Business
Overview
Tonix Pharmaceuticals (“Tonix” or the “Company”)
is a fully-integrated biopharmaceutical company developing and commercializing therapeutics to treat, and vaccines to prevent, disease
and alleviate suffering. Tonix’s primary focus is to obtain U.S. marketing authorization for TNX-102 SL (cyclobenzaprine HCl sublingual
tablet) 5.6 mg (2 x 2.8 mg tablets) for the management of fibromyalgia (“FM”) from the U.S. Food and Drug Administration (“FDA”).
The FDA assigned a prescription drug user fee act (“PDUFA”) goal date of August 15, 2025, for a decision on marketing authorization
for TNX-102 SL. In addition, we market two FDA-approved, prescription products for the treatment of acute migraine, and we are developing
a robust pipeline of potential new products.
Our pipeline has been generated from internal discovery, as well as licenses,
acquisitions and collaborations with academic institutions and non-profit organizations. Our development portfolio is focused on central
nervous system (“CNS”), disorders, but also consists of immunology, infectious disease and rare disease, product candidates.
The CNS portfolio includes small molecules and biologics to treat pain, neurologic, psychiatric and addiction conditions and includes
TNX-1300 which is in Phase 2 clinical development to treat cocaine intoxication partially funded by the U.S. National Institute on Drug
Abuse (NIDA). Our immunology portfolio includes TNX-1500 (anti-CD40L monoclonal antibody, or mAb), a biologic which has shown encouraging
results in Phase 1, which we plan to study to prevent organ transplant rejection and treat autoimmune diseases. Our infectious disease
portfolio includes TNX-801 (horsepox, live virus vaccine) a vaccine in development to prevent smallpox and mpox (formerly known as monkeypox)
and TNX-4200, which is a discovery program for broad spectrum antiviral drugs funded by a U.S Department of Defense contract for up to
$34 million over five years. TNX-4200 is being developed at our R&D facility located in Frederick, Maryland, (“RDC”),
which has biosafety level 2 (BSL-2) with BSL-3 components. Tonix’s product development candidates are investigational new drugs
or biologics and have not been approved for any indication.
Central
Nervous System (CNS) Pipeline
In October 2024, Tonix submitted a New
Drug Application (“NDA”) to the FDA for TNX-102 SL 5.6 mg for the management of FM, a proprietary sublingual tablet formulation
of cyclobenzaprine (“CBP”) designed for bedtime administration, and in December 2024, the FDA assigned a PDUFA goal date of
August 15, 2025, for a decision on marketing authorization for TNX-102 SL. FM is a chronic pain disorder characterized by widespread pain,
non-restorative sleep, fatigue and impaired cognition. TNX-102 SL is a centrally-acting, non-opioid analgesic designed for long-term bedtime
use and has been studied in three Phase 3 trials using TNX-102 SL 5.6 mg, two studies reported statistically significant results. The
FDA granted TNX-102 SL Fast Track designation in July 2024. We are preparing for a commercial launch of TNX-102 SL in the fourth quarter
of 2025, conditional on FDA approval.
In
March 2024, Tonix announced it selected two contract manufacturing organizations (CMOs), one of which is Almac Pharma Services,
a member of the privately owned Almac Group, as dual supply sources for the potential launch and commercialization of TNX-102
SL in the U.S.
4
TNX-102
SL also is being developed also as a treatment for acute stress reaction (“ASR”) and to prevent acute stress disorder
(“ASD”) and posttraumatic stress disorder (“PTSD”) under a physician-initiated Investigational New Drug
Application (“IND”) in partnership with the University of North Carolina (“UNC”) Institute for Trauma
Recovery.
In addition, TNX-102 SL has active INDs for the treatment of PTSD, agitation in
Alzheimer’s disease (“AAD”), alcohol use disorder (“AUD”) and the management of multi-site pain associated
with Long COVID (also known as Post-Acute SARS-CoV-2 or PASC). TNX-102 SL for AAD has been granted Fast Track designation by the FDA.
We are currently not actively studying TNX-102 SL in PTSD, AAD or AUD. Tonix is continuously evaluating further indications for which
TNX-102 SL could potentially provide benefit.
Another
CNS candidate in development is TNX-1300 (double-mutant cocaine esterase) which is in Phase 2 for the treatment of cocaine intoxication.
TNX-1300 has been granted Breakthrough Therapy designation by the FDA. TNX-1300 was licensed from Columbia University in 2019 after a
Phase 2 study showed that it rapidly and efficiently disintegrates cocaine in the blood of volunteers who received intravenous (i.v.)
cocaine. In August of 2022, we received a Federal Grant from the U.S. National Institute on Drug Abuse (“NIDA”) a part
of the U.S. National Institutes of Health (“NIH”) to advance the development of TNX-1300 as a treatment for cocaine intoxication.
