Cadonilimab Plus Anlotinib for R/M/P Cervical Cancer

Phase 2

Recruiting

• Conditions: Cervical Cancer
• Interventions: Drug: Cadonilimab; Drug: Anlotinib; Drug: Granulocyte-Macrophage Colony-Stimulating Factor

• Registration Number: NCT05817214
• Lead Sponsor: Zhongnan Hospital

Brief Summary

The goal of this clinical trial is to test a new treatment combination including cadonilimab, anlotinib and granulocyte-macrophage colony-stimulating factor (GM-CSF) in recurrent, metastasis and persistent cervical cancer. The main questions it aims to answer are:

* The efficacy of this combination in R/M/P CC;

* The tolerance of this combination in R/M/P CC;

* Possible biomarker of treatment response for this combination.

Participants will receive cadonilimab of 10mg/kg every three weeks at day 1, take anlotinib (12mg) orally in day 1 to day 14, then take a 7 days break and subcutaneously injection of GM-CSF (200ug) from day 1 to day 14, then also take a 7-days break. This treatment will continue until progression or intolerable toxicity or withdraw of participants and it will last for no longer than 2 years.

Detailed Description

The prognosis was poor for recurrent, metastasis and persistent cervical cancer especially for those who had multiple lesions and history of previous radiation therapy. KEYNOTE-826 Study demonstrated survival benefit of adding pembrolizumab into the standard first-line treatment for cervical cancer. Here we designed a exploratory clinical study to test a new treatment combination including cadonilimab and anlotinib in recurrent, metastasis and persistent cervical cancer. All participants will receive cadonilimab of 10mg/kg every three weeks at day 1, take anlotinib (8mg) orally in day 1 to day 14, then take a 7-days break and subcutaneously injection of GM-CSF (200ug) from day 1 to day 14, then also take a 7-days break. This treatment will continue until progression or intolerable toxicity or withdraw of participants and it will last for no longer than 2 years.

9. Sitting blood pressure in a resting state is below the normal high value (<140/90 mmHg), or 24-hour dynamic blood pressure monitoring average blood pressure is below the normal high value (<140/90 mmHg), regardless of whether antihypertensive drugs are being taken orally;
10. Hematological indicators meet the following criteria (not transfused or administered hematopoietic growth factor drugs within the past 7 days): white blood cell count (WBC) ≥3.5×109/L, absolute neutrophil count (ANC) ≥1.5×109/L, platelets (PLT) ≥100×109/L, hemoglobin (Hb) ≥90g/L;
11. Liver function indicators meet the following criteria: ALT and AST ≤2.5 times the upper limit of normal (ULN), bilirubin ≤1.5×ULN, albumin ≥35g/L;
12. Coagulation function indicators meet the following criteria (not receiving anticoagulant or hemostatic drug therapy): PT and APTT ≤1.5×ULN, while INR ≤1.5 ULN;
13. Renal function indicators meet the following criteria: blood urea nitrogen (BUN) and creatinine (Cr) ≤1.5×ULN, urinary protein <2+ or 24-hour urinary protein quantification <1g;
14. Women of childbearing age must undergo serum pregnancy testing within 7 days before initial medication, with negative results, and not be lactating. Female subjects of childbearing age must agree to use effective contraception during the study period and within 180 days after the last dose of the study drug;
