Drug Safety-related Labeling Changes (SrLC) Database

ANDA	Abbreviated New Drug Application
BLA	Biologics License Application
CDER	Center for Drug Evaluation and Research
MG	Medication Guide
NDA	New Drug Application
PCI	Patient Counseling Information
PI	Patient Information
PLR	Physician Labeling Rule
PLLR	Pregnancy and Lactation Labeling Rule
Italics	For the most part, italics indicate an FDA comment such as: Additions and/or revisions underlined These italics usually appear at the beginning of the section. In some cases, italics may be an inherent part of the label, and will most often appear in the body of the section.
Underlines	Any text that is underlined indicates text that has been added or revised. There are exceptions where underlining occurs in a section subtitle or heading. This is the case when there is just one word underlined in the body of the text.

Sections

BW	Box Warning
WP	Warnings and Precautions all in one section (PLR-format) Warnings as one section (pre-PLR format) Precautions as one section (pre-PLR format)
AR	Adverse Reactions (in pre-PLR format, this may be a subheading under precautions).
DI	Drug Interactions (in pre-PLR format, this may be a subheading under precautions).
USP	Use in Specific Populations (Inclusive on one or more of the following: Pregnancy; Lactation (PLLR- format); Nursing Mothers (pre-PLLR format); Females and Males of Reproductive Potential (PLLR format only); Pediatric Use, Geriatric Use, Renal Impairment, Hepatic Impairment, Sex, Race (these last six may be a subheading of precautions if label in pre-PLLR format.
PCI/PI/MG	Patient Counseling Information (PLR format only) - summarizes the information that a health care provider should convey to a patient (or caregiver when applicable) when a counseling discussion is taking place (e.g., a physician prescribing a drug during an office visit, a nurse providing discharge instructions at a hospital, or a pharmacist conveying information at a pharmacy). Patient Information - FDA approved patient labeling. Medication Guide - paper handouts that come with many prescription medicines. The guides address issues that are specific to particular drugs and drug classes, and they contain FDA-approved information that can help patients avoid serious adverse events.

Only NDAs and CDER regulated BLAs are included in this database. ANDAs are not included.

Applications that remain active, even if the product has been discontinued, undergo safety-related labeling changes.

6 Adverse Reactions

6.2 Postmarketing Experience

Newly created subsection:

The following adverse reactions have been identified during postmarketing use of KERYDIN. Because

these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug product exposure:

Hypersensitivity; contact allergy

8 Use in Specific Populations

8.1 Pregnancy

PLLR conversion, additions and/or revisions underlined:

Risk Summary

There are no available data on KERYDIN use in pregnant women to inform a drug associated risk for major birth defects, miscarriage or adverse maternal or fetal outcomes. In oral animal reproductive studies, administration of tavaborole during the period of organogenesis resulted in embryofetal toxicity and malformations at 570 times the Maximum Recommended Human Dose (MRHD) based on Area Under the Curve (AUC) comparisons in rats and embryofetal toxicity at 155 times the MRHD based on AUC comparisons in rabbits. Embryofetal toxicity was noted following dermal administration in rabbits up to 36 times the MRHD based on AUC comparisons.

The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies carry some risk of birth defect, loss, or other adverse outcomes. The background risk of major birth defects in the U.S. general population is 2% to 4% and of miscarriage is 15% to 20% of clinically recognized pregnancies.

8.2 Lactation

PLLR conversion; newly created subsection:

Risk Summary

There is no information available on the presence of KERYDIN in human milk, the effects of the drug on the breastfed infant or the effects of the drug on milk production after topical application of KERYDIN to women who are breastfeeding. KERYDIN is systemically absorbed. The lack of clinical data during lactation precludes a clear determination of the risk of KERYDIN to a breastfed infant. Therefore, the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for KERYDIN and any potential adverse effects on the breastfed child from KERYDIN or from the underlying maternal condition.

8.4 Pediatric Use

Additions and/or revisions underlined:

The safety and efficacy of KERYDIN were established in patients 6 years of age and older. Use of

KERYDIN in these age groups is supported by evidence from adequate and well-controlled studies of KERYDIN in adults with additional data from an open-label pharmacokinetics study of tavaborole in subjects 12 years to less than 17 years old.
