The primary aim is to investigate whether six weeks augmentation with clonidine of the antipsychotic treatment will reduce positive and negative symptomatology of treatment resistant schizophrenia patients. Important secondary goals of this project…
In Part 1, a single dose will be administered of RO6889450 or placebo (same formulation but then without the active ingredient RO6889450). The purpose of Part 1 is to investigate how safe RO6889450 is and how well RO6889450 is tolerated. Part 1 will…
Primary:to evaluate the safety and tolerability of EVP-6308 after single and multiple ascending dose administration in healthy subjects.Secondary:to determine the pharmacokinetics of EVP-6308 and select metabolites following single and multiple oral…
The study will be performed in 2 parts, Parts 1 and 2. The volunteers can only participate in one of the two parts of this study. The purpose of Part 1 of the study is to investigate to what extent RO6806127 is tolerated. It will also be…

To examine the effect of L-dopa addition to optimal D2-blocking antipsychotic treatment on positive symptoms, negative symptoms, cognitive symptoms and extrapyramidal symptoms in schizophrenia.
This proposal entails a proof-of-concept study into the neuropsychological effects of memantine augmentation in a random cross-over comparison to placebo, as add-on treatment to ongoing clozapine in severely mentally ill (SMI) patients with…
- to examine the safety and tolerability of the research medication- to examine how the research medication is absorbed, broken down and excreted by the body.
The main objective is to find a pre- and post-valaciclovir treatment difference in hippocampal inflammation, as measured with positron emission tomography, in schizophrenic patients exposed to a psychotic episode. The secondary objective is to…
to assess the safety and tolerability of single ascending doses of RO5545965 in healthy subjectsto investigate the pharmacokinetics (PK) of RO5545965 (and its metabolite(s) if appropriate)to investigate the pharmacodynamic (PD) effects of…
The primary objectives of the study are to:• Evaluate efficacy of 24 weeks treatment with RO4917838 in the PANSS negative symptom factor score in patients with persistent, predominant negative symptoms of schizophrenia treated with antipsychotics.•…
Transcranial magnetic stimulation (TMS) is a non-invasive, save method to stimulate the cerebral cortex and thereby alter neuronal function. In TMS a coil, which delivers brief magnetic pulses is placed adjacent to the scalp. The magnetic field…
We propose to investigate the effect of administering a broad-acting, potent immune suppressive agent early in the course of the disease as this may prevent neuronal damage caused by low-grade inflammatory processes in the brain. It is expected that…
to assess whether a single-dose of levodopa improves cognitive symptoms and balances goal-directed and habitual behavior.
The objectives are to assess the pharmacokinetic and pharmacodynamic effects of sub-anesthetic ketamine administration, to assess the optimal dose of ketamine and gender differences, to compare different oucome measures for psychomimetic symptoms…
The following research questions are formulated:A. Does exposure to cannabis (THC) result in an increased dopamine response in the striatum (as measured with PET)? And does cannabis use lead to an increase in psychotic experiences or symptoms?B. Do…
The purpose of the study is to investigate how well LY2165766 is tolerated, and to investigate whether LY2165766 administration is associated with body weight gain in comparison to placebo. Olanzapine is included in this study as a positive control…
