Published Studies Related to Razadyne (Galantamine)

Long-term response to galantamine in relation to short-term efficacy data: pooled analysis in patients with mild to moderate Alzheimer's disease. [2011.03]
BACKGROUND: This analysis aimed to identify an operational, clinically relevant definition of response achieved in short-term clinical trials to support the identification of patients with Alzheimer's disease (AD) who would benefit most from long-term galantamine therapy... CONCLUSIONS: Patients who demonstrate improvement, stability, or limited cognitive decline 2-5 months after reaching maintenance doses of galantamine are more likely to experience continued benefit from long-term galantamine therapy.

Galantamine improves sustained attention in chronic cocaine users. [2011.02]
Chronic cocaine users are known to have cognitive deficits that are predictive of poor treatment response. Whether these deficits improve with medications targeting specific cognitive functions has not been examined in previous studies.

Galantamine augmentation of long-acting injectable risperidone for cognitive impairments in chronic schizophrenia. [2011.02]
CONCLUSION: Galantamine showed no ameliorative effects on cognitive measures in this 6month, double-blind study of patients with schizophrenia treated with an assured and stable antipsychotic medication delivery system. Galantamine may not be an appropriate augmentation agent for cognitive impairments in patients with schizophrenia at the dose used. Copyright (c) 2010 Elsevier B.V. All rights reserved.

Cessation versus continuation of galantamine treatment after 12 months of therapy in patients with Alzheimer's disease: a randomized, double blind, placebo controlled withdrawal trial. [2011]
Galantamine improved symptoms in Alzheimer's disease (AD) patients after 5 to 6 months of treatment... Treatment was generally safe and well tolerated.

Clinical Trials Related to Razadyne (Galantamine)

The Use of Galantamine HBr (Reminyl) in Electroconvulsive Therapy: Impact on Mood and Cognitive Functioning [Active, not recruiting]
The purpose of the study is to see if galantamine HBr (Razadyne) is safe and can help treat problems with thinking and memory caused by electroconvulsive therapy (ECT).

Effects of Galantamine on Cognition [Recruiting]
Schizophrenia is a chronic disorder with onset of psychosis occurring in late teen early twenties, with cognitive impairments and negative symptoms frequently emerging much earlier. Such cognitive impairments and negative symptoms but much milder are also observed in high-risk groups (such as relatives of schizophrenia patients), who may or may not develop the full blown psychotic disorder. Our study plans to recruit such non-ill subjects to test the effects of galantamine on clinical/physiological/cognitive measures. This study serves several goals: If a drug is found effective in treating subtle deficits, then it will provide treatment strategy in individuals with schizophrenia spectrum personality disorders and for early intervention in schizophrenia. In addition, one of the difficulties of testing a drug on schizophrenia is that patients take other medications (i. e., antipsychotic drugs) that can change the effects of the test drug. The proposed study will be in subjects who will not be taking antipsychotic medications. Our study will be carried out in two sessions, at least one month apart. Subjects will be randomly assigned to the two possible order of administration: the drug and then placebo, or the placebo and then drug. Subjects will be given a lead-in 3 days of 4mg/ twice a day of galantamine (or placebo) followed by 8 mg (or placebo) on the 4th day, the day of testing. We will administer a battery of clinical/cognitive/neurophysiological tests after the 8 mg drug dose.

A Single Dose, Cross-Over Bioequivence Study Comparing Galantamine IR (Immediate Release) Table and Galantmine OS (Oral Solution) in Healthy Volunteers [Completed]
The purpose of this open-label, single dose, two-treatment, two-period, cross-over study is to evaluate the pharmacokinetic profile and tolerability of galantamine oral solution and galantamine tablet.

Effects of Galantamine on Smoking Abstinence [Recruiting]

Oxytocin or Galantamine Versus Placebo for the Treatment of Negative Symptoms and Cognitive Impairments in Schizophrenia [Recruiting]
The project is designed to address the following two primary aims:

1. To determine whether adjunctive oxytocin is superior to placebo for the treatment of persistent negative symptoms, as measured by the SANS total score, in people with schizophrenia.

2. To determine whether adjunctive Galantamine is superior to placebo for the treatment of cognitive impairments, as measured by improvement on a composite neurocognitive score in people with schizophrenia.

The investigators will also address the following secondary aims:

1. To determine whether people with schizophrenia treated with adjunctive oxytocin, compared to placebo, will show greater improvement on markers of negative symptom liability including: social affiliation, facial affect recognition, olfactory discrimination, initiation of smooth pursuit and latency of internally-driven saccades.

2. To determine whether people with schizophrenia treated with adjunctive Galantamine, compared to placebo, will show greater improvement on markers of cognitive impairment liability including: predictive pursuit, P50 sensory gating and visual-spatial working memory.

The investigators will address the following exploratory aims:

1. To determine whether changes in markers of negative symptom liability are correlated with changes in SANS total score.

2. To determine whether changes in markers of cognitive impairment liability are correlated with changes in the composite neurocognitive score.

3. To determine the response to oxytocin of all cognition domains assessed by the MATRICS battery, and to determine the response to Galantamine of all cognition domains assessed by the MATRICS, which are not included in the primary neurocognitive outcome score.

4. To determine whether there is a differential response of oxytocin and Galantamine on the SANS total score, composite neurocognitive score, and with the phenotypic measures of negative symptom and cognitive impairment liability.

5. To determine whether oxytocin and Galantamine are associated with:

- adverse effects on positive or depressive symptoms;

- adverse effects on motor symptoms;

- adverse effects on laboratory and EKG measures;

- increased occurrence of side effects;

- social interest that is independent of sexual desire.
