Phase 1/2 trial confirms safety with repeated dosing supporting further development in early-stage disease and combination treatment settings
ATLANTA, GA – December 8, 2025 – GeoVax Labs, Inc. (Nasdaq: GOVX), a clinical-stage biotechnology company developing novel immunotherapies and vaccines for solid tumor cancers and infectious diseases, today announced the publication of a peer-reviewed article in JCO Oncology Advances, the American Society of Clinical Oncology’s (ASCO) open-access journal.
The manuscript, titled “A Phase 1/2 Study of Intratumoral Ad/PNP (Gedeptin) with Fludarabine Phosphate in Subjects with Recurrent Head and Neck Cancer”, reports findings from a multi-center clinical trial evaluating repeated cycles of Gedeptin®, a gene-directed enzyme prodrug therapy (GDEPT), administered via intratumoral injection followed by systemic fludarabine.
Study Overview: Evaluating Repeated Dosing in a Highly Refractory Population
The Phase 1/2 trial enrolled patients with recurrent head and neck cancers who had exhausted all standard treatment options and had undergone a median of four prior lines of systemic therapy. Patients received therapy on a 28 day schedule, each consisting of intratumoral Gedeptin injections followed by intravenous fludarabine.
Key results from the publication include:
Acceptable safety profile with no new safety signals: Serious adverse events were uncommon and generally unrelated to treatment. No deaths were attributed to study therapy.
Clinical evidence of disease stability: Three of eight patients (37.5%) in this cohort of patients with end-stage disease achieved stable disease.
Successful tumor transduction and PNP transgene expression: Tumor biopsies confirmed uptake and expression of the therapeutic E. coli PNP transgene in all evaluable patients, supporting the mechanistic foundation of the Gedeptin platform.
Study results suggest that earlier intervention, higher vector dosing, improved tumor transduction, or combination therapy (e.g., with immune checkpoint inhibitors) may further increase efficacy. Preclinical findings cited in the manuscript show that Gedeptin-mediated tumor destruction may sensitize tumors to checkpoint inhibitors, offering a promising path forward.
J. Marc Pipas, MD, Executive Medical Director, Oncology of GeoVax, stated: “This publication reinforces the strong scientific rationale underpinning the Gedeptin platform. Even in a highly refractory patient population with extensive prior treatment, repeated intratumoral dosing of Gedeptin demonstrated a favorable safety profile and evidence of disease stability. Importantly, correlative analyses confirmed robust tumor transduction and PNP expression, a critical mechanistic milestone for gene-directed enzyme prodrug therapy.”
Kelly T. McKee, MD, MPH, Chief Medical Officer of GeoVax, added: “These results support the continued development of Gedeptin in settings where tumor burden is lower, patients are less heavily pretreated, or where combination strategies, particularly with immune checkpoint inhibitors, may amplify therapeutic benefit. This aligns with our strategy to advance Gedeptin into neoadjuvant studies for surgically resectable recurrent head and neck cancers.”
David Dodd, Chairman & CEO of GeoVax, stated: “The publication in the ASCO journal underscores both the scientific significance of this trial and the need for new approaches to treat recurrent head and neck cancers. Gedeptin’s targeted mechanism, combined with its repeat-dosing feasibility, offers a promising therapeutic option for patients. We look forward to expanding development into earlier disease settings and into rational combination regimens.”
About the Gedeptin® Platform
Gedeptin is a non-replicating adenoviral vector delivering the E. coli purine nucleoside phosphorylase (PNP) gene directly into tumor tissue. Following intratumoral injection, patients receive systemic fludarabine, which is converted in PNP-expressing tumor cells into a potent cytotoxic metabolite (2-fluoroadenine, F-Ade).
Key characteristics include:
Tumor-agnostic mechanism of action, driven by localized intratumoral activation of fludarabine into the potent cytotoxin F-Ade, enabling activity independent of tumor histology or proliferation rate.
Strong bystander effect, in which the activated F-Ade diffuses to neighboring cancer cells – allowing Gedeptin to kill tumor cells even when only a small fraction is directly transduced.