Finally, we are developing TNX-1900 (intranasal potentiated oxytocin) for several CNS disorders through investigator-initiated studies. TNX-1900 is in development through investigator-initiated
studies at Massachusetts General Hospital (“MGH”) for the treatment of binge eating disorder (“BED”), adolescent
obesity, and bone health in pediatric autism. TNX-1900 is in development through an investigator-initiated study at the University of
Washington for the treatment of social anxiety disorder.
Immunology
Pipeline
Our lead candidate in the immunology pipeline is TNX-1500, an Fc-modified humanized
monoclonal antibody (“mAb”), directed against CD40-ligand (CD40L, also known as CD154). TNX-1500 was engineered to modulate
binding to Fc receptors with the goal of maintaining the activity of first-generation mAbs, yet with reduced risk of thrombotic complications.
TNX-1500 is being developed to prevent organ transplant rejection as well as to treat autoimmune conditions. Topline results from a Phase
1 single ascending dose escalation study at 3 mg/kg, 10 mg/kg and 30 mg/kg of TNX-1500 in healthy volunteers was reported in the first
quarter of 2025.
5
TNX-1500 has also been studied in combination with other immunosuppressive
agents in allogeneic transplants in non-human primates at MGH. In experiments at MGH, TNX-1500 is being studied as monotherapy or in combination
with other immunosuppressive agents in heart and kidney allogeneic organ transplants in non-human primates. Results from experiments in
kidney and heart transplants indicate that TNX-1500 appears to have comparable efficacy to historical experiments using the chimeric mouse/human
IgG1 version (5c8H1) of the anti-CD40L mAb 5c8.
TNX-1500 also is being studied in combination with other immunosuppressive
agents in xenogeneic organ transplants in non-human primates at MGH. In some of these studies, genetically engineered (“GE”)
pigs in baboon transplants were treated with cold perfused ischemia minimization and a novel co-stimulation-based immunosuppressive regimen
including TNX-1500. The results of these preclinical studies were encouraging and demonstrated the potential of GE pig hearts in the context
of a clinically applicable regimen. The multi-GE pigs were provided by eGenesis and Revivicor. Revivicor is a subsidiary of United Therapeutics.
Some results from the collaboration with MGH and eGenesis were published in the peer-reviewed journal, Nature in 2023. In
March of 2024, MGH announced the first GE pig kidney transplant into a living recipient supported in part by the pre-clinical work with
TNX-1500. Subsequently, several other GE pig kidney transplants have been performed. TNX-1500 treatment has not been used in any human transplant
recipient.
Our
immunology pipeline also includes TNX-1700, a recombinant Trefoil Factor Family 2 (“hTFF2-HSA”) fusion protein that
was licensed from Columbia University in 2019. TNX-1700 consists of TFF2 fused to human serum albumin and is a biologic
being developed to treat gastric and colorectal cancers by an immune-oncology mechanism, in combination with PD1 blockers, and
is in the preclinical stage of development. We presented data that show a murine version of TNX-1700 consisting of a fusion protein
with murine serum albumin was able to evoke anti-tumor immunity in the MC38 mouse model of colorectal cancer as monotherapy and
that TNX-1700 augmented the efficacy of anti-PD1 therapy in both the MC38 model and the CT26.wt mouse models of colorectal cancer. We
plan to request an INTERACT meeting with the FDA in 2025 to seek early guidance on program development.
Infectious
Disease Pipeline
Our
infectious disease portfolio includes vaccines based on our live virus vaccine or recombinant pox vaccine (“RPV”)
platform. Live virus vaccines are believed to protect against poor clinical outcomes of infectious diseases by eliciting T cell
responses in addition to antibody responses.
TNX-801, a live minimally replicative vaccine based on synthesized
horsepox, is in the pre-IND stage of development to protect against smallpox and mpox. In 2022 the WHO determined that the upsurge of
mpox Clade IIb constituted a public health emergency of international concern (PHEIC). Mpox Clade IIB subsequently has become endemic
in the U.S. mostly in populations of men who have sex with men. In August 2024, the WHO determined that the upsurge of mpox clade Ib in
a growing number of countries in Africa constituted a PHEIC. The WHO reaffirmed the PHEIC status of mpox clade Ib in February of 2025.
