(OTC: ATXI) (“Avenue” or the “Company”), a specialty pharmaceutical company focused on the development and commercialization of therapies for rare and neurologic diseases, today announced that it has entered into an exclusive worldwide license agreement with Duke University for patents and know-how pertaining to ATX-04 (clenbuterol), a well-characterized small-molecule β2-adrenergic agonist, in clinical development for the treatment of Pompe disease. Pompe disease is a rare, inherited lysosomal storage disorder caused by deficiency of the enzyme acid α-glucosidase (GAA), resulting in progressive skeletal and respiratory muscle weakness. The disease presents across a wide clinical spectrum, from severe infantile-onset to later onset forms marked by progressive muscle weakness and respiratory failure, and remains associated with significant morbidity despite available enzyme replacement therapies (ERT). Clenbuterol is a clinically validated, orally administered selective β2-adrenergic agonist with regulatory approvals outside the United States for the treatment of respiratory diseases. The drug has well-established anabolic effects on skeletal muscle, resulting in increased protein synthesis and muscle fiber size. In addition, clenbuterol enhances lysosomal biogenesis and intracellular trafficking of GAA, the enzyme deficient in Pompe disease, leading to reduced glycogen accumulation in muscle tissue. A clinical study conducted at Duke University in patients with Pompe disease on baseline ERT, led by Principal Investigator Dwight D. Koeberl, M.D., Ph.D., demonstrated that ATX-04 was associated with meaningful improvements across multiple clinically and biologically relevant domains. Treatment with ATX-04 resulted in improvements in six-minute walk distance, re...
