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 70 participants in total. It began in 2022-01-27 with a primary completion date of 2026-12-01.

Brief Summary

The purpose of this study is to evaluate the efficacy and safety of camrelizumab and apatinib as combination therapy in patients with ultra high-risk (Cohort A) and high-risk chemo-refractory or relapsed (Cohort B) gestational trophoblastic neoplasia (GTN). Eligible patients will receive camrelizumab plus apatinib plus chemotherapy. Treatment will be continued until disease progression, unacceptable toxicity, or withdrawal of consent.

Eligibility Criteria

Inclusion Criteria: 1. Woman aged 18-60 years; 2. Previously untreated patients with ultra high-risk GTN（Cohort A） or high-risk chemo-refractory or relapsed GTN (Cohort B); 3. No previous chemotherapy or radiotherapy for ultra high-risk GTN（Cohort A）and have previously received two or more lines of combination chemotherapies for high-risk chemo-refractory or relapsed GTN (Cohort B); 4. Patients with ultra high-risk GTN (FIGO stages I-III: score ≥13 and stage IV) according to the International Federation of Gynecology and Obstetrics (FIGO) 2000 staging and risk factor scoring system（Cohort A）and patients with a prognostic score ≥7 (Cohort B); 5. Patients with an Eastern Cooperative Oncology Group (ECOG) performance status of 0-1; 6. Patients with abnormal serum hCG level (≥5 IU/L); 7. Expected survival ≥ 4 months; 8. The function of vital organs meets the following requirements: hemoglobin ≥90 g/L, absolute neutrophil count ≥1·5×109/L, platelets ≥100×109/L; creatinine ≤1·5 × upper limit of normal (ULN), urea nitrogen ≤2·5×ULN; total bilirubin ≤ULN, alanine aminotransferase and aspartate aminotransferase ≤2·5×ULN, albumin ≥25 g/L; thyroid stimulating hormone ≤ULN (if thyroid stimulating hormone is abnormal, normal T3 and T4 can also be acceptable). 9. Female patients of childbearing age must exclude pregnancy and are willing to use a medically approved high-efficiency contraceptive (e.g., intrauterine device, contraceptive or condom) during the study period and within 6 months of the last study drug administration. 10. The patient should be aware of the purpose of the study and the operations required by the study and volunteer to participate in the study before sign the informed consent form. Exclusion Criteria: 1. Previous treatment with immunotherapy drugs (including antibodies targeting PD-1, PD-L1, cytotoxic T-lymphocyte-associated protein 4, T-cell receptor, chimeric antigen receptor T-cell therapy, and other immunotherapy), anti-angiogenic small-molecule tyrosine kinase inhibitors (such as pazopanib, sorafenib, or regorafenib), or anti-angiogenic monoclonal antibodies (such as bevacizumab); live vaccines injected within 4 weeks before the first dose of study drug; other clinical trials of antitumour drugs within 4 weeks before the first dose of study drug; 2. Other malignancies in the past 3 years; 3. Immunosuppressive drugs used within 14 days prior to the first dose of camrelizumab; any active autoimmune disease or a history of autoimmune disease; 4. Uncontrollable hypertension (systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg, despite with the optimal drug therapy); 5. Grade II or higher myocardial ischemia, myocardial infarction or poorly controlled arrhythmia (females with QTc interval ≥470 ms); grade III to IV cardiac insufficiency according to New York Heart Association (NYHA) criteria, or cardiac color Doppler ultrasound evidence of left ventricular ejection fraction \<50%; myocardial infarction, NYHA grade II or above heart failure, uncontrolled angina, uncontrolled severe ventricular arrhythmia, clinically significant pericardial disease, or electrocardiogram suggesting acute ischemia or abnormal active conduction system occurring within 6 months before enrolment; 6. Abnormal coagulation (international normalised ratio \>1·5×ULN or prothrombin time \>ULN+4 seconds or activated partial thromboplastin time \>1·5×ULN), with bleeding tendency or undergoing thrombolysis or anticoagulant therapy; 7. Severe infections within 4 weeks prior to the first dose of study drug (e.g., need of intravenous infusion of antibiotics, antifungal or antiviral drugs), or unexplained fever (\>38·5°C) during screening or the first dose of study drug; 8. With a history of psychotropic drug abuse and are unable to withdraw the psychotropic drug, or have mental disorders; 9. Major surgery performed within 4 weeks before the first dose of study drug, or open wounds or fractures; 10. Obvious factors affecting oral drug absorption, such as inability to swallow, chronic diarrhea and intestinal obstruction, or sinus or perforation of empty organs within 6 months; 11. Routine urine test indicating urinary protein ++ or more, or confirmed urinary protein ≥1·0 g within 24 hours; 12. Human immunodeficiency virus infection or known acquired immunodeficiency syndrome, active hepatitis B (HBV DNA \>500 IU/mL), hepatitis C (hepatitis C antibody positive, and HCV-RNA higher than the lower limit of the analysis method) or co-infection with hepatitis B and hepatitis C; 13. Other reasons as judged by the investigator.
