The primary objective of this study is to conduct a proof of concept pilot study that will provide a preliminary evaluation of the safety of plerixafor alone or in combination with bortezomib on plasma cell mobilization, Human Leukocyte Antigen (HLA) antibody levels and toxicity profile in sensitized patients awaiting kidney transplantation.
The secondary objective of this study is to conduct additional analyses of the study regimen on HLA antibody levels using multiple different assays and statistical analysis.

This study will determine whether Ataciguat (HMR1766) is well-tolerated in patients with mild to moderate calcific aortic valve stenosis. The primary focus of these studies will be on changes in blood pressure and orthostatic tolerance (i.e., ability to stand up without passing out), and determining whether treatment with Ataciguat results in significant reductions in blood pressure in this patient population.
