What is TKI therapy?
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.
Is TKI therapy chemotherapy?
Any drug used to treat cancer (including tyrosine kinase inhibitors or TKIs) can be considered chemo , but here chemo is used to mean treatment with conventional cytotoxic (cell-killing) drugs that mainly kill cells that are growing and dividing rapidly. Chemo was once one of the main treatments for CML.
What are the side effects of tyrosine kinase inhibitors?
Besides the haematological side effects of most of TKIs like anemia, thrombopenia and neutropenia, the most common extra-heamatologic adverse effects are edema, nausea, hypothyroidism, vomiting and diarrhea .
How do kinase inhibitors work?
A protein kinase inhibitor is a type of enzyme inhibitor that can block the action of protein kinases . Protein kinases add a phosphate group to a protein in a process called phosphorylation, which can turn a protein on or off and therefore affect its level of activity and function.
What is the best drug for CML?
The standard treatment for chronic phase CML is a tyrosine kinase inhibitor ( TKI ) like imatinib ( Gleevec ), nilotinib ( Tasigna ), dasatinib ( Sprycel ), or bosutinib ( Bosulif ). If the first drug stops working or it never really worked well at all, the dose may be increased or another TKI might be tried.
Does imatinib cause hair loss?
It is associated with platelet‐derived growth factor receptor (PDGFR)‐regulated maintenance of the anagen phase of the hair cycle. 1 The hair loss is thought to be related to inhibition of PDGFR by imatinib with resulting telonization of the hair follicles that eventually led to telogen effluvium.
Can CML be cured completely?
A stem cell or bone marrow transplant is the only potential cure for CML , but it’s a very intensive treatment and is not suitable for many people with the condition.
Can you drink alcohol while taking Tasigna?
However, Tasigna and alcohol can each cause liver problems when used alone. Drinking alcohol while you ‘re taking Tasigna could further increase your risk of liver damage. Talk with your doctor about whether it’s safe for you to drink alcohol during Tasigna treatment.
What is chronic myeloid Leukaemia?
Chronic myeloid leukaemia ( CML ) is a type of cancer that affects the white blood cells and tends to progress slowly over many years. It can occur at any age, but is most common in older adults around 60-65 years of age.
What does tyrosine do to the body?
Tyrosine is a popular dietary supplement used to improve alertness, attention and focus. It produces important brain chemicals that help nerve cells communicate and may even regulate mood ( 1 ).
What does a tyrosine kinase do?
Tyrosine kinases are important mediators of this signal transduction process, leading to cell proliferation, differentiation, migration, metabolism and programmed cell death. Tyrosine kinases are a family of enzymes, which catalyzes phosphorylation of select tyrosine residues in target proteins , using ATP.
What does a kinase do?
Protein kinases (PTKs) are enzymes that regulate the biological activity of proteins by phosphorylation of specific amino acids with ATP as the source of phosphate, thereby inducing a conformational change from an inactive to an active form of the protein.
What does protein kinase A?
Protein kinases (PTKs) are enzymes that regulate the biological activity of proteins by phosphorylation of specific amino acids with ATP as the source of phosphate, thereby inducing a conformational change from an inactive to an active form of the protein .
Which drugs are protein kinase inhibitors?
|Gefitinib||EGFR||2003 non-small cell lung cancer (NSCLC)|
|Imatinib||Bcr-Abl||2001 (CML), 2002 (GIST)|
|Lapatinib||EGFR/ErbB2||2007 (HER2+ Breast)|
Why are kinases good drug targets?
Protein kinases are major drug targets for oncology. The large size of the kinome, active site conservation and the influence of activation states on drug binding complicates the analysis of their cellular mode of action.
