About PrimeC
PrimeC, NeuroSense’s lead drug candidate, is a novel extended-release oral formulation composed of a unique fixed-dose combination of two FDA-approved drugs: ciprofloxacin and celecoxib. PrimeC is designed to synergistically target several key mechanisms of ALS and AD, that contribute to neuron degeneration, inflammation, iron accumulation and impaired ribonucleic acid (“RNA”) regulation to potentially inhibit the progression of ALS and AD.
About ALS
Amyotrophic lateral sclerosis (“ALS”) is an incurable neurodegenerative disease that causes complete paralysis and death within 2-5 years from diagnosis. Every year, more than 5,000 people are diagnosed with ALS in the U.S. alone, with an annual disease burden of $1 billion. The number of people living with ALS is expected to grow by 24% by 2040 in the U.S. and EU.

Tegoprubart-treated patients maintained higher mean eGFR over time, including a statistically significant approximately 12 mL/min/1.73 m² advantage at month 18 versus tacrolimus (74 vs. 61 mL/min/1.73 m²; p<0.05)
No biopsy-proven acute rejection (BPAR) events were observed in tegoprubart-treated patients after the first six months post-transplant, compared with seven BPAR events (9.4% of tacrolimus-treated patients) reported in the tacrolimus arm
Patient-reported outcomes at 52 weeks favored tegoprubart, with statistically significant improvements versus tacrolimus on two validated measures of symptom burden
Conference call and webcast to be held today at 8:00 a.m. ET
IRVINE, Calif., June 22, 2026 (GLOBE NEWSWIRE) — Eledon Pharmaceuticals, Inc. (“Eledon”) (Nasdaq: ELDN) today announced new long-term data from its Phase 2 BESTOW clinical program evaluating tegoprubart in patients undergoing kidney transplantation, presented in oral and poster presentations at the American Transplant Congress (ATC) taking place June 20-24, 2026, in Boston, Massachusetts. The presentations highlight updated results from the Phase 2 BESTOW trial and new long-term follow-up data from the Phase 2 BESTOW extension study.
“These long-term data further strengthen our belief that tegoprubart has the potential to redefine the standard of care in transplant immunomodulation,” said David-Alexandre C. Gros, M.D., Chief Executive Officer of Eledon. “A statistically significant kidney function benefit at 18 months, no observed BPAR events after six months in tegoprubart-treated patients, favorable long-term safety and tolerability, and improved patient-reported outcomes collectively reinforce tegoprubart’s emerging, differentiated clinical profile as we prepare to advance into Phase 3 development.”
“For kidney transplant recipients, success is measured not only by preventing rejection, but by preserving kidney function and maintaining quality of life over the long term,” said Andrew Adams, M.D., Ph.D., Professor of Surgery and Chief, Division of Transplantation, John S. Najarian Surgical Chair in Clinical Transplantation, Department of Surgery, University of Minnesota. “These data are especially encouraging because tegoprubart was associated with sustained kidney function and improvements in patient-reported measures of symptom burden compared with tacrolimus. Providing an effective alternative to tacrolimus-based immunosuppression remains one of the most important unmet needs in kidney transplantation, particularly because lifelong immunosuppression can affect both long-term graft survival and how patients feel and function every day.”
Efficacy Results
Among patients who completed 12 months of treatment in the BESTOW study, 96% (49/51) of tegoprubart-treated patients and 86% (48/56) of tacrolimus-treated patients entered the BESTOW long-term extension study. As of the data cutoff, mean follow-up was 21 months, with: 89 patients followed through 18 months, 20 patients followed through 24 months, and the longest-followed ongoing patient followed for approximately 33 months.
Kidney graft function, as assessed by estimated glomerular filtration rate (eGFR), stabilized after the first month of treatment and remained higher in tegoprubart-treated patients than in tacrolimus-treated patients at each reported time point. At month 18, tegoprubart-treated patients demonstrated a statistically significant approximately 12 mL/min/1.73 m² higher mean eGFR compared with tacrolimus-treated patients (74 vs. 61 mL/min/1.73 m²; p<0.05).
No biopsy-proven acute rejection (BPAR) events were observed in tegoprubart-treated patients after the first six months of treatment. In the tacrolimus arm, seven of 11 total BPAR events (approximately 64% of BPAR events) occurred after six months, including two events after 12 months: one new case of active antibody-mediated rejection (aAMR) and one recurrent case of active T-cell-mediated rejection with aAMR.
Patient-reported outcome measures demonstrated lower symptom burden among tegoprubart-treated patients compared with tacrolimus-treated patients at 52 weeks, with statistically significant improvements on the Modified Transplant Symptom Occurrence and Symptom Distress Scale (MTSOSD-59R; treatment difference: -12.2; 95% CI: -19.7, -4.6; p<0.05) and the KDQOL-36 Symptoms and Problems domain (treatment difference: 5.7; 95% CI: 1.0, 10.5; p<0.05).
In an exploratory analysis of patients who experienced rejection post-transplant, those who remained on tegoprubart maintained higher mean eGFR than tacrolimus-treated patients who experienced rejection, with the observed difference increasing from approximately 15 mL/min/1.73 m² at 12 months to approximately 25 mL/min/1.73 m² at 21 months.
Long-term follow-up from the Phase 1b study for patients treated at the 20 mg/kg dose of tegoprubart was consistent with the Phase 2 BESTOW results, with no BPAR episodes observed after six months in tegoprubart-treated patients. In the Phase 1b study, long-term data was available for 16 patients; eight patients have been followed through 24 months, and the longest-followed ongoing patient has been on tegoprubart for approximately 3.5 years.
Safety Results
In the BESTOW long-term extension study, key central nervous system and kidney-related adverse events were observed more frequently in the tacrolimus arm than in the tegoprubart arm, including headache (12% vs. 2%), extremity pain (10% vs. 0%), fall or loss of balance (6% vs. 0%), and acute kidney injury (6% vs. 2%), respectively.
