Abstract

BACKGROUND:

Satraplatin is an oral platinum analog with demonstrated activity in a range of malignancies. The current study was designed to evaluate the effect of varying degrees of renal impairment on the safety and pharmacokinetics (PKs) of satraplatin.

PATIENTS AND METHODS:

Patients with advanced solid tumors, refractory to standard therapies, were eligible. The study included four cohorts of patients with varying levels of renal function, and eight patients per cohort: Group 1 (G1) = normal renal function; G2 = mild renal impairment [creatinine clearance (CrCl) 50-80 ml/min]; G3 = moderate impairment (CrCl 30 to <50 ml/min); G4 = severe impairment (CrCl <30 ml/min). Satraplatin was administered orally at 80 mg/m(2)/day on days 1-5 every 35 days.

RESULTS:

A total of 32 patients were enrolled, 8 patients in each renal function group. Each group tolerated the dose of 80 mg/m(2)/day on days 1-5 every 35 days without the need for dose deescalation. The most common adverse events were fatigue (63%), nausea (56%), diarrhea (53%), anorexia (47%), constipation (38%), vomiting (28%), anemia, dyspnea, and thrombocytopenia (25%). There were no dose-limiting toxic effects in any study group. There was increased exposure to plasma platinum and plasma ultrafiltrate platinum in patients with moderate to severe renal impairment.

CONCLUSIONS:

Satraplatin PKs was altered in patients with renal impairment. However, a corresponding increase in satraplatin-related toxic effects was not observed.
