Study of Sinibolimab Combined with Lenvatinib As Neoadjuvant Therapy for Locally Advanced Unresectable Differentiated Thyroid Carcinoma
China20 participantsStarted 2025-03-01
Plain-language summary
This study is a single-arm, prospective investigation aimed at evaluating the efficacy of Sinibolimab combined with Lenvatinib as neoadjuvant therapy for locally advanced unresectable differentiated thyroid carcinoma in a Phase II clinical trial. The study plans to enroll 20 patients with locally advanced unresectable papillary thyroid carcinoma. Eligible participants will receive a combination of Sinibolimab and Lenvatinib for four cycles. After completing the four cycles of treatment, the tumor response will be assessed to determine the feasibility of surgical intervention. Participants who complete treatment will enter a follow-up period for safety monitoring and survival assessment. The primary endpoints of the study include the major pathological response (MPR) and the R0/R1 resection rate. Secondary endpoints include the objective response rate (ORR) after four cycles, 1-year and 2-year disease-free survival (DFS) rates, serious adverse events (SAE), and immune-related adverse events (irAE).

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Histologically confirmed newly diagnosed or recurrent locally advanced (T4N1M0) differentiated thyroid carcinoma with an estimated risk of R2 resection.
Performance Status (PS) score of 0-1. Age ≥ 18 years. Measurable lesions according to RECIST 1.1 criteria. Normal function of major organ systems.
Exclusion Criteria:
* Intratracheal airway tumors. Complete carotid artery encasement/invasion. Full-thickness infiltration of the esophageal wall. Arterial thrombosis/cancer thrombus. Active hemoptysis (bright red blood ≥ 1/2 teaspoon) or other uncontrolled bleeding within 21 days prior to study enrollment.
History of prior neck radiotherapy. Previous treatment with Lenvatinib or immunotherapy. Participants with \> 1+ proteinuria on urine dipstick will undergo 24-hour urine collection for quantitative assessment of proteinuria. Participants with urine protein ≥ 1g/24 hours will be ineligible.
Active, known, or suspected autoimmune diseases. Participants requiring long-term systemic corticosteroid therapy. Participants using bronchodilators, inhaled corticosteroids intermittently due to COPD or asthma, or those receiving local corticosteroid injections may be eligible.
Active unstable angina and/or congestive heart failure. New-onset myocardial infarction within the last 6 months.
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?

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?
