Trade Name: Hexalen®
For which conditions is this drug approved?
Altretamine is FDA approved as a single agent for the treatment of ovarian cancer that has stopped responding to previous therapy with a cisplatin and/or alkylating-based chemotherapy regimen.
It is important for patients to remember that physicians have the ability to prescribe medication for conditions other than those for which the drug has been approved by the FDA. Patients who have received a prescription of this drug for a condition other than which it is approved may wish to discuss this issue with their physician.
What is the mechanism of action?
Altretamine produces anti-cancer effects through several possible mechanisms. The most widely accepted explanation of its effects on cancer cells is the fact that it produces a chemical reaction that damages the DNA of a cell. The DNA damage caused by altretamine results in inhibition of cellular growth and/or cellular death.
How is altretamine typically given (administered)?
Altretamine is a capsule that is taken orally. Typically, patients are instructed to take altretamine in divided doses following a meal and at bedtime. Precise doses and scheduling will be determined by a patient’s physician.
How are patients typically monitored?
Patients will usually have scheduled meetings with their healthcare provider while they are being treated with altretamine. Typically, blood will be drawn to check levels of blood cells and to monitor functions of some organ systems, such as the kidneys or liver. Patients may also undergo physical examinations, scans or other measures to assess side effects and response to therapy. Patients may also undergo neurologic assessments, as altretamine may cause damage to the nervous system, although this is uncommon.
What are the most common (occur in 30% or more of patients) side effects of treatment with altretamine?
