Italy25 participantsStarted 2024-12-20
Plain-language summary
This window of opportunity trial is studying a checkpoint inhibitor agent to treat differentiated thyroid cancer in a neoadjuvant setting. A checkpoint inhibitor is a compound aimed at restoring tumor immunosurveillance. The name of this agent is pembrolizumab.

Inclusion criteria
. Male/female participants who are at least 18 years of age on the day of signing informed consent with histologically confirmed diagnosis of differentiated thyroid carcinoma candidate to surgery not previously treated will be enrolled in this study.
. Patients with a risk \> 20% for persistent/recurrent disease: primary tumor \> 4 cm; multifocal papillary microcarcinoma with extra tumor extension (ETE) and known BRAF V600E mutation; clinical N1; gross ETE (macroscopic invasion of perithyroidal soft tissues); extranodal extension; expected incomplete tumour resection.
. The participant (or legally acceptable representative if applicable) provides written informed consent for the trial.
. Have measurable disease based on RECIST 1.1.
. Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1. Evaluation of ECOG is to be performed within 7 days prior to the date of allocation/randomization.
. Have adequate organ function as defined in the following table (Table 2) Specimens must be collected within 10 days prior to the start of study treatment.
Exclusion criteria
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
To investigate the behavior of exhausted cytotoxic T cell (CD8+ T) in tumor tissue in response to pembrolizumab
Timeframe: Up to 12 months after surgery
2
To investigate the behavior of exhausted cytotoxic T cell (CD8+ T) at circulating level in response to pembrolizumab
. A WOCBP who has a positive urine pregnancy test within 72 hours prior to randomization. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
. Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (eg, CTLA-4, OX-40, CD137).
. Has received prior systemic anti-cancer therapy including investigational agents within 4 weeks prior to randomization.
. Has received prior radiotherapy within 2 weeks of start of study intervention. Participants must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis. A 1-week washout is permitted for palliative radiation (≤2 weeks of radiotherapy) to non-CNS disease.
. Has received a live vaccine within 30 days prior to the first dose of study drug. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette-Guérin (BCG), and typhoid vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (eg, FluMist®) are live attenuated vaccines and are not allowed. Administration of killed vaccines is allowed.
. Is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to the first dose of study intervention.
. Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior to the first dose of study drug.
. Has a history of a second malignancy, unless potentially curative treatment has been completed with no evidence of malignancy for 2 years. The time requirement does not apply to participants who underwent successful definitive resection of basal cell carcinoma of the skin, squamous cell carcinoma of the skin, superficial bladder cancer, in situ cervical cancer, or other in-situ (eg, breast carcinoma or cervical cancer in situ that have undergone potentially curative therapy are not excluded).
