NCT00425815
The TURNS is a National Institute of Mental Health (NIMH) funded contract for the evaluation of new compounds for the treatment of cognitive impairments in schizophrenia (HHSN 27820044 1003C; P.I.: Steve Marder, M.D.). Despite advances in the safety, tolerability, and effectiveness of antipsychotic medications for the treatment of schizophrenia, many patients continue to be plagued by impairments in social and work functioning. Persons with schizophrenia commonly show deficits in a number of areas of cognition that include impairments in attention, memory, and executive functioning (the ability and organize one's behavior). Importantly, a large body of literature now shows a link between cognition and community functioning in schizophrenia. It is believed that treatments that improve cognitive deficits may lead to improvements in work and social functioning. A promising approach to improve the community functioning of patients with schizophrenia is to develop new agents that treat the cognitive deficits of the illness. One type of pharmacological compound that has shown promise at improving cognition is a group of drugs called ampakines. These drugs are believed to improve the activity of a neurotransmitter system in the brain called the glutamate system. Increased activity of this system has been linked to improvements in cognitive functioning. The current study is an eight-week trial comparing two doses of the ampakine drug, Org 24448, that will be added to patients' current atypical antipsychotic medication. One hundred thirty-five patients with schizophrenia, drawn from seven sites, will participate in the study. Cognition will be measured using a variety of paper-and-pencil and computerized measures from the consensus-derived NIMH Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) cognitive battery. Psychiatric symptoms and the ability to perform community-based tasks of daily living will also be measured. Because previous trials with this drug and other similar drugs have detected lasting cognitive benefits, this trial will also repeat clinical assessments four weeks after completion of the study medication.
NCT01885338
This study will evaluate the effect of the dietary supplement N-acetylcysteine (NAC) on electrophysiologic (EEG) markers related to cognition, as well as performance on psychological tests measuring cognition. The primary hypothesis is that participants treated with NAC will show improvements in cognitive function, as measured by EEG and performance-based tests.
NCT01266174
The purpose of this study is to determine if eltoprazine (as an adjunct to anti-psychotic medication) improves one or more aspects of cognitive impairment in adult schizophrenic patients.
NCT00731549
To evaluate the overall effectiveness of aripiprazole intramuscular (IM) depot as maintenance treatment in patients with schizophrenia.
NCT01488929
Negative symptoms and cognitive dysfunction in schizophrenia (CDS) are core features of schizophrenia. These negative symptoms and cognitive deficits have a devastating impact on the function, employment, and social interactions of patients with schizophrenia. Medications used to treat schizophrenia (e.g. atypical antipsychotics) do not improve negative symptoms or CDS. TC-5619 is being developed for use as an add-on therapy in combination with atypical antipsychotics to treat patients with negative symptoms and CDS.
NCT01157351
The study will assess the use of paliperidone palmitate compared with oral antipsychotic treatment in delaying time to a protocol-defined treatment failure over 15 months, in patients diagnosed with schizophrenia who have been incarcerated.
NCT01149655
This will be a randomized, double-blind, placebo-controlled study consisting of a screening period, a conversion phase (Phase 1), a stabilization phase (Phase 2), and a double-blind maintenance treatment phase (Phase 3), and a follow up period. Subjects may be either outpatients or inpatients between screening and through the time they reach stabilization at the end of Phase 2; hospitalization is not a study requirement. However, eligible subjects must be outpatients at the beginning of Phase 3. Subjects will be assessed weekly during Phase 1, weekly for the first 4 weeks of Phase 2 and 3, and biweekly for the remaining weeks during each of Phases 2 and 3. Subjects will be encouraged to call the investigators with any exacerbation of psychotic symptoms and/or any tolerability issues. The investigator will also have the option to phone the subjects and their guardian(s) at any time to ensure clinical stability. A data monitoring committee (DMC) will provide oversight for safety monitoring and reviewing the interim analysis. One interim analysis is planned after 75% of the total expected number of impending relapse events (28 events) are achieved and will be conducted by an independent data analysis center. The DMC will make a recommendation about stopping or continuing the study based on safety and efficacy reviews. The results of the interim analysis and individual subject data will remain blinded to the sponsor during the course of the study until the DMC determines that the study will conclude based on the results of the interim analysis, or the study is completed after 37 endpoint events.
NCT02202213
The purpose of this study is to evaluate the safety and tolerability of Lu AF11167 in patients with schizophrenia following various repeated dosing regimens of Lu AF11167 (alone or as added treatment to risperidone).
NCT00790192
Lurasidone HCl is a compound being developed for the treatment of schizophrenia. This clinical study is designed to test the hypothesis that lurasidone is effective, tolerable, and safe as compared with quetiapine XR short term among acutely psychotic patients with chronic schizophrenia.
NCT00905307
This will be a multicenter, randomized, double-blind, placebo-controlled study designed to assess the tolerability, safety, and efficacy of OPC-34712 (0.25 to 6.0 mg) for the treatment of adult subjects hospitalized with an acute relapse of schizophrenia. Aripiprazole (10 to 20 mg) is included as a positive control to confirm the assay sensitivity of the study. A total of approximately 563 subjects will be screened at an estimated 75 sites worldwide in order to obtain approximately 450 randomized subjects.
NCT01235520
This randomized, multi-center, double-blind, parallel-group, placebo-controlled study will evaluate the efficacy and safety of RO4917838 in patients with sub-optimally controlled symptoms of schizophrenia. Patients, on stable treatment with antipsychotics, will be randomized to receive daily oral doses of RO4917838 or matching placebo for 52 weeks, followed by an optional treatment extension for up to 3 years.
NCT00549718
Lurasidone HCl is a compound being developed for the treatment of schizophrenia. This clinical study is designed to test the hypothesis that lurasidone is more efficacious than placebo. The study will also evaluate the safety and tolerability of lurasidone as compared to placebo.
NCT01663532
The primary purpose of this study is to evaluate the overall efficacy of aripiprazole intramuscular (IM) depot as acute treatment in subjects with schizophrenia. The secondary purpose is to evaluate the safety and tolerability of aripiprazole IM depot administered every 4 weeks for 12 weeks to adult subjects with schizophrenia.
NCT00466323
The purpose of this study is to learn how to help veterans play a stronger role in shaping their mental health care. Specifically we want to see if we can help veterans improve their mental health treatment by helping them decide if they want to involve family in their mental health treatment, and if so, how. The study will compare a "family member provider" program to an "enhanced treatment as usual approach" in achieving these goals.
NCT00535145
The purpose of this study is to evaluate the tolerability and safety of paliperidone ER (extended-release) in doses between 3 milligrams per day and 12 milligrams per day in the treatment of patients with schizophrenia or schizoaffective disorder and liver disease.
NCT00524043
The purpose of this study is to assess the efficacy and safety of 1.5 mg/day dose of paliperidone Extended Release (ER) as compared with placebo when used to treat patients with schizophrenia.
NCT01909466
To determine the safety and tolerability of multiple-dose administrations of aripiprazole intramuscular (IM) depot in the deltoid muscle in adult subjects with schizophrenia
NCT01149551
The purpose of this study is to detect genetic associations for the development of schizophrenia (SZ) and bipolar illness (BP) by comparing Veterans with these diseases to "psychiatrically healthy" Veterans from Veterans Health Administration medical centers. In addition, the genetic basis for functional capacity and disability in Veterans affected with SZ and BP will be assessed, as will genetic predictors of suicidality and tardive dyskinesia. Finally, we will also establish a repository which allows for future genomic studies related to SZ, BP, and related disorders or sequelae.
