Positive results from Phase 2 Sleep Signal Analysis for Current Major Depressive Episode (SAMDE) Study
Highlights:
- Analysis of 400 patients in Phase 2 SAMDE study for current Major Depressive Episode (cMDE) study utilising MEB-001
- MEB-001 is TrivarX’s proprietary AI-driven algorithm which can assist with the effective screening of a cMDE
- MEB-001 performance results from Phase 2 SAMDE study reported high performance, marking a significant achievement in the Company:
- Sensitivity: 87% (95% CI 73-95%)
- Specificity: 72% (95% CI 66-77%)
- Positive Predictive Value: 35% (95% CI 27-45%)
- Negative Predictive Value: 97% (95% CI 93-99%)
- Results provide strong validation of MEB-001’s ability to assist in the screening and diagnosis of a cMDE – a condition which is commonly misdiagnosed
- There is currently no screening undertaken for cMDE in sleep centres in the US or globally, representing a major commercial opportunity for TrivarX
- Results advance TRI’s aim to become the first depression screening tool used in clinical practice in sleep centres
There is a well-established connection between mental health conditions, such as depression, and sleep disturbances. People with insomnia may have a tenfold higher risk of developing cMDE and among people with depression, 75% of sufferers have trouble falling or staying asleepi. Furthermore, misdiagnosis of major depressive disorder is estimated at upwards of 65% in the USii. Despite this, depression screening is not routinely included in sleep studies, even though up to 21% of people undergoing a sleep study have depressioniii.
Positive results from SAMDE study highlight MEB-001’s significant potential:
The objective of the study (ClinicalTrials.gov ID NCT05708222) was to use MEB-001 to detect the likelihood of a cMDE using Clinician Reporting Outcomes (CRO) assessment in individuals referred to a sleep clinic. A total of 400 patients were recruited across 15 sleep centres in the US. Out of these, 73 patients were excluded due to incomplete data or a split night/titration sleep study. MEB-001 also automatically identified 32 patients with significant anomalies in their sleep data. Notably, the MEB-001 algorithm was locked prior to the analysis ensuring no data from Phase 2 was used in its training.
Analysis of the results showed that MEB-001 reported promising performance across key parameters including sensitivity of 87% (95% CI 73-96%), specificity of 72% (95% CI 66-77%), positive predictive value (PPV) of 35% (95% CI 27-45%) and negative predictive value (NPV) of 97% (95% CI 93-99%) (refer table below).
These results provide considerable validation of MEB-001 and its ability in the screening and diagnosis of a current Major Depressive Episode (cMDE) in test subjects.
Management commentary:
Non-executive Chairman, David Trimboli said: “We are very excited to share the results from our Phase2 study, which highlight the effectiveness of MEB-001 in screening for cMDE. This is underscored by the significant increase in sensitivity coming from recent improvements to the underlying algorithm, which was increased from 71% in Phase 1, to 87% in Phase 2 – demonstrating that the algorithm can successfully identify more people with cMDE. Our very high NPV validates MEB-001’s potential as a screening test, with the likelihood of having depression when testing negative to be less than 3%.
“There is currently no screening undertaken for cMDE in sleep centres in the US or globally. Our most recent results reaffirm the potential of MEB-001 to become the first depression screening tool used in clinical practice in sleep centres and marks a significant achievement in the Company’s history.”

Positive Phase 2a Fibromyalgia Results Deliver Pain Reduction in 100% of Patients, Strengthening IP Position and Clinical Trial Strategy
- Phase 2a fibromyalgia trial undertaken with University of Michigan (“UOM’) with results presented at the IASP 2024 World Congress on Pain 9 August 2024 in the Netherlands
- All patients dosed with TRP-8802 (TYP’s oral psilocybin formulation), and administered psychotherapy reported an improvement in fibromyalgia pain severity, sleep, pain interference and at least 3 other endpoints measured one month after dosing
- Fibromyalgia is a condition associated with widespread pain – 1m people in Australiai and ~10m people in the USii suffer from it and there are currently limited treatment options
- Results highlighted that there was a clinically meaningful reduction in pain, pain interference and fatigue
- Patients also reported a number of other improvements including clinically meaningful improvements in quality-of-life measures such as sleep, physical activity, and the ability to participate in daily social activities
- Clinically meaningful reduction in anxiety and improved cognitive abilities were also reported in 4 out of 5 patients dosed
- In addition, one patient reported during follow-up that their sense of smell had returned following a COVID- 19 diagnosis in 2021
- Results highlight the significant potential for psychedelic-assisted therapy as a compelling treatment pathway for fibromyalgia when compared to the inadequacies of incumbent treatments
- Results considerably strengthen Tryp’s IP position and lay a strong foundation for a future trial using TRP- 8803 (IV-infused psilocin) – Phase 2 trial planning now underway and expected to commence H1 2025
- Additional clinical trials progressing well at MGH for patients with IBS, and the beginning of Cohort 3 in the TRP-8803 Healthy Volunteer Study expected to begin soon – updates to be provided in due course
The trial was designed to evaluate TRP-8802 (oral psilocybin) in conjunction with psychotherapy in patients with fibromyalgia, a condition associated with widespread pain and comorbidities that significantly impact daily living and patient well-being. The trial was undertaken by the UOM, a top-ranked public university in the US in collaboration with Tryp.
Results highlighted that 100% of patients experienced reductions in fibromyalgia pain, sleep disturbance and pain interference (refer figures one and two below).
Whilst appreciating the limitations of the small number of patients and the open label nature of the ‘signal’ style study, the results are highly encouraging and considerably strengthen TYP’s intellectual property position. Further, the results validate Tryp’s clinical trial approach targeting nociplastic pain with an initial focus on fibromyalgia and will inform an additional clinical study utilising TRP-8803 (IV-infused psilocin), which is expected to commence H1 2025.

Trial background:
The study was an open-label clinical trial with psychotherapy, seeking to evaluate TRP-8802 (oral psilocybin) in conjunction with psychotherapy in patients with fibromyalgia. A total of five patients were recruited and were administered two doses of TRP-8802 in 15mg initial dose and 25mg second dose formats, two weeks apart. Patients were administered psychotherapy in concert with TRP-8802 and results were compared to baseline values one month following the completion of the second dose.
