5 Clinical Trials for Various Conditions
This phase IV trial studies how well human papillomavirus (HPV) vaccine therapy works in interrupting progression in patients with high-grade vulvar or anal lesions. Vaccines made from HPV peptides or antigens may help the body build an effective immune response to kill tumor cells and decrease the chance of vulvar or anal lesions to progress or come back.
This trial develops a health-related symptom index for participants with and either treated or monitored for anal high-grade squamous intraepithelial lesions. The health-related quality of life index may help to capture the symptoms and related experiences of living with or being treated for high-grade squamous intraepithelial lesions.
This research trial studies health-related symptom questionnaires in measuring quality of life in human immunodeficiency virus (HIV)-infected participants treated with or monitored for anal lesions. Collecting information and symptoms from patients diagnosed with anal lesions may help reduce the risk of anal cancer.
Assess the safety, feasibility, and patient tolerability of circumferential radiofrequency ablation (RFA) to the anal canal for patients with anal intraepithelial neoplasia (AIN). Patients will have AIN with high grade squamous intraepithelial lesions (HSIL) and the RFA will be applied using the Barrx™ Ablation System.
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.
