NCT02538341
The VaricElla zosteR VaccinE (VERVE) trial evaluates the safety and effectiveness of the Herpes zoster (HZ) vaccine for shingles, Zostavax, in patients over 50 years old with arthritis and other diseases who are using anti-tumor necrosis factor (TNF) therapy and who have not previously received the vaccine.
NCT03383146
A 52-week study to compare the efficacy of relamorelin with that of placebo in participants with diabetic gastroparesis (DG) with respect to the core signs and symptoms of diabetic gastroparesis.
NCT00094016
The primary objective of this study is to compare the QVAR-Easi-Breathe 100 mcg/day and QVAR-Easi-Breathe 200 mcg/day with placebo relative to changes in forced expiratory volume in 1 second (FEV1) results following 12 weeks of treatment. Secondary objectives such as daily asthma symptoms scores (per week), morning peak expiratory flow (PEF) values, nocturnal awakening and utilization of rescue medication per day also will be evaluated. In addition, an exploratory evaluation will assess the comparability of the two devices (i.e., QVAR-Easi-Breathe versus QVAR-MDI) at the same dose levels.
NCT00075582
This phase III trial is studying how well combination chemotherapy and radiation therapy work in treating patients with newly diagnosed low-risk rhabdomyosarcoma. Drugs used in chemotherapy, such as vincristine, dactinomycin, and cyclophosphamide, work in different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining chemotherapy with radiation therapy may kill more tumor cells. It is not yet known which treatment regimen is more effective in treating low-risk rhabdomyosarcoma.
NCT03123588
The purpose of this study is to evaluate the efficacy and safety of ruxolitinib versus anagrelide in subjects with essential thrombocythemia who are resistant to or intolerant of hydroxyurea.
NCT03433950
Current management of hypertension in PD motor fluctuators is flawed. The current practice often is to treat transient hypertensive spikes reported by patients or measured in clinics with anti-hypertensive medications. This may contribute to morbidity by worsening orthostatic hypotension and increasing fall risk. There is a scarcity of literature on this subject and there is no documentation of severe hypertension with rises in systolic blood pressure exceeding 50% of baseline occurring during motor "OFF". There are two studies that have demonstrated that blood pressure fluctuation can occur in motor fluctuators during the "OFF" state1,2. The study by Baratti et al measured blood pressure in 13 Parkinson's disease patients, 7 with motor fluctuations and 6 without fluctuations. In the fluctuators, the mean systolic/diastolic blood pressures were significantly higher than the non-fluctuators during the "OFF" state but not the "ON" state.
NCT02129075
This phase II trial studies the effect of a vaccine called CDX-1401 given with or without a biologic drug called CDX-301 in treating patients with stage IIB-IV melanoma. The cancer vaccine CDX-1401 attaches to a protein that is made in tumor cells. The vaccine helps the body recognize the tumor to fight the cancer. The biologic drug CDX-301 may help the body make more of the tumor fighting cells, known as dendritic cells. Another biologic drug, poly-ICLC, may stimulate the immune system and help these dendritic cells mature so that they can recognize the tumor. Giving CDX-301 may make the immune response to a combination of CDX-1401 and poly-ICLC better.
NCT03363256
The purpose of the current study is to evaluate the preliminary efficacy of the Therapeutic Education System-Native Version (TES-NAV) (an efficacious web-delivered psychosocial intervention for substance use disorders adapted with American Indians/Alaska Natives \[AI/AN\]) to determine whether a future large-scale effectiveness trial is warranted. Specifically, a randomized controlled trial among urban AI/AN (N=80) attending outpatient addiction treatment services will be conducted to (1) estimate preliminary effect size of 12 weeks of TES-NAV on substance use disorder outcomes; (2) explore relevant moderators of TES-NAV outcomes; and (3) assess cultural factors that may correspond to variation in outcome.
NCT02139644
The primary objective of this study was to evaluate the efficacy of fluticasone propionate multidose dry powder inhaler (Fp MDPI) and fluticasone propionate/salmeterol xinafoate multidose dry powder inhaler (FS MDPI) when administered over 12 weeks in patients 12 years of age and older with persistent asthma. Study drug and placebo was supplied in Teva multidose dry powder inhaler (MDPI) devices and provided for participants to use at home. Participants performed spirometry at every visit. Each participant was given a diary at each visit for use until the next visit. Rescue medication (albuterol/salbutamol) was dispensed at each visit, if needed, as determined by the investigational center personnel.
NCT02315469
This research trial studies comprehensive patient questionnaires in predicting complications in older patients with gynecologic cancer undergoing surgery. Comprehensive patient questionnaires completed before surgery may help identify complications, such as the need for assistance in taking medications, decreased mobility, decreased social activity, and falls, and may improve outcomes for older patients with gynecologic cancer.