Immune-sensitizing properties that enhance tumor antigen visibility and may improve responses to immune checkpoint inhibitors.
Favorable safety profile, demonstrated across early Phase 1 and Phase 1/2 studies and supported by consistent tolerability in heavily pretreated solid tumor patients.
Gedeptin is now progressing toward combination-therapy in a neoadjuvant clinical program. Building on robust preclinical data showing that Gedeptin enhances tumor sensitivity to immune checkpoint blockade, GeoVax is advancing plans to evaluate Gedeptin with agents such as pembrolizumab aiming to strengthen antitumor immune activation.

STAFFORD, Texas, Dec. 08, 2025 (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 GLSI-100, an immunotherapy to prevent breast cancer recurrences, today announced the completion of enrollment in the open label non-HLA-A*02 arm of FLAMINGO-01.
In the double-blinded arms of the Phase III trial, approximately 500 HLA-A*02 patients are currently planned to be randomized to GLSI-100 or placebo, and up to 250 patients of other HLA types (non-HLA-A*02) are planned to be treated with GLSI-100 in a third open label arm. The non-HLA-A*02 patients do not have the HLA-A*02 allele from either parent and represent about 55% of the patient population in FLAMINGO-01.
FLAMINGO-01 has achieved a major milestone by completing enrollment in the 250 patient open label non-HLA-A*02 arm of the Phase III trial, which is a result of the high screen rate and ensuing enrollment rate. The Company is continuing its review of the most recent data of this arm, including recurrence rates, which can be updated and/or published at any time.
The Company stopped enrolling in this arm earlier this year and is now approaching regulatory agencies to seek approval to continue enrollment of new non-HLA-A*02 patients in a randomized manner with a control arm. The Company has continued to screen a large number of these patients so that rapid enrollment of these screened patients can commence if regulatory approval is received.
The Company previously reported promising observations earlier this year showing that the immune response at baseline prior to any GLSI-100 treatment, the increasing immune response during the primary immunization series, 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, where breast cancer recurrences were reduced up to 80% or more and no metastatic breast cancer recurrences were reported. A preliminary analysis suggests that these promising trends are continuing.
CEO Snehal Patel commented, “As we continue to analyze the immune response, safety, and recurrence rate data of the 250 patient non-HLA-A*02 data set, it is important to remember that all 250 patients received GLSI-100, which is 5 times more than the approximately 50 patients treated in the Phase IIb trial. We can compare the open label recurrence rate data of these 250 treated patients to the expected historical recurrence rate for this population, which is well known and recently reported, to the HLA-A*02 arms of FLAMINGO-01, and to the Phase IIb study. In addition, we may be able to compare the recurrence rate during the first 6 months of vaccination, also called the primary immunization series or PIS, to the recurrence rate after the PIS is completed and after peak immunity is achieved. We look forward to providing updates on this analysis at any time, including publications at conferences as we have previously done for the Phase IIb trial from 2020-2022.”
Mr. Patel added, “The use of GLSI-100 in the non-HLA-A*02 patient population is an invention by the Company, and the Company believes that any patent claims related to this invention are not subject to any license, royalties, or milestone payments. These patent claims should complement other patent claims that the Company has recently filed to potentially extend patent protection of GLSI-100 beyond 2040. The Company believes that this patient population could double the number of US and European patients eligible for GLSI-100 treatment to approximately 88,000 new patients per year with a market potential using the drug prices per year of Kadcyla or Enhertu in the range of $8-10 billion per year.”
Additional updates:
The non-HLA-A*02 types that are most commonly being enrolled in FLAMINGO-01 continue to be HLA-A*03, HLA-A*24, HLA-A*01, HLA-A*11, HLA-A*68, HLA-A*29, HLA-A*30, HLA-A*23, and HLA-A*33.
The enrollment of HLA-A*02 patients in the 500 patient randomized arms continues, unaffected by the end of enrollment in the non-HLA-A*02 arm, while the Company also seeks to increase the size of these HLA-A*02 arms such that enrollment is not stopped prior to any interim analyses.
