See “Business – Disc/Spine Program – License” below.
(b)
Business
General
We
are a life sciences company focused on the development of regenerative medicine products and therapies using cell and tissue protocols,
primarily involving adult (non-embryonic) stem cells. Our two core developmental programs, as described below, relate to the treatment
of disc/spine disease and metabolic disorders:
We
have also licensed an investigational curved needle device designed to deliver cells and/or other therapeutic products or material to
the spine and discs (and other parts of the body). We anticipate that FDA approval or clearance will be necessary for this device prior
to commercialization. We do not intend to utilize this device in connection with our contemplated Phase 2 clinical trial with regard
to BRTX-100. See “Curved Needle Device” below.
The
patents and patent applications for the Disc/Spine Program, the ThermoStem Program and the curved needle device are listed
below under “Technology; Research and Development.”
Overview
Every
human being has stem cells in his or her body. These cells exist from the early stages of human development until the end of a person’s
life. Throughout our lives, our body continues to produce stem cells that regenerate to produce differentiated cells that make up various
aspects of the body such as skin, blood, muscle and nerves. These are generally referred to as adult (non-embryonic) stem cells. These
cells are important for the purpose of medical therapies aiming to replace lost or damaged cells or tissues or to otherwise treat disorders.
Regenerative
cell therapy relies on replacing diseased, damaged or dysfunctional cells with healthy, functioning ones or repairing damaged or diseased
tissue. A great range of cells can serve in cell therapy, including cells found in peripheral and umbilical cord blood, bone marrow and
adipose (fat) tissue. Physicians have been using adult stem cells from bone marrow to treat various blood cancers for more than 65 years
(the first successful bone marrow transplant was performed in 1956). Recently, physicians have begun to use stem cells to treat various
other diseases. We intend to develop cell and tissue products and regenerative therapy protocols, primarily involving adult stem cells,
to allow patients to undergo cellular-based treatments.
We
are concentrating initially on therapeutic areas in which risk to the patient is low, recovery is relatively easy, results can be demonstrated
through sufficient clinical data, and patients and physicians will be comfortable with the procedure. We believe that there will be readily
identifiable groups of patients who will benefit from these procedures. We also believe that these procedures will be significantly less
expensive than the most common surgical procedure alternatives and will compare favorably, over the long-term, to conservative treatment
costs which may persist for years.
Accordingly,
we have focused our initial developmental efforts on cellular-based therapeutic products and clinical development programs in selective
areas of medicine for which the treatment protocol is minimally invasive. Such areas include the treatment of the disc and spine and
metabolic-related disorders. Upon regulatory approval, we will seek to obtain third party reimbursement for our products and procedures;
however; if we are not successful, patients may be required to pay for our products and procedures out of pocket in full and without
the ability to be reimbursed by any governmental and other third party payers, which would adversely impact our prospects.
We
have undertaken research and development efforts in connection with the development of investigational therapeutic products and medical
therapies using cell and tissue protocols, primarily involving adult stem cells. See “Disc/Spine Program,” “Metabolic
Brown Adipose (Fat) Program” and “Curved Needle Device” below. As a result of these programs, we have five United States
patents, nine foreign patents, three United States patent applications, and eight foreign patent applications related
to research regarding our ThermoStem Program, we have obtained licenses for eleven United States patent applications related to our Disc/Spine Program and we have obtained a license for one United States patent related to a curved needle device.
We
have established a research laboratory facility with Good Manufacturing Practice, or cGMP, capabilities to produce clinical grade products
and will seek to further develop cellular-based treatments, products and protocols, stem cell-related intellectual property, or IP, and
translational research applications. See “Laboratory” below.
We
have not generated any significant revenues to date. In November 2021, we completed a $23,000,000 public offering of our securities.
