It does not establish any rights for any person and is not 8 binding on FDA or the public. You can use an alternative approach if it satisfies the requirements of the 9 applicable statutes and regulations. To discuss an alternative approach, contact the FDA staff responsible 10 for this guidance as listed on the title page. 11 12 13 14 I. INTRODUCTION 15 16 This guidance is intended to assist applicants of human prescription drug and biological 17 products2 in determining the appropriate placement and content of geriatric information in 18 labeling as described in the regulations for the content and format of labeling for human 19 prescription drug and biological products.3,4 20 21 The goal of this guidance is to provide recommendations to help ensure that appropriate 22 information on the use of prescription drugs in geriatric patients is consistently placed in the 23 proper sections and subsections within labeling so that the information is clear and accessible to 24 health care practitioners and includes content that guides the safe and effective use in geriatric 25 patients. 26 27 This guidance, which replaces the withdrawn guidance for industry Content and Format for 28 Geriatric Labeling (October 2001), provides additional examples of geriatric use statements in 29 labeling and examples of when the labeling regulations authorize the FDA to permit applicants to 30 omit or revise specific information otherwise required in the Geriatric Use subsection. 31 32 In general, FDA’s guidance documents do not establish legally enforceable responsibilities. 33 Instead, guidances describe the Agency’s current thinking on a topic and should be viewed only 34 as recommendations, unless specific regulatory or statutory requirements are cited. The use of 35 1 This guidance has been prepared by the Labeling Policy Team in the Center for Drug Evaluation and Research in cooperation with the Center for Biologics Evaluation and Research at the Food and Drug Administration. 2 For the purposes of this guidance, references to drugs and drug and biological products include drugs approved under section 505 of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 355) and biological products licensed under section 351 of the Public Health Service Act (42 U.S.C. 262) that are regulated as drugs. 3 See 21 CFR 201.56(d) and 21 CFR 201.57. 4 This guidance does not pertain to labeling for nonprescription drugs.

BACKGROUND 40 41 A. Geriatric Initiatives 42 43 1. Geriatric Clinical Data Initiatives 44 45 In the 1980s, the FDA began several initiatives to increase the quantity and quality of 46 information about the use of drugs in geriatric patients (defined as patients 65 years of age and 47 older) so that health care practitioners would have enough information for the safe and effective 48 use of drugs in geriatric patients. For example, the FDA encourages a thorough evaluation of the 49 effectiveness and safety of drugs in geriatric patients and recommends examination of age- 50 related differences in effectiveness, dose response, and safety.5 In 1998, the FDA required new 51 drug application (NDA) holders6 and, subsequently, recommended that biologics license 52 application (BLA) holders7 present in their applications effectiveness and safety data based on 53 age. In 2012, in an International Conference on Harmonisation (ICH) guidance for industry, the 54 FDA reaffirmed the importance of obtaining geriatric data, across the entire full age range of the 55 geriatric population because of the likelihood of comorbidities and the increasing number of 56 geriatric patients in the United States.8 The guidance also noted ways in which geriatric patients 57 (especially patients 75 years of age and older) may respond differently to drug therapy than 58 younger adult patients.9 59 60 In 2012, the Food and Drug Administration Safety and Innovation Act (FDASIA) directed the 61 FDA to report on the inclusion of demographic subgroups (including age subgroups) in clinical 62 5 See the guidance for industry Guideline for the Study of Drugs Likely to Be Used in the Elderly (November 1989) and the International Conference on Harmonisation guidance for industry E7 Studies in Support of Special Populations: Geriatrics (August 1994). We update guidances periodically. To make sure you have the most recent version of a guidance, check the FDA guidance web page at https://www.fda.gov/regulatory-information/search-fda- guidance-documents. 6 See the preamble of the demographic rule (21 CFR 314.50(d)(5); 63 FR 6854) published February 11, 1998. In addition to age, NDA holders are required to present effectiveness and safety data in other important demographic groups in their NDAs. 7 See the guidance for industry and FDA staff Collection of Race and Ethnicity Data in Clinical Trials (October 2016). In addition to age, the FDA recommends that BLA holders present effectiveness and safety data in other important demographic groups in their BLAs. 8 See the ICH guidance for industry E7 Studies in Support of Special Populations: Geriatrics: Questions and Answers (February 2012). 9 Ibid.

