Psychedelic Biotechs Approaching Phase 3 Trials for CNS Treatments

The Rise of Psychedelic Biotechs in Mental Health

Psychedelic compounds have been gaining traction in the medical community, inching closer to regulatory approval as pivotal trials focusing on treatment-resistant depression and anxiety progress towards their final stages. This shift marks a departure from the historical countercultural image of psychedelics, as biotech firms evolve serotonergic and psychedelic-derived therapies into mainstream pharmaceutical solutions.

Companies to Watch

Five key players in the industry include Helus Pharma (NASDAQ HELP), AtaiBeckley (NASDAQ ATAI), Definium Therapeutics (NASDAQ DFTX), GH Research (NASDAQ GHRS), and LB Pharmaceuticals (NASDAQ LBRX). These firms are spearheading clinical trials that could reshape treatment standards for mental health disorders.

Helus Pharma

Helus Pharma is at the forefront, presenting a clinical-stage development pipeline targeting depression and anxiety. The company’s innovative approach revolves around novel serotonergic agonists, synthetic molecules engineered to stimulate serotonin pathways, believed to foster neuroplasticity. In a recent pivotal Phase 2 trial published in Nature Medicine, Helus demonstrated significant results. A single 21.5 mg dose of SPL026 led to a mean reduction in MADRS scores, confirming its efficacy in treating major depressive disorder. Notably, response rates reached 35%, outpacing the placebo group.

CEO Michael Cola expressed optimism about Helus’ proprietary compounds, indicating strong potential for consistent, positive outcomes in patients. Currently, Helus is their Phase 2 study for generalized anxiety disorder and advancing their lead asset, HLP003, through pivotal Phase 3 studies.

AtaiBeckley

AtaiBeckley has also made headlines recently, revealing their 2026 pipeline strategy which includes BPL-003, a nasal spray for treatment-resistant depression, which performed well in Phase 2b trials. With positive primary and secondary endpoint results, the company anticipates initiating Phase 3 studies soon. Co-Founder Dr. Srinivas Rao describes 2026 as a pivotal year, emphasizing the newly formed company’s momentum as a result of strategic combinations and redomiciliation to the U.S.

Definium Therapeutics

In January, Definium completed its rebranding from MindMed, shifting focus from a research platform to a late-stage psychiatric company. The lead candidate, DT120, is an LSD-derived tablet that has received FDA Breakthrough Therapy Designation. Definium is poised for three Phase 3 readouts in 2026, illustrating its commitment to advancing psychiatry with psychedelic science.

GH Research

GH Research is another company on the move, recently lifting a clinical hold on its GH001, a proprietary inhaled mebufotenin formulation for treatment-resistant depression. Following success in its Phase 2b trials, GH001 showcases a rapid-onset delivery mechanism, aiming to cater to patients who have difficulty with conventional antidepressants.

LB Pharmaceuticals

Lastly, LB Pharmaceuticals initiated its Phase 2 ILLUMINATE-1 trial of LB-102, targeting bipolar depression. This novel oral antipsychotic focuses on treating mood disorders and could potentially address a significant patient population in the U.S. This aligns with the company's long-term strategy for expanding indications of LB-102 across various psychiatric conditions.

Conclusion

The landscape for psychedelic biotechs is evolving rapidly, presenting a glimpse into a future where innovative treatments could profoundly impact mental health care. As these companies gear up for advanced clinical trials and potential market entries, the coming years could see psychedelics transition firmly into the realm of accepted medical practice. Investors, healthcare professionals, and patients alike are watching with keen interest as the journey unfolds.
