Ivonescimab (PD-1/VEGF Bispecpecial Antibody) in the Treatment of Multiple Advanced Tumors: a Multi-cohort, Multi-center, Single-arm Phase II Study
The goal of this clinical trial is to learn if Ivonescimab works to treat advanced rare tumors including cohort 1: PAGET's disease of scrotum with infiltrating sweat gland carcinoma. cohort 2: Metastatic paraganglioma and pheochromocytoma. cohort 3: Metastatic renal angiomyolipoma and malignant perivascular epithelioid cell tumor. cohort 4: Rhabdomyosarcoma and Ewing's sarcoma cohort 5: Collecting duct carcinoma cohort 6: Urachal carcinoma. cohort 7: Neuroendocrine cancer. cohort 8: Basal cell carcinoma and sarcomatoid carcinoma. cohort 9: Penile cancer. cohort 10: Adrenal cortical cancer. cohort 11: Metastatic germ cell tumors, failure of standard cisplatin based therapy (mostly testicular cancer). cohort 12: Non-clear cell renal carcinoma (including renal papillary renal carcinoma); Renal cancer cannot be classified). cohort 13: Non-clear cell renal carcinoma (including chromophobe renal carcinoma) cohort 14: Other rare tumors that cannot be classified (such as testicular reticulum adenocarcinoma, etc.). cohort 15: Prostate cancer. cohort 16: Clear cell renal carcinoma. (16.1: received PD-1; 16.2: no PD-1 received) cohort 17: Urothelial carcinoma. cohort 18: Kidney cancer with brain metastases. cohort 19: Brain metastases of urothelial carcinoma. cohort 20: Rare tumors with brain metastases. It will also learn about the safety of Ivonescimab. The main questions it aims to answer are: Does Ivonescimab improve the objective response rate and prolong the survival of participants? What medical problems do participants have when taking Ivonescimab? Participants will: Receive Ivonescimab 20mg/kg intravenously every 21 days until disease progression, intolerable toxicity, or full 2 years of treatment, whichever occurs first. Be performed imaging evaluation according to RECIST 1.1 every 9 weeks for 1 year of treatment and every 12 weeks after 1 year Be recorded any adverse events in the whole study period including type, incidence, grade, severity, duration, and association with the study drug according to NCI-CTCAE V5.0 criteria
