Praetego is a preclinical stage pharmaceutical company committed to addressing serious diabetic complications. Our novel and proprietary small molecule candidates target a common pathway in disease progression leading to serious complications.

Our first target is Diabetic Peripheral Neuropathy (DPN)—a degenerative process of the nerves in the extremities. DPN affects approximately 50% of patients living with diabetes. Our candidates may also address other diabetic complications such as cognitive decline, nephropathy and retinopathy.

1. Amadorins

The Amadorins are unique inhibitors of the oxidative breakdown of proteins modified by glucose (Amadori products).

This non-enzymatic process forms byproducts called Advanced Glycation End-products, or AGEs. AGE formation and accumulation leads to damage of the small blood vessels that supply vital nutrients to the eyes and the kidneys, as well as the nerves that enervate the extremities. This mechanism of damage is present across the spectrum of serious diabetic complications as well as cardiovascular disease and neurodegeneration.

The Amadorins, developed through a proprietary assay, inhibit AGE formation at its earliest stages. By interrupting the cascade at the first step of oxidative breakdown, Amadorins offer the greatest promise of protection against serious diabetic complications. As we optimized our candidates for future clinical utility, we improved potency, safety, and pharmacological properties.

For the millions of people living with diabetes, the Amadorins were developed to halt disease progression, rather than manage symptoms.

2. Development Programs

Diabetic Peripheral Neuropathy (DPN)

DPN is the damage that effects the nerves in the hands and feet of diabetics. About 50% of diabetics develop DPN. For many it eventually causes pain. Praetego’s Amadorins target the cause of the damage.

In a proof of concept study using a standard animal model of DPN, the Amadorins restored nerve function. They reversed nerve deficits in both large and small nerve fibers. Over the series of Amadorins tested, we confirmed that stronger AGE inhibition meant greater potency in the preclinical model of diabetic peripheral neuropathy. In preclinical safety studies, the Amadorins demonstrated a wide therapeutic window and minimal off-target hits.

Our most recent drug development work is funded by the National Institute of Diabetic and Digestive and Kidney Diseases.

Other Serious Diabetic Complications

Beyond DPN, we are targeting Cognitive Decline, Nephropathy (Chronic Kidney Disease) and other serious diabetic complications.