Diarrhea was observed more frequently in the tacrolimus arm than in the tegoprubart arm during long-term follow-up (21% vs. 10%, respectively). This pattern was consistent with the first-year BESTOW results, in which diarrhea was reported in 34% of tacrolimus-treated patients vs. in 22% of tegoprubart-treated patients.
No graft loss, no progressive multifocal leukoencephalopathy (PML), no post-transplant lymphoproliferative disorder (PTLD), no BK or CMV nephropathy/disease, and no new malignancies were reported in the BESTOW long-term extension study. No new proteinuria was reported on the tegoprubart arm. One death occurred in the tegoprubart arm and was not attributed to study drug.
Next Steps
Following a successful FDA End-of-Phase 2 meeting, Eledon has established the regulatory framework for its Phase 3 kidney transplantation program and plans to initiate Phase 3 clinical development of tegoprubart in late 2026. The Phase 3 primary endpoint is expected to be non-inferiority versus tacrolimus at 52 weeks on a composite of BPAR, graft loss and death. The Phase 3 study will also incorporate key learnings from the Phase 2 BESTOW trial and ongoing long-term extension study, including evidence of sustained kidney function benefit, favorable rejection outcomes, and improved patient-reported outcomes.

Georgia’s only National Cancer Institute (NCI)-designated Comprehensive Cancer Center; well recognized at the forefront of cancer innovation and discovery nationwide
CHICAGO, June 18, 2026 (GLOBE NEWSWIRE) — MAIA Biotechnology, Inc. (NYSE American: MAIA) (“MAIA”, the “Company”), a clinical-stage biopharmaceutical company focused on developing targeted immunotherapies for cancer, today announced that the third U.S. clinical site in its Phase 2 THIO-101 expansion trial, Winship Cancer Institute of Emory University (“Winship”), is activated and now enrolling patients. The trial studies MAIA’s lead investigational telomere-targeting agent, ateganosine, as a third-line (3L) treatment for non-small cell lung cancer (NSCLC).
Matthew Failor, Director of Clinical Operations for MAIA, commented, “Winship is Georgia’s only National Cancer Institute (NCI)-designated Comprehensive Cancer Center and is recognized at the forefront of cancer innovation and discovery nationwide. Winship offers a renowned thoracic oncology clinical research program with a proven track record in clinical trial development and conduct. With its premier medical team and extensive body of research, this cancer center is well-suited for our U.S. Phase 2 trial of ateganosine.”
The principal investigator for the THIO-101 expansion trial at Winship is Ticiana Leal, M.D., a professor in the Department of Hematology and Medical Oncology at the Emory University School of Medicine. Dr. Leal’s clinical research focuses on trials involving chemotherapy and immunotherapy agents for lung cancer.
Dr. Leal commented, “At Winship, we serve the state of Georgia and surrounding states where innovation in lung cancer treatment is a broad, underserved need. In Georgia, lung cancer is the leading cause of cancer-related deaths, with over 7,300 new cases in 2025. MAIA’s novel ateganosine agent, if approved, could address a significant gap in clinical care for the advanced-stage NSCLC patient population where there are no FDA-approved options available for treatment.”
THIO-101 is an ongoing Phase 2, open-label trial evaluating ateganosine followed by cemiplimab for NSCLC patients resistant to checkpoint inhibitors and chemotherapy. Parts A and B of the trial have shown strong early efficacy, with some patients showing survival exceeding two years, and now MAIA continues to expand the trial in the U.S.
About Ateganosine
Ateganosine (THIO, 6-thio-dG or 6-thio-2’-deoxyguanosine) is a first-in-class investigational telomere-targeting agent currently in clinical development to evaluate its activity in non-small cell lung cancer (NSCLC). Telomeres, along with the enzyme telomerase, play a fundamental role in the survival of cancer cells and their resistance to current therapies. The modified nucleotide 6-thio-2’-deoxyguanosine induces telomerase-dependent telomeric DNA modification, DNA damage responses, and selective cancer cell death. Ateganosine-damaged telomeric fragments accumulate in cytosolic micronuclei and activates both innate (cGAS/STING) and adaptive (T-cell) immune responses. The sequential treatment of ateganosine followed by PD-(L)1 inhibitors resulted in profound and persistent tumor regression in advanced, in vivo cancer models by induction of cancer type–specific immune memory. Ateganosine is presently developed as a second or later line of treatment for NSCLC for patients that have progressed beyond the standard-of-care regimen of existing checkpoint inhibitors.
About THIO-101 Phase 2 Clinical Trial
THIO-101 is a multicenter, open-label, dose finding Phase 2 clinical trial. It is the first trial designed to evaluate ateganosine’s anti-tumor activity when followed by PD-(L)1 inhibition. The trial is testing the hypothesis that low doses of ateganosine administered prior to cemiplimab (Libtayo®) will enhance and prolong immune response in patients with advanced NSCLC who previously did not respond or developed resistance and progressed after first-line treatment regimen containing another checkpoint inhibitor. The trial design has two primary objectives: (1) to evaluate the safety and tolerability of ateganosine administered as an anticancer compound and a priming immune activator (2) to assess the clinical efficacy of ateganosine using Overall Response Rate (ORR) as the primary clinical endpoint. The expansion of the study will assess overall response rates (ORR) in advanced NSCLC patients receiving third line (3L) therapy who were resistant to previous checkpoint inhibitor treatments (CPI) and chemotherapy. Treatment with ateganosine followed by cemiplimab (Libtayo®) has shown an acceptable safety profile to date in a heavily pre-treated population. For more information on this Phase II trial, please visit ClinicalTrials.gov using the identifier NCT05208944.
About MAIA Biotechnology, Inc.
