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.

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.

5 Warnings and Precautions

5.4 Patients with Compromised Respiratory Function

Additions and/or revisions underlined:

DAYVIGO has been studied in mild to severe Obstructive Sleep Apnea (OSA) and moderate to severe Chronic Obstructive Pulmonary Disease (COPD) in short-term clinical trials. The effect of DAYVIGO on respiratory function should be considered if prescribed to patients with compromised respiratory function [see Use in Specific Populations (8.8)].

8 Use in Specific Populations

8.8 Patients with Compromised Respiratory Function

Additions and/or revisions underlined:

Obstructive Sleep Apnea (OSA)

The respiratory depressant effect of DAYVIGO was evaluated after 8 consecutive nights of treatment with DAYVIGO 10 mg in a randomized, placebo-controlled, two-period crossover study in 37 patients with mild OSA (apnea-hypopnea index < 15 events per hour of sleep). Following once daily dosing of 10 mg, the mean treatment difference (DAYVIGO – placebo) on Day 8 for the apnea-hypopnea index was -0.06 (95% CI -19.5 to 1.83).

DAYVIGO was also evaluated after 8 consecutive nights of treatment with DAYVIGO 10 mg in a randomized, placebo-controlled, two-period crossover study in 33 patients with moderate to severe OSA (apnea-hypopnea index greater than or equal to 15 events per hour of sleep). Following once daily dosing of 10 mg, the mean treatment difference (DAYVIGO – placebo) on Day 8 for the apnea-hypopnea index was 0.80 (95% CI, -4.88 to 3.29).

Due to study limitations, including the short duration of the study, clinically meaningful respiratory effects of DAYVIGO in OSA cannot be excluded, including for long-term treatment [see Warnings and Precautions (5.4)].

Chronic Obstructive Pulmonary Disease (COPD)

The respiratory depressant effect of DAYVIGO was evaluated after 8 consecutive nights of treatment with DAYVIGO 10 mg in a randomized, placebo-controlled, two-period crossover study in 30 patients with moderate to severe COPD (Forced expiratory volume in the first second (FEV1)/Forced vital capacity (FVC) ratio less than or equal to 70% and 30% less than or equal to FEV1 < 80% of predicted). Following once-daily dosing of 10 mg, the mean treatment difference (DAYVIGO – placebo) on Day 8 for the mean peripheral capillary oxygen saturation during sleep was 0.47 (95% CI: 0.07 to 0.87).

DAYVIGO has not been studied in COPD patients with a FEV1 < 30% of predicted.

Clinically meaningful respiratory effects of DAYVIGO in patients with compromised respiratory function cannot be excluded [see Warnings and Precautions (5.4)].

8 Use in Specific Populations

8.1 Pregnancy

Additions and/or revisions underlined:

Risk Summary

Available data from a lactation study in 8 women indicates that lemborexant is transferred into the breastmilk of nursing mothers, and the results have established a mean daily infant dose of 0.0029 mg/kg/day and a relative infant dose of less than 2% of the maternal dose. These data support that transfer of lemborexant into breastmilk is low (see Data). There are no data on the effects of lemborexant on the breastfed infant, or the effects on milk production. Infants exposed to DAYVIGO through breastmilk should be monitored for excessive sedation. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for DAYVIGO and any potential adverse effects on the breastfed infant from DAYVIGO or from the underlying maternal condition.

Data

A single dose milk-only lactation study was conducted in 8 healthy adult lactating women. The mean amount of lemborexant recovered in human milk was 0.0174 mg following a 10 mg maternal dose.

The mean calculated daily infant oral dosage was 0.0029 mg/kg/day based on nominal infant body weight of 6 kg. Approximately 70% of the total amount of lemborexant excreted in milk was excreted by 24 hours after a single maternal dose administration. There are no data on the effects of lemborexant on the breastfed infant, the effects on milk production, or infant exposure after repeated maternal dosing of lemborexant.
