In 2025, the psychedelic medicine sector reached a more defined phase of maturity, as Big Pharma entry, late-stage clinical readouts, and incremental regulatory shifts began to reshape investor expectations, policy debates, and the direction of research across business, government, and academia.

Business and Investment

Big Pharma joins the sector as key companies push research goals forward 

2025 saw pivotal corporate developments across the major psychedelic medicine companies, uplifting investor expectations and clarifying some regulatory pathways. A slow but steady loosening of regulatory hurdles and positive clinical results have breathed new life into the sector, with some analysts reporting refreshed investor interest and a possible end to the capital drought that has slashed the space in recent years.

Big Pharma giant AbbVie, known for blockbuster drugs in immunology and oncology, agreed to acquire Gilgamesh Pharmaceuticals’ lead experimental therapy, bretisilocin, in a deal reportedly worth $1.2 billion. Bretisilocin is a novel psychedelic targeting major depressive disorder. The event is a signal of Big Pharma entering the space and prioritising shorter-acting serotonin-2A modulators for depression.

Compass Pathways reached a major clinical inflection point, reporting positive results in its first Phase 3 COMP360 trial and accelerating commercial launch planning. CEO Kabir Nath recently told Psychedelic Health that positive talks with the FDA indicate that the company “could potentially be looking at a launch in early 2027” for its flagship program with synthetic psilocybin.

Beckley Psytech, which is supported by Atai Life Sciences secured a Breakthrough Therapy designation by the FDA for BPL-003, a novel intranasal formulation of 5-MeO-DMT, reinforcing regulatory momentum the compound known as “toad venom.” The FDA’s decision follows promising results from a Phase 2b clinical trial, which demonstrated that a single dose of the compound led to rapid and sustained reductions in depressive symptoms within 24 hours, with effects lasting up to eight weeks.

Cybin advanced multiple clinical programs, completing enrollment milestones for CYB004, a version of DMT targeting generalised anxiety disorder and maintaining progress on CYB003, a 5-HT2A receptor agonist similar to psilocybin for major depressive disorder. The company secured financing to extend runway and protect intellectual property across its portfolio.

MindMed reported faster than expected enrollment in its Phase 3 MM120 program, an analog of LSD targeting generalised anxiety disorder, updating timelines for topline readouts and emphasising oral LSD analogs as a differentiated regulatory route. 

Policy and Regulation

Major global players reschedule psychedelics for medical use

2025 marked a year of uneven but consequential movement in psychedelic policy and regulation, with a small number of jurisdictions taking concrete steps toward medical access while others remained in exploratory or preparatory phases.

The UK’s regulatory landscape for psychedelic medicine continued to evolve through policy dialogue and research initiatives, although no formal legalisation or medical scheduling changes occurred. The Royal College of Psychiatrists published a position statement reviewing evidence on psilocybin, MDMA, LSD, and ketamine, concluding that current data are promising but insufficient to recommend routine clinical use outside licensed settings, emphasising the need for more robust trials and caution against premature adoption.

This year, the UK government agreed in principle with key Advisory Council on the Misuse of Drugs (ACMD) recommendations to ease barriers to Schedule 1 psychedelic research. Part of the recommendations included allowing universities and hospitals to conduct research without a Home Office domestic licence, and ethically approved clinical trials to be exempt from additional licensing. Though these changes are not in effect yet, they could be enacted after a pilot program takes place.

Australia continued to stand out as a global pioneer in medical access. Since 1 July 2023, MDMA and psilocybin have been rescheduled from strictly prohibited status to controlled medicines, meaning authorised psychiatrists can legally prescribe them for treatment-resistant depression and post-traumatic stress disorder. From 6 January 2025, new quality standards for MDMA and psilocybin products came into force, requiring compliance for all supplied APIs and finished products. The Department of Veterans’ Affairs approved funding for psychedelic-assisted psychotherapy for eligible veterans, marking a first step toward public payer support.

In Europe, Germany became the first EU country to establish a formal compassionate use access programme for psilocybin, enabling adults with treatment-resistant depression to receive psilocybin therapy at specialised centres under a regulated framework prior to full regulatory approval. This initiative, supported by the German Federal Institute for Drugs and Medical Devices and implemented at facilities in Mannheim and Berlin, marks a landmark step in European psychedelic policy.

The Czech Republic is set to become one of the first European countries to legalise medical use of psilocybin from January 1, 2026. The outgoing government approved legislation late in 2025 allowing psychiatrists and psychotherapists to administer psilocybin for conditions such as cancer-related depression and serious clinical depression when other registered treatments have failed or are not tolerated. Psilocybin therapy will be introduced under controlled clinical conditions at qualified facilities.