Enhertu (trastuzumab Deruxtecan [T-DXd]) treated patients continue to be eligible for enrollment in FLAMINGO-01. The Company believes that GLSI-100 will synergize with any trastuzumab based treatment in the neoadjuvant or adjuvant settings, including Enhertu.
About FLAMINGO-01 and GLSI-100
FLAMINGO-01 (NCT05232916) is a Phase III clinical trial designed to evaluate the safety and efficacy of 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.

Mirum Pharmaceuticals (NASDAQ: MIRM) has announced a definitive agreement to acquire privately held Bluejay Therapeutics in a transformative deal that expands Mirum’s leadership in rare liver diseases and adds a high-potential late-stage asset to its growing pipeline. The acquisition, valued at $620 million upfront in cash and stock — plus up to $200 million in milestone payments — brings worldwide rights to brelovitug, a fully human monoclonal antibody currently in Phase 3 development for chronic hepatitis delta virus (HDV).
For Mirum, a company already recognized for developing and commercializing rare disease therapies—including LIVMARLI, CHOLBAM and CTEXLI—the deal aligns directly with its strategic focus: advancing life-changing medicines for overlooked patient populations. HDV, the most severe form of viral hepatitis, represents a large, high unmet-need market with no FDA-approved treatments, affecting more than 230,000 people across the U.S. and Europe.
Brelovitug has already gained international attention. The therapy holds FDA Breakthrough Therapy designation and the European Medicines Agency’s PRIME and Orphan designations. In Phase 2 trials, it demonstrated strong antiviral activity and a 100% HDV RNA response rate, along with improvements in liver enzyme levels. Its safety profile has been favorable, with the most notable adverse event being injection-site reactions.
The drug is currently being evaluated in the global, registrational AZURE Phase 3 program, which is enrolling patients worldwide. Top-line results are expected in the second half of 2026, with a potential BLA submission and commercial launch in 2027. If approved, brelovitug could become the first widely available treatment for chronic HDV.
Mirum CEO Chris Peetz emphasized that the acquisition fits squarely within Mirum’s mission and capabilities. “Brelovitug in HDV leverages our deep expertise in rare liver disease and builds on the relationships we’ve established with key providers through the volixibat and LIVMARLI programs,” he said. Bluejay’s founder and CEO, Keting Chu, echoed that sentiment, noting that Mirum’s rare disease specialization makes it “the right company to carry this program forward globally.”
The acquisition will be funded through a combination of cash, Mirum common stock, and a concurrent $200 million private placement with healthcare investors. Proceeds from the placement will support both clinical development and future commercial activities. The deal not only adds a late-stage asset to Mirum’s portfolio but also positions the company for four potential registrational readouts within the next 18 months—an unusually rich pipeline for a rare-disease-focused biotech.
Implications for the Biotech Landscape
The acquisition underscores a broader trend in the biotechnology sector: rare disease companies with commercial infrastructure are increasingly seeking late-stage assets to accelerate revenue growth and expand global presence. For small and mid-cap biopharma firms, especially those with single or early-stage assets, partnerships or acquisitions by specialized players like Mirum remain attractive pathways to scale.
Bluejay itself represents a textbook example of a high-quality private biotech that rapidly advanced a novel therapy—from development candidate to global Phase 3 program in four years—making it an appealing target in a competitive rare-disease market.
Pending regulatory approvals, the transaction is expected to close in the first quarter of 2026. If successful, brelovitug could mark one of the most important therapeutic advancements in liver disease in decades—and a major milestone in Mirum’s evolution into a global leader in rare hepatology.
STAFFORD, Texas, Dec. 03, 2025 (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 GLSI-100, an immunotherapy to prevent breast cancer recurrences, today provided the following global update on FLAMINGO-01.
