Calidi Biotherapeutics Announces Two Abstracts Accepted for Presentation at the Society for Immunotherapy of Cancer's (SITC) 33rd Annual Meeting


SAN DIEGO,  /PRNewswire/ -- Calidi Biotherapeutics, Inc., a clinical‐stage biotherapeutics company at the forefront of cell-delivered oncolytic viruses for the treatment of cancer, today announced that data from its clinical studies in late-stage cancer patients will be presented at the Society for Immunotherapy of Cancer (SITC) upcoming 33rd  Annual Meeting, which is being held from November 7 to November 11, 2018, in Washington, D.C. at the Walter E. Washington Convention Center. Calidi will be presenting data based on two accepted abstracts at SITC. These two presentations will highlight how Calidi's platform will significantly potentiate oncolytic virotherapy by using either autologous or a more scalable, off-the-shelf, allogeneic mesenchymal stem cell-based delivery technology. Additionally, the presentations will detail the safety findings and post-treatment observations from Calidi's first clinical trial of oncolytic vaccinia virus combined with adipose stromal vascular fraction (SVF) cells in autologous settings.
