EMA Concurrence Enables Acceleration Toward Phase 3 Initiation and Represents a Major Milestone on GeoVax’s Path to Commercialization
ATLANTA, GA – December 18, 2025 – GeoVax Labs, Inc. (Nasdaq: GOVX), a clinical-stage biotechnology company developing vaccines and immunotherapies for infectious diseases and cancer, today announced that it has received formal Scientific Advice (SA) from the European Medicines Agency (EMA) confirming regulatory alignment on the Company’s proposed pivotal Phase 3 immunobridging trial design for GEO-MVA, its Modified Vaccinia Ankara (MVA)-based vaccine candidate for the prevention of Mpox and smallpox.
The EMA’s feedback concurs with GeoVax’s proposed strategy to evaluate GEO-MVA through a single, pivotal Phase 3 immuno-bridging study versus the approved MVA vaccine, Imvanex®, and supports the Company’s plan to proceed directly into this trial without the need for additional Phase 1 or Phase 2 clinical studies. Receipt of this formal Scientific Advice represents a significant regulatory milestone and enables GeoVax to accelerate operational planning toward implementation and initiation of the Phase 3 program, currently projected to begin in the second half of 2026.
“This formal Scientific Advice from EMA represents a pivotal step forward for GEO-MVA and meaningfully de-risks our regulatory path in Europe,” said David Dodd, Chairman and Chief Executive Officer of GeoVax. “EMA’s concurrence positions GeoVax to move efficiently toward a single, registrational Phase 3 study. This is a major milestone on our path toward commercialization.”
The Scientific Advice confirms that non-inferiority immunogenicity endpoints are acceptable to support a future Marketing Authorization Application (MAA) and that GeoVax’s proposed clinical safety database is sufficient to support registration, assuming successful trial outcomes. Importantly, EMA’s feedback provides clarity and confidence across proposed clinical and quality dimensions, allowing the Company to focus on execution rather than redesign of its development strategy.
The receipt of this advice follows GeoVax’s previous announcement of favorable preliminary EMA guidance announced in June 2025 and marks the transition from regulatory alignment to regulatory execution. Together, these milestones substantially strengthen GEO-MVA’s development profile and reinforce its potential role in expanding global Mpox and smallpox vaccine supply beyond the current single-supplier paradigm.
“With formal EMA Scientific Advice now in hand, GEO-MVA moves from a conceptual regulatory pathway to a clearly defined and executable development plan,” Dodd added. “As global health authorities continue to emphasize preparedness, resilience, and diversification of vaccine supply, we believe GEO-MVA is well positioned to play an important role.”

Animal Models Show Full Protection Against Omicron Variant Despite Absence of Neutralizing Antibodies, Highlighting Critical Importance of T-cell Immunity for Next-generation COVID-19 Vaccines
ATLANTA, GA – December 18, 2025 – GeoVax Labs, Inc. (Nasdaq: GOVX), a clinical-stage biotechnology company developing multi-antigen vaccines and immunotherapies against infectious diseases and cancer, today announced the publication of a peer-reviewed article in Frontiers in Immunology titled: “Multi-antigen MVA-vectored SARS-CoV-2 vaccine, GEO-CM04S1, induces cross-protective immune responses to ancestral and Omicron variants.”
The study provides definitive preclinical evidence that GeoVax’s multi-antigen COVID-19 vaccine candidate, GEO-CM04S1, delivers full cross-variant protection, driven predominantly by robust T-cell responses, even in the absence of neutralizing antibodies.
The findings reinforce the design philosophy behind GeoVax’s MVA-based, multi-antigen platform and provide mechanistic insight that is increasingly relevant for immunocompromised individuals, who often fail to respond optimally to the first-generation COVID-19 vaccines.
Study Highlights: Multi-Antigen Breadth and T-Cell Immunity Drive Protection
The study evaluated GEO-CM04S1 in the K18-hACE2 lethal mouse model, comparing immune responses and efficacy to experimental MVA-vectored vaccine constructs expressing spike alone (S) or nucleocapsid alone (N). Key findings include:
Full protection against both ancestral B.1 and Omicron XBB.1.5: Only GEO-CM04S1 (S+N) maintained 100% survival, preventing weight loss, severe lung inflammation, and virus replication in both upper and lower airways.
