About Targovax

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 targeted path-to-market indication
is mesothelioma, where the virus is currently being tested in a randomized phase
II trial. Another trial, in checkpoint inhibitor refractory advanced melanoma,
is expected to produce important proof-of-concept immune activation data in
heavily pre-treated patients.