Flamingo-01 Progress to Date
The Company has achieved a major milestone by screening over 1,000 patients in Flamingo-01, continuing its screening rate of approximately 150 patients per quarter or the equivalent of 600 patients per year in approximately 40 US sites and 100 EU sites for a total of 140 active sites. The Company is considering a strategy to continue enrolling in both the HLA-A*02 and non-HLA-A*02 arms until interim analyses are conducted and the appropriate size of each arm can be further assessed.
CEO Snehal Patel commented, “Reaching 1,000 screened patients confirms that the interest from doctors and patients is high. The clinical site start-up activities in Europe in 2025 have further increased the momentum in the study. We are also receiving interest from other countries to join FLAMINGO-01, driven by patient interest. The high screening rate will give the Company many options, including the opportunity to continue enrollment through multiple interim analyses, the potential to realize higher enrollment rates and event rates, and the potential to maximize indications by analyzing efficacy across multiple HLA types in larger patient populations.”

Bridging the Compensation, Culture, and Compliance Gaps for Value Realization in 2025
The Healthcare and Life Sciences (HCLS) sector continues to be a powerhouse for global Mergers & Acquisitions (M&A) activity, driven by digitalization, specialized therapeutics, and the imperative for integrated care models. When European entities acquire US counterparts, the primary risk to deal value shifts from financial modeling to human capital integration. In 2025, transatlantic HCLS deals face an unprecedented trifecta of challenges: navigating the US’s competitive, burnout-driven talent market; identifying and realizing true operational synergies; and bridging the fundamental divide between US and EU compensation and benefits philosophies. Successfully integrating talent across these vastly different labor ecosystems is now the defining feature of deal success.
The Fierce Pursuit of Specialized US HCLS Talent
The US HCLS talent market in 2025 is defined by scarcity, rising costs, and high turnover – especially for highly specialized roles in advanced therapeutics, bioinformatics, and AI-driven diagnostics. Would-be European acquirers of US HCLS companies must move beyond reactive hiring to adopt future-ready strategies:
Skills-First & AI Operationalization: The industry is moving toward skills-based hiring, particularly for critical roles that drive transformation and innovation (e.g., Gene Editing, GenAI). While AI is being widely operationalized to streamline administrative burdens (scheduling, screening, drafting job descriptions), it has yet to be proven as a strategic tool for high-level talent strategy or predicting cultural fit. Smart integration plans, therefore, should prioritize leveraging AI to accelerate efficiency while reserving human expertise for assessment and strategic sourcing.
EVP and Retention over Recruitment: High turnover, burnout, and the rise of non-traditional healthcare employers (tech, consulting) have made retention the top priority. The Employer Value Proposition (EVP) must be hyper-personalized and focused on fostering Equity, Inclusion, and Belonging (EIB), shifting the focus from simply who is hired to who stays, grows, and thrives. Post-merger, US employees often prioritize clear career pathways, flexibility, and supportive management when choosing to remain with the combined entity.
Proactive Pipelining: Due to the shrinking talent pool, organizations might rely heavily on talent pipelining and targeted outbound campaigns, establishing relationships with specialized talent before roles are officially posted. Integration teams could leverage the European target’s existing academic partnerships or regional centers of excellence to feed into the US-side pipeline for highly technical roles.
Operational Synergies: A Shift to Scope and Capability
Transatlantic HCLS M&A is increasingly dominated by scope deals—acquisitions focused on new technology, market access, or specific clinical capabilities, rather than simple scale. Synergy capture in these deals is more complex and requires aggressive planning that goes beyond traditional cost-cutting:
Revenue Synergies in R&D and Market Access: The most significant value tends to be found in revenue synergies, such as combining the European acquirer’s innovative R&D capabilities and global footprint with the US target’s vast commercialization strength and specialized talent access. Due diligence must build complex synergy models to validate these revenue forecasts, which are inherently more difficult to predict than cost savings.
Consolidating Back-Office Functions: Classic operational synergies still apply, particularly in consolidating redundant non-patient-facing functions. Examples include streamlining financial administration, IT infrastructure, and back-office services like Revenue Cycle Management (RCM) or billing. This consolidation can lead to immediate cost savings and process standardization but must be executed early in the integration lifecycle to realize value.
