We
previously determined the maximal tolerated dose of weekly CPT-11 with fixed
dose BCNU as 225 mg/m2 for malignant glioma patients on concurrent
glucouronidation-enhancing anticonvulsants (GEAC) (dilantin, phenobarbitol and
tegretol) and 125 mg/m2 for those not on GEACs.
We now present preliminary
results of a phase II study for malignant glioma patients given 100 mg/m2 of
BCNU every 6 weeks on the same day as the first CPT-11 dose.
CPT-11 is
administered intravenously weekly at 225 mg/m2/dose for patients on GEACs, and
125 mg/m2/dose those not on GEACs.
Patients received BCNU plus 4 weekly doses of
CPT-11 followed by a 2 week rest.
Among thirty-nine patients with recurrent
tumors (glioblastoma multiforme (GBM), n=28; anaplastic astrocytoma (AA), n=9;
anaplastic oligodendroglioma, n=2) 1 patient had a partial response (PR), 17 had
stable disease (SD), 15 had progressive disease (PD) and 6 are too early (TE).
Toxicity grade 3 included hematologic (n=6), infection (n=6), diarrhea (n=5) and
thrombosis (n=1).
Twenty newly diagnosed patients have been treated (GBM, n=14;
AA, n=6).
One had a CR, 2 had a PR, 4 had SD, 8 had PD and 5 are TE.
Toxicity ³ grade 3 among newly diagnosed patients included
diarrhea (n=6), hematologic (n=3), infection (n=3), thrombosis (n=4) and
pulmonary (n=2).
Four of 48 evaluable patients (8%) achieved a PR or CR; 21/48
(44%) achieved SD for 2 or more cycles.
These results indicate that BCNU plus
CPT-11 is a promising regimen for patients with malignant glial tumors.
