                                         and to meet timetables associated with the applicable Statement of Work. The Parties
                                         shall use their respective reasonable efforts to perform the Project in accordance witl1
                                         federal, state and local laws and regulations applicable to the research, as appropriate,
                                         including, without limitation, academic standards and all laws and regulations
that apply to such standards and applicable ethical standards as well as in accordance with U.S. Food and Drug Administration
Good Laboratory Practice regulatory standards. For the avoidance of doubt, any clinical portions of the Project will be perforu1ed
in compliance with Good Clinical Practice as set forth in Title 21 of the U.S. Code of Federal Regulations (“C.F.R.”)
and all applicable local, state and federal Laws governing the perforu1ance of clinical investigations including but not limited
to the Federal Food, Drug, and Cosmetic Act as applicable. Neither Party guarantees that any patent rights shall result from the
Project, that the scope of any patent rights that may result shall cover either Party’s commercial interest or that any
such patent rights shall be free of dominance by other patents, including patents based upon inventions made by other inventors
employed by either Party independently of their collaboration in this Project. Neither Party provides any warranty as to the commercial
or scientific value of any results achieved under this Agreement. Scythian does not warrant the successful grant of its patent
application upon which this research Project is based, any non-infringement with regard to any third-parties’ rights, or
the success of the proposed drug regimen to be tested in the Project.

PRE
CLINICAL STUDIES

Year
I: 1/1/2017

Year
2: 1/1/2018

 

Background

 

Traumatic
brain injury (TBI) has been called the signature injury of modem warfare. A Rand Corporation survey published in 2008 estimated
that as many as 19.5% of those who deployed to Iraq or Afghanistan sustained TBI. (I) The Defense Centers of Excellence for Psychological
Health and Traumatic Brain Injury (DCOE) estimates that 1.7 Million People a year suffer a TBI and reports that almost 25,000
military members last year were diagnosed with a new TB!. (2) Traumatic brain injury can be caused by a variety of insults. In
the operations in Southwest Asia the vast majority of mild TBI (mTBI) has been caused by blast exposure. While combat is slowing
down in that region, blast exposure or concussive events will remain a threat to our troops worldwide as improvised explosive
type devices will continue to be a common mode of warfare wherever our troops are deployed. In fact recent incidents at home (Boston
Marathon Bombing and West Texas explosion) prove that those “In Conus” are also vulnerable to blast exposure. While
the sequelae of serious brain injury have been study for many years and well characte1izcd we are only beginning to get a picture
of the sequelae of blast-induced or concussive mTBI. Current literature suggests that the majority of symptoms are neurosensory
in nature. (3,4) Dizziness, hearing loss, headaches, and neurocognitive dysfunction are frequent sequelae and, while these resolve
over time in a certain portion of the population, they persist and can worsen in many individuals. (3) Moreover, there is an emerging
body of literature to suggest that over time mTBI secondary to blast can exhibit characteristics that suggest the presence of
neurodegenerative disorders in these patients. (5) As such, examining agents that can prevent or treat the neurosensory deficits
associated with blast or concussion induced mTBI remains an important objective that must be pursued. (6-8)

 

Rationale
for combination product chosen Cannabinoid modulation of neuronal NMDA receptor mechanisms was demonstrated conclusively
nearly two decades ago. (9) Given the evidence for anti-inflammatory efficacy of cannabinoids in processes that include
neuroinflammation, a strategy targeting jointly NMDA receptors and cam1abinoid receptors has therapeutic promise for the
treatment of consequences of mTBI. (10)

 

The
use of an NMDA antagonist as the first component of our drug combination focuses on controlling inflammation following a traumatic
head injury. We propose to use dexanabinol (also !mown as HU 211) as the selected NMDA antagonist. Dexanabinol has already been
tested in Phase II and Phase III clinical trials. (11) In prior studies of dexanabinol for use in the treatment of concussion,
one study showed that it lowered intracranial pressure. However, other studies appeared inconclusive at best and found that it
did not inhibit gliosis and the subsequent immune cascade. The studies failed to provide adequate support for the use of dexanabinol
as a single agent for the treatment of concussion. Notwithstanding, we believe that the use of dexanabinol, in synergistic combination
with a CB-2 agonist, will show benefit.

