Medications: • Allergy to naproxen, acetylsalicylic acid or other NSAID drug. • Severe naproxen intolerance in the past. • No intra-articular injections in the 28 days prior to screening. • Use of a second NSAID including aspirin within 14 days prior to baseline endoscopy, or planned use during study participation. • Use of an anti-coagulant or anti-platelet drug within 14 days prior to baseline endoscopy or planned use during study participation. • Use of proton-pump inhibitors (PPI), type 2 histamine blockers (H2 blocker), antacids, binding agents including bile acid sequestrants, pancreatic replacement, cholinesterase inhibitors or specified analgesics including narcotics within 14 days prior to baseline endoscopy or planned use during study participation. • Treatment with an investigational agent (including device) within 28 days or 5 investigational drug half-lives (whichever is longer) of Screening, current participation in another research study, or participation in more than 3 research studies in the previous 12 months. Screening Laboratory Tests: • Positive H. pylori stool antigen test • Hgb 1.5 times upper limit of normal. • Positive hepatitis B surface antigen (HBsAg). • Positive anti-hepatitis C (HCV) IgG antibody. • Positive anti-human immunodeficiency virus (HIV) 1/2 IgG antibody.

Design outcomes

Primary

MeasureTime frame
Secondary Objective: Exploratory (for Arm A vs B): 1. To compare changes in stiffness, function and total response in an index osteoarthritic knee joint 2. To evaluate GI and overall safety of LT-NS001 1200 mg versus Naprosyn® 500 mg b.i.d. for 12 weeks 3. To develop population PK data for analysis of covariates;Primary end point(s): Primary (GI Safety): Cumulative incidence of patients with gastric ulcer by endoscopy at week 12 for Arm A versus Arm B;Main Objective: Primary (GI Safety): To compare the cumulative incidence of patients with gastric ulcer by endoscopy (EGD) for Arm A vs Arm B Secondary (for Arm A vs Arm B): 1. To demonstrate non-inferior pain control in an index osteoarthritic knee joint 2. To compare overall gastric injury rates by EGD 3. To compare tolerability and retention on study drug