Cultural Alignment as a Synergist: Synergy capture is often derailed by poor cultural alignment. Integration planning should prioritize blending cultural elements early on. For a European company acquiring a US firm, navigating different approaches to hierarchy, risk tolerance, and work-life balance will be crucial to retaining the very R&D or specialized operational talent the deal was meant to secure.
Navigating the Transatlantic Compensation & Benefits Chasm
The starkest challenge in harmonizing US and EU operations lies in aligning compensation, benefits, and labor practices, which reflect fundamentally different societal models:
The Salary and Contribution Divide: US salaries are generally higher, often dramatically so for specialized roles (e.g., mid-level tech salaries can show a 30–50% gap). However, the underlying employer cost structure differs significantly. US employers bear steep costs for private, market-driven healthcare ($8,000 to $16,000+ per employee annually), while EU employers bear heavy social charges and payroll contributions that fund state-backed universal healthcare and pensions. Integration teams should employ dual benchmarks, modeling both equal salaries (for equity assessment) and market-specific total compensation (for budget control).
Mandated Benefits and Labor Law: Europe offers generous, often legally mandated benefits, including a minimum of 20+ paid vacation days, comprehensive parental leave, and stricter labor protections regarding notice periods and dismissal costs. In contrast, US benefits are a competitive tool, varying widely by state and company size. Attempting to impose a US-centric “low vacation, high private insurance” model on EU operations could result in catastrophic talent loss and non-compliance with local labor law.
Compliance Complexity: The US operates under a fragmented legal structure of both federal (e.g., ACA and COBRA and state-specific laws (sick leave, minimum wage, worker classification), whereas the EU operates under centralized directives, but implementation varies across 27 Member States (e.g., Spain and Portugal requiring 14-month salaries). HR teams must deploy local expertise to avoid compliance pitfalls, particularly around worker classification and termination processes.
In conclusion, successful transatlantic HCLS M&A requires HR integration teams to treat human capital as a strategic asset, not just a line item. Value is realized when the best of both labor ecosystems is preserved, harmonizing compensation and benefits while leveraging the combined entity’s specialized talent pools through proactive, skills-focused strategies.
In the next installment of our Europe-US Cross-Border HCLS M&A series, we move from people to data, tackling the ultimate transatlantic compliance hurdle: the clash between GDPR and HIPAA. Learn how European acquirers can avoid major fines and deal breaks by meticulously auditing and integrating data governance across two radically different legal frameworks.

Tonix plans to initiate potential pivotal Phase 2 HORIZON study of TNX-102 SL in adults with major depressive disorder in mid-2026
More than 21 million US adults experience a major depressive episode each year
CHATHAM, N.J., Nov. 24, 2025 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (“Tonix” or the “Company”), a fully-integrated commercial biotechnology company, today announced the U.S. Food and Drug Administration (FDA) has cleared the Investigational New Drug (IND) application to support clinical development of TNX-102 SL (cyclobenzaprine HCl sublingual tablets) 5.6 mg for the treatment of major depressive disorder (MDD) in adults.
“There is a clear need for innovative therapies that address depression,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “We believe TNX-102 SL offers a promising approach for individuals suffering from MDD. The unique pharmacological profile of TNX-102 SL is designed to target the disruptive sleep which is often associated with depression. Prior studies of TNX-102 SL in fibromyalgia and post-traumatic stress disorder (PTSD) showed promising signals for improvement of depressive symptoms on the Beck Depression Inventory-II and the Montgomery-Asberg Depression Rating Scale (MADRS), respectively. We are excited to advance TNX-102 SL and look forward to evaluating its potential as a new treatment option for those affected by depression.”
The IND clearance enables Tonix to proceed with the potentially pivotal Phase 2 HORIZON study, a 6-week, randomized, double-blind, placebo-controlled study of TNX-102 SL as a first-line monotherapy in adults with MDD. About 360 patients will be enrolled at approximately 30 U.S. sites. Eligible participants are 18 years or older and currently experiencing a moderate to severe major depressive episode. The study will compare TNX-102 SL 5.6 mg, taken sublingually at bedtime to placebo, with the primary endpoint being the MADRS total score change from baseline at Week 6. Secondary endpoints include global impression scores, anxiety ratings, and measures of sleep disturbance. Tonix plans to initiate enrollment of the study in mid-year 2026.
