Trastuzumab Rezetecan in Advanced Solid Tumors Refractory to Standard Therapies

This study is a single-center, multi-cohort, phase II clinical trial. Eligible patients with HER2-positive advanced solid tumors were enrolled after providing informed consent. A total of 90 patients were allocated into three cohorts (30 patients each): those with Extramammary Paget's Disease (EMPD), rare solid tumors, or urothelial carcinoma, who had experienced failure of standard treatment or for whom no standard treatment was available. The participant recruitment period was 12 months, and the follow-up duration was 12 months. All patients received Trastuzumab Rezetecan (SHR-A1811) at a dose of 4.8 mg/kg administered every three weeks (q3w). They were followed until disease progression, withdrawal from the study, loss to follow-up, or death, whichever occurred first. Tumor response was assessed radiologically every 6 weeks during treatment. Safety follow-up was conducted 30 days after the last dose, followed by survival follow-up every 3 months thereafter.

Fluorouracil, Leucovorin, Gemcitabine, and Cisplatin in Treating Patients With Metastatic or Unresectable Adenocarcinoma of the Urothelium or Urachal Remnant

RATIONALE: Drugs used in chemotherapy, such as fluorouracil, leucovorin, gemcitabine, and cisplatin, work in different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving fluorouracil together with leucovorin, gemcitabine, and cisplatin works in treating patients with metastatic or unresectable adenocarcinoma of the urothelium or urachal remnant (part of the bladder).

Ivonescimab in the Treatment of Multiple Advanced Tumors

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

Agnostic Therapy in Rare Solid Tumors

The ANTARES study is a phase II basket trial designed to evaluate the tissue-agnostic efficacy of the monoclonal anti-PD1 antibody, nivolumab, in patients with advanced or metastatic rare tumors. The study aims to treat rare malignancies with PD-L1 expression (CPS ≥ 10), regardless of the tumor's tissue type or location. Patients who have not responded to standard treatments will be included, and treatment will last for up to 12 months. The study will assess objective response, progression-free survival, and biomarkers such as PD-L1, ctDNA, and microvesicles, in a multicenter collaborative effort to provide innovative therapeutic options for this underrepresented population

Multi-cohort, Single-arm Phase II Study of Albumin-paclitaxel, Ifosfamide, and Cisplatin in the Treatment of Rare Advanced Tumors

The goal of this clinical trial is to learn if albumin-paclitaxel, ifosfamide and cisplatin (Nab-TIP) works to treat advanced rare tumors including PAGET's disease of scrotum with infiltrating sweat gland carcinoma （cohort 1）, rhabdomyosarcoma (cohort 2), testicular cancer (cohort 3), penile cancer (cohort 4), and urachus cancer (cohort 5) . It will also learn about the safety of Nab-TIP. The main questions it aims to answer are: Does Nab-TIP improve the objective response rate and prolong the survival of participants? What medical problems do participants have when receiving the regimen of Nab-TIP? Participants will: Receive albumin-paclitaxel 260mg/m2 d1, isocyclophosphamide 1500mg/m2 d2-5, and cisplatin 25mg/m2 d2-5 every 21 days until disease progression, intolerable toxicity, or full 6 cycles of treatment, whichever occurs first. Be performed imaging evaluation according to RECIST 1.1 every 6 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
