A phase 1/2 study of lenalidomide with low-dose oral cyclophosphamide and low-dose dexamethasone (RdC) in AL amyloidosis.

In this phase 1/2 study, we explored the feasibility and activity of an oral regimen of lenalidomide with low-dose dexamethasone and low-dose oral cyclophosphamide (RdC) in patients with primary systemic light chain amyloidosis. RdC was given for up to 12 cycles in prespecified cohorts at escalated doses: 13 patients were treated in phase 1 and 24 in phase 2; 65% were previously untreated, and most had renal and/or cardiac involvement and elevated cardiac biomarkers. Lenalidomide 15 mg/d and cyclophosphamide 100 mg/d were further evaluated in phase 2.

Pharmacokinetics of teicoplanin in patients undergoing continuous ambulatory peritoneal dialysis.

Objective: To achieve concentrations of teicoplanin in serum and dialysate within the therapeutic range in patients undergoing continuous ambulatory peritoneal dialysis (CAPD).

Design: Pharmacokinetic study.

Setting: A tertiary-care hospital.

Pharmacokinetics of teicoplanin in patients undergoing chronic haemodialysis.

In order to define a dose regimen of teicoplanin for patients undergoing chronic haemodialysis so that they achieved trough drug serum levels above 10 mg/l, two single doses of 5 and 10 mg/kg were administered intravenously in seven anuric patients immediately after the end of haemodialysis. Concentrations of teicoplanin were determined by a microbiological assay in samples collected from peripheral veins via the arterial and the venous lines of the fistulae and from the dialysate during haemodialysis. The administration of a 5 and 10 mg/kg dose gave mean C(max) of 62.
