Study of Chidamide Combined With Immunotherapy in Patients With Locally Advanced or Metastatic Urothelial Carcinoma Who Had Previously Received Platinum-based Chemotherapy


Chidamide has been approved for the treatment of relapsed or refractory peripheral T-cell lymphoma in China (Chidamide,a novel histone deacetylase inhibitor). Tirelizumab,has been approved for the failure treatment of platinum-containing chemotherapy with high PD-L1 expression included locally advanced or metastatic Urothelial carcinoma in China(Tirelizumab,BGB-A317 is an investigational humanized IgG4 anti-PD-1 monoclonal antibody ).The aim of this study was to observe the efficacy and safety of Chidamide with Immunotherapy in patients with progression of platinum-based chemotherapy recurrent and metastatic Urothelial carcinoma.

Inclusion Criteria

Age 18 years, < 75 years
Histopathological diagnosis of transitional cell carcinoma or urothelial carcinoma; It may be associated with other cell types such as small cell carcinoma, neuroendocrine carcinoma or squamous cell carcinoma, but the component should be mainly urothelial carcinoma
Patients with advanced urothelial carcinoma (inoperable or metastatic to lymph nodes or distant metastases) recurred or progressed during adjuvant therapy or advanced first-line platinum-based chemotherapy; Patients receiving secondary chemotherapy may be included, but more than 12 months from the end of the first chemotherapy to the beginning of the second chemotherapy; Subjects who receive neoadjuvant chemotherapy or adjuvant chemotherapy and who develop disease progression within 12 months of the last dose are considered to be receiving systemic chemotherapy in the context of cancer metastasis (disease progression is defined as any progression requiring a change in treatment regimen prior to treatment)
Measurable target lesion (without radiotherapy) : defined as having at least one lesion that can be accurately measured in at least one dimension (the longest diameter recorded), such as 15mm conventional technique or 10mm helical CT scan; Patients with bone metastases may also participate in the study, provided they also have a measurable non-osseous disease

\. Acute toxicity caused by previous treatment is alleviated to level 1 (except hair loss)
The eligibility of patients receiving any drug or substance known or likely to affect cedaramide activity or pharmacokinetics will be determined after review by the principal investigator for a period of more than 6 weeks

Combined with other active malignancies (i.e., changes in treatment required within the past 24 months). Only patients with skin cancer that has been treated within the past 24 months and has been completely cured are allowed to be enrolled.
