Primary Outcome Measures
NameTimeMethod
To assess the clinical activity of oral NX-13 vs placebo365 days

Change from baseline in mean Modified Mayo Score (MMS) vs placebo. Total score Modified Mayo score 0-9, with higher scores representing more severe disease activity.

Secondary Outcome Measures
NameTimeMethod
Safety and Tolerability-AE/SAE - Hematology365 days

Treatment Emergent Adverse Event/Serious Adverse Event (TEAEs/SAEs) related to hematology. Assessment will be made by summarizing the percentage of subjects with changes from baseline through routine hematology panel (white blood cells, red blood cells, Hemoglobin, Hematocrit, and platelets). All biomarkers are exploratory objectives.

Safety and Tolerability-AE/SAE - Chemistry365 days

Treatment Emergent Adverse Event/Serious Adverse Event (TEAEs/SAEs) related to chemistry. Assessment will be made by summarizing the percentage of subjects with changes from baseline through routine chemistry panel (Blood Urea Nitrogren creatinine, Creatine Kinase bilirubin, Aspartate aminotransferase (AST), Alanine transaminase (ALT), Alkaline phosphatase (ALP), Sodium (Na), Potassium (K), Chloride (CL), bicarb, Calcium (CA), Magnesium (MG), Phosphorus, uric acid, total protein, albumin, glucose, Gamma-glutamyl transferase (GGT), total cholesterol, Low-density lipoprotein (LDL), High-density lipoprotein (HDL), and triglycerides) urinalysis, Estimated Glomerular filtration rate (eGFR). All biomarkers are exploratory objectives.

Safety and Tolerability-AE/SAE - Vital Signs365 days

Treatment Emergent Adverse Event/Serious Adverse Event (TEAEs/SAEs) related to vital signs. Assessment will be made by summarizing the percentage of subjects with changes from baseline through (sitting blood pressure, resting heart rate, and temperature). Changes from baseline deemed clinically significant or associates with AEs (heart rate, pulse rate, QRS, QT, and correct QT).
