III. Assess the relative efficacy of the acellular vaccines with respect to one another.
IV. Assess the immunogenicity of acellular vs. whole-cell vaccines in the study population.
- Compare the frequency of adverse events with each vaccine. VI. Compare the frequency of adverse events attributable to the pertussis component in each of the 3 vaccines.
VII. Assess alternative laboratory diagnostic techniques for pertussis in estimating vaccine efficacy, i.e., mucosal immune response, DNA probes, or antibody response to other components of the organism.
VIII. Assess the relative efficacy estimates of each vaccine, using clinical criteria to compare the relative incidence rates in each vaccine group.
Read the detailed description
PROTOCOL OUTLINE: This is a randomized, double-blind study. Patients are stratified by participating institution and randomly assigned to 1 of 3 vaccines and a placebo vaccine in a 3:3:3:1 ratio.
One group receives diphtheria-tetanus-pertussis (DPT) vaccine containing filamentous hemagglutinin (FHA), Pt-9K/129G, and 69 kDA outer membrane protein (OMP).
A second group receives DPT containing FHA and OMP. The third group receives DPT containing whole-cell pertussis. The control group receives diphtheria-tetanus (DT) vaccine. All vaccines are administered as an intramuscular or deep subcutaneous injection at 6-12, 13-20, and 21-28 weeks of age. The first vaccine is given at week 12 if hepatitis B or other immune globulin was given at birth.
All patients receive a DT booster at 11 months, and are followed every 4 weeks for approximately 20 months.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing diphtheria-tetanus-pertussis vaccine containing whole-cell pertussis and diphtheria-tetanus vaccine in people with Pertussis, run by National Institute of Allergy and Infectious Diseases (NIAID).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
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 24 Jun 2005. 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 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.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00004800, which also lists 1 linked publication.
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 24 Jun 2005.
