How Theriva Biologics Is Using An Adenovirus To Develop A Novel Treatment For Pancreatic Cancer, As Well As Other Cancers With An Unmet Need

Pancreatic cancer has, unfortunately, been in the news lately due to the rising rates of early-onset cancer, especially in young people. The gastrointestinal cancer, which has a 12% five-year survival rate, is expected to become the second-highest cause of cancer-associated deaths in 2030 in the U.S. In 2024, it is projected that 64,440 Americans will be diagnosed with pancreatic cancer. 

The global market size for pancreatic cancer was valued at $2.22 billion in 2022, and it is expected to be worth around $7.91 billion by 2032. Despite the multi-billion dollar market size, the industry is expected to grow at 13.6% through 2032, and pancreatic cancer still needs more therapeutic options – especially for advanced cases or when existing treatments don't yield the desired results. Theriva Biologics TOVX is a biotech company that is looking to use adenoviruses to help treat pancreatic cancer. 

Adenoviruses are a class of viruses with an established safety profile. They are highly prevalent in the environment, making them ideal candidates for therapeutic use in the cancer field. Theriva Biologics’ lead product candidate, VCN-01, is a uniquely modified human adenovirus designed for systemic delivery to treat different types of cancer. 

Theriva Biologics reports that phase 1 clinical trials of VCN-01 have shown promising results for the treatment of several additional indications apart from pancreatic cancer, such as retinoblastoma, head and neck squamous cell carcinoma (HNSCC) and colorectal cancer (CRC) in combination with chemotherapy and immunotherapies. 

Currently, the company is conducting a phase 2b clinical trial of VCN-01 in combination with standard-of-care chemotherapy for first-line metastatic pancreatic cancer. It is on track to complete enrollment into the VIRAGE Study by the first half of 2024. In the first quarter of 2024, a Drug Monitoring Committee (DMC) conducted a thorough safety review of VCN-01, and found that the VCN-01 safety profile permitted the VIRAGE study to continue without modification. By the second half of 2024, Theriva Biologics aims to perform an interim analysis of the data obtained from the VIRAGE Study.

Pancreatic cancer presents several unique challenges that contribute to its high mortality rate and the difficulty in managing the disease. One major challenge is the aggressive nature of pancreatic cancer, which often spreads to other organs before being diagnosed. Approximately 50% of patients are diagnosed when the cancer has already metastasized, resulting in advanced-stage disease. Pancreatic cancer is also known for causing nonspecific symptoms, making it challenging to detect in its early stages.

VCN-01 has a systemic delivery approach, which means it can target both the main tumor and distant metastases, which makes it a promising therapeutic option for advanced and difficult-to-treat cancers like pancreatic cancer. If the company can successfully harness the benefits of adenoviruses, it will present suffering patients around the globe with a novel solution to extend their lives.
