About this study

Official title: A Randomized, Worldwide, Placebo-Controlled, Double-Blind Study to Investigate the Safety, Immunogenicity, and Efficacy on the Incidence of HPV 16/18-Related CIN 2/3 or Worse of the Quadrivalent HPV (Types 6, 11, 16, 18) L1 Virus-Like Particle (VLP) Vaccine in 16- to 23-Year Old Women - The FUTURE II Study (Females United to Unilaterally Reduce Endo/Ectocervical Disease)

The primary purpose of the study is to determine if GARDASIL™ (V501) is able to prevent cervical cancer.

Read the detailed description

In the 4-year Base Study (V501-015) (NCT00092534), participants were randomized in a 1:1 order to receive 3 doses of GARDASIL™ or matching placebo at Day 1, Month 2, and Month 6 and were assessed for efficacy, immunogenicity, and safety.

In the Base Study Extension (EXT) [V501-015-10], participants who received placebo or only 1 dose of GARDASIL™ in the Base Study, were given 3 doses of open-label GARDASIL™ at EXT Day 1, EXT Month 2, and EXT Month 6, and were followed to EXT Month 7. Participants who who received 2 doses of GARDASIL™ in the Base Study were given 1 dose of GARDASIL™ at EXT Day 1 and were followed for 15 days (day of vaccination plus 14 days).

In the 10-year Base Study Long-Term Follow-Up (LTFU) [V501-015-21] the effectiveness, immunogenicity and safety of GARDASIL™ was assessed during a period of 10 years following completion of the Base Study (V501-015) [14 years after the first dose of GARDASIL™] and, for some measures, the Base Study EXT (V501-015-10) [10 years after the first dose of GARDASIL™]. Participants from Denmark, Iceland, Norway and Sweden who participated in the Base Study were eligible to enroll in the LTFU. Effectiveness and safety was assessed by registry-based follow-up, and immunogenicity was assessed by serological testing at approximately Year 5 and Year 10 of the V501-015-21 LTFU.

An 8-year extension was added to the LTFU (V501-015-22] to continue the evaluation of the long-term effectiveness and immunogenicity of GARDASIL™. Effectiveness and safety will be assessed by registry-based follow-up, and immunogenicity will be assessed by serological testing at approximately Year 4 and Year 8 of the extension of the LTFU.

What is being measured

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

  1. Incidence of the Composite Endpoint of Human Papillomavirus (HPV) 16/18-related Cervical Intraepithelial Neoplasia (CIN) 2 or Worse in the Base Study

    This measure is defined to have occurred when, on a single cervical biopsy, endocervical curettage (ECC), loop electrosurgical excision procedure (LEEP), or conization specimen, there was HPV Vaccine consensus diagnosis of CIN 2 or worse up to 4 years after the first vaccination. For this measure, CIN 2 or worse includes CIN 2, CIN 3, adenocarcinoma in situ (AIS) or cervical cancer related to HPV 16 or 18.

    Measured: Up to 4 years

  2. Incidence of the Composite Endpoint of Human Papillomavirus (HPV) 16/18-related Cervical Intraepithelial Neoplasia (CIN) 2 or Worse in the Long-term Follow-up (LTFU) Study

    This measure is defined to have occurred when, on a single cervical biopsy, endocervical curettage (ECC), loop electrosurgical excision procedure (LEEP), or conization specimen, there was HPV Vaccine Nordic pathology panel (NPP) consensus diagnosis of CIN 2 or worse up to 14 years after the first vaccination. For this measure, CIN 2 or worse includes CIN 2, CIN 3, AIS or cervical cancer related to HPV 16 or 18. Only participants who received qHPV vaccine during the Base Study vaccination period and consented for inclusion in the LTFU are included. Because the objective was to demonstrate qHPV vaccine prophylactic efficacy at 14 years, Cohort 2 was not included in the analysis.

    Measured: Up to 14 years since Vaccine Dose 1

  3. Incidence of the Composite Endpoint of HPV16/18-related CIN 2 or Worse in the Long-term Follow-up (LTFU) Study

    This measure is defined to have occurred when, on a single cervical biopsy, ECC, LEEP, or conization specimen, there was HPV Vaccine NPP consensus diagnosis of CIN 2 or worse up to 22 years after the first vaccination. For this measure, CIN 2 or worse includes CIN 2, CIN 3, AIS or cervical cancer related to HPV 16 or 18. Only participants who received qHPV vaccine during the Base Study vaccination period and consented for inclusion in the LTFU will be included.

    Measured: up to 22 years post Vaccination Dose 1

Secondary outcomes (19)

  1. Number of Participants With Anti-Human Papillomavirus (HPV) 6 Titer ≥20 mMU/mL Based on Competitive Luminex Immunoassay (cLIA) in the Base Study

    Anti-HPV levels >20 mMU/mL neutralize a large input load of HPV 6 pseudovirions in vitro; thus, the number of participants with anti-HPV 6 ≥20 mMU/mL 4 four weeks after the third quadrivalent HPV (qHPV) or placebo vaccination in the Base Study was determined.

  2. Number of Participants With Anti-Human Papillomavirus (HPV) 11 Titer ≥16 mMU/mL Based on Competitive Luminex Immunoassay (cLIA) in the Base Study

    Anti-HPV levels >20 mMU/mL neutralize a large input load of HPV 11 virions in vitro; thus, the number of participants with anti-HPV 11 ≥16 mMU/mL 4 four weeks after the third quadrivalent HPV (qHPV) or placebo vaccination in the Base Study was determined.

    Measured: Week 4 Postdose 3

  3. Number of Participants With Anti-Human Papillomavirus (HPV) 16 Titer ≥20 mMU/mL Based on Competitive Luminex Immunoassay (cLIA) in the Base Study

    Anti-HPV levels >20 mMU/mL neutralize a large input load of HPV 16 pseudovirions in vitro; thus, the number of participants with anti-HPV 16 ≥20 mMU/mL 4 four weeks after the third quadrivalent HPV (qHPV) or placebo vaccination in the Base Study was determined.

    Measured: Week 4 Postdose 3

  4. Number of Participants With Anti-Human Papillomavirus (HPV) 18 Titer ≥24 mMU/mL Based on Competitive Luminex Immunoassay (cLIA) in the Base Study

    Anti-HPV levels >20 mMU/mL neutralize a large input load of HPV 18 pseudovirions in vitro; thus, the number of participants with anti-HPV 18 ≥24 mMU/mL 4 four weeks after the third quadrivalent HPV (qHPV) or placebo vaccination in the Base Study was determined.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Gardasil, human papillomavirus (type 6, 11, 16, 18) recombinant vaccine in people with Cervical Cancer and Genital Warts, 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 8 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 1 Aug 2025. 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 26 Nov 2009). 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?

Incidence of the Composite Endpoint of Human Papillomavirus (HPV) 16/18-related Cervical Intraepithelial Neoplasia (CIN) 2 or Worse in the Base Study (time frame: Up to 4 years). The study lists 3 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 NCT00092534, which also lists 33 linked publications.

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 1 Aug 2025.
