About this study
Official title: A Study of Galantamine HBr as an Adjunctive Treatment to Atypical Antipsychotic Medications in Outpatients With Schizophrenia and Associated Cognitive Deficits.
The purpose of this study is to determine if adding extended-release galantamine hydrobromide, compared with adding placebo, to current atypical antipsychotic therapy is well tolerated and effective in improving cognitive impairment in patients with schizophrenia.
Read the detailed description
Galantamine acts on acetylcholinesterase, and has been shown to effectively treat cognitive symptoms in patients with Alzheimer's disease. Previous cellular research of nicotinic receptors has shown promising results, and it is theorized that the nicotinic system of patients with schizophrenia may be abnormal and may play an important role in the cognitive symptoms associated with schizophrenia. It is also postulated that galantamine may improve neuropsychiatric symptoms such as hallucinations, delusions, and apathy in patients with Alzheimer's disease. Atypical antipsychotic medications are effective treatment for schizophrenia patients but some symptoms remain. Therefore, galantamine may be a useful cotreatment for schizophrenia patients on atypical antipsychotic treatment. This is a pilot dose-ranging, 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), placebo-controlled multicenter study that examines the effects of taking extended-release galantamine hydrobromide (16 or 24 mg once daily) or placebo on the effectiveness in reducing symptoms of schizophrenia patients who are already taking an atypical antipsychotic medication. The safety of combined treatment is also examined. Measures of effectiveness include the Positive and Negative Syndrome Scale (PANSS) to measure neuropsychiatric symptoms of schizophrenia; the Clinical Global Impression (CGI) scale to measure change over the course of the study; the Brief Assessment of Cognition in Schizophrenia (BACS) for verbal memory and learning, working memory, motor function, attention, verbal fluency, and executive functioning; the Continuous Performance Test (CPT) for sustained attention and distractability; reaction time test (RTT) and finger tapping test (FTT) for psychomotor speed; Lexical and Semantic Fluency Test (LSFT) for language skills. As schizophrenia patients are a population with high nicotine use, and galantamine may act on nicotine receptors, blood levels of nicotine are also measured as varying nicotine levels could alter the effects of galantamine. The null hypothesis that there is no difference between the 2 groups (galantamine cotreatment and placebo) will be tested for each of the efficacy measurements (total PANSS, BACS, and CGI scores) at Week 8. Measures of safety include physical examinations, electrocardiograms (ECGs), clinical laboratory tests, measurement of plasma prolactin concentrations, pregnancy test for women, and incidence of adverse events. Adverse events that might be related to the medications are also monitored using the Simpson-Angus Extrapyramidal Side Effects Scale (SAS), the Barnes Akathisia Rating Scale (BARS), and the Abnormal Involuntary Movement Scale (AIMS). Extended-release galantamine hydrobromide or matching placebo capsules for once-daily dosing. Patients take 8 milligrams (mg) per day during Week 1, 16 mg per day during Week 2, and 16 mg or 24 mg per day (depending on randomization) during Weeks 3 to 8. Treatment groups are placebo capsule, 16 mg capsule, 24 mg capsule.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Extended-release galantamine hydrobromide in people with Schizophrenia, run by Johnson & Johnson Pharmaceutical Research & Development, L.L.C..
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 24 May 2011. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The key exploratory efficacy end points are the change from baseline to Week 8 in total PANSS score, total BACS score, and CGI global improvement and severity of illness scores.. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 May 2011; AzTrials last refreshed its copy on 8 Nov 2026.
