Topline Results Expected Third Quarter 2023

Long COVID Afflicts Approximately 19% of Patients Following COVID-19¹, and is Expected to be a Global Health Burden

Fibromyalgia-Type Long COVID with Multi-Site Pain Affects Approximately 40% of Long COVID Patients

CHATHAM, N.J., Aug. 07, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a biopharmaceutical company, today announced the completion of the clinical phase of the Phase 2 proof-of-concept PREVAIL study of TNX-102 SL as a potential treatment for fibromyalgia-type Long COVID. Topline results for the PREVAIL study are expected in the third quarter of 2023.

“Approximately 40% of U.S. Long COVID patients have fibromyalgia-like multi-site pain symptoms based on our observational studies of Long COVID patients from the TriNetX claims database,”^2,3 said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “In addition to multi-site pain, these individuals often suffer from one or more other symptoms typically associated with fibromyalgia such as fatigue, sleep disturbance, and brain fog. We have termed this subgroup, ‘Fibromyalgia-type Long COVID.’ Given our encouraging results with TNX-102 SL as a potential treatment for fibromyalgia⁴, we are testing TNX-102 SL as a bedtime medicine for the management of Fibromyalgia-type Long COVID. In completing this clinical milestone, marked by the last enrolled patient finishing their final visit, we can now begin to look forward to topline results from the 63-patient PREVAIL study later this quarter.”

Dr. Lederman continued, “TNX-102 SL improves sleep quality in fibromyalgia, and we believe this is the mechanism by which TNX-102 SL improves other symptoms, like multi-site pain.⁵ Recently, the U.S. National Institutes of Health (NIH) has identified improving sleep quality as a target for potential therapeutics for Long COVID^6,7,8, consistent with the proposed mechanism of TNX-102 SL.

“Common symptoms of Long COVID, including multi-site pain, fatigue, unrefreshing sleep, and cognitive dysfunction, or ‘brain fog,’ are also hallmarks of conditions like fibromyalgia and chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME),”⁹ said Herbert Harris, M.D., Ph.D., Executive Vice President and Head of Translational Medicine of Tonix Pharmaceuticals. “Defining subgroups of Long COVID patients that overlap with fibromyalgia and CFS/ME is expected to facilitate the development of new treatments.⁴ It can be challenging to distinguish fibromyalgia and CFS/ME clinically, given the high level of symptom overlap between them.  Each of these conditions is defined by a constellation of symptoms, and there is no widely recognized diagnostic laboratory test that distinguishes them.”

Dr. Harris continued, “The recent identification of Long COVID subgroups in the National Institutes of Allergy and Infectious Diseases (NIAID)-sponsored RECOVER study¹⁰ was an important step. In their recent publication, cluster analysis of the symptom frequencies in the RECOVER study identified four subgroups of Long COVID patients. Cluster #4 represented approximately one-quarter of the population (28%) and reported the highest frequencies of pain (back pain (58%), joint pain (64%) or muscle pain (60%)), high frequencies of fatigue (94%) and ’Brain Fog,’ (94%) and a high level of impairment of Quality of Life. We believe Cluster #4 is a subgroup of Long COVID that shares many clinical features with fibromyalgia and may involve common disease mechanisms. We also believe that Cluster #3, representing another approximately 29% of the RECOVER cohort, includes many patients with fibromyalgia-type Long COVID because 100% of that group suffer from ‘Brain Fog’, 94% experience fatigue and approximately one-third experience pain (back pain (32%), joint pain (36%) or muscle pain (34%)).”

Dr. Harris concluded, “With no FDA approved treatment for Long COVID, we understand the need to better understand long COVID and to develop treatments for subgroups of this unserved population of patients. Fibromyalgia has been recognized by the U.S. Food and Drug Administration (FDA) with three approved medicines. Consequently, measuring daily pain is a validated endpoint for FDA registrational studies in fibromyalgia. We believe that daily pain has the potential to be an endpoint for registrational studies in fibromyalgia-like long COVID.”

About the Phase 2 PREVAIL Study

The Phase 2 PREVAIL study is a 14-week double-blind, randomized, multicenter, placebo-controlled study to evaluate the efficacy and safety of TNX-102 SL taken daily at bedtime in patients with multi-site pain associated with post-acute sequelae of SARS-CoV-2 infection (PASC). The trial is being conducted at approximately 30 sites in the U.S. The primary efficacy endpoint will be the change from baseline in the weekly average of daily self-reported worst pain intensity scores at the Week 14 endpoint. Key secondary efficacy endpoints include change from baseline in self-reported scores for sleep disturbance, fatigue, and cognitive function. Topline results are expected in the third quarter of 2023.

