Clinical Trial Summary

A study to evaluate the safety, tolerability, efficacy, pharmacokinetics, and electrophysiology of ANAVEX3-71 in patients with Schizophrenia.


Description:

ANAVEX3-71-SZ-001 is a two-part study. The first part is Part A: Multiple Ascending Dose, PK, safety, and dose selection. The second part is Part B: Double Blind, Placebo Controlled for exploratory efficacy and continued repeat-dose safety. This study will investigate the effects of ANAVEX3-71 in patients with Schizophrenia for the first time. This is an in-patient study. In both parts, participants will undergo either 10 or 28 days of dosing (Part A and Part B, respectively). Standard clinical outcome measures used in the clinic and novel fluid and electrophysiological biomarkers will also be assessed.

Primary EEG-ERP - Passive, Duration Deviant, Oddball ERP Electroencephalography (EEG) and event-related potential (ERP) measures of the duration deviant mismatch negativity paradigm. In this paradigm, 2 tones of the same frequency and sound intensity, one short duration (Standard) and one longer duration (Deviant), are sequentially presented to the patient through inserted earphones. Standard stimuli are presented more often than Deviant stimuli. While the auditory stimuli are being played, the patient is instructed to perform a picture-word matching task where they press a button on the COGNISON® handset when they see a picture and a word on a monitor positioned in front of them that do not match. [Part A and Part B] Up to 12 days (Part A) and Up to 30 days (Part B)
Primary EEG-ERP - Active, Auditory, Oddball ERP Electroencephalography (EEG) and event-related potential (ERP) measures. In this paradigm, 2 tones of the same sound intensity, one low frequency (Standard) and one higher frequency (Target) are sequentially presented to the patient through inserted earphones. The Standard stimuli are presented more often than the Target stimuli. The patient is told to listen for the high-frequency stimuli (Target) and press a button on the COGNISION® handset as fast as they can. [Part A and Part B] Up to 12 days (Part A) and Up to 30 days (Part B)
Primary EEG-ERP - Auditory Steady State Response Electroencephalography (EEG) and event-related potential (ERP) measures. In this paradigm, a short stream of clicks is repeatedly presented to the patient through inserted earphones. While the click-streams are being presented, the patient is instructed to fix their gaze on a white cross displayed on a computer monitor positioned in front of them. [Part A and Part B] Up to 12 days (Part A) and Up to 30 days (Part B)
Primary EEG-ERP - Resting EEG Electroencephalography (EEG) and event-related potential (ERP) measures. In this paradigm, the patient is asked to close their eyes and relax for 5 minutes while EEGs are recorded. [Part A and Part B] Up to 12 days (Part A) and Up to 30 days (Part B)
Secondary Positive and Negative Syndrome Scale (PANSS) The Positive and Negative Syndrome Scale (PANSS) is an approximate 30-minute structured interview scale used for measuring the symptom severity of patients with schizophrenia. It is widely used in the study of antipsychotic therapy. [Part A and Part B] Up to 12 days (Part A) and Up to 30 days (Part B)
Secondary Brief Assessment of Cognition in Schizophrenia (BACS) The Brief Assessment of Cognition in Schizophrenia (BACS) assesses the aspects of cognition found to be most impaired and most strongly correlated with outcomes in patients with schizophrenia. The BACS requires less than 35 min to complete. [Part A and Part B] Up to 12 days (Part A) and Up to 30 days (Part B)
Secondary Clinical Global Impressions Scale Schizophrenia (CGI-SCH) The Clinical Global Impression-Schizophrenia Scale (CGI-SCH) assesses the positive, negative, depressive, cognitive symptoms, and overall severity of schizophrenia. The (CGI-SCH) scale is a brief assessment instrument which is originally adapted from the Clinical Global Impression (CGI) scale and the CGI Bipolar Patients (CGI-BP) scale. It was developed to study the outcome of antipsychotic treatment in schizophrenia in an observational study (Schizophrenia Outpatient Health Outcomes (SOHO) Study. The CGI-SCH has shown strong validity, and it has slightly higher interrater reliability than the PANSS (Kumari et al., 2017). [Part A and Part B] Up to 12 days (Part A) and Up to 30 days (Part B)
Secondary Virtual Reality Functional Capacity Assessment Tool (VRFCAT) The Virtual Reality Functional Capacity Assessment Tool (VRFCAT) is a computerized measure that was developed to be a reliable, valid, and sensitive measure of functional capacity, with the potential to demonstrate real-world functional improvements associated with cognitive change. The VRFCAT, typically administered within 15 minutes, presents patients with a realistic simulated environment to re-create routine activities of daily living, including, e.g., exploring a kitchen, catching a bus to a grocery store, finding/purchasing food in a grocery store, and returning home on a bus. To permit repeated testing while avoiding learning effects, 6 alternate forms were created that vary the ingredients stored in the cabinets, items on the recipe and grocery list, cost of the bus rides, cost of groceries, and money available in a wallet. [Part A and Part B] Up to 12 days (Part A) and Up to 30 days (Part B)
Secondary Blood measurements of chitinase-3-like protein 1 (YKL-40) Previous studies have identified genetic variants of the chitinase-3-like protein 1 gene (which expresses YKL-40) and elevated serum YKL-40 with an increased risk for schizophrenia in certain populations (Ohi et al., 2010). Subsequent studies in broader populations demonstrated monocyte activation and elevated YKL-40 in the plasma and cerebrospinal fluid of patients experiencing first-episode psychosis (Orhan et al., 2018). This study seeks to explore blood levels of YKL-40 before and after treatment with ANAVEX3-71 to investigate the immune calming effects associated with Sigma-1 receptor activation in patients with schizophrenia. The expected effect of Sigma-1 activation on inflammation may be an upstream effect by attenuating disease-related, chronic pro-inflammatory signaling by monocytes and glia, to prevent downstream injury due to inflammation (Zhang et al., 2023). [Part B] Baseline to End of Treatment (Day -2 to Day 28)
Secondary Blood measurements of glial fibrillary acidic protein (GFAP) Immune dysfunction theories of schizophrenia include glial-related dysfunction and assume that initial disturbances in glial cells can lead or contribute to neuronal abnormalities that drive symptoms of schizophrenia. Glial perturbations in schizophrenia are associated with a neuroinflammatory response and elevated levels of glial fibrillary acidic protein (GFAP) (Wang et al., 2015). [Part B] Baseline to End of Treatment (Day -2 to Day 28)
Secondary Blood measurements of circulating amino acid metabolites Changes in the metabolomic profile of circulating amino acids and related metabolites are implicated in the etiology of numerous neurological and neuropsychiatric disorders (Donatti et al., 2020). Metabolomics studies of patients with schizophrenia demonstrate numerous metabolite signatures of schizophrenia including elevated glutamate (Davison et al., 2018). Changes in these metabolite levels may result from treatment, based on previous research into the treatment of other central nervous system disorders with Sigma-1 receptor agonists such as ANAVEX3-71. [Part B] Baseline to End of Treatment (Day -2 to Day 28)
Secondary Exploratory DNA/RNA, including whole genome analysis and whole transcriptome mRNA Exploratory DNA/RNA, including whole genome analysis and whole transcriptome mRNA. Assessed in whole blood via next generation sequencing (NGS) method. Whole genome sequencing (WGS) with 30x read depth. These measurements will be used to understand the potential effects of genetic variation on treatment response and the potential effect of treatment on changes in gene expression which may be relevant to the etiology of schizophrenia. [Part B] Baseline to End of Treatment (Day -2 to Day 28)
