DDFPe in Acute Ischemic Stroke, a Phase Ib/II Clinical Trial

Download Adobe Acrobat Reader DocumentThe results of a randomized, blinded, placebo-controlled clinical trial testing intravenous DDFPe in patiets with acute ischemic stroke are presented. 6 patients received placebo, six patients received 0.05 ml/kg of DDFPe every 90 minutes for three doses, six patients received 0.10 ml/kg of DDFPe every 90 minutes for three doses, and six patients received 0.17 ml/kg of DDFPe every 90 minutes for three doses. IV DDFPe appeared safe at all tested doses. No MTD was defined. Exploratory Aims suggest that early DDFPe treatment improves NIHSS quickly and high dose DDFPe patients suggested improved outcomes. Larger trials are warranted.

Dodecafluoropentane Emulsion (DDFPe) as a Resuscitation Fluid for Treatment of Hemorrhagic Shock and Traumatic Brain Injury: A Review

Download Adobe Acrobat Reader DocumentDodecafluoropentane emulsion (DDFPe) is a novel nanotechnology for oxygen delivery with therapeutic potential for hemorrhagic shock and/or traumatic brain injury (TBI). DDFPe demonstrates efficacy at smaller doses than previously tested perfluorocarbon oxygen therapeutics. This smaller dose potentially eliminates toxicities exhibited by previous oxygen therapeutics, while anti-inflammatory properties of DDFPe may alleviate damage from ischemia reperfusion injury. This mini-review summarizes our progress in developing a battle-field ready product to prevent combat death due to hemorrhagic shock and/or TBI.

Perfluorocarbon NVX-428 reduced secondary brain injury in a Swine Model of Traumatic Brain Injury

Adobe Acrobat Reader DocumentThis poster was presented at the National Neurotrauma Society Meeting, Snowbird, Utah, on July 11th, 2017. In this swine model of TBI, administration of DDFPe resulted in lower injury scores for spongiosis and ischemic neurons in the cerebellum as well as a decreased number of Fluoro-Jade B positive purkinje cells. This data suggests that DDFPe may play a role in mitigating secondary brain damage.

Dodecafluoropentane improves neurological function following anterior ischemic stroke.

Download Adobe Acrobat Reader DocumentDodecafluoropentane emulsion (DDFPe), an advanced oxygen transport drug, given IV at 90-min intervals maintains viability in the penumbra during cerebral ischemia in the standard rabbit anterior stroke model. This study investigated shortened dosage schedules of DDFPe in nonstandard posterior strokes following occlusions of the posterior cerebral arteries. In the standard anterior stroke group given DDFPe, the % stroke volume, neurological assessment scores, and serum glutamate were significantly decreased vs controls (p = 0.0016, 0.008, and 0.016, respectively). In the DDFPe nonstandard posterior stroke group, %SV, NAS, and serum glutamate did not differ statistically com-pared to nonstandard controls (p= 0.82, 0.097, and 0.06, respectively). In anterior strokes, DDFPe improves recovery but not in the more severe nostandard posterior strokes. Dated: 2016

Perfluorocarbon NVX-108 Increased Cerebral Oxygen Tension after Traumatic Brain Injury in rats.

Download Adobe Acrobat Reader DocumentHypoxia is a critical secondary injury mechanism in traumatic brain injury (TBI), and early intervention to alleviate post-TBI hypoxia may be beneficial. NVX-108, a dodecafluoropentane perfluorocarbon, was screened for its ability to increase brain tissue oxygen tension (PbtO2) when administered soon after TBI. NVX-108 caused an increase in PbtO2 following controlled cortical impact TBI in rats and should be evaluated further as a possible immediate treatment for TBI. Dated: 2016