About Long COVID or Post-Acute Sequelae of COVID-19 (PASC)

Post-acute sequelae of COVID-19, or PASC is the formal name for a condition now widely known as Long COVID. Although most people recover from COVID-19 within weeks of the acute illness, a substantial portion develops a chronic syndrome called Long COVID.¹¹ These individuals experience a constellation of disabling symptoms long past the time of recovery from acute COVID-19. Most Long COVID patients who have been studied appear to have cleared the SARS-CoV-2 infection from their systems. The symptoms of Long COVID can include fatigue, sleep disorders, multi-site pain, fevers, shortness of breath, cognitive impairment described as “brain fog” or memory disturbance, gastrointestinal symptoms, anxiety, and depression. According to the Centers for Disease Control and Prevention (CDC), 1 in 13 adults in the U.S. (7.5%) have Long COVID symptoms.¹ Long COVID is typically associated with moderate or severe COVID-19, but can occur after mild COVID-19 or even after asymptomatic SARS-CoV-2 infection. More than 40% of adults in the United States reported having COVID-19 in the past, and nearly one in five of those (19%) are currently still having symptoms of Long COVID.¹ Long COVID is a chronic disabling condition that is expected to result in a significant global health and economic burden.^12-15 In response to the urgent need for therapies that address Long COVID, Congress awarded $1.15 billion to the National Institutes of Health to study Long COVID in December 2020¹⁶ The U.S. Department of Health and Human Services National Research Action Plan on Long COVID¹⁷, released in August 2022, addresses the overlap of Long COVID with CFS/ME, which, like fibromyalgia, is one of the overlapping chronic pain syndromes with central and peripheral sensitization.¹⁸ A published survey¹⁹ found comparable pain, fatigue, and functional impairment between Long COVID, fibromyalgia, and CFS/ME. This symptom overlap between these conditions has suggested that altered neurologic function is one of the leading hypotheses to explain them.²⁰ While the vaccines available in the U.S., through either FDA approval or under Emergency Use Authorization, have been shown to prevent acute COVID, their ability to prevent Long COVID is unknown. There is currently no approved drug for the treatment of Long COVID. Fibromyalgia-type Long COVID, like fibromyalgia and CFS/ME, appears to be one of several chronic overlapping pain conditions that have in common the neurological process called central and peripheral sensitization, which is increasingly known by the term nociplastic pain.

Topline Data Expected Fourth Quarter 2023

Final Trial Required for Submission of a New Drug Application, if Successful

CHATHAM, N.J., Aug. 01, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a biopharmaceutical company, today announced that it has completed enrollment of its potentially final, confirmatory Phase 3 RESILIENT trial of TNX-102 SL (cyclobenzaprine HCL sublingual tablets) 5.6 mg in fibromyalgia and expects topline data next quarter. A total of 457 participants were randomized. TNX-102 SL is in development as a non-opioid, centrally acting analgesic, to be taken daily at bedtime for the management of fibromyalgia. If successful, we believe this will be the final, well-controlled efficacy trial required for submission of a New Drug Application (NDA) for approval by the U.S. Food and Drug Administration (FDA).

“The completion of enrollment in our Phase 3 RESILIENT trial is a significant milestone for both Tonix and the fibromyalgia community,” said Seth Lederman, M.D., Chief Executive Officer of Tonix. “Currently-approved treatments have not fully met the needs of fibromyalgia patients and there has not been a new FDA-approved therapy for the condition since 2009. TNX-102 SL has the potential to be a new non-addictive, non-opioid bedtime medication with broad spectrum symptom coverage and which can be used on a chronic basis for the management of fibromyalgia. With all other clinical, nonclinical and CMC requirements for an NDA submission achieved, we are looking forward to the upcoming data readout and an expeditious filing of an NDA.”

