AD-32 (N-trifluoroacetyladriamycin-14-valerate), an analogue of doxoru
bicin, was examined for intraperitoneal (ip) administration in a phase
2 trial involving 25 patients with advanced gynecologic malignancies.
At an AD-32 dose of 600 mg/m(2), the limiting toxicity was grade 4 ne
utropenia (64% of patients), while severe abdominal pain was relativel
y uncommon (12%). Intraperitoneal AD-32 administration was associated
with a 200-fold pharmacokinetic advantage for cavity exposure, compare
d to the systemic compartment. At the 600 mg/m(2) dose level, 4 of 9 p
atients (44%) with ascites experienced control of malignant fluid reac
cumulation. Based on the results of this phase 1 trial, further explor
ation of a possible role for the ip administration of AD-32 in individ
uals with gynecological malignancies appears indicated, particularly i
n patients with either small volume residual disease after initial sys
temic chemotherapy or in those with intractable ascites. (C) 1996 Acad