 

    	 

    	 	 	 

    

 

The
second component of the proposed drug combination is designed to increase levels of the endocannabinoid N-arachadonylcthanolamine
(anandamide) with a resulting decrease in the other major endocannabinod 2-arachadonoylglycerol (2-AG), among other actions. This
chemical effect is hypothesized to reduce inflammation and to inhibit gliosis via inhibition of the immune cascade. One way to
obtain this effect is through the use of a CB2 agonist. As such we propose to use cannabidiol (CBD), a naturally occurring chemical
in certain varieties of marijuana, as the second component for the study. CBD has no psychoactive effect. CBD acts as a CB-2 agonist
and presents a broad range of anti-inflammatory and immune inhibitory effects. There is extensive research into the cannabinoid
CB2 receptor as a target for inflammation-dependent neurodegeneration. (12) There is a long history of the study of CBD as an
anti-inflammatory agent and it has been tested in phase III clinical trials as a treatment for various disorders. This research
on the use of CBD and other cannabinoids as a possible treatment for various inflammatory disorders has been ongoing for no less
than 25 years.

 

However,
over the last 15 years, this research has picked up extensively. Aside from the general articles on cannabinoids and inflammation,
there are many articles that specifically address cannabinoids as a possible treatment for concussions. (13-16)

 

Given
the effects of the two compounds in terms of both anti-inflammatory and neuroprotective properties and the reported pathophysiology
of mild traumatic brain injury, a combined product appears to be a strategy worth considering. This protocol examines the use
of this combined product.

 

SCOPE
OF WORK:

 

Specific
Aims

 

1.       Determine
if SP (combined HU-211 and CBD product) administered post-blast or concussion and for seven days thereafter can reduce the neurosensory
sequelae of blast induced or concussive mTBI in a small rodent model when compared to placebo when the medicine is administered
after the blast or concussion.

 

2.
      Detem1ine if SP administered post-blast or concussion and for seven days thereafter can
reduce damage to brain and the hearing and balance sensory organs of blast induced mTBI in a small rodent model when compared
to placebo when the medicine is administered after the blast or concussion.

 

3.
      Determine if histological differences can be identified in SP treated vs. non-SP treated animals.

 

4.
      Determine if lipodomic characteristics are different in SP vs. non-SP animals

 

Materials
and methods

Experiment
summary 

 

This
experimental work will take advantage of previous work done with SP. As such there will be 8 initial treatment groups of 15 rats
per group/TB! model. The three TBI models are blast exposure (BLAST), a weight-drop closed head injury model (CHI), and a fluid
pressure injury (FPI model), which are described in more detail below. The groups are: Group A (SP alone), Group B (Vehicle alone),
Group C (Blast+ SP), Group D (BLAST +Vehicle), Group E (CHI +SP), Group F (CHI +vehicle), Group G (FPI +SP), and Group H (FPI+vehicle).
There will be 15 rats per group to allow us to look at short and longer-tem1 outcomes. All groups will undergo behavioral testing
(for sensorimotor, cognitive, and working memory function), hearing testing, and balance testing (as detailed below) pre-exposure
and at 3 and 7 days post-Exposure on all 15 animals in each group. One third of each group of animals will be sacrificed at seven
days (5 per group) and will undergo a gross examination and series of histochemical tests (documented blow). The second group
of five animals per group will undergo behavioral and hearing testing at day 14, 21, and 31 days before being sacrificed at day
31 at which point they will undergo the same terminal analysis as the seven day animals. The final five animals will be the long
tern1 group and will undergo behavioral and hearing tests at day 3, day?, day 31, day 61, and day 91 at which point they will
be sacrificed for the same histological analysis as the first two time point groups.

 

    	 

    	 	 	 

    

 

Budget
justification for Basic Science Medicines

 

Both
compounds HU211 (HU) and Cannabadiol (CB) will be purchased from Tocris Pharmaceuticals. HU costs $375/10 mg and CB costs $629/50
mg. The first years basic experiment calls for 80 animals that will receive 7 doses each for a total of 560 doses of both medicines
at the effective dose of 10 mg/kg CB and 1 mg/Kg HU. For a 500 mg rats the total expenditure for drug in year one is approximately
$50,000.