In December 2020, Tonix reported positive results from the first Phase 3 study (RELIEF) of TNX-102 SL 5.6 mg for the management of fibromyalgia. TNX-102 SL met its pre-specified primary endpoint in the Phase 3 RELIEF trial, significantly reducing daily pain compared to placebo (p=0.01) in participants with fibromyalgia. Also, when the primary endpoint was analyzed as a ≥30% pain responder analysis, there was a higher rate of responders to TNX-102 SL (47%) than to placebo (35%; p=0.006). TNX-102 SL at 5.6 mg also showed activity in key secondary endpoints demonstrating improvements in sleep quality, mitigation of fatigue, and fibromyalgia-specific global symptomatic and functional recovery. TNX-102 SL was generally safe and well tolerated in patients with fibromyalgia, with overall adverse event profile comparable to prior fibromyalgia studies. The most common treatment-emergent adverse events were oral hypoesthesia, oral paresthesia, and product taste abnormal.

About the Phase 3 RESILIENT Study

The RESILIENT study is a double-blind, randomized, placebo-controlled trial designed to evaluate the efficacy and safety of TNX-102 SL (cyclobenzaprine HCl sublingual tablets) in the management of fibromyalgia. The two-arm trial randomized 457 participants in the U.S. The first two weeks of treatment consist of a run-in period in which participants start on TNX-102 SL 2.8 mg (1 tablet) or placebo. Thereafter, all participants increase their dose to TNX-102 SL 5.6 mg (2 x 2.8 mg tablets) or two placebo tablets for the remaining 12 weeks. The primary endpoint is the daily diary pain severity score change (TNX-102 SL 5.6 mg vs. placebo) from baseline to Week 14 (using the weekly averages of the daily numerical rating scale scores), analyzed by mixed model repeated measures with multiple imputation.

About Fibromyalgia

Fibromyalgia is a chronic pain disorder that is understood to result from amplified sensory and pain signaling within the central nervous system. Fibromyalgia afflicts an estimated 6-12 million adults in the U.S., approximately 90% of whom are women. Symptoms of fibromyalgia include chronic widespread pain, nonrestorative sleep, fatigue, and morning stiffness. Other associated symptoms include cognitive dysfunction and mood disturbances, including anxiety and depression. Individuals suffering from fibromyalgia struggle with their daily activities, have impaired quality of life, and frequently are disabled. Physicians and patients report common dissatisfaction with currently marketed products.

About TNX-102 SL

TNX-102 SL is a patented sublingual tablet formulation of cyclobenzaprine hydrochloride which provides rapid transmucosal absorption and reduced production of a long half-life active metabolite, norcyclobenzaprine, due to bypass of first-pass hepatic metabolism.

The United States Patent and Trademark Office (USPTO) issued United States Patent No. 9636408 in May 2017, Patent No. 9956188 in May 2018, Patent No. 10117936 in November 2018, Patent No. 10,357,465 in July 2019, and Patent No. 10736859 in August 2020. The Protectic™ protective eutectic and Angstro-Technology™ formulation claimed in the patent are important elements of Tonix’s proprietary TNX-102 SL composition. These patents are expected to provide TNX-102 SL, upon NDA approval, with U.S. market exclusivity until 2034/2035.

Research News and Market Data on TNXP

Preliminary Data Show that Oxytocin Decreases Impulsivity and Reduces Food Intake

TNX-1900 (Intranasal Potentiated Oxytocin) May Serve as a Novel Neuroendocrine Treatment for Binge-Eating Disorder

CHATHAM, N.J., July 31, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced that the first participant was enrolled in the investigator-initiated Phase 2 Study of The Results of Oxytocin in Binge Eating ‘STROBE’ study of TNX-1900 (intranasal potentiated oxytocin) for the treatment of binge-eating disorder at the Massachusetts General Hospital (MGH). The aim of the study is to investigate the efficacy and safety of TNX-1900 as a novel therapeutic agent to reduce binge eating frequency in adults with binge-eating disorder. Tonix is supporting the STROBE study through a clinical trial agreement with MGH. MGH is the sponsor of the trial, which is being conducted under an investigator-initiated investigational new drug (IND) application.

The 8-week double-blind, placebo-controlled trial has a target enrollment of at least 60 participants 18-45 years old with binge-eating disorder.

