About
This Phase Ib/II clinical study is an open-label, multi-cohort, two-stage trial designed to assess the safety and efficacy of different doses of TT-00420 tablets in combination with Toripalimab injection for treating patients with advanced urological tumors. The study aims to evaluate the effectiveness of TT-00420 tablets at the optimal dose combined with Toripalimab in treating different types of advanced urological tumors.

Inclusion criteria
Voluntary participation, sign the informed consent with good compliance.
Age between 18-80 years.
ECOG performance status of 0 or 1; expected survival of at least 3 months.
Meeting all criteria for one of the following cancer types:
Renal Clear Cell Carcinoma:
Urothelial Carcinoma:
Prostate Cancer:
Adequate major organ function, laboratory test criteria:
Hematology:
Biochemistry:
Coagulation:
Activated Partial Thromboplastin Time (APTT), International Normalized Ratio (INR), Prothrombin Time (PT) ≤ 1.5×ULN.
Fertile women must agree to contraception during the study and for 3 months after the last administration of the study drug.
[Failure Definition: Disease progression during treatment or after the last treatment, or intolerable toxicity due to side effects during treatment. Prior neoadjuvant or adjuvant treatment is allowed. If disease relapse or progression occurs within 6 months after the end of neoadjuvant/adjuvant treatment, it is considered a failure of first-line treatment for progressive disease.]
Exclusion criteria
Primary pure neuroendocrine cancer (except post-treatment neuroendocrine differentiation).
Other antitumor treatments within 4 weeks or 5 half-lives (whichever is shorter) before the start of the study treatment (except androgen deprivation therapy for prostate cancer patients, such as LHRH agonists or antagonists, bicalutamide, flutamide, etc.), or not yet recover from the toxicity of previous treatments (except ≤ G1 adverse events or tolerable G2 alopecia, fatigue/asthenia, and neuropathy caused by trauma at baseline).
Concurrent diseases/history:
Clinically significant hemoptysis (> 50 mL per day) within 3 months before enrollment; significant clinical bleeding symptoms or clear bleeding tendency, such as gastrointestinal bleeding, bleeding gastric ulcers, baseline fecal occult blood and above.
Arteriovenous thrombotic events within 6 months before enrollment, such as cerebrovascular accidents (including transient ischemic attacks), deep vein thrombosis (except venous thrombosis caused by previous chemotherapy with venous catheterization judged by the investigator as cured), and pulmonary embolism.
Hypertension not well controlled with stable dose antihypertensive treatment (systolic pressure > 150 mmHg or diastolic pressure > 100 mmHg); myocardial infarction, severe/unstable angina, NYHA class 2 or above heart failure, clinically significant supraventricular or ventricular arrhythmias, prolonged QT interval, and symptomatic congestive heart failure within 6 months before baseline/screening.
Interstitial lung disease, non-infectious pneumonia, and other non-specific pneumonias (e.g., pulmonary fibrosis, interstitial pneumonia).
Active infection requiring antibiotic treatment within 4 weeks before the first administration of the study drug, or unexplained fever > 38.5°C during screening or before the first administration of the study drug (fever due to tumor reasons judged by the investigator is allowed for enrollment); active tuberculosis.
Live attenuated vaccine vaccination history within 28 days before the first study drug administration or expected live attenuated vaccine vaccination during the study (including COVID-19 vaccine).
HIV infection or known acquired immunodeficiency syndrome (AIDS).
Active HBV infection (other abnormal HBV serology tests besides hepatitis B surface antibody positive or ≥ ULN, HBV DNA copy number required to confirm activity) and/or HCV infection (HCV RNA copy number required to confirm activity if hepatitis C virus antibody is abnormal).
Major surgery, extensive radiotherapy within 28 days before enrollment, or local palliative radiotherapy within 2 weeks.
Baseline: ≥ G2 peripheral neuropathy; active brain metastases, carcinomatous meningitis, spinal cord compression, or imaging studies (CT or MRI) at screening showing brain or leptomeningeal disease (patients with brain metastases who have completed treatment and stabilized symptoms within 14 days before enrollment are allowed, but must be evaluated by cranial MRI, CT, or venography to confirm no symptoms of cerebral hemorrhage).
Factors significantly affecting oral drug absorption, such as inability to swallow, history of total gastrectomy, short bowel syndrome, or clinically significant intestinal obstruction.
Participants who have received or are preparing to receive allogeneic bone marrow transplantation or organ transplantation.
History of severe allergy, immunostress, or other hypersensitivity reactions to chimeric or humanized antibodies or fusion proteins; hypersensitivity or allergy to any component of Toripalimab injection.
Active autoimmune diseases requiring systemic treatment within 2 years before the first administration of the study drug. Replacement therapy is not considered systemic treatment.
Diagnosed with immunodeficiency or receiving systemic corticosteroid treatment or any form of immunosuppressive therapy, and continuing to use within 2 weeks before the first administration of the study drug.
Pregnant, breastfeeding, or planning to become pregnant during the study. 5. Other serious physical or mental illnesses or laboratory test abnormalities that may increase the risk of participating in the study, interfere with study results, or patients deemed unsuitable for the study by the investigator.