Such funds are sufficient for us to complete our Phase 2 clinical trial investigating the use of BRTX-100 in the treatment
of chronic lower back pain arising from degenerative disc disease, as further described in this section, as well as to continue our pre-clinical
research and development efforts with respect to our ThermoStem Program and to satisfy our current working capital needs; however,
the implementation of our business plan, as discussed below, will require the receipt of additional financing to fund our research and
development efforts, including our contemplated Phase 3 clinical trial with regard to BRTX-100 and our contemplated clinical trials
relating to our ThermoStem Program, and otherwise fund our operations. We intend to seek to raise capital through investment
bankers and from biotech funds, strategic partners and other financial institutions. We anticipate that we will require approximately
$35,000,000 in additional financing to complete our contemplated Phase 3 clinical trial investigating the use of BRTX-100
(assuming the receipt of no revenues from operations). We will also require a substantial amount of additional funding to implement our
other programs described in this section, and fund general operations. No assurance can be given that the anticipated amount of required
funding is correct or that we will be able to accomplish our goals within the timeframes projected. In addition, no assurance can be
given that we will be able to obtain any required financing on commercially reasonable terms or otherwise. If we are unable to obtain
adequate funding, we may be required to significantly curtail or discontinue our proposed operations.
Disc/Spine
Program
General
Among
the initiatives that we are currently pursuing is our Disc/Spine Program, with our initial product candidate being called BRTX-100.
We have obtained a license (see “License” below) that permits us to use technology for adult stem cell treatment of
disc and spine conditions. The technology is an advanced stem cell culture and injection procedure into the intervertebral disc, or IVD,
that may offer relief from lower back pain, buttock and leg pain, and numbness and tingling in the leg and foot.
Lower
back pain is the most common, most disabling, and most costly musculoskeletal ailment faced worldwide. According to a 2016 market report
from Trinity Partners, a global life sciences consulting firm, of the 250 million American adults, nearly 25 million have chronic lower
back pain of which approximately 12 million have been diagnosed with and treated for disc degeneration and approximately 5.6 million
have pain caused by a protruding or injured disc. We believe that between 500,000 and one million invasive surgical procedures are performed
each year to try to alleviate the pain associated with these lower back conditions and that such procedures cost approximately $40 billion.
Clinical studies have documented that the source of the pain is most frequently damage to the IVD. This can occur when forces, whether
a single load or repetitive microtrauma, exceed the IVD’s inherent capacity to resist those loads. Aging, obesity, smoking, lifestyle,
and certain genetic factors may predispose one to an IVD injury. Current surgical approaches to back pain are extremely invasive (often
altering the spine’s biomechanics unfavorably and predisposing it to further disc degeneration) and are associated with unacceptably
low success rates (with a second operation occurring 10% to 20% of the time). In addition, current surgical approaches are costly with
spinal fusion surgery costing approximately $110,000, discectomy costing approximately $20,000 to $50,000 and disc replacement surgery
costing approximately $80,000 to $150,000. Even conservative treatments can be costly, with oral medications costing between $1,000 and
$2,000 per year, injection treatments costing approximately $8,000 per year and physical therapy costing approximately $20,000 annually.
We anticipate that the cost of a single treatment using BRTX-100 will compare favorably to conservative treatments which may continue
for years and will be less expensive than the most common surgical procedures.
While
once thought to be benign, the natural history of lower back pain is often one of chronic recurrent episodes of pain leading to progressive
disability. This is believed to be a direct result of the IVD’s poor healing capacity after injury. The IVD is the largest avascular
(having few or no blood vessels) structure in the body and is low in cellularity. Therefore, its inherent capacity to heal after injury
is poor. The clinical rationale of BRTX-100 is to deliver a high concentration of the patient’s own cultured MSCs into the
site of pathology to promote healing and relieve pain.
We
have developed a mesenchymal stem cell product candidate, BRTX-100, derived from autologous (or a person’s own) human bone
marrow, cultured and formulated, in a proprietary method, specifically for introduction into a painful lumbar disc. The product candidate
was developed utilizing in part the license described below under “License.” As described below under “BRTX-100”
and “Production and Delivery,” BRTX-100 is a hypoxic (low oxygen) stem cell product developed through a culturing
process. In order to enhance the survivability of our bone marrow-derived MSCs in the avascular environment of the damaged disc, BRTX-100
is designed to expand under hypoxic conditions. This process is intended to result in a large cell count population with enhanced
viability and therapeutic potential following injection into the injured disc.
