Risks

• Failure to obtain FDA clearances or approvals for product candidates, including TNX-102 SL.
• Noncompliance with FDA regulations.
• Failure to successfully market any approved products.
• Risks related to the timing and progress of clinical development of product candidates.
• Need for additional financing to support operations and development.
• Uncertainties regarding patent protection and potential litigation.
• Uncertainties of government or third-party payor reimbursement for products.
• Limited research and development efforts and dependence upon third parties for certain aspects of development.
• Substantial competition from other pharmaceutical companies.
• Actual results may differ materially from forward-looking statements due to various factors.

Future Outlook

The company anticipates a PDUFA goal date of August 15, 2025, for TNX-102 SL, with a potential US commercial launch in Q4 2025, supported by a planned sales force of 70-90 representatives. It expects TNX-102 SL to be the first FDA-approved fibromyalgia therapy in over 15 years, offering durable pain reduction, improved sleep, and reduced fatigue with a favorable tolerability profile. Future plans include initiating a Phase 2 study for TNX-1500 in kidney transplant recipients, expecting topline results for TNX-102 SL in Acute Stress Disorder in the second half of 2026, and advancing TNX-1700 to IND. The TNX-4200 program is expected to support an IND submission and fund a first-in-human Phase 1 clinical study.

Management Comments

• Committed to improving health by inventing, developing and delivering impactful solutions, through robust in-house capabilities and creative collaborations, to address important unmet needs in nociplastic pain, immunology / immuno-oncology, and infectious disease.
• Empowering Patients Through Possibility.
• We believe the results of this study and our prior animal studies indicate that TNX-1500 is potentially best-in-class among anti-CD40L mAbs in development.

Industry Context

The fibromyalgia market is large and underserved, with over 10 million U.S. adults affected and 2.7 million diagnosed and treated annually, yet patients express high dissatisfaction with existing therapies, leading to significant off-label use and high churn. There have been no new FDA-approved fibromyalgia therapies in over 15 years. The acute migraine market continues to view sumatriptan as a gold standard. In immunology, the CD40-CD40L pathway is a critical immune modulator and a promising therapeutic target, while in infectious diseases, there is a growing trend towards broad-spectrum antivirals, moving away from the "one drug, one bug" approach.

Comparison to Industry Standards

• Fibromyalgia (TNX-102 SL): Aims to be the first FDA-approved therapy in over 15 years, addressing a market where 85% of patients fail first-line therapy and 79% are on multiple drugs. Unlike current FDA-approved drugs (Pregabalin/Lyrica, Duloxetine/Cymbalta, Milnacipran/Savella) which have significant tolerability issues (e.g., weight gain, blood pressure increase, sexual impairment) and do not comprehensively address pain, sleep, and fatigue, TNX-102 SL demonstrated durable pain reduction, improved sleep, and less fatigue with a generally well-tolerated profile.
• Anti-CD40L Antibodies (TNX-1500): Positioned as a third-generation anti-CD40L antibody, TNX-1500 is engineered to overcome the thromboembolic complications that halted first-generation development (e.g., Ruplizumab) and the reduced potency/half-life of second-generation antibodies. Phase 1 results support its potency and favorable safety, leading management to believe it is "potentially best-in-class" among current anti-CD40L mAbs in development.
• Immuno-oncology (TNX-1700): Preclinical data suggests TNX-1700 can augment the efficacy of anti-PD-1 therapy, particularly for "cold tumors," a challenge where no existing product has consistently shown such an effect.
• Antivirals (TNX-4200): The development of TNX-4200 as a broad-spectrum, host-directed antiviral represents a strategic shift from the traditional "one drug, one bug" approach, aiming to protect against multiple viral infections, a differentiator in the antiviral landscape.

Legal Proceedings

• The European Patent Office's Opposition Division maintained Tonix's European Patent EP 2 968 992 in unamended form after an opposition was filed by a Sandoz subsidiary, Hexal AG, which did not appeal the decision.

Stakeholder Impact

• Shareholders/Investors: Potential for increased share value due to anticipated FDA approval and commercial launch of TNX-102 SL, and advancement of a diverse pipeline.
• Patients: Fibromyalgia patients may gain access to a new, potentially more effective and tolerable treatment option (TNX-102 SL) that addresses multiple symptoms.
• Healthcare Professionals: Will have a new FDA-approved option for fibromyalgia management, potentially simplifying treatment decisions and improving patient outcomes.
• Employees: Opportunities for growth and expansion, particularly with the planned hiring of a new sales force.
• Creditors/Suppliers: Increased business activity and potential revenue could strengthen financial standing.

Next Steps

• FDA PDUFA goal date for TNX-102 SL on August 15, 2025.
• Potential US commercial launch of TNX-102 SL in Q4 2025.
• Initiate Phase 2 study for TNX-1500 in Kidney Transplant Recipients.
• Expect topline results for TNX-102 SL in Acute Stress Disorder in the second half of 2026.
• Progress TNX-1700 to IND (Investigational New Drug) stage.
• Establish physicochemical properties, pharmacokinetics, and safety attributes for TNX-4200 to support an IND submission and fund a first-in-human Phase 1 clinical study.
• Implement an omni-channel marketing and messaging campaign for TNX-102 SL.
• Deploy a sales force of 70-90 representatives for TNX-102 SL upon approval.
