NEW YORK--(BUSINESS WIRE)--Retrophin, Inc. (OTCQB: RTRX) today announced its newest clinical development candidate RE-034 (cosyntropin), a long-acting synthetic analog (amino acids 1-24) of the naturally-occurring adrenocorticotropic hormone (ACTH) formulated with zinc. Cosyntropin is also known outside the U.S. as tetracosactide.
 
"We expect that physicians would welcome the potential benefits and consistency of our compound, as synthetic medicines are often preferable to animal-derived drugs."
 
Retrophin plans to file an Investigational New Drug (IND) Application and initiate a Phase 1 pharmacokinetic trial of RE-034 in the first half of 2014. Shortly thereafter, the company plans to initiate Phase 3 pivotal clinical trials of RE-034 for the treatment of infantile spasms, or West Syndrome, a catastrophic form of epilepsy, and nephrotic syndrome, a devastating condition marked by very high levels of proteinuria. Commercially available ACTH formulations that are substantially similar to RE-034 have been shown to be efficacious in treating these diseases. Retrophin recently met with the U.S. Food and Drug Administration (FDA) and agreed with the FDA on a clinical trial design for approval in West Syndrome.
 
"Melanocortin agonists have shown profound activity in nephrology and neurology," said Martin Shkreli, Founder and Chief Executive Officer of Retrophin. "These are two key therapeutic areas for Retrophin, so approximately a year ago we embarked on development of RE-034 and have recently reached major CMC milestones. Our planned robust clinical trials will add to the understanding of this class of compounds, and we look forward to exploring RE-034 as a treatment for additional grave diseases. Furthermore, our synthetic ACTH can potentially bring relief to the high cost burden associated with the currently available animal-derived formulation in the U.S."
 
"This is promising news for patients who suffer from nephrotic syndrome and infantile spasms, two very serious conditions," said Horacio Plotkin, M.D., Chief Medical Officer of Retrophin. "We expect that physicians would welcome the potential benefits and consistency of our compound, as synthetic medicines are often preferable to animal-derived drugs."
