Arms and Interventions

Arm Intervention/Treatment
Experimental: NX-13 250mg

Subjects will take study drug by ingesting three tablets per day, recommended at the same time daily for consistency. Subjects in a NX-13 group will receive either 250 mg or 750 mg of NX-13 in 3 tablets and subjects in the placebo group will receive matching placebo.

Drug: NX-13 250mg
NX-13 250mg tablet, plus 2 placebo tablets

Experimental: NX-13 750mg

Subjects will take study drug by ingesting three tablets per day, recommended at the same time daily for consistency. Subjects in a NX-13 group will receive either 250 mg or 750 mg of NX-13 in 3 tablets and subjects in the placebo group will receive matching placebo.

Drug: NX-13 750mg
NX-13 250mg tablets times 3 to equal 750mg

Placebo Comparator: NX-13 Placebo

Subjects will take study drug by ingesting three tablets per day, recommended at the same time daily for consistency. Subjects in a NX-13 group will receive either 250 mg or 750 mg of NX-13 in 3 tablets and subjects in the placebo group will receive matching placebo.

Drug: NX-13 Placebo
NX-13 Placebo tablets times 3 for blinding purposes

Outcome Measures

Primary Outcome Measures

  1. To assess the clinical activity of oral NX-13 vs placebo [365 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

  1. Safety and Tolerability-AE/SAE - Hematology [365 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.

  2. Safety and Tolerability-AE/SAE - Chemistry [365 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.

  3. Safety and Tolerability-AE/SAE - Vital Signs [365 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).
