  • Absence of long-term remissions of asthma (lasting more than 1 month)
  • Poorly controlled asthma, due to various reasons.
  • Patients with a FEV1 reversibility of at least 12% from initial level after 400 mcg salbutamol inhalation (4 puffs of salbutamol MDI, 100 mcg per puff). Patients whose FEV1 reversibility was 12% within the past 12 months are acceptable, providing that the records are available to the investigator.
  • Patients able to swallow capsules, able to understand and complete diary cards and to record their PEFR using a peak-flow meter.

Who cannot join

  • History or presence of cardiovascular, renal, neurologic, psychiatric, liver, immunologic, endocrine, infection or other diseases or dysfunctions if they are clinically significant. A clinically significant disease is defined as one which in the opinion of the investigator may either put the patient at risk because of participation in the study or a disease which may influence the results of the study or the patient's ability to participate in the study.
  • Patients with a recent history (< 1 year) of myocardial infarction and/or (< 3 years) of heart failure or patients with any cardiac arrhythmia requiring drug therapy.

  • Patients with clinically significant abnormal baseline haematology, blood chemistry or urinalysis or if the abnormal defines a disease listed as an exclusion criterion.
  • Patients with known allergy, side effects, intolerance/hypersensitivity to investigational drug
  • Patients currently using MAO inhibitors, tricyclic antidepressants, antiepileptic drugs, narcotic agents.

About this study

Official title: Randomised, Placebo Controlled, Double Blind, Parallel Group 3-Months Study of Sodium Valproate Efficacy in Asthma Therapy

The purpose of this study is to determine whether antiepileptic drug sodium valproate is effective in the treatment of chronic asthma.

Read the detailed description

Effective therapy of asthma still remains quite serious problem. According GINA definition, asthma is an inflammatory disorder. Consequently, modern pharmacotherapy of asthma provides wide use of anti-inflammatory drugs. But asthma also is a paroxysmal disorder: many specialists and even some guidelines underline paroxysmal clinical picture of asthma. Besides this, according to some authors, neurogenic inflammation may play important role in asthma mechanism. But some other neurogenic inflammatory paroxysmal disorders exist, and they are migraine and trigeminal neuralgia. Some antiepileptic drugs, like carbamazepine and valproate, are very effective in therapy of migraine and trigeminal neuralgia - more than in 80% of cases. If bronchial asthma also is paroxysmal inflammatory disease, like migraine and trigeminal neuralgia, it is possible that some antiepileptic drugs also are very effective in asthma therapy.

We performed a double-blind, placebo-controlled 3-month trial for evaluation of sodium valproate efficacy in therapy of bronchial asthma. Sodium Valproate is antiepileptic drug of new generation, initially produced by Sanofi Pharma. Comparison: Patients received investigational drug in addition to their usual routine antiasthmatic treatment, compared to patients received placebo in addition to their usual routine antiasthmatic treatment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. At 3 months of treatment: Change from baseline of the FEV1 and PEFR (also %predicted); Number of patients without asthma symptoms

Secondary outcomes (1)
  1. At 3 months of treatment: FEV1 before and after salbutamol inhalation; Difference in PEF pm-am (in %); The daily (daytime and night-time) symptoms scores; % of symptom free days during the treatment period; Use of other antiasthmatic medication

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Sodium Valproate in people with Bronchial Asthma, run by Centre of Chinese Medicine, Georgia.

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 10 inclusion and 11 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 19 Feb 2009. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

At 3 months of treatment: Change from baseline of the FEV1 and PEFR (also %predicted); Number of patients without asthma symptoms. 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 19 Feb 2009.
