Omission of Postoperative Radiation in HPV-Associated Oropharyngeal Cancer Using ctHPVDNA Surveillance (OPERATION)

This single-arm Phase II trial evaluates whether omission of postoperative radiotherapy is feasible and oncologically safe in select patients with HPV-associated oropharyngeal squamous cell carcinoma (HPV-OPSCC). Eligible patients undergo transoral robotic surgery (TORS) and are observed without adjuvant radiation if they demonstrate low or intermediate pathological risk features and have negative circulating tumor HPV DNA (ctHPVDNA) two weeks post-operatively. Patients are followed with standard clinical surveillance combined with serial ctHPVDNA testing (NavDx®) to facilitate early detection of recurrence and prompt salvage therapy as needed.

Long-Term Follow-up Study of Cantharidin (YCANTH [VP-102/TO-208]) in Patients With Common Warts (Verruca Vulgaris)

People who participated in either the COVE-2 or COVE-3 study for common warts, may be eligible to enroll into this Long Term Follow Up (LTFU) study COVE-4. The main question(s) to answer in this LTFU study are: * To assess the safety of YCANTH (also known as VP-102 in the United Sates or TO-208 in Japan) by assessing concomitant medication use, and adverse events (AEs), including expected local skin reactions (LSRs). * To evaluate the efficacy of continued skin application of YCANTH (VP-102/TO-208) when applied to each common wart once every 21 days for a maximum of 4 additional treatments. Participants with eligible common warts present will receive YCANTH (VP-102/TO-208) with an interval of 21 (± 4) days between applications until there is a wart count of zero (ie, completed clearance has been achieved) or a maximum of 4 additional treatments. Participants with complete clearance will attend Observation Visits at intervals of 42 (± 4) days without treatment. Participants who develop a new wart after having a wart count of zero will resume Treatment Visits every 21 (± 4) days for a maximum of 4 additional treatments. All subjects will attend visits until the End-of-Study (EOS) Visit, which is on Day 378 (0/+ 8 days). If participants still have warts present after 4 additional treatments of YCANTH (VP-102/TO-208) the wart(s) will be discontinued from study and participants will be allowed to seek treatment but should be limited to destructive therapy such as cryosurgery and warts cannot be within 10 mm of any warts that receive(d) study drug treatment . The exact interval of Treatment Visits will be determined by evaluation of the treatment site, taking into account any ongoing local skin reactions (LSRs), which are defined as temporary application site: vesiculation, pain, pruritus, scabbing, erythema, discoloration, dryness, edema and erosion that is expected and consistent with historical treatment with YCANTH (VP-102/TO-208). Participants may receive treatment until all treatable common warts are clear, up to a maximum of 4 treatment sessions, or until Day 357, whichever occurs first. Treatment: For participants with warts present at the time of study entry, the first treatment application may occur on the same day as transition from the parent study. All required parent study assessments must be complete, including the final evaluation of response to treatment (ERT; as defined in Assessments and procedures). In addition, eligibility for participation in the LTFU study must have been determined, and informed consent/assent for participation in this LTFU study obtained. YCANTH (VP-102/TO-208) will be applied by the Investigator or qualified member of the research team to treatable common warts, including an approximate 1 to 2 mm margin of healthy, surrounding skin. After YCANTH (VP-102/TO- 208) is applied, warts are to be covered with occlusive tape (occlusive tape with similar properties should be used across all clinical sites) that will remain in place overnight and should be removed 24 hours after application of study drug and just before a 24-hour ERT. Before application of study drug, wart paring, if necessary, will be completed with a sharp surgical instrument (eg, scalpel or flexible medical blade) to remove any adherent thick scale from a treatable common wart. Wart paring is required to be performed at any treatment visit when adherent thick scale is present, and the Investigator feels paring can be safely performed. Paring should be conducted by a trained practitioner and in compliance with any local regulations and should be discontinued if it results in punctate bleeding or significant pain. Not all treatable common warts may require paring. If adherent scale is not present, study drug can be applied without paring. The assessment for complete clearance may be made once all treatable common warts are evaluable and not obscured by an ongoing LSR. If the Investigator is unable to evaluate or treat 1 or more warts due to ongoing LSRs, no warts should be treated, and the visit will be documented as an Unscheduled Visit. The timing of the next treatment visit will be determined by resolution of the LSRs. The research team will be in contact with the Participant until all LSRs are resolved. Once LSRs have resolved, a Treatment Visit will be scheduled within 21 (± 4) days of the previous treatment application, noting it may be longer than 21 (± 4) days depending on the length of time until LSR resolution. All treatable common warts that are not completely clear should undergo treatment with study drug. Study duration from Days 84, 105, or 147 of the parent study (COVE-2 or COVE-3) through the final EOS visit of this LTFU study (Day 378) is approximately 294 days.