MAIA is a targeted therapy, immuno-oncology company focused on the development and commercialization of potential first-in-class drugs with novel mechanisms of action that are intended to meaningfully improve and extend the lives of people with cancer. Our lead program is ateganosine (THIO), a potential first-in-class cancer telomere targeting agent in clinical development for the treatment of NSCLC patients with telomerase-positive cancer cells.

Real-world analysis of three years of closed claims data from Symphony Health, focused on the third year of the study (2023-2024), comprised of more than 261,000 U.S. adults with fibromyalgia
Data demonstrate a substantial and persistent health burden associated with prescribed opioid use among adults with fibromyalgia
Tonix commercially launched TONMYA® in November 2025, the first new fibromyalgia drug for adults in the U.S. in over 15 years approved by the U.S. Food and Drug Administration (FDA)
BERKELEY HEIGHTS, N.J., May 28, 2026 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (“Tonix” or the “Company”), a fully-integrated, commercial-stage biotechnology company, presented data from a real-world claims analysis of opioid use in U.S. adults with fibromyalgia at the 2026 ASCP Annual Meeting, held May 26-29, 2026, in Miami Beach, Florida.
“Opioids remain widely prescribed for fibromyalgia despite long-standing guidelines that discourage their use due to lack of efficacy, a growing concern that they worsen fibromyalgia symptoms and the risk of dependence,1-6” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “The discrepancy between real-world practice and evidence-based recommendations reveals a gap in knowledge and an urgent need to educate health care prescribers about the nature of fibromyalgia and the availability of non-opioid, FDA-approved medicines. Tonix is currently executing on the launch of TONMYA® (cyclobenzaprine HCl sublingual tablets), a first-in-class, first-line, non-opioid analgesic medicine FDA approved for daily bedtime administration and long-term use in adults with fibromyalgia.”
Data presented at ASCP 2026 represent a retrospective cohort study using the Symphony Health closed claims database, encompassing administrative medical and pharmacy claims collected between April 2021 and April 2024, to evaluate opioid and benzodiazepine use among adults diagnosed with fibromyalgia (ICD-10-CM diagnosis code M79.7). The study’s objective was to quantify opioid and benzodiazepine use in patients diagnosed with fibromyalgia and characterize patients by age, insurance coverage, and polypharmacy. The Year 3 cohort (April 2023 to March 2024) included 261,776 adult patients, with a mean age of 52.3 years. The cohort was predominantly female (92.1%).
Among patients with Commercial or Medicare Advantage insurance, 40.2% of patients were prescribed at least one opioid, with most claims for tramadol (13.7%), followed by oxycodone (13.1%). Among Medicaid patients, 38.8% were prescribed at least one opioid, with most claims for oxycodone (15.7%), followed by tramadol (11.1%). The Medication Possession Ratio (MPR) for opioid use was similar for Commercial or Medicare Advantage patients (0.39) and Medicaid patients (0.40). Opioid use showed the highest prevalence in older age groups: 61-65 years (43.1%), 66-70 years (39.2%), 71-75 years (38.5%), and >75 years (34.4%), and was lower, but still common for younger adults 18-25 years (20.9%). Concomitant opioid and benzodiazepine use was similar in patients covered under Medicare Advantage or Commercial insurance (19.1%) and Medicaid patients (20.4%).

INDICATION TONMYA is indicated for the treatment of fibromyalgia in adults.
CONTRAINDICATIONS TONMYA is contraindicated:
In patients with hypersensitivity to cyclobenzaprine or any inactive ingredient in TONMYA. Hypersensitivity reactions may manifest as an anaphylactic reaction, urticaria, facial and/or tongue swelling, or pruritus. Discontinue TONMYA if a hypersensitivity reaction is suspected. With concomitant use of monoamine oxidase (MAO) inhibitors or within 14 days after discontinuation of an MAO inhibitor. Hyperpyretic crisis seizures and deaths have occurred in patients who received cyclobenzaprine (or structurally similar tricyclic antidepressants) concomitantly with MAO inhibitors drugs.
During the acute recovery phase of myocardial infarction, and in patients with arrhythmias, heart block or conduction disturbances, or congestive heart failure. In patients with hyperthyroidism.
WARNINGS AND PRECAUTIONS Embryofetal toxicity: Based on animal data, TONMYA may cause neural tube defects when used two weeks prior to conception and during the first trimester of pregnancy. Advise females of reproductive potential of the potential risk and to use effective contraception during treatment and for two weeks after the final dose. Perform a pregnancy test prior to initiation of treatment with TONMYA to exclude use of TONMYA during the first trimester of pregnancy.
Serotonin syndrome: Concomitant use of TONMYA with selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants, tramadol, bupropion, meperidine, verapamil, or MAO inhibitors increases the risk of serotonin syndrome, a potentially life-threatening condition. Serotonin syndrome symptoms may include mental status changes, autonomic instability, neuromuscular abnormalities, and/or gastrointestinal symptoms. Treatment with TONMYA and any concomitant serotonergic agent should be discontinued immediately if serotonin syndrome symptoms occur and supportive symptomatic treatment should be initiated. If concomitant treatment with TONMYA and other serotonergic drugs is clinically warranted, careful observation is advised, particularly during treatment initiation or dosage increases.
Tricyclic antidepressant-like adverse reactions: Cyclobenzaprine is structurally related to TCAs. TCAs have been reported to produce arrhythmias, sinus tachycardia, prolongation of the conduction time leading to myocardial infarction and stroke. If clinically significant central nervous system (CNS) symptoms develop, consider discontinuation of TONMYA. Caution should be used when TCAs are given to patients with a history of seizure disorder, because TCAs may lower the seizure threshold. Patients with a history of seizures should be monitored during TCA use to identify recurrence of seizures or an increase in the frequency of seizures.
Atropine-like effects: Use with caution in patients with a history of urinary retention, angle-closure glaucoma, increased intraocular pressure, and in patients taking anticholinergic drugs.
