Randomized Trial of Alternative HPV Vaccination Schedules in Males in a University Setting

February 26, 2014 updated by: Richard Zimmerman, University of Pittsburgh

The investigators propose a randomized, open label trial of the immunogenicity of HPV vaccine among males 18-24 years old, comparing an on-time administration of the third dose with delayed administration of the third dose. All participants would receive the first and second doses according to schedule. They would be randomized to either Dose 3 at 6 months or Dose 3 at 12 months.

Hypothesis: The Geometric mean titers in the 12 month test group (T) are non-inferior to the usual timing control group (C):

H0: δ ≤ -δ0 versus H1: δ > -δ0 where δ = log (GMTT )- log (GMTC) and δ0 is the pre-specified non-inferiority margin

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

1. Specific Aims and Overview: The investigators propose a randomized, open label trial of HPV vaccine among males 18-24 years old, comparing an on-time administration of the third dose with delayed administration of the third dose. All participants would receive the first and second doses according to schedule. They would be randomized to either Dose 3 at 6 months or Dose 3 at 12 months.

Blood would be drawn for titers at twice from all participants: pre-dose 1 and one month post Dose 3.

No cytology studies or DNA studies will be conducted.

1.1 Aims:

  1. Determine if delay in the third dose is immunologically non-inferior to the standard administration schedule (1 month post-dose 3).
  2. Determine the side effect profile of a delayed third dose, in comparison to the standard schedule.
  3. Determine the preference and compliance of the men for the timing of the third dose.

1.2 Hypothesis for non- inferiority:

The GMTs in the test group (T) are non-inferior to the usual timing control group (C):

H0: δ ≤ -δ0 versus H1: δ > -δ0 where δ = log (GMTT )- log (GMTC) and δ0 is the pre-specified non-inferiority margin.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Immunogenicity After Dose 3
Time Frame: 1 month after dose 3 (e.g., month 7 if third dose at 6months or month 13 if third dose at 12 months)
Geometric mean titer (GMT) and 95% confidence intervals around titer 1 month after dose 3 in per protocol population, comparing the two groups.
1 month after dose 3 (e.g., month 7 if third dose at 6months or month 13 if third dose at 12 months)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Time Frame
Compliance With 3rd Dose