Mpox cases of the new clade Ib mpox have been detected in the United States and many other countries outside of Africa. Non-human primates
vaccinated with TNX-801 were protected from mpox clade Ia in studies reported in the first quarter of 2020 and published in the peer-reviewed
journal Vaccines in 2023.
In September 2024, at the DoD’s MHSRS conference and in October 2024 at the
World Vaccine Congress in Barcelona, Spain, Tonix presented new data on a potential mpox vaccine, TNX-801, demonstrating tolerability
and no evidence of spreading to blood or tissues, even at high doses, in immunocompromised animals. After a single-dose vaccination, TNX-801
prevented clinical disease and lesions, and also decreased shedding in the mouth and lungs of animals after a lethal challenge with clade
Ia monkeypox. These findings are consistent with TNX-801 inducing mucosal immunity and suggest TNX-801 may block forward transmission.
In September 2024, the Company also announced that the WHO’s preferred target product profile (“TPP”) aligns with the
characteristics of TNX-801. Key elements of the WHO draft TPP include single-dose, durable protection, administration without special
equipment, and stability at ambient temperature. Other potential beneficial characteristics include the ability to limit forward transmission,
use in case-contact vaccination strategies and suitability for use in immunocompromised individuals.
6
In October 2023, at the World Vaccine Congress - Europe, we reported that
the TNX-801 vaccine was shown to be greater than 10 to 1,000-fold more minimally replicative than older vaccinia-based smallpox vaccines
in both human primary cell lines and immunocompromised mice. In October 2024, at the World Vaccine Congress - Europe, we highlighted positive
preclinical efficacy data of TNX-801, demonstrating tolerability in immunocompromised animals and showed that TNX-801 is unable to spread
in blood or tissues in these animals, even at an approximately 100-fold higher dose than 20th century vaccinia vaccines in immune-comprised
mice. These data were published in the peer-reviewed journal mSphere in 2024.
TNX-801 also serves as the live virus vaccine platform for other infectious
diseases for which subsequent products will be designed by expressing other viral antigens in the horsepox vector. The company’s
Good Manufacturing Practice (“GMP”)-capable advanced manufacturing facility in Dartmouth, MA was purpose-built to manufacture
TNX-801. The GMP suites are currently decommissioned but are ready to be reactivated in case of a national or international emergency.
TNX-1800 is a live virus vaccine on the RPV platform that expresses the
SARS-CoV-2 spike protein from the ancestral Wuhan strain, which has shown encouraging results in non-human primates. In June 2024, the
Company announced preclinical data, demonstrating immunity and tolerability, during an oral keynote talk at the Vaccine Congress 2024.
Like TNX-801, TNX-1800 is a live minimally replicative vaccine based on horsepox that is believed to provide immune protection with better
tolerability than modern vaccinia viruses. TNX-1800 was selected by the NIH’s Project NextGen for inclusion in clinical trials as
part of a select group of next generation COVID-19 vaccine candidates with the intent to identify promising vaccine platforms. If Tonix
is able to provide TNX-1800 to NIH, they would conduct a Phase 1 trial and cover the full cost. However, Tonix has not prioritized the
production of TNX-1800, so it is uncertain whether or how quickly this project will progress. The COVID-19 vaccines approved for use in
the U.S. have provided significant health benefits to the vaccinated population; however, they have shown limitations in the durability
of protection conferred, and in their ability to block forward transmission. Live virus vaccines that protect against other viral diseases
by eliciting T cell responses have shown durability of protection that lasts years to decades, and some live virus vaccines have significantly
inhibited forward transmission. With respect to TNX-1800 vaccination, we reported positive efficacy data from animal challenge studies
using live SARS-CoV-2 in the first quarter of 2021. These data were published in the peer-reviewed journal Vaccines in 2023. In
this study, TNX-1800 vaccinated, SARS-CoV-2 challenged animals had undetectable SARS-CoV-2 in the upper airways, which we believe relates
to potential inhibition of forward transmission of this respiratory pathogen.
Tonix
is developing potential broad-spectrum antiviral drugs in three programs: CD45-targeted therapeutics (TNX-4200), cathepsin inhibitors
(TNX-3900) and viral glycan-targeted engineered biologics (TNX-4000). The DoD announced in December 2022 a plan to move beyond
a ‘one bug, one drug’ approach and are seeking broad-spectrum drugs since it may be hard to predict which or how many
viruses may be deployed on the battlefield.