Geriatric Labeling Initiatives 66 67 Until the late 1990s, the majority of drug labeling contained minimal or no geriatric use 68 information to guide safe and effective use in the geriatric population. In 1997, the FDA issued a 69 final rule creating a Geriatric Use subsection of labeling to promote the consistent inclusion of 70 all relevant geriatric information in labeling.11 This subsection is intended to provide 71 information on possible differences in the safety, effectiveness, pharmacodynamics, and/or 72 pharmacokinetics between geriatric and younger adult patients given differences in responses, 73 drug elimination, comorbidities, organ function (e.g., renal function), consequences of adverse 74 reactions, and concomitant therapy (e.g., higher risk of drug interactions because of 75 polypharmacy). 76 77 In 2001, the FDA issued the now-withdrawn guidance for industry Content and Format for 78 Geriatric Labeling, which provided recommendations for the Geriatric Use subsection in the 79 PRECAUTIONS section. In 2006, the FDA issued the final rule “Requirements on Content and 80 Format of Labeling for Human Prescription Drug and Biological Products” (commonly referred 81 to as the physician labeling rule (PLR)), which relocated the Geriatric Use subsection from the 82 PRECAUTIONS section in old (non-PLR) format labeling to the USE IN SPECIFIC 83 POPULATIONS section for labeling required to be in PLR format.12 84 85 B. Geriatric Population in Labeling 86 87 In general, for prescription drug labeling, the adult population is defined as patients 17 years of 88 age and older, and the geriatric population is defined as patients 65 years of age and older.13 89 Therefore, information in labeling that is pertinent to the adult population is typically also 90 pertinent to the geriatric population (e.g., indications approved in adults include geriatric 91 patients).14 92 93 10 See section 907 of FDASIA. 11 See the preamble of the final rule, “Specific Requirements on Content and Format of Labeling for Human Prescription Drugs; Addition of ‘Geriatric Use’ Subsection in the Labeling,” (21 CFR 201; 62 FR 45313) published August 27, 1997, section II.A. 12 See the preamble of the final rule, “Requirements on Content and Format of Labeling for Human Prescription Drug and Biological Products,” (21 CFR parts 201, 314, and 601; 71 FR 3922) published January 24, 2006. 13 21 CFR 201.57(c)(9)(iv)(A) and 21 CFR 201.57(c)(9)(v)(A). 14 See the draft guidance for industry Indications and Usage Section of Labeling for Human Prescription Drug and Biological Products — Content and Format (July 2018). When final, this guidance will represent the FDA’s current thinking on this topic.
Contains Nonbinding Recommendations Draft – Not for Implementation 4 The information in the Geriatric Use subsection must pertain to the use of the drug in patients 65 94 years of age and older, unless otherwise noted.15 Patients 65 years of age and older are not a 95 homogeneous group (e.g., differences in organ function, comorbidities, concomitant drugs, and 96 drug distribution and elimination). Applicants should include information on additional geriatric 97 age subgroups in the labeling if important differences exist in responses in these subgroups.16 98 Such subgroups should be further defined in the labeling as appropriate (e.g., 65-74 years of age; 99 75-84 years of age; and 85 years of age and older).17 In some cases, geriatric age might be 100 expressed as a continuous function of age.18 101 102 103 III. OVERVIEW OF GERIATRIC USE INFORMATION IN HUMAN 104 PRESCRIPTION DRUG AND BIOLOGICAL PRODUCT LABELING 105 106 In general, applicants must summarize certain geriatric use information in the Geriatric Use 107 subsection19 and, when appropriate, must cross-reference the appropriate section(s) or 108 subsection(s) of labeling that provide more detailed geriatric use information.20 Certain geriatric 109 use information must be included based on the type of information being conveyed,21 which can 110 be characterized as follows: 111 112 15 21 CFR 201.57(c)(9)(v)(A). See also the preamble of the final rule, “Specific Requirements on Content and Format of Labeling for Human Prescription Drugs; Addition of ‘Geriatric Use’ Subsection in the Labeling,” (21 CFR 201; 62 FR 45313, 45316) published August 27, 1997, stating that the Agency “does not consider 65 years of age to be an absolute” age cut-off to define geriatric patients in labeling. For some labeling, it may be more appropriate to choose a different age cut-off to define geriatric patients. 16 See the preamble of the final rule, “Specific Requirements on Content and Format of Labeling for Human Prescription Drugs; Addition of ‘Geriatric Use’ Subsection in the Labeling,” (21 CFR 201; 62 FR 45313, 45316) published August 27, 1997. 17 The FDA recommends that the age distribution in the clinical development program be representative of the target population, and that applications should assess the consistency of the treatment effect and safety profile in geriatric subpopulations (e.g., 65–74 years of age, 75–84 years of age, and 85 years of age and older) and younger adults. See the guidance for industry E7 Studies in Support of Special Populations: Geriatrics: Questions and Answers. 18 See the preamble of the final rule, “Specific Requirements on Content and Format of Labeling for Human Prescription Drugs; Addition of ‘Geriatric Use’ Subsection in the Labeling,” (21 CFR 201; 62 FR 45313, 45316) published August 27, 1997. 19 See 21 CFR 201.57(c)(9)(v). The FDA may permit omission of required statement(s) in the Geriatric Use subsection if the FDA determines that no statement described in 21 CFR 201.57(c)(9)(v)(A) to (E) is appropriate or relevant to the drug’s labeling; additionally, the FDA may permit an alternative appropriate and accurate statement(s) (21 CFR 201.57(c)(9)(v)(F)). 20 21 CFR 201.57(c)(9)(v)(B)(3) and 21 CFR 201.57(c)(9)(v)(D). Additional cross-references from the Geriatric Use subsection to other section(s)/subsection(s) are recommended when there is more detailed geriatric use information in those other section(s)/subsection(s). See the guidance for industry Labeling for Human Prescription Drug and Biological Products — Implementing the PLR Content and Format Requirements (February 2013). 21 See 21 CFR 201.57(c)(9)(v).

Including Information in the Geriatric Use Subsection of Labeling (Scenarios 142 1.1, 1.2, and 1.3) 143 144 The Geriatric Use subsection must include certain information pertinent to the safe and effective 145 use of the drug in geriatric patients for all indications approved for use in adult patients 146 (including geriatric patients).26 147 148 22 21 CFR 201.57(c)(9)(v)(B)(2). 23 21 CFR 201.57(c)(9)(v)(B)(3). 24 21 CFR 201.57(c)(9)(v)(B)(1). 25 21 CFR 201.57(c)(9)(v)(A). 26 21 CFR 201.57(c)(9)(v)(B).