 

For
year two of the basic science work there will be two refinements undertaken. The first will be to use a higher dose of medicine.
This study will utilize only 30 rats each receiving seven doses of medicine at the effective dose of CB (20 mg/kg) and HU 2 mg/kg.
For 500 mg rats the total expenditure for drug will be $35,000. A second refinement will use the most effective of the first two
doses of medicine for 3 doses. For a 40 rate trial using either dose at only 3 total dosings will cost approximately $15,000 for
a total second year drug expenditure of $50,000.

 

Exposure
types

Blast
exposure

 

Rodent
Blast Wave Tube Exposures: The shock wave generator system is composed of a three foot compression tube that makes a pressure-sealed
fit by aligning with a single, 12 foot long by 8 inch inner diameter condensing tube. The compression tube is charged by an industrial
compressor. A hydraulic actuating device presses a sliding portion of the condensing tube against the compression tube over a
plastic film to seal off the compression tube. The system is operated remotely for management of the compression chamber to a
selected pressure, moving new film in position, closure of the condensing tube to the compression tube to make an air-tight seal
over the non-burst film, activation of an internal armature to burst the film at selected pressures, and moving new non-burst
film into place for the next blast event. The output of the tube renders a supersonic, Friedlander type overpressure/under-pressure
wave which simulates the shock pressure wave from explosive detonations. Overpressure intensities can be generated from 2 pounds
per square inch (psi) or 14.5 kilopascals (kPa) to >50 psi (.35 megapascals). Exposures for the single blast overpressure (BOP)
studies will range between 10 and 20 psi (depending on the initial reactions as determined on refinement animals). All animals
will be anesthetized and placed in an animal holding tube inserted and secured one-foot within the end of the condensing tube.
The animal holding tube positions the animal with the rat’s dorsal head surface to the on coming shock wave. Subjects will
be positioned 10 feet from the tube film diaphragm and will receive a BOP wave in a head-on orientation. The holding tube allows
for Isoflurane gas to feed to the animal to induce anesthesia allowing exposures to live but anesthetized animals. BOP waves will
be measured and displayed for peak intensities, rise time and BOP wave durations using a Pacific Instruments 6000 DAQ with up
to 32 channels, each with 250 kHz recording speed along with Dytran pressure transducers rated for O 50 PSI measurement range
and electronic conditioners interfaced with computers. An exposure will consist of anesthetized animals receiving a single blast
wave exposure. Our initial investigations will examine the effects of single 10-20 psi (Friedlander wave with overpressure-underpressure
sequence) which have been shown to demonstrate pathological effects (see Balaban et al J Neurosci Methods 2016).

 

    	 

    	 	 	 

    

 

Closed
Head Injury

 

Briefly,
male Sprague-Dawley rats are anesthetized with 3% isoflurane, 70% N2O and 30% 02 in a bell jar until no response to paw or tail
pinch. After initial anesthesia, animals are then maintained via nose cone with a maintenance dosage of 1-2.5% . Sterile eye lubricant
will be used so eyes do not dry out during surgery. Rats will undergo mild TBI (mTBI) by methods previously desc1ibed (Marmarou,
1994; Foda and Marmarou, 1994). Briefly, male Sprague Dawley rats are anesthetized with 3% isoflurane, 70% N2O and 30% 02 in a
bell jar until no response to paw or tail pinch. After initial anesthesia, animals are then maintained via nose cone with a maintenance
dosage of 1-2.5%. The animals head is shaved and wiped down with chlorohexadine. An incision is made to expose the skull. A steel
disc (10mm in diameter and 3mm thickness) is attached to the skull between bregma and lambda suture lines using dental acrylic.
Animals are then moved onto a foam mattress (Type E polyurethane foam) underneath the trauma device. A weight of 450 grams is
allowed to fall freely through a vertical tube from 1 meter. Body temperature is monitored using a rectal temperature probe and
temporalis muscle temperature is monitored as an indirect measurement of brain temperature. Sham animals will undergo all surgical
procedures but are not subjected to the brain trauma. After injury, animals are sutured closed and returned to their home cage
and given food and water ad libitum. If the animal has difficulty eating after injury then the animal will be eutl1anized. Animals
will have a tail artery catheter placed prior to brain injury and after brain trauma, animals will be intubated and administered
rocuronium or pancuronium as the paralytic.