In July 2024 Tonix was awarded a contract with a potential for up to $34
million over five years by the Defense Threat Reduction Agency (DTRA), an agency within the DoD. The objective of the contract is to develop
small molecule broad-spectrum antiviral agents for the prevention or treatment of infections to improve the medical readiness of military
personnel in biological threat environments. Tonix’s program will focus on optimization and development of its TNX-4200 program,
to develop an orally available CD45 antagonist with broad-spectrum efficacy against a range of viral families through preclinical evaluation.
The program is expected to establish physicochemical properties, pharmacokinetics, and safety attributes to support an IND submission
and to fund a first-in-human Phase 1 clinical study. Tonix plans to leverage previous research on phosphatase inhibitors, specifically
compounds that target CD45, to optimize lead compounds for therapeutic intervention of biothreat agents and provide the government with
a complete and cost-effective solution for a broad-spectrum medical countermeasure. Tonix’s premise is that partial inhibition of
CD45 will provide optimal antiviral protection while requiring lower plasma drug concentrations, a lower dose, and a better safety profile.
Tonix will utilize its state-of-the-art research laboratory capabilities,
including a Biosafety Level 3 (BSL-3) lab and an Animal Biosafety Level 3 (ABSL-3) facility at the RDC, as well as experienced personnel
in-house.
7
Rare
Disease Pipeline
Our rare disease portfolio consists of TNX-2900 (intranasal potentiated
oxytocin) for Prader-Willi syndrome (“PWS”), a genetic disorder characterized by complex symptoms. The formulation technology
for TNX-2900 was acquired from Trigemina, Inc. and licensed from Stanford University in 2020. The potentiated formulation includes magnesium,
which has been shown in animal studies to potentiate binding of oxytocin to the oxytocin receptor. The therapeutic technology was licensed
from Inserm, the French National Institute of Health and Medical Research. TNX-2900 was granted Orphan-Drug Designation by the FDA in
the second half of 2023 and the IND was cleared by the FDA in the fourth quarter of 2023 and received Rare Pediatric Disease Designation
on March 21, 2024. PWS, an orphan condition, is a rare genetic disorder of failure to thrive in infancy, associated with uncontrolled
appetite beginning in childhood with complications of obesity and diabetes. We have sponsored a research program at Inserm to study oxytocin
on suckling behavior in mice that have been engineered to express one of the PWS gene mutations.
Marketed
Medicines
Our
commercial portfolio consists of two FDA-approved prescription products for the treatment of migraine: Zembrace SymTouch (sumatriptan
injection) 3 mg and Tosymra (sumatriptan nasal spray) 10 mg. Zembrace SymTouch and Tosymra are both indicated for the treatment
of acute migraine with or without aura in adults. Zembrace SymTouch is the only branded sumatriptan autoinjector professionally
promoted in the United States and is designed for ease of use and favorable tolerability with a low 3 mg dose. Tosymra is a novel
intranasal sumatriptan product formulated with a permeation enhancer that provides rapid and efficient absorption of sumatriptan.
Tosymra was approved on the basis of bioequivalence to subcutaneous (s.c.) sumatriptan. Tonix Medicines is the only manufacturer
with both a branded injectable and nasal spray indicated for the acute treatment of migraine with or without aura in adults.
In
September 2024, Tonix announced that the United States Patent and Trademark Office (USPTO) issued U.S. Patent No. 12,097,183 to
the Company, claiming use of a pre-filled autoinjector comprising a composition of Zembrace® SymTouch® for treating migraines
via subcutaneous administration. This patent, excluding possible patent term extensions, is expected to fortify protection and
market exclusivity into 2036. Additionally, Tonix announced that the USPTO issued U.S. Patent No. 12,090,139 to the Company, claiming
a pharmaceutical composition, a method of treating migraine via intranasal administration, and an intranasal delivery system for
Tosymra®. This patent is expected to fortify protection and market exclusivity into 2030.
In
June 2024, the Company presented data at the 66th Annual Scientific Meeting of the American Headache Society (AHS) comparing real-world
data with real-world usage of non-oral migraine products with the most recent AHS consensus statement. This data stressed the
need for customizing treatment of migraine headaches to the needs of patients. Thus far, real world data show that conformity
with the guidelines and the consensus statement have yet to be achieved but has the potential to be increased. The data show the
use of non-oral drugs for treating an acute migraine attack was only 7% in 2012 and has decreased to below 4% in 2023, when the
potential need for such drugs is anticipated to be a more substantial percentage of migraineurs based on epidemiological data.
In 2024, Tonix Medicines launched a national educational campaign focusing on the link between migraine, gastroparesis, and the
need for non-oral acute migraine therapies.
