Safety, Pharmacokinetics, and Pharmacodynamics of the TLR4 Agonist GSK1795091 in Healthy Individuals: Results from a Randomized, Double-blind, Placebo-controlled, Ascending Dose Study.

Safety, Pharmacokinetics, and Pharmacodynamics of the TLR4 Agonist GSK1795091 in Healthy Individuals: Results from a Randomized, Double-blind, Placebo-controlled, Ascending Dose Study. Clin Ther. 2020 Jul 30;: Authors: Hug BA, Matheny CJ, Burns O, Struemper H, Wang X, Washburn ML Abstract PURPOSE: Interest in Toll-like receptor (TLR) agonists for cancer treatment has been renewed after promising preliminary clinical data in combination with checkpoint inhibitors. This first-in-human study assessed the safety, tolerability, and pharmacokinetic (PK) and pharmacodynamic (PD) properties of intravenous GSK1795091, a synthetic TLR4 agonist, in healthy volunteers as a precursor to evaluation in patients with cancer. METHODS: Healthy participants were randomized (1:3; double-blinded manner) to receive placebo or a single intravenous injection of GSK1795091 at doses of 7-100 ng. The primary objective was to evaluate the safety and tolerability of GSK1795091; secondary and exploratory objectives were to characterize GSK1795091 PK and PD properties. FINDINGS: Forty participants received study treatment (10 received placebo and 30 received GSK1795091). Overall, 3 of the 10 participants (30%) who received placebo and 16 of the 30 (53%) who received GSK1795091 experienced ≥1 adverse event (AE). The most common AEs were influenza-like illness, headache, back pain, and increased body temperature. One participant experienced late-o...
