About this study
Official title: Selpercatinib to Enhance RAI Avidity in Children, Adolescents, and Young Adults With Newly Diagnosed Differentiated Thyroid Cancers Harboring RET Fusions
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.
Read the detailed description
This will be an open label, non-randomized study to evaluate the efficacy and safety of the combination of selpercatinib followed by 131I therapy for patients with RET fusion differentiated thyroid cancer. The primary Phase II objective will be to evaluate the pulmonary structural response rate at 18 months to the combination of selpercatinib given for 6-months followed by 131I therapy. This is exempt from Investigational New Drug requirements per the FDA.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Selpercatinib Monotherapy and 131I Therapy in people with Differentiated Thyroid Cancer and Pediatric Cancer, run by Children's Hospital of Philadelphia at 5 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 19 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 24 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Meghan Donnelly, MPH (267-426-9343, 23DT022@chop.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of patients with complete overall, pulmonary, structural, and biochemical response. (time frame: 18 months). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jul 2026.
