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 its year-end 2021 business and clinical update.
"In the second half of 2021, we continued to accomplish several significant milestones and continued to execute in the face of one of the most difficult environments for publicly-traded biotech companies that I've seen in my career," said Raj Mehra Ph.D., Chairman and CEO of Seelos. "We began the placebo-controlled Part 2 of the registration directed study of SLS-002 and plan to enroll in over 30 sites. The SLS-005 IV trehalose program's registrational study in ALS, which was accepted into the HEALEY ALS Platform Trial at Harvard, commenced dosing participants in February 2022 and our IND was accepted to study SLS-005 in spinocerebellar ataxia and its Phase IIb/III pivotal study should begin dosing in Q2 2022. We have begun additional in vivo studies with our Parkinson's disease focused gene therapy program SLS-004 after demonstrating its capability of reducing alpha-synuclein expression. We look forward to continuing to provide meaningful updates on the current state of progress on all of our programs as well as additional initiatives."
Seelos Clinical Update
SLS-002 (intranasal racemic ketamine)
- In July, Seelos began dosing patients in Part 2 of the registration directed, double-blind, placebo-controlled cohort in Acute Suicidal Ideation and Behavior (ASIB) in patients with Major Depressive Disorder (MDD).
- In June, based on feedback from a Type C meeting with the FDA, Seelos is planning to expand the size of the trial and number of sites now that this trial has been labeled registration directed.
- In October, Seelos presented a poster titled " A Phase 2 Open Label Study of Efficacy, Safety, and Tolerability of SLS-002 (Intranasal Racemic Ketamine) in Adults with Major Depressive Disorder at Imminent Risk of Suicide ", at the 2021 IASR/AFSP International Summit on Suicide Research Virtual Conference. SLS-002 demonstrated rapid, robust and sustained reductions on the Montgomery-Åsberg Depression Rating Scale (MADRS), the Clinical Global Impression of Severity for Suicidal Ideation and Behavior, the Patient Global Impression of severity for Suicidal Ideation and Behavior, and the Sheehan-Suicidality Tracking Scale. Additionally, the group mean met the MADRS remission criteria initially on day 6 after only 2 doses of SLS-002.
SLS-005 (IV Trehalose)
- In November, the FDA accepted Seelos' Investigational New Drug (IND) application to study SLS-005 for the treatment of spinocerebellar ataxia (SCA). Seelos plans to initiate a Phase IIb/III registrational study in the first half of 2022.
- The FDA granted the program Fast Track designation in the U.S. for SCA, and SLS-005 has previously received Orphan Drug designation for spinocerebellar ataxia type 3 (SCA3) from the FDA and from the European Medicines Agency in the EU.
- Also in November, Seelos was an Emerald Sponsor of the 4 th Annual ALS ONE Research Symposium where Dr. Mehra presented an update of the program.
- In February 2022 , Seelos commenced dosing of the first participants in a registrational Phase II/III trial in amyotrophic lateral sclerosis (ALS) as part of the HEALEY ALS Platform Trial led by Harvard Medical School at Massachusetts General Hospital at several dozen trial sites across the U.S.
SLS-004 and SLS-007 (Parkinson's disease gene therapy programs)
- In early July, Seelos released in vivo data demonstrating down-regulation of SNCA mRNA and protein-expression from a study of SLS-004 in an in-vivo rodent model utilizing CRISPR-dCas9 gene therapy technology.
- Additional studies have commenced to explore efficacy of SLS-004 in the induced Parkinsonism in an in-vivo rodent model.
- Seelos was issued a patent covering the composition of matter for SLS-007, a potentially disease-modifying gene therapy focused on intracellular alpha-synuclein (α-synuclein) aggregation in Parkinson's disease (PD).
Seelos Business Update
- In the second half of 2021, Seelos achieved several major clinical and financial milestones and continued to make progress on its multiple clinical stage development programs.