In the United States, action remained at the state-level. Oregon and Colorado, having already legalised regulated access to natural psychedelics including psilocybin and launched supervised service programs, continued to refine implementation and data collection frameworks in 2025. Meanwhile, numerous state legislatures introduced bills to advance psychedelic therapy access, and Massachusetts held legislative hearings on psychedelic therapy programmes, reflecting growing political engagement despite the absence of federal reclassification.

Science and Research

New data from real-world applications and feedback from regulatory agencies inform research 

In the academic side of the equation, 2025 consolidated a transition from exploratory efficacy signals to confirmatory, regulation-relevant evidence, while underscoring persistent limitations: small sample biases, variable control conditions, and unresolved questions about long-term safety and scalability.

One of the most significant published findings came from a phase 2 trial in cancer patients, where a single dose of psilocybin combined with therapy produced sustained reductions in depression and anxiety, with many participants maintaining benefits up to two years later. 

Alongside observational outcomes, mid-stage clinical studies have found LSD may ease anxiety symptoms for up to three months in people with moderate-to-severe generalised anxiety disorder, with a significant proportion of participants still in remission at 12 weeks.

For the first time, data from real-world application of psilocybin treatment under a regulated program was published by one of the Oregon clinics providing treatment, sharing insights into how the legal, real-world version of the treatment works, who can access it, and whether the benefits observed in trials translate to broader populations.

Longitudinal data strengthened claims of sustained benefit in selected cohorts. Multiple follow-up reports published in 2025 described durable antidepressant effects at extended intervals after single or limited psilocybin administrations, although most samples remained small and non-randomised. These findings have prompted calls for larger, controlled long-term studies. 

The FDA’s public release of the complete response letter on Lykos Therapeutics’ trials on MDMA therapy highlighted durability and safety questions, prompting re-examination of trial design and participant selection in MDMA and related programmes.

Cambridge Psychedelic Research Group formally launched in 2025, creating a new hub for clinical trials and interdisciplinary research in the UK, including pathways for patient recruitment and academic-industry collaboration.

Compass Pathways is one of the companies spearheading clinical development of synthetic psilocybin, the compound naturally found in psilocybin mushrooms. 

Founded in 2016, Compass Pathways built its company around COMP360, a proprietary synthetic psilocybin formulation. Currently ready to begin a second phase 3 trial in treatment-resistant depression, Compass is expecting to potentially lead the first approval of a classic psychedelic by the U.S. FDA.

Psychedelic Health sat down with Compass Pathways CEO Kabir Nath, to discuss the company’s most recent milestones and plans for the future, ahead of the company’s stage appearance at PSYCH Symposium: London 2025, happening at Conway Hall, December 4.

In its most recent quarterly call, Compass emphasized the successful primary endpoint in its first Phase 3 trial, positioning COMP360, as the first psychedelic treatment to reach this milestone in treatment-resistant depression. 

The company reported plans to accelerate commercial readiness, expand provider education, and continue learning from their clinical delivery collaborations to support regulatory submission and launch timelines, underscoring its transition from experimental research toward potential market entry.The company recently announced that based on recent successes and developments, it’s pulling forward the projected launch date for COMP360 by about one year.

“We had a good discussion with the FDA about the potential for a rolling submission and rolling review, which for the psychiatry division would definitely be something they have not historically done,” said Nath.

These measures could put the drug in a fast track status with the FDA, allowing it to reach the market sooner than previously expected.

Nath says that because Compass has already completed enrollment in their second psilocybin study, they’re now looking to have a significant data release in the first quarter of next year.

“That suggests we could potentially be looking at a launch in early 2027,” he said, which would mean a pull forward of roughly one year from previous projections of a launch in 2028.

“We have runway into 2027, so we have cash to see us through all of our phase 3 readouts,” he said.

In its most recent financial results, the company reported having $185.9 million USD (£140.7 million) in cash or cash equivalents.

Dealing With Lykos Therapeutics’ FDA Rejection

Last year, the U.S. FDA rejected an application from Lykos Therapeutics, formerly MAPS, for the approval of MDMA therapy. The event marked a low point in the history of the recent psychedelic renaissance, taking many activists and investors to wonder when one of these compounds would finally reach approval by a major regulating body.

Nath made a point to separate Compass’ pipeline from that of Lykos.

“MDMA is not a classic psychedelic, MDMA is more of a pathogen, and so the therapy component is really important for MDMA, the actual dialog, the interaction with a therapist. For classical psychedelics like psilocybin or LSD, that’s not the case” he said.

While Lykos were trying to get a drug/therapy combination approved, Compass is trying to get a drug with monitoring and support approved. This marks a major difference from how the two companies present their results to the FDA.

