A Clinical Trial to Evaluate the Immunogenicity of the Nonavalent Vaccine Against Human Papillomavirus in Men Infected by HIV Who Have Sex With Men. GESIDA 10017

Phase 4
Completed
Conditions
HIV Infections
Interventions
Biological: HPV9v
Registration Number
NCT03626467
Lead Sponsor
Fundacion SEIMC-GESIDA
Brief Summary

Phase IV, open, multicenter and single-arm clinical trial designed to evaluate the immunogenicity of the HPV9v vaccine in men with HIV infection (HIV +) who have sex with men (MSM)

Detailed Description

The investigators estimate that 166 participants will need to be included in the study to evaluate the immunogenicity of vaccine against human papillomavirus in men with HIV infection who have sex with men, by evaluating in two age groups and the seroconversion rate for each of the HPV genotypes included in the vaccine from baseline to month 7 and 24.

Primary Outcome Measures
NameTimeMethod
Percentage of subjects who serocovertize for each of the HPV genotypes included in the vaccineFrom basal until week 96

The HPV genotypes studied are: 6/11/16/18/31/33/45/52/58. The cut-off points to determine serological status 30, 16, 20, 24, 10, 8, 8, 8, and 8 units / mL for HPV genotypes 6, 11, 16, 18, 31, 33, 45, 52 , and 58, respectively

Secondary Outcome Measures
NameTimeMethod
The proportion of subjects with an adverse experience leading to disruptionFrom basal until week 96

Adverse events

The proportion of subjects experiencing adverse eventsFrom basal until week 96

Adverse events

The proportion of subjects with an adverse experience related to medicationFrom basal until week 96

Adverse events

Number of participants with low CD4 / CD8 ratio (<0.5) and normal ratio (> 1)From basal until week 96

The low CD4 / CD8 ratio has been associated with immunosenescence in the serological response, such as worse immunogenicity and worse response to vaccines

Percentage of participants <26 years and ≥ 26 years with persistent anal infection due to HPVBasal, week 28 and week 96
The proportion of subjects with a severe adverse experienceFrom basal until week 96

Adverse events

Number and type of metabolites derived from the microbiota of patientsFrom basal until week 96

Detect biomarkers derived from microbiota and their relationship with the vaccine response

The proportion of subjects experiencing adverse events related to laboratory values at any time during the study periodFrom basal until week 96
