28 Clinical Trials for Various Conditions
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.
This open label study investigates a novel non-surgical approach to the treatment of HPV-associated anal intraepithelial neoplasia, using Artesunate suppositories.
This clinical trial compares three anal cytology collection procedures (collected at a single visit) in men who have sex with men (MSM). It also compares two different tests for human papilloma virus, the virus that causes high grade anal dysplasia, which is thought to occur before anal cancer. This study may help doctors develop better screening for high-grade anal dysplasia in MSM in order to identify those who need to return for additional screening and treatment.
This study is being done to assess the safety of lopinavir/ritonavir in patients with PLWH with AIN. 30 participants will be recruited and can expect to be on active study for approximately 3 months and long term follow up for 40 weeks.
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.
This is a Single-center prospective pilot trial involving up to 22 subjects. This study will assess the feasibility, safety, and efficacy of radiofrequency ablation (RFA) to the anal canal using the FDA cleared HALO Ablation System to eradicate anal HSIL lesions in HIV-negative subjects with intra-anal intraepithelial neoplasia (AIN). The study intervention will demonstrate that a reasonable proportion of subjects will be histologically cleared of their anal HSIL within the ETZ in a tolerable and relatively safe manner
This phase II trial studies the use of human papillomavirus (HPV) deoxyribonucleic acid (DNA) plasmids therapeutic vaccine VGX-3100 (VGX-3100) and electroporation in treating patients with human immunodeficiency virus (HIV)-positive high-grade anal lesions. Vaccines made from DNA may help the body build an effective immune response to kill tumor cells. Electroporation helps pores in your body's cells take in the drug to strengthen your immune system's response. Giving VGX-3100 and electroporation together may work better in treating patients with high-grade anal lesions.
This is a phase 2, open-label efficacy study of VGX-3100 administered by intramuscular (IM) injection followed by electroporation (EP) in adult men and women who are human immunodeficiency virus (HIV) negative with histologically confirmed anal or anal/peri-anal high-grade squamous intraepithelial lesion (HSIL) associated with human papilloma virus (HPV)-16 and/or HPV-18. Approximately 24 participants will receive at least 3 doses of VGX-3100.
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.
This trial studies the prevalence of anal dysplasia and anal cancer in patients with cervical, vaginal, and vulvar dysplasia and cancer. Studying samples collected from patients in the laboratory may help doctors learn more about the human papillomavirus and how often anal cancer occurs in patients with cervix, vagina, or vulvar cancer.
This randomized phase III trial studies imiquimod or fluorouracil to see how well they work compared to observation in treating patients with high-grade anal squamous skin lesions who are human immunodeficiency virus (HIV)-positive. Biological therapies, such as imiquimod, may stimulate the immune system in different ways and stop tumor cells from growing. Drugs used in chemotherapy, such as fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether imiquimod or fluorouracil is more effective than observation in treating high-grade anal squamous skin lesions.
This is a phase II double blind, placebo-controlled, randomized study of Artesunate suppositories for the treatment of HIV-negative men and women who have anal high grade squamous intraepithelial lesions (anal HSIL)
The goal of this study is to test the maximum tolerated dose of ACU-D1 in HIV-positive people with HPV-associated vulvar and perianal lesions. The main questions it aims to answer are: * The maximum tolerated dose of ACU-D1 * Safety and tolerability of topical ACU-D1 * Whether topical ACU-D1 induces p53 and p53-mediated downstream signaling (including p21 induction) in HPV-related lesions * Whether topical ACU-D1 enhances markers of immunity in HPV-infected HIV-positive individuals Participants will be asked * To apply ACU-D1 on the lesions twice daily for 4 weeks * 3 biopsies will be performed at the screening and 3 at the end of 4 weeks.
The goal of this single arm trial is to prospectively evaluate screening methods for anal cancer precursors in HIV uninfected women with a history of lower genital tract neoplasias and cancers.
The purpose of this study is to finalize development of a questionnaire that measures health-related symptoms and concerns for persons diagnosed with, and either treated or monitored for, anal pre-cancer lesions.
The purpose of this study is to find out if a Chinese herbal cream is effective in treating HSIL (high-grade squamous intraepithelial lesions, also known as HGAIN, or high-grade anal intraepithelial neoplasia).
The purpose of this study is to see if curcumin can reverse anal high-grade squamous intraepithelial lesions (aHSIL) (high-grade anal precancerous cells or high-grade abnormal cells) in people living with HIV to avoid current treatments such as ablation (destroying abnormal cells with heat or surgical excision (cutting out the abnormal cells)), which have potential short- and long-term side effects.