Contains Nonbinding Recommendations Draft – Not for Implementation 6 Information in this subsection is typically derived from results from controlled clinical studies 149 submitted in the application or supplement(s) that are relevant to the use of the drug in geriatric 150 patients. However, sometimes information in this subsection is obtained from “other reported 151 clinical experience”27 such as, but not limited to, well-documented studies obtained from a 152 literature search, clinically relevant information from registries, other epidemiological or 153 surveillance studies, case series studies, and adverse event reports.28 154 155 Under scenario 1.1, the Geriatric Use subsection must include the percentage of patients 65 156 years of age and older and the percentage of patients 75 years of age and older (or the total 157 number of patients 65 years of age and older and the total number of patients 75 years of age and 158 older) in the clinical studies of the drug.29 Under this scenario, to provide more information to 159 health care practitioners about geriatric exposure, the FDA recommends that this subsection 160 present both the number and percentage of drug-exposed patients 65 years of age and older, and 161 the number and percentage of drug-exposed patients 75 years of age and older in a defined group 162 of clinical studies (typically the clinical studies that supported the approval of the drug in adult 163 patients, including geriatric patients). Under scenario 1.1, alternative age cutoff point(s) within 164 the geriatric population may be permitted to describe drug exposure, if the FDA determines that 165 such age cutoff point(s) are accurate and appropriate.30 166 167 Under scenarios 1.2 and 1.3, the FDA recommends including geriatric exposure information in 168 the Geriatric Use subsection. Specifically, we recommend that this subsection provide both the 169 number and percentage of drug-exposed geriatric patients in a defined group of clinical studies 170 (typically the clinical studies that supported the approval of the drug in adult patients, including 171 geriatric patients). Different age cutoff points within the geriatric population can be selected to 172 describe drug exposure, depending on the database (see section II.B., Geriatric Population in 173 Labeling, in this guidance). 174 175 Under scenarios 1.1, 1.2, and 1.3, the Geriatric Use subsection can also include information on 176 the total number of geriatric patients in the clinical studies (e.g., including drug-treated patients 177 and control-treated patients). Under these scenarios, we recommend that this subsection cross- 178 reference to other sections of labeling that contain additional details about the studies used to 179 determine the geriatric exposure (e.g., the CLINICAL STUDIES section). 180 181 In general, geriatric exposure information should be placed at the beginning of the Geriatric Use 182 subsection. However, information on specific risks or safety concerns associated with the use of 183 the drug in geriatric patients and/or recommendations on specific monitoring in geriatric patients 184 may appear before the drug exposure information. 185 186 27 21 CFR 201.57(c)(9)(v)(B)(1), (2), and (3). 28 See the preamble of the final rule, “Specific Requirements on Content and Format of Labeling for Human Prescription Drugs; Addition of ‘Geriatric Use’ Subsection in the Labeling,” (21 CFR 201; 62 FR 45313) published August 27, 1997. 29 21 CFR 201.57(c)(9)(v)(B)(2). 30 21 CFR 201.57(c)(9)(v)(F).
Contains Nonbinding Recommendations Draft – Not for Implementation 7 The following examples represent options for summarizing geriatric exposure information under 187 scenarios 1.1, 1.2, and/or 1.3; alternative language can be proposed. 188 189 • Example 1: 190 191 “There were n patients 65 years of age and older in the clinical studies for Disease A [see 192 Clinical Studies (14)]. Of the total number of DRUG X-treated patients in these studies, 193 n (y%) were 65 years of age and older, while n (z%) were 75 years of age and older.” 194 195 • Example 2: 196 197 “Of the total number of DRUG X-treated patients in clinical studies for Disease A, n 198 (y%) were 65 to 74 years of age, and n (z%) were 75 years of age and older [see Clinical 199 Studies (14)].” 200 201 • Example 3: 202 203 “There were n patients 65 years of age and older in the clinical studies for Disease A, 204 Disease B, and Disease C [see Clinical Studies (14.1, 14.2, 14.3)]. Of the total number 205 of DRUG X-treated patients in these studies, n (x%) were 65 to 74 years of age, n (y%) 206 were 75 to 84 years of age, and n (z%) were 85 years of age and older.” 207 208 1. When Information Is Sufficient to Detect Differences in Safety and/or 209 Effectiveness Between Geriatric and Younger Adult Patients — Geriatric Use 210 Subsection (Scenarios 1.1 and 1.2) 211 212 Factors that can affect whether there is sufficient information to detect differences in safety or 213 effectiveness between geriatric and younger adult patients include the numbers of geriatric 214 patients treated with the drug and control compared with the numbers of younger adult patients 215 treated with the drug and control, the age distribution within the geriatric and younger adult 216 subpopulations, the specific safety or effectiveness outcomes of interest, the magnitudes of 217 differences in effects, and the variability in the outcomes. We recommend applicants contact the 218 Agency if they have questions about whether there is sufficient information to detect differences 219 in safety or effectiveness between geriatric and younger adult patients. 220 221 In general, integrated analyses of geriatric data from multiple studies can help increase the 222 precision of safety and effectiveness evaluations and provide a more clinically useful 223 representation of a drug’s benefit-risk profile in geriatric patients. Determination of whether and 224 how to include such integrated analyses in labeling should incorporate considerations about any 225 differences in design or conduct between studies. The method for integration should 226 appropriately account for the effect of differences in randomization ratios, patient populations, 227
