Therapeutic Solutions International Announces Clinical Proof of Concept of Nanoparticle Pterostilbene Formulation: NanoStilbene™
Early Clinical Trial Data Supports Enhanced Biodistribution of NanoStilbene™ Compared to Standard Pterostilbene When Orally Administered
OCEANSIDE, Calif., July 02, 2018 (GLOBE NEWSWIRE) -- Via OTC PR Wire -- Therapeutics Solutions International, Inc., (OTC Markets:TSOI) announced today pilot clinical data providing proof of concept that its NanoStilbene™ formulation of pterostilbene more effectively increases blood levels of the molecule as compared to conventional formulations. The clinical trial involves administration of NanoStilbene or comparator formulations of pterostilbene, to healthy volunteers, followed by a series of blood draws to determine the concentration of the compound.
"These early studies are critical to establishing the efficacy of our nanoparticle formulations to effectively deliver pterostilbene to the body," said Timothy Dixon, President, and CEO of Therapeutic Solutions International. "We are dedicated to developing First Class nutraceutical formulations that are science-driven. Through performing scientific validation at each step of the development process, we aim to fulfill this commitment to the Industry."
Pterostilbene is a naturally occurring analog of resveratrol, which has been published in the peer-reviewed literature to suppress the growth of various types of cancers1 including cervical cancer2, lung cancer3, triple negative breast cancer4, prostate cancer5, and glioma6.
"I am extremely pleased with the promising initial data we are receiving demonstrating efficacy of the NanoStilbene formulation to deliver enhanced concentrations of pterostilbene to the patient's blood stream," said Dr. James Veltmeyer, Chief Medical Officer of the Company. "Given the ability of pterostilbene to enhance the efficacy of chemotherapeutic drugs7, as well as having activity as a monotherapy in animal models, we are hoping to expand the use of this highly interesting molecule."
