camptothecin/fatigue

OBJECTIVE CT-2106 is a 20(S)-camptothecin poly-L-glutamate conjugate. This linkage stabilizes the active lactone form of camptothecin and enhances aqueous solubility. In addition, poly-L-glutamate is postulated to increase tumor delivery of the active compound through enhanced permeability and

OBJECTIVE This Phase II study was conducted to determine the efficacy and toxicity of 9-nitro-camptothecin (9-NC) in patients with previously treated metastatic breast cancer. Pharmacokinetic samples were obtained to investigate the correlation of plasma 9-NC exposure with clinical response and

OBJECTIVE In vitro studies have suggested that 9-nitro-20(s)-Camptothecin (9NC/Orathecin/Rubitecan) can enhance the effects of radiation. We conducted a phase I study to assess the toxicity and determine the maximum tolerated dose of 9NC when combined with radiation in patients with locally advanced

GI1147211 is a 7-substituted 10,11-ethylenedioxy-20(S)-camptothecin analogue that inhibits the nuclear enzyme topoisomerase I. In this Phase I and pharmacological study, 24 patients with advanced solid malignancies received a total of 72 courses of GI147211 as a 30-min infusion daily for 5

OBJECTIVE Although preclinical studies on camptothecin antitumor effect have demonstrated the superiority of low-dose protracted dosing, these findings were not replicated in the clinic. 7-t-butyldimethylsilyl-10-hydroxycamptothecin (AR-67) is a camptothecin analogue currently under investigation in

OBJECTIVE Diflomotecan (BN80915) is an E-ring modified camptothecin analogue that possesses greater lactone stability in plasma compared with other topoisomerase I inhibitors, a potential advantage for antitumor activity. As with other camptothecins, oral administration has pharmacological and

OBJECTIVE The purpose of this trial was to assess the objective clinical response, toxicity, and time to progression of treatment with 9-Nitro-Camptothecin (9-NC) in patients with advanced chordoma, soft tissue sarcoma (STS), and gastrointestinal stromal tumor (GIST). METHODS Patients with locally

OBJECTIVE To determine the maximal tolerated dose and dose-limiting toxicities (DLT) of pegamotecan (polyethylene glycol-camptothecin) in patients with advanced malignancies when administered in cycles of once weekly for 3 of 4 weeks. METHODS Eligible patients had advanced solid tumors that failed

OBJECTIVE The purpose is to evaluate the feasibility and safety of aerosol administration of the topoisomerase I inhibitor, 9-nitrocamptothecin, in a liposome formulation, and to recommend a dosage for a Phase II trial for an 8-week daily treatment schedule. METHODS Patients with primary or

OBJECTIVE Combination chemotherapy results in a significant survival advantage in patients with advanced gastric cancer compared to best supportive care. Nevertheless, the prognosis remains poor with a median survival of 8-10 months. Topoisomerase-I inhibitors such as irinotecan have activity in

OBJECTIVE To determine the maximum-tolerated dose (MTD), dose-limiting toxicity (DLT), pharmacokinetic (PK) profile, and recommended phase II dose of Exatecan mesylate (DX-8951f) when administered as a 24-hour continuous infusion every 3 weeks to patients with solid tumors. METHODS Twenty-two

Patients with advanced solid malignancies were enrolled to an open-label, single-arm, dose-escalation study, in which CRLX101 was administered intravenously over 60 min among two dosing schedules, initially weekly at 6, 12, and 18 mg/m(2) and later bi-weekly at 12, 15, and 18 mg/m(2). The maximum

OBJECTIVE A phase II trial of the novel camptothecin karenitecin (BNP1350) was conducted to determine its efficacy and tolerability in patients with metastatic melanoma. Patients were biopsied to determine topoisomerase expression at baseline and response to therapy. METHODS Eligible patients had

OBJECTIVE Combination chemotherapy with third-generation, nonplatinum agents (ie, gemcitabine, vinorelbine, taxanes, or camptothecins) represents a well-tolerated frontline treatment option for metastatic non-small-cell lung cancer and might play a role as salvage therapy as well. The aim of this

OBJECTIVE Based on preclinical data that demonstrated synergy between alkylating agents and topoisomerase (topo) I poisons, we determined the maximum-tolerated dose (MTD) of topotecan, using a 5 day bolus schedule, that could be given in combination with a single, fixed dose of cyclophosphamide.
