, 601.2, and 601.12).

- Table 1 also summarizes the FDA’s recommendations on the amount and level of detail to report
- for each context in which pharmacogenomic study results and data are reported to the FDA. The
- amount and level of detail to report to the FDA should vary depending on the context of how the
- genomic biomarkers are utilized and the potential risks associated with the biomarker. For
- example, data related to exploratory safety studies should be supplied in a brief synopsis,
- whereas data supporting statements in FDA labeling should be supplied in submission of subject-
- level data from clinical trials. Genomic data that fit multiple contexts should be submitted at the
- more detailed reporting level. For example, genomic biomarker studies that are related to
- pharmacokinetics (e.g., drug metabolizing enzyme gene variants) are recommended to be
- submitted as a synopsis. However, if those same genomic data are also the basis for patient
- dosing, subject-level data, and a full report rather than only a synopsis should be submitted.
- More detailed reports and data can be submitted where synopses are recommended. Furthermore,
- the FDA may request additional data (e.g., detailed reports, subject level data) as needed for the
- review of IND submissions as well as NDAs or BLAs as outlined in 21 CFR parts 312, 314, and
- 601.
88
- Sections III.A and III.B provide additional information regarding the submission of
- pharmacogenomic data under IND regulations and NDA and BLA regulations, respectively. For
- additional information on data submission and report formats, see section IV.

- order to comply with the regulation’s requirements.9 The contexts in which
- pharmacogenomic data must be submitted and the FDA’s recommendations for the extent
- of and mechanism for reporting are as follows:
100 | o Pharmacogenomic study findings supporting the use of a genomic biomarker in | |
101 | ||
102 | the design, conduct, or analysis10 of planned clinical trials are required to be | |
103 | reported to the FDA with detailed information about such findings.11 Detailed | |
104 | reports should be submitted in this context to facilitate the review of the | |
105 | biomarker’s clinical validity and ensure that trials making use of the biomarker | |
106 | are expected to meet stated objectives.12 Detailed reports should be submitted in | |
107 | the IND under the Previous Human Experience section, in meeting packages, or | |
108 | in clinical study protocols/reports, as appropriate. | |
109 | o Pharmacogenomic study results from completed clinical trials where the | |
110 | ||
111 | biomarker was integral to the design, conduct, or analysis “[are] pertinent to the | |
112 | understanding of the drug’s actions” and must be described in Annual Reports.13 | |
113 | o Pharmacogenomic study findings derived from animal or in vitro studies must be | |
114 | ||
115 | submitted when intended primarily to support the safety of the proposed clinical | |
116 | investigation.14 | |
117 | o The FDA recognizes that many pharmacogenomic studies are exploratory and | |
118 | ||
119 | might not have been replicated. However, pharmacogenomic studies that identify | |
120 | significant predictors of treatment response must be reported in Annual Reports | |
121 | because they pertain to understanding the drug’s actions.15 Significant predictors | |
122 | of treatment response include substantial differences in treatment response across | |
123 | biomarker-defined subgroups or statistically significant relationships between the | |
124 | biomarker and primary study endpoints in the context of the study. In addition, all | |
125 | pharmacogenomic studies generating data related to the effect of variation in the | |
126 | drug target or other genes related to the mechanism of action on efficacy or safety | |
127 | endpoints, as well as pharmacodynamic studies that make use of genomic | |
128 | biomarkers as an endpoint (e.g., gene expression), must also be reported in |
- See 312.23, 312.32, 312.33.
- In effect, the genomic biomarker is used for the inclusion or exclusion of study subjects, treatment allocation (e.g., stratified randomization), subgroup hypothesis testing, altered dosing, or monitoring.

129 | Annual Reports because they pertain to understanding the drug’s actions.16 These | |
130 | pharmacogenomic studies should be reported as synopses and should also be | |
131 | included in meeting packages and/or in clinical study protocols/reports, as | |
132 | appropriate. A study could be an analysis of an individual study or a pooled | |
133 | analysis of multiple trials. Statistical significance should be considered in the | |
134 | context of applying conventional multiplicity corrections. | |
135 | o Pharmacogenomic study findings related to safety endpoints must be reported in | |
136 | ||
137 | IND Safety Reports because they pertain to the drug’s safety17 or in Annual | |
138 | Reports because they pertain to understanding the drug’s actions.18 These | |
139 | pharmacogenomic studies should be reported as synopses and should also be | |
140 | included in meeting packages and/or in clinical study protocols/reports, as | |
141 | appropriate. Pharmacogenomic findings that identify predictors of adverse events | |
142 | which may pose significant risks to study subjects, or otherwise indicate a | |
143 | significant risk, must be submitted in an IND Safety Report.19 | |
144 | o Other studies related to safety endpoints or that use gene expression as an | |
145 | ||
146 | endpoint to identify safety signals but do not identify any significant relationships | |
147 | must be described in Annual Reports.20 Pertinent negative findings must be | |
148 | explicitly reported (e.g., absence of HLA involvement in immune-related adverse | |
149 | events, or absence ADME-related effects where an exposure-response | |
150 | relationship for safety has been documented).21 | |
151 | o Study findings related to pharmacokinetics must be reported in Annual Reports | |
152 | ||
153 | because they pertain to the drug’s bioavailability and/or dose-response | |
154 | relationship.22 This can include pharmacokinetic studies where enrollment is | |
155 | prospectively based on drug metabolizing enzyme or transporter genotype, or | |
156 | retrospective studies on efficacy, safety, or pharmacokinetic endpoints (e.g., drug | |
157 | metabolizing enzyme and transporter panels). These studies should be reported as | |
158 | synopses and should also be included in meeting packages and/or in clinical study | |
159 | protocols/reports, as appropriate. | |