Since Lykos was a spin-off from MAPS, which is an NGO working for decades to gather data on MDMA treatment, this could have led to issues around “some of the basics around safety, safety reporting, and collection of adverse events,” said Nath.

While Compass is looking at the U.S. market first, it has designed its studies with scientific advisors from Europe and the UK.

“We know that if these studies are successful, they would meet regulatory standards in Europe, but obviously that would be a separate application,” Nath said.

How Does Compass See Its Role and Influence As a Market Leader?

If COMP360 becomes approved, it will invariably influence the broader psychedelics space since it would be the most significant event since psychedelics came back into mainstream attention for healthcare use, starting in the early 2000s.

How does Compass see its ability to influence the broader market and levels of excitement moving investors and the general audience to become interested in these drugs?

“We are focused on executing this ourselves and, getting COMP360 across the finish line. But I completely recognize that, because we are likely to be the first, by some way, what we do and how we set about commercializing and being successful, is going to influence how others do,” says Nath.

Still, Nath is sure to point out that “the infrastructure that’s already been established for Spravato is actually the infrastructure that most of us in psychedelics will be plugging into.”

That means that treatment with COMP360 could potentially be provided by the same clinics currently providing treatment with ketamine, which means the drug could count with an existing infrastructure of thousands of clinics across the U.S., the UK and Europe ready to provide its treatment.

Ambio Life Sciences, a company known for its physician-led ibogaine therapy programmes, has been thrust into the global spotlight with the release of In Waves and War on Netflix, a documentary filmed at one of its treatment facilities, while simultaneously announcing the opening of its first European clinic in Malta. 

Ambio is a clinical organisation that offers medically supervised ibogaine programmes focused on trauma recovery, neuroregeneration and substance use disorders. The company’s leadership will be part of PSYCH Symposium: London 2025, occurring at London’s Conway Hall on December 4.

 In Waves and War 

The new Netflix documentary follows several former U.S. Navy SEALs as they confront the psychological and neurological scars of combat, including post-traumatic stress and traumatic brain injury, through ibogaine-assisted therapy. Filmed partly at Ambio’s clinic in Mexico, the film presents a rare, direct view of what such treatment entails and how it fits into the broader debate about the role of psychedelics in addressing mental health and substance use disorders.

In the film, Ambio showcases a clinical model that departs from the underground or informal settings that have long characterised ibogaine use. The company’s approach, grounded in medical oversight and structured aftercare, contrasts sharply with earlier practices and aligns with emerging calls for regulated, evidence-informed psychedelic care.

Ambio Life Sciences CEO and Co-Founder Jonathan Dickinson said to Psychedelic Health that the film’s timing is both urgent and consequential. “It is now 24 years after the start of the Global War on Terrorism, and rates of veteran suicide continue to rise. This film is being released to a global audience at a crucial time. The good news is, ibogaine is uniquely capable of addressing the intersection of mental health challenges, neurocognitive injury, and substance use,” he said. “Over the past five years, ibogaine in Mexico has quietly become the treatment of choice for the operator community, many describing immediate and lasting relief, often after years of failed conventional treatments.”

The documentary also foregrounds patient voices. Retired Navy SEAL and Ambio patient DJ Shipley, one of the film’s central figures, described his experience: “Ibogaine allowed me to become a better, more well-rounded version of myself, someone with more empathy, more compassion, but without losing my edge. I’m incredibly proud of my castmates and the directors. They did a beautiful job telling our story. I truly hope this film changes lives and helps people find strength in its vulnerability.”

The New Malta Clinic

Alongside the film’s debut, Ambio announced the launch of its new clinic in Malta, described as Europe’s first physician-led ibogaine facility. According to the company’s release, the centre offers a structured residential programme that combines medical screening, 24-hour physician supervision and integrated therapeutic support. Treatments will take place in a medically equipped environment with on-site emergency protocols, a full-time medical team, and facilities designed for private accommodation and holistic therapies such as breathwork and somatic work.

The Malta site marks Ambio’s first expansion beyond North America and establishes a strategic base for patients from Europe, Canada and the eastern United States. By creating a clinic that operates under formal medical oversight, Ambio seeks to raise safety standards and expand accessibility in a field that has often been criticised for its lack of regulation.

Ambio Life Sciences, founded by clinicians with experience treating addiction and trauma through ibogaine, positions itself as a provider of evidence-based, medically supervised psychedelic care. The company’s work has focused on neuroregenerative and trauma-related conditions, with a particular emphasis on veterans and first responders.

The combination of global media exposure and clinical expansion underscores Ambio’s role in shaping the public perception and practical delivery of ibogaine treatment. As both scrutiny and interest in psychedelic medicine intensify, Ambio’s visibility through In Waves and War and its new European operations will test how far the treatment can move toward mainstream medical acceptance.
