"In the first half of 2021, the Seelos team continued to execute at a very high level. Part 1 of the SLS-002 study demonstrated rapid antidepressant and anti-suicidal effects with a well-tolerated safety profile. We have begun the placebo-controlled Part 2 of this registration directed study and plan to enroll in up to 30 sites," said Raj Mehra Ph.D., Chairman and CEO of Seelos. "The SLS-005 IV trehalose program's pivotal study in ALS, which was accepted into the HEALEY ALS Platform Trial at Harvard, plans to commence dosing patients in the third quarter as well. We have begun additional in vivo studies with our gene therapy program SLS-004 after demonstrating its capability of reducing alpha-synuclein expression targeting Parkinson's disease, and we continue to evaluate additional indications for both SLS-002 and SLS-005."

In the first half of 2021, Seelos achieved several major clinical and financial milestones and continued to make progress on its multiple clinical stage development programs.

In April, Seelos announced a Strategic Device Partnership with AptarGroup, Inc. for the co-exclusive use and supply of Aptar Pharma's Bidose (BDS) Liquid System device for SLS-002 in the investigational development programs for the treatment of suicidality, depression, and Post-Traumatic Stress Disorder (PTSD) and under the terms of the agreement, Seelos has certain rights to add other undisclosed indications to the Strategic Device Partnership.
