ONCOS TG The survival rate for pancreatic cancer patients has not improved since the 1970s Improvement in 10 year survival rate % change over 40yrs. 1972 – 2012 No improvement in survival over the past 40 years www.targovax.com 13
ONCOS TG The RAS gene is mutated in >85% of pancreatic cancer patients, making it an interesting therapeutic target Incidence of RAS mutations One of the most common 100% mutations in cancer RAS is a well-defined neoantigen Results in cell division 50% permanently switched on No existing therapies targeting RAS Occurs in >85% of pancreatic cancer patients 0% 14 www.targovax.com
