PHILADELPHIA, Oct. 28, 2020 (GLOBE NEWSWIRE) -- Scout Bio, a biotechnology company focused on revolutionizing pet medicine by delivering a pipeline of one-time therapeutics for major chronic pet health conditions, today announced it has initiated two pilot clinical studies to demonstrate effectiveness of an AAV expressing a GLP-1 analog (SB-009) in treating diabetic felines.

Scout Bio envisions two potential therapeutic applications for SB-009. First, to replace daily insulin injections with a single injection of SB-009 to treat feline diabetes and second to significantly increase the percentage of cats entering remission when SB-009 is given with insulin.

The two initiated pilot clinical studies will investigate each of these two potential treatment paradigms.

Mark Heffernan, Ph.D., Chief Executive Officer of Scout Bio remarked, This one-time injectable therapy for feline diabetes has the potential to provide a convenient single treatment that is an alternative to the burden of twice daily insulin injections. We believe SB-009 has the potential to be a blockbuster product for animal health and that our pipeline of gene therapy products for pets will disrupt and grow major markets.

SB-009 was developed under a collaboration between scientists at Scout Bio and the University of Pennsylvanias Gene Therapy Program, where the protein was engineered to improve potency, circulating accumulation kinetics and manufacturability. The design of SB-009 makes the clinical dose both affordable and commercially attractive.

Matthew Wilson, VP Product Discovery and External Innovation said, This is a further example of our strong collaborative relationship with UPenns Gene Therapy Program and Scouts internal capabilities of executing preclinical research to rapidly identify highly potent AAV gene therapies. In less than 12 months after initiating a discovery program, we are now in a position to transition into patients.

Scout Bio has conducted robust preclinical studies with various GLP-1 constructs in rodents and healthy cats. Key findings include:

Dr. Anne Traas, Scout Bios Chief Development Officer reflected, Owners can be devastated to learn their pet has this life-threatening disease and unfortunately, many are unable to give twice daily insulin injections and have to make the difficult choice to euthanize their beloved pet. A one-time safe and efficacious therapy, given by a veterinarian, that eliminates the need for insulin and worry of hypoglycemia, would greatly improve the current treatment paradigm and result in an improved quality of life for diabetic cats and their owners.

Feline diabetes, a severe disease lacking recent innovation, remains a major challenge for veterinarians and owners to safely and effectively manage. Diabetes in most cats is similar to type 2 diabetes in people. Insulin resistance, caused by factors such as obesity, leads to Beta-cell disfunction (the cells that produce insulin). Cats become insulin dependent when blood sugar levels rise, commonly 3-10 times normal, leading to the development of clinical signs which can seriously and negatively impact both the owner and the cat. The most common signs are increased drinking, increased urination and weight loss despite ravenous appetite.

About SB-009 SB-009 is a recombinant AAV gene therapy viral vector utilizing a novel capsid expressing an engineered feline GLP-1 agonist for the treatment of feline diabetes. GLP-1 has been shown to be a safe and highly efficacious molecule in the treatment of humans with type 2 diabetes and SB-009 is the first gene-therapy delivered GLP-1 to be studied in clinical studies in cats with a view to treat the disease.

The expressed feline GLP-1 analog protein functions by stimulating the beta-cells in the pancreas to produce more insulin and may also have an effect in decreasing insulin resistance. GLP-1 receptor agonists do not decrease glucose levels in animals with normal blood glucose, so there is expected to be a very low, or no risk of hypoglycemia.

About Feline DiabetesMost diabetic cats appear to have disease similar to human type 2 diabetes, which is primarily defined as a combined problem with insulin production by the beta-cells in the pancreas, as well as a decrease in the sensitivity to the normal action of insulin (insulin resistance). In cats, one of the most common factors contributing to insulin resistance is obesity which reduces insulin sensitivity.

Lack of insulin production and decreased sensitivity to insulin causes the glucose (sugar) in the blood to become very high leading to the clinical signs. Very high levels of blood glucose also hurt the beta-cells in the pancreas, leading to further reductions in insulin production.

Substantial progress has been made in the treatment of human type 2 diabetes, even in the early stages of the disease. However, insulin therapy remains the only FDA-approved treatment for diabetes in cats.

About Current Treatment | Feline DiabetesCurrent therapy aims to replace the insulin that the cats body no longer makes by injecting insulin twice daily. Giving insulin in the right amounts may bring the blood sugar levels down. If the blood glucose can be brought under control for the majority of a 24-hour period each day, then the clinical signs will be reduced to manageable levels. Too much insulin can cause the blood sugar to drop to dangerous levels (hypoglycemia), so there has to be a careful balance made between maintaining ideal blood glucose levels andadministering too much insulinwhich may result in life threatening low blood sugar levels.

Often owners find the prospect of administering injections to their cats daunting and the strict regimen of twice daily injections and feedings can be difficult to fit into a busy lifestyle. Unfortunately, not treating the cats is simply not a viable option and usually results in a rapid decline in physical health. Even with insulin treatment, some cats diabetes is not well controlled, resulting in the continuation of clinical signs and/or euthanasia.

About Diabetic RemissionGood control of blood glucose may also allow the beta-cells to rest. That rest may increase their capacity to regain some of their insulin-secreting ability. Insulin administration helps to decrease and control the excess blood glucose levels and complement whatever insulin producing ability the cat has left. In some cases, cats regain enough function to allow the insulin injections to stop. This is called diabetic remission. A cat is determined to be in remission when blood sugar is normal and there is complete correction of clinical signs once insulin has been discontinued.
