Brief summary

Patients with immunodeficiencies are at increased risk of developing persistent HPV infection and as such HPV-related disease (genital warts and cancer). In this study HIV-patients and SOT-patients will receive 3 doses of Gardasil®9. Safety, tolerability and immunogenicity will be evaluated up to one month following the 3rd and last dose of Gardasil®9.

Detailed description

This is a single-center, open-label study on safety, tolerability and immunogenicity of Gardasil®9 in 18 to 45 year-old HIV patients, in 18 to 55 year-old solid-organ transplant (SOT) patients. This study will enrol 140 HIV patients with CD4+ (cluster of differentiation 4) count of \>200cells/mm² and 170 SOT patients, all of whom have not yet received a prophylactic HPV vaccine. The 170 SOT patients will be equally divided over 3 different SOT patient groups, namely heart, lung and kidney transplant patients. Therefore the target is to include approximately 57 heart transplant patients, 57 lung transplant patients and 57 kidney transplant patients. Enrolment in a SOT subgroup will be stopped when 57 patients have been included unless recruitment cannot be achieved within one of the other SOT-patient population. All enrolled subjects will receive a 3-dose regimen (Day 1, Month 2, and Month 6) of GARDASIL®9. Serum samples will be collected on Day 1 and Month 7 for anti-HPV 6, 11, 16, 18, 31, 33, 45, 52, and 58 antibody determination.. The time point for comparison of immune responses will be Month 7, or approximately 4 weeks after the administration of the third dose. The safety/tolerability profile of the vaccine will be evaluated in all subjects in the study. Safety information will be collected on Day 1 through 1 month following the third vaccination or for a total of approximately 7 months for each subject. The immunogenicity and the safety data will be analyzed per group of patients. More specifically a separate analysis of HIV and SOT patients is planned, since it is expected that the immunosuppressive therapy of SOT patients might have a more profound effect on immunogenicity following vaccination. This study will provide a comparison of immunogenicity of Gardasil ®9 in immunocompromised patients, with historical controls (15, 18). The number of subjects to be enrolled in the study was determined based on the primary immunogenicity objective.

Inclusion criteria

1. Independent Ethics Committee (IEC)-approved written informed consent form (ICF) must be obtained from the subject prior to any study-related procedures (including discontinuation of prohibited medication, if applicable) by the subject is given as required by local law. 2. Subject (man or woman) is between the age of 18 years and 0 days and 45 years and 365 days for HIV patients, between 18 years and 0 days and 55 years and 365 days for transplant patients at time of signing the ICF 3. Subject is able to understand and adhere to the study procedures (e.g., is not planning to relocate far from the investigational centre during the study period); is able to read, understand, and complete the vaccination diary; is able to understand the risks involved with the study; and voluntarily agrees to participate in the study by giving written informed consent. 4. \* Since the first day of their last menstrual period through Day 1, female subjects have not had sex with males or has had sex with males and used effective contraception with no failures (an example of a failure is a male condom that ruptures during sexual intercourse). Effective contraception is defined as a marketed, approved contraceptive product that the subject has used per the manufacturer's instructions with every act of sexual intercourse. The subject understands and agrees that during the Day 1 through Month 7 period, she should not have sexual intercourse with males without effective contraception. The use of the rhythm method alone, withdrawal alone, and emergency contraception, are not acceptable methods per the protocol. Subjects who have reached menopause, undergone hysterectomy, bilateral oophorectomy, or bilateral tubal ligation are eligible without the use of contraceptives. Postmenopausal status is defined as: (1) No menses for \>1 year but \<3 years and confirmed by follicle stimulating hormone (FSH) levels elevated into the postmenopausal range, or (2) no menses for at least 3 years. 5. \* Subject has had no temperature ≥37.8°C within 24 hours prior to the first injection. 6. Patient considerations * HIV patients: have CD4+ T cell count of \>200 cells/mm² at the last control (less than 12 months ago). * SOT patients received their organ transplantation ≥12 months prior to vaccination and has been stable in the past 6 months (i.e. no acute rejection or other immunological reactions). 7. Apart from having HIV or received a solid organ transplant, the subject is in stable condition (i.e. no graft-versus-host disease or other immunological reactions) and is judged to be in good physical health on the basis of medical history, physical examination (if deemed necessary), and laboratory testing 8. Subject agrees to provide study personnel with a primary telephone number as well as an alternate telephone number for follow-up purposes.

Exclusion criteria

1. Subject has a history of an abnormal Pap test or abnormal cervical biopsy results (showing cervical intraepithelial neoplasia or worse) or cervical disease (i.e., surgical treatment for cervical lesions). 2. Subject has history of genital warts, Vulvar Intraepithelial Neoplasia or Vaginal Intraepithelial Neoplasia. 3. Subject has a history of a positive test for HPV. 4. Subject has a history of known prior vaccination with an HPV vaccine, i.e., received a marketed HPV vaccine, or has participated in an HPV vaccine clinical study and has received either active agent or placebo. 5. Subject is pregnant (as determined by serum or urine pregnancy test). 6. Subject is, at the time of signing ICF, a user of recreational or illicit drugs or has had a recent history (within the last year) of drug or alcohol abuse or dependence. Alcohol abusers are defined as those who drink despite recurrent social, interpersonal, and/or legal problems as a result of alcohol use. 7. Subject has a history of severe allergic reaction, including known allergy to any vaccine component, including aluminum, yeast, or BENZONASE® (nuclease, Nycomed \[used to remove residual nucleic acids from this and other vaccines\]) (e.g., swelling of the mouth and throat, difficulty breathing, hypotension or shock) that met the criteria for serious adverse experiences defined in this protocol. 8.

Exclusion criterion only for HIV patients: Subject has had a splenectomy, or has been diagnosed as having a congenital immunodeficiency, lymphoma, leukaemia, systemic lupus erythematosus, rheumatoid arthritis, juvenile rheumatoid arthritis, inflammatory bowel disease, or other autoimmune or immunosuppressive condition, or has a history of any disease, which, in the investigator's opinion, may confound the results of the study or pose an additional risk to the subject. 2. Exclusion criterion only for SOT patients: Subject has had a splenectomy, or has been diagnosed as having a congenital or acquired immunodeficiency, HIV infection, lymphoma, leukaemia, systemic lupus erythematosus, rheumatoid arthritis, juvenile rheumatoid arthritis, inflammatory bowel disease, or other autoimmune or immunosuppressive condition, or has a history of any disease, which, in the investigator's opinion, may confound the results of the study or pose an additional risk to the subject. 9.
