BERKELEY HEIGHTS, N.J., Aug. 10, 2026 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (“Tonix” or the “Company”), a fully integrated, commercial-stage biopharmaceutical company, today announced financial results for the quarter ended June 30, 2026, and provided an overview of recent operational highlights.

“We are pleased with the execution of TONMYA’s launch, including nearly tripling net sales and achieving growth across our key metrics in the second quarter,” said Seth Lederman, M.D., President and Chief Executive Officer of Tonix Pharmaceuticals. “We are seeing TONMYA’s value resonate among healthcare providers and patients as the first FDA-approved treatment for fibromyalgia in 15 years. It is a first-in-class, non-opioid analgesic designed for daily bedtime administration and long-term use. We are now beginning to see coverage translate into broader patient access following the execution of agreements with commercial payers, managed Medicare, and Medicaid. Our newly expanded sales force is expected to deploy in the field by September. We believe we are well positioned to reach more of our target prescribers and support the treatment of more patients with TONMYA.”
                         
Dr. Lederman continued, “We are also progressing our clinical development pipeline priorities. We enrolled the first patient in HORIZON, our potentially pivotal Phase 2 study of TNX-102 SL in MDD. For Lyme prevention, we expect to start enrollment in the first quarter of 2027 in a Phase 2 adaptive field study after we reached alignment with FDA on the development path for TNX-4800, an investigational long-acting borreliacidal human monoclonal antibody targeting OspA on Borrelia burgdorferi.”

Commercial Updates
TONMYA (cyclobenzaprine HCl sublingual tablets): a centrally acting, non-opioid analgesic for the treatment of fibromyalgia in adults; commercially launched on November 17, 2025

Performance Across Key Metrics

• In the second quarter of 2026, key metrics include:
  • 12,592 total prescriptions, increasing 100% quarter-over-quarter. This includes bridge prescriptions that are facilitated through the Company’s digital pharmacy channel. Bridge prescriptions represent initial patient fills provided while coverage determinations are pending and do not immediately generate net product revenue.
  • New patient prescriptions increased 36% quarter-over-quarter.
  • Refills increased 207% quarter-over-quarter.

Payer Access and Coverage

• The Company is prioritizing ongoing engagement with commercial payers, managed Medicare, and Medicaid to increase access:
  • Tonix announced commercial payer agreements with two leading GPOs in May and June 2026, providing access to a combined approximate 52 million lives (29% of the total commercial lives in the U.S.).
  • Currently, total coverage for TONMYA across commercial, managed Medicare, and Medicaid channels represents approximately 136 million covered lives (~43% of the approximately 314 million covered lives in the U.S.).  
  • When the managed Medicare payer coverage agreement goes into effect on January 1, 2027, it will add approximately nine million Medicare lives (16% of the approximately 55 million Medicare lives in the U.S.). Total coverage will then reach approximately 145 million covered lives (~46% of the 314 million covered lives in the U.S.).
  • TONMYA is covered under Medicaid in most states, representing approximately 75 million lives.

Commercial Execution

• Following these coverage milestones and encouraging trends across launch key performance indicators, Tonix is implementing its strategy to expand the TONMYA sales force. The Company expects to deploy 50 new sales representatives in the field by September 2026, bringing the full sales force to approximately 150 people.
• In parallel, the Company is advancing marketing activities to enhance understanding of fibromyalgia and product awareness among patients and healthcare providers, as well as non-commercial medical affairs initiatives.
• In the second quarter of 2026, Tonix presented data highlighting TONMYA at the European Alliance of Associations for Rheumatology (EULAR) 2026, 2026 American Society of Clinical Psychopharmacology (ASCP) Annual Meeting, and Professional Society for Health and Outcomes Research (ISPOR 2026) Annual Meeting, as well as published a manuscript in the peer-reviewed journal, Clinical Pharmacology in Drug Development.

Key Product Pipeline Candidates: Recent Highlights

Central Nervous System (CNS) Pipeline
TNX-102 SL (cyclobenzaprine HCl sublingual tablets): in Phase 2 development for MDD

• In June 2026, Tonix enrolled the first patient in HORIZON, a potentially pivotal, 6-week, randomized, double-blind, placebo-controlled Phase 2 study of TNX-102 SL 5.6 mg as a first-line monotherapy in adults with MDD. Approximately 360 patients are expected to enroll at approximately 30 U.S. sites, with the primary endpoint of change from baseline in MADRS (Montgomery-Asberg Depression Rating Scale) total score at Week 6. TNX-102 SL targets disturbed sleep through antagonism at four neuronal receptors, an approach mechanistically distinct from currently available antidepressants.

Financial: Recent Highlights
Tonix had approximately $176.2 million of cash and cash equivalents as of June 30, 2026, compared to approximately $207.6 million as of December 31, 2025. Net cash used in operating activities was approximately $84.6 million for the six months ended June 30, 2026, compared to $31.4 million for the same period in 2025.

Subsequent to quarter-end, the Company raised $3.7 million in proceeds under its At-the-Market facility.

The Company believes that its cash resources as of June 30, 2026, together with the net proceeds that it raised from equity offerings in the third quarter of 2026 to date, will meet its planned operating and capital expenditure requirements into early second quarter of 2027.

As of August 7, 2026, the Company had 17,151,024 shares of common stock outstanding.

Second Quarter 2026 Financial Results
Net product revenue for the second quarter 2026 was approximately $13.5 million, compared to $2.0 million for the same period in 2025, and consisted of combined net sales of TONMYA, Zembrace® SymTouch®, and Tosymra®. Net revenue from sales of TONMYA for the second quarter was approximately $11.0 million. Net revenue from sales of Zembrace SymTouch and Tosymra was approximately $2.5 million, compared to $2.0 million for the same quarter in 2025. Cost of sales for the second quarter 2026 was approximately $0.7 million, compared to $3.3 million for the same period in 2025. The decrease in the cost of sales is predominantly driven by a change in product mix and a write-off related to the migraine products in 2025.

Research and development expenses for the second quarter 2026 were approximately $19.4 million, compared to $10.8 million for the same period in 2025. The increase of $8.6 million was primarily attributable to higher manufacturing and clinical trial costs associated with advancing the Company's prioritized pipeline programs, as well as increased employee-related costs reflecting expanded headcount.

Selling, general, and administrative expenses for the second quarter 2026 were approximately $36.0 million, compared to $16.2 million for the same period in 2025. The increase of $19.8 million was primarily attributable to sales and marketing investment supporting the commercial launch of TONMYA and the Company's migraine products, together with increased employee-related and professional expenses.

Net loss available to common stockholders was $40.6 million, or $2.44 per basic and diluted share, for the second quarter 2026, compared to net loss available to common stockholders of $28.3 million, or $3.86 per basic and diluted share, for the same period in 2025. The basic and diluted weighted average common shares outstanding for the second quarter 2026 was 16,635,254 compared to 7,327,257 shares for the same period in 2025.
