NCT00267371

NCT01423058
The myeloproliferative neoplasms (MPN), most notably polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF) are a diverse but inter-related suite of clonal disorders of pluripotent hematopoietic stem cells (Tefferi et al., 2008). The MPN share a range of biological, pathological, and clinical features including the relative overproduction of one or more cells of myeloid origin, growth factor independent colony formation in vitro, marrow hypercellularity, extramedullary hematopoiesis, spleno- and hepatomegaly, and thrombotic and/or hemorrhagic diatheses (Tefferi et al., 2005). This is a multi-centre, open-label, non-randomized, dose-escalation study, to be conducted in two phases: a dose-escalation phase (Part 1), to determine the safety and tolerability of momelotinib (CYT387), and to identify a therapeutic dose for the expanded cohort; and a dose-confirmation phase (Part 2), which will be a cohort expansion at or below the MTD of momelotinib. In the Part I dose-escalation phase of the study, subjects will be assigned to dose levels in successive cohorts starting with a dose in the first cohort of 200 mg BID (twice daily with doses taken approximately 12 hours apart). Doses will be escalated by 50 mg BID per cohort until dose-limiting toxicities are observed. The dose level at which ≥2 of 6 subjects develop a first cycle dose-limiting toxicity (DLT) is defined as the DLT level. The maximum tolerated dose (MTD) is defined as the dose level below the DLT level. New dose levels may begin accrual only if all subjects at the current dose level have been observed for a minimum of 28 days from the first day of treatment. The dose level chosen for study in the dose confirmation phase of the study will be the MTD or a lower dose shown to have significant clinical activity (efficacy) as determined by the safety review committee. Subjects will be evaluated weekly for the first cycle, every 2 weeks during cycle 2, then monthly for 4 cycles for a total of 6 cycles. In the dose-confirmation phase of the study, approximately fifty (50) subjects will be treated at the MTD or at a lower dose shown to have significant clinical activity (efficacy) as chosen by the Safety Review Committee. In the dose confirmation phase of the study subjects will be evaluated every 2 weeks during the first treatment cycle, and then monthly for 5 cycles for a total of 6 cycles.
NCT02445976
The goal of this clinical study is to determine the efficacy and safety of Seviteronel, a lyase-selective inhibitor of CYP17 and an androgen receptor antagonist, in patients with castration-resistant prostate cancer (CRPC) who have been previously treated with enzalutamide and/or abiraterone.
NCT01786993
This IDE study is a prospective, randomized, double-blind, multi-center clinical study to evaluate the safety and efficacy of patient treatment with MPP compared to patient treatment with standard BiV pacing at 9 months. The study will be conducted at a maximum of 50 investigational centers located in the United States. A maximum of 506 subjects implanted with the Quadripolar cardiac resynchronization therapy device (CRT-D) system will be enrolled in the study.
NCT01236794
The purpose of this study is to examine the effects of a lifestyle intervention program on type 2 diabetes risk factors and quality of life in overweight Latino youth.
NCT01993862
The purpose of this study is to determine whether it is safe to send patients home from the hospital on the same day following an implantable cardioverter defibrillator (ICD) implant.
NCT02470312
The goal of this registry/observational study is to collect data on the clinical utility of MediGuide™ system in cardiac resynchronization therapy (CRT) implantation and electrophysiology (EP) procedures.
NCT02548455
The primary intent of this study is to assess the safety of the model 1457Q Quartet LV lead at 3 months in a patient population indicated for cardiac resynchronization therapy.
NCT01628549
To evaluate the safety and effectiveness of 3 strengths of P005672-HCl compared to placebo for the treatment of moderate to severe facial acne vulgaris.
NCT03826550
Therapeutic Equivalence of Diclofenac Sodium Gel 3% and Solaraze ®, in the treatment of Actinic Keratosis
NCT02012920
The goal of this clinical study is to determine the safety, tolerability, pharmacokinetics and activity of Seviteronel, a lyase-selective inhibitor of CYP17, in patients with castration-resistant prostate cancer (CRPC).
NCT00636987
The purpose of this study is to further evaluate the long-term safety and effectiveness of the Biocor and Biocor Supra Valves.
NCT02258607
This study is conducted in two phases. The Dose-finding Lead-in Phase, Part A, will evaluate the safety and determine the maximum tolerated dose (MTD) of momelotinib (MMB) when combined with trametinib. Once the MTD of momelotinib (MMB) is determined, the study will proceed to the Dose-finding Lead-in Phase, Part B, to determine the MTD of trametinib. After the MTD is established, the study may proceed to an expansion phase to determine the efficacy, safety, and tolerability of MMB combined with trametinib at the MTD in participants with kirsten rat sarcoma viral oncogene homolog (KRAS) mutated metastatic non-small cell lung cancer (NSCLC). Each treatment cycle will consist of 28 days and treatment will continue in the absence of disease progression, unacceptable toxicity, consent withdrawal, or participant's refusal of treatment.
NCT02418819
This study is designed to investigate the safety, tolerability pharmacokinetics and pharmacodynamic effects of PF-06412562 following multiple dose administration as MR tablets in subjects with schizophrenia.
NCT01207726
This study combines the deoxyribonucleic acid (DNA) methyltransferase inhibitor, 5-azacitidine (5-AZA), with an orally bioavailable histone deacetylase inhibitor, entinostat (SNDX-275), for the adjuvant treatment of patients with resected stage I non-small cell lung cancer (NCSLC).
NCT02580448
The goal of this clinical study is to determine the safety, pharmacokinetics, pharmacodynamics and efficacy and activity of seviteronel, a lyase-selective inhibitor of CYP17, in patients with advanced breast cancer.
NCT00135694
In order to prevent organ rejection, patients receiving liver transplants currently require life-long treatment with immune system-suppressing medications to prevent the rejection of the transplanted liver. However, these medications can cause long-term side effects, such as infection, kidney problems, diabetes, and cancer. In patients infected with hepatitis C virus (HCV), these medications may increase the risk of HCV infection in the transplanted liver. The purpose of this study is to determine whether a slow withdrawal of immune system-suppressing medications is safe in two groups of subjects: those who receive a liver transplant due to HCV, and those who receive a liver transplant due to non-immune, non-viral causes of liver failure. The study will also look at whether slow withdrawal will help reduce the long-term side effects of immune system-suppressing medications and decrease the chance for HCV infection of the new liver in transplant patients with HCV.
NCT00300235
Priapism, a prolonged erection of the penis, is a medical issue that often affects men with sickle cell disease. The purpose of this study is to collect demographic and clinical information on priapism by interviewing men with sickle cell disease.
NCT02216409
The purpose of this study is to assess the safety and tolerability of Hu5F9-G4 in participants with solid tumors.
NCT00068237
RATIONALE: Moving a salivary gland out of the area that will undergo radiation therapy may protect the gland from side effects of radiation therapy and may prevent xerostomia (dry mouth). PURPOSE: Phase II trial to study the effectiveness of salivary gland surgery in preventing xerostomia in patients who are undergoing radiation therapy for head and neck cancer.
