Flavone acetic acid is the second in a series of compounds based on the flavonoid aglycone ring structure to be clinically evaluated in malignant disease. Preclinical studies have indicated that a minimum plasma level of 150 micrograms/ml is required before therapeutic efficacy (in a wide range of experimental tumors) is seen in mice; both in vitro and in(More)
PURPOSE The DNA methyltransferase inhibitor 5-aza-2'-deoxycytidine (decitabine) induces DNA demethylation and re-expression of epigenetically silenced genes, and increases carboplatin sensitivity of tumor xenograft models. We designed a clinical study to determine the feasibility of delivering a dose of decitabine, combined with carboplatin, that would be(More)
We investigated the differences in plasma protein binding of flavone acetic acid (FAA) in mice and men in an attempt to explain the inter-species differences in response. In vitro data indicate both qualitative and quantitative differences in FAA protein binding: approximately 80% is bound in humans, with two different types of binding site identified; in(More)
N-Debenzoyl-N-tert-butoxycarbonyl-10-deacytyl taxol (Taxotere, RP 56976) is a semisynthetic analogue of taxol, prepared from a noncytotoxic precursor extracted from the needles of the European yew tree (Taxus baccata L.). It has a broad spectrum of antitumor activity against a variety of transplantable tumors in mice. In vitro cytotoxicity assays suggest(More)
Flavone acetic acid pharmacokinetics were studied in 31 patients in a phase I clinical trial. The drug was given by i.v. infusions over 1, 1.5, 3, and 6 h at doses ranging from 0.5 to 6.4 g/m2. The pharmacokinetic parameters were determined according to a nonlinear model including Michaelis-Menten-type kinetics. The mean elimination half-life is 4.8 h and(More)
Rhizoxin is a tubulin-binding cytotoxic compound, isolated from the fungus Rhizopus chinensis, with significant antineoplastic activity in several murine and human tumor models. In this Phase I study, the drug was administered by i.v. bolus injection at 3-wk intervals. Twenty-four patients with refractory solid tumors were treated; 60 courses of rhizoxin(More)
We have conducted a Phase I and initial clinical pharmacological evaluation of LM985, the first of a series of compounds based on the flavone ring structure to be considered for clinical trial in malignant disease. The drug was administered i.v. to 26 patients with advanced cancer on an every-21-day schedule. Patients were treated at 14 dosage levels(More)
EO9 is a synthetic indoloquinone which was designed to undergo redox cycling and formation of alkylating intermediates under bioreductive conditions. As part of a phase I clinical trial, EO9 plasma disposition was evaluated in 20 patients receiving 2.7-15 mg/m2i.v. weekly for 3 weeks. Pharmacokinetic studies were performed with the first and third dose of(More)
Recent clinical trials have suggested that a combination of folinic acid and 5-fluorouracil (5-FU) may improve response rates and survival in patients with advanced colorectal cancer. However, this regimen has been complicated by potentially life threatening toxicity. Regional delivery of folinic acid via a hepatic artery catheter might be expected to(More)
BACKGROUND Rhizoxin is a new macrocyclic lactone isolated from the fungus Rhizopus chinensis which displays broad-spectrum antitumor activity against murine and human tumor xenografts and has activity against a number of vincristine-resistant tumors in vitro and in vivo. PURPOSE This study describes the preclinical and clinical pharmacology of rhizoxin to(More)
