(H.E.L.P.)Apheresis Therapy to Compare the Reduction of LDL (Low Density Lipoprotein) Cholesterol

The primary objective of the study is to demonstrate that the performance of the modified Plasmat® Futura H.E.L.P. Apheresis System is non-inferior to the current FDA approved Plasmat® Secura H.E.L.P Apheresis System for use under the approved indication of the acute reduction of LDL-cholesterol from the plasma in populations for whom diet has been ineffective and maximum drug therapy has either been ineffective or not tolerated.
