The first patient, treated at the lead clinical site, The Christie NHS Foundation Trust received all three planned doses of the drug candidate ZI-MA4-1 on Days 1, 4 and 8 of the treatment cycle, followed by a protocol defined safety observation period. An independent group of medical and scientific experts – the IDMC – has now reviewed these data. Following its review, the IDMC identified no dose-limiting toxicities or other safety concerns that would preclude continuation of the study at the current dose level. The committee therefore recommended that the study proceed with enrolment of two additional patients at the same dose level.

ZIMA-101 follows a stepwise approach commonly used in early-stage clinical trials, where safety is carefully assessed before additional patients are treated. Following the IDMC’s recommendation, the study can now proceed with enrolment of two additional patients at the first dose level. Patient screening and recruitment are ongoing at both clinical sites in the United Kingdom – The Christie and The Royal Marsden NHS Foundation Trust.

These initial safety observations represent the first clinical data from the ZIMA-101 study, consistent with the Company’s previously communicated guidance that initial clinical data would begin to emerge from mid-2026. The Company expects further data to emerge as additional patients are enrolled and followed over time.

"These encouraging initial safety observations represent an important first step in the clinical evaluation of ZI-MA4-1 and our TCR-NK platform" said Namir Hassan, Chief Executive Officer of Zelluna. "The first patient received all three planned doses, and the independent committee’s recommendation enables us to continue recruitment at the first dose level. We are pleased with the progress to date, while remaining mindful that the study is still at an early stage. We stay firmly focused on patient safety, disciplined clinical execution and the careful generation of further data."

Professor Fiona Thistlethwaite, Consultant Medical Oncologist at The Christie and honorary professor at The University of Manchester said "Following the IDMC review meeting we are very pleased to have permission to continue recruitment and offer the opportunity to patients to participate in this exciting study".

About ZIMA-101

ZIMA-101 is a Phase 1 clinical trial evaluating the safety, tolerability and preliminary anti-tumour activity of ZI-MA4-1 in patients with advanced solid tumours that express the protein MAGE-A4. The study is being conducted at The Christie and The Royal Marsden NHS Foundation Trusts in the United Kingdom. The study design involves treating three patients at each dose level, with an independent committee reviewing safety data from the first patient before recommending enrolment of the remaining two patients at that dose level.

About ZI-MA4-1

ZI-MA4-1 is Zelluna’s lead allogeneic TCR-NK product candidate and the world’s first MAGE-A4-targeting TCR-NK cell- therapy in clinical development. The product combines the natural tumour-killing ability of NK cells with precision targeting of MAGE-A4 – a protein found on the surface of several common cancer types, including ovarian cancer, lung cancer, synovial sarcoma and head and neck cancer. The therapy is manufactured as an "off-the-shelf" product that can be administered directly to patients without individual customisation, making it more accessible than traditional cell therapies.

We are collaborating with experts from Duke University School of Medicine to develop EVX-05. This program targets endogenous retrovirus (ERV)-derived antigens shared between glioblastoma patients, which AI-Immunology has unique capabilities in identifying. These ERV-antigens constitute a novel source of highly attractive targets for off-the-shelf cancer vaccines.

With its new therapeutic concept, EVX-05 is being developed as a novel therapeutic approach for glioblastoma. Current therapies are often inadequate, meaning glioblastoma remains one of the most aggressive and deadly cancers.

"We are delighted to transform our discoveries in glioblastoma into a promising new vaccine program with EVX-05, which could hold a significant therapeutic potential in area of massive unmet medical need. We have an outstanding collaboration with Duke University and now see the huge benefits of combining their extensive disease understanding and clinical expertise with the unique target discovery capabilities of AI-Immunology," says Birgitte Rønø, CSO and COO of Evaxion.

"Patients with glioblastoma continue to face limited treatment options and poor outcomes," said Mustafa Khasraw, M.D., professor at Duke University School of Medicine. "The potential of ERVs as therapeutic targets has long been acknowledged, if we can unlock this potential, it would be a significant advancement towards improving care."

World-leading expertise
Evaxion is currently undertaking optimization of a lead vaccine candidate for the EVX-05 program as part of advancing it towards initial clinical testing. This is expected to be carried out by Professor Khasraw and his team, allowing for world-leading clinical expertise and knowledge of patient needs to help guide clinical development. The collaboration also potentially allows a cost-efficient way for Evaxion to study EVX-05 in a clinical phase 1 trial.

EVX-05 builds on the same ground-breaking ERV-targeting concept as EVX-04, Evaxion’s vaccine candidate against acute myeloid leukemia. This confirms the broad applicability of the concept across cancers where immunotherapies remain inadequate and conserved immunogenic antigens can be identified.

Both programs draw on learnings from the EVX-03 program, which has now been discontinued and removed from our R&D pipeline as a matter of portfolio management. The costs related to EVX-05 are captured within Evaxion’s existing budgets and hence does not impact on our cash runway, which continues to stretch into second half of 2027.

Conference call and webcast
This coming Thursday, August 20, Evaxion’s Executive Management will host a conference call and webcast at 8.30 ET/14.30 CET today, presenting our Q2 2026 business update and financial results as well as taking questions. EVX-05 will be one of the topics discussed.

About glioblastoma
Glioblastoma is the most aggressive malignant primary brain tumor. It has an incidence rate of 3.19 per 100,000 persons in the United States and a median age of 64 years (National Institute of Health).

