Effect of Oxcarbazepine on Serum Brain Derived Neurotrophic Factor (BDNF)

Status Completed

Clinical Trial Summary

The present study has been designed to evaluate the change in serum BDNF level with oxcarbazepine monotherapy in bipolar disorder and to explore the possibility of its neuroprotective effect.

Clinical Trial Description

Bipolar disorder (BD) is a chronic psychiatric illness of partially unknown pathophysiology. BD likely involves, at a molecular and cellular level, dysfunctions of critical neurotrophic, cellular plasticity and resilience pathways and neuroprotective processes. Abnormalities of neurotrophins (NTs) and other trophic factors orchestrate important alterations which could be implicated in the etiology of BD. As consistently reported in post-mortem studies, these modifications are generally associated with the disruption of distinct subregions and functions of the brain, one of which is the deregulation of neurotrophins.

NTs are capable of signaling neurons, glial cells and other cellular systems to enable survival, differentiation and growth. BDNF is one of the most studied and abundant NTs in the brain, which plays an important role in a variety of neural processes during the development of both animals and humans. Initially, BDNF is important for neurogenesis, neuronal survival, and normal maturation of neural development pathways. In the adult, BDNF is not only important for synaptic plasticity and dendritic growth, but also for long-term memory consolidation. Several studies have proved that BDNF is significantly reduced in manic, hypomanic or depressive stages of BD, whereas euthymic patients exhibit BDNF levels similar to healthy controls.

Rafael T. de Sousa et al have observed a significant increase in serum BDNF levels after 28 days of lithium monotherapy in patients with BD and suggested neuroprotective role of lithium due to its direct regulatory effect on BDNF. Oxcarbazepine is a commonly used mood stabilizer which has demonstrated comparable efficacy to divalproate sodium and better tolerability profile but till date there is no study on its effect on BDNF. The aim of the present study is to evaluate the change in serum BDNF level with oxcarbazepine monotherapy in bipolar disorder and to explore the possibility of its neuroprotective effect. ;

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.
