Filter by:This study is looking to see if nivolumab, an immunotherapy drug, given with carboplatin and paclitaxel (2 chemotherapy agents) during induction therapy in advanced stage HPV negative patients can significantly shrink the subject's cancer.
Recurrent Respiratory Papillomatosis (RRP) causes wart-like growths in the airway which can make it difficult to breathe, speak and carry out normal everyday activities. It is a rare condition affecting all ages, but is more common and aggressive in children than in adults, affecting 4 in every 100,000 children. There is no known cure for RRP, but symptoms are checked through regular hospital visits, with multiple therapies or procedures under general anaesthetic needed to remove or shrink the growths which can grow back quickly. The problem is that nobody knows which therapies or procedures work best. Aim: To identify which RRP treatments currently used in National Health Service (NHS) hospitals within the United Kingdom (UK) are the most effective and safest in the short- and long-term. It will also identify which patients respond best to specific treatments, and those who are at higher risk of experiencing a complication after treatment. Method: Collect information from usual patient care and quality of life questionnaire responses in a secure online database. Participation in this study requires patient/parent/guardian consent. This observational study does not require patients to undergo any additional intervention as part of the research.
The purpose of this clinical trial is to evaluate the safety and efficacy of IV-infused autologous or allogenic HPV-CTLs.
The purpose of this research is to assess the safety and effectiveness of circumferential radiofrequency ablation (RFA) to the anal canal using the BarrxTM Ablation System to destroy anal high-grade squamous intraepithelial lesions (HSIL). The BarrxTM Ablation System used in this study comprises an RFA generator (Barrx™ FLEX) and the BarrxTM Anorectal Wand. The generator and wand are cleared by the Food and Drug Administration (FDA) for human use and the wand is specifically cleared for treatment of anal intraepithelial neoplasia (AIN). AIN is a precancerous condition. HSIL is an advanced form of AIN. The presence of HSIL has traditionally warranted treatment. RFA has been shown in many studies to effectively and safely destroy precancerous cells in a condition called Barrett's esophagus, which is a precancerous condition of the esophagus (the swallowing tube). Recent studies have shown that RFA may offer the same benefits for those with HSIL in the anal canal. In particular, ablation of the entire circumference of the canal seems to reduce recurrence of HSIL in other locations of the anal canal. This study will last between 12 to 15 months. Subjects will be required to undergo 5 to 8 study visits as outlined below that are carried out by the study doctors or the physician assistant. Most visits will last approximately one hour. Some may be shorter and some may be longer. Up to seventy (70) volunteers will participate in this study at several locations.
In the genital tract human papilloma virus (HPV), especially types 6 and 11 cause genital warts, the commonest viral sexually transmitted disease. The HPV 16 and 18 are the most common oncogenic "high-risk" genotypes and cause approximately 70% of all cervical cancers despite the fact that are associated with other anogenital cancers, anus, vagina, vulva and penis, and cancers of the head and neck. Current estimates are that 5.2% of all cancers are HPV associated. A large number of studies, including both adult and young females, have demonstrated that HPV vaccines are highly immunogenic and induce a long lasting protection against infection. Immunogenic vaccination results in young men and boys are equally satisfactory with the quadrivalent HPV (types 6, 11, 16, 18) vaccine recommended for men. The recommended vaccination scheme includes three shots giving the second at two months and the third at six months after the initial shot. Recently, it has been shown that the use of a two shot scheme (0 and 6 months) is equally effective among girls. The purpose of this study is to determine that the immunogenicity is non-inferior in boys using a two shot scheme compared with young women and girls.
The investigators have planned this project to evaluate the follow-up program after surgery due to cervical cancer and to explore the possibilities for different tests of Human Papilloma Virus (HPV) in contributing to the customization of the follow-up program. Purpose: The investigators effort is to provide the background for an evidence-based update of the follow-up program after surgery due to cervical cancer with the purpose of early diagnosis of recurrence affecting quality of life for as few women as possible.
The purpose of the study is to evaluate the effectiveness of a managed care-based HPV vaccination reminder/recall system using a randomized controlled trial (RCT) across diverse practices and patient populations. The trial will measure the effectiveness of text messaging reminder/recall on (a) improving initiation and (b) completion rate of the HPV vaccine series; (c) decreasing the time between vaccine doses; and (d) improving rates of preventive visits for adolescents The hypotheses are that text-messaged reminders to parents of adolescents will result in improved rates of HPV vaccine series initiation, HPV vaccine series completion, will decrease the intervals between vaccine doses and will improve rates of preventive care among adolescents. Parents receiving specific text-messaged reminders about services (i.e. HPV vaccination, well child care visits) for which their adolescent is due will be compared to a control group of parents receiving general health tips through text messages.
Human papilloma virus (HPV) infection contributes as a main causative factor to the development of invasive cervical cancer (ICC) and its precursors (cervical intraepithelial neoplasia, CIN). Currently, two prophylactic vaccines are employed for the prevention of genital HPV infection. As the prophylactic efficacy is type-restricted, determining the type-specific HPV distribution and their associations with ICC and its precursors would provide essential information in assessment of HPV vaccination program impact. The baseline information is also important for monitoring possible changes in type-specific HPV distribution after vaccination has been introduced. Prevalence of HPV infection varies considerably across the world, and data were limited from less-developed countries. Knowledge of the detail pattern of HPV type-specific distribution in each region will be essential for public health policy decisions. This will also form the basis for determining which types should be included in future generation HPV vaccines targeted to specific regions. While most studies were focus on ICC and high-grade cervical lesions, the association between HPV types and the progression of CIN1 has rarely been studied. CIN1 is an insensitive histopathological sign of HPV infection, most of which will spontaneously regress to normal with host immune system. However, some genotypes have been described as being more persistent and associated with progression from low-grade lesions to high-grade lesions, even ICC. Geographical data on type-specific prevalence of HPV in CIN1 with appropriately designed prospective studies would be helpful in identifying types preferentially associated with progression to malignancy and accurately predicting the future impact of vaccination in specific regions. Free vaccination supported by the government appears to be unlikely at present in China. Thus, individuals need to pay the cost of vaccines for themselves presently. Yangtze River Delta Area is the most economically developed regions in China, and people here may become the largest vaccinated population at their own expense in China. To the best of the investigators knowledge, no multi-center study on HPV type-specific distribution and their associations with ICC and its precursors is available in Yangtze River Delta Area, China, which highlights the need for timely study in this region before large scale vaccination programs are carried out.