Protection against XBB.1.5 occurred despite no detectable neutralizing antibodies: Neutralization assays showed zero detectable neutralizing activity against XBB.1.5 in any group – yet GEO-CM04S1-vaccinated animals were fully protected. This indicates immunity was not antibody-dependent.
CD4+ T cells were identified as the critical effector of protection: Antibody-mediated depletion studies showed:
Loss of CD4+ T cells eliminated vaccine protection, leading to high viral loads and severe lung pathology.
Depletion of CD8+ T cells or B cells had minimal impact on vaccine efficacy.
These results confirm T cell responses as the critical component of vaccine-induced immune responses capable of providing cross-variant protection.
Multi-antigen design (Spike + Nucleocapsid) outperformed spike-only vaccines: GEO-CM04S1 delivered broader and more durable immunity than spike-only MVA vaccines – especially when spike was mismatched to circulating variants.
“This publication provides significant evidence supporting the unique value of a multi-antigen designed to induce high levels of T-cell responses and validates the core design principles that differentiate our vaccine from first-generation, spike-only approaches,” said Mark Newman, PhD, Chief Scientific Officer of GeoVax.
Dr. Newman added: “These findings support the belief that the GEO-CM04S1 vaccine could be a highly relevant product for use in immunocompromised patients, because of the ability to protect through strong, multi-antigen T-cell immunity.”
“This peer-reviewed study provides a compelling scientific foundation for the ongoing clinical advancement of GEO-CM04S1,” stated David Dodd, Chairman & CEO of GeoVax. “As SARS-CoV-2 continues to evolve, it is increasingly clear that next-generation vaccines must move beyond spike-only strategies. GEO-CM04S1 demonstrates the breadth, durability, and variant-proof characteristics that global public-health leaders have been calling for.”
Dodd continued: “More than 40 million immunocompromised individuals in the U.S. alone remain underserved by existing vaccines. The results published in Frontiers in Immunology strengthen the rationale behind our multiple ongoing Phase 2 studies in immunocompromised patient populations.”
About GEO-CM04S1
GEO-CM04S1 is an MVA-vectored vaccine encoding both the Spike (S) and Nucleocapsid (N) proteins from SARS-CoV-2, designed to induce:
Strong CD4+ and CD8+ T-cell responses
Durable immunity supported by conserved N-protein recognition
Multi-antigen breadth that mitigates loss of protection as the virus mutates
GEO-CM04S1 is currently being evaluated in multiple Phase 2 clinical trials in immunocompromised patients, including individuals with hematologic cancers and chronic lymphocytic leukemia.

CDI-988 is the first oral broad-spectrum antiviral drug candidate for potential prevention of norovirus outbreaks and treatment of acute viral gastroenteritis caused by norovirus infection
There are no approved treatments or vaccines currently available for norovirus infection
BOTHELL, Wash., Dec. 18, 2025 (GLOBE NEWSWIRE) — Cocrystal Pharma, Inc. (Nasdaq: COCP) (“Cocrystal” or the “Company”) announces the approval from the Institutional Review Board (IRB) at Emory University School of Medicine to initiate a Phase 1b human challenge study with CDI-988. This study aims to evaluate CDI-988 as both a preventive and treatment for norovirus infections. Initial screening of study subjects is currently underway, with enrollment expected to begin in the first quarter of 2026. The IRB approval from Emory University School of Medicine follows Cocrystal’s prior regulatory milestones, including U.S. Food and Drug Administration (FDA) clearance of its investigational New Drug (IND) application.
CDI-988 is the first oral antiviral drug candidate developed for the prevention and treatment of norovirus acute gastroenteritis. It was specifically designed as a broad-spectrum inhibitor by targeting a highly conserved region of the viral 3CL protease of all noroviruses, including GII.4 and recently re-emerging GII.17.
The randomized, double-blind, placebo-controlled Phase 1b study will be conducted at Emory University and involve up to 40 healthy subjects ages 18-49. Participants will be screened and infected with the norovirus GII.2 (Snow Mountain Virus). The study’s primary efficacy endpoint is to assess the reduction in incidence of clinical symptoms, while the secondary efficacy endpoint focuses on the reduction in viral shedding and disease severity. The study will also assess the safety and pharmacokinetic profile of CDI-988. Additional information is available on clinicaltrials.gov.
