CHICAGO, June 01, 2026 (GLOBE NEWSWIRE) — MAIA Biotechnology, Inc. (NYSE American: MAIA) (“MAIA”, the “Company”), a clinical-stage biopharmaceutical company focused on developing targeted immunotherapies for cancer, delivered a poster presentation on May 31, 2026, featuring the methodology and study design for its pivotal Phase 3 clinical trial (THIO-104) at the 2026 Annual Meeting of the American Society of Clinical Oncology (ASCO 2026), being held May 29 – June 2, 2026, in MAIA’s home city of Chicago, Illinois. THIO-104 evaluates the efficacy of MAIA’s telomere targeting agent, ateganosine, administered in sequence with a checkpoint inhibitor (CPI) in third-line non-small cell lung cancer (NSCLC) patients resistant to CPIs and chemotherapy. MAIA reported the first patient dosed in THIO-104 in December 2025, and screening and enrollment is underway in Europe and Asia. 

“We’re pleased to be back at ASCO, where many of the world’s leading oncology experts gather to discuss the latest advances shaping the future of cancer treatment,” said MAIA CEO Vlad Vitoc, M.D. “The level of engagement and enthusiasm surrounding our clinical programs is very encouraging, particularly as investigators continue enrolling patients in both our pivotal Phase 3 THIO-104 trial and Phase 2 THIO-101 trial expansion.”

MAIA’s ASCO 2060 poster, titled “A Phase 3 Study of Ateganosine (THIO) Sequenced with Immune Checkpoint Inhibitor (ICI) versus Standard of Care Chemotherapy in ICI-Resistant Advanced NSCLC: THIO-104 Trial in Progress,” was presented by Tomasz Jankowski, M.D., Phase 2 THIO-101 lead investigator for Poland, enrollment advisor for the pivotal Phase 3 THIO-104 clinical trial and co-author of several MAIA scientific presentations. The poster is attached to this press release and is also available on the Publications page of MAIA’s website maiabiotech.com.

“Investigators are increasingly focused on therapies that can potentially overcome resistance mechanisms and improve outcomes for patients with advanced NSCLC,” said Dr. Jankowski.

“Ateganosine has generated meaningful interest within the oncology community and may offer a promising new therapeutic option for patients who currently face very limited treatment choices.”

The ASCO Annual Meeting is the world’s largest cancer research meeting, with nearly 45,000 attendees and 166 countries represented in 2025.

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-104 Phase 3 Clinical Trial

THIO-104 is a multicenter, open-label, randomized Phase 3 clinical trial, designed to evaluate ateganosine’s telomere-targeting anti-tumor activity when followed by PD-(L)1 inhibition in patients with advanced third-line NSCLC who previously did not respond or developed resistance to treatment regimens containing checkpoint inhibitor and/or chemotherapy and have progressed. The trial has two primary objectives: (1) to assess the clinical efficacy of ateganosine compared to investigator’s choice of chemotherapy, using median Overall Survival (OS) as the primary clinical endpoint (2) to evaluate the safety and tolerability of ateganosine in sequential combination with a checkpoint inhibitor. For more information on this Phase 3 trial, please visit ClinicalTrials.gov using the identifier NCT06908304.

STAFFORD, Texas, June 01, 2026 (GLOBE NEWSWIRE) — Greenwich LifeSciences, Inc. (Nasdaq: GLSI) (the “Company”), a clinical-stage biopharmaceutical company focused on its Phase III clinical trial, FLAMINGO-01, which is evaluating Fast Track designated GLSI-100, an immunotherapy to prevent breast cancer recurrences, today presents the published abstract and poster from the ASCO Annual Meeting 2026.

The abstract is shown below and the poster being presented today can be seen and downloaded at the bottom of the Phase III clinical trial tab on the Company’s website here.

