AZD-9291 Powder Description
AZD-9291 powder is a targeted therapy that targets the mutated epidermal growth factor receptor (EGFR) T790M within the cancer cell.
The EGFR gene plays an important role in both normal and cancer cells. This gene leads to the production of EGFR protein. This protein is normally part of a chain of molecules that relay a signal that tells cells how to grow and divide. A change in the EGFR gene (called a mutation) can alter the way that the EGFR protein works. Instead of waiting for its turn to signal a cell to divide or grow, the EGFR protein is out of control and signals all of the time, this out of control EGFR signaling may drive the uncontrolled growth of cancer cells. AZD-9291 powder targets select mutant forms of EGFR, including t790M, L858R and exon 19-deletion. AZD-9291 powder is selective for sensitizing mutations and the T790M resistance mutation, which is the most common mechanism of resistance to EGFR tyrosine kinase inhibitors.
AZD-9291 Powder Mechanism of Action
AZD-9291 powder is an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) that binds to certain mutant forms of EGFR (T790M, L858R, and exon 19 deletion) that predominate in non-small cell lung cancer (NSCLC) tumours following treatment with first-line EGFR-TKIs. As a third-generation tyrosine kinase inhibitor, AZD-9291 powder is specific for the gate-keeper T790M mutation which increases ATP binding activity to EGFR and results in poor prognosis for late-stage disease. Furthermore, AZD-9291 powder(osimertinib) has been shown to spare wild-type EGFR during therapy, thereby reducing non-specific binding and limiting toxicity.
AZD-9291 Powder Application
AZD-9291 powder is a prescription medicine for non-small cell lung cancer (NSCLC) that has spread to other parts of the body (metastatic). AZD9291 is used:
▪ As your first treatment if tumors have a certain abnormal epidermal growth factor receptor (EGFR) gene(s).
▪ If you have a certain type of EGFR gene and were previously treated with an EGFR tyrosine kinase inhibitor (TKI) medicine that did not work or is no longer working.
AZD-9291 Powder Side Effects & Warning
AZD-9291 powder may cause serious side effects, including:
▲ lung problems. AZD-9291 powder may cause lung problems that may lead to death. Symptoms may be similar to symptoms from lung cancer. Tell your doctor right away if you have any new or worsening lung symptoms, including trouble breathing, shortness of breath, cough, or fever
▲ heart problems, including heart failure. AZD-9291 powder may cause heart problems that may lead to death. Your doctor should check your heart function before you start taking AZD-9291 powder and during treatment as needed. Tell your doctor right away if you have any of the following signs and symptoms of a heart problem: feeling like your heart is pounding or racing, shortness of breath, swelling of your ankles and feet, feeling lightheaded
▲ eye problems. AZD-9291 powder may cause eye problems. Tell your doctor right away if you have symptoms of eye problems which may include watery eyes, sensitivity to light, eye pain, eye redness, or vision changes. Your doctor may send you to see an eye specialist (ophthalmologist) if you get eye problems with AZD-9291 powder.
▲ skin problems. AZD-9291 powder may cause skin problems. Tell your doctor right away if you develop target lesions (skin reactions that look like rings), severe blistering or peeling of the skin
The most common side effects of AZD-9291 powder are:
▪ dry skin
▪ changes in your nails, including: redness, tenderness, pain, inflammation, brittleness, separation from nailbed, and shedding of nails
▪ mouth sores
▪ decreased appetite
These are not all the possible side effects of AZD-9291 powder. For more information, ask your doctor or pharmacist.