CNS depression and risk of operating a motor vehicle or hazardous machinery: TONMYA monotherapy may cause CNS depression. Concomitant use of TONMYA with alcohol, barbiturates, or other CNS depressants may increase the risk of CNS depression. Advise patients not to operate a motor vehicle or dangerous machinery until they are reasonably certain that TONMYA therapy will not adversely affect their ability to engage in such activities. Oral mucosal adverse reactions: In clinical studies with TONMYA, oral mucosal adverse reactions occurred more frequently in patients treated with TONMYA compared to placebo. Advise patients to moisten the mouth with sips of water before administration of TONMYA to reduce the risk of oral sensory changes (hypoesthesia). Consider discontinuation of TONMYA if severe reactions occur.
ADVERSE REACTIONS The most common adverse reactions (incidence ≥2% and at a higher incidence in TONMYA-treated patients compared to placebo-treated patients) were oral hypoesthesia, oral discomfort, abnormal product taste, somnolence, oral paresthesia, oral pain, fatigue, dry mouth, and aphthous ulcer.
DRUG INTERACTIONS MAO inhibitors: Life-threatening interactions may occur. Other serotonergic drugs: Serotonin syndrome has been reported. CNS depressants: CNS depressant effects of alcohol, barbiturates, and other CNS depressants may be enhanced.
Tramadol: Seizure risk may be enhanced. Guanethidine or other similar acting drugs: The antihypertensive action of these drugs may be blocked.
USE IN SPECIFIC POPULATIONS Pregnancy: Based on animal data, TONMYA may cause fetal harm when administered to a pregnant woman. The limited amount of available observational data on oral cyclobenzaprine use in pregnancy is of insufficient quality to inform a TONMYA-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Advise pregnant women about the potential risk to the fetus with maternal exposure to TONMYA and to avoid use of TONMYA two weeks prior to conception and through the first trimester of pregnancy. Report pregnancies to the Tonix Medicines, Inc., adverse-event reporting line at 1-888-869-7633 (1-888-TNXPMED).
Lactation: A small number of published cases report the transfer of cyclobenzaprine into human milk in low amounts, but these data cannot be confirmed. There are no data on the effects of cyclobenzaprine on a breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for TONMYA and any potential adverse effects on the breastfed child from TONMYA or from the underlying maternal condition.
Pediatric use: The safety and effectiveness of TONMYA have not been established. Geriatric patients: Of the total number of TONMYA-treated patients in the clinical trials in adult patients with fibromyalgia, none were 65 years of age and older. Clinical trials of TONMYA did not include sufficient numbers of patients 65 years of age and older to determine whether they respond differently from younger adult patients.
Hepatic impairment: The recommended dosage of TONMYA in patients with mild hepatic impairment (HI) (Child Pugh A) is 2.8 mg once daily at bedtime, lower than the recommended dosage in patients with normal hepatic function. The use of TONMYA is not recommended in patients with moderate HI (Child Pugh B) or severe HI (Child Pugh C). Cyclobenzaprine exposure (AUC) was increased in patients with mild HI and moderate HI compared to subjects with normal hepatic function, which may increase the risk of TONMYA-associated adverse reactions.
Please see additional safety information in the full Prescribing Information. To report suspected adverse reactions, contact Tonix Medicines, Inc. at 1-888-869-7633, or the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
Novel, potent pan-viral inhibitors targeting the viral replication complex are under development for the treatment of hantavirus, bunyavirus and influenza
Hantavirus and bunyavirus infections represent significant unmet medical needs, contribute to ongoing global outbreaks and have no approved treatments or vaccines
BOTHELL, Wash., May 26, 2026 (GLOBE NEWSWIRE) — Cocrystal Pharma, Inc. (Nasdaq: COCP) (“Cocrystal” or the “Company”) announces that its novel direct-acting antivirals demonstrate pan-viral activity against multiple viruses, including hantavirus, bunyavirus and influenza. These antiviral molecules target a highly conserved region of the viral replication enzyme, specifically the L-protein of Andes hantavirus, which is essential for viral replication and transcription. In vitro potency data show superior activity (IC50 <50 nM) against hantaan virus, which is closely related to the Andes hantavirus strain associated with recent outbreaks.
“We are thoughtfully leveraging our expertise in viral replication enzymes and structure-based drug discovery to develop the next generation of pan-viral replication inhibitors. Our first pan-viral protease inhibitor, CDI-988, recently advanced to a Phase 1b norovirus challenge study in the United States. Our research efforts have expanded to novel pan-viral replication inhibitors with the goal of developing a novel pan-viral lead molecule for multiple viral diseases caused by hantaviruses, bunyaviruses and influenza viruses,” said Sam Lee, Ph.D., President and co-CEO of Cocrystal Pharma. “We are encouraged by our initial in vitro potency data against hantavirus and plan to evaluate in vitro antiviral activity against the Andes hantavirus replication enzyme. We look forward to exploring collaborations and partnerships to address these urgent unmet needs.”
The Andes hantavirus was recently responsible for a deadly outbreak on a cruise ship, infecting up to 11 passengers and crew, resulting in three deaths. Hantaviruses are primarily transmitted by rodents, although human-to-human transmission can occur through prolonged close contact. Andes hantavirus, a member of the genus Hantavirus, is endemic in Argentina and Chile and causes hantavirus cardiopulmonary syndrome (HCPS), which is associated with a case fatality rate of up to 50%. Currently, there are no approved antivirals or vaccines for Andes hantavirus or other hantaviruses.

