FDA Grants Full Approval for DepoCyt(R) for the Treatment of Lymphomatous MeningitisBRIDGEWATER, N.J.--(HSMN NewsFeed)--Enzon Pharmaceuticals, Inc. (Nasdaq: ENZN ) today announced that the US Food and Drug Administration (FDA) has granted full approval for DepoCyt® (cytarabine liposome injection) for the treatment of patients with lymphomatous meningitis, a life-threatening complication of lymphoma. DepoCyt was originally approved under the Accelerated Approval regulations of Subpart H of the Food, Drug and Cosmetic Act, based on a preliminary demonstration of an increased complete response rate compared to unencapsulated cytarabine.
The full approval was based on findings from two randomized controlled clinical trials that included over 200 patients with neoplastic meningitis related to solid tumors, lymphoma or leukemia. The first study demonstrated that more patients with lymphomatous meningitis treated with DepoCyt showed an absence of neurological progression of the disease. The second study showed an increase in complete cytologic responses among patients treated with DepoCyt, as defined by a clearing of malignant cells in the cerebrospinal fluid (CSF).
"The FDA's full approval of DepoCyt is an important milestone for this unique product that has benefited those suffering from this devastating complication of cancer since its introduction to the market in 1999," said Jeffrey H. Buchalter, Chairman and Chief Executive Officer of Enzon. "Furthermore, we are pleased all of the FDA requirements have been met and we can continue to make this product available to the patients who need it."
DepoCyt is manufactured by SkyePharma Inc.
DepoCyt is a sustained release formulation of the chemotherapeutic agent, cytarabine, used for the treatment of patients with lymphomatous meningitis. Lymphomatous meningitis can be controlled with cytarabine, but because of the drug's short half-life, a spinal injection is required twice per week, whereas DepoCyt is dosed once every two weeks. DepoCyt gradually releases cytarabine into the cerebral spinal fluid resulting in a significantly extended half-life, prolonged exposure to the therapy, and a more uniform distribution.
Important safety information
DepoCyt® (cytarabine liposome injection) should be administered only under the supervision of a qualified physician experienced in the use of intrathecal cancer chemotherapeutic agents. Appropriate management of complications is possible only when adequate diagnostic and treatment facilities are readily available. In all clinical studies, chemical arachnoiditis, a syndrome manifested primarily by nausea, vomiting, headache and fever, was a common adverse event. If left untreated, chemical arachnoiditis may be fatal. The incidence and severity of chemical arachnoiditis can be reduced by coadministration of dexamethasone. Patients receiving DepoCyt should be treated concurrently with dexamethasone to mitigate the symptoms of chemical arachnoiditis.
About Lymphomatous Meningitis
Lymphomatous meningitis is a complication of lymphoma that is characterized by the spread of the cancer to the central nervous system and the formation of secondary tumors within the thin membranes surrounding the brain. Symptoms can include numbness or weakness in the extremities, pain, sensory loss, double-vision or loss of vision, hearings problems, and headaches.
