Viking Therapeutics And Kennedy Krieger Institute Sign Collaboration Agreement To Evaluate Novel Thyroid Beta Agonists For X-Linked Adrenoleukodystrophy (X-ALD)

BALTIMORE and SAN DIEGO, Nov. 23, 2015 /PRNewswire/ -- Kennedy Krieger Institute and Viking Therapeutics, Inc. ("Viking") (NASDAQ: VKTX), a clinical-stage biopharmaceutical company focused on the development of novel therapies for metabolic and endocrine disorders, today announced a sponsored research collaboration focused on evaluating the company's novel thyroid beta agonists for the treatment of X-linked adrenoleukodystrophy (X-ALD).  Under terms of the agreement, Kennedy Krieger's X-ALD research scientists will study Viking's proprietary thyroid beta agonists, including VK0214, in in vivo models of X-ALD.

This research will build upon previous cell-based data demonstrating that the company's thyroid beta agonists positively affect the expression of specific genes relevant to X-ALD.  In the planned work, researchers at the Kennedy Krieger will utilize an in vivo X-ALD model to assess the impact of VK0214 on key biomarkers of the disease.  The successful completion of this work will support Viking's initiation of IND-enabling activities with the goal of advancing VK0214 into clinical studies. 

"Collaborating with the Kennedy Krieger Institute is invaluable to the advancement of our thyroid beta agonists as potential treatments for this rare, often fatal, disease," said Brian Lian, Ph.D., chief executive officer of Viking. "The Institute's expertise in X-ALD is unrivalled, and the opportunity to evaluate our compounds in the group's in vivo models will generate critical scientific insight as we advance this program forward.  X-ALD is a debilitating disease for which an adequate treatment is desperately needed.  We're focused on understanding whether our proprietary thyroid agonists hold potential benefits for these patients."

"Scientific research suggests that thyroid beta agonists may play a role in the treatment of X-ALD and we are excited to collaborate with Viking to assess the potential of the company's novel collection of compounds in this area," stated Ali Fatemi, M.D., Director of Neurogenetics and the Moser Center for Leukodystrophies at Kennedy Krieger Institute. "This effort furthers our commitment to improving the lives of individuals with X-ALD, and all those living with disorders of the brain, spinal cord and musculoskeletal system."

Financial terms of the agreement have not been disclosed.

About X-ALD
X-ALD is a rare and often fatal metabolic disorder characterized by a breakdown in the protective barriers surrounding brain and nerve cells; a process known as demyelination.  The disease, for which there is no approved treatment, is caused by mutations in a peroxisomal transporter of very long chain fatty acids (VLCFA), known as ABCD1.  As a result, transporter function is impaired and patients are unable to efficiently metabolize VLCFA.  The resulting accumulation can trigger a rapid, inflammatory demyelination, which leads to cognitive impairment, motor skill deterioration, and even death.  X-ALD is estimated to occur in approximately 1 in 17,000 births.

The thyroid beta receptor is known to regulate expression of an alternative VLCFA transporter, known as ABCD2.  Various preclinical models have demonstrated that increased expression of ABCD2 can lead to normalization of VLCFA metabolism.

About Kennedy Krieger Institute
Internationally recognized for improving the lives of children and adolescents with disorders and injuries of the brain, spinal cord and musculoskeletal system, the Kennedy Krieger Institute in Baltimore, MD, serves more than 20,000 individuals each year through inpatient and outpatient clinics, home and community services and school-based programs. Kennedy Krieger provides a wide range of services for children with developmental concerns mild to severe, and is home to a team of investigators who are contributing to the understanding of how disorders develop while pioneering new interventions and earlier diagnosis.