Company Aligns Resources with Programs Demonstrating Strong Clinical, Regulatory, and Market Momentum
ATLANTA, GA — May 26, 2026 — GeoVax Labs, Inc. (Nasdaq: GOVX), a clinical-stage biotechnology company developing immunotherapies and vaccines, today announced a strategic prioritization of its development portfolio to concentrate resources on its lead programs, GEO-MVA and Gedeptin®, reflecting increasing clinical, regulatory, and market alignment across these programs. As part of this decision, the Company has elected to discontinue active development activities related to its GEO-CM04S1 COVID-19 vaccine candidate. This decision was not related to any safety concerns with the vaccine but reflects the continued evolution and contraction of the global COVID-19 vaccine market, and GeoVax’s focus on programs with clearer regulatory pathways, stronger demand visibility, and more immediate commercialization potential. GeoVax emphasized that portfolio prioritization is a standard and essential practice within the biotechnology industry, enabling companies to align resources with the highest-value opportunities as market conditions and scientific landscapes evolve.
“GeoVax is at an important inflection point, and this decision reflects a deliberate and disciplined focus on the programs we believe can deliver the greatest near-term and long-term value,” said David Dodd, Chairman and Chief Executive Officer of GeoVax. “As GEO-MVA advances toward clinical validation and potential commercialization, and as Gedeptin gains relevance within emerging immuno-oncology treatment paradigms, we are aligning our resources to support focused execution against these high-potential opportunities.”
GEO-MVA: Expedited Pathway and Near-Term Commercial Opportunity
GEO-MVA, GeoVax’s Modified Vaccinia Ankara (MVA) vaccine candidate targeting mpox and smallpox, is advancing under an expedited regulatory pathway supported by European Medicines Agency (EMA) scientific advice. This approach enables potential approval based on a single pivotal immunobridging study demonstrating non-inferiority to an approved MVA vaccine – significantly accelerating development timelines and reducing clinical risk.
The program has clinical-grade material manufactured and released in preparation for the planned Phase 3 immunobridging study. Following successful completion, GEO-MVA is expected to advance toward regulatory submission and potential commercialization within a streamlined timeframe, including potential Emergency Use Licensing.
GeoVax has initiated outreach with global procurement and preparedness stakeholders – including government agencies, international organizations, and biodefense programs – supporting potential vaccine supply agreements aligned with national stockpiling and outbreak response needs. These activities position GEO-MVA to serve as a critical additional supplier of MVA-vaccine supporting supply-chain resilience and biodefense preparedness.
Gedeptin®: Aligned with Emerging Immuno-Oncology Treatment Paradigm
Gedeptin®, GeoVax’s gene-directed enzyme prodrug therapy (GDEPT) platform, is being advanced in alignment with a rapidly evolving oncology landscape, highlighted by the landmark KEYNOTE-689 Phase 3 trial demonstrating improved event-free survival with neoadjuvant checkpoint inhibitor therapy in resectable head and neck cancers.
GeoVax’s planned Phase 2 study (AdPNP-203) will evaluate Gedeptin in combination with pembrolizumab and fludarabine in a neoadjuvant setting, with the objective of enhancing tumor immune visibility and improving clinical outcomes.
Gedeptin’s tumor-targeting mechanism is designed to significantly damage or destroy treated lesions through the localized, in situ generation of a potent chemotherapeutic agent. In addition, Gedeptin appears to sensitize tumors to checkpoint inhibitors, likely through the exposure and release of neoantigens from treated lesions, thereby enhancing responses in both treated and untreated lesions. This mechanism may expand response rates and improve durability of outcomes in patients who derive limited benefit from checkpoint inhibition alone. These developments underscore the growing relevance of Gedeptin within this evolving treatment paradigm and support GeoVax’s decision to prioritize its advancement within the Company’s portfolio.
“This is a strategic step forward for GeoVax,” Dodd added. “By concentrating our efforts on GEO-MVA and maintaining our oncology innovation with Gedeptin, we believe we are positioning the Company for a more focused, execution-driven path toward late-stage development, commercialization and long-term value creation”.

Real-world analysis of three years of closed claims data from Symphony Health focused on the third year of the study (2023-2024), comprised of more than 261,000 U.S. adults with fibromyalgia
Data underscore high comorbidity burden, multimodal treatment approach, and extensive healthcare resource utilization (HCRU) among patients with fibromyalgia
Tonix commercially launched TONMYA® in November 2025, the first new fibromyalgia drug for adults in the U.S. approved in over 15 years
BERKELEY HEIGHTS, N.J., May 26, 2026 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (“Tonix” or the “Company”), a fully integrated, commercial biotechnology company, presented data from a real-world claims analysis characterizing U.S. adults with fibromyalgia in a poster at ISPOR 2026, the Professional Society for Health Economics and Outcomes Research’s annual meeting, held May 17-20, 2026, in Philadelphia, Pennsylvania.
“Fibromyalgia is a chronic pain disorder characterized by widespread musculoskeletal pain, fatigue, sleep disturbance, cognitive dysfunction, and somatic symptoms, leading to substantial management challenges,”1-4 said Seth Lederman, M.D., President and Chief Executive Officer of Tonix Pharmaceuticals. “More than 10 million adults in the U.S. suffer from fibromyalgia. In response to fibromyalgia’s complex and persistent symptoms, and extensive comorbidities, fibromyalgia patients face rotating treatment approaches, and high HCRU. These findings highlight the need for comprehensive disease management and more effective therapeutic interventions to reduce the clinical and economic burden of fibromyalgia. Tonix is focused on the commercial launch of TONMYA, a first-in-class, first-line, non-opioid analgesic medicine designed for daily bedtime administration and long-term use.”
Data presented at ISPOR 2026 represent a retrospective, multi-year, multi-cohort study using the Symphony Health closed claims database, encompassing administrative medical and pharmacy claims collected between April 2021 and April 2024. The study’s objective was to evaluate real-world characteristics, including demographics, comorbidities, and HCRU among adults diagnosed with fibromyalgia (ICD-10-CM diagnosis code M79.7). The Year 3 cohort (April 2023 to March 2024) included 261,776 adult patients, with a median age of 53 years. Most patients were female (92.1%). Patients were White non-Hispanic (49.6%), Hispanic (22.4%), Other (19.6%), and Black (8.3%).