“This approval from the Emory IRB marks a significant milestone in advancing our Phase 1b norovirus challenge study,” said Sam Lee, Ph.D., Cocrystal’s President and co-CEO. “We are very excited about collaborating with the Emory team, given their exceptional expertise in norovirus and experience in human challenge studies.
“Cocrystal’s norovirus challenge study is a critical step in addressing the global burden of norovirus outbreaks, which account for an estimated 700 million cases each year worldwide. We are committed to delivering innovative medicine for norovirus outbreaks and chronic norovirus infection among immunocompromised patients,” added Dr. Lee.
“CDI-988 may revolutionize the management of the highly contagious norovirus, which is known for quickly spreading in hospitals, nursing homes, cruise ships, schools, disaster relief sites, military settings and other semi-closed environments,” said James Martin, CFO and co-CEO. “Used as a prophylaxis, oral CDI-988 could offer a potential solution and add a new layer of defense.”
CDI-988 was designed with Cocrystal’s proprietary structure-based drug discovery platform technology. In August 2025 Cocrystal announced favorable Phase 1 safety and tolerability data from all CDI-988 dose cohorts including the highest dose of 1200 mg. In September 2025 the Company received a Study May Proceed Letter from the FDA for the Phase 1b challenge study.

Milestone Advances Clinical Readiness and Reinforces Urgent U.S. Need for Domestic MVA Vaccine Capacity
ATLANTA, GA – December 17, 2025 – GeoVax Labs, Inc. (Nasdaq: GOVX), a clinical-stage biotechnology company developing vaccines and immunotherapies against infectious diseases and cancer, today announced the successful completion of fill-finish for the initial clinical batch of GEO-MVA, its next-generation Mpox/smallpox vaccine. The product has now entered final release evaluation, the concluding quality-control and compliance process required before shipment for clinical use, positioning the Company for Phase 3 immunobridging trial start-up activities in Q1 2026.
Clinical and Regulatory Milestone
Fill-finish – the sterile, cGMP-regulated process of filling, sealing, and packaging vaccine vials – marks the last manufacturing step before a vaccine may enter clinical study supply channels. With fill-finish complete and GEO-MVA now undergoing final release evaluation, GeoVax has moved into the final pre-clinical-deployment phase of its EMA-aligned clinical program.
In June 2025, the European Medicines Agency (EMA) Scientific Advice confirmed that a single Phase 3 immunobridging study demonstrating immune comparability to the approved MVA vaccine, Imvanex®, would be sufficient to evaluate GEO-MVA’s efficacy. This provides a clear, accelerated regulatory path to licensure.
Strengthening U.S. and Global Pandemic Preparedness
This milestone coincides with increasing Mpox activity globally – including expanding Clade I outbreaks in Africa and emerging cases in the United States – exposing vulnerabilities associated with global dependence on a sole foreign MVA vaccine supplier. GEO-MVA is designed to expand supply, diversify sources, and strengthen biodefense infrastructure.
David Dodd, Chairman & CEO of GeoVax, commented: “Completion of fill-finish for GEO-MVA and progression into final release evaluation represent critical steps toward Phase 3 initiation and a pivotal advancement in our mission to support U.S. and global health security. America cannot remain dependent on a single foreign manufacturer for MVA-based biodefense vaccines. GEO-MVA provides a clear path toward a diversified and domestically controlled second-source supply – an essential component of modern pandemic preparedness. This milestone also underscores the strong operational progress we are delivering for our shareholders and partners.”
About GEO-MVA
GEO-MVA is a Modified Vaccinia Ankara (MVA)-based Mpox/smallpox vaccine designed to expand global vaccine availability at a time of constrained stockpiles and growing demand for resilient, scalable, and geographically diversified manufacturing capacity.

Tonix Announced Acquisition of A Non-Opioid Pain Reliever. Tonix continues to build its neurological pain pipeline with the licensing of a Sigma-1 receptor antagonist for development in neuropathic pain relief. Published studies on the Sigma-1 receptor’s mechanism of action have shown activity in pain and several neurological diseases. We see this as an extension of the company’s product line in neurology, including products for fibromyalgia/pain, acute stress disorder, major depressive disorder, and migraine headache.
