Gardasil (Human Papillomavirus Vaccine) - Summary

 
 



GARDASIL SUMMARY

GARDASIL, Human Papillomavirus Quadrivalent (Types 6, 11, 16, and 18) Vaccine, Recombinant, is a non-infectious recombinant quadrivalent vaccine prepared from the purified virus-like particles (VLPs) of the major capsid (L1) protein of HPV Types 6, 11, 16, and 18.

GARDASIL is indicated for the following:

Girls and Women

GARDASIL«1 is a vaccine indicated in girls and women 9 through 26 years of age for the prevention of the following diseases caused by Human Papillomavirus (HPV) types included in the vaccine:

  • Cervical, vulvar, and vaginal cancer caused by HPV types 16 and 18
  • Genital warts (condyloma acuminata) caused by HPV types 6 and 11

And the following precancerous or dysplastic lesions caused by HPV types 6, 11, 16, and 18:

  • Cervical intraepithelial neoplasia (CIN) grade 2/3 and Cervical adenocarcinoma in situ (AIS)
  • Cervical intraepithelial neoplasia (CIN) grade 1
  • Vulvar intraepithelial neoplasia (VIN) grade 2 and grade 3
  • Vaginal intraepithelial neoplasia (VaIN) grade 2 and grade 3
Boys and Men

GARDASIL is indicated in boys and men 9 through 26 years of age for the prevention of genital warts (condyloma acuminata) caused by HPV types 6 and 11.

Limitations of GARDASIL Use and Effectiveness

The health care provider should inform the patient, parent, or guardian that vaccination does not eliminate the necessity for women to continue to undergo recommended cervical cancer screening. Women who receive GARDASIL should continue to undergo cervical cancer screening per standard of care. [See Patient Counseling Information.]

GARDASIL has not been demonstrated to provide protection against disease from vaccine and non-vaccine HPV types to which a person has previously been exposed through sexual activity. [See Clinical Studies (14.3, 14.4).]

GARDASIL is not intended to be used for treatment of active external genital lesions; cervical, vulvar, and vaginal cancers; CIN; VIN; or VaIN.

GARDASIL has not been demonstrated to protect against diseases due to HPV types not contained in the vaccine. [See Clinical Studies.]

Not all vulvar and vaginal cancers are caused by HPV, and GARDASIL protects only against those vulvar and vaginal cancers caused by HPV 16 and 18.

GARDASIL does not protect against genital diseases not caused by HPV.

Vaccination with GARDASIL may not result in protection in all vaccine recipients.

Clinical Trials Related to Gardasil (Human Papillomavirus Vaccine)

A Clinical Trial to Study the Safety, Tolerance and Immunogenic Response to Gardasil and rLP2086 Vaccine When Given at the Same Time to Children Between the Ages of 11 and 17 [Not yet recruiting]
This is a clinical study to assess the safety, tolerance and immunogenic response to Gardasil (human papilloma virus (HPV)) and rLP2086 vaccine. Healthy male and female subjects will be randomized into 1 of 3 groups; the trial will be an observer-blinded study to the injection being given; and, vaccinated with either Gardasil and rLP2086 concomitantly, rLP2086 and saline concomitantly, or Gardasil and saline concomitantly. The subjects are adolescent children between the ages of 11 and 17 years old.

Study to Determine if Gardasil Vaccine is Safe and Effective in Lupus Patients [Not yet recruiting]
Cervical neoplasia is increased in women with SLE most likely due to cervical infection with human papilloma virus (HPV). 70% of cervical cancer is caused by HPV types 16 and 18. Gardasil vaccine prevents cervical infection with HPV types 16 and 18. Thus lupus patients (who are susceptible to cervical cancer) may benefit from getting Gardasil vaccine which can prevent cervical cancer. Vaccines are generally safe and efficacious in SLE but no studies have been done on the use of this vaccine in SLE. The investigators hypothesize that Gardasil vaccine is safe and effective in SLE. This study will look at vaccine safety in patients with mild to moderate and minimally active or inactive SLE and measure how well they make protective antibodies after receiving the vaccine. In other words this will check how well the vaccine works in SLE.

