Terms & Conditions of Program
A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
Enhertu (trastuzumab deruxtecan) is an antibody-drug conjugate (ADC) composed of a humanized anti-HER2 monoclonal antibody linked to a topoisomerase I inhibitor. It is indicated for the treatment of adult patients with HER2-positive or HER2-low breast cancer, HER2-positive gastric or gastroesophageal junction adenocarcinoma, and other HER2-expressing solid tumors as approved indications evolve. Enhertu delivers cytotoxic chemotherapy directly to HER2-expressing cancer cells, leveraging targeted delivery to maximize efficacy and minimize off-target toxicity. It has demonstrated significant clinical benefit in patients with heavily pretreated or refractory cancers.

Enhertu is administered via intravenous infusion once every three weeks (21-day cycle). The recommended dose is 5.4 mg/kg for breast cancer and 6.4 mg/kg for gastric cancer, adjusted as needed based on tolerability and clinical response. The first infusion should be given over 90 minutes; if well tolerated, subsequent doses may be infused over 30 minutes. Premedication may be used to prevent infusion reactions. Dose reductions, delays, or discontinuation may be required for adverse events, particularly hematologic toxicity or interstitial lung disease (ILD).
Each Enhertu vial contains:
Enhertu is contraindicated in patients with:
Enhertu carries a boxed warning for interstitial lung disease (ILD) and pneumonitis, which may be fatal. All patients should be monitored for signs of pulmonary toxicity, including cough, dyspnea, and new radiographic findings. Prompt dose interruption and corticosteroid treatment are warranted for suspected ILD. Neutropenia, anemia, and left ventricular dysfunction have been reported and require regular monitoring. Effective contraception is required during treatment and for at least 7 months after the last dose in women of childbearing potential, and for 4 months in male partners. Enhertu is not recommended during pregnancy or breastfeeding.
