Uno studio clinico esplorativo in aperto che valuta l'immunogenicità del regime di vaccinazione HPV a 2 dosi 9-valente
Uno studio clinico in aperto che valuta l'immunogenicità del regime di vaccinazione 9vHPV per oltre 6 mesi tra donne di età compresa tra 16 e 45 anni, uno studio esplorativo sull'immunogenicità
The goal of this study is to explore and evaluate whether a 2-dose schedule of Gardasil 9 among young and mid-adult women 16-45 years of age is generally safe and immunogenic, with an antibody response that is not inferior to that observed of a 3-dose schedule of Gardasil 9 among women aged 16-26 years old. The investigators thought that having a 2-dose vaccination regimen for individuals 16 to 45 would provide a more robust dataset than those of 27 to 45 years old.

Descrizione dettagliata
The investigators will identify potential eligible subjects from the Boston Medical Center (BMC) Clinical Data Warehouse from the following BMC clinics: Pediatrics, Adolescent Medicine, Family Medicine, Obstetric/ Gynecology (OB/GYN), and Women's Health/Adult Primary Care. The research team will mail a recruitment opt-out letter signed by the principal investigator to the participant along with a study flyer. The recruitment letter will inform the participant that a research member may contact them via phone within two week to provide more information regarding the study.
Participants opting-in will be called and interviewed with the study recruitment script and eligibility will be determined. Eligible participants who agree to participate (in-person or over the phone), will be scheduled to come to the Boston University (BU) General Clinical Research Unit (GCRU) to complete the consent process. At the baseline visit participants will be assigned into the appropriate group (control vs. intervention) based on their age.

Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Change in immunogenicity of Gardasil 9
Lasso di tempo: baseline and 7 months
|
Immunogenicity will be measured by serum antibodies assessed by ELISA to the nine HPV types (anti-HPV 6/11/16/18/31/33/45/ 52/58 where positive anti-HPV serum levels are defined as >30, >16, >20, >24, >10, >8, >8, >8, or >8 milli Merck units (mMU)/mL respectively). |
baseline and 7 months
|
|
Change in geometric mean titers ratios
Lasso di tempo: baseline and 7 months
|
The geometric mean titers (GMT) ratios will be determined by a post-vaccination geometric mean titer (GMT) ratio with a pre-stated analysis of variance model (95% Confidence Interval lower bound >0.5). |
