Seelos' SLS-002 is currently being developed specifically to treat the symptoms of suicidality associated with major depression

Seelos Therapeutics, Inc. (Nasdaq: SEEL), a clinical-stage biopharmaceutical company focused on the development of therapies for central nervous system disorders and rare diseases, today announced that it will participate in two upcoming psychedelic conferences:

• Jefferies Innovation in Mental Health Summit, Psychedelics and New Emerging Treatments, September 22nd in New York City, NY
• Cantor Neurology and Psychiatry Conference, October 6th in San Francisco, CA

Raj Mehra, Ph.D., Chairman and CEO of Seelos, and senior management will participate in fireside chats, presentations and 1x1 meetings at these upcoming events to discuss the ongoing registrational, double-blind, placebo-controlled study of SLS-002 (intranasal racemic ketamine) for Acute Suicidal Ideation and Behavior (ASIB) in patients with Major Depressive Disorder (MDD).

"SLS-002 is currently being developed specifically to treat the symptoms of suicidality and is currently, we believe, the only drug in this class that is enrolling in a registrational clinical study to measure its effect on patients with acute suicidality in MDD. Suicides and suicide attempts claim far too many lives in the U.S. and globally and are devastating to loved ones. Still, there remains a dire need for a therapeutic labeled to treat the symptoms of suicidality," said Raj Mehra Ph.D., Chairman and CEO of Seelos. "We find it highly encouraging to see the level of interest and acceptance of the psychedelic class of drugs being studied to treat patients suffering with mental health issues and Seelos is proud to be at the forefront of this exciting new therapeutic class."

If you or a loved one are having thoughts of suicide, please seek immediate medical help, go to your nearest emergency room, or call the Suicide and Crisis Lifeline at 988 or 1-800-273-8255 (TALK).

SLS-002 is intranasal racemic ketamine with two investigational new drug applications for the treatment of Acute Suicidal Ideation and Behavior in Major Depressive Disorder or Post-Traumatic Stress Disorder. SLS-002 was originally derived from a Javelin Pharmaceuticals, Inc./Hospira, Inc. program with 16 clinical studies involving approximately 500 subjects. SLS-002 looks to address an unmet need for a therapy to treat suicidality in the U.S. Traditionally, anti-depressants have been used in this setting but many of the existing treatments are known to contribute to an increased risk of suicidal thoughts in some circumstances, and if they are effective, it often takes weeks for the full therapeutic effect to be manifested. The clinical development program for SLS-002 includes two parallel healthy volunteer studies (Phase I) and is being followed by pivotal registration studies after meeting with the FDA. Based on information gathered from the databases of the Agency for Healthcare Research and Quality, there were more than 1,000,000 visits to emergency rooms for suicide attempts in 2019 in the U.S. alone. Experimental studies suggest ketamine has the potential to be a rapid, effective treatment for depression and suicidality.
