Immunogenicity of the 9-Valent Human Papillomavirus Recombinant Vaccine in People With Idiopathic CD4 T Cell Lymphocytopenia : A Phase 2, Open-Label Study to Assess the Immunogenicity of the 9-Valent Human Papillomavirus Recombinant Vaccine in Patients With Idiopathic CD4 T Cell Lymphocytopenia

As observed in other immunocompromised individuals with selective or combined T cell deficits, the prevalence and morbidity of human papillomavirus (HPV)-related disease is increased in patients with idiopathic CD4 T cell lymphocytopenia (ICL). The high burden and aggressive clinical course of HPV-associated disease in patients with ICL requires the development of effective preventive measures in this specific population. The protection from a broader range of HPV types offered by the 9-valent vaccine is expected to be particularly beneficial in this population. This applies even to patients with a history of type-specific HPV-associated disease, as this population may remain at a higher risk of acquisition of infection with new oncogenic HPV types even with increasing age. However, the immunogenicity of vaccines and in particular HPV preventive vaccines has never been systematically studied in patients with ICL.This will be a phase 2, open-label study to assess the immunogenicity of the U.S. Food and Drug Administration (FDA)-approved 9-valent HPV recombinant vaccine GARDASIL 9 in patients 18- through 70-years-old with ICL, irrespective of HPV serostatus, presence of HPV-associated diseases, or previous immunization with bivalent or quadrivalent HPV vaccine, as well as healthy controls matched to the ICL patient group for age and gender. The study will take place at a single site (National Institutes of Health Clinical Center, Bethesda, MD). Participants will be assessed at baseline for history and/or clinical evidence of HPV-associated disease. Those with a history of or current HPV skin or mucosal disease will undergo clinically indicated evaluation and be referred for clinical care as needed. We will administer the vaccine in a population of ICL patients ranging in age from 18 through 70 years old according to the standard 3-dose schedule approved by the FDA for individuals 9 through 45 years of age, with the second and third doses administered at least 2 months and at least 6 months, respectively, after the first dose. Follow-up visits will occur 1 and 18 months after completion of the vaccination schedule. Blood will be collected at each study visit for safety and immunogenicity testing..
