June 7, 2009
Brand Name: Proleukin
Aldesleukin is a synthetic form of interleukin-2 (IL-2), which is a substance the body produces to stimulate the growth of certain disease-fighting blood cells in the immune system. Aldesleukin, also known as Proleukin, belongs to the class of medicines called biological response modifiers. Biological response modifiers stimulate the body's response to infection and disease. Aldesleukin also belongs to the class of medicines called antineoplastics. Antineoplastics slow or stop the growth of cancer cells.
Aldesleukin is being studied in clinical trials to see if it can improve the body's immune response and slow the progress of HIV. This medicine does not cure or prevent HIV infection or AIDS and does not reduce the risk of passing the virus to other people. Aldesleukin is approved by the FDA for the treatment of kidney and skin cancers.
Aldesleukin comes in liquid form that is given by injection into a vein or under the skin. In clinical trials, aldesleukin is usually given in small doses that are injected under the skin or slowly into the bloodstream.When aldesleukin is used to treat kidney cancer or skin cancer, it is given in high doses that are injected into the bloodstream very quickly. Because this form of aldesleukin therapy can have very serious side effects that are sometimes fatal, it is usually given in the hospital or under the close supervision of a doctor or nurse.
Individuals should tell a doctor about any medical problems before taking this medicine.
