Gardasil 9 Vaccine in Preventing HPV Infection in Patients With Hematologic Malignancies Undergoing Donor Stem Cell Transplant

May 18, 2026 updated by: M.D. Anderson Cancer Center

Human Papillomavirus Antibody Response After GARDASIL 9 Vaccination in Patients After Allogeneic Stem Cell Transplantation

This phase IV trial studies how well Gardasil 9 vaccine works in preventing human papillomavirus (HPV) infection in patients with hematologic malignancies who are undergoing donor stem cell transplant. Vaccines, such as Gardasil 9, may help the body build an effective immune response to kill cancer cells.

Detailed Description

PRIMARY OBJECTIVES:

I. To determine the immunogenicity of recombinant human papillomavirus nonavalent vaccine (GARDASIL 9) administered after allogeneic stem cell transplant (SCT) in patients with hematologic malignancy by comparing HPV 9-plex competitive Luminex immunoassay (9-plex cLIA) titers before and after GARDASIL 9 administration.

II. To evaluate the safety and tolerability of GARDASIL 9 administered after allogeneic SCT in patients with hematologic malignancy.

OUTLINE:

Patients undergo standard of care allogeneic stem cell transplant. 6-12 months following transplant, patients receive recombinant human papillomavirus nonavalent vaccine intramuscularly (IM) on day 0 and at 2 and 6 months in the absence of disease progression or unacceptable toxicity.

After completion of study intervention, patients are followed up within 3 days.

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.

Ages Eligible for Study

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
Antibody response defined as numerically elevated antibody titer of any type at 1 month post-dose 3 (month 7)
Time Frame: At 1 month post-dose 3
Antibody response at 1 month post-dose 3 (month 7) will be compared with baseline antibody level. The study will use results from the 9-plex competitive Luminex immunoassay (9-plex cLIA) test to estimate the antibody response rate at dose 3 with 95% confidence interval (CI). Will apply Student t-test/Wilcoxon test to compare continuous variables between patients who obtained antibody response as defined in the primary endpoint (responders) and those who did not respond (non-responders), and the chi-square test or the Fisher's exact test to assess the association between response status and patients' demographic and clinical characteristics. Logistic regression analysis will be used to assess the multivariate relationship between patient demographic and clinical characteristics on the probability of antibody response.
At 1 month post-dose 3

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.
Outcome Measure
Measure Description
Time Frame
Incidence of adverse events graded according to Common Terminology Criteria for Adverse Events (CTCAE) version 4.03
Time Frame: Up to 3 days post-intervention
Safety and tolerability of recombinant human papillomavirus nonavalent vaccine measured by occurrence of grade >= 3 adverse events (AEs) that are possibly, probably, or definitely related to recombinant human papillomavirus nonavalent vaccine for all 3 vaccine administrations. The study will report the AE rate with a corresponding upper bound of a 1-sided 95% CI.
Up to 3 days post-intervention
Antibody persistence at 6 months post-dose 3
Time Frame: At 6 months post-dose 3
Antibody persistence at 6 months post-dose 3 will be compared with 1 month post-dose 3. The study will apply a paired t-test with noninferiority hypotheses.
At 6 months post-dose 3
Human papillomavirus (HPV) vaccination completion rate
Time Frame: Up to 3 days post-intervention
The study will calculate the proportion of patients who are able to complete the 3 shot series of HPV vaccination. Will describe them in terms of demographics, and clinical characteristics.
Up to 3 days post-intervention
Estimation of antibody titers
Time Frame: At 6-12 months post-transplant, and at 1 and 6 months post-dose 3
Antibody titer will be measured repeatedly by the 9-plex cLIA test. Appropriate transformation (e.g. log transformation) of antibody titer will be used in the analyses to satisfy the normality assumption of linear or linear mixed effect model. Geometric mean titers will be used to summarize antibody titer at each time point. Linear mixed effect models for repeated measures analysis will be employed to assess change in antibody titer over time and to compare antibody titer change over time between different patient groups adjusting for other important covariates including disease characteristics (tumor stage, site, pathology), and other patient prognostic factors. Interaction between time and patients' characteristics on the change of antibody titer will be also investigated.
At 6-12 months post-transplant, and at 1 and 6 months post-dose 3
