NCT02740998
Despite many years of research, controversy persists as to whether hormonal contraception promotes HIV acquisition. A number of observational studies on depot medroxyprogesterone acetate (DMPA) injection showed an increase in HIV risk and no evidence of increased risk with oral contraceptive pills. There are no human studies currently published on the impact of the levonorgestrel intrauterine device (LNG IUD) on HIV transmission risk and minimal data on the effects of the etonogestrel subdermal implant (ESI) on risk of HIV acquisition. Establishing whether any of these highly effective contraceptives increases the risk of HIV infection would have far-reaching public health implications, particularly in areas of high HIV prevalence such as sub-Saharan Africa, where injectable contraception accounts for nearly half of contraceptive use. Perturbations in the normal vaginal microbiota, or community of microorganisms inhabiting the vaginal body niche, have long been known to affect the risk of transmission of HIV. Studies have shown altered vaginal microbiota with DMPA injection and preserved vaginal microbiota with the LNG IUD, but no studies have compared these methods head-to-head or used culture-independent sequencing methodology. The investigators propose a prospective pilot study to evaluate the impact of different long-acting progestin contraceptive formulations on the vaginal microbiome. Specifically, the investigators aim to identify and compare metagenomics profiles associated with DMPA, LNG IUD, and ESI contraceptive use by community analysis of vaginal swab samples from women collected longitudinally after contraceptive method initiation. The investigators hypothesize that DMPA will increase community diversity in the vaginal microbiota, whereas the LNG IUD and ESI will not affect the balance of microorganisms in the vagina. Women who are planning to initiate DMPA, LNG IUD, and ESI contraception as well as controls not seeking contraception will be recruited for the study from Boston Medical Center (BMC), a tertiary care center with a racially and socioeconomically diverse patient population. Women will have longitudinal follow-up with self-sampling of the vagina for sexually transmitted infection testing and metagenomics analysis at method initiation, 2-3 months, and 6 months. Establishing the safest long-acting progestin contraceptive alternative will promote effective contraception use and lower rates of HIV acquisition worldwide.
NCT00552305
The purpose of this trial is to determine whether lacosamide is safe and effective for long-term use in patients with partial-seizures from epilepsy.
NCT01921751
This randomized phase II trial studies how well high or standard intensity radiochemotherapy after gemcitabine hydrochloride and paclitaxel albumin-stabilized nanoparticle formulation (nab-paclitaxel) work compared with gemcitabine hydrochloride and nab-paclitaxel alone in treating patients with pancreatic cancer that cannot be removed by surgery. Drugs used in chemotherapy, such as gemcitabine hydrochloride and nab-paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing or by stopping them from spreading. Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs, such as capecitabine, may make tumor cells more sensitive to radiation therapy. Giving radiation therapy in different ways and adding chemotherapy may kill more tumor cells. It is not yet known whether high intensity radiochemotherapy after gemcitabine hydrochloride and nab-paclitaxel is more effective than standard intensity radiochemotherapy after gemcitabine hydrochloride and nab-paclitaxel or gemcitabine hydrochloride and nab-paclitaxel alone in treating pancreatic cancer.
NCT00136214
The hypothesis of this study is that pegylated interferon would cause cognitive deficits and mood changes in hepatitis C (HCV) positive subjects.
NCT03381911
This study will investigate how consent forms and other health care documents are explained to patients. The findings will be used to create a computer program that can successfully explain consent and other health-related forms to individuals who have difficulty reading and understanding consent forms on their own as a supplement to the normal consent process done in research settings. In a prior study, the investigators delivered a similar protocol, where subjects were first consented and then given a mock consent form (administered in 1 of 3 arms: RA, ECA, or ECA + RA). Subjects in this protocol struggled with the concept of a "mock" consent process, especially after they had just completed a consent process for the study itself. The current protocol, using deception research methods, aims to provide a more pure assessment of ECA consent vs the standard (here, E-consent) by waiving consent and delivering the sham consent as if it were reality. In the context of a protocol that employs deception methods, participants in the current study would be invited as healthy volunteers, and be randomized to 1 of 2 different consent processes to evaluate the relative benefits of different approaches for informed consent. After the knowledge tests have been completed, subjects will undergo a debriefing where they are made fully aware of the deception and its purpose. At that time, subjects will also be given the opportunity to "opt out" and not have their data included in the study results.

General objective is to improve the convenience and quality of life of female patients who receive breast irradiation.
