NCT01246011
Heparin/Platelet Factor 4 (PF4) antibody testing will be performed in subjects who have just undergone coronary artery bypass grafting (CABG) surgery. 30 subjects with a positive antibody result and no signs or symptoms of Heparin Induced Thrombocytopenia (HIT) will be randomized to receive argatroban and warfarin. 30 subjects with a positive antibody result and no signs or symptoms of HIT will be randomized to receive no treatment. 30 subjects with a negative antibody result will also be followed in the study. All subjects will have a cardiac CT scan at about 30 days post surgery to measure the patency of their coronary artery bypass vein grafts. This study will evaluate if treating patients who have heparin PF4 antibodies post-CABG with argatroban and warfarin has any effect on the short-term patency of coronary artery bypass vein grafts.
NCT01767454
This is an open-label, multi-center, dose-finding Phase 1 study that will enroll subjects at least 18 years old with unresectable or metastatic melanoma and BRAF V600 mutations. The primary objective of the study is to describe the safety for the doublet therapy (dabrafenib and ipilimumab) and the triplet therapy (dabrafenib/trametinib and ipilimumab). Preliminary efficacy data will also be collected. Subjects will be assigned to receive either the doublet combination (dabrafenib and ipilimumab) or the triplet combination (dabrafenib, trametinib, and ipilimumab). Subjects will be enrolled to dose-finding cohorts in the doublet combination (dabrafenib + ipilimumab) in a sequential 3+3 fashion. Following establishment of a dose for the doublet combination, an expansion cohort will be opened. At the same time, enrollment to dose finding cohorts for the triplet combination (dabrafenib + trametinib + ipilimumab) will begin in a sequential 6+6 fashion. Enrollment into triplet cohorts will take priority when both the doublet expansion arm and the triplet dose-finding arm are open for enrollment at the same time. Approximately 9-24 subjects will be enrolled to the dose finding portion of the study. Approximately 30 subjects will be enrolled to doublet expansion cohort and 30 subjects will be enrolled in the triplet expansion cohort. A two-week run-in period without ipilimumab will be followed by 4 intravenous doses of ipilimumab at the recommended dose and schedule. Oral daily dosing of dabrafenib or dabrafenib + trametinib will continue from the two-week run-in, through combination with ipilimumab, and post-ipilimumab until no longer of clinical benefit, in the opinion of the treating physician, or until unacceptable AE or death
