Filter by:We are evaluating whether 15-26 year old males and females need a 3rd dose of the human papillomavirus (HPV) vaccine, or whether 2 doses provide similar protection as 3 doses from the 9 types of HPV that it protects against.
In sinonasal inverted papilloma (SNIP) it is very challenging to discriminate between tumor and surrounding tissue. Local recurrence is a frequent phenomenon as it occurs in 16.5% of the cases. There is need for an instrument that is able to guide the surgeon in removing all tumor tissue, whereas resection of healthy tissue is minimalized. Molecular fluorescence guided surgery enables the visualization of targeted tumor-specific biomarkers by using fluorescence, thereby enhancing the contrast between normal mucosa and tumor tissue. The objective of this feasibility study is to determine if the intravenously administered conjugate bevacizumab-IRDye800CW accumulates more in SNIP than in normal sinonasal epithelium.
This is a single-arm Phase II study of adjuvant radiation for locally advanced p16+ oropharyngeal squamous cell carcinoma. The main purpose of this research is to determine the likelihood of cancer growing back in the throat or in the neck two years after completion of radiation if lower doses of radiation are used to a smaller area of the head and neck region than is currently used in standard of care.
This study will screen people for oncogenic oral Human Papillomavirus (HPV) infection and antibodies to form a cohort of people who may be at increased risk of HPV-oropharyngeal cancer (HPV-OPC). The investigators will follow these individuals prospectively to evaluate oncogenic oral HPV persistence, risk factors, and biomarkers for persistence.
The goal of this study is to engage rural primary care clinics and community organizations to test interventions designed to increase HPV vaccinations in both male and female patients aged 9-26 years.
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 100 HIV patients with CD4+ 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. The number of subjects to be enrolled in the study was determined based on the primary immunogenicity objective.
To investigate the treatment related effects of transoral robotic surgery (TORS) or oncological treatment of oropharyngeal squamous cell carcinoma with a 1-year follow up.
Phase IV prospective study measuring the immunogenicity (neutralizing antibody titles against each HPV vaccine genotype) of the 9-valent vaccine against HPV (Gardasil9®Merck) in HIV-positive women aged 15-40 years with fully suppressed HIV viremia on combined antiretroviral therapy. After a first open phase evaluating tolerability of Gardasil9 (from June 2018 to December 2018), an amendment was introduced to randomize women between two different doses schedules: in the first schedule (ARM A), women will receive 2 doses at time 0 and 6 months and a third dose between 18-48 months if their antibody levels are insufficient; the second schedule (ARM B) will be 3 doses at 0, 2 and 6 months. Primary outcome is the non-inferiority of the rate of seroconversion against each HPV vaccine genotypes in women seronegative at baseline after either 2 or 3 doses of vaccination (month 7). Secondary outcomes are rate of seroconversion after 3 doses if they have received a third dose, completion of vaccine schedule, vaccine safety, antibody titles, and induction of cellular immunity against HPV contained in the vaccine, incidence of cervical HPV infection and incidence of abnormal cytology after vaccination. The safety of the vaccination (local or systemic reaction and impact on HIV viral control and immunodeficiency level) will be assessed. The cellular immune response will be assessed in a subgroup of patients.
Cervical cancer is the most common cancer in women aged 15-44 years in East Africa, and mortality rates are very high. HPV vaccines are most effective if given to girls who have not yet acquired HPV infection. In Tanzania, HPV vaccine has been shown to be safe, acceptable and can be delivered with high coverage (~80%). However, the cost of delivering HPV vaccine is considerably higher than costs for traditional infant/child vaccinations. This is primarily because of costs to establish outreach programmes and associated personnel costs including nurses who must spend significant time away from their posts to deliver vaccine, especially if multiple doses are needed. There is global interest in simplifying HPV vaccine delivery by reducing the number of doses. If a single dose could be given, this could halve the costs of delivery, making it more accessible to the populations that need it most. Recently, the WHO recommended that 2 doses of HPV vaccine could be given to young girls, based on studies in high and upper middle-income countries. However in Africa high rates of infections like malaria and worms can affect immune responses to vaccines. It is essential to know that reducing the number of doses does not reduce the protective immune response of these vaccines. The investigators are conducting a trial in Tanzanian girls aged 9-14 years to establish whether a single dose of HPV vaccine produces immune responses that are likely to be effective in preventing cervical cancer. Two different HPV vaccines, the bivalent (2-v) vaccine that protects against HPV 16/18 (the cause of 70% of cancers) and the 9-valent (9-v) vaccine that protects against 9 HPV types, will be compared. The trial will randomise 900 girls to 6 arms and follow them for 36 months. Girls will receive the 2-v or the 9-v HPV vaccine, as 1, 2 or 3 doses. Girls receiving 1 or 2 doses will be compared with those receiving 3 doses of the same vaccine, to ensure that the reduced dose regimen produces an immune response that is not inferior to 3 doses. Girls in the 1 and 2 dose arms will be enrolled in an extension and followed for up to 9 years, to examine the stability of immune responses. The immune responses in this study will also be compared with results from other countries where the vaccine has been shown to be protective. This will provide information about whether a reduced number of doses is likely to be protective in Africa. This work will be extremely important in informing future HPV vaccination strategies and will be one of the first randomised trials of 1 and 2 doses of any HPV vaccine in Africa.
This research study is evaluating an immune modulatory agent as a possible treatment for patients with Recurrent Respiratory Papillomatosis (RRP) with significant disease involving the larynx, trachea, and/or lungs. The investigators will be using Pembrolizumab as the treating agent.
