For each patient, a total of up to 14 blood samples will be collected at the following time points: immediately prior to the first stent implant as time 0, at 10 and 30 minutes, and at 1, 2, 4, 8, 12, 24±6, 48±12, 72±12, 168±36 (7 days), 336±36 (14 days) and 720±36 hours (30 days) after the first BioNIR stent implantation. Whole blood concentration of ridaforolimus will be determined using a validated high performance liquid chromatography mass spectrometry/mass spectrometry (HPLC-MS/MS) method. If two consecutive measurements are available and both demonstrate ridaforolimus levels below the detection limit of the assay, the levels at all subsequent time points will not need to be measured.
