A Study to Evaluate the Pharmacokinetics and Food-effect of IN-M00002 Tablet in Healthy Adult Volunteers

A randomized, open-label, crossover study

[Part A] To evaluate and compare the pharmacokinetic and safety of co-administration of tegoprazan and naproxen versus administration of IN-M00002 tablet in healthy adult volunteers

[Part B] To evaluate the effects of food on the pharmacokinetic and safety of IN-M00002 tablet in healthy adult volunteers

• ALT or AST value > twice the upper limit of normal (ULN)
• History of periodic alcohol consumption exceeding 210 g/week within 6 months prior to screening (beer (5%) 1 glass (250 mL) = 10 g, soju (20%) 1 glass (50 mL) = 8 g, wine (12%) 1 glass (125 mL) = 12 g)
• Has taken any other investigational product within 6 months prior to the first dose of investigational product
• History of serious alcohol or drug misuse and abuse within 1 year prior to screening

• Daily use of ≥ 20 cigarettes within 6 months prior to screening
• Administration of a prescription or non-prescription drug within 10 days prior to the first dose of the investigational product
• Whole blood donation within 2 months prior to the first dose of the investigational product or apheresis donation within 1 month prior to the first dose of the investigational product
• Subjects who received a blood transfusion within 1 month prior to the first dose of the investigational product
• Those who may be put at an increased risk due to the administration of the investigational product and study participation or have a severe acute/chronic medical or mental condition which may interfere with the interpretation of study results
• Subjects with a history of hypersensitivity (e.g., asthma, rhinitis, nasal polyps, urticaria, or allergic reactions) to the components of tegoprazan or naproxen, benzimidazole derivatives, aspirin, or other non-steroidal anti-inflammatory drugs (including COX-2 inhibitors)
• Subjects currently receiving medications containing atazanavir, nelfinavir, or rilpivirine
• Women with a positive pregnancy test, pregnant, or breastfeeding
