Clinical Trial Summary

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.

Description:

This Phase IIa study is designed as a randomized, open-label, multi-center, multi-dose study for subjects with mild to moderate ALS. The study will evaluate 1) safety, 2) tolerability, 3) changes in physical function measured using the ALSFRS-R, 4) two doses of ALZT-OP1a in order to determine an optimal and effective dose that could positively impact neuro-inflammatory biomarkers, and 5) to demonstrate preliminary evidence if this treatment could potentially slow down or arrest functional decline in subjects with mild to moderate ALS.

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.

• 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.