“Binge-eating disorder is identified as a reduced ability to control behavioral impulses and formed habits, disrupting the regulation of food intake and energy balance,”^1-4 said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “While existing treatment options may produce remission from binge eating in some cases, up to 50% of patients continue to engage in binge eating.”^5-7

Elizabeth A. Lawson, M.D., M.M.Sc., Director, Interdisciplinary Oxytocin Research Program in the Neuroendocrine Unit, Department of Medicine, Massachusetts General Hospital and principal investigator of the study added, “Individuals with binge-eating disorder experience loss of control over eating that is thought to be driven by increased hedonic drive to eat as well as impulsivity.^8-10 The oxytocin system has been linked to likelihood of lifetime binge eating in women¹¹, and our preliminary studies of intranasal oxytocin at the dose used in this trial show that oxytocin modulates areas of the brain responsible for hedonic eating and impulse control¹², improves impulsivity¹³, and reduces caloric intake.¹⁴ The goal of the STROBE study is to assess whether 8 weeks intranasal administration of oxytocin will decrease binge eating frequency by lowering the drive to eat and improving impulse control.”

About the Phase 2 STROBE Study

The Phase 2 STROBE study is a randomized, double blind, placebo-controlled study to evaluate the efficacy and safety of TNX-1900 for the treatment of binge-eating disorder in adults. The 8-week trial has a target enrollment of at least 60 participants 18-45 years old with binge-eating disorder. Subjects will be randomized to receive TNX-1900 or placebo and will be studied at Massachusetts General Hospital. Subjects will self-administer TNX-1900 or placebo as two sprays total (one spray in each nostril) up to four times per day for 8 weeks. The primary endpoint is 8-week change from baseline in binge frequency.

About Binge Eating Disorder

Binge-eating disorder (BED) is a psychiatric illness characterized by frequent episodes of uncontrollable consumption of large amounts of food. It is the most common eating disorder and often leads to obesity-associated complications and later psychopathology¹⁵. BED is characterized by increased homeostatic appetite and sensitivity to reward (including food reward)¹⁶, which may lead to initiation of binge episodes, and a reduced ability to control behavioral impulses and formed habits, creating an imbalance in the sensitive interplay between these bottom-up and top-down processes governing the adaptive regulation of food intake and energy balance^1-4.

About TNX-1900

TNX-1900 (intranasal potentiated oxytocin) is a proprietary formulation of oxytocin in development as a candidate for prevention of chronic migraine and other conditions. In 2020, TNX-1900 was acquired from Trigemina, Inc. who had licensed the technology underlying the composition and method from Stanford University. TNX-1900 is a drug-device combination product, based on an intranasal actuator device that delivers oxytocin into the nasal cavity. Oxytocin is a naturally occurring human peptide hormone that also acts as a neurotransmitter in the brain. Oxytocin has no recognized addiction potential. It has been observed that low oxytocin levels in the body are associated with increases in migraine headache frequency, and that increased oxytocin levels are associated with fewer migraine headaches. Certain other chronic pain conditions are also associated with decreased oxytocin levels. Migraine attacks are caused, in part, by the activity of pain-sensing trigeminal neurons which, when activated, release of calcitonin gene-related peptide (CGRP) which binds to receptors on other nerve cells and starts a cascade of events that is believed to result in headache. Oxytocin when delivered via the nasal route, concentrates in the trigeminal system¹⁷ resulting in binding of oxytocin to receptors on neurons in the trigeminal system, inhibiting the release of CGRP and transmission of pain signals returning from the site of CGRP release.¹⁸ Blocking CGRP release is a distinct mechanism compared with CGRP antagonist and anti-CGRP antibody drugs, which block the binding of CGRP to its receptor. With TNX-1900, the addition of magnesium to the oxytocin formulation enhances oxytocin receptor binding¹⁹ as well as its inhibitory effects on trigeminal neurons and resultant craniofacial analgesic effects, as demonstrated in animal models²⁰. Intranasal oxytocin has been shown to be well tolerated in several clinical trials in both adults and children²¹. Targeted nasal delivery results in low systemic exposure and lower risk of non-nervous system, off-target effects, which could potentially occur with systemic CGRP antagonists such as anti-CGRP antibodies²². For example, CGRP has roles in dilating blood vessels in response to ischemia, including in the heart. The Company believes nasally targeted delivery of oxytocin could translate into selective blockade of CGRP release from neurons in the trigeminal ganglion and not throughout the body, which could be a potential safety advantage over systemic CGRP inhibition. In addition, daily dosing is more rapidly reversible, in contrast to monthly or quarterly dosing, as is the case with anti-CGRP antibodies, giving physicians and their patients greater control. In addition to chronic migraine, TNX-1900 will be developed for treatment of episodic migraine, binge eating disorder, craniofacial pain conditions, and insulin resistance. Tonix also has a license with the University of Geneva to use TNX-1900 for the treatment of insulin resistance and related conditions.

