The poster #851112 entitled, "Pharmacological and Toxicological Evaluation of AEZS-130/Ghrelin Receptor Agonist, a Novel, Oral Synthetic Growth Hormone Secretagogue for the Diagnosis of Growth Hormone Deficiency", Babette Aicher,
The ability of AEZS-130 to increase growth hormone levels after repeated oral treatment of five days was demonstrated in beagle dogs, showing a 4-10 fold increase in the area under the curve of growth hormone levels. The fact that the growth hormone secretagogue effect was maintained after repeated dosing paves the way for the future therapeutic use of this compound. Safety of AEZS-130 was shown in various early safety and toxicity assays in vitro, as well as in preclinical safety and toxicity studies in rats and dogs.
Juergen Engel, Ph.D., President and CEO of Aeterna Zentaris stated, "We are very pleased with these preclinical data which confirm AEZS-130's safety as well as its potential, both as a diagnostic test and a therapeutic agent for growth hormone deficiencies. We now look forward to successfully completing our current Phase 3 registration trial with this compound as a diagnostic test for growth hormone deficiency in adults, and the possible subsequent NDA filing in the U.S. for this indication."
A copy of the abstract is currently available on the ENDO website at www.endo-society.org.
AEZS-130 is a novel, oral growth hormone secretagogue (GHS) which exerts its effect by binding to the growth hormone secretagogue receptor GHS-R1A, which is the receptor for the physiological peptide ligand ghrelin. This mechanism of action was determined previously by binding studies assessing the affinity for the GHS-R1A by using membrane preparations from human pituitary gland, as well as transiently expressing LLC-PK1 cells (Ref. 1). AEZS-130 is currently in a Phase 3 trial as a diagnostic test for GH deficiency in adults.
