Filter by:This is a multicenter, randomized, double-blind, placebo-controlled study designed to evaluate the efficacy and safety of intramuscular (IM) injections of Risperidone ISM® (75 or 100 mg) or placebo, in patients with acute exacerbation of schizophrenia.
The purpose of this study is to evaluate the efficacy of brexpiprazole compared with placebo as maintenance treatment in adults with schizophrenia.
The objective of this study is to evaluate the efficacy and safety of RP5063 relative to placebo for the treatment of schizophrenia or schizoaffective disorder.
The purpose of this study is to compare the effectiveness, safety and tolerability of three different doses of OPC-34712 with placebo in the treatment of acute schizophrenia in adults.
The purpose of this study is to assess the efficacy, safety, and tolerability of fixed doses of OPC-34712 versus placebo for the treatment of adult subjects with an acute relapse of schizophrenia.
This is a randomized (patients are assigned different treatments based on chance), double-blind (neither the patient nor the physician knows whether drug or placebo is being taken, or at what dosage), active-controlled, flexible-dose, parallel group, multicenter study. The study consists of a screening phase, a double-blind treatment phase (6 weeks) and a safety follow-up phase (1 week). The patients in this study will be randomized to 1 of 2 treatment groups to receive extended release OROS paliperidone or Olanzapine once daily for the 6-week double-blind treatment phase. Randomization will occur in a ratio of 1 (extended release OROS paliperidone) to 1 (Olanzapine). Patients must be hospitalized at least 14 days after entry. Those who receive extended release OROS paliperidone will start at a dosage of 6 mg taken daily, dose may be titrated up by 3mg/day every 7 days, or down rapidly based on the balance of efficacy (effectiveness of drug) and safety/tolerability assessed by the investigator. After the initial 7 days, dose could be flexible within 3-12mg/day. Those who receive olanzapine will start at a dosage of 5mg taken daily, dose may be titrated up by 5mg/day every 7 days, or down rapidly based on the balance of efficacy and safety/tolerability assessed by the investigator. After the initial 7 days, dose could be flexible within 5-15mg/day. Efficacy parameters include Positive and Negative Symptom Scale (PANSS) score, Clinical Global Impression-Severity (CGI-S) and Personal and Social Performance (PSP) score per assessment visit. The primary efficacy is the change in PANSS from baseline to the last post-randomization assessment. Safety assessments include the adverse events, changes in physical examination, vital signs, laboratory tests at pretreatment and posttreatment.
Controlled studies using the orthomolecular approach have been few (Deutsch, Ananth, & Ban, 1977). Those that were done were performed in chronic schizophrenia or in populations that included bipolar and schizoaffective patients. Both of these diagnostic groups are not today considered to benefit from the orthomolecular approach. Moreover, some negative studies of high-dose niacin were done in patients who were not otherwise given general counseling for good diet as described above. Therefore, this proposal is to study in a controlled manner carefully defined first onset schizophrenic patients using the protocol advocated by Osmond and Hoffer (1962). Patients can enter the study if they have been ill less than 1 year and are in their first hospitalization.