About TNX-2900

TNX-2900 is another intranasal potentiated oxytocin-based therapeutic candidate, being developed for the treatment of Prader-Willi syndrome, or PWS. The technology for TNX-2900 was licensed from the French National Institute of Health and Medical Research. PWS, an orphan condition, is a rare genetic disorder of failure to thrive in infancy, associated with uncontrolled appetite later in childhood.

Reallocating Resources to Development of Single Isomer TNX-4300 (Estianeptine)

Estianeptine in Preclinical Development Has Demonstrated Key Activities Related to in vivo Novel Object Recognition and in vitro Neuroplasticity, Without the µ-Opioid Receptor Activity of Racemic and (R)-Tianeptine

New Findings Support Development of TNX-4300 as a First-in-Class Oral Therapy in Depression, Alzheimer’s Disease and Other Psychiatric and Neurodegenerative Conditions with Memory Deficits

CHATHAM, N.J., July 26, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a biopharmaceutical company, today announced that development of TNX-4300* (estianeptine), the single (S)-isomer of tianeptine will be prioritized over TNX-601 ER*, which is being studied in the Phase 2 UPLIFT¹ trial for the treatment of major depressive disorder (MDD). TNX-4300 is in preclinical development for mood disorders, Alzheimer’s disease and Parkinson’s disease. Recent findings have shown estianeptine possesses the ability to improve memory and cognition in vivo as measured in the rat Novel Object Recognition (NOR) test, and the ability to restore neuroplasticity to neurons in cell culture. The finding that estianeptine is responsible for improving memory and cognition in vivo suggests a role for peroxisome proliferator-activated receptor PPAR-β/δ activation in memory. For these reasons, Tonix intends to accelerate completion of enrollment for the Phase 2 UPLIFT¹ trial to reallocate resources to the preclinical development of TNX-4300 and now expects to report topline data from this study in the fourth quarter of 2023. Tonix is also accelerating completion of enrollment in the RESILIENT study of TNX-102 SL for the management of fibromyalgia so that approximately 450 patients will be enrolled, and topline results are expected in the fourth quarter of 2023.

Racemic tianeptine is an antidepressant that has been marketed outside the U.S. for more than 30 years. Tianeptine is also a racemic drug composed of a 1:1 mixture of two mirror-image isomers. Tonix recently reported that the (S)-isomer (estianeptine) is responsible for its positive effects on neuroplasticity in cell culture, while the (R)-isomer is responsible for racemic tianeptine’s off-target activity on the µ-opioid receptor.^2,3 Tonix also recently reported that estianeptine activates PPAR-β/δ. These activities on molecular targets in neurons and glia in the brain are believed to relate to tianeptine’s ability to restore connectivity between neurons that atrophy in conditions of stress or depression in animal models.⁴ Tianeptine’s mechanism is distinct from traditional antidepressants that alter the level or activity of serotonin, norepinephrine, and dopamine neurotransmitters, which are believed to indirectly induce neurons to make new connections.⁵

“The memory- and cognition-enhancing effects of racemic tianeptine and estianeptine seen in the NOR test are consistent with human clinical studies in which racemic tianeptine treatment improved cognition and memory in patients with Alzheimer’s disease and depression⁶ and in patients with bipolar disorder,⁷” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “We also recently reported that estianeptine induces neuroplasticity in cell culture.² Together these findings support the development of estianeptine in psychiatric and neurodegenerative diseases.”

“Given the time and expense of developing new drugs, the scientific and clinical advantages of TNX-4300 lead us to focus our efforts on this preclinical program as a potential treatment for mood disorders like depression and neurodegenerative conditions like Alzheimer’s disease,” said Gregory Sullivan, M.D., Chief Medical Officer of Tonix Pharmaceuticals. “The finding that TNX-4300 possesses the desirable attributes of racemic tianeptine and at the same time lacks a measurable opioid liability supports the focus of our resources on this candidate. Multiple studies around the world have already shown that racemic tianeptine is effective in treating depression. However, our in vivo animal studies and in vitro lab studies have indicated that TNX-4300 is potentially a more active and safer drug.”

