NTS-105

Poster presentation at 39th Annual Symposium of the National Neurotrauma Society ATLANTA, June 27, 2022 /PRNewswire/ -- NeuroTrauma Sciences, LLC (NTS), a private biopharmaceutical company developing a portfolio of disease-modifying therapeutic candidates to treat the devastating effects of stroke and traumatic brain injury (TBI), today reported data on its novel neuroactive small molecule NTS-105 in a poster presentation at the 39th Annual Symposium of the National Neurotrauma Society in Atlanta, GA. Conducted by a research team led by Barclay Morrison, III, Ph.D., Professor of Biomedical Engineering at Columbia University, New York, NY, the study demonstrated the ability of NTS-105 to reduce cell death at a wide range of concentrations in preclinical models of TBI. NTS-105 is a novel, neuroactive steroid that crosses the blood-brain-barrier and reduces damage caused by inflammation and hypoxia. NeuroTrauma Sciences is developing NTS-105 for treating patients suffering from TBI and stroke. In this study, several concentrations of NTS-105 were compared to progesterone, which has demonstrated some promising results in TBI preclinical studies and clinical trials but did not provide statistically significant improvements in patients. As the authors discuss, progesterone can be difficult to dissolve in water, making it challenging to deliver clinically. A neuroprotective steroid with improved properties, such as NTS-105, may serve as a better option. In this study, 1nM progesterone and a wide range of NTS-105 concentrations between 0.1nM and 30nM were significantly neuroprotective. 300nM NTS-105 was not as neuroprotective as lower concentrations and like progesterone, NTS-105 may have a U-shaped dose response curve. The poster is available on the NTS website, . An abstract also will be published online in the Journal of Neurotrauma. "Our research clearly illustrates the ability of NTS-105 to decrease cell death in this in vitro model of TBI," said Dr. Morrison. "These early results support continued research and development of NTS-105 for traumatic brain injury." "The leading cause of death and disability in children and adults aged 1 to 44, traumatic brain injury, or TBI, is responsible for nearly 64,000 deaths annually," said D. Carl Long, Chief Executive Officer. "NeuroTrauma Sciences is dedicated to developing therapies for TBI, a field in medicine with one of the greatest unmet needs. We look forward to advancing NTS-105 into clinical trials." About NTS-104 / NTS-105 NTS-104 is a novel molecule that has demonstrated efficacy in preclinical models of acute TBI and ischemic stroke. NTS-104, a soluble prodrug, is readily delivered to the bloodstream where it is converted to the active neurosteroid NTS-105. NTS-105 rapidly enters the brain at concentrations sufficient to modulate key target receptors, protecting neurons from inflammation, ischemia and programmed cell death.

ATLANTA, June 7, 2022 /PRNewswire/ -- NeuroTrauma Sciences, LLC (NTS), a private biopharmaceutical company developing a portfolio of disease-modifying therapeutic candidates to treat the devastating effects of traumatic brain injury (TBI), today provided an update on the development of its lead drug candidates NTS-104 and NTS-105 in traumatic brain injury. Tom J. Parry, Ph.D., MBA, Chief Science Officer, presented recent results during an oral session at the 12th Annual Traumatic Brain Injury Conference held in Washington, DC. In this presentation, Dr. Parry discussed recent advances in the development of novel neurosteroids for the treatment of TBI, including preclinical data for its novel neuroactive small molecules NTS-104 and NTS-105, which NeuroTrauma Sciences is developing for acute, subacute and chronic brain injury treatment. The presentation is available on the NTS website, . Highlights of Dr. Parry's oral presentation: NTS-104 is a novel, water-soluble prodrug that converts rapidly to NTS-105 in plasma NTS-105 is a novel, potent neurosteroid that crosses the blood-brain barrier NTS-105 has nanomolar affinity for PR nuclear hormone receptors Administration of NTS-104 following TBI or stroke in rats improves functional outcomes and lesion volume NTS-104 administration reduces acute inflammatory mediators and inflamed cerebrovascular endothelial cell markers Efficacy has been demonstrated in multiple independent laboratories and models NTS-104 is expected to enter Phase 1 clinical trials in Q4 2022 NTS-104 has an issued composition-of-matter patent; NTS-104 and NTS-105 have issued method of use patents "Traumatic brain injuries elicit complex pathologies and represent a major cause of death and disability," said Dr. Parry. "Preclinical data for NTS-104 and NTS-105 demonstrate improved functional outcomes in TBI and offer promise for the treatment of these pathologies."
