 NEW YORK and LONDON, May 26, 2021 GLOBE NEWSWIRE -- Tiziana Life Sciences plc NASDAQ: TLSA, LSE: TILS Tiziana or the Company, a biotechnology company focused on innovative therapeutics for inflammatory diseases and cancers, today provided an update on further analysis of lymphocyte subsets from blood samples from a Phase 1 study with nasally administered Foralumab in healthy volunteers. Results exhibiting statistically significant immunomodulatory effects on CD8 cytotoxic T-lymphocytes and other inflammatory biomarkers were observed. This Phase 1 trial, conducted at the Brigham and Womens Hospital, Harvard Medical School, Boston, MA, was a single-site, double-blind, placebo-controlled, dose-ranging study with nasally administered Foralumab at 10, 50 and 250 mcg per day, consecutively for 5 days in healthy volunteers. The treatment was well-tolerated at all doses and there were no apparent symptoms of severe toxicity. Importantly, the treatment showed significant positive effects at 50 mcgday dose compared to other dose and placebo groups on T-cell subsets and inflammatory biomarkers. These data support other clinical and pre-clinical studies showing that this route of administration is capable of inducing site-targeted immunomodulation and anti-inflammatory effects. Furthermore these pharmacodynamic data point to a clinical dose range that Tiziana intends to test in further clinical development among MS patients.
