Active clinical trials for "Anus Neoplasms"

This study is designed to evaluate the immunogenicity and tolerability of 9vHPV (9-valent HPV vaccine, V503) in 16- to 26-year old men and women. The overall goal is to bridge 9vHPV efficacy findings in young women to young men based on the demonstration of similar immunogenicity and safety profiles. The primary hypothesis is that 9vHPV induces antibody responses at 4 weeks postdose 3 in heterosexual males that are non-inferior to antibody responses in young women.

Phase I/II trial to study the effectiveness of SGN-00101 in preventing anal cancer in HIV-positive patients who have high-grade anal neoplasia. Chemoprevention therapy is the use of certain drugs to try to prevent the development of cancer. SGN-00101 may be effective in preventing anal cancer.

The goal of this project is to test the efficacy of a chatbot intervention for reducing HPV vaccine hesitancy among African American parents. An online experiment will be conducted to test the effectiveness of the chatbot intervention with African American parents. Results of this project will inform future communication interventions for reducing vaccine hesitancy among African American parents.

RATIONALE: Vaccines made from a gene-modified virus may help the body build an effective immune response to prevent viral infection. PURPOSE: This phase II trial is studying how well vaccine therapy works in preventing human papillomavirus (HPV) infection in young HIV-positive male patients who have sex with males.

This clinical trial studies anal human papillomavirus (HPV) tests in screening for cell changes in the anus in patients with human immunodeficiency virus (HIV). Screening tests may help doctors find cancer cells early and plan better treatment for anal cancer. Completing multiple screening tests may help find the best method for detecting cell changes in the anus.

RATIONALE: Infrared coagulator ablation may be effective in preventing the development of anal cancer in patients with anal neoplasia PURPOSE: This randomized phase III trial is studying infrared coagulator ablation to see how well it works compared to observation in preventing anal cancer in HIV-positive patients with anal neoplasia.

RATIONALE: Doctors use a swab to collect cell samples when testing for anal cancer and human papillomavirus. It is not yet known which type of swab is more effective in collecting cell samples for anal Pap tests and human papillomavirus tests in men who have sex with men. PURPOSE: This clinical trial is comparing two types of swabs in collecting cell samples for anal Pap tests and human papillomavirus tests in men who have sex with men.

There is no standard screening protocol for anal cancer even as disease incidence increases. This single-visit study will clarify if single persons can do a self-digital anal exam, or perhaps the exam requires a partner, or if, in fact, the exam requires a clinician for reasons of safety, accuracy, or acceptability. The investigators hypothesize that men having sex with men's digital anal exam (DAE) findings will have moderate or substantial agreement with a nurse practitioner DAE for detecting an anal abnormality (defined as condylomas, hemorrhoids, fissures, and malignant tumors). As a secondary hypothesis the investigator believe a partner-assisted DAE conducted within a couple will have better agreement with the nurse practitioner DAE than will a self-DAE conducted by a single person.

The aim of this study is to improve the understanding for the tumour biology in relation to treatment response in patients with anal cancer by examining: The tumour microenvironment The localisation of and cellular interactions between the tumour and immune cells The gene and protein expression by cells present in the tumour and surrounding tissue.

The primary objective of this study, sponsored by Travera in Massachusetts, is to validate whether the mass response biomarker has potential to predict response of patients to specific therapies or therapeutic combinations using isolated tumor cells from varying cancers and biopsy formats.