Facilities
Relating to our
development programs, we own and operate the RDC in Frederick, Maryland consisting of one building totaling approximately 48,000
square feet. The RDC conducts research on CNS, immunology, and infectious disease candidates. The RDC facility is mostly biosafety
level 2 (BSL-2), with some components designated BSL-3. We also own an Advanced Development Center (“ADC”) located in
the New Bedford business park in Dartmouth, Massachusetts. This approximately 45,000 square foot BSL-2 facility is intended to
accelerate development, clinical and commercial scale manufacturing of live-virus vaccines and biologics to support clinical
trials. This facility was decommissioned in 2024 but Tonix has the ability to reactivate it should we choose to do so.

Strategy
Our
strategy is to use our integrated development and marketing capabilities to advance innovative programs across multiple therapeutic
areas through the drug development process, with the ultimate objectives of FDA approval and commercialization. The principal
components of our strategy are to:
9
Disease
and Market Overview
Our
product candidates address disorders that are not well served by currently available therapies or have no approved treatment which
represent large potential commercial market opportunities. Background information on the disorders and related commercial markets
that may be addressed by our product candidates in or nearing the clinical stage of development is set forth below.
Central
Nervous System
Fibromyalgia
(FM)
Fibromyalgia
is a common chronic pain disorder that is understood to result from amplified sensory and pain signaling within the central nervous
system, called central sensitization. Brain imaging studies have localized the functional disorder to the brain’s insular
and anterior cingulate cortex. Fibromyalgia afflicts more than 10 million adults in the U.S., the majority of whom are women.
Symptoms of fibromyalgia include chronic widespread pain, non-restorative sleep, fatigue, and brain fog (or cognitive dysfunction).
Other associated symptoms include mood disturbances, including depression, anxiety, headaches, and abdominal pain or cramps. Individuals
suffering from fibromyalgia often struggle with their daily activities, have impaired quality of life, and frequently are disabled.
Physicians and patients report common dissatisfaction with currently marketed products. Fibromyalgia is now recognized as the
prototypic nociplastic syndrome. Nociplastic pain is the third primary type of pain in addition to nociceptive pain and neuropathic
pain. Many patients present with pain syndromes that are combinations of the three primary types of pain. Nociplastic syndromes
can involve components of both central and peripheral sensitization. Fibromyalgia can occur without any identifiable precipitating
event. However, many fibromyalgia cases follow one or more precipitating event(s) including: chronic nociceptive or neuropathic
pain states; recovery from an infectious illness; a cancer diagnosis or cancer treatment; a metabolic or endocrine stress; or
a traumatic event. In the cases of recovery from an infectious illness, fibromyalgia is considered an Infection-Associated Chronic
Condition. In addition to fibromyalgia cases associated with other conditions or stressors, the U.S. National Academies of Sciences,
Engineering, and Medicine, has concluded that fibromyalgia is a diagnosable condition that occurs after recovery from COVID-19
in the context of Long COVID. Fibromyalgia is also recognized as a Chronic Overlapping Pain Condition, due to shared symptoms
with chronic fatigue syndrome/myalgic encephalomyelitis, irritable bowel syndrome, endometriosis, low back pain, post-concussive
syndrome (also known as mild traumatic brain injury), chronic Lyme disease, chronic diabetic neuropathy and chronic post-herpetic
neuralgia.
We believe that diagnosing fibromyalgia in Long COVID patients will increase
the potential market for TNX-102 SL as compared to market estimates from before the COVID-19 pandemic. Tonix has previously
presented its analysis of real-world evidence from the TriNetX claims database suggesting that over 40% of Long COVID patients present
with a constellation of symptoms that overlap with fibromyalgia.
According to reports by Frost
and Sullivan and Eversana that we commissioned, despite the availability of approved medications, the majority of patients fail therapy
due to either insufficient efficacy, poor tolerability, or both. Prescription pain and sleep medications are frequently prescribed off-label
for symptomatic relief, despite the lack of evidence that such medications provide a meaningful or durable therapeutic benefit, and many
of these medications carry significant safety risks and risk of dependence. For example, based on U.S. claims data, approximately 50%
of patients diagnosed with FM are prescribed opioids within 18 months of diagnosis, despite the lack of evidence for their effectiveness
and the risk of addiction and toxicity, including overdose.
