NCT ID: NCT03335059 Terminated - Bladder Cancer Clinical Trials

Mitomycin C Intravesical Chemotherapy in Conjunction With Synergo® Radiofrequency-Induced Hyperthermia for Treatment of Carcinoma in Situ Non-Muscle Invasive Bladder Cancer Patients Unresponsive to Bacillus Calmette-Guérin, With or Without Papillary Tumors.

RITE-USA
Start date: April 4, 2019
Phase: Phase 3
Study type: Interventional

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.

Phase: Phase 2
Study type: Interventional

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.

NCT ID: NCT02876640 Terminated - Clinical trials for Anatomic Stage II Breast Cancer AJCC v8

Retinoid 9cUAB30 in Producing a Biologic Effect in Patients With Early Stage Breast Cancer

Start date: March 16, 2018
Phase: Phase 1
Study type: Interventional

This phase 1b trial studies the biologic effect of 9cUAB30 on early stage breast cancer. 9cUAB30 is a retinoid X receptor (RXR)-selective retinoid that acts in a tissue selective manner with the goal of minimizing side effects, a necessary feature of agents under development for cancer prevention.

NCT ID: NCT02540330 Terminated - Clinical trials for Female Breast Carcinoma

A Pre-Surgical PK Study of IM and Intraductally Delivered Fulvestrant

007
Start date: March 2016
Phase: Phase 2
Study type: Interventional

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.

NCT ID: NCT02494635 Terminated - Clinical trials for Stage II Bladder Urothelial Carcinoma

Ultrasound and Biomarker Tests in Predicting Cancer Aggressiveness in Tissue Samples of Patients With Bladder Cancer

Start date: September 16, 2015
Phase:
Study type: Observational

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.

NCT ID: NCT02329171 Terminated - Clinical trials for Cervical Intraepithelial Neoplasia

Imiquimod Treatment of CIN Lesions

TOPIC
Start date: December 2014
Phase: Phase 3
Study type: Interventional

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.

NCT ID: NCT02238938 Terminated - Clinical trials for Colorectal Adenomatous Polyp

Piecemeal Versus En Bloc Resection of Large Rectal Adenomas

PERLA
Start date: April 2014
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT02137252 Terminated - Clinical trials for Ductal Carcinoma in Situ

Naltrexone RCT for Treatment-Emergent Fatigue in Patients Receiving Radiation Therapy for Breast Cancer

Start date: May 2014
Phase: Phase 2
Study type: Interventional

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.

NCT ID: NCT02127073 Terminated - Breast Cancer Clinical Trials

Pilot Study of Oxytocin and microRNA Identification in NAF, Serum, and Tissue in Women With Breast Cancer

Start date: January 30, 2015
Phase: Phase 2
Study type: Interventional

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.
