Oncolytics Biotech® Inc. will commence enrollment into a new GOBLET study pancreatic cancer cohort following both German regulatory and ethics approvals. This cohort will evaluate pelareorep in combination with modified FOLFIRINOX (mFOLFIRINOX) with or without the PD-L1 immune checkpoint inhibitor atezolizumab (Tecentriq®) in newly diagnosed patients with pancreatic ductal adenocarcinoma (PDAC). It is supported by a USD 5 million Therapeutic Accelerator Award from the Pancreatic Cancer Action Network (PanCAN), an innovative program established to accelerate the development of new treatments for pancreatic cancer.

The chemotherapy regimens of mFOLFIRINOX or gemcitabine + nab-paclitaxel are the two most common standards of care for pancreatic cancer. Oncolytics has already reported data with the combination of gemcitabine and nab-paclitaxel that surpassed historical outcomes. Positive results from a combination with mFOLFIRINOX could greatly enhance pelareorep's potential in addressing pancreatic cancer.

GOBLET Cohort 5: The mFOLFIRINOX cohort of the Phase 1/2 GOBLET study is designed to evaluate newly diagnosed PDAC patients treated with pelareorep + mFOLFIRINOX with or without atezolizumab. There will be a three-patient safety run-in to evaluate the tolerability of each treatment arm: pelareorep + mFOLFIRINOX + atezolizumab and pelareorep + mFOLFIRINOX. A total of fifteen evaluable patients will be randomized to each arm in Stage 1 of this Simon-two stage study.

The co-primary endpoints are objective response rate and safety. If Stage 1 success criteria are met, one or both treatment arms may be expanded to Stage 2 in which 17 additional evaluable patients per arm will be enrolled. Blood and tumor samples will also be collected for translational evaluations. GOBLET: The GOBLET (Gastrointestinal tumOrs exploring the treatment comBinations with the oncolytic reovirus peLarEorep and anT i-PD-L1) study is a phase 1/2 multiple indication study in advanced or metastatic gastrointestinal tumors.

The study is being conducted at 12 centers in Germany and is being managed by AIO-Studien-gGmbH. The co-primary endpoints of the study are objective response rate (ORR) and/or disease control rate assessed at week 16 and safety. Key secondary and exploratory endpoints include additional efficacy assessments and evaluation of potential biomarkers (T cell clonality and CEACAM6).

The study employs a Simon two-stage design with Stage 1 comprising five treatment groups: Pelareorep in combination with atezolizumab, gemcitabine, and nab-paclitaxel in 1st line advanced/metastatic pancreatic cancer patients; Pelareorep in combination with atezolizumab in 1st line MSI (microsatellite instability)-high metastatic colorectal cancer patients; Pelareorep in combination with atezolizumab and TAS-102 in 3rd line metastatic colorectal cancer patients; Pelareorep in combination with atezolizumab in 2nd line advanced and unresectable anal cancer patients; and Pelareorep in combination with mFOLFIRINOX with and without atezolizumab in newly diagnosed metastatic PDAC patients. Any cohort meeting pre-specified efficacy criteria in Stage 1 may be advanced to Stage 2 and enroll additional patients.
