Autobahn Therapeutics Announces Presentation of ABX-002 Phase 1 Clinical Results at the 2025 ASCP Annual Meeting

Poster presentation to highlight Phase 1 results that support ABX-002 Phase 2 development as an adjunctive treatment for major depressive disorder and bipolar disorder depression

SAN DIEGO--(BUSINESS WIRE)--Autobahn Therapeutics, a biotechnology company developing restorative treatments for people affected by neuropsychiatric and neuroimmunologic disorders, today announced the company will present the clinical results from its completed Phase 1 trial of ABX-002 at the 2025 American Society of Clinical Psychopharmacology (ASCP) Annual Meeting, taking place May 27-30, 2025, in Scottsdale, AZ. ABX-002 is a highly potent, oral, thyroid hormone beta receptor (TRβ) selective agonist designed to enhance the CNS benefits of thyroid hormone biology for patients suffering from major depressive disorder (MDD), bipolar disorder depression, and other affective illnesses.



“We are excited to share the Phase 1 findings at ASCP, which demonstrated a favorable safety and tolerability profile and enhanced CNS target engagement with ABX-002, and support its evaluation in the ongoing Phase 2 trials in major depressive disorder and bipolar depression,” said Gudarz Davar, M.D., Executive Vice President, Head of Research and Development for Autobahn. “Despite availability of existing therapies, many individuals with MDD and bipolar depression struggle to achieve adequate relief. Our team remains deeply committed to developing novel, CNS-targeted treatments that we believe have the potential to meaningfully improve the lives of those affected by these debilitating conditions.”

Results from the completed Phase 1 trial of ABX-002 in healthy volunteers demonstrated ABX-002 was safe and well tolerated, with no serious adverse events observed. Additionally, ABX-002 demonstrated dose proportional PK and clinical evidence of CNS target engagement consistent with brain-activating thyroid effects, helping inform Phase 2 dose selection. The company is currently evaluating ABX-002 as a potential adjunctive treatment for people with major depressive disorder in the ongoing AMPLIFY Phase 2 trial and as a potential adjunctive treatment for bipolar depression in a separate ongoing Phase 2 trial.

About ABX-002
ABX-002 is an orally administered, potent and selective thyroid hormone beta receptor (TRβ) agonist designed to enhance the CNS benefits of thyroid hormone biology while also reducing the peripheral liabilities of synthetic thyroid hormone (e.g., triiodothyronine, T3), a treatment which has shown efficacy in numerous placebo-controlled human studies across MDD and bipolar disorder depression. Thyroid hormone agonism has demonstrated activity on cellular energy metabolism pathways, which play an important role on the regulation of brain bioenergetics and may be uniquely suited to address symptoms of atypical depression, a highly prevalent and underserved sub-population of MDD. In nonclinical and clinical studies, ABX-002 has demonstrated optimized PK properties, target engagement in brain regions associated with depression, and an attractive safety and tolerability profile.
