Toragen is focused on developing novel cancer treatments to treat viral-associated cancers and significant infections.
Toragen completed a Phase I clinical trial with its lead compound in HPV-induced cancer.
Toragen, Inc. is a clinical-stage oncology company focusing on the treatment of Human Papillomavirus (HPV) induced cancers, which cause 5% of all cancers worldwide.
Head and neck cancer (OPSCC) is a significant worldwide health issue with high mortality and morbidity. Despite an approved vaccine against HPV, incidences of HPV-induced cancers continue to rise and are expected to nearly double by 2040.
About 70,000 new cases of OPSCC are predicted to occur each year, resulting in 34,000 deaths.
Despite advances in therapy over the past decade, there remains significant morbidity and mortality from this disease. There is clearly an urgent need to develop effective new treatment options for patients with OPSCC.
Toragen identified a lead small molecule compound with a clear mechanism of action which is the inhibition of the HPV E5 oncogenic protein.
Toragen received an IND proceed letter in February 2023 and finished their Ph-I trial in 2H 2025. (Closed)
Toragen is now developing a second generation compound (TGN-S15) that has demonstrated increased efficacy and decreased side effects in preclinical testing.


Checkpoint Blockade Immunotherapy is revolutionizing oncology, with an estimated $30B market. Anti-PD-1/PD-L1 immunotherapy is now FDA approved to treat patients with recurrent or metastatic OPSCC with disease progression on or after platinum-containing chemotherapy. However, objective response rates to anti-PD-1 immunotherapy in HPV-induced cancers are typically below 25%. Thus there is a critical need to understand mechanisms of resistance and develop combination therapies to improve response rates.
