New bladder cancer drug enters first human tests

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Any of the following clinical laboratory values During the screening period Hematology:absolute neutrophil count (ANC) \< 1.5 ×109/L, platelets \< 100 × 109/L, Hemoglobin\<90 g/L(Within 14 days prior to screening, no whole blood transfusion, component blood transfusion, or drugs such as colony stimulating factors \[For example: Granulocyte Colony-Stimulating Factor,Granulocyte-Macrophage Colony-Stimulating Factor,Erythropoietin,Thrombopoietin\] have been administered.) renal function:Creatinine\> 1.5×upper limit of normal(ULN)or Creatinine Clearance≥ 60mL/min(Calculate according to the Cockcroft-Gault formula); liver function(No history of liver protection treatment within 7 days prior to screening examination):Aspartate Aminotransferase \> 2.5 × ULN;Alanine Aminotransferase \> 2.5 × ULN;Total Bilirubin \> 1.5× ULN; ECG examination: QT interval corrected by Fridericia (QTcF) \> 450ms for males, QTcF \> 470ms for females; Coagulation function: Activated Partial Thromboplastin Time \> 1.5 × ULN; International Normalized Ratio \> 1.5 × ULN; Prothrombin Time \> 1.5 × ULN; 4\. History of or evidence of muscle-invasive, locally advanced, metastatic and/or extravesical bladder cancer (inclusive of the prostatic urethra). 5\. There are contraindications to cystoscopy and/or urethroscopy, such as urethral stricture, urinary tract infection (UTI) (referring to symptomatic infection with positive urine culture), gross hematuria, and small bladder capacity, etc; 6\. Bladder dysfunction during the screening period, such as severe urinary incontinence or overactive bladder (OAB); bladder perforation detected during the screening period through cystoscopy or imaging examination; 7\. During the screening period, if upper urinary tract tumors are detected during an upper urinary tract examination, or tumors in the prostatic urethra are detected during cystoscopy, or other malignant tumors are found within 5 years of the first dose, with the exception of skin basal cell carcinoma, squamous cell carcinoma, and cervical carcinoma in situ that have achieved complete remission or been effectively controlled through treatment, as well as Stage I/II cancers that have received adequate treatment, or stable prostate cancer that is under active monitoring in complete remission or well-managed through androgen therapy 8\. Symptomatic congestive heart failure, New York Heart Association (NYHA) class III or IV heart failure, or other severe cardiac dysfunction, which the investigator deems clinically significant. 9\. Severe/unstable angina pectoris, or myocardial infarction within 6 months prior to study entry. 10\. History or evidence of uncontrollable central nervous system disease. 11\. Past medical history or examination suggests active tuberculosis within 1 year prior to initial administration; 12\. Severely infected people who need to be controlled by antibiotics, antivirals or antifungals; 13\. Have a history of immunodeficiency, including HIV seropositivity, other acquired or congenital immunodeficiency diseases. 14\. The subject had received systemic glucocorticoid treatment within 2 weeks prior to the first administration of the test drug, except for the following situations: the hormone dose was ≤ 10mg/day in prednisone equivalent; local, inhaled, or intranasal use of glucocorticoids; and subjects with contrast medium allergy received prophylactic one-time use of glucocorticoids before undergoing imaging enhancement examination; 15\. History of active autoimmune disease; 16\. Active hepatitis B (HBe-Ag positive and HBV DNA\>=500 IU/mL), hepatitis C (HCV antibody positive and HCV RNA higher than the lower limit of assay detection) 17\. Received any other anti-tumor treatments within 4 weeks prior to the first dose, including systemic chemotherapy, small molecule targeted therapy, radiotherapy, and Chinese herbal medicine with anti-tumor effects, except for immediate bladder instillation chemotherapy performed after TURBT ≥ 14 days before dosing; Received immune checkpoint inhibitor therapy and antibody therapy within 6 months prior to the first dose; 18\. The study is undergoing treatment in other clinical trials or has ended until less than 4 weeks after the first administration of the study; 19\. The presence of other serious physical or mental illness, abnormal laboratory tests, and other factors that may increase the risk of participating in the study or interfere with the study results; And any other conditions that the investigator deems inappropriate for participation in this study.