Effectiveness of a Vaginal Gel on CIN1/2 Regression and HPV Clearance.

The goal of this clinical trial is to evaluate whether a Coriolus versicolor-based vaginal gel promotes regression of CIN1/CIN2 and facilitates HPV clearance in women aged 30-50 years diagnosed with CIN1 or CIN2 and HPV. In addition, the study will assess patient satisfaction, treatment compliance and characterize the vaginal microbiome. The primary outcomes therefore is: * the regression of the cervical dysplasia from baseline to the follow-up (6 months), which will be assessed through either liquid-based cytology and/or histopathology (biopsy). * HPV clearance from baseline to follow-up (6 months) In this randomized controlled study, eligible participants will be randomized 1:1 into two groups: 1. Intervention group: Women (n=35) will apply a CV-based vaginal gel (Papilocare®) daily for 21 days for 3 months. Afterward, the gel should be used every other day for an additional 3 months. Every month includes a 7-day break due to menstruation (28 days cycle). 2. Control group; Women (n=35) will follow the conventional "wait and see" approach.

Using Plasma Human Papillomavirus (HPV)-Related Deoxyribonucleic Acid (DNA) and Ribonucleic Acid (RNA) to Follow Response of Cervical Cancer to Surgery, Radiation, and Chemotherapy

The goal of this study is to test two commercially available technologies for their ability to detect treatment response in patients with cervical cancer following surgery, radiation, and chemotherapy: one based on polymerase chain reaction (PCR; NavDx) and the other on branched DNA (Quantivirus HPV \[DNA\]). A 9-month feasibility study will be performed to examine the side-by-side utility of both NavDx and Quantivirus HPV DNA assays in predicting cervical cancer treatment response. These tests could prove to be highly sensitive methods for evaluating minimal residual disease and for quantitation of response to surgery, radiation, and chemotherapy in patients with cervical cancer. Primary Goal: Feasibility for NavDx HPV DNA assay (Naveris, Inc) to be used for personalized prediction of tumor response before and after treatment. Secondary Goals: 1. Comparability of the Quantivirus HPV DNA/mRNA assay (DiaCarta, Inc) with the NavDx HPV DNA assay and, 2. Feasibility of the Quantivirus technology for measuring treatment response within the first day to 2 weeks of radiation, surgery, or a new chemotherapy.

Risk Assessment of Community Spread of Multiple Endemic Infectious Diseases in a One Health Perspective

RACSMEI addresses the high burden of infectious diseases in low- and middle-income countries, including Cambodia, where limited surveillance and laboratory capacity often obscure etiologies and transmission dynamics. This knowledge gap hinders the design of effective prevention and control strategies. RACSMEI will improve understanding across multiple pathogens using a multidisciplinary One Health approach. We will answer key questions on burden, ecology, transmission and population immune status to inform targeted and culturally appropriate interventions. The project combines a nationally representative One Health survey, social-science methods, and multiplex, diverse diagnostics to efficiently test for 57 priority pathogens, including zoonotic and vector-borne agents, vaccine-preventable and elimination-targeted diseases, enteric, respiratory, and environmentally transmitted pathogens and selected neglected tropical diseases and parasites relevant to Cambodia. Mathematical modelling will reconstruct and forecast transmission dynamics and assess the potential impact of future public-health strategies. By integrating intersectoral data and innovative methods, RACSMEI will generate actionable evidence for public-health authorities, support precision One Health interventions, and help reduce disease burden in affected communities. The project also aims to ensure the transferability of methods and insights to other countries facing similar challenges.

