Drugmaker Lykos Therapeutics introduced on Aug. 9, 2024, that the Meals and Drug Administration declined to approve the corporate’s software for using MDMA-assisted remedy within the remedy of post-traumatic stress dysfunction. It’s the first such determination issued on a psychedelic drug software.
Many traders and researchers have been predicting a psychedelics growth, with MDMA being simply the primary of various psychedelics within the drug improvement pipeline.
The FDA’s determination has disenchanted psychedelic remedy advocates, and the inventory costs of psychedelic business leaders tumbled with the announcement. However the FDA did make suggestions as to how the applying might be improved in such a means that MDMA would possibly obtain future approval.
Yet one more setback got here days later when the journal Psychopharmacology retracted three papers associated to MDMA-assisted remedy, citing “protocol violations amounting to unethical conduct,” notably in a single scientific trial.
The Dialog requested drug researcher Benjamin Y. Fong from Arizona State College about what the FDA’s determination entails and what it means for the way forward for psychedelic drugs.
What’s MDMA, and what forms of situations might it deal with?
MDMA, or midomafetamine, is thought colloquially as “molly” or “ecstasy.” It’s technically an amphetamine – just like the drug within the attention-deficit/hyperactivity dysfunction treatment Adderall – however MDMA is commonly categorized as a psychedelic.
It’s thought-about to be extra pleasure-inducing than different amphetamines, and because of this it has been a preferred occasion drug. Some researchers name MDMA an “empathogen,” or a “feeling enhancer.”
Whereas MDMA is presently a Schedule I drug – which means that the Drug Enforcement Administration considers it to be extremely harmful with no accepted medical use – various scientific trials level to the advantages of utilizing MDMA together with discuss remedy for sufferers affected by PTSD.
The FDA granted “breakthrough therapy” standing to MDMA-assisted remedy in 2017, which sped alongside its improvement and assessment.
PTSD impacts between 9 million to 13 million individuals yearly within the U.S., and no novel therapies for the situation have been developed up to now 20 years.
Lykos Therapeutics filed an software for FDA approval of its model of MDMA-assisted remedy for PTSD in February 2024. In it, the drug is paired with a sort of psychotherapy meant to carry out a affected person’s “inner healing intelligence”, which Lykos defines as “a person’s innate capacity to heal the wounds of trauma.”

Why did the FDA decline approval of Lykos’ MDMA-assisted remedy?
In June 2024, an FDA advisory committee voted overwhelmingly towards the concept that the related scientific trials had proved the efficacy of MDMA for the remedy of PTSD.
Simply as decisively, the panel additionally voted towards the concept that the advantages had been proven to outweigh the dangers, reminiscent of elevated blood stress and abuse potential.
At the moment, the advisory committee took subject with a number of features of Lykos’ software. First, it famous the issue of “functional unblinding,” which is the truth that most individuals collaborating within the trial would know if they’re on a strong psychoactive substance or not, biasing the outcomes.
It is a downside for any psychoactive treatment, and Lykos critics imagine the corporate ought to have adopted FDA steering that it use an “active placebo” – a placebo that additionally has psychoactive results – for comparability in its earlier scientific trials.
The panel additionally raised questions concerning the type of psychotherapy used alongside MDMA, in addition to moral considerations about varied types of misconduct in Lykos’ trials. In one of many firm’s research, a participant reported sexual misconduct by the therapists concerned.
The FDA will not be certain by the votes of such advisory our bodies, nevertheless it sometimes follows their steering. So the choice on Friday was no nice shock.
What does the FDA’s determination imply for the way forward for MDMA?
The FDA requested a further section 3 research, the stage of scientific trials that rigorously demonstrates the protection and efficacy of a specific remedy compared to customary remedy.
Lykos said that it’s going to request a reconsideration of the choice and talk about the FDA’s suggestions with the company to make sure that the corporate is on the fitting path ahead.
Lykos CEO Amy Emerson, who known as the choice “deeply disappointing,” says she believes it’ll take “several years” to conduct the brand new trial.
However with the journal Psychopharmacology’s retraction of three papers associated to this work, Lykos has a troublesome street forward of it.
How would possibly this determination have an effect on different psychedelic medication’ approval?
One distinguished psychedelics firm, Compass Pathways, is mostly thought-about subsequent in line for FDA approval of a psychedelic drug, with section 3 scientific trials for its artificial psilocybin effectively underway. There are different corporations making ready for section 3 trials of their very own proprietary compounds.
Within the wake of the advisory panel judgment in June, Compass famous that it isn’t pairing its drug with remedy in the way in which Lykos has. One other firm claimed that it has a “better trial design that is more in line with FDA guidance.”
Different psychedelics corporations clearly imagine they will nonetheless succeed the place Lykos has not.
Do psychedelics face distinctive challenges?
The FDA’s determination was extra about Lykos’ particular strategy than an outright rejection of psychedelics for therapeutic use.
However psychedelic drug improvement is a fraught course of by nature. The medication concerned induce a severely altered state that places individuals in a susceptible place. Some individuals within the business that I’ve spoken to imagine it is almost unimaginable to keep away from accusations of impropriety, given the character of the expertise.
Most analysis additionally pairs psychedelic medication with some type of remedy or facilitation, and because the FDA has made clear, its position is to evaluate medication, not the psychotherapies that may go together with them.
The interplay between the medication and the human aspect concerned within the remedy is the topic of some debate. Lykos’ missteps in its software shine a lightweight on among the ways in which corporations concerned in psychedelic drug improvement face distinctive obstacles on the way in which to FDA approval.
