Indication

Breast Adjuvant indications Herceptin is indicated for adjuvant treatment of HER2-overexpressing node-positive or node-negative (ER/PR-negative or with one high-risk feature*) breast cancer:

  • As part of a treatment regimen containing doxorubicin, cyclophosphamide, and either paclitaxel or docetaxel
  • With docetaxel and carboplatin
  • As a single agent following multi-modality anthracycline-based therapy

* High-risk is defined as ER/PR positive with one of the following features: tumor size >2 cm, age

Breast Metastatic indications

Herceptin is indicated:

  • In combination with paclitaxel for the first line treatment of HER2-overexpressing metastatic breast cancer
  • As a single agent for treatment of HER2-overexpressing breast cancer in patients who have received one or more chemotherapy regimens for metastatic disease

Gastric

Herceptin is indicated in combination with cisplatin and capecitabine or 5-fluorouracil, for the treatment of patients with HER2 overexpressing metastatic gastric or gastroesophageal junction adenocarcinoma, who have not received prior treatment for metastatic disease.

Important Safety Information and BOXED WARNINGS

Boxed WARNINGS and Additional Important Safety Information

  • Herceptin administration can result in sub-clinical and clinical cardiac failure. The incidence and severity was highest in patients receiving Herceptin with anthracycline-containing chemotherapy regimens. In a pivotal adjuvant trial, one patient who developed CHF died of cardiomyopathy
  • Evaluate left ventricular function in all patients prior to and during treatment with Herceptin. Discontinue Herceptin treatment in patients receiving adjuvant therapy and withhold Herceptin in patients with metastatic disease for clinically significant decrease in left ventricular function
  • Herceptin administration can result in serious and fatal infusion reactions and pulmonary toxicity. Symptoms usually occur during or within 24 hours of Herceptin administration. Interrupt Herceptin infusion for dyspnea or clinically significant hypotension. Monitor patients until symptoms completely resolve. Discontinue Herceptin for anaphylaxis, angioedema, interstitial pneumonitis, or acute respiratory distress syndrome
  • Exposure to Herceptin 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
  • Exacerbation of chemotherapy-induced neutropenia has also occurred
  • Detection of HER2 protein overexpression is necessary for selection of patients appropriate for Herceptin therapy
  • The most common adverse reactions associated with Herceptin in breast cancer were fever, nausea, vomiting, infusion reactions, diarrhea, infections, increased cough, headache, fatigue, dyspnea, rash, neutropenia, anemia, and myalgia
  • The most common adverse reactions associated with Herceptin in metastatic gastric cancer were neutropenia, diarrhea, fatigue, anemia, stomatitis, weight loss, upper respiratory tract infections, fever, thrombocytopenia, mucosal inflammation, nasopharyngitis, and dysgeusia
