Cost and Insurance
Cost and insurance can be a major concern when it comes to Enhertu treatment. The price of Enhertu varies depending on factors such as the form of the drug, the length of treatment, and whether there are payment assistance programs available.
Typically, IV infusions or subcutaneous injections cost more than oral tablets. For example, Enhertu and Herceptin are both available as IV infusions, while Tykerb comes as an oral tablet.
Insurance can help cover some of the costs, but prior authorization may be required. This means the insurance company and your doctor will discuss Enhertu as part of your treatment, and the company will determine whether the medication is covered.
Cancer treatments can be extremely costly, with Americans paying around $5.6 billion per year in out-of-pocket costs. Many people with cancer pay over $100,000 out-of-pocket costs within the first year of diagnosis.
There are options available to help with the cost of Enhertu, including the Enhertu patient savings program, patient-assistance programs, and independent foundations. These options can help with drug cost and other expenses related to treatment, including drug administration and transportation expenses.
Here are some factors to consider when it comes to insurance and Enhertu:
- Whether there are payment assistance programs for your prescribed treatment
- Whether you’re paying out of pocket or have insurance
- The type of insurance coverage you have and where you receive your Enhertu doses
Enhertu Treatment
Enhertu targets a protein called Human Epidermal growth factor Receptor 2 (HER-2) on the surface of breast cancer cells.
It works by binding to the breast cancer cell and releasing a molecule called deruxtecan (DXd), which stops breast cancer cells from growing and dividing.
Enhertu is indicated for adults with HER2-positive breast cancer that cannot be removed by surgery or has spread throughout the body, who have received two or more prior therapies targeting the HER2-protein.
Its main goals are to shrink breast cancer tumors, decrease symptoms, and prevent further spreading.
Enhertu is not a biosimilar agent to trastuzumab, but a unique medication with a different mechanism of action.
Enhertu Treatment for Metastatic Breast Cancer
Enhertu is a treatment regimen for breast cancer that has spread throughout the body, known as metastatic breast cancer.
This medication targets a specific protein on the surface of breast cancer cells called HER-2, which is found in about 20% of breast cancer cases.
Enhertu works by binding to the HER-2 protein, entering the cell, and releasing a molecule called deruxtecan, a type of topoisomerase-I inhibitor that stops breast cancer cells from growing and dividing.
The medication is designed to shrink breast cancer tumors, decrease symptoms of breast cancer, and prevent the cancer from spreading further.
Enhertu is specifically indicated for adults with HER2-positive breast cancer that cannot be removed by surgery or has spread throughout the body, who have received two or more prior therapies targeting the HER2-protein.
This means that Enhertu is not a cure for breast cancer, but rather a treatment to manage the disease and improve quality of life.
When Is Enhertu Used for Breast Cancer?
Enhertu is specifically used to treat adults with breast cancer that has spread to other parts of the body. This type of cancer is known as metastatic.
There are two types of breast cancers that Enhertu can treat: HER2-positive and HER2-low. HER2-positive tumors grow faster due to higher levels of a protein called human epidermal growth factor receptor 2, or HER2. This accounts for 15% to 20% of breast cancers.
HER2-low tumors have some, but not enough, HER2 to be considered positive. This type of cancer was previously classified as HER2-negative, but it's now known that up to 60% of breast cancers are HER2-low.
Enhertu is also used for unresectable breast cancer, which means it can't be removed surgically. In addition, Enhertu is used for metastatic breast cancer that has spread to other parts of the body.
To be eligible for Enhertu, people must have already received other treatments, such as anti-HER2 treatment for HER2-positive cancer or chemotherapy for HER2-low cancer. Alternatively, they must have had a recurrence within 6 months after completing these previous treatments.
