Brief Summary
People with chronic kidney disease are known to have immune response abnormalities, including a diminished response to some vaccinations. Those with chronic kidney disease have a disproportionate burden of HPV 6-, 11-, 16- and/or 18-related genital tract disease. Due to immune response abnormalities, the CKD population may or may not respond to the recommended three-dose regimen of Gardasil®, a vaccine intended to protect against HPV 6-, 11-, 16-, and 18-related genital tract disease. The objective of this study is to measure the antibody response to Gardasil® in female patients 9-21 years of age with chronic kidney disease (CKD) (Stage 1-4), end-stage kidney disease (Stage 5 CKD), and status-post kidney transplant. Gardasil® vaccine will be administered according to the FDA-approved schedule. Blood samples to measure antibody levels to vaccine strains of human papillomavirus (HPV) will be obtained at months 0, 7 and 24.

Outcome Measures
Primary Outcomes (6)
Percentage of Patients 9-15 Years of Age With CKD Achieving Seropositivity (IgG Assay) at Blood Draw 2
The primary outcome was antibody response to each of four HPV genotypes contained within the HPV vaccine at the time periods specified for the blood draws. Antibody levels, measured by Merck GmbH, were initially determined using the competitive Luminex immunoassay(cLIA; Merck GmbH), the assay used in the original licensing studies. Seropositivity was defined as being above thresholds set at 20, 16, 20, and 24 milliMerck units for HPV genotypes 6, 11, 16, and 18, respectively, as determined in phase 2 studies among patients who were immunocompetent. Antibody levels were reanalyzed using the newer, more sensitive IgG cLIA in stored serum from blood draws 2 and 3. Seropositivity for this assay was defined as being above thresholds set at 15, 15, 7, and 10 milliMerck units for HPV genotypes 6, 11, 16, and 18, respectively.

Study Arms (3)
1. Chronic Kidney Disease, NKF Stage 1-4
OTHERGardasil vaccine series will be administered according to FDA-approved schedule, as recommended by the Centers for Disease Control and Prevention and the American Academy of Pediatrics. Geometric antibody titers among those with chronic kidney disease will be compared to titers in the general population measured during Phase III clinical studies by Merck \& Co, Inc, to prove efficacy of the vaccine and obtain FDA approval.
2. ESRD (dialysis)
OTHERGardasil vaccine series will be administered according to FDA-approved schedule, as recommended by the Centers for Disease Control and Prevention and the American Academy of Pediatrics. Geometric antibody titers among those with ESRD will be compared to titers in the general population measured during Phase III clinical studies by Merck \& Co, Inc, to prove efficacy of the vaccine and obtain FDA approval.
3. Kidney Transplant Recipient
OTHERGardasil vaccine series will be administered according to FDA-approved schedule, as recommended by the Centers for Disease Control and Prevention and the American Academy of Pediatrics. Geometric antibody titers among those with a kidney transplant will be compared to titers in the general population measured during Phase III clinical studies by Merck \& Co, Inc, to prove efficacy of the vaccine and obtain FDA approval.
Interventions
Standard Gardasil® 3-dose regimen (0.5 mL/dose; doses at 0, 2 and 6 months) delivered to females with chronic kidney disease 9-21 years of age.
Eligibility Criteria
You may qualify if:
- Females, aged 9-21 years, in the following groups:
- CKD (defined as estimated glomerular filtration rate between 90 ml/min/1.73m2 and 15 ml/min/1.73m2, as calculated by the Schwartz formula)
- ESRD (eGFR \< 15 ml/min/1.73m2, or receiving chronic dialysis \[peritoneal or hemodialysis\])
- Status-post kidney transplant
You may not qualify if:
- Within first 3 months post kidney transplant
- Within 3 months of kidney rejection episode
- Hypersensitivity to active substances or excipients of Gardasil vaccine