TNX-4900 Is Highly Selective For The Sigma-1 Receptor. The new molecule, known as TNX-4900, is a small molecule developed to be highly selective for the Sigma-1 receptor, avoiding the Sigma-2 and other Sigma receptor-family members. It has been tested in multiple models of pain and selected for its efficacy and safety profile. TNX-4900 has also shown ability to cross the blood-brain barrier, with favorable adsorption, distribution, metabolism and elimination (ADME) properties.

After several challenging years marked by higher interest rates, tighter capital markets, and depressed valuations, signs are emerging that the biotech sector may be on the cusp of a meaningful turnaround. One of the clearest indicators is the renewed pickup in mergers and acquisitions activity across biotech and pharmaceutical companies. Historically, periods of rising M&A have often preceded broader recoveries in biotech equities, particularly among small- and mid-cap names that have been trading at discounted valuations.
Large pharmaceutical companies are once again stepping up as active acquirers. Many face looming patent expirations that threaten billions of dollars in revenue over the next several years, creating urgency to replenish drug pipelines. Rather than relying solely on in-house research and development, big pharma is increasingly turning to acquisitions and strategic partnerships with innovative biotech firms that already have promising assets in development. This dynamic disproportionately benefits smaller biotech companies, which often lack the capital to fully commercialize therapies on their own but possess highly valuable intellectual property.
The macroeconomic backdrop is also becoming more supportive. Expectations around interest rate cuts play a critical role in driving this renewed activity. Biotech companies are capital-intensive by nature, frequently operating for years without meaningful revenue while funding clinical trials and regulatory processes. When interest rates are high, the cost of capital rises, making financing more difficult and suppressing valuations. As rates begin to fall—or even as markets anticipate easing—capital becomes cheaper and more accessible, enabling both buyers and sellers to transact more confidently.
Lower interest rates also have a powerful effect on biotech valuations. Because many biotech companies derive much of their value from future potential cash flows rather than current earnings, they are particularly sensitive to discount rates used in valuation models. When rates decline, the present value of future earnings increases, supporting higher valuations across the sector. This dynamic can help reverse the multiple compression biotech stocks experienced during the tightening cycle.
In addition, rate cuts tend to shift investor behavior toward a more “risk-on” environment. As yields on safer assets like bonds decline, investors are more inclined to seek growth opportunities in sectors such as biotech, where innovation and breakthrough therapies can drive outsized returns. Rising equity prices and improved sentiment, in turn, make biotech companies more attractive acquisition targets, reinforcing the M&A cycle.
For small-cap biotech investors, this combination of increased deal activity and improving macro conditions is particularly significant. M&A announcements often come with substantial acquisition premiums, providing immediate upside for shareholders and helping reprice comparable companies across the sector. Even firms that are not direct acquisition targets can benefit as investors reassess the strategic value of underappreciated pipelines and platforms.
While risks remain and selectivity is still critical, the resurgence of biotech M&A alongside a more favorable interest rate environment suggests that the sector’s prolonged downturn may be nearing its end. If rate cuts materialize and deal momentum continues, biotech—especially at the small-cap level—could be positioned for a sustained recovery rather than just a short-term bounce.

Non-opioid analgesic shows efficacy in several animal pain models, including diabetic and chemotherapy-induced neuropathic pain
Compelling safety and pharmacokinetic profiles in animals support IND-enabling studies
CHATHAM, N.J., Dec. 16, 2025 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (“Tonix” or the “Company”), a fully-integrated commercial biotechnology company, today announced licensing exclusive worldwide rights to TNX-4900 (formerly known as PW507), a highly selective small-molecule Sigma-1 receptor (S1R) antagonist with demonstrated analgesic activity in multiple models of neuropathic pain.
“Sigma-1 receptor antagonism has generated considerable scientific interest as a promising class of non-opioid, non-addictive analgesics,” said Seth Lederman, M.D., President and Chief Executive Officer of Tonix Pharmaceuticals. “With our extensive experience studying and developing an FDA approved non-opioid analgesic we are well-positioned to oversee this new development program. We believe TNX-4900 has the potential to be best-in-class.”
