Generic Name: cytarabine liposome injection (sigh-TARE-a-been lip-oh-ZOE-mel)
Trade Name: Depocyt®
For which conditions is this drug approved? Depocyt is indicated for the intrathecal treatment of lymphomatous meningitis, which is lymphoma that is present in the meninges (lining of the brain and spinal cord). Depocyt has been formulated to produce a sustained release of the chemotherapy agent cytarabine.
What is the mechanism of action? Depocyt belongs to a group of drugs called antimetabolites. Depocyt produces its anti-cancer effects by inhibiting the ability of a cell to produce DNA or repair DNA. By inhibiting the production and repair of DNA, Depocyt suppresses the ability of a cell to replicate or repair itself, ultimately causing cellular death.
How is Depocyt typically given (administered)? Depocyt may be delivered into the spinal fluid through intrathecal or intraventricular administration. Intrathecal administration is the direct placement of the drug into the spinal fluid through a spinal tap procedure. Intraventricular administration involves the placement of a small “reservoir”, called an ommaya reservoir, directly under the skin in the scalp. There is a catheter that runs from the ommaya reservoir to the outer part of the brain. Depocyt is placed into the ommaya reservoir, where the agent travels through the catheter to the outer part of the brain. Patients typically receive steroids prior to and following Depocyt to reduce inflammation of the meninges that can be caused by treatment. The route, dose and scheduling in which Depocyt is administered is dependent upon many factors, including the condition being treated, the particular treatment regimen being utilized, overall health, and the patient’s tolerance of therapy.
How are patients typically monitored? Patients will usually have scheduled meetings with their healthcare provider while they are being treated with Depocyt. Typically, blood will be drawn to check levels of blood cells and to monitor functions of some organ systems, as well as electrolyte and metabolic product levels. Physical examinations, scans, or other measures may also be utilized to assess side effects and response to therapy. Patients will be monitored for inflammation of the meninges, including pain or rigidity of the neck, nausea and vomiting, fever, headache and back pain. If patients experience these symptoms, they should contact their healthcare provider.