We
submitted an IND application to the FDA to obtain authorization to commence a Phase 2 clinical trial investigating the use of BRTX-100,
our lead cell therapy candidate, in the treatment of chronic lower back pain arising from degenerative disc disease. We received such
authorization from the FDA in February 2017. We have commenced our Phase 2 clinical trial through the execution of a CRO agreement with
PRC Clinical, the commencement of clinical trial site identification, the purchase of manufacturing equipment and the expansion of our
laboratory to include capabilities for clinical production. We believe that, based upon our periodic reports to the FDA as to the commencement
of the clinical trial, the existing IND remains effective.
In
addition to developing BRTX-100, we may also seek to sublicense the technology to a strategic third party, who may assist in gaining
FDA approval for a lumbar disc indication, or third parties for use in connection with cellular-based developmental programs with regard
to disc and spine related conditions.
We
have established a laboratory, which includes a clean room facility, to perform the production of cell products (including BRTX-100)
for use in our clinical trials, for third party cell products or for general research purposes. We may also use this laboratory to develop
our pipeline of future products and expand our stem cell-related IP. See “Laboratory” and “Technology; Research and
Development” below.
In March 2022, a United States
patent related to BRTX-100, was issued. We have been granted license rights with respect to the patent.
BRTX-100
Our
lead product candidate, BRTX-100, is an autologous hypoxic (low oxygen) cultured mesenchymal stem cell product derived from a
patient’s own bone marrow and formulated with a proprietary biomaterial carrier (platelet lysate) to increase potency, viability
and survivability. We have designed the cryopreserved sterile cellular product candidate to be provided in vials for injection into painful
lumbar discs. We anticipate the product candidate will be delivered using a standard 20 gauge 3.5 inch introducer needle and a 25 gauge
6 inch needle that will extend into the disc center upon delivery. Upon regulatory approval, we plan to provide training to medical practitioners
with regard to the approved injection procedure. It is anticipated that the delivery of the product candidate will be a 30 minute procedure.
Mesenchymal
stem cells used in BRTX-100 are similar to other MSCs under development by others; however, in order to enhance the survivability
of our bone marrow-derived MSCs in the avascular environment of the damaged disc, BRTX-100 is designed to expand under hypoxic
conditions for a period of approximately three weeks. This process is intended to result in an approximate 40 million cell count population
with enhanced viability and therapeutic potential following injection locally into injured spinal discs. Publications and scientific
literature have indicated that MSCs preconditioned in hypoxic environment show enhanced skeletal muscle regeneration properties and improved
impacts upon circulation and vascular formation compared to MSCs cultured under normoxic (normal oxygen) conditions.
In
August 2018, the Journal of Translational Medicine published the results of our study evaluating the benefits of long-term hypoxic
culturing of human bone marrow-derived MSCs.
In September 2021, we were
awarded a National Institutes of Health Small Business Technology Transfer (STTR) Phase 1 grant for $256,000 to evaluate the therapeutic
effects on our hypoxic cultured bone marrow derived mesenchymal stem cells (BRTX-100) after encapsulation with a PEG-peptide hydrogel.
The work is being done in collaboration with Washington University of St. Louis.
Production
and Delivery
The
production of our product candidate, BRTX-100, begins with the physician collecting bone marrow from the patient under local anesthesia.
Peripheral blood is also collected from the patient. The physician will then send the patient’s bone marrow and blood samples to
our laboratory (or a contract laboratory) for culturing and formulation. The hypoxic culturing process is intended to result in the selection
of a cell population that is suitable for an improved possibility of survival in the internal disc environment. We anticipate that the
cell culturing process and product formulation will take approximately three weeks, with an additional two weeks required for quality
control testing required to meet product release criteria. We will then send the therapeutic cryopreserved stem cells (BRTX-100)
in a sterile vial back to the physician’s offices where it will undergo a controlled thaw prior to the procedure. The price structure
for the procedure and our services has not been determined and no assurances can be given as to the effect that such price structure
will have on the marketability of such procedure and services. The following illustrates the process:
License
Pursuant to our license agreement
with Regenerative Sciences, LLC, or Regenerative, that became effective in April 2012, or the Regenerative License Agreement, we obtained,
among other things, a worldwide (excluding Asia and Argentina), exclusive, royalty-bearing license from Regenerative to utilize or sublicense
a certain method for culturing cells for use in our developmental program involving disc and spine conditions, including protruding or
painful discs and the treatment of avascular zones. The investigational technology that has been licensed is an advanced stem cell culture
and injection procedure that may offer relief from lower back pain, buttock and leg pain, and numbness and tingling in the leg and foot.
