- Topline data expected in December 2022 from Phase IIA Multiple Ascending Dose Clinical Trial for AL001 Treatment of Dementia Related to Alzheimer’s
- Full data from Phase I first-in-human study demonstrated AL001 in plasma is bioequivalent to the marketed lithium carbonate product
Alzamend Neuro, Inc. (Nasdaq: ALZN) (“Alzamend”), an early clinical-stage biopharmaceutical company focused on developing novel products for the treatment of Alzheimer’s disease (“Alzheimer’s”), bipolar disorder, major depressive disorder (“MDD”) and post-traumatic stress disorder (“PTSD”), today announced that it has received a written response to its meeting request relating to its Type B Pre-Investigational New Drug (“IND”) application from the U.S. Food and Drug Administration (the “FDA”). The FDA’s response provides a path for Alzamend’s planned clinical development of AL001 for the treatment of bipolar disorder, MDD and PTSD. AL001 is a novel lithium-delivery system; specifically, it is a lithium-salicylate-L-proline engineered ionic cocrystal under development as an oral treatment for patients with dementia resulting from mild, moderate or severe cognitive impairment caused by Alzheimer’s. AL001 has the potential to deliver benefits of marketed lithium carbonate while mitigating or avoiding current toxicities associated with lithium.
Lithium was the first mood stabilizer and is still a first-line treatment option, but is underutilized, perhaps because of the need for therapeutic drug monitoring (“TDM”) to assure safe and effective blood concentrations, and the availability of newer treatments. Lithium is a commonly prescribed drug for manic episodes in bipolar disorder as well as maintenance therapy of bipolar disorder in patients with a history of manic episodes. The primary target symptoms of bipolar disorder are mania and mood swings. Lithium is also prescribed off-label for MDD (often as an adjunct therapy), bipolar disorder (without a history of mania), and treatment of PTSD, among other neurodegenerative, neurological and neuropsychiatric disorders.
Lithium was the first drug that required TDM by regulatory authorities in product labelling because the effective and safe range of therapeutic drug blood concentrations is narrow and well defined for treatment of bipolar disorder when using lithium salts. Excursions above this range can be toxic. AL001 may enhance lithium distribution into target tissues in the central nervous system (brain) but at lower systemic exposures, resulting in an improved safety profile compared to lithium salts, including the possibility of mitigating lithium side effects and the current requirement for TDM.
In a Phase I relative bioavailability comparison of AL001 to lithium carbonate completed in March 2022, AL001 was shown to provide dose-normalized bioequivalent plasma pharmacokinetics and the observed safety profile was benign. A phase IIA, Multiple Ascending Dose (“MAD”) clinical trial for the treatment of dementia related to Alzheimer’s is currently underway. Alzamend plans to conduct further studies designed to enable it to ascertain comparative brain penetration and persistence of AL001 to lithium carbonate. These studies are expected to help predict observations seen in pharmacokinetic nonclinical findings to improve treatments in humans, including the potential for AL001 to exhibit lithium dose sparing properties that could mitigate lithium side effects and the current requirement for TDM in blood. Lithium was the first drug that required TDM by regulatory authorities in product labelling because the effective and safe range of therapeutic drug blood concentrations is narrow and well defined for treatment of bipolar disorder when using lithium salts. Excursions above this range can be toxic. Since providing a greater concentration of lithium to the brain while minimizing the amount of the drug delivered to other organs can improve overall safety, AL001 has the potential to provide a safer product compared to currently marketed lithium salts.
“We appreciate the thorough and meaningful response from the FDA, which provides us with the information and clarity needed to submit IND applications to initiate clinical trials for AL001 for the treatment of bipolar disorder, MDD and PTSD,” said Stephan Jackman, Chief Executive Officer of Alzamend. “We are one step closer to substantiating that AL001 can potentially provide clinicians with a major improvement over current lithium-based treatments and may constitute a means of treating over 40 million Americans suffering from Alzheimer’s, bipolar disorder, MDD, and PTSD. We appreciate the FDA’s recommendations, guidance, and other helpful advice. We plan to enhance our proposed clinical trial protocols and proceed accordingly.”
Based on the FDA’s written feedback, Alzamend anticipates filing the INDs for bipolar disorder, MDD and PTSD upon the completion of the current Phase IIA MAD study. This will allow Alzamend to initiate Phase II clinical trials for all three new indications.
About AL001 Phase IIA Study
The ongoing Phase IIA study is evaluating the safety and tolerability of AL001 under multiple-dose, steady‑state conditions and is determining the maximum tolerated dose in patients diagnosed with mild to moderate Alzheimer’s. Lithium has been well characterized for safety and is approved/marketed in multiple formulations for bipolar disorder. Lithium dosing for the MAD cohorts consists of fractions of a usual dose for treatment of bipolar disorder. In each cohort, consisting of six active and two placebo patients (as per randomization), multiple ascending doses are being administered three times daily for 14 days under fasted conditions (at least one hour before or four hours after meals) up to tolerability/safety limits for this fragile Alzheimer’s population. The lithium and salicylate components of AL001 are to be given within the amounts already approved for use in patients for other indications. Up to 40 subjects will complete the Phase IIA trial. The maximum tolerated dose will then be used for further studies. The Phase IIA study commenced on May 5, 2022. More information can be found at www.clinicaltrials.gov, identifier: NCT05363293.
About AL001 Phase I Study
During this Phase 1 trial, participants received a single dose of AL001 containing lithium in an amount equivalent to 150 mg lithium carbonate, a dose proposed as likely appropriate for Alzheimer’s treatment when given three times daily. Currently, marketed lithium carbonate 300 mg capsules are often given three times daily when prescribed for manic episodes in bipolar disorder as well as for maintenance therapy of bipolar disorder in patients with a history of manic episodes. It can be difficult to control the appropriate dose of lithium salt formulations, including lithium carbonate, due to the small margin between effective and toxic blood levels, and therefore it can be challenging to avoid side effects or inadequate treatment outcomes.
Dose-adjusted relative bioavailability analyses of the rate and extent of lithium absorption in plasma indicated that AL001 at 150 mg lithium carbonate equivalent dosage is bioequivalent when dose-normalized to the marketed 300 mg lithium carbonate product and the shapes of the lithium plasma concentration versus time curves are highly similar. Based on the Phase I study results, it has been shown that dose-normalized systemic bioequivalence for lithium was established between AL001 and the marketed reference lithium carbonate 300 mg capsule. Findings of plasma bioequivalence to a marketed lithium product may allow Alzamend to design a development program that will potentially reduce the amount of new data generated to support approval. Demonstrated systemic bioequivalence also may have utility for AL001 when seeking approval for new indications as a benchmark for safety.
