BLESSED: Expanded Access for DNG64-CAR-V for Advanced Pancreatic Cancer, Sarcoma and Carcinoma of Breast

Brief summary public domain (ClinicalTrials.gov)

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.

Detailed description public domain (ClinicalTrials.gov)

DNG64-CAR-V is a replication incompetent chimeric tumor targeted amphtropic RNA vector that displays a Sig-binding decapeptide for binding to abnormally exposed Signature (Sig) proteins in the tumor microenvironment (TME) and encoding a CCNG1 inhibitor gene for killing cancer cells, neoangiogenic cells and pro-inflammatory, immune suppressive, stroma producing cancer associated fibroblasts (CAFs), thus reducing inflammation and converting an immune-cold to an immune-hot tumor, and reducing extracellular matrix production in the TME, hence augmenting drug entry and immune cell trafficking into the TME. Enhanced CCNG1 expression has been found in all cancer types tested at the Cancer Center of Southern California as of June 2023. Hence, in July 2023, the USFDA authorized the use of DNG64-CAR-V as platform therapy upon which one or more FDA approved cancer drugs immunotherapies and/or certain FDA authorized investigational agents may be added. This would allow a personalized approach in the treatment of all cancer patients. 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 VC per dose one-three times a week. DNG64-CAR-V may be given alone or with an FDA approved cancer therapy/immunotherapy and/or certain FDA authorized investigational agents on physician discretion.