Contains Nonbinding Recommendations Draft – Not for Implementation 8 and other factors across studies and use statistically appropriate methods for integrating data 228 from multiple studies to minimize bias.31 229 230 a. No observed differences in safety and/or effectiveness in geriatric patients 231 compared to younger adult patients (scenario 1.1) 232 233 If clinical studies included enough geriatric patients to make it likely that differences in safety or 234 effectiveness between geriatric and younger adult patients would have been detected, but no such 235 differences (in safety or effectiveness) were observed, and other reported clinical experience has 236 not identified such differences, the Geriatric Use subsection must contain the following 237 statement after information about the percentage (or number) of geriatric patients (see section 238 IV.A., Including Information in the Geriatric Use Subsection of Labeling (Scenarios 1.1, 1.2, and 239 1.3), of this gudiance):32 240 241 “No overall differences in safety or effectiveness were observed between these subjects and 242 younger subjects, and other reported clinical experience has not identified differences in 243 responses between the elderly and younger patients, but greater sensitivity of some older 244 individuals cannot be ruled out.” 245 246 An alternative statement may be permitted, if the FDA determines that such statement is accurate 247 and appropriate.33 Permissible changes may include, but are not limited to, the following: 248 249 • Using the term patients instead of subjects 250 251 • Using the term younger adult patients instead of younger subjects if safety and 252 effectiveness comparisons were made between geriatric and younger adult patients (not 253 pediatric patients) 254 255 • Removing the phrase “other reported clinical experience has not identified differences in 256 responses between the elderly and younger patients” if there were no other clinical 257 experience in geriatric patients (beyond the clinical study data submitted to support drug 258 approval) because, for example, the drug is a new molecular entity that has never been 259 marketed in any country 260 261 • Removing the phrase “but greater sensitivity of some older individuals cannot be ruled 262 out” if this statement is inaccurate and/or clearly inapplicable for the drug34 263 264 31 See the draft guidance for industry Meta-Analyses of Randomized Controlled Clinical Trials to Evaluate the Safety of Human Drugs or Biological Products (November 2018). When final, this guidance will represent the FDA’s current thinking on this topic. 32 21 CFR 201.57(c)(9)(v)(B)(2). 33 21 CFR 201.57(c)(9)(v)(F). 34 21 CFR 201.56(a)(2) and 21 CFR 201.56(d)(4).
Contains Nonbinding Recommendations Draft – Not for Implementation 9 Such changes would result in an alternative statement such as the following: 265 266 “No overall differences in safety or effectiveness of DRUG X have been observed between 267 patients 65 years of age and older and younger adult patients.” 268 269 For most topical ophthalmic drugs there have been no observed differences in safety or 270 effectiveness between geriatric and younger adult patients in clinical studies. The systemic 271 absorption of topical ophthalmic drugs is usually minimal, and consequently, systemic effects are 272 unlikely and have been observed infrequently. Thus, when clinical differences between geriatric 273 and younger adult patients have not been demonstrated, applicants of topical ophthalmic drugs 274 may also use the alternative statement above. 275 276 b. Differences in safety and/or effectiveness in geriatric patients compared to 277 younger adult patients (scenario 1.2) 278 279 The Geriatric Use subsection must contain a summary of observed differences or specific 280 monitoring or dosage requirements in certain situations.35 These situations occur when clinical 281 studies and/or other reported clinical experience indicate that the use of the drug in geriatric 282 patients, compared to its use in younger adult patients, is associated with differences in safety or 283 effectiveness or requires specific monitoring or different recommended dosage in geriatric 284 patients. For example, if geriatric patients experienced unique adverse reactions, adverse 285 reactions occurred at a greater frequency or severity in geriatric patients than in younger adult 286 patients, or there was reduced effectiveness in geriatric patients, this information must appear in 287 the Geriatric Use subsection.36 As appropriate, this information must also be included in other 288 sections (e.g., DOSAGE AND ADMINISTRATION, CONTRAINDICATIONS, WARNINGS 289 AND PRECAUTIONS, ADVERSE REACTIONS, CLINICAL STUDIES).37 For example: 290 291 “The overall response rates in DRUG X-treated adult patients younger than 65 years of age, 292 65 years of age to younger than 75 years of age, and 75 years of age and older were 25%, 293 20%, and 15%, respectively. In comparison, the overall response rate for placebo-treated 294 patients in each of these subgroups was 10%. 295 296 In patients 65 years of age and older, consider premedication with drug 1, drug 2, and drug 3 297 before DRUG X use [see Dosage and Administration (2.x)]. In DRUG X-treated patients, 298 the incidence of ≥ Grade 3 gastrointestinal (GI) adverse reactions (i.e., nausea and vomiting) 299 was 10%, 35%, and 40% in adult patients younger than 65 years of age, 65 years of age to 300 younger than 75 years of age, and 75 years of age and older, respectively [see Adverse 301 Reactions (6.1)]. In comparison, in placebo-treated patients, ≥ Grade 3 GI adverse reactions 302 (i.e., nausea and vomiting) occurred in 1–3% of patients in the three subpopulations.” 303 304 35 See 21 CFR 201.57(c)(9)(v)(B)(3). 36 Ibid. 37 Ibid.