 

Fluid
Percussion Injury

 

Sprague-Dawley
rats are anesthetized with 3% isoflurane for induction of anesthesia in a custom built anesthesia chamber. Toe pinch is perforn1ed
to make sure animals are appropriately anesthetized. Animals respiratory rate is visually assessed. Isoflurane anesthesia is then
maintained via nose cone and the injury cap is placed on the exposed dura as follows. The rat’s head is shaved and swabbed
with clorohexadine solution. The rat is then placed in a stereotaxic frame and the scalp surgically incised. A parasagittal craniotomy
(4.8 mm) using a trephine is performed at 3.8 mm poste1ior to bregma and 2.5 111111 lateral to the midline. A sterile plastic
injury tube (the plastic connector of a sterile needle cut 1 cm in length and trimmed to fill the craniotomy perfectly) is next
placed over the exposed dura and bonded by crynoacrylic adhesive to the skull. Dental acrylic is then poured around the injury
tube to obtain a perfect seal. After the acrylic has hardened, the injury tube is plugged with sterile gel foam sponge or with
a Luer Lok adapter, the scalp is stapled/sutured back. Animals are removed from the anesthesia and returned to their home cage.
Twenty-four hours after the previous preparation the rats are anesthetized with 3% isoflurane via a custom built anesthesia chamber
and toe pinch is used to determine anesthesia level, animal is placed on the table and anesthesia is administered via a nose cone
until cathethers are placed and the animals is intubated. A catheter is placed in the right femoral artery for tl10se animals
not undergoing behavioral testing or tail artery for those animals undergoing behavioral testing to monitor arterial blood pressure
and blood gases. Brain temperature is indirectly measured by a them1istor placed in the left temporalis muscle and maintained
at a normothe1mic (37oC) level prior and subsequent to TBJ. Rectal temperature is also maintained at nom1othem1ic levels. After
intubation, the animal is com1ected to a respirator and ventilated witl1 0.5-1% isoflurane in a mixture of70% nitrous oxide m1d
30% oxygen. The animal is paralyzed with rocuronium for mechanical ventilation to maintain arterial blood gases within normal
limits. The fluid percussion (F-P) device consists of a plexiglass cylindrical reservoir bounded at one end by a rubber-covered
plexiglass piston with the opposite end fitted with a transducer housing and a central injury screw adapted for the rat’s
skull. The entire system is filled with 37oC isotonic saline. The (aseptic) metal injury screw is next firn1ly connected to the
plastic injury tube of the intubated and anesthetized rat. The injury is induced by the descent of a metal pendulum striking the
piston, thereby injecting a small volume of saline epidurally into the closed crm1ial cavity and producing a brief displacement
(18 msec) of neural tissue. The amplitude of the resulting pressure pulse is measured in atmospheres by a pressure transducer
and recorded on a PowerLab chart recording system. Sham animals will undergo all surgical procedures but are not subjected to
the F-P pulse. In proposed studies, a mild (1.4-1.6 atm) injury will be studied. Following injury, catheters are removed and the
incisions are stapled/sutured closed. Anesthesia is discontinued and animals awake approximately 30 min after injury and are placed
in an individual cage supplied with food and water ad libitum until termination of the study.

 

    	 

    	 	 	 

    

 

Post-Exposure
husbandry

 

All
animals will be monitored for respiratory rate, heart rate m1d blood oxygen saturation using a STARR Life Sciences, Corp., and
Pulse oximetry before and after the exposure and for the entire recovery pe1iod after the exposure. If animals show signs of extreme
pain or that they may not recover after blast exposure, the Veterinarian will examine the animal. Animals will be closely observed
for signs of pain to include vocalization, in appetence, aggression, guarding, and extreme agitation. The animal may or may not
be euthanized based on the veterinarim1’s recommendation. To avoid potential pain reaction, ketoprofen will be given immediately
after the blast exposure. A pain assessment will be applied beginning immediately after recovery from anesthesia. The major indices
to assess will be: activity, physical appearance, vocalizing, grinding teeth, feeding/drinking behavior and physiological signs
such as respiratory rate, heart rate and oxygen saturation). If any of the indicators suggest the animal is still experiencing
pain, then higher doses will be delivered or if intractable, animals will never be left in pain and the Vete1inarian may decide
to euthanize the rat. Pain relief will be as required. Collection of functional measures can be postponed to the next day if animals
display pain levels that prevent testing. At that time, the animal’s status will be reevaluated and testing may commence
or again be delayed. Once functional and cognitive measures are complete on surviving blast-exposed animals, they will be euthanized
for collection of tissues, body fluids and blood.

