NEW YORK--(BUSINESS WIRE)--TONIX Pharmaceuticals (formerly known as Krele Pharmaceuticals), a specialty central nervous system (CNS) pharmaceutical company, announced today results of a new analysis of a Phase 2a study, which previously demonstrated reduced pain, fatigue and tenderness in patients with Fibromyalgia Syndrome (FMS) following bedtime administration of very low dosage (VLD) cyclobenzaprine (CBP). According to the analysis, VLD CBP treatment was associated with reductions in an objective measure of non-REM sleep instability, referred to as Cyclic Alternating Patterns (CAP) A2 & A3; these reductions were statistically significantly correlated with diminished pre-sleep/p.m. fatigue in FMS. The findings are the subject of a poster presentation at the American College of Rheumatology/Association of Rheumatology Health Professionals (ACR/ARHP) 2011 Annual Scientific Meeting.
