A Study of ABI-2280 Vaginal Tablet in Participants With Cervical Intraepithelial Neoplasia
Cervical Intraepithelial NeoplasiaThis is an open-label study to evaluate the safety, tolerability, and efficacy of ABI-2280 in participants with cervical squamous intraepithelial lesions. This study is divided into 2 parts - Part A and Part B. Part A consists of 3 dose escalating cohorts. Part B is a dose expansion cohort. Participants will self-administer ABI-2280.
5-fluorouracil Following Cervical Intraepithelial Neoplasia Treatment Among HIV-positive Women in...
CIN 2/3HIV InfectionsThis is a single arm study on the safety, feasibility, and acceptability of adjuvant, self-administered, intravaginal 5-Fluorouracil (5-FU) following treatment for high-grade cervical precancer (CIN2/3) among women living with human immunodeficiency virus (HIV).
Pembrolizumab for the Treatment of Cervical Intraepithelial Neoplasia
Cervical Intraepithelial NeoplasiaCervical Squamous Cell Carcinoma In Situ1 moreThis phase II trial studies the effect of pembrolizumab on cervical intraepithelial neoplasia. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
Comparison of Cervical CIN II/III Treatment Outcomes With Thermal Ablation Device
Cervical Intraepithelial NeoplasiaThe purpose of this academic-industrial partnership will be to compare two thermoablation modalities using devices adapted to low and middle income countries (LMICs) to traditional CO2-based cryotherapy for the treatment of cervical precancer. The investigators will investigate whether the cure rates of cervical intraepithelial neoplasia 2 and more severe diagnoses (CIN2+) with these devices are non-inferior compared to that of conventional cryotherapy. The results of this study will affect other research areas by serving as a springboard to exploring treatment alternatives that are amenable to low-resource settings and thus will reach the most vulnerable populations.
E7 TCR T Cells for Human Papillomavirus-Associated Cancers
Papillomavirus InfectionsCervical Intraepithelial Neoplasia3 moreBackground: 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.
Vvax001 Cancer Vaccine in Premalignant Cervical Lesions - Phase II
CIN3Cervical Intraepithelial Neoplasia2 moreThis is an open label phase II study in patients with newly diagnosed human papilloma virus type 16 (HPV16) induced cervical intraepithelial neoplasia grade 3 (CIN3). Patients will be treated with three doses of Vvax001 immunization with an interval of 3 weeks between each immunization to induce histopathological regression and HPV clearance. Regression of CIN3 lesions will be monitored using colposcopy in week 9, week 17 and week 25. When complete regression of the CIN3 lesion is observed by colposcopy, a biopsy will be taken in week 25 to confirm regression histologically. A positive histologic regression is defined as a reduction from CIN3 to CIN1 or no dysplasia. Patients with a complete regression will not undergo the standard-of-care loop excision of the transformation zone (LETZ) and will be followed-up after the study by cytology at 3, 6 and 12 months. If complete regression has not occurred by 25 weeks, a standard-of-care LETZ will be performed.
Comparison of LLETZ Versus LEEP for the Treatment of Cervical Dysplasia
Cervical DysplasiaCervical dysplasia is the precursor of cervical cancer. LEEP and LLETZ are standard surgical procedures to treat cervical dysplasia. There is no direct head-to-head comparison between LEEP and LLETZ in the literature regarding oncologic safety, for which complete resection of the dysplastic lesion (so-called 'in-sano resection') is the most appropriate postoperative surrogate parameter. Further clinical studies are therefore useful to optimize surgical therapy for cervical dysplasia. The primary objective of the present study is to compare LLETZ (resection of the dysplastic lesion including the transformation zone) with targeted resection of the colposcopically conspicuous lesion only (LEEP) and to compare it with regard to oncological safety (defined as non-in-sano rate).
Artesunate Vaginal Inserts for the Treatment of Cervical Intraepithelial Neoplasia (CIN2/3)
CIN 2/3HPV Infection3 moreThis is a phase II double blind, placebo-controlled, randomized study of Artesunate vaginal inserts for the treatment of women who have cervical high grade intraepithelial neoplasia (CIN2/3).
HPV DNA Vaccine Via Electroporation for HPV16 Positive Cervical Neoplasia
Human Papillomavirus Type 16Cervical Intraepithelial Neoplasia Grade II2 moreThe primary goal of this phase I open label study is to determine the safety and tolerability of pNGVL4aCRTE6E7L2 DNA vaccine, as administered by intramuscular (IM) injection with TriGrid™ electroporation to both HIV- or HIV+ adult female subjects (≥ 19 years), with biopsy confirmed cervical intraepithelial (CIN) II or III that is human papillomavirus (HPV) 16+.
DEFLAGYN® Vaginal Gel and Spontaneous Remission and Regression of Unclear Cervical Smears and HPV...
Cervix DysplasiaHPV InfectionHuman papillomaviruses (HPV) are the most common sexually transmitted pathogens worldwide and in most cases are causally associated with the development of cervical cancer, one of the most common cancers in women and one of the leading causes of death in women worldwide. Precancerous lesions (dysplasias) or the presence of a high-risk HPV subtype are detected by a screening smear test performed by a gynecologist. If precancerous lesions are detected, conization (= surgical removal of a cone of tissue from the cervix) is the method of choice for removing the diseased tissue. However, if the degree of dysplasia is correspondingly low or the smear is unclear, then the guideline-compliant non-surgical treatment provides for a wait-and-see approach with PAP and HPV smear control after 6-8 months. This "wait-and-see" approach can be complemented by local therapy with an immunostimulant. For this purpose, DEFLAGYN® (a vaginal gel containing silica and citric acid) and Aldara® (imiquimod, a Toll-Like Re-ceptor 7 antagonist) are available. However, while the latter is not approved for the treatment of cervical dysplasia or HPV infection, DEFLAGYN® has CE marking and approval as a medical device for treatment in a number of indications, such as unclear cervical smears, HPV-induced cervical lesions, p16/Ki-67-positive cervical lesions or cervical erosions. However, available studies on the efficacy of DEFLAGYN are limited. For example, there is only one prospective randomized trial (Major et al, 2021, Arch. Gynecol. Obstet. 303:501-511), which included 216 women with histologically confirmed CIN 1/2. A 3-month intravaginal application of DEFLAGYN® resulted in regression of CIN 1/2 in 72% versus 25% in the control arm (no intervention). Side effects of therapy with DEFLAGYN® were not observed in this study. Due to the frequency of CIN and HPV infections in the female population and due to the high medical relevance of a conservative method of treating this disease, further methodologically high-quality studies on the efficacy of DEFLAGYN® should be performed.