 

Medicine
Dosing

 

The
SP will be given via IP injection 2 hours after exposure. This dose will be repeated daily for 7 additional days.

 

    	 

    	 	 	 

    

 

Behavioral
Tests

Sensorimotor
Testing:

 

Spontaneous
Forelimb Use: This test, described by Schallert and Lindner (1990), assesses forelimb use during voluntary, spontaneous activity
by evaluating the propensity of animals to adduct their forelimbs while rearing or standing. Animals are videotaped in a clear
plastic cylinder for 5 minutes. The videotapes are scored in terms of forelimb-use asymmetry during vertical movements along the
wall of the cylinder and for landings after a rear: (a) independent use of the left or right forelimb for contacting the wall
of the cylinder during a full rear, to initiate a weight-shifting movement or to regain center of gravity while moving laterally
in a vertical posture along the wall; Wa11 lands/movements and floor lands are each expressed in ten11S of (a) percent use of
the ipsilateral (non-impaired) forelimb relative to the total number of ipsilateral and contralateral placements. During a rear,
the first limb to contact the wall with clear weight support (without the other limb contacting the wall within 0.5 sec) is scored
as an independent wall placement for that limb. Limb use ratio is calculated as contralateral/(ipsilateral + contralateral).

 

Cognitive
Testing

 

The
analysis of cognitive function involves an assessment of spatial navigation using the water maze. Experiments that are primarily
directed at assessing the activity of animals at numerous time points following TBI (such as when assessing the efficacy of therapeutic
treatments designed to lessen the consequences of TBI) rely primarily on “acquisition” paradigms involving the simple
place task and working memory task, in which the animals are required to learn a new platfom1 location during each test session.
This protocol does not involve pretraining or testing in the water maze prior to surgery.

 

General
Procedures: The water maze used in this laboratory is a round pool (122 cm diameter; 60 cm deep) filled with water at 25oC, and
rendered opaque by adding two pounds of white, non-toxic paint. The maze is located in a quiet, windowless room, with a variety
of distinct, extramaze cues. Four points on the rim designated as north (N), cast (E), south (S), and west (W), serve as starting
positions and divide the maze into four quadrants. A round platform (10 cm in diameter) is placed 1.5 cm beneath the surface of
the water, at a location that varies according to the requirements of the task (see below). The animal’s movement is videotaped
with a CCD video which records the swim path. This animal’s swim path is then analyzed with the Ethovision (Noldus) software
program. This program determines path length, latency to reach the platfom1 (in seconds), time spent in each quadrant of the water
maze and swim speed.

 

Hidden
Platform Task: The platfom1 is located in the northeast quadrant of the maze. Each animal receives four 60 sec. trials each day.
If the rat successfully locates the platfom1 it is allowed to remain for 10 seconds; otherwise, it is put on the platform for
a period of IO seconds. Inter-trial intervals are two to four minutes, during which rats are placed under a heat lamp. Animals
are tested after sensorimotor testing.

 

Probe
Trial: This consists of removing the platfom1 and releasing the animal from the west position and videotaping the animal’s
swim pattern for 60 seconds. An animal that is not impaired should spend most of the time swimming in the quadrant that previously
contained the hidden platform.

 

    	 

    	 	 	 

    

 

Working
Memory Task

 

For
the working memory task, the animal is given 60 seconds to find a submerged (non-cned) platfom1. If the rat fails to find the
platform within 60 seconds, the animal is placed on the platfom1 for IO seconds. Five seconds following trial one for the same
rat, a second identical trial is conducted. Rats are placed under a heat lamp for 4 minutes between each paired trial. After running
the group of rats as above, the platform is moved to the next location of the maze and the procedure is repeated with this location.
Five paired trials are given for each rat on each day.