“TNX-102 SL is designed to target the disturbed sleep of depression, which is a novel mechanism of action,” said Gregory Sullivan, M.D., Chief Medical Officer of Tonix Pharmaceuticals. “TNX-102 SL has been generally well tolerated in registrational studies of fibromyalgia patients. In the fibromyalgia studies, TNX-102 SL treatment was associated with a low incidence of side effects common with traditional antidepressants like weight gain, blood pressure changes, sexual dysfunction and cognitive issues.”
About Major Depressive Disorder Major Depressive Disorder (MDD) is a prevalent and serious psychiatric illness that affects adults of all ages, races, and backgrounds. It is characterized by persistent feelings of sadness or loss of interest, along with symptoms such as sleep and appetite disturbances, fatigue, difficulty concentrating, and thoughts of worthlessness or suicide. These symptoms must last at least two weeks and significantly impair daily functioning. In the United States, more than 21 million adults experience a major depressive episode each year. While several antidepressant medications are available, many individuals do not achieve adequate relief or discontinue treatment due to side effects like weight gain, sleep disruption, and sexual dysfunction. MDD is associated with increased risk of suicide and substantial impairment in quality of life, underscoring the urgent need for new, first-line therapies that are both effective and well-tolerated.
About TNX-102 SL TNX-102 SL is a patented sublingual tablet formulation of cyclobenzaprine hydrochloride that enables rapid transmucosal absorption and reduces production of the persistent active metabolite, norcyclobenzaprine, by bypassing first-pass hepatic metabolism. TNX-102 SL is a tertiary amine tricyclic (TAT) and multifunctional agent with potent binding and antagonist activities at the 5-HT2A serotonergic, α1-adrenergic, H1-histaminergic, and M1-muscarinic receptors. It is currently FDA approved in the U.S. as a once-daily bedtime treatment for fibromyalgia in adults under the brand name TONMYATM (cyclobenzaprine HCl sublingual tablets). TNX-102 SL is also in development as a daily bedtime treatment for acute stress reaction/acute stress disorder under an Investigator-initiated IND. In addition to MDD, Tonix also holds active INDs for the following indications for TNX-102 SL: Long COVID (post-acute sequelae of COVID-19), PTSD, alcohol use disorder, and agitation in Alzheimer’s disease. The United States Patent and Trademark Office issued United States Patent No. 9636408 in May 2017, Patent No. 9956188 in May 2018, Patent No. 10117936 in November 2018, Patent No. 10357465 in July 2019, and Patent No. 10736859 in August 2020. The Protectic™ protective eutectic and Angstro-Technology™ formulation claimed in the patents are important elements of Tonix’s proprietary composition. These patents are expected to provide TNX-102 SL U.S. market exclusivity until 2034. Pending patent applications related to method of use could extend exclusivity until 2044.

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 confirms 12 patients enrolled in Phase 2 THIO-101 to date as expansion trial adds new countries
Posters for Phase 2 and Phase 3 clinical trials available
CHICAGO , Nov. 21, 2025 (GLOBE NEWSWIRE) — MAIA Biotechnology, Inc. (NYSE American: MAIA) (“MAIA”, the “Company”), a clinical-stage biopharmaceutical company focused on developing targeted immunotherapies for cancer, today announced highlights from two poster presentations delivered at SITC 2025, an annual conference hosted by the Society for Immunotherapy of Cancer, held November 5-9, 2025, in National Harbor, MD. The Trials in Progress posters focus on MAIA’s ongoing Phase 2 THIO-101 expansion (Part C) and Phase 3 THIO-104 clinical trials of its first-in-class small molecule telomere targeting agent, ateganosine, as a treatment for non-small cell lung cancer (NSCLC). The U.S. Food and Drug Administration (FDA) has granted Fast Track designation for ateganosine for the treatment of NSCLC.
