Activating the Patient's Immune System to Fight Cancer

Targovax (OSE:TRVX) is a clinical stage biotechnology company developing immune activators to target hard to treat solid tumors. Immuno-oncology is currently one of the fastest growing therapeutic fields in medicine. Targovax’s lead product candidate, ONCOS-102, is a genetically modified oncolytic adenovirus, which has been engineered to selectively infect and replicate in cancer cells. It has been shown to activate the immune system to generate tumor-specific immune responses. In phase I trials, ONCOS-102 induced both local and systemic innate and adaptive immune activation, which has been associated with clinical benefit. ONCOS-102’s lead indication is mesothelioma, where the virus is currently being tested in a randomized phase II trial, with a phase Ib safety lead-in cohort. Another trial, in advanced melanoma, is expected to produce important proof of concept data for checkpoint inhibitor refractory patients within the next 6-12 months.

Targeting RAS mutations

Targovax is also developing a neoantigen cancer vaccine targeting tumors that express mutated forms of RAS – mutations known to drive cancer. The TG vaccine program has shown a signal of efficacy in a 32- patient trial with TG01 in resected pancreatic cancer. A next generation product candidate, TG02 is currently tested as monotherapy and will also be tested in combination with Keytruda® (an anti-PD1 Check point inhibitor, CPI).
