What is Alecensa (alectinib)?
Alecensa (alectinib) is an oral therapeutic for advanced (metastatic) ALK-positive non-small cell lung cancer (NSCLC)1,13,14.
Who is Alecensa (alectinib) for?
Alecensa (alectinib) is indicated for the treatment of people with anaplastic lymphoma kinase (ALK)-positive, metastatic non-small cell lung cancer (NSCLC). It was initially approved as a new option for patients whose disease has worsened after crizotinib or who could not tolerate it in the first place2,10,12,13. (Crizotinib is a drug for ALK-positive NSCLC widely approved, e.g. in USA by the Food and Drug Administration (FDA)2 and in Europe by the European Medical Agency (EMA)3).
Recently the approval has been extended to include the treatment of patients whose disease has not been treated yet (first-line treatment)1,13,14,16.
How does Alecensa (alectinib) work?
Similarly to crizotinib, alectinib is an ALK-inhibitor, which acts by inhibiting the activity of the ALK protein, and may thus prevent ALK-positive NSCLC-cells from growing and spreading2. Crizotinib and alectinib target different mutations of the ALK-gene7; the latter might thus prove effective when the former starts failing. Alectinib’s inhibiting action was observed in ALK gene mutations resistant to crizotinib8. Furthermore, while crizotinib is blocked by the brain’s defensive barrier7,9, alectinib demonstrated its ability to penetrate the central nervous system (CNS, brain and spinal cord) and its shrinking effect on brain metastases7,8.
Approximately 40% of the ALK-positive NSCLC patients develop metastases in their CNS, as an initial site of progression7,8. The ALK (anaplastic lymphoma kinase) gene plays an important role in the development of the brain, and exerts its effects on specific neurons in the nervous system6. Mutations of the ALK gene can occur in several different types of cells, including lung cells, and can result in the development of a tumour2. ALK gene mutations occur in 3 to 7% of patients with NSCLC7.
