About this study

Official title: Diagnostic Immunization With Rabies Vaccine in Patients With Primary Immunodeficiency Disorders

The purpose of this study is to evaluate diagnostic immunization protocol of rabies vaccine for diagnosis the patients with primary immunodeficiency disorders and study humoral and cellular immune response to rabies vaccine in patients with primary immunodeficiency.

Read the detailed description

Objective Primary objective

: To study diagnostic immunization protocol of rabies vaccine for diagnosis the patients with primary immunodeficiency disorders. Secondary objective

  • To study humoral and cellular immune response to rabies vaccine in patients with primary immunodeficiency.
  • To study anti-rabies immunization protocol in patients with primary immunodeficiency disorders.

Population Case group: Twenty primary immunodeficiency disease patients that are diagnosed, treated and followed at Allergy and Immunology unit, Department of Pediatrics, Faculty of Medicine, Chulalongkorn University.

Control group: Twenty healthy subjects who have no underlying disease and age-matched with case patients. Inclusion and exclusion criteria

Vaccine :

  • Verorab® (PVRV; Purified Vero Cell Vaccine) 0.5 ml intramuscular
  • Standard intramuscular regimen: ESSEN on days 0, 3, 7, 14, 28 and booster at 1 year later on days 360 and 363

Immunological evaluations :

  1. Humoral immune response : on 5 ml blood samples will be collected for antibody determination days 0, 14, 28, 90, 360, 367 and 374. Neutralizing antibodies will be determined blindly using the rapid fluorescent focus inhibition test (RFFIT) at Queen Saovabha Memorial Institute. Rabies neutralizing antibody will be reported in IU/ml The protective antibody level are defined rabies neutralizing antibody ≥ 0.5 IU/ml .
  2. Cellular mediated immune response :

On 5 ml blood samples will be collected for antibody determination days 14, 28, 90, 360, 367 and 374. Lymphocyte proliferation response to rabies antigen will be determined by using 3H-thymidine incorporation assay.

The responder criteria are defined as stimulation index (SI index) ≥ 2.0 was considered as evidence of antigen-induced lymphocyte proliferation.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Verorab® (PVRV; Purified Vero Cell Vaccine) in people with Primary Immunodeficiency, run by Chulalongkorn University at 1 site in Thailand.

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 12 inclusion and 4 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 Jul 2015. 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 Thailand. 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. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Narissara - Suratannon, MD (6622564455 ext. 14,15, mayzped@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Rabies neutralizing antibody titer (RFFIT test) (time frame: 1 year). 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 Jul 2015.
