Atai and Beckley Report Promising Results for Depression Treatment, Advance to Phase 3 Trials
July 1, 2025
Over the eight-week trial, all primary and key secondary efficacy endpoints were achieved, indicating significant reductions in depressive symptoms.
Atai Life Sciences and Beckley Psytech have announced positive topline results from their Phase 2b study on BPL-003, a treatment for patients with treatment-resistant depression.
The trial demonstrated a statistically significant average decline of 11.1 points in the Montgomery-Åsberg Depression Rating Scale (MADRS) at Day 29 for the 12 mg dose, compared to a 5.8 point reduction in the 0.3 mg comparator group.
BPL-003 was well-tolerated, with 99% of treatment-emergent adverse events classified as mild or moderate, and no serious drug-related adverse events reported.
Most patients were ready for discharge just 90 minutes after receiving treatment, suggesting compatibility with current two-hour in-clinic protocols.
Based on the encouraging results, Atai and Beckley Psytech plan to advance the 8 mg dose of BPL-003 into Phase 3 clinical development, pending regulatory consultation.
This Phase 2b study is notable for being the largest controlled study of mebufotenin to date, enrolling 193 patients across 38 sites in six countries.
The success of this trial raises hopes for psychedelic therapies amid a shifting regulatory climate in the U.S., bolstered by bipartisan support and key appointments under health secretary Robert F. Kennedy, Jr.
The strategic partnership between Atai Life Sciences and Beckley Psytech aims to establish a leading global position in psychedelic-based mental health therapies and is progressing towards shareholder approval.
The positive results from this trial fulfill success criteria for the strategic merger between Atai and Beckley Psytech, allowing the merger to move forward.
In related news, Atai Life Sciences announced a private placement of 18.3 million shares, raising approximately $50 million, which positively impacted the company's stock price.
As interest in psychedelic treatments grows, companies like Beckley Psytech and Atai Life Sciences are competing to bring these innovative therapies to market.
