NEW YORK and BERLIN, Aug. 10, 2023 (GLOBE NEWSWIRE) -- atai Life Sciences (NASDAQ: ATAI) (“atai”), a clinical-stage biopharmaceutical company aiming to transform the treatment of mental health disorders, reported second quarter 2023 financial results and provided corporate updates.

“We continue to focus on our vision to heal mental health disorders so that everyone, everywhere can live a more fulfilled life,” said Florian Brand, CEO and Co-Founder of atai. “Looking ahead to the second half of 2023 and beyond, we believe we are well positioned to continue advancing our key clinical programs. We are especially encouraged by the progress our team has made in advancing RL-007 in the on-going randomized, placebo-controlled Phase 2b study as well as further evaluating VLS-01 in Part 3 of the on-going Phase 1 study. Today, we are pleased to report data from the Phase 1 trial of DMX-1002 (Ibogaine).”

“Current treatment options for Opioid Use Disorder (OUD) patients are not highly effective, with approximately 75% of patients undergoing therapy experiencing relapse within one year,” said Srinivas Rao, CSO and Co-Founder. “DMX-1002 has the potential to be a disease modifying treatment for this vulnerable patient population seeking to end their intractable cycle of drug dependence.”

“The results from this trial are consistent with the known side-effect profile of ibogaine, the active moiety in DMX-1002,” said Dr. Marek Malik, Professor Emeritus of Cardiac Electrophysiology, Imperial College, London and clinical advisor for the DMX-1002 development program. “Ibogaine is known to cause prolongation of the electrocardiographic QT interval. Drug-induced prolongation of the QT interval is a phenomenon that has been, with many but not all drugs, associated with cardiac arrhythmias. The QT-related side effect of ibogaine is anticipated to be manageable in a controlled setting with appropriate cardiac monitoring and safety protocols. In severe patient populations, like those living with OUD, ibogaine treatment administered in such a setting has a potential to be a paradigm shift for patients.”

DMX-1002 (Ibogaine) Phase 1 Results and Program Update:

Today, the company announced results from the Phase 1 study of DMX-1002, a cholinergic, glutamatergic and monoaminergic receptor modulator being developed for the treatment of OUD.

The single-blinded Phase 1 study assessed the safety, tolerability and pharmacokinetics of single-ascending doses of DMX-1002 in healthy volunteers. Oral doses of 3 mg/kg, 6 mg/kg & 9 mg/kg were evaluated in 20 participants. Results of the Phase 1 trial demonstrated that oral doses of DMX-1002 at 9 mg/kg achieved plasma concentrations in line with those described in previous studies^1,2 in which subjects reported psychedelic experiences and obtained therapeutic benefit in OUD.

The treatment-related adverse events (AEs) were similar to those observed in prior trials of DMX-1002, and nearly all (>94%) were rated mild-to-moderate in severity. There were no serious adverse events reported.

In one of the two participants who received 9 mg/kg of DMX-1002, QTc prolongation reached levels near those seen at the 10 mg/kg dose in the published literature³ (median change: 95ms). In this participant, a QTcF prolongation of 90-94ms was observed with a QTcF interval of 493-501ms. The patient was asymptomatic, with no cardiac arrythmias, and the QTc change resolved without intervention or sequalae.

During the study the company closely worked with cardiology experts who concluded that while QT prolongation of this order is a clinical risk, monitoring can help mitigate the risk to ensure the safety of patients, especially in a medical setting. The benefit of the drug will need to be defined in efficacy trials and will need to be weighed against the risks that have been defined.

The company plans to engage regulatory authorities to assess progressing DMX-1002 into an efficacy study in patients with OUD.

Recent Developments:

RL-007 (Pro-Cognitive Neuromodulator for Cognitive Impairment Associated with Schizophrenia)

• The on-going Phase 2b study is a randomized, placebo-controlled, double-blind, study of 6 weeks duration evaluating 20mg and 40mg of RL-007 vs placebo.
• The primary endpoint of the study is the change from baseline in the MATRICS Consensus Cognitive Battery (MCCB) neurocognitive composite score, a well-established regulatory endpoint.
• The company expects to report topline results from this study in the 2^nd half of 2024.
  

VLS-01 (N,N-dimethyltryptamine [DMT] for Treatment-Resistant Depression (“TRD”))

• The on-going Phase 1 study is designed to evaluate the safety, tolerability, PK and PD of VLS-01 delivered by intravenous (IV) infusion and using our proprietary oral transmucosal film (OTF) formulation.
• In Part 1 (IV) and Part 2 (OTF), VLS-01 was well-tolerated, with no dose-limiting toxicity and a favorable safety profile. VLS-01 produced generally dose-dependent increases in exposure, and administration resulted in subjective psychedelic experiences in the majority of subjects. Part 3 is exploring further optimization of PK and PD of our proprietary OTF formulation, including further dose ranging.
• The company expects to report additional clinical data in Q3 2023.
  

PCN-101 (R-Ketamine for TRD)

• The company recently announced completion of the Phase 1 open-label bridging study designed to assess the safety, tolerability, and pharmacokinetic profile of 60mg, 90mg and 120mg of PCN-101 delivered subcutaneously (SQ) as compared to 60mg of PCN-101 delivered IV.
• Pharmacokinetic (PK) analysis indicates that 120mg of PCN-101 delivered SQ resulted in an approximate doubling of drug exposure (AUC) while maintaining approximately the same maximum concentration (Cmax) as the 60mg IV dose.
• At the highest SQ dose of 120mg, rates of sedation (defined as MOAA/S score <5) and dissociation (defined as CADSS total score >4 and change from baseline >0) were each 14%. Overall, the data support testing the concept of at-home use of PCN-101 in future studies.
• The company continues to work with Perception Neuroscience to explore strategic partnership options.

EMP-01 (3,4-methylenedioxy-methamphetamine [MDMA] derivative for Post-Traumatic Stress Disorder (“PTSD”))

• The Phase 1 study is designed to evaluate the safety and tolerability of single-ascending doses of EMP-01 in healthy adult participants.
• Enrollment has been recently completed and the company expects to report initial clinical data in Q4 2023.

COMP360 (Psilocybin Therapy for TRD, Anorexia Nervosa and PTSD)

• COMPASS Pathways is currently conducting a Phase 3 program composed of two pivotal trials, each of which will have a long-term follow-up component. Topline data from Pivotal Trial 1 (COMP005) is expected in the summer 2024. The primary endpoint in both pivotal trials is the change from baseline in MADRS total score at week 6.
• The American Medical Association recently released the language of its new Current Procedural Terminology (CPT®) III code for Continuous In-Person Monitoring and Intervention During Psychedelic Medication Therapy. The code will go into effect and will be published in the CPT manual on January 1, 2024. Once effective, the new code will provide a mechanism to track and report the delivery of psychedelic treatments.
