The purpose of this study is to estimate Abatacept steady-state trough concentration (Cmin) at Day 113 in children and adolescents with pJIA
NCT00074165
RATIONALE: Monoclonal antibodies, such as rituximab, can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Drugs used in chemotherapy, such as carboplatin, cyclophosphamide, etoposide, etoposide phosphate, and cytarabine, use different ways to stop cancer cells from dividing so they stop growing or die. Osmotic blood-brain barrier disruption uses certain drugs to open the blood vessels around the brain and allow anticancer substances to be delivered directly to the brain tumor. Chemoprotective drugs such as sodium thiosulfate may protect normal cells from the side effects of carboplatin-based chemotherapy. Combining rituximab with chemotherapy given with osmotic blood-brain barrier disruption plus sodium thiosulfate may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of combining rituximab with combination chemotherapy given with osmotic blood-brain barrier disruption plus sodium thiosulfate in treating patients who have refractory or recurrent primary CNS lymphoma.
NCT03118570

NCT00008385
RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. It is not yet known if selenium is effective in preventing the growth of new tumors in patients with previously resected non-small cell lung cancer. PURPOSE: This randomized phase III trial is studying selenium to see how well it works compared to a placebo in preventing the development of second primary lung tumors in patients who have undergone surgery to remove stage I non-small cell lung cancer.
NCT00902720
The purpose of this study is to offer an alternative method to women who wish to preserve the possibility of fertility, as well as to learn more about the ability of human eggs to survive and function after long term storage in frozen ovaries (ovarian tissue cryopreservation). The study will seek to preserve ovarian tissue and reproductive potential for patients whose medical or surgical treatment may harm ovaries or remove ovarian tissue.
NCT00304239
The purpose of this study was to compare the efficacy of Photodynamic Therapy (PDT) with methyl aminolevulinate (MAL) cream to PDT with vehicle cream, using the Light-emitting diode (LED) light source Aktilite CL128, in treatment of participants with multiple actinic keratosis (sun-damaged skin) on the face and/or scalp.
NCT01107626
RATIONALE: Drugs used in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of non-small cell lung cancer by blocking blood flow to the tumor. Pemetrexed disodium may stop the growth of tumor cells by blocking some enzymes needed for cell growth. It is not yet known whether giving bevacizumab or pemetrexed disodium alone or in combination is more effective in treating non-squamous non-small cell lung cancer. PURPOSE: This randomized phase III trial is studying bevacizumab and pemetrexed disodium alone or in combination after induction therapy to see how well they work in treating patients with advanced non-squamous non-small cell lung cancer.

NCT03384446
Dental implants have revolutionized the field of dentistry, providing improvements in function and esthetics. They are not, however, without risks. Bone loss around implants (i.e. periimplantitis) is an emerging public health concern. Untreated, peri-implantitis leads to implant loss and jawbone defects. Nonetheless, existing therapies have failed to show long-term efficacy. The pathogenesis of peri-implantitis is believed to be of bacterial etiology similar to periodontal disease. Therefore, existing treatments duplicate strategies for the treatment of natural teeth. However, the titanium (Ti) surface of implants is quite dissimilar to teeth. Recent work from our lab has demonstrated that peri-implantitis is associated with increased release of Ti particles around implants. These findings suggest that treatments targeting periimplantitis must be designed around Ti material properties. A gap in knowledge exists regarding the potential triggers of increased Ti dissolution from the implant surface and the mechanisms by which Ti dissolution products amplify peri-implant inflammation. The aim of this study is to determine if the use of tooth-driven treatment approaches increase Ti in the submucosal plaque.
NCT02267603
This phase II trial studies how well pembrolizumab works in treating patients with Merkel cell cancer that cannot be removed by surgery or controlled with treatment, or has spread to other parts of the body. Pembrolizumab may stimulate the immune system to identify and destroy cancer cells.
NCT00057876
RATIONALE: Drugs used in chemotherapy 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. It is not yet known whether gemcitabine is more effective with or without radiation therapy in treating pancreatic cancer. PURPOSE: Randomized phase III trial to study the effectiveness of gemcitabine with or without radiation therapy in treating patients who have locally advanced, unresectable pancreatic cancer.