- pharmacogenomic associations with pharmacokinetics, effectiveness, or safety in
- Investigator Brochures.23
164
- • Pharmacogenomic studies that are not required to be submitted under 21 CFR part 312
- can be voluntarily reported.
167
- • 21 CFR 312.23(a)(11) states that a sponsor shall submit “[i]f requested by FDA, any
- other relevant information needed for review of the application.” Therefore, during the
- IND review, the FDA might request additional pharmacogenomic information it
- considers relevant.
172
- B.Submission of Pharmacogenomic Reports and Data Under NDA and BLA
174 | Regulations |
175 |
- • 21 CFR 314.50 outlines the NDA submission requirements. As the introduction to 21
- CFR 314.50 states, “[t]he NDA is required to contain reports of all investigations of the
- drug product sponsored by the applicant, and all other information about the drug
- pertinent to an evaluation of the NDA that is received or otherwise obtained by the
- applicant from any source.” Information that is pertinent to an evaluation of the
- application includes information related to each controlled clinical study pertinent to a
- proposed use of the drug, a description and analysis of “any other data or information
- relevant to an evaluation of the safety and effectiveness of the drug product,” and “[a]
- summary and updates of safety information.”24 The pharmacogenomic studies required to
- be submitted to the FDA for an IND are generally relevant to the FDA’s evaluation of the
- safety and effectiveness of a drug product. Therefore, to comply with these regulations,
- sponsors must provide reports of certain pharmacogenomic studies in their NDAs as
- outlined in Table 1.25 Table 1 also specifies the recommended reporting level for each
- type of pharmacogenomic study reported in NDAs. Sponsors can discuss submission of
- pharmacogenomic reports and data in NDA submissions at pre-NDA meetings.
191
- • 21 CFR 601.2 generally outlines the BLA submission requirements. 21 CFR 601.2 states
- that the BLA manufacturer “shall submit data derived from nonclinical laboratory and
- clinical studies which demonstrate that the manufactured product meets prescribed
- requirements of safety, purity, and potency…” The pharmacogenomic studies required to
- be submitted to the FDA for an IND are generally relevant to the FDA’s evaluation of the
- safety, purity, and potency of a biological product. Therefore, like NDA sponsors, BLA
- sponsors must provide reports of certain pharmacogenomic studies in their BLAs as
- outlined in Table 1.26 Table 1 also specifies the recommended reporting level for each
- 21 CFR 312.23(a)(5)(iii) and 21 CFR 312.23(a)(5)(iv).
- 21 CFR 314.50(d)(5)(iv) and (vi); 21 CFR 314.50(d)(5)(vi) also identifies the specific types of information that constitute the “summary and updates of safety information.”

- type of pharmacogenomic study reported in BLAs. Sponsors can discuss submission of
- pharmacogenomic reports and data in BLA submissions at pre-BLA meetings.
202
- • In addition, if a sponsor intends for pharmacogenomic study data to be used in the drug
- labeling or as part of the scientific database being relied upon to support approval, then
- data must be submitted from such studies to the NDA or BLA.27 Such data should be
- submitted as subject-level data in a detailed report. This includes data pertaining to
- pharmacogenomic biomarkers that inform labeling, because the data pertain to selecting
- patients for clinical trials (whether enrollment is limited to or stratified by the
- biomarkers), determining dosing and administration, or informing drug-drug interactions
- (or lack thereof). Also, information not tied to specific clinical recommendations must be
- submitted if it relates to any narrative about the drug’s pharmacokinetic disposition or
- clinical trial populations in labeling.28
213
- • 21 CFR 314.81(b)(2) and 601.12 outline the requirements for submitting to a previously
- approved NDA or BLA, new scientific information that might affect the safety,
- effectiveness, or labeling of a drug. Pharmacogenomic studies outlined in Table 1, and as
- further described in section III.A, must be submitted in Annual Reports29 and should also
- be submitted, as appropriate, in meeting packages and/or clinical study protocols/reports.
219
- • Pharmacogenomic studies that are exploratory in nature, such as initial studies to
- discover predictors of drug response, pharmacoepidemiologic, or observational studies,
- and that are not described in Table 1 or sections III.A or III.B, are not required to be
- reported.
