Multiple Ascending Dose Safety, Tolerability, PK Study of AL001 in Alzheimer's Disease Patients & Healthy Adult Subjects

Exclusion Criteria

• •Clinically significant abnormalities (as determined by investigator based on medical history, physical examination, vital sign measurements, ECG findings, or clinical laboratory findings) that may affect subject safety or successful study participation
• •Presence or history of any disorder that may prevent the successful completion of the study
• •Other severe acute, chronic, or historical medical or psychiatric condition or laboratory abnormality or social circumstance that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in judgment of the Investigator, would make the subject inappropriate for entry into this study
• •Evidence of clinically significant hematological, renal, endocrine, pulmonary, cardiovascular, dermatologic, muscular, or allergic disease or disorder (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing) that may affect the safety or successful participant of the subject
• •Any history or presence of gastrointestinal disease including chronic gastritis, hemorrhagic gastritis, peptic ulcers, duodenitis, diarrhea, or inflammatory bowel disease
• •Any presence or history of acute or chronic liver diseases
• •Any post-surgical or medical condition that may interfere with the absorption, distribution, metabolism, or excretion of the study treatment
• •Any history of frequent headache or migraine
• •Kidney disease (eGFR \<60 mL/minute/1.73 m2)
• •Uncontrolled tachy/brady arrhythmias, atrial fibrillation, or coronary heart failure

• •Presence of depression, except for mild depression with no acute episodes and stable condition, as determined by the Investigator
• •History of untreated thyroid dysfunction that may be independently associated with cognitive impairment
• •Central nervous system-related exclusions:
• •1. any medical condition that (per investigator's judgement) would affect subject safety and scientific integrity of the study, e.g., untreated hypothyroidism (TSH \>10 mIU/L) or vitamin B12 deficiency (\<300 pg/mL) which may contribute to cognitive impairment, delirium, non-AD dementia and other encephalopathies
• •2. Hachinski scale score \>4 or evidence of stroke within the past 5 years
• •Systemic related exclusions:
• •1. Active cancer (except squamous cell and basal skin cancers) requiring chemo- or radiation therapy
• •2. Positive test results for HIV, HBV, and HCV (unless quantitative PCR negative for HCV) at Screening
• •3. Uncontrolled hypertension with a sustained blood pressure \>160/100 mmHg at Screening, check-in (Day -1), and prior to the first study drug administration
• •4. Fever (body temperature \>101.4°F \[38.5°C\]), acute upper respiratory, or any other infections at Screening, check-in (Day -1), and prior to the first study drug administration
• •Any history of drug hypersensitivity, asthma (with the exception of childhood asthma), urticaria or other severe allergic diathesis
• •History of adverse - or hypersensitivity reaction to lithium, aspirin, salicylate, L-proline, or any test article excipient
• •Female who is breastfeeding, pregnant according to the pregnancy test at Screening or prior to the first study drug administration, or planning to become pregnant during the study
• •History of drug abuse (barbiturate, amphetamine, benzodiazepine, cocaine, opiates and cannabis) within the last 12 months or a positive urine drug screen at Screening or Day -1
• •Admitted alcohol abuse or history of alcohol use that may interfere with the subject's ability to comply with the protocol requirements or positive alcohol test at Screening or Day -1.
• •More than moderate current alcohol consumption (subjects will be advised to consume no more than 2 units of alcohol/d and completely abstain from 72 hours prior to any visit.
• •Treatment with haloperidol, antipsychotics, monoamine oxidase inhibitors, or neuromuscular blocking agents. An appropriate drug-free period will be required for washout, particularly for any especially long half-life drugs.
• •Hyponatremia, defined as serum sodium laboratory value outside the standard reference range
• •Suspected of having or at risk for Brugada Syndrome
• •Prescribed or OTC use of a salicylate-containing product other than low-dose aspirin for cardioprotection (e.g., aspirin, bismuth sub-salicylate, salicylazosulfapyridine \[sulfasalazine\]) from 1 week before first dose to 1 week after last dosing; any other prescribed anticoagulant medication
• •Consumption of poppy seeds or quinine (tonic water) 48 hours prior to Day 1
• •Aspirin/nasal polyposis/asthma syndrome
• •Participation in a clinical trial and receipt of an investigational medication within 30 days or 5 half-lives (if known), whichever is greater, prior to the first dose of the current study drug.
• •Clinically significant abnormalities detected by medical history, physical examination, vital sign measurements, ECG findings, or clinical laboratory findings or any historical or present condition/ treatment that may prevent successful or safe study completion, including substance abuse, kidney disease (estimated glomerular filtration rate \[eGFR\] \<60 mL/minute/1.73 m2) or hyponatremia
• •Use of any medication on a chronic basis except an oral contraceptive, with appropriate washout of prescription, OTC, vitamins and herbal supplements
