About this study

Official title: Evaluation of Safety and Immunogenicity of GARDASIL™ in Healthy Females Between 9 and 26 Years of Age in SubSaharan Africa

The study is designed to determine the safety, tolerability and immunogenicity of a 3-dose regimen of GARDASIL™ administered to healthy females between 9 and 26 years of age, in Sub-Saharan Africa. Data from the current study are needed in order to complement existing extensive safety data from the GARDASIL™ clinical trials program, and confirm that GARDASIL™ may be administered safely and will induce immune responses in populations from and living in Sub-Saharan Africa, as GARDASIL™ has not previously been studied in this region of the world.

Read the detailed description

In Phase A of the study, healthy females between 9 and 12 years of age will be randomized (4:1) to receive the 3-dose regimen of GARDASIL™ or placebo, and those between 13 and 26 years old will receive GARDASIL™. In Phase B of the study, participants who received placebo in Phase A will have the option to receive the 3-dose regimen of GARDASIL™.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants Who Seroconvert to Human Papillomavirus (HPV) Type 6

    Seroconversion was defined as achieving an anti-HPV Type 6 competitive Luminex Immunoassay (cLIA) level of >=20 milli Merck U/mL. The dilution-corrected limit of detection for the Type 6 cLIA was 4.2 milli Merck U/mL.

    Measured: Month 7 (1 month postdose 3 in study Phase A)

  2. Number of Participants Who Seroconvert to HPV Type 11

    Seroconversion was defined as achieving an anti-HPV Type 11 cLIA level of >=16 milli Merck U/mL. The dilution-corrected limit of detection for the Type 11 cLIA was 3.9 milli Merck U/mL.

    Measured: Month 7 (1 month postdose 3 in study Phase A)

  3. Number of Participants Who Seroconvert to HPV Type 16

    Seroconversion was defined as achieving an anti-HPV Type 16 cLIA level of >=20 milli Merck U/mL. The dilution-corrected limit of detection for the Type 16 cLIA was 9.7 milli Merck U/mL.

    Measured: Month 7 (1 month postdose 3 in study Phase A)

  4. Number of Participants Who Seroconvert to HPV Type 18

    Seroconversion was defined as achieving an anti-HPV Type 18 cLIA level of >=24 milli Merck U/mL. The dilution-corrected limit of detection for the Type 18 cLIA was 5.8 milli Merck U/mL.

    Measured: Month 7 (1 month postdose 3 in study Phase A)

  5. Number of Participants With Injection-site Adverse Experiences

    Participants were prompted to report injection-site experiences of pain, erythema, or swelling and were also asked to report any other injection-site adverse experiences

    Measured: Up to Day 5 after any vaccination in study Phase A

  6. Number of Participants With Elevated Temperature (Oral Temperature >=100 °F)

    Measured: Up to Day 5 after any vaccination in study Phase A

  7. Number of Participants With Serious Adverse Experiences

    A serious adverse experience is any adverse experience that results in death, is life threatening, results in persistent or significant disability/incapacity, results in or prolongs existing inpatient hospitalization, is a congenital anomaly/birth defect, is a cancer, is an overdose, or is another important medical event that may jeopardize the participant and may require medical or surgical intervention

    Measured: From the time of informed consent is signed through the last study visit (up to 19 months)

Secondary outcomes (4)
  1. Geometric Mean Titer (GMT) of Anti-HPV Type 6 Antibody

    Anti-HPV Type 6 antibodies were measured by cLIA. The seropositive cut-off threshold for this assay is defined as 20 milli Merck U/mL.

    Measured: Month 7 (1 month postdose 3 in study Phase A)

  2. GMT of Anti-HPV Type 11 Antibody

    Anti-HPV Type 11 antibodies were measured by cLIA. The seropositive cut-off threshold for this assay is defined as 16 milli Merck U/mL.

    Measured: Month 7 (1 month postdose 3 in study Phase A)

  3. GMT of Anti-HPV Type 16 Antibody

    Anti-HPV Type 16 antibodies were measured by cLIA. The seropositive cut-off threshold for this assay is defined as 20 milli Merck U/mL.

    Measured: Month 7 (1 month postdose 3 in study Phase A)

  4. GMT of Anti-HPV Type 18 Antibody

    Anti-HPV Type 18 antibodies were measured by cLIA. The seropositive cut-off threshold for this assay is defined as 24 milli Merck U/mL.

    Measured: Month 7 (1 month postdose 3 in study Phase A)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Quadrivalent Human Papillomavirus (Types 6, 11, 16, 18) Recombinant Vaccine (GARDASIL™) in people with Papillomavirus Infections, run by Merck Sharp & Dohme LLC.

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 6 inclusion and 19 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 14 Nov 2018. 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. 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?

Yes. Results are posted in the registry (first posted 3 Jun 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants Who Seroconvert to Human Papillomavirus (HPV) Type 6 (time frame: Month 7 (1 month postdose 3 in study Phase A)). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01245764, 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 14 Nov 2018; AzTrials last refreshed its copy on 8 Nov 2026.