No cure exists for glioblastoma, and treatment outcomes remain poor: 50% of patients die approximately one year from diagnosis (New England Journal of Medicine, 2005).

The allowed claims protect compositions of ART27.13 dispersed in polyethylene glycol, including the Company’s intended commercial formulation. This development marks a major milestone in Artelo’s global intellectual property strategy and positions the Company for long-term value creation.

"This U.S. Notice of Allowance and near-term expectation of the issuance of the patent further strengthens the intellectual property foundation supporting ART27.13 and its long-term development potential," said Gregory D. Gorgas, President and Chief Executive Officer of Artelo Biosciences. "As ART27.13 advances in multiple Phase 2 studies, we believe protecting the intended commercial formulation is an important step in building value around the program and preserving opportunities across multiple indications."

ART27.13 is being evaluated in the Phase 2 portion of CAReS trial targeting cancer-related anorexia. The investigational drug was well tolerated in the Phase 1 stage and showed early signs of stabilizing or reversing weight loss in more than 60% of participants. Interim results from the Phase 2 portion of CAReS demonstrated the ability of the drug to reverse cancer-related anorexia in all patients taking the highest dose whereas the all the participants on placebo continued to lose weight throughout the study.

ART27.13 is also being evaluated in the DREAM study, a Phase 2 in patients with glaucoma or ocular hypertension. The investigator-led study, funded by Glaucoma UK and the HSC R&D Division, is evaluating ART27.13’s potential as a once-daily, orally administered treatment to reduce intraocular pressure, with initial results anticipated in the fourth quarter of this year.

About ART27.13
ART27.13 is a novel benzimidazole derivative and dual cannabinoid agonist. Initially developed by AstraZeneca plc, ART27.13 has been in seven clinical studies with over 280 participants. It is being developed as a once-daily, orally administered agent selectively targeting peripheral CB1 and CB2 receptors, with the potential to reduce muscle degeneration while improving body weight, appetite, and quality of life in cancer patients. A statistically significant and dose-dependent increase in body weight was observed in people with back pain who were otherwise healthy. Importantly, the drug enables systemic metabolic effects while minimizing central nervous system-mediated toxicity. Artelo is conducting a Phase 2 named the Cancer Appetite Recovery Study (CAReS) evaluating ART27.13 as a supportive care therapy for cancer patients suffering from anorexia and weight loss. Interim Phase 2 data revealed patients who had lost at least 5% of body weight to be included in CAReS and titrated to the highest ART27.13 dose (1300 µg) achieved an average +6% weight gain over 12 weeks, while patients on placebo lost an additional ~5%. Currently, there is no FDA approved treatment for cancer anorexia cachexia syndrome. In addition to CAReS, ART27.13 is also being evaluated in a Phase 2 study in people with glaucoma at a daily dose of 650 µg.

The focus of the meeting will be to align on the pivotal Phase 3 clinical trial design criteria, including the number of patients to be enrolled along with primary and secondary endpoints. The regulators will also be reviewing the data from the Phase 2b trial of RAD 101, which demonstrated 93% concordance between MRI and PET imaging of brain metastases in this patient population with suspected recurrence. The results showed substantial and selective tumor uptake of RAD101, with images confirming metabolic activity in PET compared to equivocal MRI findings.

"We are pleased to have secured an End-of-Phase 2 meeting with the FDA for RAD101, an important milestone that brings us closer to advancing this promising imaging agent into a pivotal Phase 3 program," said Riccardo Canevari, CEO and Managing Director of Radiopharm Theranostics. "We believe the upcoming discussion will provide important alignment on the clinical and regulatory pathway forward, enabling us to finalize plans for a registrational study and remain on track to be Phase 3-ready by year-end. Supported by the strong Phase 2b data demonstrating 93% concordance with MRI, we believe RAD101 has the potential to address a meaningful unmet need in the diagnosis of recurrent brain metastases and create significant value for patients, clinicians, and shareholders."

RAD 101 has received FDA Fast Track Designation to distinguish between recurrent disease and treatment effect of brain metastases originating from solid tumors of different origin including leptomeningeal disease. The company also recently announced a partnership with Siemens Healthineers, who will manufacture and distribute doses of 18F-labeled RAD101 to support Radiopharm’s upcoming Phase 3 registrational trial in the U.S.

In the U.S. alone, there are more than 300,000 patients diagnosed annually with cerebral metastases. The incidence of Intracranial Metastatic Disease (IMD) continues to increase, in part, due to improvements in systemic therapy resulting in a more durable control of the Primary tumor. Contrast-enhanced Magnetic Resonance Imaging (CE-MRI) is the preferred method for imaging IMD, but has limitations, particularly in follow-up surveillance scans to optimise patient care.1

About RAD101

RAD101 is the Company’s novel imaging small molecule that selectively binds to fatty acid synthase (FASN), a multi-enzyme protein that catalyses de-novo fatty acid synthesis and is overexpressed in cerebral metastasis from solid tumors. Targeting FASN activity may allow for the more accurate detection of cancer cells in the CNS, representing a clinically relevant method for the imaging of brain metastases. Positive data from the Imperial College of London’s Phase 2a imaging trial of 18F-RAD101 in patients with brain metastases (both SRS pre-treated and treatment naïve patients) showed significant tumor uptake that was independent from the tumor of origin. The study further indicated that PET-MRI may potentially represent a non-invasive prediction of overall-survival, warranting larger studies.
