About Halaven
Overview
Halaven contains eribulin mesylate, a cancer medicine given into a vein. It treats breast cancer that has spread after at least two chemotherapy regimens for metastatic disease, with prior treatment including an anthracycline and a taxane. It also treats liposarcoma that cannot be removed by surgery or has spread, after prior chemotherapy containing an anthracycline. It works by blocking the growth of structures called microtubules that cells need to divide, leading to cell death.
What it treats
- Metastatic breast cancer after at least two chemotherapy regimens for metastatic disease. Previous treatment must have included an anthracycline and a taxane, either as treatment after surgery or for metastatic disease. - Liposarcoma that cannot be removed by surgery or has spread to other parts of the body, after previous treatment with an anthracycline-containing regimen.
Safety information
Side effects
Common side effects include tiredness or weakness, nausea, hair loss, constipation, and peripheral neuropathy (nerve problems). Low white blood cell counts (neutropenia) and low red blood cell counts (anemia) were also common in patients with metastatic breast cancer. Abdominal pain and fever were also common in patients with liposarcoma or leiomyosarcoma. Serious effects that warrant contacting your doctor include low white blood cell counts, nerve problems, and changes in the heart’s electrical activity called QT prolongation. Severe reductions in white blood cells, potassium, and calcium were reported in patients with liposarcoma or leiomyosarcoma. Your doctor will monitor blood cell counts and nerve problems; heart monitoring is needed in patients with certain heart conditions, electrolyte abnormalities, or medicines that prolong the QT interval. Eribulin should be avoided in people with congenital long QT syndrome. Eribulin can harm an unborn baby. Contact your doctor if you become pregnant, and use effective contraception if you could become pregnant.
When to call your doctor
If symptoms are severe or getting worse quickly, seek emergency care rather than waiting.
Before taking this medicine
The label lists no formal contraindications. However, eribulin mesylate should be avoided in people with congenital long QT syndrome. Caution and monitoring are needed for: - Low neutrophil counts: blood cell counts should be monitored. - Peripheral neuropathy: monitor for signs of nerve problems. - Heart failure, slow or irregular heart rhythms, use of medicines that prolong the QT interval, or electrolyte abnormalities: monitoring for QT prolongation is recommended. - Liver or kidney impairment: treatment may need adjustment by the prescriber. Severe liver impairment has not been studied. Eribulin mesylate can harm an unborn baby. Women who could become pregnant should use effective contraception. Do not breastfeed during treatment.
