SAN JOSE, Calif., Aug. 1, 2024 /PRNewswire/ -- Lykos Therapeutics ("Lykos"), a company dedicated to transforming mental healthcare, announced new initiatives and measures for additional oversight for midomafetamine capsules in combination with psychological intervention ("midomafetamine-assisted therapy") for the treatment of post-traumatic stress disorder ("PTSD") in adults, if approved by the U.S. Food and Drug Administration ("FDA"). The new drug application ("NDA") included results from numerous studies, including two randomized, double-blind, placebo-controlled Phase 3 studies (MAPP1 and MAPP2) evaluating the efficacy and safety of midomafetamine-assisted therapy versus placebo with therapy in participants diagnosed with moderate or moderate and severe PTSD, respectively. Both MAPP1 and MAPP2 studies met their primary and secondary endpoints and were published in Nature Medicine.1,2
Lykos' NDA is the first to combine a drug and psychological intervention. While not regulated by the FDA, the practice of psychotherapy is already a regulated field with mandatory reporting requirements and oversight provided by licensing boards and professional societies. The healthcare professionals providing psychological intervention with midomafetamine, if approved, will utilize their clinical judgment to effectively deliver treatment, with appropriate oversight from these governing bodies. This will be in addition to controls and requirements set forth in the product labeling and the Risk Evaluation and Mitigation Strategy ("REMS") program.
"Given the novelty of this approach, we are taking steps to help ensure additional oversight for this drug plus therapy modality, if FDA approved, and to help integrate into the real-world healthcare setting," said Amy Emerson, Chief Executive Officer at Lykos Therapeutics. "It is critical for the millions of people suffering with PTSD, including veterans and survivors of physical and sexual assault, to have access to a potential new treatment option. To this end, we will work with external experts on an independent advisory board, focus our initial commercial rollout on centers of care where there are multiple layers of oversight and collaborate with others around therapy training. This process will establish a strong foundation to ultimately reach more patients in need of access to new treatment options."
The new initiatives and measures of additional oversight include:
"PTSD patients deserve the most effective treatments we can offer, and we want to make sure that we are well positioned to meet their needs," said Dr. Rothbaum. "Given the promise of midomafetamine-assisted therapy, we have been preparing our center to be an early leader in this potential science-driven combination treatment."
Midomafetamine capsules have not been approved by any regulatory agency. The safety and efficacy of midomafetamine have not been established for the treatment of PTSD. Investigational midomafetamine is also being studied in other indications. If approved, the FDA will require a REMS program, which is generally designed to prevent, monitor and/or manage a specific serious risk by informing, educating and/or reinforcing actions to reduce the frequency and/or severity of the event.
About PTSD
Prevalence and symptoms
PTSD is a serious mental health condition that can develop when a person experiences or witnesses a traumatic event.4 PTSD affects approximately 13 million Americans each year with women and disadvantaged or marginalized groups more likely to be affected.1,2 Military personnel also have a greater prevalence of PTSD than the general population.3 However, it may not be as widely known that the largest cause of PTSD is non-combat-related trauma (e.g., sexual violence, unexpected death of a loved one, life-threatening traumatic event or interpersonal violence).4 PTSD results in debilitating symptoms, including nightmares and intrusive thoughts related to the trauma, mental and/or physical distress in response to trauma-related stimuli, avoidant behaviors, negative thoughts and feelings, and hyperarousal.5 These symptoms can impact nearly all aspects of a person's life, including their interpersonal relationships.4 PTSD can also be a chronic condition, with a World Health Organization study showing that after ten years post-trauma, nearly a quarter of people had not recovered.6
Co-morbidities and economic impact
People with PTSD frequently experience anxiety, depression, substance use disorder and suicidal ideation.7,8 They may also have a greater incidence of medical conditions that impact their physical health, including heart disease, metabolic syndrome and asthma.9,10,11,12 U.S. Army Veterans who developed PTSD after military service have been shown to have an approximately two times greater risk of mortality than U.S. Army Veterans who did not develop PTSD after military service.15 In addition to the significant personal impact, PTSD has an enormous economic impact, resulting in an estimated annual cost of over $232 billion in the United States.13
PTSD treatment
Trauma-focused talk therapy, which concentrates on memories of the traumatic event or thoughts and feelings associated with the traumatic event, is first-line treatment for PTSD, which can be used alone or in combination with medication. 14 There are two SSRIs approved for the treatment of PTSD—sertraline and paroxetine.15 Studies have shown that talk therapy lessens the severity of PTSD symptoms, however, improvements in functioning and quality of life have been modest.16,17 Trauma-focused talk therapy is associated with a high risk of dropout and lingering symptoms, which occur in as many as two-thirds of people who complete treatment.18,19 Current treatments for PTSD are "reasonably efficacious"5, however, many people don't respond to treatment or stop treatment early, underscoring the urgent need for new evidence-based therapies and approaches to address this important public health issue.2 While there have been advancements in the management of PTSD, there have been no new drug treatments for PTSD approved by the FDA in over 20 years.20
About Midomafetamine-Assisted Therapy
Midomafetamine (MDMA) is commonly known to mental health professionals. In the 1970s and early 1980s MDMA was used in conjunction with talk therapy by mental health providers to help enhance patients' access, processing and communication of difficult emotions and experiences.21 MDMA is an entactogen— a class of psychoactive compounds that are differentiated from classic psychedelics (i.e., psilocybin, mescaline and LSD) and are defined based on their mechanism and demonstrated effects of increasing self-awareness, leading to introspection and personal reflection.22,23
In 1985, the DEA made MDMA a Schedule I drug under the Controlled Substances Act, preventing it from being used for recreational or medical use.24 Since then, research has suggested that MDMA may have potential as a catalyst to support psychotherapy by helping diminish the brain's fear response, allowing people to access and process painful memories without being overwhelmed.25
Lykos, with longstanding roots in advocacy for psychedelic medicine, was the first company to pioneer randomized, double-blind, placebo-controlled clinical trials evaluating the efficacy and safety of midomafetamine-assisted therapy as an investigational modality using midomafetamine in combination with psychological intervention. Lykos submitted an NDA to the FDA seeking approval of midomafetamine for the treatment of PTSD in adults. If approved by the FDA, the DEA would be required to reschedule midomafetamine to make it available for prescription medical use.
