The purpose of this study was to determine the mechanism of action of SPI-0211 (Lubiprostone), a novel bicyclic fatty acid, under development for the treatment of bowel dysfunction. Adult rabbit intestine was shown to contain mRNA for ClC-2 by RT-PCR, Northern analysis, and in situ hybridization. T84 cells grown to confluence on permeable supports were(More)
The immunomodulatory properties of yeast β-1,3/1,6 glucans are mediated through their ability to be recognized by human innate immune cells. While several studies have investigated binding of opsonized and unopsonized particulate β-glucans to human immune cells mainly via complement receptor 3 (CR3) or Dectin-1, few have focused on understanding the binding(More)
BACKGROUND BTH1677 is a beta glucan pathogen associated molecular pattern (PAMP) currently being investigated as a novel cancer therapy. Here, the initial safety and pharmacokinetic (PK) results of BTH1677 in healthy subjects are reported. SUBJECTS AND METHODS In the Phase 1a single-dosing study, subjects were randomized (3:1 per cohort) to a single(More)
Imprime PGG (Imprime), an intravenously-administered, soluble β-glucan, has shown compelling efficacy in multiple phase 2 clinical trials with tumor targeting or anti-angiogenic antibodies. Mechanistically, Imprime acts as pathogen-associated molecular pattern (PAMP) directly activating innate immune effector cells, triggering a coordinated anti-cancer(More)