Dr. Youyi Peng, co-inventor of TNX-4900, formerly a Senior Bioinformatics Specialist at the Rutgers Cancer Institute of New Jersey and now a consultant to Tonix, added, “We used computer-aided and AI-driven approaches to design this new class of selective Sigma-1 receptor antagonists. TNX-4900 showed robust analgesic efficacy in multiple pain models and an encouraging safety profile, supporting its potential as a new non-opioid approach to treating neuropathic pain.”
TNX-4900 was created from a structure-based drug design program led by Dr. Youyi Peng and Dr. William Welsh at Rutgers University that produced a series of potent and selective triazole-based S1R antagonists. The compound binds the human Sigma-1 receptor with nanomolar affinity (Ki = 7.5 nM), demonstrates > 100-fold selectivity over the Sigma-2 receptor, and exhibits high blood-brain barrier penetration and favorable adsorption, distribution, metabolism and elimination (ADME) properties, including oral bioavailability of approximately 28%.
“Our foundational research into TNX-4900 represents an important step toward developing non-opioid solutions for chronic pain. We are pleased to see this innovation progress toward potential clinical application, which could address a critical need for safer pain management options,” said Dr. William Welsh, Distinguished Professor in the Department of Pharmacology at Rutgers Robert Wood Johnson Medical School (RWJMS).
In preclinical models of diabetic and chemotherapy-induced neuropathic pain, TNX-4900 produced significant and durable reductions in pain behaviors after both acute and chronic dosing without evidence of tolerance or motor impairment. Tonix plans to advance TNX-4900 through expanded pharmacokinetic, formulation, and safety studies to support IND-enabling development.

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.

DSMB Ends Comparator Arm; Trial Proceeds Exclusively With GEO-CM04S1 Following mRNA Vaccine’s Failure to Meet Primary Endpoint
Phase 2 Data Reinforce GEO-CM04S1 as an Important Next-generation Vaccine Candidate for the 40 Million U.S. and 400 Million Global Immunocompromised Patients Underserved by First-generation COVID-19 Vaccines
ATLANTA, GA – December 15, 2025 – GeoVax Labs, Inc. (Nasdaq: GOVX), a clinical-stage biotechnology company developing multi-antigen vaccines and immunotherapies, today announced the publication of interim Phase 2 clinical data on its next-generation COVID-19 vaccine in patients with chronic lymphocytic leukemia (CLL).
The Research Letter in the British Journal of Haematology reports that GEO-CM04S1 met the study’s primary immunologic endpoint, generating significantly stronger and more durable SARS-CoV-2–specific T-cell responses than BNT162b2 (Pfizer-BioNTech) in patients with chronic lymphocytic leukemia (CLL) – a population known for poor vaccine responsiveness.
Importantly, following interim analysis, the trial’s Data and Safety Monitoring Board (DSMB) ruled to discontinue the randomized, double-blind comparator arm after the mRNA vaccine failed to meet the predefined primary immunogenicity endpoint. Enrollment is now proceeding exclusively in a single-arm cohort receiving GEO-CM04S1, as previously described in GeoVax’s clinical update at the European Hematology Association (EHA) 2025 Conference.
GEO-CM04S1’s superior performance in enhancing cellular immune response against SARS-CoV-2 in individuals with CLL, a patient population that generally responds sub optimally to vaccines designed to induce humoral (antibody) responses, underscores its potential to fill a protection gap for profoundly immunocompromised patients. More than 40 million adults in the U.S. and 400 million globally have some degree of compromised immunity, many of whom fail to mount meaningful responses to currently authorized COVID-19 vaccines. GEO-CM04S1 is specifically designed to address this gap through its dual-antigen (Spike + Nucleocapsid), MVA-based platform, which promotes robust, durable T-cell responses that are less impacted by immune dysfunction and viral variation.
