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

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.

8 Use in Specific Populations

8.4 Pediatric Use

Additions and/or revisions underlined:

The safety and effectiveness of LAMPIT have been established for the treatment of Chagas disease (American Trypanosomiasis) caused by Trypanosoma cruzi in pediatric patients from birth to less than 18 years of age weighing at least 2.5 kg. The efficacy of LAMPIT was demonstrated in pediatric patients 0 to 4 years of age in Trial 1 based on seroconversion to negative on lysate ELISA, recombinant ELISA and IHA at 4 years post-treatment compared to untreated patients. The efficacy of LAMPIT in pediatric patients 5 to <18 years of age was extrapolated from efficacy established in the younger pediatric population. Supportive evidence of efficacy was provided by seroconversion to negative on the F29 ELISA [see Clinical Studies (14)].

The safety and effectiveness of LAMPIT has not been established in pediatric patients weighing less than 2.5 kg.

5 Warnings and Precautions

5.2 Embryo-Fetal Toxicity

Additions and/or revisions underlined:

Based on findings from animal studies, LAMPIT can cause fetal harm when administered to a pregnant woman. In animal reproduction studies, nifurtimox administered orally to pregnant rats, and rabbits during organogenesis was associated with reduced maternal body weights in rats, and abortions, fetal death, and smaller litter sizes in rabbits at doses approximately equivalent to and 2-times, respectively, the maximum recommended human dose (MRHD) of 10 mg/kg/day. Fetal malformations were observed in pregnant rabbits administered nifurtimox doses less than the MRHD [see Use in Specific Populations (8.1)].

Data

Animal Data

In an embryo-fetal toxicity study in pregnant rats, 15, 30, and 60 mg/kg/day nifurtimox was administered orally during the period of organogenesis (GD 6 to GD 17). Maternal body weights, body weight gain, and food consumption were reduced in the 60 mg/kg/day dose group. Treatment with nifurtimox did not produce fetal toxicity and no nifurtimox-related fetal malformations were observed. No maternal toxicity was observed at 30 mg/kg/day nifurtimox (approximately 0.5 times the MRHD based on body surface area comparison) and no adverse fetal effects were observed at 60 mg/kg/day nifurtimox (approximately equivalent to the MRHD based on body surface area comparison).