Pursuant to the Regenerative License Agreement, we also obtained a worldwide, exclusive, royalty-bearing license from Regenerative to
utilize or sublicense a certain investigational curved needle device for the administration of specific cells and/or cell products to
the disc and/or spine (and other parts of the body). It will be necessary to advance the design of this investigational device to facilitate
the delivery of substances, including living cells, to specific locations within the body and minimize the potential for damage to nearby
structures.
The Regenerative License Agreement
provided for the requirement that we complete our Phase 2 clinical trial by a certain date in order to maintain the exclusive
nature of the licenses. Such date has passed and accordingly our rights are non-exclusive. We are currently in negotiations with Regenerative
with regard to a possible reinstatement of the exclusive nature of the licenses. No assurances can be given in this regard. The lack
of exclusivity will not impact our ability to conduct our Phase 2 clinical trial with regard to BRTX-100. The Regenerative
License Agreement also provides for a royalty-bearing sublicense of certain aspects of the technology to Regenerative for use for certain
purposes, including in the United States and the Cayman Islands. Further, the Regenerative License Agreement requires that Regenerative
furnish certain training, assistance and consultation services with regard to the licensed technology. The patents that are the subject
of the Regenerative License Agreement have been assigned to Regenexx, LLC which we have been advised by Regenerative is an affiliate
of Regenerative.
Animal
Study
The
efficacy and safety of our product candidate, BRTX-100, has been tested in a degenerative intervertebral rabbit disc model. In
this study, 80 rabbits underwent surgery to create a puncture in the discs. Four weeks post-surgery, each rabbit had either contrast,
a biomaterial carrier or BRTX-100 injected into the discs. In order to study the biodistribution and efficacy of BRTX-100,
the rabbits were evaluated at day 56 and day 120.
The
key safety findings of the animal study are as follows:

Clinical
Trial
We
submitted an IND application to the FDA to obtain authorization to commence a Phase 2 clinical trial investigating the use of BRTX-100,
our lead cell therapy candidate, in the treatment of chronic lower back pain arising from degenerative disc disease. We have received
such authorization from the FDA. We have commenced our Phase 2 clinical trial through the execution of a CRO agreement with PRC Clinical,
the commencement of clinical trial site identification, the purchase of manufacturing equipment and the expansion of our laboratory to
include capabilities for clinical production.
The
following describes the Phase 2 clinical trial authorized by the FDA:
A
Phase 2 Prospective, Double-Blinded, Placebo Controlled, Randomized Study
● General
● 99 patients; randomized 2:1, BRTX-100 to control, 40 million cells/dose
● 10-20 clinical trial sites (we intend to utilize 15 clinical trial sites)
● Primary efficacy endpoint at 12 months
● Patient safety and efficacy follow up at 24 months
● Included subjects must have only one symptomatic diseased disc
● Primary Efficacy Endpoint
● Additional or Secondary Endpoints
● Clinical response at 12 months
In
December 2021, we entered into a Master Service Agreement with Professional Research Consulting Inc. d/b/a PRC Clinical, a contract research
organization, or CRO, specializing in clinical trial management, to conduct our Phase 2 clinical trial.
The
FDA approval process can be lengthy, expensive and uncertain and there is no guarantee that the clinical trial(s) will be commenced or
completed or that the product will ultimately receive approval or clearance.
As
an alternative to undertaking any necessary clinical trials ourselves, we may explore the licensing of our rights with
respect to our product candidate, BRTX-100, to a strategic partner. Such an arrangement could possibly eliminate or significantly
reduce the need to raise the substantial capital needed to commence and complete the clinical trials and undertake the commercialization
of BRTX-100 and would provide licensing-related revenue to us in lieu of product sales revenue. No assurance can be given that
any licensing agreement will be entered into, whether upon commercially reasonable terms or otherwise.