NCT03459807
Blood pressure may be one of the most important modifiable risk factors for cardiovascular disease in patients with end-stage-renal-disease undergoing maintenance hemodialysis. Although a systolic blood pressure \<140 mmHg treatment target has been recommended, there remains uncertainty on which blood pressure should be targeted, more specifically that measured in the dialysis unit or at home. Observational studies have reported a paradoxical U-shaped associated with dialysis unit (pre-dialysis) systolic blood pressure and cardiovascular events and death (where blood pressure below 140 mmHg is actually linked with poor outcomes). Conversely, the same studies have reported a linear association between higher home systolic blood pressure and worse clinical outcomes, where blood pressure below 140 mmHg is associated with better outcomes. This pilot clinical trial aims to address this important question.
NCT02193841
Simple bone cysts (SBCs) are cysts filled with fluid that occur most frequently in the long bones (arms or legs) of children. There are many ways to treat SBCs but it is unclear if one is better than another. The purpose of this research trial is to compare the effectiveness of two common treatments that are used by surgeons today.
NCT03911492
This multicenter study will enroll 100 patients with acute traumatic cervical and thoracic SCI who have a lumbar intrathecal catheter inserted within 24 hours of their injury. The lumbar intrathecal catheter will be inserted pre-operatively for the measurement of ITP and the collection of cerebrospinal fluid (CSF) samples. SCPP will be calculated as the difference between MAP and the ITP. There are two important distinct yet related objectives in this prospective interventional study. 1. Determine the effect of SCPP maintenance ≥ 65 mmHg in acute SCI on neurologic recovery as measured by ASIA Impairment Scale (AIS) grade conversion and motor score improvement. 2. Collect CSF and blood samples for the measurement of neurochemical biomarkers and storage for future biomarker discovery and validation studies.
NCT02482311
This is an open-label, multi-centre, Phase Ib study of AZD1775 designed to assess the safety, tolerability, pharmacokinetics, and anti-tumour activity of AZD1775 monotherapy in patients with advanced solid tumours.
NCT01216683
RATIONALE: Drugs used in chemotherapy, such as bendamustine hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Biological therapies, such as lenalidomide, may stimulate the immune system in different ways and stop cancer cells from growing. It is not yet known whether giving bendamustine hydrochloride and rituximab together alone is more effective than giving bendamustine hydrochloride and rituximab together with bortezomib or lenalidomide in treating follicular lymphoma. PURPOSE: This randomized phase II trial is studying giving bendamustine hydrochloride and rituximab together with or without bortezomib followed by rituximab with or without lenalidomide to see how well they work in treating patients with high-risk stage II, stage III, or stage IV follicular lymphoma.
NCT00091169
RATIONALE: Levocarnitine may help improve energy levels in cancer patients. PURPOSE: This randomized phase III trial is studying how well levocarnitine works compared to a placebo in treating fatigue in cancer patients.
NCT00335140
RATIONALE: Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some find cancer cells and kill them or carry cancer-killing substances to them. Others interfere with the ability of cancer cells to grow and spread. Drugs used in chemotherapy, such as methotrexate, leucovorin, vincristine, procarbazine, dexamethasone, and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving rituximab together with combination chemotherapy may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving rituximab together with combination chemotherapy works in treating patients with primary central nervous system (CNS) lymphoma.
NCT00316888
RATIONALE: Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some find tumor cells and kill them or carry tumor-killing substances to them. Others interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as cisplatin and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Cetuximab may help cisplatin and fluorouracil work better by making tumor cells more sensitive to the drugs. It may also make tumor cells more sensitive to radiation therapy. Giving cetuximab together with chemotherapy and radiation therapy may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving cetuximab together with cisplatin, fluorouracil, and radiation therapy works in treating immunocompetent patients with stage I (closed to accrual as of 11/3/2008), stage II, (some stage II closed to accrual as of 11/3/2008) or stage III anal cancer.
