Canagliflozin Lowers PromarkerD DKD Risk Prediction Scores
Perth, May 3, 2023 AEST (ABN Newswire) - Proteomics International Laboratories Ltd (ASX:PIQ) is pleased to announce results showing a significant reduction in the PromarkerD risk scores of patients with type 2 diabetes after taking the diabetes medicine canagliflozin, with the benefit greatest in patients identified as being at high-risk of diabetic kidney disease (DKD). The results were published yesterday as a feature article in the international peer-reviewed Journal of Clinical Medicine.
- Research conducted with Janssen Research & Development looked at PromarkerD results of patients taking diabetes medication canagliflozin
- Study of over 2,000 participants found a significant reduction in the PromarkerD risk scores for developing diabetic kidney disease in those who took the medication compared to placebo
- Effect was greatest in participants predicted by PromarkerD to be at high-risk of a decline in kidney function at the start of the study
- Research published as a feature article in the peer-reviewed Journal of Clinical Medicine
- Study shows the power of using PromarkerD as a Precision Medicine tool to assist in the treatment and prevention of diabetic kidney disease
The study was conducted as part of a long-running collaboration between Proteomics International and Janssen Research & Development, LLC ("Janssen", the pharmaceutical arm of Johnson & Johnson) (ASX 31 March 2020). Researchers at the two companies examined the association between canagliflozin, an approved diabetes therapy with additional kidney and cardio protective benefits, and changes in PromarkerD scores in people with type 2 diabetes.
Proteomics International Managing Director Dr Richard Lipscombe said the publication demonstrates that gliflozin class drugs can lower PromarkerD risk scores, and have the potential to treat at-risk patients identified by the test. "The findings illustrate the benefits of using PromarkerD testing - it's exciting that we can identify patients who are asymptomatic for diabetic kidney disease but still at high risk of developing the disease, and that canagliflozin significantly lowers their risk of developing diabetic kidney disease. It's an elegant example of using precision medicine to enable early intervention and slow or stop the onset of disease."
The research found the average PromarkerD risk score of patients taking canagliflozin dropped during the trial, while the average risk score of patients taking a placebo rose. The effect was greatest in participants who were identified by PromarkerD to be at high-risk of a decline in kidney function at the start of the study.
PromarkerD is a newly-developed blood test that can predict diabetic kidney disease before clinical symptoms appear, helping doctors make treatment decisions and improving outcomes for patients with type 2 diabetes.
Canagliflozin is an SGLT2-inhibitor drug used in the treatment of diabetes. It was the first diabetes medicine with an indication to slow the progression of diabetic kidney disease in patients with type 2 diabetes and DKD (FDA 27 Sept 2019). The gliflozin class of drugs is widely used to treat patients with type 2 diabetes.
The study examined blood samples from patients in Janssen's completed CANagliflozin cardioVascular Assessment Study (CANVAS) clinical trial. The research team retrospectively measured PromarkerD scores in samples from 2,008 patients taken at the start of the trial and again three years later. Janssen providedthe samples and Proteomics International tested them using PromarkerD. The publication follows an in depth joint analysis of the study results by the two research teams, and comprehensive peer review, and builds upon preliminary results first presented at the Australasian Diabetes Conference (ASX 12 August 2021).

Summary of Study
Aim: To examine whether the diabetes drug canagliflozin (an SGLT2-inhibitor) affected the PromarkerD risk score over a three-year follow-up period in participants with type 2 diabetes.
Method: Retrospective analysis was performed on 2,008 participants (N=629 placebo arm, N=1379 canagliflozin arm) from the completed multinational Canagliflozin cardio-Vascular Assessment Study (CANVAS), a randomized placebo-controlled trial, with preserved kidney function (baseline eGFR >- 60 mL/min/1.73 m2 with any uACR).
PromarkerD scores were calculated at baseline and Year 3 using the previously defined algorithm, and generalized estimating equations were used to assess the effect of canagliflozin versus placebo on PromarkerD scores during the 3-year follow-up period.
Results: After accounting for the known acute drop in eGFR following canagliflozin initiation, there was a significant treatment-by-time interaction (p < 0.001), whereby participants on canagliflozin had decreased mean PromarkerD scores from baseline to Year 3 (Diagnosis score: -1.0%; p = 0.039), while the scores of those on placebo increased over the three-year period (Diagnosis score: 6.4% ; p < 0.001). When stratified into PromarkerD risk categories, participants with high risk scores at baseline who were randomized to canagliflozin had significantly lower scores at Year 3 (Diagnosis score: -5.6%; p < 0.001), while those on placebo retained high scores (Diagnosis score: 4.5% ; p = 0.035) (See Figure*).
Conclusions: Previous studies demonstrated that higher PromarkerD scores are significantly predictive of incident DKD in the next four years in community-based and clinical trial participants with type 2 diabetes.
- In the present study, canagliflozin significantly decreased mean PromarkerD scores compared to placebo over three years, with the effect greatest for those classified using PromarkerD as at high risk of a subsequent decline in kidney function at the outset.
- In contrast, PromarkerD scores for participants on placebo significantly increased during the three years.
- It follows that a decrease in PromarkerD scores is associated with a lower risk of future DKD, as well as longer term beneficial kidney and cardiovascular disease outcomes.
Patient risk stratification with PromarkerD allows a more informed approach to management of those at highest risk of developing DKD.
About PromarkerD (www.PromarkerD.com)
Diabetic kidney disease (DKD) is a serious complication arising from diabetes which if unchecked can lead to dialysis or kidney transplant. PromarkerD is a prognostic test that can predict future kidney function decline in patients with type 2 diabetes and no existing DKD. The patented PromarkerD test system uses a simple blood test to detect a unique 'fingerprint' of the early onset of the disease by measuring three serum protein biomarkers, combined with three routinely available conventional clinical variables (age, HDLcholesterol and estimated glomerular filtration rate (eGFR)). A cloud based algorithm integrates the results into a patient risk report classifying individuals as high, medium or low risk of developing DKD. In clinical studies published in leading journals PromarkerD correctly predicted up to 86% of otherwise healthy diabetics who went on to develop diabetic kidney disease within four years. The PromarkerD test is available in the USA as a Laboratory Developed Test (LDT), is pending approval from the TGA in Australia, and is CE Mark registered in the European Union.
