La Jolla, California-based MediciNova (Nasdaq: MNOV) received a Notice of Allowance from the US Patent and Trademark Office for a method-of-treatment patent covering ibudilast (MN-166) in combination with an anti-PD-1 immune checkpoint inhibitor for glioblastoma treatment. The allowed claims span dosing regimen, route of administration, dosing frequency, dose levels, and duration of therapy, and are written broadly enough to encompass multiple anti-PD-1 antibodies rather than a single agent. Once formally issued, the patent is expected to expire no earlier than September 2042, providing MediciNova with a method-patent exclusivity runway of approximately 16 years in the US for this combination approach. The commercial significance is primarily strategic rather than immediately revenue-generating: MediciNova has not disclosed active Phase II or Phase III glioblastoma trial data, and ibudilast remains a known compound without composition-of-matter protection in this context. The allowance establishes intellectual property protection around the use of ibudilast with anti-PD-1 inhibitors in glioblastoma, which could support future partnership or licensing discussions if clinical evidence emerges. Ibudilast is a small-molecule inhibitor of phosphodiesterase type 4 (PDE4) and macrophage migration inhibitory factor (MIF), a pro-inflammatory cytokine implicated in immunosuppressive signaling within the tumor microenvironment. In glioblastoma, the tumor microenvironment is heavily immunosuppressive, characterized by M2-polarized tumor-associated macrophages and microglia that blunt T-cell activity. The mechanistic premise of the MN-166 combination therapy is that ibudilast’s suppression of MIF and modulation of PDE4-driven inflammatory signaling may remodel the immunosuppressive microenvironment, potentially augmenting the efficacy of anti-PD-1 checkpoint blockade by improving T-cell infiltration and activity at the tumor site. This rationale positions ibudilast as a tumor microenvironment modulator rather than a direct cytotoxic or immunostimulatory agent, distinguishing it mechanistically from conventional chemotherapy combinations with checkpoint inhibitors. Specific clinical results from MediciNova’s glioblastoma program remain undisclosed. The allowed claims cover the combination with anti-PD-1 antibodies as a class, which would encompass approved agents such as pembrolizumab (Keytruda) and nivolumab (Opdivo) without naming a single proprietary partner molecule. This breadth is meaningful for licensing flexibility but does not extend to anti-PD-L1 or CTLA-4 targeting approaches. MediciNova’s primary development efforts for ibudilast are focused on neurological indications including ALS, with the glioblastoma program appearing to remain at an earlier stage.

Australian oncology study advances into Cohort 3 as enrollment continues Entered the third and final dosing cohort of the Australian oncology study, expanded the Hemopurifier intellectual property portfolio, and maintained a focus on managing operating expenses. Conference Call Today at 4:30 p.m. ET SAN DIEGO, June 10, 2026 /PRNewswire/ -- Aethlon Medical, Inc. (the Company or Aethlon) (Nasdaq: AEMD), a clinical-stage medical therapeutic company focused on developing products to treat cancer and life-threatening viral infections for which there is no treatment, today reported financial results for its fiscal year ended March 31, 2026, and provided an update on recent developments. Key Highlights Advanced the Australian oncology study through completion of the first two cohorts and entered the third and final dosing cohort, representing a key clinical milestone toward generating data to inform future development and dosing strategy. Recently treated the first participant in Cohort 3 at Royal North Shore Hospital in Australia. The participant completed three Hemopurifier treatments over a one-week period, marking continued enrollment momentum and execution of the study's final treatment arm. Advanced preclinical research evaluating Hemopurifier applications in additional disease areas, including rheumatoid arthritis and chronic kidney disease, supporting the expansion of the platform's potential addressable market beyond oncology and infectious disease. Continued to strengthen the intellectual property portfolio supporting the Hemopurifier platform, including the issuance of patents in the United States and Europe covering potential applications for long COVID and other coronavirus-related conditions, extending patent protection into the 2040s and enhancing long-term platform value. "Fiscal 2026 was a year of meaningful execution for Aethlon as we advanced our Australian oncology study through the first two cohorts and recently initiated Cohort 3. Advancement into the final cohort represents an important clinical milestone as we work toward generating data that may help define the optimal treatment regimen and guide future development decisions. We also strengthened the Hemopurifier platform through expansion of our intellectual property portfolio and advancement of preclinical research supporting potential applications beyond oncology. Combined with our continued focus on managing operating expenses, these achievements position us to pursue multiple value-creating opportunities across our clinical and research programs." said James Frakes, Chief Executive Officer and Chief Financial Officer of Aethlon Medical. Clinical Update