A phase I study of cis-diammine(glycolato)platinum (254-S; NSC 375101D) was conducted in 15 patients with refractory or relapsing malignancy by 5-day continuous i.v. infusion. Three to 5 patients per dose were given 50, 75, 87.5, or 100 mg/m2/120 h (10-20 mg/m2 daily for 5 days). Toxicity evaluation and pharmacokinetic analysis were performed in 15 and 14 patients, respectively. Thrombocytopenia and neutropenia were the dose-limiting toxicities at the maximum tolerated dose of 87.5 mg/m2/120 h (17.5 mg/m2/day); however, nonhematological toxicities including renal toxicity, nausea and vomiting, and peripheral neuropathy were mild and well tolerated. The nadir of platelets and neutrophils was observed 4 and 5 weeks, respectively, after the initiation of drug infusion. Plasma and urine samples were obtained during and after infusion for quantification by atomic absorption spectrophotometry of total and free platinum levels derived from 254-S. The maximum level of total platinum was obtained after 120 h of infusion, whereas the steady state concentration of free platinum in the patients given 75 mg/m2 or more was over 0.1 microgram/ml. Free platinum levels declined monophasically, with half-lives of 0.65-2.56 h/100 mg/m2 dose. The mean area under the concentration versus time curve (AUC) in the patients treated with 75 mg/m2 was 1069 micrograms/ml, which was similar to that obtained in the patients receiving 100 mg/m2 of 254-S by i.v. drip infusion over 30 min. There was a direct correlation between the dose administered and the AUC of platinum (R = 0.757, P = 0.002) or the steady state plasma concentration of free platinum (R = 0.763, P = 0.002). The percentage of platinum excreted in urine 144 h after the initiation of infusion ranged from 73.1 to 100% for each dose level. No significant relationship was established between creatinine clearance in patients before treatment and the AUC or steady state concentration of free platinum. The plasma platinum AUC showed a linear correlation with the percentage of change in leukocytes [formula: see text] (R = 0.736, P = 0.003). In conclusion, the recommended phase II dose for a continuous infusion of 254-S is 75.5 mg/m2/120 h every 6 hours.