When Information Is Insufficient to Detect Differences in Safety and/or 305 Effectiveness Between Geriatric and Younger Adult Patients — Geriatric Use 306 Subsection (Scenario 1.3) 307 308 If clinical studies did not include sufficient numbers of geriatric patients to determine whether 309 geriatric patients respond differently than younger adult patients, and other reported clinical 310 experience has not identified such differences, the Geriatric Use subsection must include the 311 following statement (with respect to format, the FDA recommends this statement appear after the 312 geriatric exposure information; see section IV.A., Including Information in the Geriatric Use 313 Subsection of Labeling (Scenarios 1.1, 1.2, and 1.3), in this guidance):38 314 315 “Clinical studies of (name of drug) did not include sufficient numbers of subjects aged 65 316 and over to determine whether they respond differently from younger subjects. Other 317 reported clinical experience has not identified differences in responses between the elderly 318 and younger patients. In general, dose selection for an elderly patient should be cautious, 319 usually starting at the low end of the dosing range, reflecting the greater frequency of 320 decreased hepatic, renal, or cardiac function and of concomitant disease or other drug 321 therapy.”39 322 323 An alternative statement may be permitted, if the FDA determines that such statement is accurate 324 and appropriate.40 In addition to the permissible changes noted for scenario 1.1, additional 325 changes may include, but are not limited to, the following: 326 327 • Defining the geriatric age group in the labeling 328 329 • Removing the following sentence if the drug has only one recommended starting dosage: 330 331 “In general, dose selection for an elderly patient should be cautious, usually starting at the 332 low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, 333 or cardiac function and of concomitant disease or other drug therapy.” 334 335 Such changes would result in an alternative statement such as the following: 336 337 “Clinical studies of DRUG X did not include sufficient numbers of patients 65 years of age 338 and older to determine whether they respond differently from younger adult patients.” 339 340 When a drug is approved for adult patients (including geriatric patients) but there is limited or no 341 experience in geriatric patients because the disease/condition primarily occurs in pediatric 342 patients and/or younger adult patients (the disease/condition rarely occurs in geriatric patients) 343 38 21 CFR 201.57(c)(9)(v)(B)(1). 39 Ibid 40 21 CFR 201.57(c)(9)(v)(F).
Contains Nonbinding Recommendations Draft – Not for Implementation 11 (e.g., Duchenne muscular dystrophy), the Geriatric Use subsection may contain the following or 344 another appropriate and accurate alternative statement: 345 346 “Disease A is largely a disease of pediatric and young adult patients. Clinical studies of 347 DRUG X did not include patients 65 years of age and older.” 348 349 If clinical studies primarily included geriatric patients and did not include sufficient numbers of 350 younger adult patients to determine whether geriatric patients respond differently than younger 351 adult patients, and there has been no other reported clinical experience in geriatric patients, we 352 recommend that the Geriatric Use subsection contain a statement clarifying why there is 353 insufficient information to detect differences in safety or effectiveness between geriatric and 354 younger adult patients. The following is an example of such a statement in this situation: 355 356 “Clinical studies of DRUG X did not include sufficient numbers of younger adult patients to 357 determine if patients 65 years of age and older respond differently than younger adult 358 patients.” 359 360 3. Additional Required and Recommended Information in the Geriatric Use Subsection 361 (Scenarios 1.1, 1.2, and 1.3) 362 363 a. Specific risks or safety concerns in geriatric patients — Geriatric Use 364 subsection (scenarios 1.1, 1.2, and 1.3) 365 366 The Geriatric Use subsection must also include specific risks or safety concerns (hazards) 367 associated with the use of the drug in geriatric patients and any need for specific monitoring, as 368 well as other information related to the safe and effective use of the drug in the geriatric 369 population.41 If appropriate, the hazard must be summarized in the BOXED WARNING, 370 CONTRAINDICATIONS, and/or WARNINGS AND PRECAUTIONS sections.42 The 371 following is an example of how to include information in the Geriatric Use subsection and cross- 372 reference other relevant sections for a drug associated with greater sedation and delirium in 373 geriatric patients compared to younger adult patients: 374 375 “Because DRUG X-treated geriatric patients (patients 65 years of age and older) had a higher 376 rate of sedation and delirium than control-treated geriatric patients (the rates were similar 377 between DRUG X-treated and control-treated younger adult patients), initiate DRUG X at a 378 lower dosage in geriatric patients [see Dosage and Administration (2.x) and Warnings and 379 Precautions (5.x)].” 380 381 41 21 CFR 201.57(c)(9)(v)(A), (B)(3), and (D). 42 21 CFR 201.57(c)(9)(v)(D) and 21 CFR 201.57(c)(1), (5), and (6).

