Filter by:This study will determine whether Synergo® RITE + MMC treatment is efficacious as second-line therapy for CIS NMIBC BCG-unresponsive patients with or without papillary NMIBC, through examination of the complete response rate (CRR) and disease-free duration for complete responders. The study will also explore progression-free survival time, bladder preservation rate, and overall survival time. The study will address an unmet need to identify a treatment effective in both ablating the disease and providing a prolonged disease-free period for patients. Ideally, the treatment will delay progression to invasive disease, thus preserving the bladder.
The purpose of this first in human and proof of concept study is to characterize the safety, tolerability and initial efficacy of CLL442 in patients with Squamous Cell Carcinoma in situ (SCCis) to enable further clinical development of CLL442.
The purpose of this study is to test if an experimental drug called Durvalumab (Medi4736) given by intravenous (IV) infusion is effective in treating carcinoma in situ (CIS) of the bladder that no longer responds to Bacillus Calmette-Guérin (BCG) and to collect information on the safety of these drugs and whether they cause any side effects.
This is an open-label, non-randomized pharmacokinetic study of fulvestrant in women scheduled for mastectomy or lumpectomy. Eligible subjects will be identified with breast cancer or DCIS. The first subject of each of five groups will receive fulvestrant intramuscularly. The subsequent 5 subjects of each group will receive fulvestrant by intraductal instillation. All subjects will be monitored for systemic and local adverse events during the procedure, and following the procedure until mastectomy or lumpectomy. Subjects that receive fulvestrant will undergo serial blood draws to determine fulvestrant blood concentration levels.
This research trial studies two types of tests, an ultrasound test and a biomarker test, to see how well they predict how aggressive (invasive) bladder cancer is in samples from patients with bladder cancer. The aggressiveness of a tumor means how likely it is to invade the body and spread. The ultrasound test uses a fluorescent dye and stimulates cells under a microscope to see how they respond. This may allow doctors to predict how likely the cancer cells are to spread in the body. The biomarker test uses laboratory testing of samples from patients to study genes and other molecules that may predict the cancer invasiveness. Comparing two different ways of predicting cancer aggressiveness may help doctors identify how well they work, and may eventually allow doctors to predict aggressiveness without needing to take a biopsy.
Rationale: Cervical Intraepithelial Neoplasia (CIN) is the premalignant condition of cervical cancer. High grade CIN (CIN 2-3) is currently treated by large loop excision of the transformation zone (LLETZ). This treatment has potential complications, such as hemorrhage, infection and preterm birth in subsequent pregnancies. For this reason, non-invasive therapies are needed. Imiquimod (an immunomodulator) was proven effective in the treatment of HPV-related vulvar intraepithelial neoplasia (VIN) and may also be effective in HPV-related CIN. [van Seters, 2012] However, the evidence is limited and study results are not consistent. [Grimm, 2012; Pachman, 2012; Lin, 2012] Objectives: Primary objectives: (1) to investigate the efficacy of imiquimod 5% cream for the treatment of CIN2-3 lesions and (2) to develop biomarker panels to predict clinical response to imiquimod therapy. Secondary objectives: to assess side effects of imiquimod treatment and LLETZ, disease recurrence and quality of life. Hypothesis: The investigators hypothesize that imiquimod will be an effective treatment modality in approximately 50-75% of CIN lesions treated without surgical intervention. Study design: Single-centre randomized controlled intervention trial. Study population: 140 women with a histological diagnosis of CIN2-3, equally divided over two study arms. Intervention: Patients will be randomized into one of two arms: 1. Imiquimod treatment arm. Patients in this group are treated by a 16-week regime of imiquimod 5% cream. 2. Standard treatment arm. LLETZ will be performed on patients in this group. Colposcopy with diagnostic biopsies will be performed after 10 weeks for the imiquimod treatment arm. In case progressive disease, the treatment will be ended and appropriate surgical excision will be performed. Treatment efficacy will be evaluated after 20 weeks, by colposcopy with diagnostic biopsies. A histological biomarker panel will be developed, consisting of markers representing both host and viral factors. Main study parameters/endpoints: The primary endpoint of the study is regression-or-not of CIN2-3, defined as CIN1 or less at the colposcopy at 20 weeks for the imiquimod arm and PAP 1 cytology at 6 months for the LLETZ group.
Currently, colonoscopy is the safest way to detect bowel tumors and polyps, since these can be biopsied and removed in one working process. If the size of adenomas is larger than 2 cm, resections are usually done in a hospital setting. For the resection of large adenomas, different approaches can be used. The so-called piecemeal resection is done with snares, to cut off parts of the adenoma piece by piece until the whole adenoma is resected. This technique is the standard therapy, but is not required for very large adenomas, which can often show cell alterations that indicate cancer. Therefore these adenomas should be resected in one piece. This is done by the so-called en-bloc resection. For this kind of therapy, different endoscopic knifes are use to cut off the adenoma as a whole. Both resection techniques are done usually by previous injection of saline or other liquids to elevate the lesion from its bottom tissue. Although the piecemeal resection of large adenoma is the standard therapy, it shows recurrence rates of 10 to 25%, which afford repeated therapies and follow up controls. En-bloc resections, though, are expected to have less recurrence rates but are much more complex to perform. They have higher complication rates especially in the West, where it has bee introduced only a couple of years ago. The data situation regarding safety and efficacy of both therapies is low. This study is the first one ever to compare piecemeal EMR and ESD in a randomized way. The study might have influence on the logistics of future adenoma processing and patient flow.
Naltrexone is a drug which blocks some effects of chemicals called beta-endorphins that are made in the body. Beta-endorphins can be made in response to stress, injury, and also pleasurable activities. In previous studies, it has been shown that levels of beta-endorphins in the blood go up during radiation therapy, and that this increase is linked to fatigue. This suggests that naltrexone may help to reduce fatigue in people who are getting radiation therapy In this research study, the investigators are looking to see whether naltrexone works better than a placebo in reducing fatigue during radiation therapy.
The purpose of this study is to examine the genetic material called microRNA of three types of specimens from women with breast cancer. The study also seeks to examine the effectiveness of using a new agent called oxytocin to increase the amount of nipple fluid that can be collected during surgery.
This pilot clinical trial studies interactive gentle yoga in improving quality of life in patients with stage I-III breast cancer undergoing radiation therapy. Interactive gentle yoga may improve the quality of life in patients with breast cancer undergoing radiation therapy.
