Cancer Clinical Trial
Official title:
A Single-Center Exploratory Clinical Study to Evaluate the Safety and Efficacy of RD133 in Subjects With Relapsed or Refractory MSLN-Positive Solid Tumors
This study is a single-center exploratory clinical trial. It is estimated that 9-24 subjects will be enrolled. The "3+3" dose escalation design is adopted. The main purpose is to evaluate the safety of RD133 in the treatment of subjects with relapsed or refractory MSLN-positive solid tumors and explore the Recommend phase II dose of RD133 in the treatment of patients with relapsed/refractory MSLN-positive solid tumors.

Subject with central metastasis or complete intestinal obstruction; 3. Subject with moderate or more severe hydrothorax and ascites which are hard to control by conventional treatment and require continuous catheter drainage; 4. With an active malignant tumor in the past 5 years, unless it is a curable tumor and has been obviously cured, such as basal or squamous cell carcinoma, cervical or breast carcinoma in situ, etc. 5. Subject with positive hepatitis B surface antigen (HBsAg) or hepatitis B core antibody (HBcAb) and abnormal HBV DNA test results in peripheral blood(abnormal HBV DNA test results are defined as: HBV DNA quantitative level higher than the lower limit of the detection center or higher than normal range of the detection center; or qualitative HBV DNA test positive);Hepatitis C virus (HCV) antibody positive and peripheral blood hepatitis C virus (HCV) RNA positive; Human immunodeficiency virus (HIV) antibody positive; Cytomegalovirus ( CMV) DNA test positive; syphilis test RPR positive. 6. With an uncontrollable active infection (except genitourinary system infection and upper respiratory tract infection <CTCAE Grade 2). 7. Severe heart disease: including but not limited to unstable angina, myocardial infarction (within 6 months before screening), congestive heart failure (New York Heart Association [NYHA] classification = grade 3), severe arrhythmia. 8. Subject with hypertension that cannot be controlled by medication. 9. The toxicity of previous treatment has not been relieved to baseline or =1(NCI-CTCAE v5.0, except for hair loss and laboratory abnormalities without clinical significance). 10. Major surgery within 2 weeks before enrollment, or has surgery planned during the time the subject is expected to be infused with RD133 or within12 weeks after RD133 infusion (except planned surgery under local anesthesia). 11. Subject who has a solid organ transplant. 12. Women who are pregnant or breastfeeding. 13. Subject with previous central nervous system diseases (such as cerebral aneurysm, epilepsy, stroke, Alzheimer's disease, mental illness, etc.) or mental disorders. 14. Other unstable systemic diseases judged by the investigator: including but not limited to severe liver, kidney, or metabolic diseases that require medication. 15. Known to have life-threatening allergic reactions, hypersensitivity reactions or intolerances to RD133 cell preparations or its components. 16. Subject with hemorrhage, severe thrombosis judged by the Investigator, or hereditary/acquired hemorrhage and severe thrombosis (including hemophilia, coagulopathy, thrombocytopenia, hypersplenism, etc.), or are receiving thrombolytic or anticoagulant. 17. The researcher believes that other situations are not suitable for inclusion in the group. |
