Trial summary

There's high incidence of seborrhic dermatitis among patients suffering from Parkinson's disease. Seborrhic dermatitis is caused by increased exertion of sebaceous glands. Previous studies have shown an increase of sebum excretion rate in parkinsonian pateints. Read more about this study

About this study

There's high incidence of seborrhic dermatitis among patients suffering from Parkinson's disease. Seborrhic dermatitis is caused by increased exertion of sebaceous glands. Previous studies have shown an increase of sebum excretion rate in parkinsonian pateints. Other studies demonstrated improvement in seborrhic dermatitis after anticholinergic treatment. From these studies we concluded that there might be hyperactivity of the parasympathetic system among PD patients, that cause increased exertion of sebum, therefore local injection of botulinium toxin, which inhibitis acetyl choline realese, might improve the rash of seborrhic dermatitis.

40 patients suffering from Parkinson disease or other parkinsonian disorders will participate in this study.

Before treating the patients with botulinium toxin, we will measure the sebum exertion with the sebumeter device and make clinical evaluation of the rash. We will also take a picture of the rash.

Then Botulinium toxin (60- 100 units) will be locally injected to the rash area.

Two weeks after the injection the patients will be called and evaluated clinicly and by the sebumeter. Then they will be checked again after 3 weeks, after a month and after two, three and four month's.

Exclusion criteria:

  • Dementia
  • Renal or liver failure
  • Pregnancy or breast feeding
  • History of allergy to botolinium toxin
  • Motor neuron disease or any other disease that insult the neuromuscular junction
  • Treatment with Amynoglycoside antibiotic. This study will include only patients that can give informed concent.

SEBUMETER SM 810- this is the device we will use to measure sebum exertion before and after injecting botulinium toxin. The measurement is based on grease-spot photometry. A special tape becomes transparent in contact with the sebum on the skin surface. For the determination of the sebum, the measuring head of the cassette is inserted into the aperture of the device, where the transparency is measured by a light source sending light through the tape which is reflected by a little mirror behind the tape. A photocell measures the transparency. The light transmission represents the sebum content on the surface of the measuring area. A microprocessor calculates the result, which is shown on the display in µg sebum/cm² of the skin.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Botulinum toxin in people with Parkinson Disease and Parkinsonism, run by Rabin Medical Center.

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 1 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: status not confirmed, as of the sponsor's last update on 7 Oct 2008. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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?

Clinical assesment of the rash Photometric test of sebum exertion (time frame: 4 month). 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 7 Oct 2008.
