Cervical Neoplasms

Brief Summary A Phase II Single-Arm Clinical Trial of Short-Course Radiotherapy Combined with Adebrelimab and Platinum-Based Neoadjuvant Therapy for Locally Advanced Cervical Cancer Background \& Objective: This is a single-center, single-arm, Phase II clinical trial. The primary objective is to evaluate the pathological complete response (pCR) rate (defined as ypT0N0) following neoadjuvant therapy with short-course radiotherapy (SCRT) combined with Adebrelimab (an anti-PD-L1 monoclonal antibody) and single-agent platinum chemotherapy in patients with locally advanced cervical cancer (LACC). Study Design: Patients will receive SCRT followed by three cycles of neoadjuvant chemoimmunotherapy. After completion of neoadjuvant treatment, radical hysterectomy with pelvic lymphadenectomy (with or without para-aortic lymphadenectomy) will be performed. Outcome Measures: Primary Endpoint: Pathological Complete Response (pCR) rate assessed by a central pathologist. Secondary Endpoints: Objective Response Rate (ORR) and R0 resection rate (per RECIST 1.1). Event-Free Survival (EFS) and 2-year EFS rate. Incidence and severity of Treatment-Related Adverse Events (TRAEs, per NCI-CTCAE v5.0) and surgical complications (per Clavien-Dindo classification). Feasibility and implementation rate of different adjuvant treatment strategies based on postoperative risk stratification. Depth of response (major pathological response, MPR). Inclusion Criteria: Key eligibility criteria include: Newly diagnosed, histologically confirmed squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma of the cervix. Clinical stage IB3-IIA2 or IIIA (without parametrial invasion) per FIGO 2018 staging. No evidence of extrapelvic lymph node metastasis or distant metastasis (confirmed by PET/CT or enhanced CT). Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1.

The goal of this clinical trial is to learn if Trastuzumab Rezetecan can treat advanced solid tumors with HER-2 expression in adult participants. The main question it aims to answer is: What is the objective response rate of Trastuzumab Rezetecan in adult patients with HER-2 expressed advanced solid tumors? Participants will receive intravenous infusion of Trastuzumab Rezetecan on Day 1 of each 21-day treatment cycle. The dosage is 4.8 mg/kg per cycle; participants with a body weight of 85 kg or above will receive a fixed dose of 408 mg every 3 weeks.

The goal of this clinical trial is to learn if Zanidatamab can treat HER2-positive advanced tumors in adults. The main question it aims to answer is: What is the objective response rate of Zanidatamab in adult patients with HER-2 positive advanced solid tumors? Participants will receive Zanidatamab intravenously on Day 1 of each 2-week treatment cycle. The dosage is 20 mg/kg per cycle.

This is a phase II trial of combination therapy of cadonilimab(Bispecific Anti-PD-1/CTLA-4 Antibody) plus nab-Paclitaxel in patients with recurrent or metastatic cervical cancer that had failed PD-1/PD-L1 blockade therapy. As a bispecific antibody against PD-1 and CTLA-4, cardonirimab can not only induce the production of a large number of T cells in the early stage of immune response by antagonizing CTLA-4, but also block PD-1 and PD-L1/L2 combination. Thereby restoring the killing function of T cells to tumor cells and reducing the exhaustion of T cells.The hypothesis is the combination of cadonilimab and nab-Paclitaxel will overcome PD-1/PD-L1 blockade-resistance to enhance the response of patients with persistant, recurrent or metastatic cervical cancer.