Summarizing specific pharmacokinetic or pharmacodynamic studies in 382 geriatric patients — Geriatric Use subsection (scenarios 1.1, 1.2, and 1.3) 383 384 If specific pharmacokinetic or pharmacodynamic studies have been carried out in geriatric 385 patients, they must be summarized in the Geriatric Use subsection and described in detail in the 386 CLINICAL PHARMACOLOGY section43 (the Geriatric Use subsection should include a cross- 387 reference to the CLINICAL PHARMACOLOGY section). For the fictitious drug DRUG X 388 (drugozide injection), examples of such statements in the Geriatric Use subsection include the 389 following: 390 391 • Example 1: 392 393 “Geriatric patients had higher plasma drugozide C max and AUC compared to younger 394 adult patients, and the plasma drugozide C max and AUC observed in geriatric patients 395 increases the risk of DRUG X-related adverse reactions [see Warnings and Precautions 396 (5.x) and Clinical Pharmacology (12.3)]. Therefore, the recommended dosage of DRUG 397 X in geriatric patients is lower than in younger adult patients [see Dosage and 398 Administration (2.x)].”44 399 400 • Example 2: 401 402 “No clinically meaningful differences in the pharmacokinetics of drugozide were 403 observed in geriatric patients compared to younger adult patients [see Clinical 404 Pharmacology (12.3)].” 405 406 c. When a drug is known to be substantially excreted by the kidney — 407 Geriatric Use subsection (scenarios 1.1, 1.2, and 1.3) 408 409 If the drug is known to be substantially excreted by the kidney, the Geriatric Use subsection 410 must include the following statement:45 411 412 “This drug is known to be substantially excreted by the kidney, and the risk of adverse 413 reactions to this drug may be greater in patients with impaired renal function. Because 414 elderly patients are more likely to have decreased renal function, care should be taken in dose 415 selection, and it may be useful to monitor renal function.” 416 417 An alternative statement may be permitted, if the FDA determines that such statement is accurate 418 and appropriate.46 Permissible changes may include, but are not limited to, the following: 419 420 43 21 CFR 201.57(c)(9)(v)(C)(1). 44 The term Cmax refers to maximum plasma concentration. The term AUC refers to area under the curve. 45 21 CFR 201.57(c)(9)(v)(C)(2). 46 21 CFR 201.57(c)(9)(v)(F).
Contains Nonbinding Recommendations Draft – Not for Implementation 13 • Removing the phrase “risk of adverse reactions to this drug may be greater in patients 421 with impaired renal function” if the risk of adverse reactions is the same in patients with 422 renal impairment and in patients with normal renal function (e.g., the drug has a high 423 therapeutic index). 424 425 • Using the term geriatric patients rather than elderly patients. 426 427 • Removing the following phrase if the drug has only one recommended dosage or if the 428 labeling contains specific dosage recommendations for patients with renal impairment: 429 430 “Because elderly patients are more likely to have decreased renal function, care should be 431 taken in dose selection, and it may be useful to monitor renal function.” 432 433 • Removing the following phrase if the labeling includes specific recommendations for 434 monitoring renal function or if for the specific drug or disease/condition it would not be 435 useful to monitor for renal function: 436 437 “It may be useful to monitor renal function.” 438 439 Such changes would result in an alternative statement such as the following: 440 441 “DRUG X is substantially excreted by the kidney, and the risk of adverse reactions to DRUG 442 X may be greater in patients with renal impairment than in patients with normal renal 443 function. Because geriatric patients are more likely to have renal impairment, monitor for 444 Adverse Reactions Y and Z [see Warnings and Precautions (5.x) and Use in Specific 445 Populations (8.6)].” 446 447 Alternatively, this statement can be omitted if it is clearly inapplicable or misleading47 in the 448 Geriatric Use subsection (e.g., the drug is contraindicated or not recommended for use in 449 patients with moderate or severe renal impairment).48 450 451 If the drug is known to be substantially excreted by the kidney, the Geriatric Use subsection 452 should, as appropriate, include a cross-reference to the Renal Impairment subsection (if any) in 453 the USE IN SPECIFIC POPULATIONS section,49 where clinically relevant details regarding use 454 in patients with renal impairment would be included. 455 456 47 See 21 CFR 201.56(a)(2) and 21 CFR 201.56(d)(4). 48 In this example, information about the risks of use of the drug in patients with renal impairment would be described elsewhere in labeling (e.g., CONTRAINDICATIONS section, WARNINGS AND PRECAUTIONS section, Renal Impairment subsection in the USE IN SPECIFIC POPULATIONS section). 49 See the draft guidance for industry Pharmacokinetics in Patients with Impaired Renal Function — Study Design, Data Analysis, and Impact on Dosing and Labeling (March 2010).

Contains Nonbinding Recommendations Draft – Not for Implementation 14 B. Including Geriatric Use Information in Other Sections of Labeling 457 (Scenarios 1.1, 1.2, and/or 1.3) 458 459 When the drug is approved for use generally in adult patients including geriatric patients (or a 460 subset of the geriatric population), information about geriatric use may be required in other 461 sections of the labeling. The following discusses both requirements and recommendations as to 462 placement of geriatric use information in the relevant sections of labeling. The required and 463 recommended information apply to scenarios 1.1, 1.2, and 1.3 unless otherwise noted. 464 465 • INDICATIONS AND USAGE: If a drug is indicated for use in the entire adult 466 population (including geriatric patients), then in general, the term adults should be 467 incorporated into the indication.50 For example: 468 469 “DRUG X is indicated for the treatment of Indication A in adults.” 470 471 • DOSAGE AND ADMINISTRATION: Typically, the recommended dosage in geriatric 472 patients is the same as the recommended dosage in younger adult patients. However, the 473 DOSAGE AND ADMINISTRATION section must include the recommended dosage in 474 geriatric patients if the recommended dosage in geriatric patients differs from the 475 recommended dosage in younger adult patients.51 476 477 • WARNINGS AND PRECAUTIONS: Clinically significant adverse reactions or risks 478 that are unique to geriatric patients must be included in the WARNINGS AND 479 PRECAUTIONS section,52 and clinically significant adverse reactions or risks that occur 480 at a greater severity or frequency than in younger adult patients should generally also be 481 included in this section (generally applies to scenario 1.2).53 482 483 • ADVERSE REACTIONS: If there are differences in the frequency, severity, or type of 484 adverse reactions in geriatric patients compared to younger adult patients or if there are 485 adverse reactions that are unique to geriatric patients, details of these adverse reaction 486 data should be included in the ADVERSE REACTIONS section (generally applies to 487 scenario 1.2).54 However, if there are no differences in frequency (e.g., no differences in 488 relative or absolute risk), severity, or type of adverse reactions in geriatric patients 489 50 See the draft guidance for industry Indications and Usage Section of Labeling for Human Prescription Drug and Biological Products — Content and Format (July 2018). When final, this guidance will represent the FDA’s current thinking on this topic. 51 See 21 CFR 201.57(c)(3)(C) and (H). 52 See 21 CFR 201.57(c)(9)(v)(D) and 21 CFR 201.57(c)(6). 53 See generally the guidance for industry Warnings and Precautions, Contraindications, and Boxed Warning Sections of Labeling for Human Prescription Drug and Biological Products — Content and Format (October 2011). 54 See the guidance for industry Adverse Reactions Section of Labeling for Human Prescription Drug and Biological Products — Content and Format (January 2006).
