Clinical Trial Summary

Evaluation of safety, tolerability and superiority of RK-01, a valsartan plus celecoxib dual add-on to metformin-HCL XR over metformin in newly diagnosed and obese adult type 2 diabetes patients with high blood pressure, arthritis and inadequate glycemic control with metformin monotherapy, diet and exercise over 26 weeks of treatment. Objective: To assess effect of RK-01 on HbA1c levels, beta cell function and insulin resistance with co-administration of valsartan, celecoxib and metformin-HCl XR relative to metformin monotherapy. Hypothesis: After 26 weeks of treatment with valsartan, celecoxib and metformin-HCl XR provides greater improvements in glycemic, inflammatory and atherogenic parameters compared to metformin monotherapy.

Description:

PRIMARY: In patients with type 2 diabetes with inadequate glycemic control with metformin monotherapy: Objective: To assess effect of RK-01 on HbA1c levels, beta cell function and insulin resistance with co-administration of valsartan, celecoxib and metformin-HCl XR relative to metformin monotherapy. Improvements in glycemic, inflammatory and atherogenic parameters including beta cell function relative to adult healthy volunteers with normal glucose tolerance (NGT) treated with placebo for 26 weeks will also be assessed. An interim study assessment will also be performed after 12 weeks of treatment. Hypothesis: After 26 weeks of treatment with valsartan, celecoxib and metformin-HCl XR provides greater improvements in glycemic, inflammatory and atherogenic parameters compared to metformin monotherapy.

To rule out latent autoimmune diabetes in adults (LADA), screening for other diabetes-related antibodies, such as insulinoma-associated protein (IA-2 and IA-2 beta), zinc transporter-8 (ZnT8), islet cell antibodies (ICA) or insulin autoantibody (IAA) will also be considered.

3. Pregnant women

4. Patients with a history of Ketoacidosis.

5. Subjects at serious risk of gastrointestinal (GI) adverse events (e.g. current or recent history of GI bleeding ulceration, or perforation).

6. Subjects with a planned radiologic study with intravenous contrast, surgery, or other planned procedures that may predispose them to metformin-associated lactic acidosis.

10. eGFR, impaired kidney function < 60 ml/min/1.73m2.

11. Poor metabolizers of Cyp450 2C9 to avoid very high concentration (Since Cytochrome 450 2C9 is responsible for the metabolism of both Valsartan and Celecoxib, patients who are known or suspected to be poor Cyp450 2C9 metabolizers based on previous history will be excluded from the study).

12. Any of the following cardiovascular (CV)/Vascular diseases within 3 months of the

enrollment visit:

1. Myocardial infarction (MI)

24. Abnormal free T4

25. Patients with serious infection

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in glycosylated Hemoglobin (HbA1c) for metformin background patients	Glycosylated hemoglobin (HbA1c) is a measurement of the percentage of hemoglobin that is glycated.