Comorbidity burden was high, with 93.2% of patients having at least one fibromyalgia-related comorbidity, most commonly anxiety/depression (63.9%), dorsalgia/back pain (56.5%), hypertensive diseases (51.4%), and joint pain (48.4%). Among the 90.3% of patients with at least one co-existing condition (or comorbidity), 36.2% had four or more, and subgroups including Black/Brown women, women on opioids, women with gut health issues, and older women with sleep issues all carried higher rates of comorbidity than the overall cohort. Among insured patients (n=92,157), HCRU was extensive, and inpatient services represented the largest component of healthcare costs at $29,896 per patient annually, followed by pharmacy ($9,453) and outpatient ($6,196) costs, demonstrating the large burden on commercial and public healthcare programs. Antidepressants were the most frequently used medication class (48.2%), followed by NSAID analgesics (43.4%), anticonvulsants (41.6%), gastric acid secretion reducers (41.5%), skeletal muscle relaxants (40.7%), and opioid analgesics (39.4%). The medication use reflects reliance on multimodal pharmacologic strategies to manage fibromyalgia-related symptoms in routine clinical practice.

INDICATION TONMYA is indicated for the treatment of fibromyalgia in adults.
CONTRAINDICATIONS TONMYA is contraindicated:
In patients with hypersensitivity to cyclobenzaprine or any inactive ingredient in TONMYA. Hypersensitivity reactions may manifest as an anaphylactic reaction, urticaria, facial and/or tongue swelling, or pruritus. Discontinue TONMYA if a hypersensitivity reaction is suspected. With concomitant use of monoamine oxidase (MAO) inhibitors or within 14 days after discontinuation of an MAO inhibitor. Hyperpyretic crisis seizures and deaths have occurred in patients who received cyclobenzaprine (or structurally similar tricyclic antidepressants) concomitantly with MAO inhibitors drugs.
During the acute recovery phase of myocardial infarction, and in patients with arrhythmias, heart block or conduction disturbances, or congestive heart failure. In patients with hyperthyroidism.
WARNINGS AND PRECAUTIONS Embryofetal toxicity: Based on animal data, TONMYA may cause neural tube defects when used two weeks prior to conception and during the first trimester of pregnancy. Advise females of reproductive potential of the potential risk and to use effective contraception during treatment and for two weeks after the final dose. Perform a pregnancy test prior to initiation of treatment with TONMYA to exclude use of TONMYA during the first trimester of pregnancy.
Serotonin syndrome: Concomitant use of TONMYA with selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants, tramadol, bupropion, meperidine, verapamil, or MAO inhibitors increases the risk of serotonin syndrome, a potentially life-threatening condition. Serotonin syndrome symptoms may include mental status changes, autonomic instability, neuromuscular abnormalities, and/or gastrointestinal symptoms. Treatment with TONMYA and any concomitant serotonergic agent should be discontinued immediately if serotonin syndrome symptoms occur and supportive symptomatic treatment should be initiated. If concomitant treatment with TONMYA and other serotonergic drugs is clinically warranted, careful observation is advised, particularly during treatment initiation or dosage increases.
Tricyclic antidepressant-like adverse reactions: Cyclobenzaprine is structurally related to TCAs. TCAs have been reported to produce arrhythmias, sinus tachycardia, prolongation of the conduction time leading to myocardial infarction and stroke. If clinically significant central nervous system (CNS) symptoms develop, consider discontinuation of TONMYA. Caution should be used when TCAs are given to patients with a history of seizure disorder, because TCAs may lower the seizure threshold. Patients with a history of seizures should be monitored during TCA use to identify recurrence of seizures or an increase in the frequency of seizures.
Atropine-like effects: Use with caution in patients with a history of urinary retention, angle-closure glaucoma, increased intraocular pressure, and in patients taking anticholinergic drugs.
CNS depression and risk of operating a motor vehicle or hazardous machinery: TONMYA monotherapy may cause CNS depression. Concomitant use of TONMYA with alcohol, barbiturates, or other CNS depressants may increase the risk of CNS depression. Advise patients not to operate a motor vehicle or dangerous machinery until they are reasonably certain that TONMYA therapy will not adversely affect their ability to engage in such activities. Oral mucosal adverse reactions: In clinical studies with TONMYA, oral mucosal adverse reactions occurred more frequently in patients treated with TONMYA compared to placebo. Advise patients to moisten the mouth with sips of water before administration of TONMYA to reduce the risk of oral sensory changes (hypoesthesia). Consider discontinuation of TONMYA if severe reactions occur.
ADVERSE REACTIONS The most common adverse reactions (incidence ≥2% and at a higher incidence in TONMYA-treated patients compared to placebo-treated patients) were oral hypoesthesia, oral discomfort, abnormal product taste, somnolence, oral paresthesia, oral pain, fatigue, dry mouth, and aphthous ulcer.
DRUG INTERACTIONS MAO inhibitors: Life-threatening interactions may occur. Other serotonergic drugs: Serotonin syndrome has been reported. CNS depressants: CNS depressant effects of alcohol, barbiturates, and other CNS depressants may be enhanced.
Tramadol: Seizure risk may be enhanced. Guanethidine or other similar acting drugs: The antihypertensive action of these drugs may be blocked.
USE IN SPECIFIC POPULATIONS Pregnancy: Based on animal data, TONMYA may cause fetal harm when administered to a pregnant woman. The limited amount of available observational data on oral cyclobenzaprine use in pregnancy is of insufficient quality to inform a TONMYA-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Advise pregnant women about the potential risk to the fetus with maternal exposure to TONMYA and to avoid use of TONMYA two weeks prior to conception and through the first trimester of pregnancy. Report pregnancies to the Tonix Medicines, Inc., adverse-event reporting line at 1-888-869-7633 (1-888-TNXPMED).