NCT00819585
The 24-week, dose-ranging, multi-center, double-blind, double-dummy, active-controlled core study investigated the prophylactic effect of canakinumab on the signs and symptoms of acute flares in chronic gout patients initiating allopurinol therapy. The core study was followed by a 24-week open-label, multicenter extension study to assess the safety, tolerability, and efficacy of canakinumab in patients with gout who were given canakinumab at the time of gout flare.
NCT02837822
It's well known that Spinal cord stimulation (SCS) changes the perception of chronic pain in the area stimulated by epidural electrodes. However, we don't know the effect of this type of stimulation on the perception of external sensations (temperature, touch, pressure, and vibration) and sharp pain. Quantitative sensory testing (QST) is used to quantify somatosensory phenotype. This QST battery tests different subtypes of nerve fibres (Aβ, Aδ and C) involved in the transduction of sensory information from the periphery to the spinal cord. The purpose of this study is to evaluate the effects of the SCS on sensory perceptions of patients with chronic pain (CRPS, FBSS). Sensorial perception tests will be carried out in accordance with a standardized procedure (Rolke et al. Pain, 2006). For non-implanted patients, an initial visit will be conducted before the operation. For all participants, two other visits will take place at least 6 months after the operation to perform the tests with and without stimulation.
NCT03413644
Multi-center study of specimens from subjects presenting to the flow cytometry laboratory as part of their standard of care for hematological diseases work-up.
NCT00668148
This multicenter study will enroll approximately 185 participants with metastatic or advanced sarcoma, to assess the effectiveness and safety of IMC-A12 monotherapy for this indication. Participants will be stratified into five tiers according to diagnosis: 1. Ewing's sarcoma/peripheral neuroectodermal tumor (PNET) 2. rhabdomyosarcoma 3. leiomyosarcoma 4. adipocytic sarcoma 5. synovial sarcoma. A total of 85 participants will be enrolled initially, 17 in each tier. Participants will receive single agent IMC-A12 every 2 weeks. A treatment cycle will be defined as 6 weeks, with radiological evaluation at every cycle. Safety and response in the initial 17 participants in each tier will be used to determine whether to extend enrollment to the target total of 37 participants per tier.
NCT02345161
This is a phase IIIa, randomised, double-blind, double-dummy, parallel group multicenter study evaluating once daily FF/UMEC/VI (100 microgram \[mcg\]/62.5 mcg/25 mcg) inhalation powder versus twice daily budesonide/formoterol (400 mcg/12 mcg). The primary purpose of this study is to demonstrate improvements in lung function and health status for subjects treated with FF/UMEC/VI compared with budesonide/formoterol for 24 weeks. Once-daily 'closed' triple therapy of a Inhaled Corticosteroid/ Long-acting Muscarinic Receptor Antagonists/ Long Acting Beta-Agonist (ICS/LAMA/LABA) combination FF/UMEC/VI (100 mcg/62.5 mcg/25 mcg) in a single device is being developed with the aim of providing a new treatment option for the management of advanced (GOLD Group D) COPD which will reduce the exacerbation frequency, allow for a reduced burden of polypharmacy, convenience, and increase the potential for improvement in lung function, Health Related Quality of Life (HRQoL) and symptom control over established dual/monotherapies. Subjects meeting all inclusion/exclusion criteria and who have successfully completed all protocol procedures at the Screening Visit will enter the two-week run-in period. Following the run-in period, eligible subjects will be randomised (1:1) to one of the following double-blind treatment groups: FF/UMEC/VI 100 mcg/62.5 mcg/25 mcg via the ELLIPTA™ dry powder inhaler (DPI) once daily in the morning and placebo via reservoir inhaler twice daily OR Budesonide/formoterol 400 mcg/12 mcg via reservoir inhaler twice daily and placebo via the ELLIPTA DPI once daily in the morning. The target enrollment is 1800 randomised subjects at approximately 200 study centers globally. The total duration of subject participation will be approximately 27 weeks, consisting of a 2-week run-in period, 24-week treatment period and a 1-week follow-up period. Subjects will run-in on their existing COPD medications for 2 weeks and in addition will be provided with short acting albuterol/salbutamol to be used on an as-needed basis (rescue medication) throughout the study. Subjects will discontinue all existing COPD medications during the randomised treatment period but may continue their study supplied rescue albuterol/salbutamol. A sub-set of approximately 400 subjects will remain on blinded study treatment for up to a total of 52 weeks to provide additional long term safety data.
