Expanded Pipeline in 2019 with Three In-licensed Programs
First Quarter 2020 Stock Offerings Raised $29.0 Million in Net Proceeds to Support Pipeline Advancement
NEW YORK, March 24, 2020 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals Holding Corp. (TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced financial results for the quarter and year ended December 31, 2019, and provided an overview of recent operational highlights.
“Our focus in 2020 will be on further advancement of our vaccine and pain programs: TNX-1800 as a potential vaccine to protect against COVID-19, TNX-801 as a potential vaccine against smallpox and monkeypox, and TNX-102 SL for the management of fibromyalgia. We expect results of the interim analysis for the Phase 3 RELIEF study for TNX-102 SL for the treatment of fibromyalgia in the third quarter of this year, however interruptions due to the COVID-19 pandemic may alter those timelines,” said Seth Lederman, M.D., President and Chief Executive Officer. “In addition to these programs, we maintain a strong and growing pipeline of product candidates including TNX-102 SL as a treatment for agitation in Alzheimer’s disease and alcohol use disorder, TNX-601 CR as a treatment for major depressive disorder, treatment for PTSD and treatment for corticosteroid-induced cognitive dysfunction, TNX-1300 for the treatment of cocaine intoxication, TNX-1500 for the prevention and treatment of organ transplant rejection, and TNX-1200 as a vaccine against smallpox and monkeypox disease. Furthermore, we look forward to advancing our pipeline of other product candidates.”
Research and Development
TNX-1800 (live recombinant horsepox virus (rHPXV/SARS-CoV2-S3) vaccine from cell culture)
In first quarter 2020, Tonix announced a strategic collaboration with the Southern Research Institute to support development of TNX-1800, a potential vaccine to protect against COVID-19. TNX-1800 is based on Tonix’s proprietary horsepox vaccine platform, which the Company believes can be engineered to express relevant protein antigens from different infectious diseases to make a variety of vaccines. The collaboration with Southern Research will develop and test TNX-1800, which is designed to express the Spike protein from the SARS-CoV-2 virus that causes COVID-19. Tonix plans to test whether vaccination of animals with TNX-1800 will elicit an immune response to the SARS-CoV-2 Spike protein and if so, whether such an immune response will protect animals against COVID-19-like disease. TNX-1800 is in the pre-clinical, pre-Investigational New Drug (IND) application stage of development. The company expects preliminary data from animal experiments in the third quarter of 2020, but the COVID-19 pandemic may lead to a delay in this timeline.
TNX-801 (live synthesized horsepox virus (sHPXV) vaccine from cell culture)
Tonix is developing TNX-801 as a preventative vaccine for active immunization against smallpox and monkeypox diseases for individuals at high risk for infection. In the first quarter of 2020, the Company presented data at the American Society of Microbiology Biothreats meeting that showed that TNX-801 protected macaques from challenge with monkeypox virus.
TNX-102 SL (cyclobenzaprine HCl sublingual tablets)
During the fourth quarter of 2019, the Company initiated the Phase 3 RELIEF study, a potential pivotal study of TNX-102 SL* (cyclobenzaprine HCl sublingual tablets) 5.6 mg, a non-opioid, centrally acting analgesic, taken daily at bedtime for the management of fibromyalgia. RELIEF is a double-blind, randomized, placebo-controlled adaptive design trial designed to evaluate the efficacy and safety of TNX-102 SL in fibromyalgia. Interim analysis results are expected in the third quarter of 2020, with topline results expected in the first half of 2021 based on the currently-planned sample size. The COVID-19 pandemic may lead to a delay in recruitment for RELIEF which could delay the interim analysis and topline results, but to date the trial is on schedule.
Supported by the previous safety and efficacy findings of TNX-102 SL in fibromyalgia at 2.8 mg and posttraumatic stress disorder (PTSD) at 5.6 mg, Tonix believes that using the 5.6 mg dose of TNX-102 SL in the Phase 3 RELIEF fibromyalgia study has the potential to provide clinical evidence to support the efficacy and safety of TNX-102 SL for the management of fibromyalgia. The registration of TNX-102 SL 5.6 mg for the fibromyalgia indication is expected to be supported by the long-term safety exposure data from the PTSD program for TNX-102 SL 5.6 mg.
