Clinical Trial Summary
This study seeks to measure changes in cognition through verbal and visual test procedures
and changes in biomarkers of Traumatic Brain Injury and inflammatory and metabolic
parameters.
Description:
A growing body of literature recognizes neuroinflammation as a pivotal contributor to the
pathogenesis of TBI. A surge of inflammatory cytokines and chemokines, including tumor
necrosis factor-alpha (TNF-α), interleukin-1 (IL-1), interleukin-6 (IL-6), and nuclear factor
kappa-light-chain-enhancer of activated B cells (NF-kB), often follows TBI, leading to a
complex cascade of secondary events that ultimately result in neuronal damage and long-term
consequences.
It has been shown that patients with mild TBI have higher plasma inflammatory cytokine levels
than those without TBI at both 24 hours and 6 months following initial injury.The activation
of these inflammatory mediators has been demonstrated in both cerebrospinal fluid (CSF) and
serum of TBI patients. Elevated levels of TNF-α in CSF and serum have been associated with
injury severity and unfavorable outcomes in TBI.
IL-1, IL-6, and TNF-α induce the extracellular signal-regulated kinase (ERK) pathway,
promoting neuroinflammation. Furthermore, NF-kB, a crucial transcription factor in the
inflammatory response, plays a significant role in amplifying neuroinflammation post-TBI,
mediating the expression of several inflammatory cytokines and contributing to neuronal
apoptosis and cognitive impairment.
Neuroinflammation's contribution to sleep disturbances, fatigue, and cognitive impairment has
been increasingly recognized. These inflammatory cytokines may influence the
hypothalamic-pituitary-adrenal (HPA) axis and disrupt sleep architecture, leading to sleep
disturbances and fatigue. Further, they are known to induce synaptic alterations and neuronal
apoptosis, contributing to cognitive impairment.
Chronic, low-grade inflammation often ensues post-TBI, contributing to the persistent and
potentially insidious process leading to long-term impairment and diminished quality of life.
Apart from neuroinflammation, intracranial insulin resistance, another secondary consequence
of TBI, plays a significant role in the pathogenesis of TBI. Insulin resistance has been
observed in TBI patients, and it's linked to worse outcomes. In mouse models, induced TBI has
been shown to demonstrate reduced glucose uptake in mice brains on positron emission
tomography (PET) scans, consistent with the insulin resistance that has been seen in TBI
patients. Insulin resistance may exacerbate neuroinflammation, disrupt synaptic plasticity,
and contribute to cognitive deficits, further compounding the injury's impact.
If these symptoms remain untreated, they can significantly impair quality of life, limiting
independent living and reducing the ability to perform daily activities. They can also
predispose individuals to mental health disorders such as depression and anxiety and lead to
a higher risk of chronic diseases and premature death.
Currently, there is no therapeutic option to halt or fully reverse the sequelae from
traumatic brain injuries or the attendant neurophysiological deterioration. Other conditions
with similarly limited-to-no available and effective treatment strategies, including
Alzheimer's disease, share an overlapping deteriorative quality relating to neuroinflammation
and even reduced insulin functioning. A promising area of research among traumatic brain
injury and Alzheimer's treatment is investigating the use of insulin synthesizers; this study
group has also initiated a project involving NE3107 among patients with Alzheimer's disease
(IND 159271). In addition to IND 159271, several Phase 3 studies had been previously
initiated and/or completed with compounds such as Semaglutide, a hormone that stimulates
insulin signaling, Metformin, an insulin synthesizer , and NE3107, an anti-inflammatory
insulin-sensitizing agent.
In this study, the drug under investigation is NE3107 (17a-ethynyl0androst-5-ene-3b, 7b,
17b-triol). NE3107 is a small, blood-brain permeable molecule with anti-inflammatory and
insulin-sensitizing properties. The mechanism of action for NE3107 involves selective
inhibition of inflammatory mediators.