 

Novel
Object Recognition

 

A
Novel Object Recognition task will be conducted in an open field arena with two different kinds of objects. Both objects will
be consistent in height and volume, but different in shape and appearance. Animals will be allowed to explore an empty arena and
during habituation, the animals will be exposed to this familiar arena with two identical objects placed at an equal distance.
The following day the animals will explore the open field in the presence of the familiar object and a novel object to test long-term
recog1iition memory. The time spent exploring each object and the discrimination index percentage will be recorded.

thresholds will be determined by auditory brainstem response via subcutaneous platinum needle electrodes placed at the vertex
(reference), light mastoid (negative) and the left hind limb. Digitally generated stimuli will consist of 1024 specific frequency
tone bursts at between 3 and 30 kHz with a trapezoid envelop of 5 ms overall duration. The trapezoid will be presented at a 3
ms plateau with 1ms rise and fall. The stimulus will be routed through a computer-controlled attenuator to an insert earphone
(Etymotic Research ER-2). The sound delivery tube of the insert earphone will be positioned about 5 mm from the tympanic membrane.
The output of the insert earphone will be calibrated by measuring the sound pressure level at a position 4-5 mm away from the
tympanic membrane. Animals will be placed in a plastic restraint tube during the forty-five minute, recording procedure. The electrical
response from the recording electrode will be amplified (100,000 x), filtered (100-3000 Hz) and fed to an ND conve1ter
on a signal processing board in the computer. Eight hundred to twelve hundred samples will be averaged at each level. Stimuli
will be presented at the rate of 16/sec and the stimulus level will be varied in 10 dB descending steps, until threshold is reached,
then a 5 dB ascending step to confirm. Threshold is defined as the mid-point between tJ1e lowest level at which a clear response
is seen and the next lower level where no response is seen. ABR is determined as a reproducible wave II response.

 

Vestibular
Evoked Myogenic Potentials (VEMP)

 

Vestibular
Myogenic Potentials (cVEMP) to test balance function will be measured before trauma
and at multiple time points post-trauma, up to 30 days. The measurements will be made with subcutaneous needle electrodes attached
to a pre-amplifier and a data acquisition system (Intelligent Healing Systems). Vestibular evoked myogenic potentials (VEMP) are
measured by subdermal electrodes placed in neck muscles in response to acoustic stimuli that stimulate the saccule. Following
the recordings, animals will be observed every 15 mins pe1iod for recovery from the anesthesia and once ambulatory once every
hour until they are fully recovered from tJ1e anesthesia and are behaving normally. The residual function in control animals will
be compared with treated animals. Potential side effects such as balance problems, rotating behaviors and pain will be monitored.
In acute studies, animals will be euthanized at 24, 48 and 72 hours (immunohistochemical and gene expression) or at the conclusion
chronic testing (histological analysis). The critical time for intervention, dose-response and optimal duration of treatment will
be established.

 

    	 

    	 	 	 

    

 

Histopathology

 

Tissue
harvesting:

 

After
behavioral testing, animals will be euthanized and tissues collected in two ways:

 

1.       For
histology, under over dose of ketamine (150 mg/kg) and xylazine (10 mg/kg) or isoflurane anesthesia, rats will be transcardially
perfused with saline and followed with 4% parafomaldehyde. The head, liver and kidneys will be removed and post fixed in the same
fixative. Either decalcified heads or extracted brains will be used for histopathological analysis..

 

2.       For
Mass Spectrometric Imaging, under over dose of ketamine (150 mg/kg) and xylazine (IO mg/kg) or isoflurane anesthesia, rats will
be transcardially perfused with saline to clear the blood. The brains are then removed rapidly and frozen in isopentane cooled
with solid CO2 (dry ice).

 

3.       For
molecular biology, under over dose of ketamine (150 mg/kg) and xylazine (JO mg/kg) or isoflurane anesthesia, rat will be decapitates,
tissue such as brain and kidney/liver will be quickly removed and frozen in liquid nitrogen, and stored in -80° C until use..

 

Tissue
Processing Histopathology

 

After
appropriate survival times, sham and traumatically exposed rats are anesthetized with sodium pentobarbital (100 mg/kg, i.p.) and
perfused transcardially with 0.1 M PBS, followed by paraformaldehyde-lysine-periodate fixative. The intact heads are post-fixed
in 4% paraformaldehyde for 24 h at RT, decalcified in 10% f011nic acid to chemical l testing criterion and neutralized in overnight
5% sodium sulfate. After embedding in paraffin, sections are cut at 8-10 111 in the horizontal plane. Every 25th section is stained
with hematoxylin and eosin for standard histopathological analysis. For immunohistochemistry, sets of sections are incubated sequentially
in the following solutions at RT: 5% normal donkey serum (NDS) in 0.1 M PBS for 2 h; primary antisera in 0.1 M PBS for 72 h and
0.1 M PBS for 15 min. The antibodies are then visualized with either ABC peroxidase or immunofluorescence method. Primary antibodies
employed in decalcified heads with blast exposure include both neuronal and non-neuronal markers such as superoxide dismutase
2, interleukin 8 receptor, chemokine CXC motif receptor 3 angiopoietin 1, Vascular Endothelial Growth Factor A, TNF-alpha, and
matrix metalloproteinase 2.

