NCT01070394
The purpose of this study is to examine the effectiveness and length of effect of Vyvanse on lessening Attention-Deficit/Hyperactivity Disorder symptoms in adults. The study will also investigate the safety and tolerability of Vyvanse in adults with ADHD.

Mortality in the major thrombotic microangiopathies (TMAs), TTP and aHUS, exceeds 90% unless rapidly diagnosed and appropriately treated. TMAs complicate 10-20% of allogeneic bone marrow hematopoietic stem cell transplants (alloHSCT), conveying inferior survival. Multiple etiologies have been proposed for these transplant-associated TMAs (TA-TMAs), but once infection, graft vs. host disease (GvHD), and drug effects have been ruled out, most are treated as TTP-like disorders using plasma exchange (PEx). But PEx has no impact on mortality in this setting. Clear definition of the pathophysiology of the TA-TMAs is required to guide effective treatment. Investigators hypothesize that an aHUS-type TMA, related to dysregulation of the alternative complement pathway, is involved and will be characterized by elevated plasma levels of C5b-9 and detectable C5b-9 deposition in bone marrow sinusoidal vessels. Investigators further hypothesize that treatment with inhibitors of terminal complement components will reverse the TMA in vivo, and block endothelial cell damage in our in vitro model systems. The data investigators generate from this observational study of TA-TMAs should enable prediction of their development prior to overt clinical manifestations, and guide appropriate therapy.
NCT01397825
This is a single-arm, open-label, multicenter, dose escalation, phase 1-2 study of alisertib (MLN8237) administered in patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL)/transformed follicular lymphoma (TFL) treated with rituximab and vincristine. The study has three parts as follows: Phase 1, Part 1: Safety lead-in cohort to evaluate alisertib (MLN8237) and rituximab. Phase 1, Part 2: Dose escalation cohort to evaluate alisertib (MLN8237) + Rituximab + Vincristine and determine Phase 2 dose. Patients with other types of B-cell lymphoma (including mantle cell or Burkitt's lymphoma may enroll in Parts 1 and 2. Phase 2: Alisertib (MLN8237) + Rituximab + Vincristine in patients with relapsed or refractory DLBCL or TFL at recommended Phase 2 dose. Note that in 2013 Sponsor decision was taken to not initiate the phase 2 portion of the trial, which would have investigated the triplet at the recommended phase 2 dose identified in part 2. This decision was based on reprioritization within the company and not on any clinical or safety outcomes observed.
