The genesis of ERC1671 occurred when Apostolos Stathopoulos was a neurosurgery student at the University of Liege. While observing an operation, a piece of a patient’s tumor hit his eye. At first, Stathopoulos panicked, but then he realized his body’s immune system would destroy the cancer cells.
2006
Stathopoulos conducts a proof-of-concept study on rats. The study finds that the combination of Syngeneic and allogeneic glioma cells injected into rats with growing tumors reduce the size and even eradicate them of the existing tumors and prevented the formation of new tumors. Stathopoulos patents the technique and founds ERC to develop the treatment for humans.
Gliovac obtains Orphan Drug status from the US FDA. Glioblastoma multiforme is the most common and deadly brain tumor in adults, but only affects 10,000-17,000 people in the US. By definition, an orphan disease affects under 200,000 people in the USA.
2012
First patients are treated with Gliovac/ERC1671 under a doctrine of compassionate use. In September, the first patient reached total remission.
Interim phase II trial results show that patients treated with Gliovac/ERC1671 and the commonly prescribed anti-cancer drugbevacizumab survived almost five months longer on average than those treated with bevacizumab alone.
2019
At the request of a patient, Gliovac/ERC1671 is the first medication prescribed under US Federal Right-to-Try laws passed by the Trump Administration. Despite being prescribed under Federal law, the treatment follows the protocols of California’s state Right-To-Try laws. ERC makes Gliovac available at free or reduced cost for Right-To-Try patients.
2020
ERC submits a European Medicines Agency marketing application authorization for ERC1671 under the brand name Sitoiganap. A second trial site opens at Harvard’s Dana Farber Center For Immuno-Oncology. ERC begins development of a Covid-19 vaccine called COVIDVAC based on Gliovac technology.

Sitoiganap /Gliovac/ERC1671 is an immunotherapy vaccine that trains the body’s immune system to attack a Glioblastoma using cells taken from the patient’s own tumor, along with tumor cells from three other donors. Unlike most vaccines, it is only given to patients who have already developed the disease, rather than prophylactically. By receiving tumor cells from different people, the patient’s immune system is exposed to several different tumor-associated antigens, or proteins, minimizing the chance that tumor cells might escape from the body’s defenses. It also is believed this approach will trigger a stronger cytotoxic T-lymphocyte response against the TAA on the patient’s tumor.In the first group of nine patients treated under the compassionate use doctrine, 100% survived for six months compared to only 33% in the control group. At ten months, 77% survived, compared to 10% in the control group. ERC1671 is currently in Phase II trials in the US, as well as being available under compassionate use protocols and right-to-try laws. According to the Innovation Observatory of the UK’s National Health Service:
The key principle underlying this particular vaccination approach is the use of a broad set of tumour antigens, derived from freshly resected whole tumour tissue – not only from the patient under treatment, but expanded to include the same from three independent GBM tissue donors. This multivalent array of autologous and allogeneic antigens is expected to reduce the chance of immune escape, which can emerge from antigenic loss or active major histocompatibility complex downregulation and is more likely to occur when using a single- or limited-antigen targeted immunotherapy. The future promise of this treatment might also rest in the ability to combine it with bevacizumab, and potentially with immune checkpoint inhibitors – an option that will allow more powerful immune activation in the periphery as well as more aggressive local tumour immunological targeting and destruction.
In April 2020, ERC began development on COVIDVAC, a vaccine for Covid-19 based on ERC1671’s underlying technology.