Background: Human papillomavirus (HPV) can cause cervical, throat, anal, and genital cancers. Cancers caused by HPV have a HPV protein called E7 inside of their cells. In this new therapy, researchers take a person s blood, remove certain white blood cells, and insert genes that make them to target cancer cells that have the E7 protein. The genetically changed cells, called E7 TCR cells, are then given back to the person to fight the cancer. Researchers want to see if this can help people. Objective: To determine a safe dose and efficacy of E7 TCR cells and whether these cells can help patients. Eligibility: Adults ages 18 and older with an HPV-16-associated cancer, including cervical, vulvar, vaginal, penile, anal, or oropharyngeal. Design: Participants will list all their medicines. Participants will have many screening tests, including imaging procedures, heart and lung tests, and lab tests. They will have a large catheter inserted into a vein. Participants will have leukapheresis. Blood will be removed through a needle in the arm. A machine separates the white blood cells. The rest of the blood is returned through a needle in the other arm. The cells will be changed in the lab. Participants will stay in the hospital. Over several days, they will get: Chemotherapy drugs E7 TCR cells Shots or injections to stimulate the cells Participants will be monitored in the hospital up to 12 days. They will get support medicine and have blood and lab tests. Participants will have a clinic visit about 40 days after cell infusion. They will have a physical exam, blood work, scans, and maybe x-rays. Participants will have many follow-up visits with the same procedures. At some visits, they may undergo leukapheresis. Participants will be followed for 15 years.
The randomized phase of the trial compared topical or ablative treatment with active monitoring in preventing anal cancer in patients with human immunodeficiency virus (HIV) and high-grade squamous intraepithelial lesions (HSIL). Anal HSIL is tissue in the anal canal that has been damaged by infection with human papillomavirus (HPV) and is at risk for turning into anal cancer. The ANCHOR Data Safety Monitoring Board (DSMB) determined that the primary study endpoint was completed, based on the data and statistical analysis presented to them on 07SEP2021. In the post-randomization phase of this trial, all enrolled participants are offered treatment for HSIL and/or follow-up, at the participant's choice.
This study evaluates the use of ABI-1968, a topical cream, in the treatment of anal precancerous lesions in adults with and without human immunodeficiency virus (HIV) infection
This study evaluates the use of ABI-1968, a topical cream, in the treatment of anal precancerous lesions in adults with and without human immunodeficiency virus (HIV) infection.
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: Diagnostic procedures, such as anal swab collection, digital rectal examination, and anal endoscopy and biopsy, may help find and diagnose anal and genital human papillomavirus infection and squamous intraepithelial lesions and help doctors plan better treatment. PURPOSE: This clinical trial is studying ways to detect anal and genital human papillomavirus infection and squamous intraepithelial lesions in HIV-positive patients enrolled in an AIDS cancer clinical trial.
RATIONALE: High-grade squamous intraepithelial lesions of the skin near the anus are caused by the human papillomavirus (HPV). Antiviral drugs,, such as cidofovir, act against viruses and may stop these lesions from becoming cancer. PURPOSE: This phase II trial is studying the side effects and how well topical cidofovir works in treating HIV-infected patients with high-grade squamous intraepithelial lesions of the skin near the anus.
This study is designed to identify barriers that prevent men who have sex with men from receiving doctor-recommended annual follow-up screenings for anal cancer. Men who are at the highest risk for developing anal cancer will be asked to complete a brief questionnaire (either via telephone or in writing). The questionnaire is designed to identify potential barriers to care-seeking behavior including, relationship status, financial constraints, highest level of education and knowledge about anal cancer and its precursors. The men who agree to participate in the study will then be organized into groups based on their history of coming in for follow-up screening visits after learning that they are at higher risk for developing anal cancer. These groups include 1) men that have come in for regular screening visits (at least once per year), 2) men who came in once and were then lost to follow-up, 3) men who came in for more than one screening visit and were then lost to follow-up, and 4) men who were previously lost to follow-up and then began coming in for screening again. By comparing the men's responses across the different groups, we hope to uncover key barriers and drivers to follow-up screenings for anal cancer. The goal of this study is to evaluate the differences in questionnaire responses across cohorts that may impact care-seeking behavior. We hypothesize that: * Patients who regularly comply with annual follow-up screening visits score higher on questions assessing knowledge of HPV and anal cancer. * Men in stable relationships are more likely to comply with annual screening visit recommendations. * Men who are educated by their primary care physicians about the importance of anal cancer screenings have higher screening rates.
RATIONALE: Infrared coagulation may be effective in preventing the development of anal cancer in patients who have anal neoplasia. PURPOSE: Pilot study to evaluate the effectiveness of infrared coagulation in preventing anal cancer in HIV-positive patients who have high-grade anal neoplasia.
