Phase 1 and pharmacokinetic study of intravenous irinotecan in refractory solid tumor patients with hepatic dysfunction.

Purpose: To determine the recommended starting doses and pharmacokinetics of irinotecan in cancer patients with impaired liver function treated on a weekly schedule.

Experimental Design: Patients with solid tumors who had impaired liver function were enrolled into four groups based on baseline serum total bilirubin and aspartate aminotransferase (AST)/alanine aminotransferase (ALT): Group 1 (n = 19): total bilirubin 1.5 to 3.

Optimisation of irinotecan dose in the treatment of patients with metastatic colorectal cancer after 5-FU failure: results from a multinational, randomised phase II study.

Although irinotecan 350 mg m(-2) is a standard option for relapsed/refractory advanced colorectal cancer, there is some evidence that suggests that a higher dose may be more effective, with acceptable tolerability, following 5-fluorouracil (5-FU). This study assessed the optimal dosing strategy for irinotecan, along with treatment efficacy and safety. A total of 164 patients with metastatic colorectal cancer progressing after failure on 5-FU or raltitrexed received either 350 mg m(-2) irinotecan (Group A; n=36) or 250, 350 or 500 mg m(-2), according to individual patient tolerance (Group B; n=62) or based on risk factor optimisation (Group C; n=66).

A randomised phase II multicentre trial of irinotecan (CPT-11) using four different schedules in patients with metastatic colorectal cancer.

The purpose of this phase II trial was to compare the efficacy, safety and pharmacokinetics of four irinotecan schedules for the treatment of metastatic colorectal cancer. In total, 174 5-fluorouracil pretreated patients were randomised to: arm A (n=41), 350 mg m(-2) irinotecan as a 90-min i.v.

Irinotecan plus gemcitabine results in no survival advantage compared with gemcitabine monotherapy in patients with locally advanced or metastatic pancreatic cancer despite increased tumor response rate.

Purpose: This phase III, randomized, open-label, multicenter study compared the overall survival associated with irinotecan plus gemcitabine (IRINOGEM) versus gemcitabine monotherapy (GEM) in patients with chemotherapy-naive, locally advanced or metastatic pancreatic cancer.

Patients And Methods: IRINOGEM patients received starting doses of gemcitabine 1,000 mg/m2 and irinotecan 100 mg/m2 given weekly for 2 weeks every 3-week cycle. GEM patients received gemcitabine 1,000 mg/m2 weekly for 7 of 8 weeks (induction) and then weekly for 3 of 4 weeks.

Continuous infusion of hepatic arterial irinotecan in pretreated patients with colorectal cancer metastatic to the liver.

Background: Irinotecan is an active drug in colorectal cancer. In patients with liver metastases, hepatic arterial infusion of irinotecan could theoretically result in higher exposure to the drug. In order to determine the efficacy of hepatic arterial irinotecan we conducted a phase II study in pretreated patients with liver metastases of colorectal cancer.

Continuous administration of irinotecan by hepatic arterial infusion: a phase I and pharmacokinetic study.

Purpose: The main advantage of administering chemotherapy by means of hepatic arterial infusion (HAI) is the achievement of a high concentration of the drug in the liver. Irinotecan (CPT-11) is an active agent for the treatment of advanced colorectal cancer and other tumor types, which frequently metastasize in the liver. We performed a Phase I and pharmacokinetic study to investigate CPT-11 by hepatic arterial administration in patients with liver metastases.

Irinotecan plus fluorouracil/leucovorin for metastatic colorectal cancer: a new survival standard.

Background: Irinotecan is a topoisomerase I inhibitor that prolongs survival in patients with colorectal cancer refractory to fluorouracil (5-FU) and leucovorin (LV). This demonstrated activity of irinotecan as effective second-line therapy for colorectal cancer led to evaluation of combination irinotecan/5-FU/LV as first-line therapy for patients with metastatic disease. The results of two prospective phase III randomized, controlled, multicenter, multinational clinical trials in patients with previously untreated metastatic colorectal cancer served as the basis for U.

