Official title
Larotrectinib to Enhance RAI Avidity in Patients With Differentiated Thyroid Cancer Harboring NTRK Fusions (LANTERN)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Papillary thyroid cancer (PTC) is the most common form of differentiated thyroid cancer (DTC). The traditional first line treatment for patients with advanced DTC after surgical resection is radioactive iodine (RAI) therapy. However, less than a quarter of patients with lung metastases will achieve a complete response to RAI therapy, and this therapy carries the risk of pulmonary fibrosis and an increasingly recognized risk of secondary malignancies.