  • This is the second abstract and poster presented jointly with the Steering Committee of FLAMINGO-01 with statistically significant injection site reaction (ISR) immune response data, with subgroup analysis by the most prevalent HLA types.
  • In the non-HLA-A*02 open label arm where all patients (n=247) were treated with GLSI-100, immune responses to GP2 were measured at baseline and over time using skin tests (DTH) and ISRs.
  • An ISR reaction, erythema (redness) or induration (white hard bump), was used to assess in vivo immune responses in patients. The diameter of the reaction was assessed 48-72 hours after injection but is not reported here.
  • In this preliminary data analysis, there was a significant increase in percentage of patients experiencing an ISR reaction (for both erythema and induration) in vaccination 4, vaccination 5 or vaccination 6 compared to the baseline vaccination. There were 208 patients with both baseline vaccination and vaccination 4, 5 or 6 assessments.
  • Erythema: There was a significant increase in the percentage of patients experiencing erythema ISRs after the 4th, 5th or 6th vaccination compared to the ISRs from the 1st vaccination. In this preliminary analysis, the frequency of ISRs increased significantly from 20.2% of the patients experiencing an ISR after the first vaccination to 55.3% of the patients experiencing an ISR after the 4th, 5th or 6th vaccination (McNemar p < 0.001), representing an increase of 2.7x or 174%.
  • Induration: There was a significant increase in the percentage of patients experiencing induration ISRs after the 4th, 5th or 6th vaccination compared to the ISRs from the 1st vaccination. In this preliminary analysis, the frequency of ISRs increased significantly from 14.9% of the patients experiencing an ISR after the first vaccination to 34.6% of the patients experiencing an ISR after the 4th, 5th or 6th vaccination (McNemar p < 0.001), representing an increase of 2.3x or 132%.
  • As reported in Table 1, each HLA-A type exhibited more frequent immune reactivity with increased GLSI-100 vaccinations with frequency increasing by 60% to 280% over the frequency after the first vaccination. These results are consistent with the GP2 DTH results presented at AACR.
  • Mechanism of Action: A positive immune response is an indicator that the immune system has been activated against recurring cancer cells, potentially leading to the prevention of metastatic breast cancer. The Company previously announced that in the non-HLA-A*02 arm, a preliminary analysis of recurrence rates after the Primary Immunization Series (PIS) is completed shows an approximately 70-80% reduction in recurrence rate. Thus, the immune response data is supporting the mechanism of action that reduces recurrences and prevents metastatic breast cancer.
  • This statistically significant non-HLA-A*02 open label arm immune response data for both DTH and ISRs is trending similarly to the immune response data in the HLA-A*02 patients in the Phase IIb study and the HLA-A*02 arms of FLAMINGO-01. The study is ongoing and data collection and cleaning continue, while some patients may still be in their PIS vaccination phase, so final results may vary.

The immune response abstract and poster conclusion: The statistically significant increase in the incidence of ISR reactions over time found in this preliminary analysis of GLSI-100 treated non-HLA-A*02 patients shows that GLSI-100 treatment should not be limited to HLA-A*02 patients. Patients treated with GLSI-100 were increasingly able to mount an immune response to GP2 as evidenced in this preliminary data. Future investigations may explore the use of immune responses to assess correlation of DTH to ISRs, immunogenicity of GLSI-100 by specific HLA type, timing of boosters to sustain immunity, clinical site performance, and the discontinuation of treatment for non-responders.

CEO Snehal Patel commented, “The DTH immune response data presented at AACR and the ISR immune response data presented today together further support the mechanism of action and the combination of HLA-A*02 and non-HLA-A*02 patients in the same randomized arms, potentially improving the chances of success at the interim analysis and more than doubling the market potential for GLSI-100. This combination of patients, independent of HLA type, has already started in the US and may soon start in Europe. In addition to ASCO, the Company previously attended AACR and ESMO Breast and plans to attend BIO partnering and investor conferences in the coming months, while presenting additional FLAMINGO-01 data at any time.”