Clinical Progress in Cancer Trial Enrollment and treatment of participants in Cohort 2 of the Australian oncology trial have been completed. An independent Data Safety Monitoring Board reviewed the data, identified no safety concerns based on its review of available data, and recommended advancing to the third and final cohort. Screening is actively underway at the three investigative sites for this final cohort where 3-6 participants will be treated with 3 Hemopurifier sessions during a 1-week period. The first participant in Cohort 3 of the study has been enrolled and received three Hemopurifier treatments without any device deficiencies or immediate complications and is now in the follow-up period. Successful enrollment and treatment of the first participant in Cohort 3 maintains the study's clinical momentum and moves the Company closer to completing enrollment and generating data from all planned dosing regimens. Serial Extracellular Vesicle and T cell measurements on participants in cohort 2 have been measured by the central lab at the University of Sydney. Formal statistical analyses comparing the effects of the three different Hemopurifier dosing regimens on these parameters will be performed by a CRO at the completion of the trial. This nine-to-18 patient study is designed to evaluate the safety and feasibility of the Hemopurifier treatments and determine the appropriate dosing in participants with solid tumors whose disease is stable or progressing while on a treatment that includes the anti-PD-1 agents, Keytruda® or Opdivo®. Other Recent Developments During fiscal 2026, we strengthened our intellectual property portfolio through the issuance of patents in both the United States and Europe covering 2 potential applications of the Hemopurifier for coronavirus-related conditions; excessive clotting known as coagulopathy during acute COVID-19 infection and symptoms of Long COVID. These patents extend protection for certain applications of the Hemopurifier into the 2040s. In addition, we advanced our preclinical extracellular vesicle (EV) research activities, including studies evaluating removal of EVs in plasma samples from patients with rheumatoid arthritis and chronic kidney disease. These efforts support the Company's ongoing evaluation of the Hemopurifier's potential applications across multiple disease categories and may create future opportunities to expand the platform into large markets characterized by significant unmet medical need. Separately, we continued our evaluation of Hemopurifier compatibility with a simplified blood treatment system being developed by Stavro Medical. Initial testing assessing flow rates and transfer of fluid through the Hemopurifier has been completed, and future studies evaluating removal of surrogate markers for extracellular vesicles by the Hemopurifier using the system are under consideration. We believe this approach could expand potential treatment settings for the Hemopurifier in the future and may improve the scalability and accessibility of treatment if successfully developed and validated. Subsequent to fiscal year-end, an interview published in IEEE Spectrum featuring Aethlon's Chief Medical Officer and a physician involved in the treatment of an Ebola virus disease patient with the Hemopurifier during the 2014 outbreak highlighted the Company's experience with Ebola treatment efforts. In connection with renewed public health interest surrounding recent Ebola outbreaks, we also confirmed the continued availability of our FDA-authorized expanded access (compassionate use) protocol and shared the protocol as well as past in vitro and in vivo data with organizations involved in global and U.S. emerging pathogen preparedness efforts, including the World Health Organization's R&D Blueprint expert panel and the National Emerging Special Pathogen Training and Education Center. Financial Results for the Fiscal Year Ended March 31, 2026 As of March 31, 2026, the Company had approximately $5.0 million in cash and cash equivalents, providing resources to support ongoing clinical and research activities. Subsequent to fiscal year-end, the Company strengthened its balance sheet by raising approximately $1.85 million in net proceeds through its at-the-market program. Consolidated operating expenses declined 21.9% year-over-year to approximately $7.3 million, reflecting continued expense discipline and operational efficiency while advancing the Company's clinical and research priorities compared to $9.3 million for the fiscal year ended March 31, 2025. The decrease was primarily due to $1.1 million reduction in payroll and related expenses, a $500,000 reduction in general and administrative expenses and a $400,000 reduction in professional fees. Consistent with the reduction in operating expenses, the operating loss for the fiscal year decreased to approximately $7.3 million for fiscal 2026 from $9.3 million in the prior fiscal year. Other income was approximately $142,000 for the fiscal year ended March 31, 2026, primarily reflecting interest income earned on cash balances, compared to other expense of approximately $4 million in the prior fiscal year. The prior-year amount included approximately $4.7 million of non-cash financing-related charges. Net loss attributable to our common stockholders was $7.2 million for the fiscal year ended March 31, 2026, compared to net loss of $13.4 million for the fiscal year ended March 31, 2025.
