Proteomics Produces Predictive Test for Diagnosis of Diabetic Kidney Disease

ASX Media Release, 9 June 2015

Life sciences company Proteomics International Laboratories (ASX: PIQ) is pleased to announce that it has produced and validated a predictive test for the diagnosis of diabetic kidney disease (DKD).

The test, called PromarkerD, is the world’s first proteomics-derived predictive (prognostic) test for the diagnosis of DKD, and represents a global breakthrough in the diagnosis and treatment of the disease.

There is currently no available test for predicting the onset of DKD.

The potential global medical benefits and cost savings from PIQ’s predictive test are huge. Diabetes is the fastest growing health issue in the world today and is the largest cause of kidney disease – for example, 35% of adults in the USA with diabetes have chronic kidney disease.

The ability to accurately predict the onset of DKD via a simple blood test and then provide appropriate clinical treatment to prevent the onset of the disease has the potential to save health care systems globally billions of dollars. In Australia alone, the total cost to the health system and in productivity loss attributed to diabetes is estimated at $10.3 billion annually. Of the approximately 1.7 million Australians who have chronic kidney disease, 1.5 million are not aware they have it.

The commercial benefits to PIQ in successfully commercialising the test are enormous. The potential for pharmaceutical companies to market PromarkerD to identify at-risk patient groups and then to provide drugs to manage patients more effectively could provide PIQ with substantial returns in the form of licensing fees and royalties.

Background

The test was developed using PIQ’s world-leading proprietary proteomics platform to measure specific biomarkers (biological signatures) in the blood of patients with diabetes to determine the likelihood of those patients contracting DKD. Specifically, PromarkerD simultaneously measures a panel of 2-6 proteins to determine the patient’s disease state.

Applying its mass spectrometry-based proteomics technology, the Company has developed a deeper understanding of DKD beyond classical pathology, by comparing the differences in the protein make- up of people with and without the disease.

Study Results

The test was developed and validated in a $2 million clinical study of 576 patients with diabetes, followed between 2010 and 2014 in Western Australia.

The results show PromarkerD can predict:

• Which patients with diabetes will progress to have a significant decline in kidney function better than any other current known measure; and
• Which people with apparently healthy kidney function as measured by conventional tests are at risk of kidney problems.

Specifically, the clinical study, which is on-going, found that 10% of the patients had a significant and rapid decline in kidney function over the four year study period and that PromarkerD correctly predicted 67% of these individuals.

The samples in the study were cross-validated with an established antibody-based technique broadly accepted by the US Food and Drug administration (FDA), which showed there was excellent correlation between the two methods.

PromarkerD also has a diagnostic component (in addition to its predictive application), which utilises the biomarker panel to diagnose the early onset of DKD in a patient, where current tests for kidney function fail to detect the disease.
