Is imatinib a targeted therapy?

Is imatinib a targeted therapy?

Imatinib, an oral targeted therapy, inhibits tyrosine kinases specifically BCR-ABL, c-KIT, and PDGFRA. Apart from its remarkable success in CML and GIST, Imatinib benefits various other tumors caused by Imatinib-specific abnormalities of PDGFR and c-KIT.

What protein does imatinib target?

Imatinib mesylate (Gleevec) is a drug unique for the treatment of certain forms of cancer. It works by targeting, and turning off, specific tyrosine kinase proteins that cause the uncontrolled cell growth and the inhibition of apoptosis in cancer cells.

How does Gleevec target cancer cells?

Gleevec, known generically as imatinib, works by slowing or stopping the growth of certain cancer cells. Gleevec inhibits (or blocks) specific enzymes in the body called tyrosine kinases. Tyrosine kinase enzymes are involved in many cell functions, including cell signaling (communication), growth, and division.

Is imatinib an immunosuppressant?

The drug does so by stimulating the bone marrow to make more neutrophils and macrophages, immune cells that are important for resisting bacterial infection. “This was surprising because there are reports that imatinib can be immunosuppressive in some patients,” Kalman says.

Is imatinib an immunotherapy?

Immunotherapy with monoclonal antibodies, such as ipilimumab, may help the body’s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Imatinib mesylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Is imatinib a biologic?

Imatinib is a targeted cancer drug (biological therapy) and is also known by its brand name Glivec (pronounced glee-vec). It is a treatment for many different types of cancer.

What is TKI treatment?

Tyrosine kinase inhibitors (TKIs) are a type of targeted therapy. TKIs come as pills, taken orally. A targeted therapy identifies and attacks specific types of cancer cells while causing less damage to normal cells.

Does imatinib resemble ATP?

4.9. 1 Compounds Acting as ATP Mimics. Imatinib (STI-571, from signal transduction inhibitor; Glivec®) was the first protein kinase inhibitor to be approved as a cancer treatment. After a particularly rapid clinical development, it was approved in 2001 for patients with Philadelphia chromosome-positive CML.

What type of cancer does Gleevec target?

NCI-supported research led to a series of discoveries that resulted in the development of imatinib (Gleevec), a landmark drug that has vastly improved the outcomes of patients with a type of blood cancer called chronic myelogenous leukemia.

Why is Gleevec so significant?

In particular, the discovery and development of Gleevec taught scientists that by understanding the biology of a disease, it is possible to learn how to treat or cure that disease.

What is im imatinib used to treat?

Imatinib is specific tyrosine kinase receptor inhibitor that is used in the therapy of Philadelphia chromosome-positive chronic myelogenous leukemia and gastrointestinal stromal tumors, both of which are marked by an abnormal, constitutively expressed tyrosine kinase that causes unregulated cell growth.

Is imatinib a kinase inhibitor or inhibitor?

Imatinib is a Kinase Inhibitor. The mechanism of action of imatinib is as a Protein Kinase Inhibitor. Imatinib is an antineoplastic agent that inhibits the Bcr-Abl fusion protein tyrosine kinase, an abnormal enzyme produced by chronic myeloid leukemia cells that contain the Philadelphia chromosome.

What is im imatinib (Gleevec)?

Imatinib (also known as “Gleevec” or “Glivec”), a tyrosine kinase inhibitor, was called as “magical bullet,” when it revolutionized the treatment of chronic myeloid leukemia (CML) in 2001.

Where can I find more information about imatinib mesylate?

FDA label information for this drug is available at DailyMed. Imatinib mesylate is approved to treat: Acute lymphoblastic leukemia in adults and children that is Philadelphia chromosome positive. In adults, it is used for disease that has recurred (come back) or is refractory (does not respond to treatment).
