Generic and specialty pharmaceuticals company Mylan has launched its Fulvestrant Injection, a 250mg/5mL (50 mg/mL) per single-dose prefilled syringe, a generic version of AstraZeneca’s Faslodex Injection, in the US.

Fulvestrant is used in treatment of definite advanced breast cancer in women who have experienced menopause as monotherapy and in advanced or metastatic breast cancer in combination with other products.

Mylan has secured approval for its Abbreviated New Drug Application (ANDA) for the product from the US Food and Drug Administration (FDA).

Mylan president Rajiv Malik said: “Mylan’s launch of Fulvestrant Injection represents an important addition to our growing oncology portfolio and, more importantly, expands the available treatment options for women who are facing advanced or metastatic stages of breast cancer.

“The launch also reinforces our scientific expertise in bringing to market complex products, like injectables, which further enhances our institutional business and exemplifies our continued commitment to expanding access to medicine.”

Mylan said that its Fulvestrant Injection is indicated as prescription medicine to treat women with Hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced breast cancer or metastatic breast cancer.
