Use in Cancer
Larotrectinib sulfate is approved to treat:
- Solid tumors that have an NTRK gene fusion without a drug-resistance mutation in certain TRK proteins. It is used in adults and children whose cancer has metastasized (spread to other parts of the body) or cannot be removed by surgery and has gotten worse after other treatment or cannot be treated with other therapies.
This use is approved under FDA’s Accelerated Approval Program. As a condition of approval, a confirmatory trial(s) must show that larotrectinib sulfate provides a clinical benefit in these patients.
Larotrectinib sulfate is also being studied in the treatment of other types of cancer.