Abstract Number: LBA538 – Poster Section 23 on June 1, 2026, 1:30 – 4:30pm CT

Abstract Title: Preliminary injection site reaction immune response results from open-label arm of on-going Phase III study to evaluate the efficacy and safety of GLSI-100 (GP2 + GM-CSF) in breast cancer patients with residual disease or high-risk PCR after both neo-adjuvant and postoperative adjuvant anti-HER2 therapy, Flamingo-01

Background: This Phase III trial is a prospective, randomized, double-blinded, multi-center study (NCT05232916) in HLA-A*02 patients at approximately 140 sites in the US and Europe. A third non-randomized arm of approximately 250 non-HLA-A*02 patients is now fully enrolled and preliminary immune response data is presented below. GP2 is a biologic nine amino acid peptide of the HER2/neu protein delivered in combination with Granulocyte-Macrophage Colony Stimulating Factor (GM-CSF) that stimulates an immune response targeting HER2/neu expressing cancers, the combination known as GLSI-100.

Methods: After standard of care neoadjuvant and adjuvant therapy, 6 intradermal injections of GLSI-100 will be administered over the first 6 months and 5 subsequent boosters will be administered over the next 2.5 years. The participant duration of the trial will be 3 years treatment plus 1 additional year follow-up. Immune responses to GP2 were measured over time using delayed-type-hypersensitivity (DTH) skin tests and injection site reactions (ISRs). The patient population is defined by these key eligibility criteria: 1) HER2/neu positive and HLA, 2) Residual disease or High risk pCR (Stage III at presentation) post neo-adjuvant therapy, 3) Exclude Stage IV, and 4) Completed at least 90% of planned adjuvant trastuzumab-based therapy.

Results: All patients (n=247) were vaccinated with GLSI-100. Injection site reactions, erythema (redness) was assessed at various time points and represent an in vivo immune response in patients. The ISR orthogonal mean was measured 48-72 hours following vaccination with GLSI-100. For GP2 treated patients, there was a significant increase in the percentage of patients experiencing ISRs in the 4th, 5th or 6th vaccination compared to the ISRs from the 1st vaccination. In this preliminary analysis, the frequency of ISRs increased significantly from 20.2% of the patients experiencing an ISR after the first vaccination to 55.3% of the patients experiencing an ISR after the 4th, 5th or 6th vaccination (McNemar p < 0.001). The study is ongoing and data collection and cleaning continue so final results may vary.

Conclusions: Preliminary injection site reaction data comparing vaccination over time in GLSI-100 treated non-HLA-A*02 patients showed a significant increase in immune response. Future studies may explore the use of immune responses to assess: correlation of DTH to ISRs, immunogenicity of GLSI-100 by specific HLA type, timing of boosters to sustain immunity, clinical site performance, and the discontinuation of treatment for non-responders.

About FLAMINGO-01 Open Label Phase III Data

More than 1,300 patients have been screened with a current screen rate of approximately 800 patients per year. The 250 patient non-HLA-A*02 arm is now fully enrolled, where all patients received GLSI-100, which is 5 times more treated patients and recurrence rate data than the approximately 50 patients treated in the Phase IIb trial. The Primary Immunization Series (PIS), which includes the first 6 GLSI-100 injections over the first 6 months and is required to reach peak protection, is followed by 5 booster injections given every 6 months to prolong the immune response, thereby providing longer-term protection.

  • In the non-HLA-A*02 arm, a preliminary analysis of recurrence rates after the PIS is completed shows an approximately 70-80% reduction in recurrence rate.
  • This observation is trending similarly to the Phase IIb trial results and hazard ratio where HLA-A*02 patients were treated and where breast cancer recurrences were reduced up to 80% compared to a 20-50% reduction in recurrence rate by other approved products.
  • The immune response at baseline prior to any GLSI-100 treatment, the increasing immune response during the PIS, and the safety profile of non-HLA-A*02 patients is trending similarly to the HLA-A*02 arms of FLAMINGO-01 and to the Phase IIb study.
    • The AACR Meeting 2026 delayed-type-hypersensitivity (DTH) poster and the ASCO Meeting 2026 injection site reaction (ISR) posters can be seen and downloaded at the bottom of the Phase III clinical trial tab on the Company’s website here.
    • As shown in both posters the frequency of DTH and ISR reactions increased statistically significantly over time.
    • As reported in Table 1 of each poster, each HLA-A type exhibited more frequent immune reactivity after treatment with GLSI-100 than at baseline.
    • Baseline DTH reaction prior to any treatment suggests that GP2 may be a natural antigen and that GP2 specific T cells may exist in some patients prior to any treatment with GLSI-100. Baseline immune response to GP2 prior to any vaccination with GP2 was also observed in the Phase IIb trial and is being observed in the blinded randomized arms of FLAMINGO-01, where HLA-A*02 only patients are being vaccinated.

