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.
NCT02610075
This Phase Ib study will identify the Maximum Tolerated Dose (MTD) of AZD1775 monotherapy when administered orally once daily (QD) or two times per day (BID) on Days 1 to 5 followed by 9 days of rest in 14-day cycles, or QD on a 5/2 dosing schedule (5 days on, followed by 2 days rest) in 21-day cycles in patients with locally advanced or metastatic solid tumours. Alternative treatment schedules may be explored if preliminary data suggest these would be more appropriate. The effect of food on single dose PK of AZD1775 will be assessed in 12 patients. In this sub-study, patients will receive a single oral dose of AZD1775 with 240 mL of water, once in the fasted state and once following a high-fat meal.
NCT04705597
The primary objectives of this study are to evaluate the safety, tolerability, and efficacy of BGE-175 in participants ≥ 50 years of age hospitalized with documented COVID-19.
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.
NCT04406649
Study STS101-003 is a multi-center, multiple dose (PRN), open-label, 12-month study to evaluate the safety and tolerability of STS101 (dihydroergotamine nasal powder) in the acute treatment of migraine.
NCT00064350
RATIONALE: Preclinical studies indicate that sorafenib is a potent inhibitor of Raf kinase in vitro and in vivo, with significant dose-dependent, anti-tumor activity in four different human tumor types including colon, pancreatic, lung, and ovarian. This activity was cytostatic in nature and was maintained if dosing was continued. That is, tumor growth is suspended while the drug is administered but returns to baseline rates when the agent is withdrawn. Therefore, the optimal schedule will be an uninterrupted one. To assess the activity of sorafenib in a timely manner and with a meaningful interpretation, a randomized discontinuation design was adopted in the present trial, conducted in a population who were potentially sensitive to sorafenib. PURPOSE: This randomized phase II trial is studying sorafenib to see how well it works compared to placebo in treating patients with refractory non-small cell lung cancer.
NCT03118570

NCT05623839
The main purpose of this study is to learn about the safety and tolerability of LY3305677 when given to participants with obesity or overweight. Blood tests will be performed to investigate how the body processes the study drug and how the study drug affects the body. Each enrolled participant will receive injections of LY3305677 or placebo given just under the skin. For each participant, the study will last about approximately 28 weeks.
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.
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.
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.
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.
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.
NCT04173026
The Dissemination and Implementation of Stroke Prevention Looking at the Care Environment (DISPLACE) study is a multi-center, national, National Heart, Lung and Blood Institute (NHLBI)-funded grant to look at the real-world implementation of stroke prevention guidelines (STOP Protocol) in which transcranial Doppler (TCD), a measure of cerebral blood vessel velocity, is used to screen for stroke risk in children ages 2-16 with sickle cell anemia (SCA). Part 3 of the DISPLACE study is an implementation clinical trial designed to test novel implementation strategies with the goal of improving adherence and implementation of stroke screening. 16 of the lowest scoring implementation rates from DISPLACE Part 1 will participate in DISPLACE Part 3. All original 28 sites from DISPLACE Parts 1 and 2 will receive a patient and provider educational intervention including a re-branding of the TCD as "Sickle Stroke Screen" with a new infographic and educational materials. The 16 sites with moving to Part 3 will be provided a Provider reminder strategy, which is a web based application designed to remind providers of when patients are due for their Sickle Stroke Screen. These 16 sites will be randomized and 8 will be given an additional Patient Communication Strategy. These sites will have a single designed coordinator with whom patients will communicate with about scheduling, rescheduling, and any other questions regarding their Sickle Stroke Screen. Upon completion, data will be analyzed to compare those who have had TCD screenings done appropriately and those who did not as well as the overall effect of the multi level interventions on the changes in TCD rates.
NCT03118674
In the medical literature there case reports that Harvoni improves symptoms in patients with PCT. However, this has never been systematically tested. Therefore, the purpose of this study is to assess whether Harvoni alone is an effective therapy of active PCT in patients with Chronic Hepatitis C.
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.
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.
