Phase II study of MGI-114 administered intravenously for 5 days every 28 days to patients with metastatic colorectal cancer.

We examined the use of MGI-114 (6-hydroxymethyacylfulvene) for the treatment of patients with advanced colorectal carcinoma. Twenty-six patients were enrolled, with a median age of 60 years (range 41-75); 64% were male and all patients had a performance status of 0 or 1. We administered a dose of 11 mg/m2/d x 5 days every 4 weeks. With a median of two cycles (range 0-6) administered, no complete responses or partial responses were observed. Four patients had no change in disease (16%); 15 patients (57%) had progressive disease; seven patients were inevaluable (27%). Toxicity was evaluated in 25 of 26 patients. The main toxicities were hematologic, including granulocytopenia and thrombocytopenia. Neuropsychiatric adverse events included hallucination (7.7%), depression/anxiety (15.4%), and/or insomnia (19.2%). Given the lack of antitumor activity, further study of MGI-114 in colorectal cancer does not appear warranted.

Phase II trial of gemcitabine and docetaxel in patients with advanced carcinoma of the urothelium: a trial of the Eastern Cooperative Oncology Group.

BACKGROUND: Gemcitabine and docetaxel are active agents in advanced urothelial carcinoma. A Phase II trial of this combination was performed to determine the activity and toxicity of these agents in a multiinstitutional setting in patients previously treated with one prior chemotherapy regimen. METHODS: Twenty-nine eligible patients with advanced urothelial carcinoma were treated with docetaxel at a dose of 40 mg/m(2) over 1 hour followed by gemcitabine, 800 mg/m(2), over 30 minutes, both intravenously (i.v.) on Days 1 and 8. Cycles were repeated every 21 days until disease progression or a maximum of 6 cycles. RESULTS: Five patients obtained an objective response for an overall response rate of 17% (90% confidence interval, 7-33%). One patient achieved a complete clinical response. The median overall survival of the group was 7.7 months. Toxicity was moderate with granulocytopenia, anorexia, and fatigue being the most commonly noted side effects. CONCLUSIONS: Gemcitabine and docetaxel is an active second-line combination in patients with advanced urothelial carcinoma. Responses in visceral, lymph node, and soft tissues sites were observed. Granulocytopenia without fever, fatigue, and anorexia was common. Thromboembolic symptoms were reported and are of concern. The combination of gemcitabine and docetaxel has the potential to palliate a subset of previously treated patients with an adequate performance status.
