Class: Biological Therapy
Generic Name: brigatinib
Trade Name: Alunbrig®
For which conditions is Alunbrig approved for? Alunbrig is approved for the treatment of patients with metastatic non-small cell lung cancer (NSCLC) that is caused by a defect in a gene called ALK (anaplastic lymphoma kinase) whose disease has worsened after taking Xalkori® (crizotinib) or cannot tolerate Xalkori.
What is the mechanism of action? Alunbrig is a kinase inhibitor. These drugs work by blocking the action of enzymes called kinases, which are involved in many cell functions, including cell signaling, growth, and division. These enzymes may be too active or found at high levels in some types of cancer cells, and blocking them may help keep cancer cells from growing. Specifically, Alunbrig targets ALK.
How is Alunbrig typically given (administered)? Alunbrig is given orally (capsule) once daily until disease progression or unacceptable side effects. A lower dose is given for the first 7 days of treatment and if well tolerated, then a higher dose is prescribed.
How are patients typically monitored? Alunbrig can cause complications involving the lungs, heart, eyes, pancreas, blood sugar and muscles. Respiratory symptoms, blood pressure, heart rate, CPK levels, pancreatic enzyme levels, and blood sugar are checked regularly.
