The research will be conducted at Baylor College of Medicine (BCM) and Baylor St. Luke's Medical Center (BSLMC). All patients will receive standard of care treatment for their pancreatic cancer. Standard of care treatment will be gemcitabine in combination with nab-paclitaxel given on days 1, 8, and 15 of a 28 day cycle. Arm 1: LOAd703 treatment will be initiated at day 15 of the first cycle and given every other week for 6 doses. Depending on the location of the tumor the injection of LOAd703 can be given in different ways. The most common route of injection is ultrasound-guided percutaneous injection, but endoscopic ultrasound-guidance will be used for some patients as appropriate. All patients will receive anti-anxiety drugs or sedation as needed for comfort during the procedure. This study evaluates different doses of LOAd703. All patients will receive six injections of LOAd703. If patients in either phase of the study are judged by the investigator to be deriving clinical benefit from LOAd703 once all scheduled injections have been administered, they will be eligible to receive up to 6 additional biweekly doses of LOAd703. Arm 2: the same procedures as arm 1 in regard to LOAd703. In addition, the arm 2 patients will receive atezolizumab at a fixed dose, every chemotherapy cycle day 1. The treatments can continue until the final follow-up visit. Follow-up visits: Besides visits to receive treatments, patients will continue to visit BCM/BSLMC or their local doctor for evaluation of health status and side effects. At some visits blood samples will be obtained. Some of the blood samples being obtained are considered standard of care to ensure patient safety for standard of care treatment and the LOAd703 injection. However, some blood and biopsy samples (in applicable patients) will be collected to be analyzed for the presence of LOAd703, atezolizumab tumor markers and immunology markers. The extra blood will be 5-15 ml (3 teaspoonfuls) of blood collected at the screening visit and at eight different time points both during treatment and after treatments are completed. Imaging of the tumor to determine tumor size will be done every two to three months, which is routine for the monitoring of patients with pancreatic cancer. Patients will actively participate in the study for about 9 months when the final follow-up visit will be scheduled (or 12 months if additional doses of LOAD703 are given). After their active participation is completed patients will continue to receive routine care and will be contacted by the study team every 3 months to provide follow up on the status of their disease.
