About Us Genelux is a Phase 3 biopharmaceutical company developing powerful therapeutics for patients suffering from difficult-to-treat cancers. Genelux is focused on the development of next-generation oncolytic viral immunotherapies that are designed to generate a personalized multi-prong attack to overwhelm a tumor's sophisticated defense mechanisms. Olvi-Vec (olvimulogene nanivacirepvec), is a proprietary, modified strain of the vaccinia virus (VACV), a stable DNA virus with a large engineering capacity having the potential to: Directly kill cancer cells Stimulate a tumor-specific immune response Ability to transform immunologically "cold" tumors into "hot" tumors allowing for responsiveness for immunotherapy Platform technology (ChoiceTM) is the foundation of our oncolytic immunotherapy product development program; and is designed to allow us to generate new product candidates rapidly from conception through the initiation of clinical trials.

Off-the-Shelf Personalized Medicine: Single Agent generates Individualized Results Long-lasting, Tumor-specific T cell response corresponds to tumor reduction Heavily pre-treated 9 prior regimens of chemo+Avastin; no pre-existing tumor-specific T-cells Post treatment Consequential amount (~3%) of all activatable T cells at Week 30 are tumor-specific T-cells Case Report (Pt #15A-05) No TSTcR 0 18 36 -24 Last Chemotherapy: Pemetrexed 3/30-5/18/2016 Progressive disease (PD) (CT scans on 6/30/2016 & 8/30/2016) GL-ONC1 Tx Partial response (confirmed on Week 24 & 36; durable) Stable disease @ Week 48 (-27% compared to baseline) Confirmed TSTcR Confirms tumor-antigen presentation & immune activation/memory (VIRO-15: monotherapy)