In February 2020, the Company announced it stopped enrollment in the Phase 3 RECOVERY study of TNX-102 SL* (cyclobenzaprine HCl sublingual tablets) 5.6 mg for the treatment of PTSD following an unblinded, pre-specified interim analysis by the Independent Data Monitoring Committee (IDMC). Based on interim analysis results of the first 50% of enrolled participants, the IDMC recommended stopping the trial for futility as TNX-102 SL is unlikely to demonstrate a statistically significant improvement in the primary endpoint of overall change from baseline in the severity of PTSD symptoms, as measured by the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) between those treated with TNX-102 SL and those receiving placebo. Preliminary blinded safety data from these participants did not reveal any serious and/or unexpected adverse events and the decision to discontinue enrollment in the study is not related to safety. The Company intends to continue studying those participants currently enrolled until completion and then proceed with a full analysis of the unblinded data to determine the next steps in this program, with the topline results expected to be reported in the second quarter of 2020.
TNX-102 SL is in development for the treatment of agitation in Alzheimer’s disease (AAD), which has been designated as a Fast Track development program by the Food and Drug Administration (FDA). The program is ready for a Phase 2 study which could potentially serve as a pivotal efficacy study to support a New Drug Application (NDA) approval.
TNX-102 SL is in development as a treatment for alcohol use disorder (AUD), with an IND application to be submitted in the first half of 2020. The AUD program is expected to be ready for a Phase 2 proof-of-concept study upon FDA clearance of the IND application. AUD is a chronic relapsing brain disease characterized by compulsive alcohol use, loss of control over alcohol intake, and a negative emotional state when not using.
TNX-601 CR (tianeptine oxalate controlled-release)
The Company announced in the fourth quarter of 2019 the successful completion of a Phase 1 study evaluating the safety, tolerability and pharmacokinetics (PK) of controlled release (CR) formulations of TNX-601 (tianeptine oxalate). TNX-601 CR is being developed as a once-daily treatment for major depressive disorder (depression) in addition to PTSD and corticosteroid-induced cognitive dysfunction. Tonix plans to start the first efficacy trial ex-U.S. in 2021 and request a pre-IND meeting with the FDA in 2020.
TNX-1300 (double mutant cocaine esterase)
TNX-1300 is a recombinant protein under development as a treatment for a life-threatening degree of cocaine intoxication. TNX-1300 was granted Breakthrough Therapy designation by the FDA. Tonix in-licensed TNX-1300 in May 2019 from Columbia University, after a Phase 2 study on volunteers showed that TNX-1300 disintegrates cocaine in the blood stream after i.v. cocaine challenge. In 2019, the Company met with FDA to discuss and reach agreement on the design of toxicology studies for TNX-1300 to support a Phase 2 clinical study. The company has recertified TNX-1300 drug product for use in future clinical trials.
TNX-1500 (monoclonal antibody anti-CD154)
The Company entered into a research collaboration with Massachusetts General Hospital to develop TNX-1500, Tonix’s internally developed, proprietary anti-CD154 (or CD40-ligand) monoclonal antibody that targets CD154 for the prevention and treatment of organ transplant rejection. TNX-1500 is also a potential treatment for autoimmune conditions.
Other Pipeline Programs
TNX-1600 (triple reuptake inhibitor): Obtained an exclusive license for a triple reuptake inhibitor, TNX-1600, to treat PTSD and potentially other central nervous system disorders. The transaction was a license agreement with Wayne State University and an asset acquisition from TRImaran Pharma, Inc.
TNX-1700 (recombinant trefoil factor 2, or rTFF2): Obtained an exclusive license from Columbia University for the development of a biologic, TNX-1700 (recombinant trefoil factor 2, or rTFF2), for the treatment of gastric and pancreatic cancers. The in-licensed technology was invented and developed, in part, by Dr. Timothy C. Wang, Chief, Division of Digestive and Liver Diseases, and Director of the Gastrointestinal and Pancreas Cancer Program and Tumor Biology and Microenvironment program in the Herbert Irving Cancer Center at Columbia University.