Lactation: A small number of published cases report the transfer of cyclobenzaprine into human milk in low amounts, but these data cannot be confirmed. There are no data on the effects of cyclobenzaprine on a breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for TONMYA and any potential adverse effects on the breastfed child from TONMYA or from the underlying maternal condition.
Pediatric use: The safety and effectiveness of TONMYA have not been established. Geriatric patients: Of the total number of TONMYA-treated patients in the clinical trials in adult patients with fibromyalgia, none were 65 years of age and older. Clinical trials of TONMYA did not include sufficient numbers of patients 65 years of age and older to determine whether they respond differently from younger adult patients.
Hepatic impairment: The recommended dosage of TONMYA in patients with mild hepatic impairment (HI) (Child Pugh A) is 2.8 mg once daily at bedtime, lower than the recommended dosage in patients with normal hepatic function. The use of TONMYA is not recommended in patients with moderate HI (Child Pugh B) or severe HI (Child Pugh C). Cyclobenzaprine exposure (AUC) was increased in patients with mild HI and moderate HI compared to subjects with normal hepatic function, which may increase the risk of TONMYA-associated adverse reactions.
Please see additional safety information in the full Prescribing Information. To report suspected adverse reactions, contact Tonix Medicines, Inc. at 1-888-869-7633, or the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
Company Highlights Potential Role of MVA-Based Vaccine Technologies in Addressing Emerging Hemorrhagic Fever Threats, Including Ebola and Marburg Viruses
ATLANTA, GA – May 20, 2026 – GeoVax Labs, Inc. (Nasdaq: GOVX), a clinical-stage biotechnology company developing vaccines and immunotherapies against infectious diseases and cancer, today commented on the rapidly evolving Bundibugyo Ebola virus (BDBV) outbreak in Central Africa and the broader implications for global infectious disease preparedness and biodefense infrastructure.
The recent declaration by the World Health Organization (WHO) of a Public Health Emergency of International Concern (PHEIC) related to the outbreak has intensified concerns regarding global readiness for emerging viral threats, particularly less common Ebola species for which no broadly licensed vaccines currently exist.
GeoVax noted that its MVA-based hemorrhagic fever vaccine development programs have previously demonstrated encouraging preclinical protection signals across multiple filovirus targets, including Ebola and Marburg viruses. Key findings from previously completed studies include:
MVA-EBOV (Zaire Ebola): Demonstrated single-dose protection against lethal Zaire Ebola virus challenge in non-human primates, supporting the potential of MVA-based rapid-response filovirus vaccines.
MVA-SUDV (Sudan Ebola): Demonstrated protective efficacy in multiple preclinical challenge models, including single-dose protection in guinea pigs and survival benefit in non-human primates.
MVA-MARV (Marburg): Demonstrated significant survival protection in rigorous non-human primate challenge studies, supporting further development of MVA-based Marburg vaccine strategies.
“These outbreaks collectively reinforce a growing reality: preparedness against one viral strain does not necessarily ensure preparedness against the next,” said David A. Dodd. “The world is entering an era of continuous infectious disease emergence and re-emergence, where scalable vaccine platforms, diversified manufacturing capabilities, and flexible biodefense infrastructure will become increasingly important.”
Unlike prior Ebola outbreaks involving the Zaire ebolavirus species, the current outbreak involves the Bundibugyo species, which presently lacks a specifically approved vaccine for broad deployment. Public health experts have increasingly noted that the outbreak exposes limitations in existing strain-specific preparedness strategies and reinforces the importance of adaptable vaccine technologies capable of addressing multiple high-consequence pathogens.
The Company believes that MVA-based vaccine platforms may offer several important strategic advantages in responding to emerging infectious disease threats, including:
established safety and tolerability profiles,
flexibility for incorporation of multiple antigens,
potential applicability across multiple viral families,
suitability for rapid adaptation, and
the potential for development of multivalent single-dose vaccine approaches targeting multiple hemorrhagic fever pathogens simultaneously.
“Outbreaks involving Ebola, mpox, Marburg, hantavirus, and other emerging pathogens collectively reinforce the growing need for platform technologies capable of supporting rapid response against evolving threats,” added Mr. Dodd. “The lessons emerging from the current outbreak extend beyond Ebola itself and increasingly point toward the need for resilient, scalable, geographically distributed vaccine manufacturing capacity and second-source biodefense preparedness.”
GeoVax is currently advancing GEO-MVA, its MVA-based vaccine candidate targeting mpox and smallpox, designed to support growing global demand for orthopox preparedness while contributing to the development of domestic U.S.-based MVA manufacturing capability. The pivotal Phase 3 immunobridging study of GEO-MVA, in support of an expedited regulatory path provided by the European Medicines Agency (EMA), is scheduled to initiate in Q4 2026, with data results anticipated within approximately three months following trial initiation.
The Company believes the broader strategic relevance of MVA-based technologies continues to expand as governments and public health organizations increasingly prioritize:
supply-chain resilience,
domestic manufacturing,
flexible vaccine platforms, and
preparedness against multiple emerging infectious disease threats.

IRVINE, Calif., May 13, 2026 (GLOBE NEWSWIRE) — Eledon Pharmaceuticals, Inc. (“Eledon”) (Nasdaq: ELDN) today reported its first quarter 2026 operating and financial results and provided recent business highlights.
“In the first quarter of 2026, we achieved significant milestones in our tegoprubart program, including important data updates in kidney and islet cell transplantation and FDA Orphan Drug designation for tegoprubart in liver transplantation,” said David-Alexandre C. Gros, M.D., Chief Executive Officer of Eledon. “Looking ahead, we expect multiple catalysts in 2026, including regulatory engagements supporting the advancement of tegoprubart into Phase 3 development in kidney transplantation and discussions regarding a potential path to market in islet cell transplantation. We also plan to initiate several new clinical trials, including an investigator sponsored study in liver transplantation, and share new kidney transplant data from our Phase 2 BESTOW long-term extension study, building on encouraging 24-month Phase 1b results that demonstrated a durable safety profile and improved graft function.”