 

    	 

    	 	 	 

    

 

Mass
Spectrometric Imaging

 

The
anin1als are euthanized 1, 3 or 7 day post injury. Under ketamine/xylazine (100 mg/kg; 10 mg/kg) anesthesia, the chest of each
rat is opened and the head perfused through a catheter placed in the ascending aorta with 50 to 100 ml of phosphate buffered saline
at room temperature, allowing blood to flush from the head through an opening in the superior vena cava. When the perfusate is
largely clear of blood, the skull is carefully opened and the brain dissected. After removing meninges, each brain is rapidly
frozen in a small beaker containing about 30 ml of cold isopentane pre-cooled by immersion of the beaker in solid CO2, then removed,
wrapped individually in aluminum foil and stored at -80 °C until sectioned. The brains are sectioned in the coronal plane
at a thickness of 18 microns using a cryostat (Leica Microsystems CM3050S, Bannockburn, IL). Tissue sections are implanted with
silver nanoparticles (AgNP) 6 nm in diameter, using a nanoparticle implanter (Ionwerks, Houston, TX). A The1mo Scientific MALO!
LTQ-XL-Orbitrap (Thern10 Fisher Scientific, San Jose, CA) and Xcalibur software are used for used for matrix assisted laser desorption
(MALDI) mass spectrometry imaging (MSI) data acquisition. Images of coronal sections are constructed from data collected in positive
and negative ion mode, using a custom software package (Ionwerks, Houston, TX), which exports MS peak data for further statistical
analysis in MATLAB.

CLINICAL
STUDIES

 

The
acute and chronic effects of mild to moderate TB! are well documented but poorly understood. Major obstacles include: inadequate
models that address the complex combination of antecedent factors and downstream recovery pathways, the lack of sensitive biomarkers
and diagnostic technologies, and difficulty tracking the multi factorial array of cognitive, affective, neurologic, and behavioral
clinical endpoints. The first phase of the Scythian Bioscience (SB) Project will focus on the pre-clinical studies, piloting phase
of the proposed outcome measures, and the translational project, the latter providing the transition from pre-clinical to the
SB clinical study beginning in Year 3. Significant efforts will be directed towards narrowing and refining the most sensitive
outcomes from 9 domains shown to be, in varying degrees and combinations, significa11tly impacted in mild to moderate TBI: cognitive,
behavioral, psychosocial, sleep, pain, sensory/motor, cardiovascular, inflammatory biomarkers, and imaging parameters . During
this time, we will also seek to clarify a11d address metl1odologieal shortcomings in the literature, design novel outcomes that
circ1mwent these shortcomings, pilot the outcome measures on nom1al, and two groups of TBI patients (acute and chronic), and propose
a study methodology to begin in Year 3 to test the SB product. Another important aim of Year 2 will be to carry out the translational
component of our proposal, using a transgenic tau mouse model. This project will require a close collaboration between preclinical
and clinical investigators, with the goal of gathe1ing critical data in the piloting phase in order to infom1 and insure direct
application from the expe1imental studies to the fully powered clinical trial beginning in Year 3.

 

Scope
of Work

Summary
of the proposed objectives for Years 1 & 2: 

 

First
6 Months: July-December, 2016

 

I.     Identify
the key questions and direction for clinical arm of the proposed study.

 

Major
Objective: Rigorous review of available literature addressing (1) cannabinoid treatment of neurological disorders; (2) endocannabinoid
system and neuroinflammation; (3) Cannabinoids in the treatment of TB!; (3) safety and toxicity of cannabinoids; (4) mmethodological
biases and weaknesses in RCTs and other trials; propose a clinical trial design to avoid these shortcomings.

