Larotrectinib to Enhance RAI Avidity in Differentiated Thyroid Cancer
NCT05783323
Recruiting
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.