Dr. Sullivan continued, “TNX-601 ER, which contains racemic tianeptine, has informed the future development of TNX-4300 which contains the single isomer, estianeptine. We believe that estianeptine bypasses the synapse and activates intracellular PPAR-β/δ and PPAR-γ targets. The finding that estianeptine is responsible for tianeptine’s ability to improve memory and cognition in the NOR test implicates PPAR-β/δ activation specifically as a molecular target. This finding is consistent with the impaired memory of mice lacking the PPAR-β/δ gene.”⁸

Tonix has filed patents claiming single (S)-isomer estianeptine, the active ingredient in TNX-4300, which is devoid of activity on the µ-opioid receptor in tissue culture. Tonix has filed patent claims that describe crystalline salt forms of estianeptine that appear well suited to formulation. TNX-4300 is currently in preclinical development for depression, bipolar disorder, Alzheimer’s disease, and Parkinson’s disease. Key experiments were performed by scientists at Tonix’s Research and Development Center (RDC) in Frederick, Maryland.

^*TNX-601 ER and TNX-4300 are investigational new drugs and are not approved for any indication. TNX-601 ER is being developed under an IND. TNX-4300 is at the pre-IND stage of development.

About Tianeptine

Racemic tianeptine sodium (amorphous) immediate release (dosed 3 times daily) was first marketed for depression in France in 1989 and has been available for decades in Europe, Russia, Asia, and Latin America for the treatment of depression. Tianeptine sodium has an established tolerability profile from decades of use in these jurisdictions. Currently no tianeptine-containing product is approved in the U.S. and no extended-release once-daily tianeptine product is approved in any jurisdiction. In animal models, tianeptine restores dendritic arborization of pyramidal neurons in the CA3 region of hippocampus and in the dentate gyrus region promotes new neuron formation and integration into hippocampal networks.⁴ Tianeptine’s enhancement of neuroplasticity in animal models of stress is believed to be mediated by activation of PPAR isoforms PPAR-β/δ and PPAR-γ, which is mechanistically distinct from traditional monoaminergic antidepressants marketed in the U.S. and contributes to its potential for clinical indications beyond depression and stress disorders. Tianeptine and its MC5 metabolite are also weak µ-opioid receptor (MOR) agonists that present a potential abuse liability if illicitly misused in large quantities.^3,9 In cases where tianeptine has been abused, the dose has been approximately 8-80 times the therapeutic dose in depression on a daily basis.⁹ In patients who were prescribed tianeptine for depression, the French Transparency Committee found an incidence of misuse of approximately 1 case per 1,000 patients treated¹⁰ suggesting low abuse liability when used at the antidepressant dose in patients prescribed tianeptine for depression. Clinical trials have shown that cessation of a therapeutic course of tianeptine does not appear to result in dependence or withdrawal symptoms following 6-weeks^11-15, 3-months,¹⁶ or 12-months¹⁷ of treatment. Estianeptine is believed to mimic naturally occurring polyunsaturated fatty acid ligands in low affinity interactions with PPAR-β/δ and PPAR-γ. Estianeptine’s activation of nuclear PPAR-β/δ and PPAR-γ receptors appears to be a more direct mechanism to achieve the goal of restoring neuronal connectivity than the active ingredients of current pharmacologic therapies for depression. Tianeptine’s proposed mechanism as a plastogen is consistent with its clinical effects in promoting cognition in depressed patients with Alzheimer’s disease⁵ and in patients with bipolar disorder.⁶ The PPAR-β/δ target is validated by prior work on agonists treating animal models of neurodegenerative and autoimmune diseases of the central nervous system.¹⁸ Alzheimer’s disease has been proposed to be a form of diabetes that affects the CNS, sometimes termed type-III diabetes.”¹⁹ The PPAR superfamily plays key roles in metabolic processes, and activation of PPAR-β/δ in brain by tianeptine shows promise to prevent the cognitive dysfunction associated with CNS insulin resistance. Tianeptine’s reported pro-cognitive and anxiolytic effects as well as its ability to attenuate the neuropathological effects of excessive stress responses suggest other potential uses including as a treatment for posttraumatic stress disorder (PTSD), as well as for preventing neurocognitive dysfunction associated with corticosteroid use.