NCT03018249
This randomized surgical window trial evaluates the effect of adding entinostat to medroxyprogesterone acetate before surgery works on progesterone receptors on endometrioid endometrial tumors. Medroxyprogesterone acetate is a progesterone, a hormone produced by body normally. Entinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving medroxyprogesterone acetate with or without entinostat may effect tumors from endometrioid endometrial cancer.
NCT01324232
The objectives of the study are to evaluate the safety, tolerability, and efficacy of 3 doses of AVP-923 capsules in the treatment of central neuropathic pain in participants with multiple sclerosis.
NCT00118209
This randomized phase III trial studies rituximab when given together with two different combination chemotherapy regimens to compare how well they work in treating patients with diffuse large B-cell non-Hodgkin's lymphoma. Monoclonal antibodies, such as rituximab, may block cancer growth in different ways by targeting certain cells. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving rituximab together with combination chemotherapy may kill more cancer cells. It is not yet known which combination chemotherapy regimen is more effective when given with rituximab in treating diffuse large B-cell non-Hodgkin's lymphoma. PURPOSE: This randomized phase III trial is studying rituximab when given together with two different combination chemotherapy regimens to compare how well they work in treating patients with diffuse large B-cell lymphoma.
NCT03548935
This study will look at the change in participants' body weight from the start to the end of the study. The weight loss in participants taking semaglutide (a new medicine) will be compared to the weight loss of participants taking "dummy" medicine. In addition to taking the medicine, participants will have talks with study staff about healthy food choices, how to be more physically active and what you can do to lose weight. Participants will either get semaglutide or "dummy" medicine - which treatment participants get, is decided by chance. Participants will need to take 1 injection once a week. The study medicine is injected with a thin needle in a skin fold in the stomach, thigh or upper arm. The study has two phases: A main phase and an extension phase.The main phase will last for about 1.5 years. Participants will have 15 clinic visits and 10 phone calls with the study doctor. Extension phase: Approximately 300 participants will continue in the extension phase in the following countries only: Canada, Germany, the UK and selected sites in the US and Japan. These participants will be in the study for about 2.5 years.They will not receive treatment, but will attend another 5 follow-up visits with the study doctor.
NCT03095287
This is a multicenter, multinational, prospective, single-arm, nonrandomized, open-label study, planned in of approximately 25 male participants with congenital hemophilia A who will receive their first (primary) immune tolerance induction (ITI) treatment with alphanate. The study consists of 2 phases: * An ITI Treatment Phase in which all eligible participants will receive ITI treatment with alphanate for a period of up to 33 months. Upon confirmation of complete immune tolerization, participants will then enter a 12-month Prophylactic Phase. If, after 33 months of ITI, a participants has achieved partial immune tolerance, the participants will enter a 12-month Prophylactic Phase. * A 12-month Prophylactic Phase for all participants who meet the criteria for complete or partial success to continue on a prophylactic dosing regimen of alphanate. Due to limited enrollment, this study was early terminated.
NCT02055781
Phase 3, randomized, controlled study to evaluate the safety and efficacy of oral pacritinib compared to Best Available Therapy (BAT) in patients with thrombocytopenia and primary or secondary myelofibrosis.
NCT04358068
The purpose of this study was to evaluate the efficacy of hydroxychloroquine (HCQ) and azithromycin (Azithro) to prevent hospitalization or death in symptomatic adult outpatients with COVID-19 caused by SARS-CoV-2 infection.
NCT02625909
The aim of the study is to determine if treatment for recently acquired hepatitis C infection (with or without HIV coinfection) can be shortened when treating with the interferon-free therapy sofosbuvir/velpatasvir (SOF/VEL). SOF/VEL is a new treatment for hepatitis C called direct acting antiviral which targets the hepatitis C virus replication cycle and has been shown in phase II studies in chronic HCV to be highly effective (SVR12 \>95%) when given for 12 weeks. Data has shown that treatment can be shortened when treating recently acquired HCV with interferon containing treatments. It is not known whether treatment with SOF/VEL can be shortened. This study aims to find out if treatment for 6 weeks with open-label SOF/VEL is equivalent to treatment for 12 weeks with SOF/VEL in participants with recently acquired hepatitis C infection. The project is a randomised study where both participants and investigators would not find out the treatment duration of the participants until week 6 of treatment.
NCT02120157
This is a multi-institutional phase II haploidentical T cell replete bone marrow transplant (BMT) study in children with high-risk leukemia. The myeloablative conditioning regimen prescribed will be Total body irradiation (TBI)-based for lymphoid leukemia and busulfan-based for myeloid leukemia. Our goal is to establish an easily exportable, inexpensive platform for haplotransplantation that has a safety profile equivalent to matched related and unrelated BMTs. The primary objective will be to estimate the incidence of 6-month non-relapse mortality (NRM), hypothesizing that NRM is \< 18%.