First Quarter 2026 Business Highlights
In March 2026, announced updated results from an ongoing investigator-led trial at the University of Chicago Medicine Transplant Institute evaluating tegoprubart in 12 adults with high-risk type 1 diabetes undergoing allogenic islet transplantation. All 10 patients who are more than four weeks post-transplant achieved 100% insulin independence. There were no signs of graft rejection or de novo donor-specific HLA antibodies and no evidence of nephrotoxicity, hypertension, or neurotoxicity, which are commonly associated with tacrolimus-based immunosuppression regimens, the current standard of care.
The U.S. Food and Drug Administration (FDA) granted Orphan Drug designation to tegoprubart for the prevention of allograft rejection in liver transplantation.
Presented 24-month follow-up data from eight patients enrolled in the Phase 1b trial long-term extension trial evaluating tegoprubart in kidney transplantation at the American Society of Transplant Surgeons Winter Symposium in January 2026. Results showed there were no episodes of biopsy-proven acute rejection, graft loss, death, new-onset diabetes mellitus, or de novo donor-specific antibody formation during the study period. Mean estimated glomerular filtration rate (eGFR) increased over the measurement period, from 67.0 mL/min/1.73 m2 at 12 months to 74.2 mL/min/1.73 m2 at 24 months.
2026 Anticipated Upcoming Milestones
Receive FDA guidance on the Phase 3 trial design assessing tegoprubart in kidney transplantation, followed by initiation of the Phase 3 trial pending regulatory alignment.
Report long-term data from Phase 1b and Phase 2 BESTOW studies evaluating tegoprubart in kidney transplantation.
Receive FDA regulatory guidance on the path to market for tegoprubart in islet cell transplantation and xenotransplantation.
Initiate an investigator-led study evaluating tegoprubart for the prevention of organ rejection in patients with renal dysfunction receiving an islet cell transplant.
Initiate an investigator-led study evaluating tegoprubart for the prevention of organ rejection in patients receiving a de novo liver transplant.
Initiate an investigator-led study evaluating tegoprubart for kidney transplant tolerance induction.

Dr. Lederman continued, “We also continue to meaningfully advance our mid-stage clinical programs and our earlier-stage pipeline. For TNX-4800, our investigational long-acting borreliacidal, human monoclonal antibody targeting OspA on Borrelia burgdorferi, which causes the majority of Lyme disease in the U.S., we announced positive Phase 1 data and plans for an adaptive Phase 2 field study in 2027, pending FDA agreement. We look forward to our scheduled Type C meeting with the FDA early in the third quarter of 2026 to discuss the study. We believe TNX-4800 offers several advantages over vaccines in development, including onset of protection within two days and a simpler two-dose regimen with a second booster dose two months after the first. We also expect to begin our Phase 2 study of TONMYA for the treatment of Major Depressive Disorder (MDD) mid-year. Our other programs across CNS, infectious disease, immunology, and rare disease remain well positioned for near-term milestones.”
Commercial Updates
TONMYA (cyclobenzaprine HCl sublingual tablets): a centrally acting, non-opioid analgesic for the treatment of fibromyalgia in adults
On November 17, 2025, TONMYA became commercially available, following U.S. FDA approval in August 2025 for the treatment of fibromyalgia in adults. TONMYA is the first new prescription medicine approved for fibromyalgia in more than 15 years. The approval was based on two double-blind, randomized, placebo-controlled Phase 3 clinical studies of nearly 1,000 patients that demonstrated durable and statistically significant reduction in daily pain scores compared to placebo. There are now approximately 100 TONMYA sales reps in the field.
In the first quarter of 2026, the first full quarter since launch, key metrics include:
2,145 unique healthcare providers prescribed TONMYA to patients.
3,588 unique patients initiated treatment with TONMYA.
Approximately 5,400 prescriptions were filled. This includes bridge prescriptions that are facilitated through the Company’s specialty pharmacy channel. Bridge prescriptions represent initial patient fills provided while coverage determinations are pending and do not immediately generate net product revenue.
For the period beginning November 17, 2025, through April 24, 2026, cumulative key metrics include:
More than 2,700 unique healthcare providers have prescribed TONMYA to patients.
Approximately 5,618 unique patients have initiated treatment with TONMYA.
For the period beginning November 17, 2025, through May 1, 2026, cumulative key metrics include:
Approximately 11,016 prescriptions were filled. This includes bridge prescriptions that are facilitated through the Company’s specialty pharmacy channel.
Repeat prescriber and patient refill trends are encouraging.
The Company is prioritizing engagement with commercial payers, Medicare, and Medicaid to increase access:
In May 2026, Tonix secured commercial payer coverage with its first managed care partnership agreement with a leading GPO, which will provide access for approximately 35 million U.S. patients (20% of ~177 million commercial lives in the U.S.)
To date, TONMYA is covered under Medicaid in 38 states, for approximately 55 million lives, representing 73% of the roughly 75 million Medicaid lives.
Tonix has a robust patient access program and support services in place, including a TONMYA savings card, copay assistance, and prior authorization support, intended to reduce access barriers during early commercialization.
To educate healthcare providers (HCPs), the Company held a multidisciplinary dialogue about TONMYA via a national webcast. Tonix also launched a national speaker training program with approximately 100 HCPs to maximize peer-to-peer speaker programs expected to occur across target specialties and regions this year.
As part of a commitment to continued clinical evidence generation and education, Tonix presented clinical data on TONMYA at the 8th International Congress on Controversies in Fibromyalgia, 2026 American Academy of Pain Medicine (AAPM) PainConnect Annual Meeting, and 2026 Non-Opioid Pain Therapeutics Summit. The Company also published two articles in the peer-reviewed journal, Clinical Pharmacology in DrugDevelopment.