MAIA’s Sr. Medical Director, Victor Zaporojan, M.D., presenter at SITC 2025 commented, “It was a privilege to return to SITC for its 40th anniversary. This event was an ideal forum to highlight the continued success of our Phase 2 clinical trial. We are making steady progress in the expansion phase of this trial, with patient enrollment now underway in European Medicines Agency (EMA) countries. Sites in Hungary and Poland, which were instrumental in Parts A and B of the trial, are actively screening patients along Turkey and Taiwan, and we have 12 patients enrolled in the expansion to date. We expect further momentum in identifying and enrolling patients for THIO-101 Part C in the near term”.
“We also began screening patients in our Phase 3 trial, THIO-104, and noticed great excitement from physicians in the sites we’re bringing our trial to,” added MAIA CEO Vlad Vitoc, M.D. “In this population, third-line NSCLC patients resistant to chemo and immunotherapy, current treatments show overall survival (OS) of around 6 months, and based on the 17.8 months OS observed in THIO-101 to date, we believe that our Phase 3 trial could lead to an early commercial approval of ateganosine by the FDA. It’s only a matter of successful execution to bring our novel NSCLC treatment to this large patient population with significant unmet medical need.”
The posters presented at SITC 2025 feature trial designs for the Phase 2 and Phase 3 studies in advanced NSCLC patients receiving ateganosine followed by a checkpoint inhibitor, cemiplimab (Libtayo®). As of September 17, 2025, a patient that began therapy in March 2023 in the THIO-101 Phase 2 trial has shown survival of 30 months, or 912 days.
“A novel therapy with proven efficacy, such as ateganosine, could strengthen existing treatment strategies and further advance the principles of precision oncology in lung cancer care worldwide,” said Tomasz Jankowski, M.D., Ph.D., key investigator for THIO-101 in Poland and co-author of many of MAIA’s scientific posters. “In Poland, where improving outcomes in advanced NSCLC remains a central focus, ateganosine has the potential to become an important addition to the therapeutic landscape, offering new hope for patients and clinicians alike.”
The posters presented at SITC 2025 were attached as exhibits to a Current Report on Form 8-K filed by the Company with the Securities and Exchange Commission (the “Commission”) on November 7, 2025 and available on the Commission’s website at www.sec.gov. In addition, the posters were made available on MAIA’s website at maiabiotech.com/publications on November 7, 2025.
Presentation 1: 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
Presentation 2: A Phase 2 Study of Ateganosine (THIO; 6-thio-2′-deoxyguanosine) in Combination with Immune Checkpoint Inhibitor (ICI) in Patients with Advanced Non-Small Cell Lung Cancer (NSCLC) Resistant to Prior ICI and Chemotherapy: THIO-101 Trial in Progress
About Ateganosine
Ateganosine (THIO, 6-thio-dG or 6-thio-2’-deoxyguanosine) is a first-in-class investigational telomere-targeting agent currently in clinical development to evaluate its activity in non-small cell lung cancer (NSCLC). Telomeres, along with the enzyme telomerase, play a fundamental role in the survival of cancer cells and their resistance to current therapies. The modified nucleotide 6-thio-2’-deoxyguanosine induces telomerase-dependent telomeric DNA modification, DNA damage responses, and selective cancer cell death. Ateganosine-damaged telomeric fragments accumulate in cytosolic micronuclei and activates both innate (cGAS/STING) and adaptive (T-cell) immune responses. The sequential treatment of ateganosine followed by PD-(L)1 inhibitors resulted in profound and persistent tumor regression in advanced, in vivo cancer models by induction of cancer type–specific immune memory. Ateganosine is presently developed as a second or later line of treatment for NSCLC for patients that have progressed beyond the standard-of-care regimen of existing checkpoint inhibitors.
