Forty patients with pancreatic cancer, sarcoma and carcinoma of breast will receive DNG64-CAR-V intravenously or intratumorally at a dose of 1-4 x 10e11 colony forming units (cfu) or equivalent 1.0-6.0 x 10e10 Vector Copies (VC) per dose one to three times a week. DNG64-CAR-V may be given alone or with one or more FDA approved cancer therapies/immunotherapies, or with certain FDA authorized investigational agents.
Based on previous Phase 1/2 US based clinical studies, DNG64-CAR-V does not suppress the bone marrow or cause organ dysfunction, and enhanced immune cell trafficking in tumors may cause the tumors to appear larger or new lesions to appear on CT, PET or MRI (pseudoprogression). Further, tumor stabilization/regression/remission have occurred later during the treatment period with DNG64-CAR-V monotherapy. Therefore, DNG64 -CAR-V will be continued if the patient has clinical benefit and does not have symptomatic disease progression.
Patient is ≥12 years of age, either male or female for patients with sarcoma; >18 years of age, either male or female.with pancreatic cancer or carcinoma of breast.
