Relmada Therapeutics Announces Notice of Acceptance of Key Patent in Europe Covering NMDA Receptor Antagonist d-Methadone for Treatment of Psychiatric Symptoms

Patent significantly expands Relmada intellectual property protection and positions company to target global commercial opportunities for wide range of psychiatric disorders.

NEW YORK, Jan. 9, 2018 /PRNewswire/ -- Relmada Therapeutics, Inc. (OTCQB: RLMD), a clinical-stage company developing novel therapies for the treatment of central nervous system (CNS) diseases, announced today that the European Patent Office has issued a notice of allowance for patent application number 13773543.7 for "D-methadone for the treatment of psychiatric symptoms." The patent provides broad coverage in Europe for d-Methadone (dextromethadone, REL-1017), a novel N-methyl-D-aspartate (NMDA) receptor antagonist, for the treatment of symptoms associated with a range of psychological and psychiatric disorders including depression, anxiety, fatigue and mood instability.

"The allowance of this key patent significantly strengthens our IP position and the global commercial opportunities in our d-Methadone program," said Sergio Traversa, CEO of Relmada Therapeutics. "We look forward to advancing our current development programs and to working to identify potential new areas of unmet need where d-Methadone can deliver benefits to patients in the years ahead."

The NMDA receptor is a predominant molecular device for controlling synaptic plasticity and memory function and affects the transfer of electrical signals between neurons in the brain and in the spinal column. Based on their mechanism of action, a range of NMDA receptor antagonists (chemicals that deactivate the NMDA receptor) such as d-Methadone are under consideration as potential therapeutic agents for the treatment of many CNS conditions including some psychiatric disorders.    

In April 2017, Relmada announced that the U.S. Food and Drug Administration (FDA) granted Fast Track designation for d-Methadone for the adjunctive treatment of major depressive disorder. The company plans to advance the development program for d-Methadone to a Phase 2a randomized, double-blind, placebo-controlled study. This trial will assess changes in depressive symptoms as well as the safety, tolerability and pharmacokinetics of two dose levels of REL-1017 as a rapid-acting adjunctive treatment in patients affected by major depression.

About dextromethadone (d-Methadone, REL-1017)

Relmada's dextromethadone is being developed as a rapidly acting oral agent for the treatment of depression with the potential to treat an array of additional neurologic disorders. Working through the same brain mechanisms as ketamine, a non-competitive NMDA channel antagonist, but potentially lacking its adverse side effects, dextromethadone is fundamentally differentiated from all currently FDA-approved antidepressants, as well as all atypical antipsychotics used adjunctively. In April 2017, the FDA granted Fast Track designation for dextromethadone for the adjunctive treatment of major depressive disorder.
