Description

11 DESCRIPTION Trastuzumab-qyyp is a humanized IgG1 kappa monoclonal antibody that selectively binds with high affinity to the extracellular domain of the human epidermal growth factor receptor 2 protein, HER2. Trastuzumab-qyyp is produced by recombinant DNA technology in a mammalian cell (Chinese Hamster Ovary) culture. TRAZIMERA (trastuzumab-qyyp) for injection is a sterile, white, preservative-free lyophilized powder with a cake-like appearance, for intravenous administration. Each multiple-dose vial of TRAZIMERA delivers 420 mg trastuzumab-qyyp, 7.9 mg L-histidine, 9.5 mg L-histidine HCl monohydrate, 1.7 mg polysorbate 20, and 386 mg sucrose. Reconstitution with 20 mL of the appropriate diluent (BWFI or SWFI) yields a solution containing 21 mg/mL trastuzumab-qyyp that delivers 20 mL (420 mg trastuzumab-qyyp), at a pH of approximately 6. If TRAZIMERA is reconstituted with SWFI without preservative, the reconstituted solution is considered single-dose. Each single-dose vial of TRAZIMERA delivers 150 mg trastuzumab-qyyp, 2.8 mg L-histidine, 3.4 mg L-histidine HCl monohydrate, 0.6 mg polysorbate 20, and 138 mg sucrose. Reconstitution with 7.4 mL of SWFI yields a solution containing 21 mg/mL trastuzumab-qyyp that delivers 7.15 mL (150 mg trastuzumab-qyyp), at a pH of approximately 6.

    • Dosage and Administration

    2 DOSAGE AND ADMINISTRATION For intravenous (IV) infusion only. Do not administer as an intravenous push or bolus. TRAZIMERA has different dosage and administration instructions than subcutaneous trastuzumab products. ( 2.3 ) Do not substitute TRAZIMERA (trastuzumab-qyyp) for or with ado-trastuzumab emtansine or fam-trastuzumab deruxtecan. ( 2.3 ) Perform HER2 testing using FDA-approved tests by laboratories with demonstrated proficiency. ( 1 , 2.2 ) Adjuvant Treatment of HER2-Overexpressing Breast Cancer ( 2.2 ) Administer at either:

  • Initial dose of 4 mg/kg over 90 minutes intravenous infusion, then 2 mg/kg over 30 minutes intravenous infusion weekly for 12 weeks (with paclitaxel or docetaxel) or 18 weeks (with docetaxel and carboplatin). One week after the last weekly dose of TRAZIMERA, administer 6 mg/kg as an intravenous infusion over 30 to 90 minutes every three weeks to complete a total of 52 weeks of therapy, or
  • Initial dose of 8 mg/kg over 90 minutes intravenous infusion, then 6 mg/kg over 30 to 90 minutes intravenous infusion every three weeks for 52 weeks. Metastatic HER2-Overexpressing Breast Cancer ( 2.3 )
  • Initial dose of 4 mg/kg as a 90 minutes intravenous infusion followed by subsequent weekly doses of 2 mg/kg as 30 minutes intravenous infusions. Metastatic HER2-Overexpressing Gastric Cancer ( 2.3 )
  • Initial dose of 8 mg/kg over 90 minutes intravenous infusion, followed by 6 mg/kg over 30 to 90 minutes intravenous infusion every 3 weeks. 2.1 Evaluation and Testing Before Initiating TRAZIMERA Assess left ventricular ejection fraction (LVEF) prior to initiation of TRAZIMERA and at regular intervals during treatment [see Boxed Warning , Dosage and Administration (2.5) and Warnings and Precautions (5.1) ] . Verify the pregnancy status of females of reproductive potential prior to the initiation of TRAZIMERA [see Warnings and Precautions (5.3) and Use in Specific Populations (8.1 , 8.3) ]. 2.2 Patient Selection Select patients based on HER2 protein overexpression or HER2 gene amplification in tumor specimens [see Indications and Usage (1) and Clinical Studies (14) ] . Assessment of HER2 protein overexpression and HER2 gene amplification should be performed using FDA-approved tests specific for breast or gastric cancers by laboratories with demonstrated proficiency. Information on the FDA-approved tests for the detection of HER2 protein overexpression and HER2 gene amplification is available at: http://www.fda.gov/CompanionDiagnostics . Assessment of HER2 protein overexpression and HER2 gene amplification in metastatic gastric cancer should be performed using FDA-approved tests specifically for gastric cancers due to differences in gastric vs. breast histopathology, including incomplete membrane staining and more frequent heterogeneous expression of HER2 seen in gastric cancers. Improper assay performance, including use of suboptimally fixed tissue, failure to utilize specified reagents, deviation from specific assay instructions,...

The most common adverse reactions in patients receiving trastuzumab products in the adjuvant and metastatic breast cancer setting are fever, nausea, vomiting, infusion reactions, diarrhea, infections, increased cough, headache, fatigue, dyspnea, rash, neutropenia, anemia, and myalgia. Adverse reactions requiring interruption or discontinuation of trastuzumab product treatment include CHF, significant decline in left ventricular cardiac function, severe infusion reactions, and pulmonary toxicity [see Dosage and Administration (2.5) ] . In the metastatic gastric cancer setting, the most common adverse reactions (≥ 10%) that were increased (≥ 5% difference) in the trastuzumab arm as compared to the chemotherapy alone arm were neutropenia, diarrhea, fatigue, anemia, stomatitis, weight loss, upper respiratory tract infections, fever, thrombocytopenia, mucosal inflammation, nasopharyngitis, and dysgeusia. The most common adverse reactions which resulted in discontinuation of treatment on the trastuzumab-containing arm in the absence of disease progression were infection, diarrhea, and febrile neutropenia. Adjuvant Breast Cancer The information below reflects exposure to one-year trastuzumab therapy across three randomized, open-label studies, NSABP B31, NCCTG N9831, and HERA, with (n = 3678) or without (n = 3363) trastuzumab in the adjuvant treatment of breast cancer. HERA Table 3 reflects exposure to trastuzumab in 1678 patients in HERA; the median treatment duration was 51 weeks and median number of infusions was 18 [see Clinical Studies (14.1) ].

    • Drug Interactions

    7 DRUG INTERACTIONS Anthracyclines Patients who receive anthracycline after stopping trastuzumab products may be at increased risk of cardiac dysfunction because of trastuzumab products estimated long washout period [see Clinical Pharmacology (12.3) ] . If possible, avoid anthracycline-based therapy for up to 7 months after stopping trastuzumab products. If anthracyclines are used, closely monitor the patient's cardiac function.

    Contraindications

    4 CONTRAINDICATIONS None.

  • None. ( 4 )

    • Pregnancy and Breastfeeding

    8.1 Pregnancy Risk Summary Trastuzumab products can cause fetal harm when administered to a pregnant woman. In post-marketing reports and published literature, use of trastuzumab products 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 a trastuzumab product is used in a pregnant woman or if a patient becomes pregnant within 7 months following the last dose of a trastuzumab product (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 TRAZIMERA 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 products 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 trastuzumab was stopped. In reported cases where trastuzumab therapy was resumed after amniotic index improved, oligohydramnios recurred. Animal Data In studies where trastuzumab was administered to pregnant cynomolgus monkeys during the period of organogenesis at doses up to 25...