 

II.    Identify
outcomes

 

Major
objective: To identify the most sensitive tools to assess outcomes in 9 domains specifically relevant for TBI. Each domain
will be examined separately, with one or more assessment tools that will be evaluated in the proposed pilot studies (Year 2).
Each outcome will be examined for its sensitivity as a marker of cognitive, behavioral and physical changes associated with concussion
and for its feasibility for the large clinical trial incorporating the Scythian Biosciences product (SB) (Year 3). Below is a
brief description of the potential outcomes associated with each domain, which in tum, will be further refined as the study progresses
and we accw1mlate preclinical data.

 

A.     Cognitive:
emphasis on disruption of decision making, working memory and
attention, memory and learning, processing speed

 

B.
    Behavioral: Emotion/affective
assessment, mood measures: depression, anxiety, apathy and suicidality.

 

    	 

    	 	 	 

    

 

C.    Psychosocial
Outcomes: employment status, social interactions, life satisfaction,
QoL alterations.

 

D
    Sleep: sleep
fragmentation, slow wave sleep and circadian rhythm disruption

 

E.
    Pain: Pain: Headaches,
generalized pain syndromes

 

F.

I.
Design and execute pilot studies-

Major
Objective: The pilot studies described below will collectively:

 

-provide
evidence to justify a larger clinical trial.

-insure
accurate dosing conversion from animals to humans.

-develop
statistical models to disentangle syn1ptoms of TBI from potential adverse treatment effects.

-to
model the cont1ibution of identifiable risk factors in TBI outcome in masking potential benefit from SB product.

-to
develop models for parsing out placebo effects from treatment effects.

 

    	 

    	 	 	 

    

 

The
three pilot projects are:

 

A.     
Neurobehavioral assessment of proposed test batte1y
on normal subjects- test tolerability, length of assessment and order effects (n=20).

B.      Administer
the proposed assessment battery to acute (n=I 0) and chronic (n=IO) TBI sample test tolerability, fatigue factor, length of assessment
and order effects.

C.      Dosing
response pilot on TBI and normal Ss- safety and efficacy studies. Note: the specific dosing will depend on outcome of pre-clinical
study data.

 

Year
2: Jan 1, 2018 -December 31, 2018

 

	I.	Design
                                         and implement translational study

 

Major
Objective: To design translational studies focusing on parallel pre-clinical and clinical paradigms providing direct application
from basic science to human health.

 

Plan:
Work in collaboration with Drs. Dietrich, Hoffer (Michael and Barry Hoffer), Balaban, Bramlett, Gardner, Greig on translational
studies. We propose to utilize a transgenic tau model and parallel clinical measures to examine the influence of trauma, with
and without SB product, on specific inflammatory biomarkers that may be indicative negative healtl1 outcomes.

 

	II.	Formulate
                                         clinical study methodology

 

Major
objective: Follow CONSORT guidelines, propose a randomized, placebo controlled, cross over trial utilizing pilot data to enhance
clinical design.

 

The
proposed methodology will be adapted from the best available literature on TB! outcomes, our pilot study data on the clinical
study outcomes in 110111ml, acute and chronic TB! subjects, dose response pilot data and, in order to insure a safe and
efficacious clinical project, careful consideration of published studies examining cannabinoid treatment of neurological disorders,
the endocannabinoid system and literature on safety and toxicity of cam1abinoids.

 

YEAR
2 : Budget justification Clinical

 

Both
compounds HU21 l (HU) and Cannabadiol (CB) will be purchased from Tocris Pharmaceuticals. HU costs $375/10 mg and CB costs $629/50
mg. During !lie second year of clinical work the clinical working group will undertake a safety and basic efficacy study. Guided
by the work of the basic science group the clinical group plans on testing 40 patients receiving the medicines at the effective
dose of 10mg/kg for CB and I mg/kg HU for a total dose of 60 mg CB and 6 mg HU. HU 21 I will be tested on 10 patients alone
who each will receive 7 doses at for a total cost of$10,000. CB alone will be tested on 10 patients alone who will receive 7 doses
at $760/dose each for total cost of$40,000. The combination of the two medicines will be utilized on 20 trial patients each of
who will receive 7 doses each at$ I 000 per dose for a total cost of$ I 40,000. This produces a clinical cost of $190,000 for
clinical work in year two.