Immunogenicity and Safety of HPV Vaccine Gardasil in Young Women [Not yet recruiting]
The purpose of this study is to evaluate the immunogenicity and safety of the HPV vaccine Gardasil in young women.

A Phase I Trial of Safety and Immunogenicity of Gardasil(Registered Trademark) Vaccination Post Stem Cell Transplantation in Patients With and Without Immunosuppression [Recruiting]
Background:

- Gardasil(Registered Trademark), a recently approved vaccine for the sexually

transmitted human papillomavirus (HPV), provides immunity to four types of HPV that are associated with genital warts and cervical, vaginal, and vulvar precancer and cancer. The vaccine has been shown to be highly effective in preventing infection with these HPV types and was approved for use by the Food and Drug Administration.

- More research is needed about the vaccine's ability to induce immunity in individuals

with suppressed immune systems, such as those who have had other kinds of cancer treatment such as stem cell transplant. Genital warts, precancer, and cancer have been reported as a late complication after stem cell transplant. Researchers are interested in determining whether the HPV vaccine is safe to give and able to induce immunity in female stem cell transplant recipients, their female donors, and healthy female volunteers.

Objectives:

- To assess the safety and immune response of the HPV vaccine in female recipients of stem

cell transplants who are either off or on stable doses of immunosuppression.

Eligibility:

- Females between 18 and 45 years of age who have had allogenic stem cell transplants.

- Healthy female volunteers, including stem cell donors, are also eligible for this

study.

Design:

- Participants will be screened with a physical examination, blood and urine tests, and

saliva samples, and will be asked to complete a sexual quality of life questionnaire.

- Sexually active participants will also have a routine gynecologic evaluation.

- Participants will receive three HPV vaccinations according to the standard vaccination

schedule (with the second and third following 2 and 6 months after the first). Participants will record their daily temperature and any reactions to the vaccine on a vaccine report card for 1 week after each vaccination.

- Participants will have clinic visits for further testing 2, 6, 7, and 12 months after

receiving the first HPV vaccine.

Immunogenicity to Human Papillomavirus Vaccine (Gardasil) Among IBD Patients on Immunosuppressive Therapy [Recruiting]
Many IBD patients take immunosuppressive agents and we are uncertain as to their capacity to mount a truly protective response after vaccination. If IBD patients do not have an adequate immunological response, they may need to increase the dosage or get booster shots. Many clinicians who treat patients with autoimmune diseases are asking if the vaccine is safe and effective. Thus, this study has important clinical and public health significance because more than one million people in the United States who have been diagnosed with IBD.

There is not much studied about HPV and immunocompromised patients. Research on healthy women who were immunized with a set of three HPV vaccines demonstrated significantly increased antibody titers. In addition, they had significantly reduced HPV incident and persistent infection and HPV-related disease (cervical, vulvar, and vaginal cancers, cervical intraepithelial neoplasia, genital warts) through five years of follow-up compared to controls who received a placebo. The HPV vaccine was well tolerated without significant side effects.

The aims of this research are to measure the immune response in 9-26 year old IBD patients who are on immunosuppressive agents after receiving the HPV vaccine compared with controls. We will also evaluate the number and type of vaccine-associated adverse events as well as the disease activity and flare-ups that occur after each dose of vaccine. We hypothesize that IBD patients on immunosuppressive therapy will have an equivalent immune response to HPV types 6, 11, 16 and 18 at one month postdose 3 compared to healthy age-matched historical controls.

The patient population includes IBD patients who are on immunosuppressive medications. Recruiting approximately 100 patients will provide adequate power for the study. A blood sample will be taken from all IBD patients to evaluate baseline antibody levels and markers (e. g., ESR, CBC, albumin) before or immediately after immunization with the HPV vaccine. Lab tests will be redrawn at 7 months to evaluate the level of antibody titers and follow the markers. During the study, we will track basic laboratory measures, disease status by using the Pediatric Crohn's Disease Active Index or Harvey-Bradshaw Index for UC, side effects from the vaccinations, and other adverse events.
