NCT03939312
The purpose of this study is to evaluate the safety and tolerability of atogepant 60 mg once a day for the prevention of migraine in participants with episodic migraine.
NCT03505021
This study will evaluate whether prolonged oral levosimendan can preserve respiratory function more effectively than placebo, resulting in better patient functionality as measured by the ALSFRS-R scale. In this randomized, double-blind, placebo-controlled, parallel-group, multicenter study, subjects are allocated in a 2:1 ratio to receive either levosimendan (1 -2 mg daily) or placebo for 48 weeks. The primary endpoint is slow vital capacity (SVC) at 12 weeks, with the impact on patient function assessed through 48 weeks, adjusted for patient outcome, using ALSFRS-R (combined assessment of function and survival, CAFS). Other important efficacy measures include time to respiratory events, clinical global impression (CGI), assessment of dyspnea using the Borg scale and sleep scales (Pittsburgh sleep quality index and Epworth sleepiness scale). Patient safety is monitored using conventional methods including adverse events, safety laboratory tests, vital signs and 12-lead EKG. Following screening and baseline visits, patients attend the clinic at 2, 4, 8, 12, 24, 36 and 48 weeks, with telephone assessments conducted at weeks 18, 30 and 42. An end of study visit is performed 14-25 days after the last study treatment administration. The study will be monitored by an independent data and safety monitoring board. A long-term extension study will be available for patients completing the study.
NCT02953704
The purpose of this prospective, longitudinal, noninterventional study is to describe clinical characteristics, evolution of disease burden, and treatment patterns in patients with select subcategories of essential thrombocythemia (ET) or myelofibrosis (MF).
NCT04206670

NCT00676663
The purpose of this study is to evaluate the safety and efficacy of entinostat in combination with exemestane in the treatment of advanced breast cancer.
NCT03288129
This study will assess the retention rate of perampanel when given as monotherapy or first adjunctive therapy in participants with partial-onset seizures or primary generalized tonic clonic seizures. The study consists of 4 periods: a Screening Period (to start no earlier than 6 weeks before the first dose of study drug), a Titration Period (up to 13 weeks), a Maintenance Period (39 weeks), and a Follow-Up Period (4 weeks).
NCT02371369
This is a Phase 3 clinical study, which aims to evaluate the effectiveness of an investigational drug called pexidartinib for the treatment of certain tumors for which surgical removal could cause more harm than good. The main purpose of this study is to gather information about the investigational drug pexidartinib, which may help to treat tumors of pigmented villonodular synovitis (PVNS) or giant cell tumor of the tendon sheath (GCT-TS). The study consists of two parts with a follow-up period. In Part 1, eligible study participants will be assigned to receive either pexidartinib or matching placebo for 24 weeks. A number of assessments will be carried out during the course of the study, including physical examinations, blood tests, imaging studies, electrocardiograms, and questionnaires. MRI scans will be used to evaluate the response of the tumors to the treatment. Some subjects, assigned to placebo in Part 1 transitioned to pexidartinib for Part 2. Then a protocol amendment was written to allow only pexidartinib patients to continue into Part 2. Part 2 is a long-term treatment phase in which all participants receive open-label pexidartinib. There was also a follow-up period added to Part 2.
NCT05367050
The quality of recovery after surgery is multi-factorial and includes both physical and mental factors. Persistent pain after surgery is a common problem after major surgery and can result in persistent opioid use. The investigators will be evaluating if the addition of a pain coach/councilor before and after surgery, through a tele health platform (LucidLane) can improve participant's recovery from major joint surgery.
NCT00086528
The primary objective of this study is as follows: * To evaluate the safety and tolerability of XL647 administered orally as a single dose and as repeat doses in subjects with solid tumors. The secondary objectives of this study are as follows: * To evaluate the plasma pharmacokinetics of XL647 administered orally as a single dose and as repeat doses in subjects with solid tumors, * To estimate renal elimination of XL647 administered orally as a single dose in subjects with solid tumors. The exploratory objective of this study is as follows: * To assess the pharmacodynamic effects of XL647 administration in plasma and peripheral blood cells. In addition, subjects may be eligible to enter a Treatment Extension Period. The following information will be obtained from this part of the study: * Long-term safety and tolerability of XL647 after repeat administration, * Tumor response after repeat administration of XL647.
NCT00336765
The purpose of this study is to assess the safety and tolerability of the multiple receptor tyrosine kinase (RTK) inhibitor (including EGFR, VEGFR2, ErbB2, and EphB4) XL647 when given orally daily to adults with advanced solid tumors.
NCT01129687
The investigators study is to investigate safety and efficacy of performing a planned incomplete removal of large acoustic neuroma tumors to decrease surgical morbidity and yet avoid tumor recurrence by post-operative radiation therapy.
NCT02834650
This study will collect MRI from healthy volunteer boys and boys with Duchenne Muscular Dystrophy (DMD) to help researchers identify and validate cardiac MRI biomarkers to better understand the health of the heart and changes in heart health over time in boys with DMD. Currently, there is a lack of sufficiently well characterized cardiac MRI biomarkers that can serve as endpoints for detecting on-target and/or off-target cardiac effects during clinical drug trials for boys with DMD. Consequently, the first objective is to identify and characterize several cardiac MRI biomarkers for boys with DMD.
NCT05011136
This is an observational study using an online survey to solicit information from nephrologists who care for dialysis patients about the time and effort involved in providing care to home dialysis patients.
NCT01090024
To investigate the effectiveness and safety of BI 671800 given in the morning (AM), evening (PM) or twice daily (b.i.d.) compared too placebo as add on therapy to inhaled corticosteroid in symptomatic asthma patients.
NCT00297895
Subjects must be diagnosed with melanoma. All subjects receive sentinel lymphadenectomy. If the subject is sentinel node positive and meets study requirements, the subject is randomized to receive either (1) completion lymphadenectomy (2) observation with nodal ultrasound. Subjects are then followed for 10 years.
NCT04688190

NCT03721705
A Randomized Pivotal Study of RenewTM NCP-5 for the Treatment of Mild Cognitive Impairment due to Alzheimer's Disease or Mild Dementia of the Alzheimer's Type is a pivotal, single blind, parallel design, multi-site study intends to examine the efficacy and safety of RenewTM NCP-5 therapy in the treatment of Cognitive Impairment due to Alzheimer's Disease or Mild Dementia of the Alzheimer's Type. Subjects will be prospectively randomized to treatment or sham (in a 1:1 ratio) using stratification for Cognitive Impairment due to Alzheimer's Disease or Mild Dementia of the Alzheimer's Type, and Cardiovascular Risk (CVR) score at multiple sites. Subjects, ages 55-85, will be consented for 13 months and will receive thirty-five 60-minute RenewTM NCP-5 treatment sessions during a 7-to-12-week initial treatment period, and then transition to a lower frequency maintenance period (twice a week) for a total treatment period of 24 weeks.
