8 Use in Specific Populations

8.1  Pregnancy

(Pregnancy and Lactation Labeling Rule (PLLR) conversion; please refer to label)

8.2  Lactation

(Pregnancy and Lactation Labeling Rule (PLLR) conversion; additions and/or revisions underlined)

The Centers for Disease Control and Prevention recommends that HIV-infected mothers in the United States not breastfeed their infants to avoid risking postnatal transmission of HIV-1.

There are no data available regarding the presence of saquinavir in human milk, the effects on the breastfed infant, or the effects on milk production.

Because of the potential for (1) HIV-1 transmission (in HIV-negative infants), (2) developing viral resistance (in HIV-positive infants) and (3) adverse reactions in breastfed infants similar to those seen in adults, instruct mothers not to breastfeed if they are receiving INVIRASE.

17 Patient Counseling Information

(Additions and/or revisions underlined)

Pregnancy Exposure Registry

Advise patients that there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antiretrovirals during pregnancy.

Lactation

Instruct mothers with HIV-1 infection not to breastfeed because HIV-1 can be passed to the baby in breast milk.

5 Warnings and Precautions

5.1 Importance of Co-administration with Ritonavir

(new subsection header added)

INVIRASE must be used in combination with ritonavir. Please refer to the ritonavir full prescribing information for additional precautionary measures.

INVIRASE is not recommended for use in combination with cobicistat. Dosing recommendations for this combination have not been established. Cobicistat is also not recommended in combination with regimens containing ritonavir due to similar effects of cobicistat and ritonavir on CYP3A. Please refer to the cobicistat full prescribing information for additional precautionary measures.

5.2 Risk of Serious Adverse Reactions Due to Drug Interactions

(additions underlined)

…

If a serious or severe toxicity occurs during treatment with INVIRASE/ritonavir, discontinue INVIRASE/ritonavir. For concomitantly used drugs including antiretroviral agents used in combination with INVIRASE/ritonavir, physicians should refer to the complete product information for these drugs for dose adjustment recommendations and for information regarding drug-associated adverse reactions.

5.3 PR Interval Prolongation

(additions underlined)

INVIRASE/ritonavir prolongs the PR interval in a dose-dependent fashion. Cases of second or third degree atrioventricular block have been reported rarely. Patients with underlying structural heart disease, pre-existing conduction system abnormalities, cardiomyopathies and ischemic heart disease may be at increased risk for developing cardiac conduction abnormalities. ECG monitoring is recommended in these patients. Discontinue INVIRASE/ritonavir if significant arrhythmias, QT or PR prolongation occur.

The impact on the PR interval of coadministration of INVIRASE/ritonavir with other drugs that prolong the PR interval (including calcium channel blockers, beta-adrenergic blockers, digoxin and atazanavir) has not been evaluated. As a result, coadministration of INVIRASE/ritonavir with these drugs should be undertaken with caution, particularly with those drugs metabolized by CYP3A, and clinical monitoring is recommended.

For concomitantly used drugs, including antiretroviral agents used in combination with INVIRASE/ritonavir, physicians should refer to the complete product information for these drugs for dose adjustment recommendations and for information regarding drug- associated adverse reactions.

5.4 QT Interval Prolongation

(additions underline)

…

For concomitantly used drugs including antiretroviral agents used in combination with INVIRASE/ritonavir, refer to the complete product information for these drugs for dose adjustment recommendations and for information regarding drug- associated adverse reactions.Discontinue INVIRASE/ritonavir if significant arrhythmias, QT or PR prolongation occurs.

Patients initiating therapy with INVIRASE/ritonavir:

An ECG should be performed prior to initiation of treatment. Patients with a QT interval ? 450 msec should not initiate treatment with INVIRASE/ritonavir.

Treatment-naïve patients initiating treatment with INVIRASE/ritonavir should receive a reduced starting dose of INVIRASE 500 mg twice daily with ritonavir 100 mg twice daily for the first 7 days of treatment followed by INVIRASE/ritonavir 1000/100 mg twice daily due to potential for an increased risk of PR and QT interval prolongation with the standard 1000/100 mg twice daily dose.

For patients with a baseline QT interval < 450 msec, an on-treatment ECG is recommended after approximately 10 days of therapy. Discontinue INVIRASE/ritonavir in patients with a QT interval prolongation > 20 msec over pre-treatment.

…

5.6 Hepatotoxicity

(additions underlined)

In patients with underlying hepatitis B or C, cirrhosis, chronic alcoholism or other underlying liver abnormalities, there have been reports of worsening of the underlying liver disease and development of portal hypertension after starting INVIRASE/ritonavir. Jaundice and exacerbation of chronic liver disease with grade 4 elevated liver function tests were also observed. No dosage adjustment is necessary for patients with mild or moderate hepatic impairment based on limited data. INVIRASE/ritonavir is contraindicated in patients with severe hepatic impairment. If a serious or severe toxicity occurs during treatment with INVIRASE/ritonavir, discontinue INVIRASE/ritonavir.