Defined
Health Report
In
March 2018, we engaged Defined Health, a business development and strategy consulting firm, to conduct an independent review of BRTX-100.
Defined Health has worked with many of the leading companies in the pharmaceutical, biotech and healthcare industries for over 25 years.
The
review was intended to collect informed, independent opinions regarding BRTX-100 among key opinion leaders, or KOLs (i.e., orthopedic
surgeons specializing in back and spine surgery with experience in stem cell therapy), who, upon studying applicable clinical material,
could offer opinions regarding the future therapeutic potential of BRTX-100.
As
noted in the Defined Health report, the KOLs indicated that stem cell therapies have great potential to treat chronic lumbar disc disease
and other therapeutic areas. The KOLs reacted positively to the value proposition of our product candidate, BRTX-100, and were
optimistic that the clinical data presented to date is likely to be mirrored in future clinical investigations. Given the opportunity,
the KOLs indicated that they would likely participate in a clinical trial should it be offered at their center and that they would recommend
the study to appropriately eligible patients. The report indicated that, if BRTX-100 were to be granted FDA approval, the KOLs
anticipate that it would be integrated into the standard of care for eligible chronic lumbar disc disease patients.
Similar
Therapies
Human
data from studies of therapies comparative to BRTX-100 have shown reduced pain, increased function, and an absence of significant
safety issues with a durable response, as shown below:

of such drugs (twice as much as second ranked Canada). In 2020, 91,000 persons in the United States died from overdoses.
Total
annual healthcare and lost productivity costs in the United States related to pain, including headache, back pain and neck pain, are
estimated to be $600 billion, which is twice the annual costs related to heart disease and greater than the combined annual costs related
to cancer and diabetes.
Metabolic
Brown Adipose (Fat) Program
Since
June 2011, we have been engaging in pre-clinical research efforts with respect to an investigational platform technology utilizing brown
adipose (fat) derived stem cells, or BADSCs, for therapeutic purposes. We have labeled this initiative our ThermoStem Program.
Brown
fat is a specialized adipose (fat) tissue found in the human body that plays a key role in the evolutionarily conserved mechanisms underlying
thermogenesis (generation of non-shivering body heat) and energy homeostasis in mammals - long known to be present at high levels in
hibernating mammals and human newborns. Recent studies have demonstrated that brown fat is present in the adult human body and may be
correlated with the maintenance and regulation of healthy metabolism, thus potentially being involved in caloric regulation. The pre-clinical
ThermoStem Program involves the use of a cell-based (brown adipose tissue construct) treatment for metabolic disease, such as
type 2 diabetes, obesity, hypertension and other metabolic disorders, as well as cardiac deficiencies. The diseases, disorders and syndromes
that may be targeted by our ThermoStem Program are as follows:
We
have had initial success in transplanting the brown adipose tissue construct in animals, and we are currently exploring ways to deliver
into humans. Even though present, BAT mass is very low in healthy adults and even lower in obese populations. Therefore, it may not be
sufficient to either naturally impact whole body metabolism, or to be targeted by drugs intended to increase its activity in the majority
of the population. Increasing BAT mass is crucial in order to benefit from its metabolic activity and this is what our ThermoStem
Program seeks to accomplish. We may also identify other naturally occurring biologics and chemically engineered molecules that may
enhance brown adipose tissue performance and activity.
Obesity,
the abnormal accumulation of white fat tissue, leads to a number of metabolic disorders and is the driving force behind the rise of type
2 diabetes and cardiovascular diseases worldwide. Pharmacological efforts to alter metabolic homeostasis through modulating central control
of appetite and satiety have had limited market penetration due to significant psychological and physiological safety concerns directly
attributed to modulating these brain centers. Adipose tissue is one of the largest organs in the human body and plays a key role in central
energy balance and lipid homeostasis. White and brown adipose tissues are found in mammals. White adipose tissue’s function is
to store energy, whereas BAT specializes in energy expenditure. As discussed in a 2020 article published in the International Journal
of Molecular Sciences, recent advancements in unraveling the mechanisms that control the induction, differentiation, proliferation,
and thermogenic activity of BAT, along with the application of imaging technologies for human BAT visualization, have generated optimism
that these advances may provide novel strategies for targeting BAT activation/thermogenesis, leading to efficacious and safe obesity
targeted therapies.