About THIO-101 Phase 2 Clinical Trial
THIO-101 is a multicenter, open-label, dose finding Phase 2 clinical trial. It is the first trial designed to evaluate ateganosine’s anti-tumor activity when followed by PD-(L)1 inhibition. The trial is testing the hypothesis that low doses of ateganosine administered prior to cemiplimab (Libtayo®) will enhance and prolong immune response in patients with advanced NSCLC who previously did not respond or developed resistance and progressed after first-line treatment regimen containing another checkpoint inhibitor. The trial design has two primary objectives: (1) to evaluate the safety and tolerability of ateganosine administered as an anticancer compound and a priming immune activator (2) to assess the clinical efficacy of ateganosine using Overall Response Rate (ORR) as the primary clinical endpoint. The expansion of the study will assess overall response rates (ORR) in advanced NSCLC patients receiving third line (3L) therapy who were resistant to previous checkpoint inhibitor treatments (CPI) and chemotherapy. Treatment with ateganosine followed by cemiplimab (Libtayo®) has shown an acceptable safety profile to date in a heavily pre-treated population. For more information on this Phase II trial, please visit ClinicalTrials.gov using the identifier NCT05208944.

Eli Lilly has officially crossed the $1 trillion valuation mark, becoming the first pharmaceutical company in history to join a market-cap club previously dominated almost entirely by technology giants. The milestone reflects a dramatic reshaping of the healthcare landscape, driven by surging global demand for next-generation weight-loss and metabolic health treatments.
Lilly’s rise has been nothing short of extraordinary. The company’s stock has rallied more than 35% this year alone, fueled largely by explosive growth in the obesity-drug category. Over the past two years, new and highly effective treatments have transformed weight-loss medicine into one of the most profitable segments in all of healthcare. What was once a niche market is now a multibillion-dollar engine attracting unprecedented consumer, medical, and investor interest.
At the center of Lilly’s success are two blockbuster drugs: tirzepatide, marketed as Mounjaro for type 2 diabetes and Zepbound for obesity. Together, they have rapidly climbed to the top of global pharmaceutical sales charts, surpassing even Merck’s cancer drug Keytruda — long considered untouchable as the world’s best-selling medication.
Although rival Novo Nordisk pioneered the modern obesity-drug movement with Wegovy, Lilly seized momentum after early supply shortages hampered Wegovy’s rollout. Stronger clinical results, faster manufacturing scale-up, and broader distribution helped Lilly pull ahead in prescriptions and capture the spotlight as the dominant player in the sector.
The company’s latest quarterly results underscore that shift. Lilly generated more than $10 billion in revenue from its obesity and diabetes medicines—over half of its total $17.6 billion in quarterly sales. Investors now value the company at nearly 50 times its expected earnings, signaling confidence that demand for metabolic-health treatments will remain powerful for years.
The broader market seems convinced as well. Since Zepbound’s launch in late 2023, Lilly shares have surged more than 75%, outpacing the S&P 500’s impressive run. Wall Street analysts estimate the global weight-loss drug market could reach $150 billion by 2030, with Lilly and Novo Nordisk expected to control the vast majority of those sales.
Looking ahead, investors are closely watching Lilly’s upcoming oral obesity drug, orforglipron, which could receive approval as early as next year. Analysts expect it to extend the company’s dominance by offering a pill-based alternative to injectable GLP-1 medications—an option that could unlock even wider adoption.
Beyond drug development, Lilly’s growth is poised to benefit from planned U.S. manufacturing expansions and a federal pricing agreement that is expected to increase patient access. Although the deal may reduce short-term revenue per dose, analysts believe the expanded eligibility—potentially adding tens of millions of U.S. patients—will dramatically enlarge the long-term market.
With its market cap now rivaling major tech players, Lilly is increasingly being viewed as a “Magnificent Seven-style” stock again—an alternative for investors seeking high-growth prospects outside AI and digital infrastructure. Still, challenges remain, including pricing pressure and the need to sustain manufacturing capacity at unprecedented scale.
For now, Lilly’s ascent to the $1 trillion tier signals a new era in which metabolic-health innovation, not just technology, can redefine global market leadership.