Contains Nonbinding Recommendations Draft – Not for Implementation 15 compared to younger adult patients, it is not necessary to separately present adverse 490 reactions from geriatric patients in this section (generally applies to scenarios 1.1 and 491 1.3). 492 493 • CLINICAL PHARMACOLOGY: The CLINICAL PHARMACOLOGY section must 494 include detailed descriptions of pharmacokinetic and/or pharmacodynamic study data if 495 such studies were carried out in geriatric patients55 and should include relevant 496 pharmacogenomic study data, data obtained from population analyses, and dose response 497 information.56 498 499 • CLINICAL STUDIES: Clinical studies that provide substantial evidence of 500 effectiveness for use of a drug in the geriatric population should be described in the 501 CLINICAL STUDIES section (e.g., study design(s), population(s), endpoint(s), results 502 and limitations of the study design or evidence).57 503 504 505 V. DRUG IS APPROVED FOR A GERIATRIC-SPECIFIC INDICATION 506 (SCENARIO 2) 507 508 When a drug is approved for use for a geriatric-specific indication, the labeling must provide a 509 summary of information essential for safe and effective use in geriatric patients.58 The following 510 describes both requirements and recommendations regarding placement of geriatric use 511 information in relevant sections of labeling when a drug is approved for a geriatric-specific 512 indication: 513 514 • INDICATIONS AND USAGE: All geriatric indications supported by adequate and 515 well-controlled studies in geriatric patients must be included in the INDICATIONS AND 516 USAGE section.59 If the drug is indicated for use only in geriatric patients, in general, 517 the FDA recommends using the phrases “patients XX years of age and older,” “adults 518 XX years of age and older,” or similar phrases in the indication. For example: 519 520 “DRUG X is indicated for the treatment of Indication A in patients 65 years of age 521 and older.” 522 523 55 21 CFR 201.57(c)(9)(v)(C)(1) and 21 CFR 201.57(c)(13). 56 See the guidance for industry Clinical Pharmacology Section of Labeling for Human Prescription Drug and Biological Products — Content and Format (December 2016). 57 See the guidance for industry Clinical Studies Section of Labeling for Human Prescription Drug and Biological Products — Content and Format (January 2006). 58 21 CFR 201.56(a)(1). 59 21 CFR 201.57(c)(9)(v)(A).
Contains Nonbinding Recommendations Draft – Not for Implementation 16 • DOSAGE AND ADMINISTRATION: This section must include the recommended 524 dosage in geriatric patients for all approved geriatric-specific indications.60 525 526 • ADVERSE REACTIONS: Geriatric adverse reaction data must be included in the 527 ADVERSE REACTIONS section.61 528 529 • USE IN SPECIFIC POPULATIONS, Geriatric Use subsection: Only a summary 530 statement of the approved geriatric indication(s) should be described in the Geriatric Use 531 subsection. For example: 532 533 “DRUG X is indicated in patients 65 years of age and older (for Indication A), and 534 the information on this use is discussed throughout the labeling.” 535 536 • CLINICAL PHARMACOLOGY: Data summarized in the Geriatric Use subsection 537 must be discussed in more detail, if appropriate, in the CLINICAL PHARMACOLOGY 538 section.62 Detailed descriptions of geriatric pharmacokinetic, pharmacodynamic, and/or 539 pharmacogenomic study data; relevant data obtained from population analyses; and dose 540 response information should be included in this section.63 541 542 • CLINICAL STUDIES: Data summarized in the Geriatric Use subsection must be 543 discussed in more detail, if appropriate, in the CLINICAL STUDIES section.64 Detailed 544 descriptions of studies that provide substantial evidence of effectiveness for use in 545 geriatric patients (e.g., study design(s), population(s), endpoint(s), results and limitations 546 of the study design or evidence) should be provided in this section.65 547 548 549 VI. DRUG IS NOT APPROVED IN THE GERIATRIC POPULATION 550 551 Drugs that are studied only in younger adult patients (not geriatric patients) are typically 552 approved for all adult patients (including geriatric patients) because of generalizability of the 553 evidence to geriatric patients, consistencies in the disease processes across geriatric and younger 554 adults, and the drug’s overall benefits and risks. However, there are uncommon situations when 555 the evidence does not support the use of a drug in a geriatric population because clinical studies 556 60 21 CFR 201.57(c)(3)(C) and 21 CFR 201.57(c)(9)(v)(A). 61 21 CFR 201.57(c)(7). 62 21 CFR 201.57(c)(9)(v)(A) and 21 CFR 201.57(c)(9)(v)(C)(1). 63 See the guidance for industry Clinical Pharmacology Section of Labeling for Human Prescription Drug and Biological Products — Content and Format. See also 21 CFR 201.57(c)(13). 64 21 CFR 201.57(c)(9)(v)(A). 65 See the guidance for industry Clinical Studies Section of Labeling for Human Prescription Drug and Biological Products — Content and Format. See also 21 CFR 201.57(c)(15).
