About this study

Official title: Botulinum Toxin Type A Versus 0,9% Saline in Treatment of Cranial Allodynia in Patients With Headache

The objective of this study is evaluated if the Botulinum Toxin Type A is superior to 0,9% saline in treatment of cranial Allodynia in patients with headache.

Hypothesis

H(0): Botulinum Toxin Type A is not superior to 0,9% saline in treatment of cranial Allodynia in patients with headache

H (1): Botulinum Toxin Type A is superior to 0,9% saline in treatment of cranial Allodynia in patients with headache

Read the detailed description

After adequation and approve from ethics committee on research involving human the selection of patients with tension headache or migraine according to The International Classification of Headache Disorders, 2nd Edition (ICHD II) will start in the Headache Clinic of Alcides Carneiro Universitary Hospital. Those selected will be oriented regarding to the study steps and potential risks of the procedures. The patients will catalog the occurrence of headache and use of analgesics for 30 days through daily headache. At the end of this month patients will be evaluated by a physician experienced in the treatment of headache to define the occurrence of pain or allodynia of the scalp. Data gathered in this consultation will be recorded in standardized questionnaires for the study. The questionnaire is divided: Patient's identification, illustration of the pain area and allodynea points, pain intensity by Visual Analogue Scale (VAS) and finally medication use will be collected in the Headache Diary.

The people are randomized with block permutation, security of equal distribution in two groups (number previous determined). One group with 0,9% saline and the other Botulinum Toxin A.

Finishing the application by the Researcher (Who doesn't know the result of randomization and the infiltrated containing). The patients will be submit to three evaluations: the first, 30 days after infiltration, with a doctor who didn't participate of the anterior steps and will analyze the pain intensity by Visual Analogue Scale (VAS), an episode of headache and use of painkiller trough Headache Diary. The Doctor will ask to the patient localize, if exist, the allodynia points. The others evolution visit will happen 60 and 90 days after application, with this same doctor using the same methods. Another professional, who doesn't know about the anterior steps of the study, will do the statics data analyze.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Botulinum toxin type A and 0,9% saline in people with Headache and Allodynia, run by Federal University of Bahia at 1 site in Brazil.

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 2 inclusion and 6 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 23 May 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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?

Evaluate the allodynea's improvement following these criteria (time frame: six months). 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 23 May 2011.
