What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 14 participants in total. It began in 2024-07-24 with a primary completion date of 2025-05-31.

Brief Summary

This study is a single-arm intervention study. Locally advanced differentiated thyroid carcinoma patients receive neoadjuvant therapy with Donafenib and PD-1 antibody Sintilimab and those who can undergo surgery after neoadjuvant therapy receive surgical treatment. The aim of the study is to evaluate the efficacy and safety of Donafenib combined with PD-1 antibody in neoadjuvant therapy of locally advanced thyroid cancer.

Eligibility Criteria

Locally advanced DTC is defined as meeting at least one of the criteria: surgery is expected to be difficult to complete R0/R1 resection; AJCC defined T4 stage: any size of tumor infiltrating beyond the thyroid capsule to the subcutaneous soft tissue, throat, trachea, esophagus, recurrent laryngeal nerve, tumor invades the prevertebral fascia or surrounds the carotid or mediastinal vessels. 5.

Within the first 5 years of randomization, cancer with a different primary site or histological type from thyroid cancer, or cancer coexisting with thyroid cancer but with a different primary site or histological type, except for cervical carcinoma in situ, treated basal cell carcinoma, and superficial bladder tumors (non-invasive tumors, carcinoma in situ, and tumor invasion of the lamina propria); 5. Previous or current congenital or acquired immunodeficiency disease; 6. Active or previously documented autoimmune disease or inflammatory disease (including but not limited to: autoimmune hepatitis, interstitial pneumonia, inflammatory bowel disease, systemic lupus erythematosus, vasculitis, uveitis, Hypophysitis, hyperthyroidism or hypothyroidism, asthma requiring bronchodilator treatment, etc.), patients with vitiligo or asthma that has been completely resolved in childhood, without any intervention in adulthood can be included; 7. Have a history of severe mental illness in the past; 8.
