Translational Investigation of the Glutamatergic and GABAergic System in Schizophrenia
SchizophreniaIn the last years, the imbalance between excitatory and inhibitory neuronal activity has come to the fore as a possible molecular disease mechanism of schizophrenia . Pharmacological studies have suggested different fMRI and EEG markers of that molecular dysfunction (resting state connectivity changes, auditory mismatch and steady state deficits). However, previous research is inconclusive regarding their genetic basis, their reliability, inter-individual relationship as well as disease specificity. Therefore, in this study we aim at estimating the effect sizes, test-retest-reliability and clinical correlates of the respective markers in a comparative fashion in patients with schizophrenia, their relatives and healthy control subject. To assess their molecular validity, we will assess their relationship with glutamatergic and GABAergic genotypes and cellular disease models. The proof of such a relation would give the opportunity of detecting a glutamatergic and GABAergic imbalance throughout non-invasive imaging. Furthermore, it would help deepening our understanding of the molecular pathophysiology of mental disorders which will be essential for the development of more effective drugs.
Examining a Digital Health Approach for Advancing Schizophrenia Illness Self-management and Provider...
SchizophreniaSchizo Affective Disorder1 moreThe effective treatment of schizophrenia is very challenging due to a number of factors. These include issues such as poor engagement with treatment plans and care providers, limited contacts with providers due to under-resourced health services, and the challenges inherent to schizophrenia symptoms. The outcomes of these problems include frequent, lengthy, and costly hospital readmissions, low quality of life, high levels of distress, and difficulties engaging in valued community roles. Digital Health technologies are a promising model to help address these problems. They are a low cost and accessible form of support and have not been substantively developed or studied for people with schizophrenia spectrum illnesses. In this study, the feasibility of one such technology that is in development will be tested: App4Independence (A4i). A4i provides customized coping prompts, peer-peer networking, and a portal that facilitates better provider engagement. This research will provide critical information in the development of this new technology to address a key problem in the field - how to enhance care in a resource-limited context where provider-patient contacts are brief, infrequent, and rely on in the moment recall and self-advocacy by patients. These findings will lay the groundwork for a larger program of research and software development that will (i) validate the technology across multiple sites and, (ii) catalyze engagement with healthcare systems and caregiver networks to scale-out access to this promising resource.
Pharmacokinetics, Safety, and Tolerability of Lumateperone Long-Acting Injectable in Patients With...
SchizophreniaThis is an open-label study to determine the pharmacokinetics, safety and tolerability of single ascending doses of lumateperone long-acting injectable formulation in patients with schizophrenia. Patients will be enrolled in one of up to four cohorts. All patients will receive oral lumateperone for 5 days, followed by a 5-day washout of oral lumateperone, then followed by a single dose of lumateperone LAI.

SchizophreniaA 2-part, crossover design, open-label treatment trial with 4 periods, 4 sequences (Part A) to evaluate MR formulations of CVL-231 and a 2 periods, 2 sequences (Part B) to understand effect of food on CVL-231 exposures from an MR formulation.
Theta tACS During Working Memory Training: A Pilot Study of the Effects on Negative Symptoms of...
SchizophreniaSchizoaffective Disorder5 moreIn this randomized double-blind trial, we investigated whether externally induced left-hemispheric frontoparietal theta synchronization by multi-electrode online theta (6Hz) transcranial alternating current stimulation (tACS) would enhance the influence of a working memory training on negative symptoms of schizophrenia.
A Multiple Dose Study to Assess the Safety, Tolerability and PK of Risperidone Extended Release...
Schizophrenia SchizoaffectiveLyndra is developing an oral, extended release (ER) formulation of risperidone (LYN-005) presented in a capsule dosage form with the intent of reducing the frequency of dosing orally-administered medications to once weekly or less and thereby improving the management of schizophrenia. Study LYN-005-C-004 will evaluate the safety, tolerability, and pharmacokinetics (PK) of multiple dose administration of the ER formulation at two dose levels of LYN-005 relative to IR risperidone.
RELATE - Efficacy and Feasibility of a Cognitive Behavioural Module for Distressing Auditory Verbal...
Verbal Auditory HallucinationPsychotic Disorders2 moreAuditory hallucinations (AH) are associated with distress and reduced functioning. Psychological interventions show some promising effects on psychopathology but have been less successful in reducing AH related distress, which patients report to be a priority. Research suggests that distress is associated with the hearer relating to AH in a passive and subordinate manner. A novel approach thus teaches assertive responses to AH through the use of experiential role-plays. A single centre pilot study in the United Kingdom evidenced a large effect of this approach on AH distress but independent multicentre studies are required to ascertain effectiveness across different settings. The planned feasibility trial aims to estimate the expected effect for a subsequent fully powered prospective, randomized, controlled, parallel-group, two-armed, multicentre, open trial set up to demonstrate that adding a Relating Module (RM) to Treatment as Usual (TAU) is superior to TAU alone. Feasibility questions relate to patient recruitment, therapist training and therapy monitoring in different types of psychological and psychiatric outpatient facilities.