10
Cocaine
Intoxication
Cocaine
is an illegal recreational drug taken for its pleasurable effects and associated euphoria. Pharmacologically, cocaine blocks the
reuptake of the neurotransmitter dopamine from central nervous system synapses, resulting in the accumulation of dopamine within
the synapse and an amplification of dopamine signaling that is related to its role in creating positive feeling. With the continued
use of cocaine, however, intense cocaine cravings occur resulting in a high potential for abuse and addiction, or dependence,
as well as the risk of cocaine intoxication. Cocaine intoxication refers to the deleterious effects on other parts of the body,
especially those involving the cardiovascular system. Common symptoms of cocaine intoxication include tachyarrhythmias and elevated
blood pressure, either of which can be life-threatening. As a result, individuals with known or suspected cocaine intoxication
are sent immediately to the emergency department, preferably by ambulance in case cardiac arrest occurs during transit. There
are approximately 505,000 emergency room visits for cocaine abuse each year in the U.S., of which 61,000 require detoxification
services. According to the National Institute on Drug Abuse, cocaine-involved deaths rose nearly 54% from 2019 to 2021, resulting
in over 24,486 deaths total.
Acute
Stress Disorder (ASD)
ASD
is a mental health condition that can occur within the first month of experiencing a traumatic event. The symptoms are similar
to those of PTSD and can affect both civilian and military populations. According to the National Center for PTSD, in the U.S.
about 60% of men and 50% of women experience at least one trauma in their lives. In the U.S. alone, one-third of emergency department
visits (40-50 million patients per year) involve evaluation after trauma exposures, and in a 2014 study involving U.S. veterans,
87% reported exposure to at least one potentially traumatic event during their service. No medications are currently available
at or near the point of care to treat patients suffering from acute traumatic events and to support long-term health.

Immunology
Organ
Transplant Rejection
Organ
transplant rejection occurs when the immune system of the organ recipient attacks the new organ as if it was an infection or tumor.
Often transplantation is the last resort for most end-stage organ failure patients, affecting either kidneys, liver, heart, lungs,
and/or pancreas. Genetic disparity between organ donor and recipient is often at the root of the rejection. Mismatched or not
closely matched organs triggers an immune reaction that leads to rejection. Overcoming this difficulty is paramount to a patient’s
survival as organ donations are in limited supply.
Gastric
and Colorectal cancers
Gastric
or stomach cancer is a disease in which malignant cancer cells line the inner lumen of the stomach. Development of this form of
cancer is often influenced by age, diet and other stomach diseases. This type of cancer begins to form in the mucosa, the surface
of the lumen that is in direct contact with the contents of the stomach, and spreads through the outer layers of the stomach as
the tumor grows.
Currently, per the National Cancer Institute, the 5-year relative survival
for stomach cancer is 36.4%. According to 2018-2021 data, approximately 0.8 percent of men and women will be diagnosed with stomach cancer
during their lifetime. In 2021, there were an estimated 130,263 people living with stomach cancer in the U.S. As of 2024, there were approximately
26,890 new cases with 10,880 deaths.
Colorectal
cancer includes cancers in the colon and the rectum, organs that are crucial to absorption of water by the body and the elimination
of food-waste. Most colorectal cancers start as a growth or polyp on the inner lining of the colon or rectum. Some types of polyps
can change into cancer over time (usually many years), but not all polyps become cancer. Adenomatous polyps are the ones that
turn malignant with time. Similar to gastric cancer, malignancy begins in the mucosal layer and spreads outwards.
The 5-year relative survival rate with colorectal cancer is 65.0%, per
the National Cancer Institute. Based on 2018-2021 data, approximately 4.0 percent of men and women will be diagnosed with colorectal cancer
during their lifetime. In 2021, there were an estimated 1,392,445 people living with colorectal cancer in the United States. As of 2024,
there were approximately 152,810 new cases with 53,010 deaths. It is the 3rd leading cause of cancer death in women, and 2nd
in men.
Infectious
Diseases
Smallpox
and Mpox
Smallpox is an acute contagious disease caused by the variola virus, or
VARV, which is a member of the orthopoxvirus family. Smallpox was declared eradicated in 1980 following a global immunization campaign.
Smallpox is transmitted from person to person by infective droplets during close contact with infected symptomatic people. Mpox is an
acute contagious disease caused by the monkeypox virus or MPXV, which is also a member of the orthopoxvirus family. Mpox symptoms are
similar to those of smallpox, although less severe. Mpox is emerging as an important zoonotic infection in humans in Central and West
Africa. Until 2022, only a few cases of mpox had been reported outside of Africa in patients who had been infected while in Africa. Starting
in May of 2022, mpox clade II cases spread rapidly in the U.S. and other countries. The Clade II mpox affects mostly men who have sex
with men in the U.S., where it has become endemic. In August 2024, the World Health Organization (“WHO”) declared mpox Clade
Ib to be a public health emergency of international concern (PHEIC) due to an outbreak in the Democratic Republic of the
Congo that spread globally, including to the United States. Clade Ib affects children as well as adults. The WHO reaffirmed the PHEIC status of mpox clade Ib in February of 2025.
