Efficacy of Memantine add-on in the Treatment of Bipolar Disorder (Type I)

Status Recruiting

Clinical Trial Summary

The main goal of this study is evaluate the efficacy of memantine association on the treatment with a previous combination of two drugs, including quetiapine with lithium or quetiapine with aripiprazole in young patients with bipolar disorder type 1 non-responders or partial responders to that combination of drugs and evaluate the impact of this association at the cognitive functioning of the patients.

Clinical Trial Description

Current evidence suggests that deregulation of brain glutamatergic neurotransmission is involved in the pathophysiology of bipolar disorder and that drugs that intervene in this transmission may be therapeutic weapons in addressing the symptoms and cognitive deficits of this pathology. Among these drugs, particularly memantine is a strong candidate in view of their efficacy in antagonizing N-methyl-D-aspartate (NMDA) receptors, and their good safety and tolerability profile. The principal aim of this study is to evaluate the efficacy of memantine association with treatment with a combination of two drugs, including quetiapine with lithium and quetiapine with aripiprazole in young patients with bipolar disorder type 1 non-responders or partial responders and evaluate the impact of this association cognitive functioning of patients. An experimental study, randomized, double-blind, bipolar patients with type 1, of both sexes, aged 18 to 40, ambulatory or hospitalized, at any stage of the disease, seeking treatment in the Mood Disorders Program (GRUDA) of Institute os Psychiatry (IPq) of Sao Paulo University (FMUSP). Patients will come from ARIQUELI Project (Missio, G. et al, 2013 submitted Trial registration - ClinicalTrials.gov Identifier:. NCT01710163).

The study will be conducted in two stages: I - initial administration of memantine or placebo for 8 weeks; II - Maintenance administration for more 4 months. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
