  3. Slide 3: Mission

    MISSION We will leverage our proprietary product candidate, pelareorep (pela), an investigational first-in-class double-stranded RNA immunotherapeutic agent, to establish a platform immunotherapy for the treatment of gastrointestinal (GI) tumors. We believe GI tumors are the largest unmet medical ne

  4. Slide 4: Pelareorep Mechanism of Action

    PELAREOREP MECHANISM OF ACTION Pela infection kills some tumor cells by cell lysis and Intravenous pela evades neutralization by Pela selectively infects and replicates in tumor cells The pela-initiated inflammatory response results in initiates an inflammatory response, through associating with mon

  5. Slide 5: Pelareorep Has Been Observed to Replicate in Almost All Evaluated Tumors

    PELAREOREP HAS BEEN OBSERVED TO REPLICATE IN ALMOST ALL EVALUATED TUMORS Pela RNA is found in tumor but not stromal cells Pela is found in almost all on-treatment tumor biopsies Indication treated with IV Pela # of biopsied tumors # Pela-positive biopsies Pancreatic ductal 12 12 adenocarcinoma Metas
