Effect of Compound Kushen Injection Combined With Pabolizumab in the Treatment of Cervical Adenocarcinoma

• Status: Not yet recruiting
• Trial end date: 2025-12-31
• Target enrollment: 0
• Participant gender: Female

Summary

In the past few decades, the incidence of endocervical adenocarcinomas (ECAs) has been on the rise both in absolute numbers and overall proportion in cervical cancers. ECAs remain a significant public health problem despite advances in treatment options. Patients with ECA have a poorer survival rate than patients with squamous cell carcinoma (SCC), especially in patients with metastatic tumors. In the newly published 2020 World Health Organization (WHO) Classification of Female Genital Tumors, ECAs are subclassified into human papillomavirus-associated (HPVA) and human papillomavirus-independent (HPVI) groups. Meanwhile, PD-1/PD-L1 immunotherapy has been approved for the treatment of advanced cervical cancer, but there are still many deficiencies. Therefore, we plan to use the new classification of female genital tumors and conduct a clinical trial to explore the safety and effectiveness of compound kushen injection combined with pabolizumab in the treatment of metastatic, recurrent, persistent cervical adenocarcinoma.

Sign written informed consent before conducting any research-related procedures.

Exclusion Criteria:

1. People who are known to be allergic to compound kushen injection and pabolizumab or to active or inactive ingredients of drugs with similar chemical structures to compound kushen injection and pabolizumab.

2. Symptomatic, uncontrolled brain metastases or pia meningeal metastases.

3. No imaging scan is required to confirm brain-free metastases; patients with spinal cord compression may still be considered if they have received targeted treatment and have evidence of clinical stability of the disease for at least> 28 days (controlled central nervous system metastasis must be in the study Have received treatment such as radiation or chemotherapy for at least 1 month; patients must not have new symptoms related to central nervous system lesions or symptoms that indicate disease progression, and patients either take a stable dose of hormones or do not need to take hormones).

4. Underwent major surgery within 3 weeks before the study began, or any surgical effects that have not recovered after surgery, or received chemotherapy.

5. Received> 20% bone marrow palliative radiotherapy 1 week before enrollment.

6. Have aggressive cancers other than cervical cancer (except fully treated basal or squamous cell skin cancer within 2 years before enrollment).

8. Suffering from a serious or uncontrolled illness, including but not limited to:

1. Uncontrollable nausea and vomiting, inability to swallow research drugs, and any gastrointestinal disorders that may interfere with the metabolism of the drug.

2. Active viral infections such as human immunodeficiency virus, hepatitis B, hepatitis C, etc.

3. Uncontrolled major seizures, unstable spinal cord compression, superior vena cava syndrome, or other mental illnesses that prevent patients from signing informed consent.

9. History of bleeding and thrombosis:

1. Any CTCAE Grade 2 bleeding event within 3 months prior to screening, or CTCAE Grade 3 and above bleeding events within 6 months prior to screening.

3. Have active bleeding or coagulopathy, have a tendency to bleed, or are receiving thrombolytic or anticoagulant therapy.
