Alzamend Neuro Reports Positive Topline Data from Phase II Clinical Trial of AL001 "Lithium in Brain" Study; AL001 Achieves Bioequivalence and Demonstrates Superior Brain Delivery Across All Measured Brain Regions

• Bioequivalence Confirmed: AL001 delivered 101% of total lithium blood exposure and 97% of peak lithium levels vs. standard lithium carbonate
• Superior Brain Penetration: AL001 showed numerically higher lithium concentrations in all measured brain regions, including whole brain
• Faster Brain Uptake: AL001 reached peak brain concentration in 6.7 hours vs. 8.4 hours for standard lithium carbonate

ATLANTA, March 26, 2026 /PRNewswire/ -- Alzamend Neuro, Inc. (NASDAQ:ALZN) ("Alzamend"), a clinical-stage biopharmaceutical company focused on developing novel products for the treatment of Alzheimer's disease ("Alzheimer's"), bipolar disorder type 1 ("BD"), major depressive disorder ("MDD") and post-traumatic stress disorder ("PTSD"), today announced positive topline data from its first Phase II "Lithium in Brain" clinical trial in healthy human subjects, demonstrating that AL001 meets bioequivalence standards while also showing numerically superior lithium delivery to the brain compared to standard lithium carbonate across all 26 measured brain regions including whole brain. These results suggest a promising differentiated pharmacological profile with significant implications for patients with Alzheimer's, BD, MDD and PTSD. The trial was conducted at Massachusetts General Hospital ("MGH") and represents a meaningful clinical and regulatory advance for AL001.

Phase II Topline Results

• AL001 Achieves Bioequivalence with Standard Lithium Carbonate:
  • The U.S. Food and Drug Administration (the "FDA") requires a new formulation to deliver between 80% to 125% of the reference drug to the bloodstream to support equivalent systemic safety. AL001 delivered 101% of total lithium exposure and 97% of peak lithium levels compared to standard lithium carbonate, which are both squarely within the required FDA range. Achieving bioequivalence supports a Section 505(b)2 new drug application submission for safety, potentially mitigating non-clinical requirements.
• Superior Brain Penetration Across all 26 Measured Regions, Including Whole Brain:
  • Using a one-of-a-kind Tesla head coil that provides advanced magnetic resonance imaging ("MRI") and magnetic resonance spectroscopy ("MRS") neuroimaging, researchers quantified lithium in 25 discrete brain regions as well as the whole brain. AL001 showed numerically higher lithium concentrations in every single region vs. standard lithium carbonate, including the hippocampus (memory), entorhinal cortex (early Alzheimer's target), cingulate gyrus (cognition), amygdala and accumbens regions. Maximum whole-brain lithium exposure increased ~7.8% for AL001 compared to lithium carbonate. A consistent directional increase across all measured brain regions is a compelling signal, and confirmation is already underway; the second of five planned Phase II trials, enrolling a total of 30 patients across the full program, is already underway at MGH.
• Faster Brain Uptake Results in Earlier Peak Concentration:
  • AL001 achieved peak brain lithium concentrations at 6.7 hours compared to 8.4 hours for standard lithium carbonate, resulting in a potential ~1.7-hour advantage. Faster brain uptake could have meaningful implications for therapeutic onset and dosing optimization, which will be evaluated in subsequent studies.
• Second Phase II Clinical Trial Already Underway at MGH:
  • In this first study, brain tissue measurements were conducted in six subjects per arm, which is a sample size that produces directionally meaningful, but not yet statistically definitive, results. The ~7.8% whole-brain lithium trend is worthy of further investigation. To that end, Alzamend has initiated its second Phase II "Lithium in Brain" clinical trial at MGH, this time in patients with BD, with topline data expected in the third quarter of 2026. The third, fourth, and fifth studies in the program enrolling patients with MDD, PTSD and Alzheimer's, respectively, are anticipated to begin in the latter half of 2026, subject to raising sufficient capital. Alzamend believes that results across all five studies, totaling 30 patients, will be adequate to establish statistical significance and advance AL001 toward further regulatory milestones.

"These data mark a pivotal advancement in the development of AL001," said Stephan Jackman, CEO of Alzamend. "We have clinical evidence that AL001 shows equivalent delivery of lithium in the bloodstream compared to standard lithium carbonate capsules, which is a key regulatory safety measure. And the brain data, while preliminary, show a consistent increase providing higher lithium in every brain region we measured. This can permit lower systemic doses to achieve efficacy thereby providing an enhanced safety profile. Combined with the faster brain uptake, we believe AL001 has a meaningfully differentiated profile compared to conventional lithium; one that could benefit the 43+ million Americans afflicted with Alzheimer's, BD, MDD and PTSD."

AL001: A Differentiated Lithium Therapy for a Large Unmet Need

Although lithium has remained the gold standard treatment for BD for more than 55 years, its clinical utility is constrained by a narrow therapeutic window and the need for regular therapeutic drug monitoring ("TDM") to manage renal, thyroid, and other systemic toxicity risks. AL001 is Alzamend's patented ionic cocrystal formulation of lithium combined for delivery with L-proline and salicylate, which is designed to deliver a full therapeutic amount of lithium to the brain with less systemic exposure than lithium carbonate, potentially enabling a safer, better-tolerated therapy across Alzheimer's, BD, MDD and PTSD.

About this Study

The study employed a randomized crossover design with multiple six-subject cohorts. Participants were assigned to one of two sequences: AB (AL001 then lithium carbonate) or BA (lithium carbonate then AL001). Each treatment period consisted of 14 days of three-times-daily ("TID") dosing, separated by a 14-day washout.

On Days 14–15, participants underwent 24-hour pharmacokinetic blood sampling alongside advanced MRI and MRS neuroimaging, a first-of-its-kind methodology. The MRI and MRS neuroimaging methods were developed by the lab of Dr. Ovidiu Andronesi, the study's principal investigator, Associate Professor of Radiology at Harvard University and the Director of Multinuclear Metabolic Imaging, Martinos Center for Biomedical Imaging, Department of Radiology, MGH, Harvard Medical School. The study also incorporated a specialized, engineered head coil developed by Tesla Dynamic Coils BV, designed to enable high-resolution, whole-brain lithium imaging. This approach enabled simultaneous quantification of lithium concentrations in blood and brain including individual structures, as well as assessment of brain and individual brain structure chemistry, metabolism, and biomarker effects.

The study specifically evaluated AL001's ability to enhance lithium delivery to targeted brain regions while reducing systemic exposure, an approach designed to address the long-standing safety and tolerability limitations associated with traditional lithium salts. The results from the study confirmed that AL001 matches blood levels of standard lithium carbonate, the reference drug, addressing FDA regulatory requirements for a new drug formulation, as well as providing a differentiated, potential dose-sparing benefit profile for patients.
