Class: Biological Therapy

Generic Name: alectinib

Trade Name: Alecensa®

For which conditions is this drug approved? Alecensa is approved to treat patients with non-small cell lung cancer (NSCLC) that has a mutation in the anaplastic lymphoma kinase (ALK) gene and has spread to other parts of the body. Alecensa is also approved for patients who have taken the medicine Xalkori® (crizotinib), but their NSCLC has gotten worse or they cannot tolerate Xalkori.

What is the mechanism of action? Alecensa is thought to work by blocking the activity of the ALK protein. Blocking the ALK protein may prevent NSCLC cells from growing and spreading.
