Clinical Trial Summary

The goal of this clinical trial is to evaluate the efficacy and safety of toripalimab plus actinomycin-D as fist-line treatment in patients with gestational trophoblastic neoplasia with FIGO score 7. The main questions it aims to answer are:

• Whether toripalimab plus actinomycin-D as fist-line treatment can achieve a high complete response rate.

• Whether an equally high cure rate can be achieved by multi-drug chemotherapy as second-line treatment in patients who have failed fist-line treatment with toripalimab plus actinomycin-D.

Participants will receive toripalimab plus actinomycin-D. Treatment will be continued until disease progression, unacceptable toxicity, or withdrawal of consent. Treatment will be completed after 4 consolidation cycles.

Description:

The goal of this clinical trial is to evaluate the efficacy and safety of toripalimab plus actinomycin-D as fist-line treatment in patients with gestational trophoblastic neoplasia with FIGO score 7.

Eligible Participants will receive toripalimab (200mg q2w intravenous) plus actinomycin-D (1.25mg/m2，2mg max dose, intravenous). After normalization of serum β-human chorionic gonadotropin (β-hCG) levels, patients will receive 4 cycles of consolidation treatment. Treatment will be continued until completion of treatment, disease progression, unacceptable toxicity, or withdrawal of consent. The primary endpoint is complete remission rate (the proportion of patients achieving complete remission). Secondary endpoints include objective response rate (the proportion of patients achieving complete remission and partial remission), progression-free survival (time from the treatment initiation to disease progression or death, whichever comes first), disease control rate, duration of response, overall survival (time from the treatment initiation to the date of death or last follow-up), duration of response (time from the first evidence of response to disease progression or death, whichever comes first) safety, biomarker, ovarian function and quality of life.

5. Live vaccines injected within 30 days before the first dose of study drug;

6. Systemic immune stimulant agent (such as a bacterial or viral vaccine, colony-stimulating factors, interferon, interleukin, and combined vaccine) was used 6 weeks before administration or within the 5 half-lives of the drug, whichever is shorter.

7. Previous treatment with immunotherapy drugs (including antibodies targeting PD-1, PD-L1, PD-L2, cytotoxic T-lymphocyte-associated protein 4, T-cell receptor, chimeric antigen receptor T-cell therapy, and other immunotherapy).

8. Known hypersensitivity or allergy to actinomycin-D, toripalimab or any of their excipients.

9. Any active autoimmune disease requiring systemic treatment during the past 2 years.

10. History or current status of non-infectious pneumonia requiring steroid treatment.

11. Receiving steroid hormones (prednisone dose > 10mg/ day) or other immunosuppressants within 14 days before enrollment, excluding those on hormone replacement therapy.

16. Uncontrollable hypertension (systolic blood pressure =140 mmHg or diastolic blood pressure =90 mmHg, despite with the optimal drug therapy).

17. Abnormal coagulation (international normalized 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.

18. History of cerebrovascular accident (including transient ischemic attack, cerebral hemorrhage, cerebral infarction), deep vein thrombosis and pulmonary embolism within 3 months before enrolment.