Contains Nonbinding Recommendations Draft – Not for Implementation 17 did not include a sufficient number of geriatric patients to support geriatric use for an 557 indication.66 Additionally, there are uncommon situations when the evidence does not support 558 the use of a drug in a geriatric population because the results of studies conducted in a geriatric 559 population strongly suggest that the drug is ineffective or the benefit-risk profile is unfavorable 560 (but the evidence falls short of warranting a contraindication).67 561 562 We recommend applicants contact the Agency if they have questions about developing labeling 563 for these uncommon situations. 564 565 If the use of the drug in geriatric patients is associated with a risk or safety concern (hazard) in 566 geriatric patients, the risk or safety concern must be described in the Geriatric Use subsection or, 567 if appropriate, must be stated in the CONTRAINDICATIONS and/or WARNINGS AND 568 PRECAUTIONS section(s), and the Geriatric Use subsection must cross-reference the section or 569 sections, if appropriate.68 Any such hazard must be stated in other sections of labeling (e.g., 570 BOXED WARNING), as appropriate.69 571 572 573 VII. OMITTING OR REVISING INFORMATION AND UPDATING LABELING 574 575 If an applicant believes that none of the requirements described in 21 CFR 201.57(c)(9)(v)(A) to 576 (E) is appropriate or relevant to its drug’s labeling, the applicant must provide a rationale for 577 omission of the statement(s) and may propose an alternative statement.70 The FDA may permit 578 omission of such statement(s) or alternative appropriate and accurate statement(s) if the FDA 579 determines that no statement(s) described in 21 CFR 201.57(c)(9)(v)(A) to (E) are appropriate or 580 relevant to the drug’s labeling.71 In some circumstances, applicants should omit specific 581 information otherwise required in the Geriatric Use subsection or omit the entire subsection 582 because the information is clearly inapplicable; applicants must omit such specific information or 583 66 These situations are different from situations when the entire Geriatric Use subsection is omitted because the information is clearly inapplicable or misleading (see section VII., Omitting or Revising Information and Updating Labeling). 67 Ibid. 68 21 CFR 201.57(c)(9)(v)(D). 69 The BOXED WARNING section requires that certain contraindications or serious warnings may be required by the FDA to be presented in a box (21 CFR 201.57(c)(1)). The WARNINGS AND PRECAUTIONS “section must describe clinically significant adverse reactions (including any that are potentially fatal, are serious even if infrequent, or can be prevented or mitigated through appropriate use of the drug), other potential safety hazards” (21 CFR 201.57(c)(6)(i)). The CONTRAINDICATIONS “section must describe any situations in which the drug should not be used because the risk of use (e.g., certain potentially fatal adverse reactions) clearly outweighs any possible therapeutic benefit … Known hazards and not theoretical possibilities must be listed” (21 CFR 201.57(c)(5)). 70 21 CFR 201.57(c)(9)(v)(F). 71 Ibid.
Contains Nonbinding Recommendations Draft – Not for Implementation 18 the entire subsection if it is misleading.72 For example, if a drug is indicated for use only in 584 neonates, the applicant should omit the Geriatric Use subsection because this subsection is 585 clearly inapplicable. We recommend applicants contact the Agency if they have questions about 586 omitting certain regulatory statements in the Geriatric Use subsection. 587 588 Labeling must be updated when new information becomes available that causes the labeling to 589 become inaccurate, false, or misleading.73 Consistent with this requirement, when revising 590 existing information in the labeling, applicants should evaluate labeling content to ensure that it 591 accurately reflects current knowledge about the use of the drug in geriatric patients for all 592 approved indications. Applicants should evaluate available results from postmarketing 593 controlled clinical studies, well-documented studies obtained from a literature search that are 594 available to the applicant and reasonably relevant to the use of the drug in geriatric patients, 595 pharmacokinetic and pharmacodynamic studies conducted in geriatric patients, and adverse 596 event reports.74 Applicants should review and update sections of labeling pertinent to the 597 geriatric use information as necessary when updating the labeling. 598 72 Under 21 CFR 201.56(a)(2), “labeling must be informative and accurate and neither promotional in tone nor false or misleading.” Under 21 CFR 201.56(d)(4), “[o]mit clearly inapplicable sections, subsections, or specific information.” For additional information on omitting information in labeling, see the guidance for industry Labeling for Human Prescription Drug and Biological Products — Implementing the PLR Content and Format Requirements (February 2013). 73 21 CFR 201.56(a)(2). 74 See 21 CFR 201.57(c)(9)(v)(B), which requires that such information be reflected in the Geriatric Use subsection.