Fourth Quarter 2019 Financial Results
Research and development expenses for the fourth quarter of 2019 totaled $5.7 million, compared to $5.1 million for the same period in 2018. This increase is primarily due to increased work related to TNX-601 CR, including the PK study, and an increase in non-clinical expenses related to pipeline development.
General and administrative expenses for the fourth quarter of 2019 totaled $3.0 million, compared to $2.6 million for the same period in 2018. The modest increase is primarily due to an increase in patent prosecution and maintenance costs.
Net loss available to common stockholders was $11.2 million, or $2.86 per share, for the fourth quarter of 2019, compared to net loss of $10.9 million, or $59.85 per share, for the fourth quarter of 2018. The weighted average common shares outstanding, basic and diluted, were 3,912,800 for the fourth quarter of 2019 and 181,344 for the fourth quarter of 2018, which amounts have been retroactively restated to reflect a 1-for-10 reverse stock split of our issued and outstanding shares that was effectuated on November 1, 2019.
Full Year 2019 Financial Results
Research and development expenses for full year 2019 totaled $18.2 million, compared to $17.6 million for the same period in 2018. This increase is primarily due to the ramp-up of work related to TNX-601 and an increase in expenses related to pipeline development.
General and administrative expenses for full year 2019 totaled $10.6 million, compared to $8.8 million for the same period in 2018. The increase is primarily due to higher insurance premiums and an increase in legal fees.
Net loss available to common stockholders was $31.1 million, or $19.33 per share, for full year 2019, compared to net loss of $29.4 million, or $259.85 per share, for full year 2018. The weighted average common shares outstanding, basic and diluted, for 2019 was 1,608,568 shares. The weighted average common shares outstanding, basic and diluted, for 2018 was 112,968 shares.
At December 31, 2019, Tonix had $11.2 million of cash and cash equivalents, compared to $25.0 million as of December 31, 2018. In the first quarter of 2020, the Company raised net proceeds of approximately $29.0 million through equity financings and warrant exercises. Following the offerings, the Company had an aggregate of 49,353,134 shares of common stock outstanding. Cash used in operations was $26.7 million for the full year 2019, compared to $24.0 million for the full year 2018.
About TNX-801* and TNX-1800*
TNX-1800 is a modified horsepox virus that is designed to express the Spike protein of the SARS-CoV-2 virus that causes COVID-19. TNX-801 is a live virus vaccine based on synthesized horsepox1. Horsepox and vaccinia are closely related orthopoxviruses that are believed to share a common ancestor. Live replicating orthopoxviruses, like vaccinia or horsepox, can be engineered to express foreign genes and have been explored as platforms for vaccine development because they possess; (1) large packaging capacity for exogenous DNA inserts, (2) precise virus-specific control of exogenous gene insert expression, (3) lack of persistence or genomic integration in the host, (4) strong immunogenicity as a vaccine, (5) ability to rapidly generate vector/insert constructs, (6) readily manufacturable at scale, and (7) ability to provide direct antigen presentation. Relative to vaccinia, horsepox has substantially decreased virulence in mice1. TNX-801 vaccinated macaques showed no overt clinical signs after monkeypox challenge2.

About the Phase 3 RELIEF Study
The RELIEF study is a double-blind, randomized, placebo-controlled adaptive design trial designed to evaluate the efficacy and safety of TNX-102 SL (cyclobenzaprine HCl sublingual tablets) in fibromyalgia. The trial is expected to enroll approximately 470 patients across approximately 40 U.S. sites. For the first two weeks of treatment, there will be a run-in period in which patients will start on TNX-102 SL 2.8 mg (1 tablet) or placebo. After the first two weeks, all patients will have the dose increased to TNX-102 SL 5.6 mg (2 x 2.8 mg tablets) or two placebo tablets for 12 weeks. The primary endpoint is daily diary pain severity score change 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.
The RELIEF study is expected to have one unblinded interim analysis when the study has results from approximately the first 50% of efficacy-evaluable patients, pending agreement with the FDA. Additional details about the RELIEF study are available at www.theRELIEFstudy.com or clinicaltrials.gov (NCT04172831).
