Study Purpose:This is a Phase IIa, randomized, open-label, multi-center, multi-dose study for subjects with mild to moderate ALS. The protocol is designed to determine whether ALZT-OP1a treatment will positively impact neuro-inflammatory biomarkers and slow down or arrest functional decline in subjects with mild to moderate ALS.

Full Study Summary:
Up to 80 evaluable subjects will be randomly assigned to one of two treatment groups: Group I (n=40) will consist of low dose ALZT-OP1a, administered via dry powder inhalation; OR Group II (n=40), which will consist of high dose ALZT-OP1a, administered via dry powder inhaler.
Subjects will dose for 12 weeks and will be asked to return to the site for scheduled visits and biomarker collection at Week 4, Week 8, and Week 12.

- Familial or sporadic ALS diagnosed as possible, laboratory-supported probable, probable, or definite as defined by revised El Escorial criteria;
- Disease duration from ALS diagnosis ≤24 months;
- ALSFRS-R total score ≥ 36 at screening visit;
- ALSFRS-R Breathing sub-score should be ≥9 at the time of screening;
- ALSFRS-R Bulbar sub-score should be ≥9 at the time of screening;
- Peak inspiratory flow rate (PIFR) ≥ 100 L/minute;
- Forced vital capacity (FVC) >70% of predicted value;
- Participant must be receiving treatment with stable dose of standard of care treatment for ≥30 days prior to signing informed consent.
- Subjects with bulbar-onset ALS;
- Any use of non-invasive ventilation (e.g., continuous positive airway pressure, non-invasive bi-level positive airway pressure or non-invasive volume ventilation) for any portion of the day, or mechanical ventilation via tracheostomy, or on any form of oxygen supplementation;
- Any other significant neurological disorder which can interfere with study assessments, e.g., significant cognitive impairment and/or clinical dementia;
- Significant psychiatric illness like schizophrenia, bipolar disorder etc. Subjects with depression can be included, only if the depression has been stable and no episode of major depression has occurred in past one year;
- Severe cardiac disease (e.g.,corrected QT interval > 500ms), Torsade de Pointes, evidence of significant heart failure (New York Heart Association [NYHA] Class 3 or greater, myocardial infarction or unstable angina in the 6 months prior to screening);
- Any moderate-to-severe pulmonary disease or difficulty taking inhaled drugs;
- Inability to tolerate the administration of an oral inhaled powder via dry powder inhaler (DPI);
- Has taken any investigational study drug within 30 days or five half-lives of the drug, whichever is longer, prior to dosing;
- Currently taking cromolyn, or has taken cromolyn, within the past 12 months;
- Allergy to cromolyn or cromolyn products, such as Intal®, Nasalcrom®, Opticrom®, Gastrocrom®, etc.;
- Taking inhaled protein products on a chronic basis (such as insulin, parathyroid hormone [PTH], etc.);
- Subjects who weigh 88 lb (40 kg) or less, or, body mass index (BMI) of <17.5 or >35.0 at screening;
- Moderate-to-severe liver disease: aspartate aminotransferase (AST), alanine aminotransferase (ALT), or bilirubin concentrations >3 times the upper limit of normal; patients with hepatic diseases such as hepatic cirrhosis, hepatic cancer and active hepatitis
- Moderate-to-severe renal disease: creatinine clearance <45 mL/min/1.73 m2 (by Cockcroft-Gault calculation);
- Any clinically significant disorder or laboratory abnormality that, in the investigator's opinion, could interfere with the subject's participation in the study, place the subject at increased risk, or confound interpretation of the study results;
- Pregnant or breast-feeding females or sexually active females with childbearing potential, if no adequate contraceptive measures are used.
