HERCEPTIN (trastuzumab)
HERCEPTIN is indicated for the treatment of HER2-overexpressing adjuvant breast cancer; HER2-overexpressing metastatic breast cancer; HER2-overexpressing metastatic gastric or gastroesophageal junction adenocarcinoma.
How HERCEPTIN Works
Herceptin targets the HER2 proto-oncogene, which encodes a 185 kDa transmembrane receptor protein related to the epidermal growth factor receptor. By binding to this receptor, the drug inhibits the proliferation of human tumor cells that overexpress HER2. Additionally, Herceptin functions as a mediator of antibody-dependent cellular cytotoxicity (ADCC), a process that preferentially exerts its effects on cancer cells that overexpress HER2 compared to those that do not.

WARNING: CARDIOMYOPATHY, INFUSION REACTIONS, EMBRYO-FETAL TOXICITY, and PULMONARY TOXICITY WARNING: CARDIOMYOPATHY, INFUSION REACTIONS, EMBRYO-FETAL TOXICITY, and PULMONARY TOXICITY See full prescribing information for complete boxed warning Cardiomyopathy: Herceptin 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 for cardiomyopathy. ( 2.5 , 5.1 ) Infusion Reactions, Pulmonary Toxicity: Discontinue Herceptin for anaphylaxis, angioedema, interstitial pneumonitis, or acute respiratory distress syndrome. ( 5.2 , 5.4 ) Embryo-Fetal Toxicity: Exposure to Herceptin 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. ( 5.3 , 8.1 , 8.3 ) Cardiomyopathy 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. 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 [see Dosage and Administration (2.5) and Warnings and Precautions (5.1)] . Infusion Reactions; Pulmonary Toxicity 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
HERCEPTIN 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.

How We Calculate These Metrics
Trial Activity Stage
Measures the current development activity pattern based on trial phases, status, and trends. Important: This measures R&D activity, not commercial lifecycle.
Trial statuses: "Active" means recruiting or ongoing. "Completed" means reached planned endpoint. "Terminated" means stopped early—often due to safety, efficacy, or business reasons.
- Growth: High proportion of early-phase trials (Phase 1/2), active development
- Expansion: Significant Phase 3 activity, approaching or pursuing approvals
- Mature: Substantial Phase 4 post-marketing studies
- Stable: Mixed phase distribution, steady development
- Declining: Low active trial ratio, reduced R&D investment
