Brief summary

This is a Phase 1/2a, multi-center, placebo-controlled, double-blinded, randomized, multiple ascending dose (MAD) clinical trial to determine the safety and maximum tolerated dose of AL001. Up to 72 participants will be randomly assigned to receive study drug (active AL001) or placebo. The study consists of a 4-week screening period, a 14-day treatment period, and a 42-day follow-up period.

Detailed description

This is a Phase 1/2a, multi-center, placebo-controlled, double-blind, randomized, multiple ascending dose (MAD) clinical trial to determine the safety and maximum tolerated dose (MTD) of AL001, a crystal engineered lithium-salicylate-proline lithium delivery product that in nonclinical studies was shown to enhance and prolong the pharmacokinetic (PK) profile of lithium in the brain with enhanced efficacy potential in Alzheimer's models compared to lithium carbonate. A maximum of approximately 72 participants will be enrolled. Participants will be randomly assigned to receive study drug (active AL001) or placebo in a ratio of 6:2, respectively, with 8 patients in each dosing cohort. Placebos will be pooled and regarded as a comparative cohort for safety. Cohorts 2a, 3a, 4a and 5a will involve 1:1 healthy non-elderly and elderly subjects; cohorts 1, 2b, 3b, 4b and 5b will involve Alzheimer's subjects. The study will consist of a screening period (Days -28 to -2), a 14-day treatment period, and a 42-day follow-up period.

Multiple Ascending Doses of AL001- Cohort 1 (1890 mg AL001/d, 630mg TID ×14 Days)
AD-only participants (no normal healthy subjects) were randomized to receive AL001. When adequate safety data were available, a review was done for all participants to make a dose-escalation or dose and/or regimen modification decision. This was repeated for each cohort. A total of 8 cohorts received 5 different dose levels of AL001 in multiple ascending doses under fasted conditions up to tolerability/safety limits. Cohort 1 included 6 AD subjects only (7 were randomized because 1 subject voluntarily withdrew before dosing); 6 active AD subjects (as per randomization code) received the following treatment: • Cohort 1: 60% of 450 mg lithium carbonate equivalent of AL001 (1890 mg AL001 daily ×14 days, given as 3 × 210 mg AL001 capsules TID) AL 001: a crystal engineered lithium-salicylate-proline lithium delivery product.

The data from the previous cohort were deemed safe before the next sequential cohort was enrolled and dosing initiated. Cohort 4 was divided into 2 sub-cohorts: Cohort 4a (6 healthy subjects - 3 non-elderly adults and 3 elderly adults) and Cohort 4b (6 AD subjects). Blinded results from Cohort 4a were reviewed by the safety review committee before Cohort 4b was randomized. Per randomization, there were 6 active subjects in each cohort: • Cohort 4b: 160% of 450 mg lithium carbonate equivalent of AL001 (5040 mg AL001 daily × 14 days, given as 8 × 210 mg AL001 capsules TID) AL 001: a crystal engineered lithium-salicylate-proline lithium delivery product.

Multiple Ascending Doses of AL001 - Cohort 5a (6300 mg AL001/d, 2100mg TID × 14 Days)
The data from the previous cohort were deemed safe before the next sequential cohort was enrolled and dosing initiated. Cohort 5 was planned to be divided into 2 sub-cohorts: Cohort 5a (6 healthy subjects - 3 non-elderly adults and 3 elderly adults) and Cohort 5b (6 AD subjects). Per randomization, there were 6 active normal healthy subjects in cohort 5a. Stopping rules were invoked by the Safety Committee due to the pharmacokinetic results of Cohort 5a. The Stopping Rules were not invoked due to any adverse event. The stopping criteria were modest increases in plasma levels of lithium and salicylate above what is reported in the literature as the maximum therapeutic range concentrations. • Cohort 5a: 200% of 450 mg lithium carbonate equivalent of AL001 (6300 mg AL001 daily × 14 days - lithium dose equivalent to that used for bipolar/affective disorders, given as 10 × 210 mg AL001 capsules TID) AL 001: a crystal engineered lithium-salicylate-proline lithium delivery product.
6
Multiple Ascending Doses of AL001 - Cohort 5b (6300 mg AL001/d, 2100mg TID × 14 Days)
Subjects for Cohort 5b (6 AD subjects) were not enrolled because the Safety Committee invoked study stopping rules due to the pharmacokinetic results of Cohort 5a. The Stopping Rules were not invoked due to any adverse event. The stopping criteria were modest increases in plasma levels of lithium and salicylate above what is reported in the literature as the maximum therapeutic range concentrations. • Cohort 5b was not dosed. Subjects would have been dosed at 200% of 450 mg lithium carbonate equivalent of AL001 (6300 mg AL001 daily × 14 days - lithium dose equivalent to that used for bipolar/affective disorders, given as 10 × 210 mg AL001 capsules TID) AL 001: a crystal engineered lithium-salicylate-proline lithium delivery product.

Number of Participants With Serious AEs, TEAEs That Lead to Premature Discontinuation, Abnormal Laboratory Test Results, Abnormal ECG Readings.

To evaluate the safety and tolerability of AL001 in healthy subjects and patients with adverse event(s), AD, descriptive statistics will be presented by treatment group for each cohort and overall, for the following: Proportion of participants with treatment-emergent adverse events (TEAEs) * Proportion of participants with serious AEs * Proportion of participants with TEAEs that lead to premature discontinuation * Proportion of participants with abnormal values for each safety laboratory test (change from baseline) * Proportion of participants with abnormal values for each Electrocardiogram (ECG) parameter (change from baseline in standard 12-lead ECG parameters) For all analyses, placebo-treated subjects from each Cohort were combined (pooled) to provide a composite placebo group for all comparisons. Adverse event profiles for all treated subjects were benign as were placebo-treated subjects. No further statistical analyses were therefore appropriate.

Time frame: 42 days with a 14-day treatment period

Population: All subjects in the Randomized Analysis Set who received any dose of the study drug. This analysis set was used for all safety analyses.

Maximum Tolerated Dose of AL001 (Lithium Component) in All Subjects Treated With AL001

To characterize the MTD of AL001 in all subjects treated with AL001: • Proportion of subjects in each Cohort with plasma trough measurements of lithium \> 1.0 mEq/L. Subjects above these values invoke stopping rules for subsequent cohort enrollment.

Time frame: 42 days with a 14-day treatment period

Population: All subjects in the Safety Analysis Set who received AL001 and had a trough measurement for lithium.
