Boxed warning
WARNING: CARDIOMYOPATHY, EMBRYO-FETAL TOXICITY, and PULMONARY TOXICITY WARNING: CARDIOMYOPATHY, EMBRYO-FETAL TOXICITY, and PULMONARY TOXICITY See full prescribing information for complete boxed warning. Cardiomyopathy: HERCEPTIN HYLECTA can result in subclinical and clinical cardiac failure manifesting as CHF, and decreased LVEF, with greatest risk when administered concurrently with anthracyclines. Evaluate cardiac function prior to and during treatment. Discontinue HERCEPTIN HYLECTA for cardiomyopathy. ( 2.4 , 5.1 ) Pulmonary Toxicity: Discontinue HERCEPTIN HYLECTA for anaphylaxis, angioedema, interstitial pneumonitis or acute respiratory distress syndrome.
( 5.3 ) Embryo-Fetal Toxicity: Exposure to HERCEPTIN HYLECTA during pregnancy can result in oligohydramnios, in some cases complicated by pulmonary hypoplasia and neonatal death. Advise patients of these risks and the need for effective contraception. ( 5.2 , 8.1 , 8.3 ) Cardiomyopathy HERCEPTIN HYLECTA administration can result in sub - clinical and clinical cardiac failure. The incidence and severity was highest in patients receiving HERCEPTIN HYLECTA with anthracycline - containing chemotherapy regimens. Evaluate left ventricular function in all patients prior to and during treatment with HERCEPTIN HYLECTA.
Discontinue HERCEPTIN HYLECTA treatment in patients receiving adjuvant therapy and withhold HERCEPTIN HYLECTA in patients with metastatic disease for clinically significant decrease in left ventricular function [see Dosage and Administration (2.4) and Warnings and Precautions (5.1) ]. Pulmonary Toxicity HERCEPTIN HYLECTA administration can result in serious and fatal pulmonary toxicity. Symptoms usually occur during or within 24 hours of HERCEPTIN HYLECTA administration. Discontinue HERCEPTIN HYLECTA for anaphylaxis, angioedema, interstitial pneumonitis, or acute respiratory distress syndrome [see Warnings and Precautions (5.3 , 5.5) ] . Monitor patients until symptoms completely resolve.
Embryo-Fetal Toxicity Exposure to HERCEPTIN HYLECTA during pregnancy can result in oligohydramnios and oligohydramnios sequence manifesting as pulmonary hypoplasia, skeletal abnormalities, and neonatal death. Advise patients of these risks and the need for effective contraception [see Warnings and Precautions (5.2) and Use in Specific Populations (8.1 , 8.3) ].

Administration and Storage To prevent medication errors, it is important to check the vial labels to ensure that the drug being prepared and administered is HERCEPTIN HYLECTA and not ado-trastuzumab emtansine or intravenous trastuzumab. HERCEPTIN HYLECTA should be administered by a healthcare professional. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.
Do not use vial if particulates or discoloration is present. Discard any unused portion remaining in the vial. HERCEPTIN HYLECTA is for single use only. The 600 mg/10,000 units (600 mg trastuzumab and 10,000 units hyaluronidase) solution is a ready to use solution for injection which does not need to be diluted. To avoid needle clogging, attach the hypodermic injection needle to the syringe immediately prior to administration followed by volume adjustment to 5 mL.
HERCEPTIN HYLECTA is compatible with polypropylene and polycarbonate syringe material and stainless steel transfer and injection needles. Prepare the dosing syringe in controlled and validated aseptic conditions. After the solution of HERCEPTIN HYLECTA is withdrawn from the vial and into the syringe, replace the transfer needle with a syringe closing cap.
Label the syringe with the peel-off sticker. Administration The injection site should be alternated between the left and right thigh. New injections should be given at least 2.5 cm from the old previous site on healthy skin and never into areas where the skin is red, bruised, tender, or hard, or areas where there are moles or scars.
During the treatment course with HERCEPTIN HYLECTA other medicinal products for subcutaneous administration should preferably be injected at different sites. The dose should be administered subcutaneously over approximately 2 to 5 minutes. Storage If the syringe containing HERCEPTIN HYLECTA is not used immediately, then the syringe can be stored in the refrigerator (2°C to 8°C) for up to 24 hours and subsequently at room temperature (20°C to 25°C) for up to 4 hours.
Protect from light. Do not shake or freeze.

- Trastuzumab and hyaluronidase (human recombinant)
Label text (1 paragraph)
Anthracyclines Patients who receive anthracycline after stopping HERCEPTIN HYLECTA may be at increased risk of cardiac dysfunction because of HERCEPTIN HYLECTA's estimated long washout period [see Clinical Pharmacology (12.3) ] . If possible, avoid anthracycline-based therapy for up to 7 months after stopping HERCEPTIN HYLECTA. If anthracyclines are used, closely monitor the patient's cardiac function.

Pregnancy and lactation
Pregnancy
8.1 Pregnancy If HERCEPTIN HYLECTA is administered during pregnancy, or if a patient becomes pregnant while receiving HERCEPTIN HYLECTA or within 7 months following the last dose of HERCEPTIN HYLECTA, health care providers and patients should immediately report HERCEPTIN HYLECTA exposure to Genentech at 1-888-835-2555. Risk Summary HERCEPTIN HYLECTA can cause fetal harm when administered to a pregnant woman. In post-marketing reports and published literature, use of trastuzumab during pregnancy resulted in cases of oligohydramnios and of oligohydramnios sequence, manifesting as pulmonary hypoplasia, skeletal abnormalities, and neonatal death [see Data ].
Apprise the patient of the potential risks to a fetus. There are clinical considerations if HERCEPTIN HYLECTA is used in a pregnant woman or if a patient becomes pregnant within 7 months following the last dose of HERCEPTIN HYLECTA [see Clinical Considerations ]. The background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Clinical Considerations Fetal/Neonatal Adverse Reactions Monitor women who received HERCEPTIN HYLECTA during pregnancy or within 7 months prior to conception for oligohydramnios. If oligohydramnios occurs, perform fetal/neonatal testing that is appropriate for gestational age and consistent with community standards of care. Data Human Data In post-marketing reports and published literature, use of trastuzumab during pregnancy resulted in cases of oligohydramnios and of oligohydramnios sequence. Fetal manifestations included pulmonary hypoplasia, skeletal abnormalities, and neonatal death.
These case reports described oligohydramnios in pregnant women who received trastuzumab either alone or in combination with chemotherapy. In most reported cases, amniotic fluid index increased after use of trastuzumab was stopped. In reported cases where Herceptin therapy was resumed after amniotic index improved, oligohydramnios recurred. Animal Data HERCEPTIN HYLECTA for subcutaneous injection contains trastuzumab and hyaluronidase [see Description (11) ] .
Trastuzumab : In studies where intravenous trastuzumab was administered to pregnant cynomolgus monkeys during the period of organogenesis at doses up to 25 mg/kg given twice weekly (up to 25 times the recommended weekly human dose of 2 mg/kg), trastuzumab crossed the placental barrier during the early (Gestation Days 20 to 50) and…
