NCT01103349
This is a 6 week study to assess the effect of BI 671800 in patients with asthma. It is a double blind, parallel arm trial testing the safety and efficacy of BI 671800. The main objective is to assess the effect on lung function. The study will also provide data on the pharmacokinetics of BI 671800.
NCT03365791
The purpose of this signal seeking study is to determine whether treatment with PDR001 and LAG525 demonstrates sufficient efficacy in advanced malignancies to warrant further study.
NCT02647359
This study is designed to evaluate the effect of ataluren on Maximum Reading Speed as measured using the Minnesota Low Vision Reading Test (MNREAD) Acuity Charts in participants with nonsense mutation aniridia. This study involves a 4-week screening period, a 144-week treatment period (Stage 1: Weeks 1 to 48 \[double-masked treatment\] and Stage 2: Weeks 49 to 144 \[open label treatment\]), an optional 96-week open label extension sub-study, and a 4-week post-treatment follow-up period (either study completion or early termination). Participants that choose not to participate in the sub-study will be required to complete the post-treatment follow-up visit at the end of the Stage 2 open-label extension.
NCT00003857
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using tamoxifen may fight breast cancer by blocking the uptake of estrogen by the tumor cells. It is not yet known if radiation therapy is more effective than observation, with or without tamoxifen, in treating ductal carcinoma in situ. PURPOSE: Randomized phase III trial to compare the effectiveness of radiation therapy with that of observation, with or without tamoxifen, in treating women who have ductal carcinoma in situ.
NCT02999854
The primary objective of this study is to compare safety and efficacy of a haploidentical T-cell depleted HSCT and adjunctive treatment with ATIR101 versus a haploidentical T cell replete HSCT with post-transplant administration of high dose cyclophosphamide (PTCy) in patients with a hematologic malignancy. An additional objective of the study is to compare the effect of the two treatments on quality of life.
NCT02839343
This randomized phase II trial studies how well combination chemotherapy (mFOLFIRINOX) with or without hypofractionated radiation therapy before surgery works in patients with pancreatic cancer that can be removed by surgery. Drugs used in combination chemotherapy, such as oxaliplatin, leucovorin calcium, fluorouracil, and irinotecan hydrochloride, 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. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects. It is not yet known if combination chemotherapy is more effective with or without hypofractionated radiation therapy before surgery in treating patients with pancreatic cancer.
NCT03444753
The purpose of this study is to determine whether BMS-986299 both by itself and in combination with Nivolumab and Ipilimumab is safe and tolerable in the treatment of advanced solid tumors. In addition, the ability of study drugs to stimulate an immune response against cancer will be investigated.
NCT03395704
This study is a Phase 2 multicenter, randomized, placebo controlled, single-blind study. The primary objective of the study is to compare the effect of weekly dosing of LJPC-401 (synthetic human hepcidin) versus placebo on transferrin saturation (TSAT) in an adult hereditary hemochromatosis patient population.
NCT03951077
This study will assess the potential impact of elagolix on disordered pituitary and ovarian hormones in women with polycystic ovary syndrome (PCOS).
NCT01263600
The purpose of this study is to describe participants 6 months to \<18 years of age with hepatitis B virus (HBV) infection in a prospective cohort in the United States (US) and Canada and identify predictors of disease activation and progression.
NCT02593071
This study will enroll subjects who received the RSV F vaccine or placebo in the earlier study (RSV-E-201, Year 1) and re-randomize them to receive either vaccine or placebo in a second season. This design will permit evaluation of the safety and immunogenicity of revaccination in a second RSV season, and the safety and immunogenicity of revaccination over two years.
NCT01369199
The investigators evaluated the safety and efficacy of a short lead-in course (8 weeks) of entecavir followed by combination of entecavir plus peginterferon alfa-2a for 40 weeks.
NCT02611830
The purpose of this study is to assess the effect of vedolizumab subcutaneous (vedolizumab SC) maintenance treatment on clinical remission at Week 52 in participants with moderately to severely active ulcerative colitis (UC) who achieved clinical response following administration of vedolizumab intravenous (vedolizumab IV) induction therapy.
NCT02210650
Patients with a ureteral or kidney stone that causes symptoms, like pain, frequently have small kidney stones that don't cause symptoms. If these small kidney stones are determined to be asymptomatic (not causing any problems or pain), then most urologists will simply remove the symptomatic ureteral stone and leave the additional stones in the kidneys. However, symptomatic kidney stones started as small stones that didn't cause symptoms. This means that the small stones remaining in the patient's kidney may cause problems later. The purpose of our research is to test if removing small stones from the kidney prevents future stone episodes.
NCT03548220
Study AG348-C-006 evaluated the efficacy and safety of orally administered AG-348 as compared with placebo in participants with pyruvate kinase (PK) deficiency, who were not regularly receiving blood transfusions. Participants were randomized 1:1 to receive either AG-348 or a matching placebo.
NCT03007888
Primary Objective: To compare the pharmacokinetics (PK) of single and multiple doses of IPX203 with Immediate release carbidopa-levodopa (IR CD-LD) in subjects with advanced Parkinson's disease (PD). Secondary Objectives: To compare the pharmacodynamics of single and multiple doses of IPX203 with IR CD-LD. To compare the efficacy of IPX203 with IR CD-LD following multiple doses. To evaluate the safety of IPX203.
NCT00370604
The purpose of this study is to determine the effect of 19g versus =\>18g traditional Tuohy-type epidural needles on the incidence and severity of postdural puncture headache (PDPH).
NCT01968590
This clinical trial is conducted by one of 4 locations; University of British Columbia (Vancouver, CA), University of Utah (Salt Lake City, UT, USA), University of Cincinnati (Cincinnati, OH, USA), and University of Hamburg (Hamburg, Germany). Adults with NF1 have a higher risk of osteopenia and osteoporosis, a condition of low bone density that can lead to fragile bones and bone breakage. People with NF1 also have lower vitamin D levels than unaffected individuals. Vitamin D is important for normal bone health, but studies to improve bone health by vitamin D supplementation in people with NF1 have not been tried. The purpose of this study is to treat adults with NF1 who have insufficient serum vitamin D levels with 2 different doses of vitamin D supplementation to determine if vitamin D supplementation ameliorates the usual loss of bone mineral density over 2 years.
NCT01434290
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Given radiation therapy in different ways may kill more tumor cells. PURPOSE: This randomized phase II trial studies radiation therapy to see how well it works in treating patients with prostate cancer.
NCT04070326
The main aims of this study are to learn how lanadelumab moves through a child's body and if the children have any medical problems from lanadelumab. Other aims are to learn if prophylactic treatment with lanadelumab reduces the number and severity of HAE attacks in children, how lanadelumab affects the child's body, and if the children develop antibodies to lanadelumab. The study doctors will treat acute HAE attacks according to their standard practice. Participants will receive lanadelumab for up to 52 weeks. When they start treatment, participants will visit their clinic every week for the first 4 weeks. Then, they will visit their clinic every 4 weeks during treatment.
