Vitrakvi (larotrectinib) is a prescription medicine used to treat certain tumors that are caused by an abnormal "NTRK" gene. Larotrectinib is used when the cancer has spread to other parts of the body or cannot be removed with surgery or other cancer treatments.

Vitrakvi is sometimes given after other cancer treatments did not work or have stopped working.

Vitrakvi was approved by the US Food and Drug Administration (FDA) on an "accelerated" basis. In clinical studies, some people responded to this medicine, but further studies are needed.
