Idaho-based Therapeutic Solutions International, Inc. reported potent synergy between its tumor blood vessel targeting StemVacs-V iPSC immunotherapy and several classical tumor-specific therapeutic vaccines. 

In a series of experiments, tumor growth administration of dead tumor cells together with StemVacs-V resulted in potent immunological memory to the tumor cells, which could be transferred to immunologically naïve mice. 

Additionally, the experiments demonstrated killing tumor cells using conventional approaches such as chemotherapy, when performed together with StemVacs-V iPSC, led to the development of immunological memory towards specific cancer.

"By targeting the blood vessels that feed the cancer, StemVacs-V iPSC causes enhanced necrotic cell death, which stimulates systemic immunity against cancer throughout the whole body," said Dr. James Veltmeyer, Chief Medical Officer of the Company, in a press release issued on June 7, 2021.

"We are extremely enthusiastic by the current data showing that our blood vessel targeting approach can be used to synergize with both cancer immunotherapies and non-immune therapies of cancer such as chemotherapy and radiation therapy."

The company stated It is believed that by starving the cancer of its blood supply, StemVacs-V iPSC may convert cold tumors to immunotherapy sensitive "hot tumors."

"This new finding is extremely exciting because it opens the door to synergies with other immunotherapies such as CAR-T therapies, which although successful in liquid tumors, to date have not yielded promising results in solid and/or cold tumors," commented Timothy Dixon, President, and CEO of the Company. 

Therapeutic Solutions International is focused on immune modulation for the treatment of several specific diseases.
