Einzeldosis-HPV-Impfung zur Prävention von Gebärmutterhalskrebs bei jungen erwachsenen Frauen in Costa Rica, die PRISMA ESCUDDO-Studie (PRISMA)

21. Oktober 2026 aktualisiert von: National Cancer Institute (NCI)

Einzeldosis-HPV-Impfung bei jungen erwachsenen Frauen in Costa Rica: die PRISMA-ESCUDDO-Studie (PRevencIón Del Cáncer Cervical Con Una Sola Dosis de Vacuna Contra VPH en Mujeres Adultas Jóvenes)

This phase IV trial tests whether a single dose of the human papillomavirus (HPV) vaccine works in preventing cervical cancer in young women in Costa Rica. Human papilloma viruses, called HPV, are a group of viruses that very frequently cause infection in both men and women, mainly in the genital organs. There are many types of HPV, and some can cause cancer. The World Health Organization recommends a two-dose schedule for adolescents 9-14 and three doses for individuals 15 years old or older. This study examines whether a single dose of HPV vaccine can reduce the frequency with which women between ages 18-30 become infected with HPV.

Detaillierte Beschreibung

PRIMARY OBJECTIVES:

I. To evaluate one dose of nonavalent human papillomavirus (HPV) vaccination compared to no vaccination in the protection against incident HPV16/18 cervical HPV infections that persist 6-months or more in women aged 18 to 30 years who are cervical HPV16/18 deoxyribonucleic acid (DNA) negative prior to and at the time of vaccination.

II. To evaluate one dose of bivalent HPV vaccination compared to no vaccination in the protection against incident HPV16/18 cervical HPV infections that persist 6-months or more in women aged 18 to 30 years who are cervical HPV16/18 DNA negative prior to and at the time of vaccination.

SECONDARY OBJECTIVES:

I. To quantitate the benefit of one dose of HPV vaccination compared to no vaccination in the protection against incident HPV16/18 cervical HPV infections that persist 6-months or more in women aged 18 to 30 years regardless of cervical HPV DNA status at the time of vaccination (i.e.: vaccine effectiveness in an intention to treat [ITT] analytical cohort).

II. To evaluate one dose of HPV vaccination compared to no vaccination in the protection against cervical infections that persist 6-months or more in women aged 18 to 30 years for the following HPV groupings and individual HPV types (analyzed in an ATP cohort and an ITT cohort):

IIa. Seven carcinogenic types in the nonavalent HPV vaccine: HPV 16/18/31/33/45/52/58 (analyzed both as an aggregate group and individually); IIb. Non-carcinogenic, genital warts-associated types: HPV 6/11 (analyzed both as an aggregate group and individually).

III. To evaluate one dose of HPV vaccination compared to no vaccination in the protection against HPV16/18 anal and oral infections that persist 6-months or more in women aged 18 to 30 years (analyzed in an ATP cohort and an ITT cohort).

IV. To evaluate the immunogenicity (absolute levels, proportion of seropositivity, and stability of serum antibodies) of single dose HPV vaccination in women aged 18 to 30 years. When looking at these antibodies, the primary focus will be on HPV16/18; antibodies against additional HPV types included in the nonavalent HPV vaccine will also be investigated.

ANCILLARY OBJECTIVES:

I. To evaluate one dose of HPV vaccination compared to no vaccination in the protection against HPV cervical, anal or oral infection detected at a single timepoint in women aged 18 to 30 years, including but not limited to the following endpoints:

Ia. HPV16/18; Ib. HPV 16/18/31/33/45/52/58; and Ic. HPV6/11. II. To estimate the health impact of older-age single-dose HPV vaccination by modeling the number of cervical cancer cases prevented as well as the cost-effectiveness of cervical cancer prevention strategies incorporating vaccination and screening in Costa Rica.

OUTLINE: Participants are randomized to 1 of 3 arms.

ARM I: Participants receive one dose of recombinant human papillomavirus nonavalent vaccine (Gardasil 9) intramuscularly (IM).

ARM II: Participants receive one dose of recombinant human papillomavirus bivalent vaccine (Cervarix) IM.

ARM III: Participants receive one dose of diphtheria toxoid/tetanus toxoid/acellular pertussis vaccine adsorbed vaccine (Adacel) IM.

After completion of randomization and vaccination, participants are followed for 36 months. At 6 months they receive a phone contact and, thereafter, they participate in cervicovaginal self-sampling every 6 months, annual serology, and oral/anal sampling at selected visits.
