Exclusion criteria

• {"criterion_text":"- ALSFRS-R score change (decrease) by 2.5 or more points between the Screening and Day 1 (baseline) score.\n- Taking inhaled protein products on a chronic basis (such as insulin, parathyroid hormone [PTH], etc).\n- Subjects with a body weight of 32 kg or less, or a body mass index (BMI) of <17.5 or >35.0 at time of screening.\n- Moderate-to-severe liver disease: aspartate aminotransferase (AST), alanine aminotransferase (ALT) >3 times the upper limit of normal; total bilirubin >1.5 x ULN ; subjects with hepatic diseases such as hepatic cirrhosis, hepatic cancer and active hepatitis.\n- Moderate-to-severe renal disease: creatinine clearance <45 mL/min/1.73 m2 (by Cockcroft- Gault calculation).\n- Any CS 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\n- Pregnant or breast-feeding females.\n- Bulbar onset ALS (<9 bulbar subscore).\n- 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.\n- Any other significant neurological disorder which can interfere with study assessments, e.g., significant cognitive impairment and/or clinical dementia.\n- 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 the past year.\n- Severe cardiac disease (e.g., QTc>500 ms), 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).\n- Any moderate-to-severe pulmonary disease or difficulty taking inhaled drugs.\n- Inability to tolerate the administration of an oral inhaled powder via DPI.\n- Has taken any investigational product (IP) within 30 days or 5 half-lives of the drug, whichever is longer, prior to dosing."}
