The clinical kinetics of 1,4-dihydroxy-5,8-bis[[2-[(2-hydroxyethyl)amino]ethyl]amino]-9,10-anthra cenedione dihydrochloride (DHAQ) are reported. DHAQ, 1 to 3 mg/m2, was administered as an intravenous bolus to six patients with metastatic cancer. Plasma clearance of the drug followed a biphasic pattern with a harmonic mean initial half-life (t 1 2) of 13.7 min and a terminal t 1 2 of 37.4 hr. Recovery of unchanged drug in the urine was 6.8% at 24 hr and 7.3% at 72 hr, while the corresponding recovery of total radioactivity was 9.4% and 11.3%. Apparent volume of distribution of DHAQ was about 13.8 ± 2.9 11kg. Total clearance was 238.7 ml/kg/hr, twice the creatinine clearance.