Analysis of the open label data from FLAMINGO-01 has been conducted in a manner that maintains the study blind. The open label recurrence rate, immune response, and safety data is based on the patients enrolled to date in FLAMINGO-01 and the data provided by the clinical sites so far, which is not completed or fully reviewed, and is thus preliminary. While comparing any preliminary FLAMINGO-01 data to the Phase IIb clinical trial data may be possible, these preliminary results are not a prediction of future results, and the results at the end of the study may differ.

About GLSI-100 Phase IIb Study

In the prospective, randomized, single-blinded, placebo-controlled, multi-center (16 sites led by MD Anderson Cancer Center) Phase IIb clinical trial of HLA-A*02 breast cancer patients, 46 HER2/neu 3+ over-expressor patients were treated with GLSI-100, and 50 placebo patients were treated with GM-CSF alone. After 5 years of follow-up, there was an 80% or greater reduction in cancer recurrences in the HER2/neu 3+ patients who were treated with GLSI-100, followed, and remained disease free over the first 6 months, which we believe is the time required to reach peak immunity and thus maximum efficacy and protection. The Phase IIb posters and results can be summarized as follows and can be seen here:

  • 80% or greater reduction in metastatic breast cancer recurrence rate over 5 years of follow-up with a peak immune response at 6 months and well-tolerated safety profile.
  • The PIS elicited a potent immune response as measured by local skin tests and immunological assays.

About FLAMINGO-01 and GLSI-100

FLAMINGO-01 (NCT05232916) is a Phase III clinical trial designed to evaluate the safety and efficacy of Fast Track designated GLSI-100 (GP2 + GM-CSF) in HER2 positive breast cancer patients who had residual disease or high-risk pathologic complete response at surgery and who have completed both neoadjuvant and postoperative adjuvant trastuzumab based treatment. The trial is led by Baylor College of Medicine and currently includes US and European clinical sites from university-based hospitals and academic and cooperative networks with plans to open up to 150 sites globally. In the double-blinded arms of the Phase III trial, approximately 500 HLA-A*02 patients are planned to be randomized to GLSI-100 or placebo, and up to 250 patients of other HLA types are planned to be treated with GLSI-100 in a third arm. The trial has been designed to detect a hazard ratio of 0.3 in invasive breast cancer-free survival, where 28 events will be required. An interim analysis for superiority and futility will be conducted when at least half of those events, 14, have occurred. This sample size provides 80% power if the annual rate of events in placebo-treated subjects is 2.4% or greater.

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%).

A copy of the Company’s poster presentation, “Opioid Use in Patients with Fibromyalgia: A Retrospective Claims Analysis,” is available under the Scientific Presentations tab on the Tonix website at https://www.tonixpharma.com/scientific-presentations/.

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 more than 10 million adults in the U.S., predominantly in 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 TONMYA® (cyclobenzaprine HCl sublingual tablets)

TONMYA (cyclobenzaprine HCl sublingual tablets) is a sublingual tablet formulation of cyclobenzaprine hydrochloride that was approved on August 15, 2025, by the FDA for the treatment of fibromyalgia in adults. TONMYA is the first new prescription medicine approved for fibromyalgia in more than 15 years. TONMYA provides rapid transmucosal absorption of cyclobenzaprine and reduced production of a long half-life active metabolite, norcyclobenzaprine, due to bypassing first-pass hepatic metabolism. TONMYA is a multifunctional agent with potent binding and antagonist activities at the 5-HT2A serotonergic, α1-adrenergic, H1-histaminergic, and M1-muscarinic receptors. TONMYA was investigated as TNX-102 SL. TNX-102 SL is also being developed to treat acute stress disorder (ASD)/acute stress reaction (ASR), and major depressive disorder (MDD).