Phase 2 Study Overview (NCT05672355)
CLL patients previously vaccinated with mRNA vaccines
31 enrolled; 27 evaluable for primary analysis
Primary endpoint: ≥3-fold rise in antigen-specific IFN-γ–secreting T cells at Day 56
40% of GEO-CM04S1 recipients met the primary endpoint vs. 14.3% for BNT162b2
Higher Spike-specific IFN-γ responses at Days 28, 56, and 84
2. Durable activation of Nucleocapsid-specific T cells
~10-fold higher N-specific CD4 T-cell activation vs. BNT162b2
Responses maintained through Day 180
3. Broader immune engagement in spite of CLL-associated humoral defects
GEO-CM04S1 generated sustained N-IgG and a correlation between N-specific antibodies and T-cell activation
mRNA vaccination produced higher early RBD-IgG titers but limited cellular immunity
Kelly T. McKee, MD, MPH, Chief Medical Officer, stated: “These results demonstrate GEO-CM04S1’s ability to address the immune limitations of CLL patients by inducing strong, durable T-cell responses to both spike and nucleocapsid proteins of SARS-CoV-2. The DSMB’s decision to discontinue the comparator arm further validates the vaccine’s clinical relevance for immunocompromised individuals.”
David Dodd, Chairman & CEO, added: “With more than 40 million immunocompromised Americans, many of whom lack durable protection from first-generation vaccines, GEO-CM04S1 represents a purpose-built solution for high-risk patients. This peer-reviewed publication strengthens our regulatory and partnering strategy as we advance toward potential commercialization.”
Medical and Commercial Significance
The findings published in BJH, combined with the DSMB’s action, reinforce the value of the differentiated profile of GEO-CM04S1 across multiple dimensions:
Critical unmet need: Immunocompromised individuals remain vulnerable and, in many cases, sub optimally protected from the threat of SARS-CoV-2.
Multi-antigen design: GEO-CM04S1’s dual-antigen design stimulates immune responses that appear to be more durable and variant-resilient than single-antigen mRNA approaches.
These segments represent a $30B+ annual potential commercial market.
About GEO-CM04S1
GEO-CM04S1 is a dual-antigen MVA-vectored COVID-19 vaccine being evaluated in multiple Phase 2 trials, including a primary vaccination for immunocompromised individuals, and a booster vaccination for CLL patients.
The vaccine has generated robust immune responses in difficult-to-vaccinate populations including CAR-T and stem-cell transplant recipients, who typically fail to respond well to first-generation vaccines.
About GeoVax
GeoVax Labs, Inc. is a clinical-stage biotechnology company developing novel vaccines against infectious diseases and therapies for solid tumor cancers. The Company’s lead clinical program is GEO-CM04S1, a next-generation COVID-19 vaccine currently in three Phase 2 clinical trials, being evaluated as (1) a primary vaccine for immunocompromised patients such as those suffering from hematologic cancers and other patient populations for whom the current authorized COVID-19 vaccines are insufficient, (2) a booster vaccine in patients with chronic lymphocytic leukemia (CLL) and (3) a more robust, durable COVID-19 booster among healthy patients who previously received the mRNA vaccines. In oncology the lead clinical program is evaluating a novel oncolytic solid tumor gene-directed therapy, Gedeptin®, having recently completed a multicenter Phase 1/2 clinical trial for advanced head and neck cancers.

Actual results may differ materially from those included in these statements due to a variety of factors, including whether: GeoVax is able to obtain acceptable results from ongoing or future clinical trials of its investigational products, GeoVax’s immuno-oncology products and preventative vaccines can provoke the desired responses, and those products or vaccines can be used effectively, GeoVax’s viral vector technology adequately amplifies immune responses to cancer antigens, GeoVax can develop and manufacture its immuno-oncology products and preventative vaccines with the desired characteristics in a timely manner, GeoVax’s immuno-oncology products and preventative vaccines will be safe for human use, GeoVax’s vaccines will effectively prevent targeted infections in humans, GeoVax’s immuno-oncology products and preventative vaccines will receive regulatory approvals necessary to be licensed and marketed, GeoVax raises required capital to complete development, there is development of competitive products that may be more effective or easier to use than GeoVax’s products, GeoVax will be able to enter into favorable manufacturing and distribution agreements, and other factors, over which GeoVax has no control.
Further information on our risk factors is contained in our periodic reports on Form 10-Q and Form 10-K that we have filed and will file with the SEC. Any forward-looking statement made by us herein speaks only as of the date on which it is made. Factors or events that could cause our actual results to differ may emerge from time to time, and it is not possible for us to predict all of them. We undertake no obligation to publicly update any forward-looking statement, whether as a result of new information, future developments or otherwise, except as may be required by law.
