Neoadjuvant Adebrelimab Plus CRT for Locally Advanced Thymic Carcinoma

Starting soon · Phase 2

Conditions studied: Thymic Carcinoma

In brief

The goal of this clinical trial (Phase II) is to evaluate the efficacy and safety of neoadjuvant Adebrelimab combined with chemoradiation in patients with locally advanced thymic carcinoma. The main questions it aims to answer are: * Is neoadjuvant therapy with Adebrelimab plus chemoradiation effective? * Is this combination treatment safe and tolerable in this patient population? Participants will: * Receive 2-4 cycles of neoadjuvant Adebrelimab combined with a platinum-based chemotherapy regimen (such as carboplatin plus paclitaxel) and concurrent radiotherapy prior to surgery. * Undergo re-staging imaging to assess tumor response and determine surgical candidacy. * Undergo surgical resection if the tumor is resectable after neoadjuvant treatment. * Receive adjuvant Adebrelimab therapy for up to one year following surgery. * Undergo regular follow-up visits for safety monitoring and survival assessment.

You may qualify if…

Age ≥ 18 and ≤ 75 years old at the time of signing the informed consent form, both male and female are eligible.
Histologically confirmed thymic carcinoma.
Potentially resectable locally advanced (T3/4NxM0). No previous treatment for thymic carcinoma, including but not limited to surgery, local radiotherapy, chemotherapy, immunotherapy, targeted drug therapy, and other investigational drug therapy.
At least one measurable lesion according to RECIST 1.1 criteria.
ECOG PS score: 0-1.
Expected survival ≥ 3 months.
Important organ functions must meet the following standards:
Blood routine test: (No blood transfusion or use of G-CSF and other cytokine drugs for correction within 2 weeks before screening);
Hemoglobin (HB) ≥ 90 g/L;
Absolute neutrophil count (ANC) ≥ 1.5×109/L;
Platelet count (PLT) ≥ 90×109/L;

Patients with asthma requiring medical intervention with bronchodilators cannot be included.
Patients with active pulmonary tuberculosis. Those who have received adequate treatment and have stopped anti-tuberculosis treatment for at least 3 months before treatment can be enrolled.