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

Phase 1 data support TNX-1500 as a potentially first-in-class, best-in-class, third-generation anti-CD40L monoclonal antibody for the prevention of kidney transplant rejection

Phase 2 investigator-initiated study in adult kidney transplant at Massachusetts General Hospital (MGH) expected to initiate in the 2nd half of 2026 pending U.S. Food and Drug Administration (FDA) clearance of MGH’s Investigational New Drug (IND) application

BERKELEY HEIGHTS, N.J., May 27, 2026 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (“Tonix” or the “Company”), a fully integrated, commercial-stage biotechnology company, today announced the publication of a paper, “First-in-Human, Phase 1, Randomized, Double-Blind, Placebo-Controlled Study of TNX-1500, an Fc-Modified anti-CD154 Monoclonal Antibody, Evaluating the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Single-Ascending Doses in Healthy Adults,” in the peer-reviewed Journal of Clinical Immunology. TNX-1500 is an investigational, third-generation Fc-modified IgG4 anti-CD40L (also known as CD154) monoclonal antibody (mAb) in development for the prevention of organ transplant rejection and the treatment of autoimmune diseases. The manuscript can be accessed at https://pubmed.ncbi.nlm.nih.gov/42053701/.

“The CD40L is a validated target for preventing organ rejection in transplant and treating autoimmune disease, yet no anti-CD40L mAb has been approved for any indication,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “TNX-1500 is a Phase 2 ready humanized mAb engineered to improve safety and tolerability relative to first-generation anti-CD40L mAbs, while preserving the durable half-life and certain effector functions associated with the Fc or crystallizable fragment. We believe the Phase 1 results show that these design objectives were achieved in TNX-1500.”

Dr. Gregory Sullivan, M.D., Chief Medical Officer of Tonix Pharmaceuticals added, “The Phase 1 study evaluated TNX-1500’s safety, tolerability, pharmacokinetics, and pharmacodynamics. TNX-1500 was generally well tolerated, demonstrated a favorable safety profile, suppressed the primary and secondary T cell-dependent antibody responses (TDARs) to keyhole limpet hemocyanin (KLH) antigen, and showed a half-life which supports monthly intravenous dosing. We expect a Phase 2, investigator-initiated study of TNX-1500 in the prevention of kidney allograft rejection at MGH to begin in the 2nd half of 2026 pending clearance of the IND by the FDA.”

The publication reports findings from a single-center, first-in-human, Phase 1, randomized, double-blind, placebo-controlled, single-ascending dose escalation study in 26 healthy adult volunteers. Participants were enrolled across three ascending dose cohorts (3, 10, and 30 mg/kg) or placebo and received a single intravenous infusion of TNX-1500 or placebo, followed by intramuscular injections of KLH on days 2 and 29 to assess the TDAR, and monitored over a 120-day follow-up period. TNX-1500 blocked the primary T cell–dependent antibody response to KLH at all doses, blocked the secondary response at the 10 and 30 mg/kg doses, and reduced peak secondary response to KLH by ~70% relative to placebo at the 3 mg/kg dose.

TNX-1500 was generally well tolerated, with no serious adverse events, and no discontinuations due to adverse events. The only treatment-emergent adverse event (TEAE) deemed possibly related to study drug was aphthous ulcer, which occurred in 1 participant in each of the three TNX-1500 groups; all TEAEs were rated as mild and resolved in 2-10 days. No TEAEs were determined to be related to KLH administration. There were no administration or injection site reactions (one of the prespecified TEAEs of special interest). Pharmacokinetic analyses suggested approximately dose-proportional exposure across the 3 to 30 mg/kg range, with mean terminal elimination half-lives of 37.8 and 33.8 days at the 10 and 30 mg/kg dose levels, respectively. TNX-1500 at 10 and 30 mg/kg blocked the primary and secondary anti-KLH TDAR through day 120, and at 3 mg/kg reduced the peak secondary response by approximately 70% relative to placebo. Across all dose cohorts, TNX-1500 was associated with a rapid (less than one-hour post-dose) and sustained reduction in soluble CD40L (sCD154) over the 120-day study period.

