Therapeutic Solutions Receives Allowance on Patent Claim from the US Patent Office Covering ProJuvenol(R) Active Ingredient Pterostilbene in Cancer Immunotherapies
Company Developing Proprietary Nutraceutical ProJuvenol(R) to Augment FDA Approved Drugs that Help Immune System Fight Cancer
OCEANSIDE, CA --(Marketwired - February 06, 2017) - Therapeutics Solutions International, Inc., (OTC PINK: TSOI) announced today that the United States Patent and Trademark Office allowed issuance of a claim covering the combination of pterostilbene, the active ingredient in its ProJuvenol® product, together with an FDA-approved immunotherapeutic drug named Proleukin® (aldesleukin), which is a recombinant form of the cytokine interleukin-2 (IL-2) for treatment of cancer.
Proleukin® is one of the first immunotherapeutic drugs approved by the FDA, being indicated for treatment of metastatic melanoma and metastatic renal cell carcinoma1. Scientists working with Therapeutic Solutions International performed animal studies showing that administration of pterostilbene increased efficacy of Proleukin® in melanoma models. In the studies performed to obtain FDA approval for Proleukin® responses were seen in 16% of patients2. Based on animal data, it is hoped that the response rate of Proleukin® can be increased by administration of products containing pterostilbene, such as ProJuvenol®.
"It is important to understand that the immune system does not work in isolation. The findings by Therapeutic Solutions International that immune killing of cancer can be augmented by nutritional modification supports relatively easy to implement approaches that may have an impact on patient survival," said Santosh Kesari, MD, Ph.D., member of the Company's Scientific Advisory Board. Dr. Kesari is also the Chair of Translational Neurosciences and Neurotherapeutics at the John Wayne Cancer Institute and the Pacific Neuroscience Institute.
Immuno-Oncology, described by Science Magazine as 'Breakthrough of the Year3' offers the possibility of not only killing tumor cells in a non-toxic manner, but also establishing immunological memory, which patrols the body and destroys recurrent tumor cells. While great progress has been made in developing drugs that stimulate the immune system to recognize and kill tumors, a major pitfall of current approaches is that tumors produce chemicals and oxidative stress that suppresses the immune system, thus limiting efficacy of immune therapies. The unique properties of pterostilbene are believed to be useful in overcoming factors used by the cancer to protect itself from the immune system. Independent scientific studies have shown that pterostilbene, which is chemically related to resveratrol, has been published to possess anticancer4,5, antioxidant6, and anti-inflammatory activities7.
"We are confident that this validation of our science by the United States Patent and Trademark Office, combined with our ongoing basic and applied research efforts will help offer patients non-toxic means of augmenting existing drugs that work by modulating the immune system," said Timothy Dixon, President and CEO of Therapeutic Solutions International.
