Therapeutic Solutions International Reports its NanoStilbene™ Nutraceutical Product Enhances Efficacy of FDA Cleared Cancer Immunotherapy in Animal Model of Cancer
New Data Supports Development of Patented Formulation of Blueberry Extract Pterostilbene as an Adjuvant to Immuno-Oncology Treatments
OCEANSIDE, Calif., July 22, 2019 (GLOBE NEWSWIRE) -- via NetworkWire -- Therapeutics Solutions International, Inc. () reported today positive animal data demonstrating synergy between its commercially available NanoStilbene™ nutraceutical product [1] together with anti-CTLA4 antibody, which is the mouse equivalent of Ipilimumab (Yervoy®), an FDA cleared immunotherapeutic which belongs to the family of drugs called "checkpoint inhibitors". The new data supports the possibility that NanoStilbene™, a proprietary formulation of pterostilbene [2], may increase effectiveness of drugs that activate the immune system to kill cancer.
"The current set of animal experiments demonstrate not only that NanoStilbene™ enhances the ability of the CTLA-4 antibody to reduce tumor size, but also that NanoStilbene™ augments the number of lymphocytes entering the tumor. This data, together with previous publications that pterostilbene itself suppresses a wide variety of tumors, support the possible development of our nutraceutical as an adjuvant to numerous immunotherapies," said Thomas Ichim, Ph.D., Board Member of TSOI and coinventor on the Company's patents.
Numerous independent laboratories have published in the peer reviewed literature that pterostilbene decreases the growth of prostate cancer [3], breast cancer [4], glioma [5], liver cancer [6], esophageal cancer [7], and melanoma [8]. The advantage of NanoStilbene™ as compared to pterostilbene capsules, which are widely available, is that the proprietary nanoformulation allows substantially higher concentrations of pterostilbene to reach the cancer cells.
"We at Therapeutic Solutions International are focused on a Science First approach to development of all of our products. The new data disclosed today further supports our existing body of knowledge and patent filings which expand on our issued patent # 9,682,047, which covers utilization of pterostilbene with other immunotherapies," said Timothy Dixon, President and CEO of the Company. "We plan to expand our current studies in several areas, including exploring the effects of NanoStilbene™ on adoptive cellular immunotherapy and CAR-T cells."
