About Halaven^® (eribulin mesylate) Injection
Halaven, the first agent in the halichondrin class, is indicated for patients with metastatic breast cancer who have received at least two chemotherapeutic regimens for the treatment of metastatic breast cancer. Prior therapy should have included an anthracycline and a taxane in either the adjuvant or metastatic setting. Halaven is a synthetic analog of halichondrin B, a natural product that was isolated from the marine sponge Halichondria okadai.

Important Safety Information

Neutropenia

Monitor complete blood counts prior to each dose, and increase the frequency of monitoring in patients who develop Grade 3 or 4 cytopenias. Delay administration and reduce subsequent doses in patients who experience febrile neutropenia or Grade 4 neutropenia lasting longer than 7 days
Severe neutropenia (ANC <500/mm3) lasting more than 1 week occurred in 12% (62/503) of patients. Patients with elevated liver enzymes >3 × ULN and bilirubin >1.5 × ULN experienced a higher incidence of Grade 4 neutropenia and febrile neutropenia than patients with normal levels
Grade 3 and Grade 4 neutropenia occurred in 28% and 29%, respectively, of patients who received Halaven. Febrile neutropenia occurred in 5% of patients and two patients (0.4%) died from complications

Peripheral Neuropathy

Patients should be monitored closely for signs of peripheral motor and sensory neuropathy
Grade 3 peripheral neuropathy occurred in 8% of patients, and Grade 4 in 0.4% of patients who received Halaven. Delay administration of Halaven until resolution to Grade 2 or less
Neuropathy lasting more than 1 year occurred in 5% of patients. Twenty-two percent of patients developed a new or worsening neuropathy that had not recovered within a median follow-up duration of 269 days (range 25-662 days)
Peripheral neuropathy (5%) was the most common adverse reaction resulting in discontinuation

Pregnancy Category D

Halaven is expected to cause fetal harm when administered to a pregnant woman and patients should be advised of these risks

QT Prolongation

In an uncontrolled ECG study in 26 patients, QT prolongation was observed on Day 8, independent of Halaven concentration, with no prolongation on Day 1. ECG monitoring is recommended for patients with congestive heart failure; bradyarrhythmias; concomitant use of drugs that prolong QT interval, including Class Ia and III antiarrhythmics; and electrolyte abnormalities
Correct hypokalemia or hypomagnesemia prior to initiating Halaven^® and monitor electrolytes periodically during therapy. Avoid in patients with congenital long QT syndrome

Hepatic and Renal Impairment

For patients with mild (Child-Pugh A) or moderate (Child-Pugh B) hepatic and/or moderate or severe (CrCl 15-49 mL/min) renal impairment, a reduction in starting dose is recommended

Most Common Adverse Reactions

Most common adverse reactions (>25%) reported in patients receiving Halaven were neutropenia (82%), anemia (58%), asthenia/fatigue (54%), alopecia (45%), peripheral neuropathy (35%), nausea (35%), and constipation (25%)
The most common serious adverse reactions reported in patients receiving Halaven were febrile neutropenia (4%) and neutropenia (2%)