Cantharidin Application in Patients With Common Warts (Verruca Vulgaris) (COVE-2)

This is a Phase 3, double-blind, randomized, vehicle-controlled study (Study number VP-CW-301; referred to as COVE-2 \[Cantharidin and Occlusion in Verruca Epithelium\]) to evaluate the efficacy and safety of YCANTH (VP-102) treatment in subjects with common warts.

Knowledge and Beliefs of Hearing Impaired Individuals Regarding Human Papillomavirus (HPV)

Health education is one approach to influencing individuals, groups, or communities to achieve better health. The literature indicates that increasing awareness of HPV, along with participation in early screening and vaccination programs, can positively influence attitudes and behaviors. Therefore, this research will be conducted to determine the effect of education using the card game method on the knowledge and health beliefs of hearing-impaired individuals regarding Human Papilloma Virus (HPV).

Transmission of Oncogenic HPV Infection Among Families

The goal of the Transmission of Oncogenic HPV Infection Among Families (TREVINO) study is to improve understanding of how high-risk human papillomavirus (HPV) infections are transmitted within families. The research focuses on transmission between sexual partners and between parents and children. It also examines how the various microbes may influence the persistence of HPV infections and the development of HPV-related cancers. The study will include up to 300 couples recruited from gynecology and ear, nose, and throat (ENT) clinics in Finland, as well as their children. Participants include individuals with persistent HPV infection, cervical precancer or cancer, or HPV-related head and neck cancer, along with their partners and potentially their offspring. Participants will provide self-collected samples from the oral and genital areas at multiple time points over up to five years. Questionnaires addressing medical, behavioural, and environmental factors will be completed. The study is conducted at Tampere University Hospital and Kuopio University Hospital in Finland. Results will inform HPV screening and prevention programs, improve understanding of family-level transmission, and identify potential microbial and genetic markers linked to cancer risk.

Unidos Contra el VPH

The purpose of the Unidos Contra el VPH study is to help find options to screen, or check, for cervical cancer that individuals can do at home to help prevent and detect cervical cancer early. Usually, people get screened for cervical cancer with a Pap smear and human papillomavirus (HPV) test by a health care provider. This is not always easy for individuals who are not able to get to a clinic or feel uncomfortable having the procedure done. That is why we want to find other ways that may be easier and more comfortable for people to be screened for cervical cancer. The two main questions the study aims to answer are: 1. How do the following three cervical cancer screening methods compare for improving screening completion rates? o In-home HPV self-sampling with a vaginal swab * In-home HPV self-sampling with urine testing * In-clinic traditional Pap smear with HPV test 2. What are participant beliefs and preferences regarding these three screening methods? Participants in the study will be randomly assigned to one of three groups. This means each person has an equal chance of being placed in any group. They will also complete two surveys as part of the study. The three screening method groups are described below: Group 1: Urine Self-Sampling * Participants in this group will receive a kit with a urine sample cup to use at home, instructions explaining how to take the sample and a pre-paid mailing box to mail the urine sample to the lab. Group 2: Vaginal Swab Self-Sampling o Participants in this group will receive a kit with a vaginal swab and collection tube to use at home, instructions explaining how to take the sample and a pre-paid mailing box to mail the sample to the lab. Group 3: In-Clinic Screening * An in-clinic co-testing appointment is scheduled for a Pap smear and HPV test done together at Project Vida Health Center. By comparing these approaches, this study aims to improve access to cervical cancer screening and provide better options for those who face barriers to clinic-based screening.
