Led By Robert Busch, MD
Research Sponsored by ARKAY Therapeutics
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Males and females, Age: >18 to 70 years at the time of screening visit
Patients with inadequate blood glucose control with Metformin defined as a central laboratory glycosylated hemoglobin (HbA1c) >8.0 and <10.5 obtained at the screening visit
Must not have
Patients with a history of Ketoacidosis
Subjects with a planned radiologic study with intravenous contrast, surgery, or other planned procedures that may predispose them to metformin-associated lactic acidosis
Screening 3 weeks
Treatment Varies
Follow Up baseline and 26 weeks
Awards & highlights


This trial is evaluating the 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. The objective is to assess the effect of RK-01 on hemoglobin A1c (HbA1c) levels, beta cell function and insulin resistance with co-administration of valsartan, celecoxib and metformin-HCl X

Who is the study for?
Adults aged 18-70 with newly diagnosed type 2 diabetes, obesity (BMI ≥30), high blood pressure, and arthritis. They must have poor blood glucose control on metformin alone, not be pregnant or breastfeeding, and have no history of severe kidney disease or other major health issues like heart disease or liver problems.Check my eligibility
What is being tested?
The trial is testing RK-01—a combination of valsartan (for blood pressure), celecoxib (for arthritis pain), and an extended-release form of metformin—against just metformin for better control of blood sugar levels in type 2 diabetes over a period of 26 weeks.See study design
What are the potential side effects?
Possible side effects include those related to each medication: valsartan may cause dizziness; celecoxib can increase the risk of stomach ulcers and heart issues; metformin might lead to digestive upset or a rare condition called lactic acidosis.

Eligibility Criteria

Inclusion Criteria

You may be eligible if you check “Yes” for the criteria below
I am between 18 and 70 years old.
My blood sugar control is poor with Metformin, as my HbA1c is between 8.0 and 10.5.
My HbA1c level was over 7.0 when first diagnosed and I haven't taken diabetes medication.
I have high blood sugar levels and symptoms like excessive thirst, urination, or hunger.
I have never taken RAS blocker medications.

Exclusion Criteria

You may be eligible for the trial if you check “No” for criteria below:
I have had ketoacidosis in the past.
I am scheduled for a procedure that could increase my risk of lactic acidosis due to metformin.
I use insulin for my diabetes.
I have had high blood sugar that was hard to control.
I have COPD.
I have complications from diabetes.
I am not a poor metabolizer of Cyp450 2C9.
I have had weight loss surgery in the past.
I am currently dealing with a serious infection.
My kidney function is reduced, with an eGFR below 60.
I am over 70 years old.