Smallpox
was eradicated by a World Health Organization program that vaccinated individuals with live replicating vaccinia vaccines wherever
smallpox appeared. In the 1970s, vaccination of civilians to protect against smallpox was discontinued in the U.S.; however, smallpox
remains a material threat to national security and a proportion of military personnel, including members of the Global Response
Force continue to be vaccinated. Vaccines for smallpox and mpox are stockpiled by the U.S. government in the strategic national
stockpile and for potential widespread immunization in the event of malicious reintroduction of VARV. The U.S. National Academy
of Sciences has recently issued a consensus report raising concerns about the state of new mpox vaccines in development.

COVID-19
SARS-CoV-2 is a contagious virus causing the disease COVID-19 that became
a global pandemic in 2019 and has resulted in more than three million deaths. While the infection and mortality rates have slowed in regions
of the world with high vaccination rates, the struggle with the pathogen is ongoing and evolving since SARS-CoV-2 is mutating into new
variants. COVID-19 is characterized by fever, sore throat, acute shortness of breath, cough, and oxygen desaturation in the blood. New
variants continue to sweep across the world in successive waves. With new variants of the virus emerging, therapeutic research is addressing
the challenge of keeping up with this rapidly mutating virus. The early vaccines have been effective in limiting the severity of disease
in vaccinated individuals. Vaccines that elicit strong T cell responses are believed to have the potential to provide long-term or durable
protection.
Rare
Disease
Prader-Willi
Syndrome
PWS
is recognized as the most common genetic cause of life-threatening childhood obesity and affects males and females with equal
frequency and all races and ethnicities. The hallmarks of PWS are lack of suckling in infants and, in children and adults, severe
hyperphagia, an overriding physiological drive to eat, leading to severe obesity and other complications associated with significant
morbidity and mortality. PWS is an orphan disease that occurs in approximately one in 15,000 births. There is currently no approved
treatment for obesity and hyperphagia in adults and older children associated with PWS.

TNX-102
SL
Overview
TNX-102 SL is a proprietary sublingual tablet formulation of cyclobenzaprine
(“CBP”) that efficiently delivers CBP across the oral mucosal membrane into the systemic circulation. We have active IND’s
for TNX-102 SL as a bedtime treatment for fibromyalgia, PTSD, of multi-site pain associated with Long COVID, AAD and AUD. The University of North Carolina
has an investigator-initiated IND for ASD that references our INDs. We own all rights to TNX-102 SL in all geographies, and we bear no
obligations to third parties for any future development or commercialization. Excipients used in TNX-102 SL are approved for pharmaceutical
use. Some of the excipients were specially selected to promote a local oral environment that facilitates transmucosal absorption of CBP.
The current TNX-102 SL sublingual tablets each contain 2.8 mg of CBP. We selected this
dose with the goal of providing a balance of efficacy, safety, and tolerability that would be acceptable as a first-line therapy and for
long-term use, and in-patient populations characterized by burdensome symptoms and sensitivity to medications.
The
active ingredient in TNX-102 SL is CBP, a multi-functional drug that blocks the serotonin-2A, alpha-1 adrenergic, muscarinic M1
and histaminergic H1 receptors.
CBP
is a tertiary amine tricyclic, that is the listed active ingredient of two products that are approved in the U.S. for the treatment
of muscle spasm: Flexeril® (5 mg and 10 mg oral immediate-release, or IR, tablet) and Amrix® (15 mg and 30
mg oral extended-release capsule or ER capsule). The Flexeril brand of CBP IR tablet has been discontinued since May 2013. There
are numerous generic versions of CBP IR tablets on the market. CBP-containing products are approved for short term use (two to
three weeks) only as an adjunct to rest and physical therapy for relief of muscle spasm associated with acute, painful musculoskeletal
conditions. CBP IR tablets are recommended for three times per day dosing, which results in relatively stable blood levels of
CBP after several days of treatment. Extended-release (ER) CBP capsules taken once a day mimic, and flatten, the pharmacokinetic
profile of three times per day CBP IR tablets.
14
Both the IR and ER tablet formulations of CBP result in accumulation
of the persistent metabolite norcyclobenzaprine (“norCBP”) to blood levels that exceed the levels of CBP. NorCBP is a secondary
amine tricyclic with a relatively stronger inhibitory activity of the norepinephrine transporter (NET) than the parent CBP. We believe
that the accumulation of norCBP is undesirable in a medicine to be taken chronically at bedtime because norCBP accumulates over weeks,
potentially interfering with the dynamic receptor effects of CBP and also may interrupt sleep quality by inhibiting the NET.