About TNX-1500

TNX-1500 (Fc-modified humanized anti-CD40L mAb) is a Phase 2 ready, humanized monoclonal antibody that interacts with the CD40-ligand (CD40L), also known as CD154. TNX-1500 is being developed for the prevention of kidney transplant rejection and the treatment of autoimmune diseases. Anti-CD40L has multiple potential indications in addition to solid organ and bone marrow transplantation including autoimmune diseases. Collaborations are ongoing with MGH on allo-heart and -kidney transplantation in nonhuman primates, as well as prevention of xenograft rejection, preclinical studies, and prevention of allograft rejection in sensitized patients. The Phase 2 investigator-initiated study by MGH is expected to initiate enrollment in the 2nd half of 2026, pending FDA clearance of the IND, to evaluate TNX-1500 in five kidney transplant recipients. The study is designed to assess the safety, tolerability, and activity of TNX-1500 in preventing kidney transplant rejection while decreasing the exposure to conventional immunosuppressive drugs, which are associated with infection, cancer, cardiovascular side effects, and various metabolic derangements with long term use.

Robert LeBoyer, Senior Vice President, Equity Research Analyst, Biotechnology, Noble Capital Markets, Inc.

Refer to the full report for the price target, fundamental analysis, and rating.

Proprietary Technology Has Produced A Large Library Of Novel Antivirals. Cocrystal has developed a library of antivirals based on its proprietary technology. While clinical development has prioritized products with clear medical needs and regulatory pathways to approval, it continues to research new compounds that can be moved into development as public health needs change. After the recent outbreaks of hantavirus, Ebola, and several previously lesser-known viruses, the company tested some of these compounds and found them to be effective.

Cocrystal’s Proprietary Technology Acts Early In The Viral Lifecycle. Cocrystal drugs target enzymes essential to the viral life cycle and reproductive process. These enzymes are highly conserved across viral families and rarely mutate, allowing compounds to show broad efficacy against multiple strains. This differs from vaccines that train the immune system to recognize and kill a virus. Vaccines often target surface proteins that can mutate, rendering the vaccine ineffective.

  • 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.

About Cocrystal Pharma’s Structure-Based Drug Discovery Platform

Cocrystal is leveraging its structure‑based drug discovery platform technology to design next‑generation antiviral candidates that precisely target viral replication mechanisms. By binding to highly conserved regions of viral enzymes, the Company’s compounds aim to maintain potency against mutating strains while minimizing off‑target effects, offering potentially safer, broad‑spectrum antiviral solutions. This approach streamlines candidate identification and optimization, enabling more rapid progression of promising therapies with robust resistance and safety profiles.

The Company’s platform provides a three-dimensional structure of inhibitor complexes at near-atomic resolution, providing immediate insight to guide Structure Activity Relationships. This helps identify novel binding sites and enables a rapid turnaround of structural information through highly automated X-ray data processing and refinement. The goal of this technology is to facilitate the development of novel broad-spectrum antivirals for the treatment of acute, chronic and potentially pandemic viral diseases.

About Cocrystal Pharma, Inc.

Cocrystal Pharma, Inc. is a clinical-stage biotechnology company discovering and developing novel antiviral therapeutics that target the replication process of noroviruses, influenza viruses, coronaviruses (including SARS-CoV-2) and hepatitis C viruses. Cocrystal employs unique structure-based technologies and Nobel Prize-winning expertise to create viable antiviral drugs.

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”.

Release – Tonix Pharmaceuticals Presented Retrospective U.S. Real-World Claims Analysis Characterizing Patients with Fibromyalgia at The Professional Society for Health Economics and Outcomes Research (ISPOR) 2026 Annual Meeting

May 26, 2026 7:00am EDTDownload as PDF

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.

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 more than 10 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 TONMYA® (cyclobenzaprine HCl sublingual tablets)

TONMYA (cyclobenzaprine HCl sublingual tablets) 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.

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.
