RD07 Cell Injection in the Treatment of Patients With Advanced Claudin18.2 Positive Solid Tumors

NCT05284968 | Unknown Early Phase 1 DMC

• 1 other identifier: BHCT-RD07-07
• Study Type: interventional
• Target: 36
• Locations: 0 countries
• Sites: N/A

Brief Summary

IP: RD07 cell injection; Target disease：solid tumor; Protocol design： Single arm, open label, dose increasing design. The experiment was divided into two stages: dose increasing stage and dose extension stage. After the completion of the dose escalation phase (9 or 12 cases) and the conclusion of safety, the investigator can select the appropriate dose group according to the safety, tolerance, and treatment response to enter the dose expansion phase. Dose extension stage (24 and 27 cases) according to the indications in the crowd into three queues: respectively for the integration of a stomach and the stomach esophagus adenocarcinoma, pancreatic cancer and other solid tumor, expand stage each queue number of cases can be determined by the actual filter and into the group of patients, no separate regulation, but two phase of the total case must not exceed 36 cases.

You may not qualify if:

• Received traditional Chinese medicine, Chinese patent medicine, etc. for the main purpose of anti-tumor treatment within 1 week.
• \) Those who used granule/granule-monoline colony-stimulating factor (G/GM-GSF) within 2 weeks before screening; 6) Patients who must use steroid hormones during CAR-T infusion (except for topical or inhaled steroid hormones); patients who are receiving systemic steroid therapy before screening and who are judged by the investigator to need long-term use of systemic steroid therapy during treatment. subjects (except inhalation or topical use); and subjects treated with systemic steroids within 72 hours before cell infusion (except inhalation or topical use); 7) Those with a history of serious heart disease, including but not limited to: history of acute myocardial infarction within 12 months, unstable angina pectoris, chronic heart failure of grade ≥III (standard of New York Heart Association), and electrocardiogram showing QT History of prolonged interval or severe arrhythmia; 8) Those with a history of craniocerebral trauma, disturbance of consciousness, epilepsy, cerebrovascular ischemia, cerebrovascular hemorrhagic disease, etc.; 9) Uncontrolled severe active infection (except for simple urinary tract infection and bacterial pharyngitis); 10) Subjects with positive hepatitis B surface antigen (HBsAg) or hepatitis B core antibody (HBcAb) and peripheral blood HBV DNA \>1000 copies/ml at screening; hepatitis C virus (HCV) antibody positive or peripheral blood HCV RNA positive ; Human immunodeficiency virus (HIV) antibody positive; Syphilis antibody positive; 11) Autoimmune disease subjects in need of treatment or subjects in need of immunosuppressive treatment; 12) The subject has a history of other primary cancers, except for the following: Non-melanoma cured by resection, such as skin basal cell carcinoma; Cervical carcinoma in situ, local prostate cancer, and ductal carcinoma in situ with a disease-free survival period of ≥2 years after adequate treatment; 13) The subject has a history of alcoholism, drug addiction or mental illness; 14) Inoculated with live or attenuated or inactivated vaccine within 4 weeks before screening; 15) Those who have a history of allergy to any component in the cell product; 16) Those who have participated in other clinical trials within 2 weeks before screening; 17) Pregnant, lactating women and subjects who are fertile and cannot take effective contraceptive measures (whether male or female); Any other condition that the investigator believes may increase the risk to the subject or interfere with the results of the trial.