We
designed TNX-102 SL to be administered once-daily at bedtime and with the intention for long-term use. We believe the selected
dose of TNX-102 SL and its unique pharmacokinetic profile will enable it to achieve a desirable balance of efficacy, safety, and
tolerability. Our Phase 1 pharmacokinetic comparative trials showed that, on a dose-adjusted basis, TNX-102 SL results in faster
systemic absorption and significantly higher plasma levels of CBP in the first hour following sublingual administration relative
to oral IR CBP tablets. It also showed that the sublingual route of administration, which bypasses the “first pass”
hepatic metabolism that swallowed medications undergo, results in a higher plasma level of CBP relative to norcyclobenzaprine
during sleeping hours when taken at bedtime. We believe the dynamic changes in CBP after TNX-102 SL administration at steady state
during chronic use contribute to its activity in treating fibromyalgia. We believe this is the first drug designed to
increase the activity of the tertiary amine tricyclic parent and decrease the activity of the secondary amine tricyclic metabolite.
In clinical studies, TNX-102 SL 2.8 mg and TNX-102 SL 5.6 mg were generally well-tolerated, with no drug-related serious and unexpected
adverse reactions reported in these studies. The most common adverse event was transient numbness in the mouth after TNX-102 SL
administration.
In
September 2024, at the 11th Global Conference on Pharmaceutics and Novel Drug Delivery Systems (PDDS 2024), the Company announced
data highlighting the proprietary formulation technology and pharmacokinetic properties of TNX-102 SL, including composition and
methods patents based on the proprietary eutectic formulation of TNX-102 SL that are expected to provide market exclusivity until
at least 2034 in the U.S., EU, Japan, China and other jurisdictions. The eutectic protects cyclobenzaprine HCl from interacting
with the basifying agent that is also part of the formulation and required for efficient transmucosal absorption. The formulation
of TNX-102 SL was designed specifically for sublingual administration and transmucosal absorption for bedtime dosing to target
disturbed sleep, improve pain and other fibromyalgia symptoms, while reducing the risk of daytime somnolence.
We have successfully completed the pivotal exposure bridging study
with TNX-102 SL compared to Amrix. Results from this study support the approval of TNX-102 SL under Section 505(b)(2) of the Federal
Food, Drug and Cosmetic Act (“FDCA”) with Amrix as the listed drug. We believe that TNX-102 SL has the potential to provide clinical
benefit in fibromyalgia and PTSD and possibly other CNS indications that are underserved by currently marketed
products or have no approved treatment.
We
have also successfully completed a bridging pharmacokinetic study in ethnic Japanese and Chinese volunteers that shows similar
characteristics to our historical data in Caucasian volunteers. We believe this will satisfy one of the criteria for approval
in Japan and China and will allow us to reference the U.S. efficacy data to support marketing applications in those countries.

Development Plan
NDA
Acceptance and PDUFA Goal Date
In October 2024, Tonix submitted its NDA to the FDA for TNX-102 SL 5.6
mg for the management of fibromyalgia and in December 2024, the FDA assigned a PDUFA goal date of August 15, 2025, for a decision on marketing
authorization for TNX-102 SL. We are preparing for a commercial launch of TNX-102 SL in the fourth quarter of 2025, conditional on FDA
approval.

Pre-NDA
Meetings and Fast Track Designation
In July 2024, Tonix was granted Fast Track designation by the FDA for TNX-102
SL for FM. The designation validates that FM is a serious condition and that TNX-102 SL has the potential to address this unmet medical
need. Tonix previously announced alignment with the FDA regarding the content of its proposed NDA submission, following completion of
the Company’s pre-NDA meetings.
During the second quarter of 2024, Tonix successfully completed two positive
pre-NDA meetings with the FDA for TNX-102 SL for the management of fibromyalgia. The first, with minutes announced in June 2024, was a
Type B Chemistry, Manufacturing, and Controls (CMC) meeting to seek alignment and agreement with the FDA on key CMC topics to support
the planned NDA submission for TNX-102 SL. Based on formal meeting minutes, the Company believes it is aligned with the FDA on proposed
drug substance and drug product commercial specifications, shelf life assignment, manufacturing and commercial drug packaging. At the
second pre-NDA meeting announced in July 2024, the Company and the FDA aligned on nonclinical, clinical pharmacology and clinical matters
and agreed that the proposed data package is sufficient to support the NDA submission.
