HERCEPTIN HYLECTA (trastuzumab and hyaluronidase-oysk)
HERCEPTIN HYLECTA is indicated for the treatment of Breast Cancer.
How HERCEPTIN HYLECTA Works
Trastuzumab is a HER2/neu receptor antagonist that binds to the HER2 protein to inhibit the proliferation of human tumor cells. It also functions as a mediator of antibody-dependent cellular cytotoxicity, which preferentially targets cancer cells that overexpress HER2. The hyaluronidase component acts as an endoglycosidase that temporarily depolymerizes hyaluronan in the subcutaneous tissue. This increases the permeability of the tissue, which enhances the absorption rate of trastuzumab into the systemic circulation.

HERCEPTIN HYLECTA Boxed 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.

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 Tox
HERCEPTIN HYLECTA Target & Pathway
ProTarget
A receptor tyrosine kinase that promotes cell growth and division. Approximately 20% of breast cancers overexpress HER2, leading to aggressive tumor growth. Targeting HER2 blocks these growth signals and can trigger immune-mediated destruction of cancer cells.
Pathway Context
HER2 forms dimers with other HER family members to activate growth signaling
A receptor that triggers cell growth, proliferation, and survival when activated. Mutations or overexpression of EGFR drive many cancers, particularly lung cancer. Blocking EGFR stops the growth signals that fuel tumor progression.
