Ampio Pharmaceuticals subsidiary Luoxis Diagnostics announces positive summary
data from study of traumatic brain injury patients and issuance of company's
third US patent for its oxidation-reduction potential diagnostic platform
GREENWOOD VILLAGE, Colo., Oct. 1, 2013
GREENWOOD VILLAGE, Colo., Oct. 1, 2013 /PRNewswire/ --Luoxis Diagnostics (a
subsidiary of Ampio Pharmaceuticals, Inc. (NYSE MKT: AMPE), today announced
results from a recently completed clinical study of patients with isolated
traumatic brain injury (iTBI). This study demonstrated statistically
significant correlations between oxidation-reduction potential (ORP) and the
severity of injury among iTBI patients. ORP is measured using the company's
proprietary RedoxSYS™ diagnostic system, a point-of-care diagnostic system
enabling rapid analysis of multiple markers of oxidative stress.
Increases in plasma static oxidation-reduction potential (spot measurement,
sORP) levels were consistently shown to closely correlate with increases in
iTBI severity as measured by the Abbreviated Injury Score (p=0.02). This
prospective observational cohort study of 645 iTBI patients was conducted at
two level-one trauma centers in the US over five years, and the analysis was
completed in September of 2013.
This is the second clinical study demonstrating the correlation between injury
severity in iTBI and oxidation-reduction potential [Rael LT, Bar-Or R, Mains
CW, Slone DS, Levy AS, Bar-Or D. Plasma oxidation-reduction potential and
protein oxidation in traumatic brain injury. J Neurotrauma 2009;26:1203-1211].
Importantly, this is the first study to show that negative changes in sORP and
cORP (a novel measure of patient antioxidant reserves) were associated with
poor patient outcomes, including discharge of patients to skilled nursing
facilities (SNF) and in-hospital mortality. This study demonstrates the
clinical utility of ORP measurements in the overall prognostic assessment of
iTBI patients to help predict numerous patient outcomes.
Of the 645 patients included in this study, 69% were <65 years old, 61% were
males, and median brain Abbreviated Injury Score (AIS) was 3. There were 11
deaths and 56 patients were discharged to a skilled nursing facility. After
adjustment in a multivariate logistic regression model, a 20mV increase in the
first ORP measurement (obtained within 48 hours of admission) was associated
with a 4-fold odds increase of in-hospital mortality (OR: 4.24, 95%CI:
1.2-15.3) and 1.3-fold odds increase of being discharged to a SNF (OR: 1.28,
95%CI: 1.00-1.63). Likewise, decrease in antioxidant reserves, as measured by
last inverse Capacity (1/cORP) were associated with significant patients
outcomes. For example a 1 unit increase in the last inverse cORP was
associated with a 5-fold odds increase in hospital mortality (OR: 5.05, 95%CI
1.2-21.3). Detailed results from this study will be presented at an upcoming
Luoxis' Chief Scientific Officer David Bar-Or, MD, commented "this recent
analysis in traumatic brain injury demonstrates again how oxidation-reduction
potential and antioxidant reserves serve as important markers of injury in
this significant condition. By having a novel measure like ORP available for
rapid analysis of oxidative stress and antioxidant reserves, we can enable
better clinical insights into these traumatic brain injury patients and
potentially improve clinical management based on their condition's severity
and ORP measures."
Traumatic brain injury affects at least 1.7 million patients in the US alone
each year, and the incidence is highest among patients 75 years of age and
older. Luoxis Diagnostics is studying specific conditions where oxidative
stress is implicated, and the company has a distinct focus on critical
illness, injury, and frailty among the elderly population. Additional studies
are ongoing to assess oxidation-reduction potential in multiple conditions,
and the RedoxSYS diagnostic system is in the final stage of development for
regulatory submissions in the US and elsewhere. As part of the company's
regulatory submission preparation, Luoxis has initiated ISO 13485:2003
certification to enable market access in the United States, European Union,
Canada, Australia, and elsewhere.
The company also announced the issuance of its third US patent (US patent
number 8,512,548) for the RedoxSYS diagnostic system. This patent covers a
broad range of clinical applications of the oxidation-reduction potential
platform to augment the company's previously issued patents for both the
RedoxSYS reader and disposable ORP sensors. The company expects the issuance
of many additional patents in the US, Europe, Canada, Japan, and other major
markets throughout the world.
Josh Disbrow, Luoxis' Chief Executive Officer explained, "the company has made
significant progress in its clinical and technical development as evidenced by
these recent clinical results and the issuance of this latest US patent. To
augment this progress, the company is also progressing toward regulatory
clearance in the US and elsewhere to enable broad commercialization of the
RedoxSYS system. We believe the oxidation-reduction potential platform will
fill an important, unmet need in the diagnosis of critical illness and
injuries like traumatic brain injury and look forward to announcing future
clinical trial results in the coming months."
About Luoxis Diagnostics
Luoxis Diagnostics, Inc. is an in-vitro diagnostics company focused on the
development and global commercialization of a point-of-care diagnostic device
and disposable sensors that measure the presence of oxidative stress and
antioxidant reserves in a patient. Oxidation-reduction potential is an
important measure in the detection of both critical and chronic illnesses and
is a novel marker of patient morbidity across a wide range of diseases and
conditions. There are numerous clinical indications for this homeostatic
parameter for which there is no currently available test. Luoxis is a
majority-owned subsidiary of Ampio Pharmaceuticals, Inc.
About Ampio Pharmaceuticals
Ampio Pharmaceuticals, Inc. is a development stage biopharmaceutical company
focused on the rapid development of therapies to treat prevalent inflammatory
conditions for which there are limited treatment options. We are developing
compounds that decrease inflammation by (i) inhibition of specific
pro-inflammatory compounds by affecting specific pathways at the protein
expression and at the transcription level (ii) activation of a specific
phosphatase or depletion of the available phosphate needed for the
inflammation process and (iii) decreasing vascular permeability – an upstream
event in the inflammation cascade.
About the RedoxSYS Diagnostic System
The RedoxSYS diagnostic system is a patented point-of-care diagnostic
instrument with accompanying disposable sensors that rapidly measures and
reports unique oxidative stress parameters by analyzing a single drop of a
blood or plasma. Prior to the development of the RedoxSYS diagnostic system,
oxidative stress measurement was incomplete, time consuming and impractical in
a clinical setting. The RedoxSYS diagnostic system has clinical application
across numerous critical and chronic illnesses. Multiple clinical trials have
been completed using the patented RedoxSYS diagnostic system that have
demonstrated the predictive value of the oxidative stress biomarkers uniquely
measured by the RedoxSYS system.