We
are developing a cell-based product candidate to target obesity and metabolic disorders using BADSCs. Our goal is to develop a bioengineered
implantable brown adipose tissue construct intended to mimic ones naturally occurring in the human body. We have isolated and characterized
a human multipotent stem cell population that resides within BAT depots. We have expanded these stem cells to clinically relevant numbers
and successfully differentiated them into functional brown adipocytes. We intend to use adult stem cells that may be differentiated into
progenitor or fully differentiated brown adipocytes, or a related cell type, which can be used therapeutically in patients. We are focusing
on the development of treatment protocols that utilize allogeneic cells (i.e., stem cells from a genetically similar but not identical
donor).
In
order to deliver these differentiated cells into target locations in vivo, we seeded BADSCs onto 3-dimensional biological scaffolds.
Pre-clinical animal models of diet-induced obesity, that were transplanted with differentiated BADSCs supported by a biological scaffold,
presented significant reductions in weight and blood glucose levels compared to scaffold only controls. We are identifying technology
for in vivo delivery in small animal models. Having completed our proof of concept using our BAT in small animals, we are currently
developing our next generation BAT. It is anticipated that this next version will contain a higher purity of BADSC and a greater percent
of functional brown adipocytes, which is expected to increase the therapeutic effect compared to our first generation product. In addition,
we are exploring the delivery of the therapeutic using encapsulation technology, which will only allow for reciprocal exchange of small
molecules between the host circulation and the BAT implant. We expect that encapsulation may present several advantages over our current
biological scaffolds, including prevention of any immune response or implant rejection that might occur in an immunocompetent host and
an increase in safety by preventing the implanted cells from invading the host tissues. We have developed promising data on the loading
of human stem cell-derived tissue engineered brown fat into an encapsulation device to be used as a cell delivery system for our metabolic
platform program for the treatment of type 2 diabetes, obesity, hyperlipidemia and hypertension. This advancement may lead to successful
transplantation of brown fat in humans. We are evaluating the next generation of BAT constructs that will first be tested in small animal
models. No assurance can be given that this delivery system will be effective in vivo in animals or humans. Our allogeneic brown
adipose derived stem cell platform potentially provides a therapeutic and commercial model for the cell-based treatment of obesity and
related metabolic disorders.

undertake additional preclinical animal studies in order to optimize delivery and explore the feasibility of targeting additional indications.
Such studies are planned to begin in 2022. Following the completion of such studies, if successful, we intend to file an IND with the
FDA and initiate a clinical trial. The FDA approval process can be lengthy, expensive and uncertain and there is no guarantee of ultimate
approval or clearance.
We
anticipate that much of our development work in this area will take place at our laboratory facility, outside core facilities at academic,
research or medical institutions, or contractors. See “Laboratory” below.
Curved
Needle Device
Pursuant
to the Regenerative License Agreement discussed under “Disc/Spine Program-License” above, we have licensed and further developed
an investigational curved needle device, or CND, that is a needle system with a curved inner cannula to allow access to difficult-to-locate
regions for the delivery or removal of fluids and other substances. The investigational CND is intended to deliver stem cells and/or
other therapeutic products or material to the interior of a human intervertebral disc, the spine region, or potentially other areas of
the body. The device is designed to rely on the use of pre-curved nested cannulae that allow the cells or material to be deposited in
the posterior and lateral aspects of the disc to which direct access is not possible due to outlying structures such as vertebra, spinal
cord and spinal nerves. We anticipate that the use of the investigational CND will facilitate the delivery of substances, including living
cells, to specific locations within the body and minimize the potential for damage to nearby structures. The investigational device may
also have more general use applications. In August 2015, a United States patent for the CND was issued to the licensor, Regenerative.