Phase I study of irinotecan and raltitrexed in patients with advanced gastrointestinal tract adenocarcinoma.

To determine the dose-limiting toxicities (DLT) and maximum tolerated dose (MTD) of irinotecan and raltitrexed given as sequential short infusions every 3 weeks, 33 patients with pretreated gastrointestinal adenocarcinoma (31 colorectal, 2 oesophagogastric) entered this open label dose-escalation study. For the first five dose levels patients received irinotecan 175-350 mg m(-2) followed by raltitrexed 2.6 mg m(-2).

Irinotecan combined with fluorouracil compared with fluorouracil alone as first-line treatment for metastatic colorectal cancer: a multicentre randomised trial.

Background: Irinotecan is active against colorectal cancer in patients whose disease is refractory to fluorouracil. We investigated the efficacy of these two agents combined for first-line treatment of metastatic colorectal cancer.

Methods: 387 patients previously untreated with chemotherapy (other than adjuvant) for advanced colorectal cancer were randomly assigned open-label irinotecan plus fluorouracil and calcium folinate (irinotecan group, n=199) or fluorouracil and calcium folinate alone (no-irinotecan group, n=188).

Phase I and pharmacokinetic study of irinotecan administered as a low-dose, continuous intravenous infusion over 14 days in patients with malignant solid tumors.

Purpose: To evaluate the feasibility of administering irinotecan as a continuous intravenous infusion for 14 to 21 days.

Patients And Methods: Patients with solid tumors refractory to standard therapy received continuous infusions of irinotecan by means of an ambulatory infusion pump. The starting dosage was 12.

Long-term survival of patients with unresectable colorectal cancer liver metastases following infusional chemotherapy with 5-fluorouracil, leucovorin, oxaliplatin and surgery.

Context: Long-term survival of patients with metastatic colorectal cancer has been achieved only in patients who underwent complete resection of metastases. Such surgery could be performed in a greater proportion of patients if effective chemotherapy could downstage previously unresectable metastases. This approach has been limited by the low tumor response rate achieved with conventional chemotherapy.

Dose-finding study of docetaxel and doxorubicin in first-line treatment of patients with metastatic breast cancer.

Purpose: To determine the maximum tolerated dose (MTD), the dose-limiting toxicity (DLT) and the recommended dose of docetaxel in combination with doxorubicin, and to evaluate the activity in patients with advanced breast cancer.

Patients And Methods: Forty-two women with untreated metastatic breast cancer (79% with visceral metastases; 52% with prior adjuvant anthracycline therapy) were treated with doxorubicin (40-60 mg/m2) i.v.

Treatment with a nonanthracycline regimen in advanced breast cancer: vinorelbine, cyclophosphamide, and 5-fluorouracil with folinic acid.

The efficacy of combination therapy with vinorelbine, cyclophosphamide, and 5-fluorouracil was assessed in women who had received no prior therapy for locally advanced or metastatic breast cancer. Sixty patients with metastatic breast cancer who had finished any adjuvant therapy at least 6 months previously and who had not received treatment for advanced disease were entered onto the study. The schedule consisted of vinorelbine (Navelbine, Pierre Fabre Medicament) 25 mg/m2 on days 1 and 8, cyclophosphamide 500 mg/m2 on day 1, and 5-fluorouracil 500 mg/m2 followed by folinic acid 200 mg/m2 on days 1 and 8.

A phase II study of irinotecan alternated with five days bolus of 5-fluorouracil and leucovorin in first-line chemotherapy of metastatic colorectal cancer.

Purpose: This multicenter phase II study was designed to assess the efficacy of the alternating schedule of irinotecan (CPT-11) with bolus 5-fluorouracil (5-FU) and leucovorin (LV) in first-line chemotherapy for metastatic colorectal cancer (CRC).

Patients And Methods: Patients with histologically proven metastatic colorectal cancer, and at least one bidimensionally measurable lesion, aged 18-70, with performance status < or = 2, normal baseline biological values and no prior chemotherapy (or only adjuvant chemotherapy completed > or = 6 months before study entry) were selected. Treatment was irinotecan 350 mg/m2, i.
