The activity and toxicity of UFT (Tegafur and Uracil) in a 4:1 molar concentration, plus leucovorin (LV), were evaluated in the treatment of 45 patients with advanced, bidimensionally measurable metastatic colorectal carcinoma. Initially 350 and later 300 mg/m2/day, plus 150 mg LV, as administered in divided doses every 8 h for 28 days. After two courses of treatment, responses were evaluated. The overall response rate was 42.2%, with responses observed in liver (n = 18), lung (n = 6), and bone (n = 1). Five of the 7 patients who received 350 mg/m2 UFT experienced prolonged grade 3 diarrhea, resulting in a dose reduction to 300 mg/m2; 9 patients in the 300-mg/m2 group experienced grade 3 diarrhea, vomiting, abdominal cramping, and fatigue. Minor toxic effects included oral mucositis and rash. The oral regimen of 300 mg/m2/day UFT, plus 150 mg/day LV, administered for 28 days appears to have significant activity against metastatic colorectal carcinoma. The treatment is well tolerated; neutropenia did not occur, and oral mucositis was not significant, even though both are characteristic of intravenous schedules of 5-fluorouracil plus LV. The results of this trial constitutes the basis of phase III clinical trials comparing this oral schedule with intravenous 5-FU and LV to compare clinical efficacy, impact on well-being, and cost. In addition, the current National Surgical Adjuvant Breast and Bowel Project (NSABP) adjuvant colon clinical trial (CO-6) will compare this 28-day schedule of UFT plus oral leucovorin with a weekly regimen of intravenous 5-fluorouracil plus leucovorin in the postoperative adjuvant therapy of Dukes' B and C colon cancer patients.

Recent results demonstrate an emerging role for paclitaxel in patients with urothelial-tract cancer and in patients with testicular cancer. Yielding response rates in the range of 40-50% as a single agent, paclitaxel is one of the most active drugs in metastatic bladder cancer. Ongoing trials of paclitaxel combination chemotherapy with cisplatin or cisplatin and ifosfamide demonstrate substantial objective remission rates above 70% and, in addition, a high range of complete responses. Thus, paclitaxel appears to be an important drug when used as part of first-line combination chemotherapy for metastatic bladder cancer. Ongoing clinical trials focus on the combination of paclitaxel with cisplatin, ifosfamide, gemcytabine, and carboplatin. Furthermore, paclitaxel administration has been demonstrated to be easily applicable to patients with reduced renal function, requiring no dose reduction and producing no increase in toxicity. Future strategies will have to compare the most active paclitaxel combination regimen with first-line MVAC (methotrexate, vinblastine, adriamycin, cisplatin) chemotherapy. Finally, the role of paclitaxel combination regimens needs to be explored in the adjuvant and neoadjuvant setting in patients with bladder cancer. In testicular cancer, paclitaxel has initially been tested in patients with cisplatin-refractory disease. Among 4 consecutive trials involving a total of 83 patients a response rate of 26% has been observed using dose schedules varying from 3-h to 24-h infusions and doses ranging from 175 to 250 mg/m2. The major toxicities of paclitaxel include neutropenia, neurotoxicity, and fatigue syndrome. Currently, combinations of paclitaxel with cisplatin +/- ifosfamide are used as first- or second-line salvage therapy in patients with relapsed metastatic testicular cancer. The German Testicular Cancer Study Group uses a paclitaxel (Taxol, ifosfamide, cisplatin; TIP) combination regimen as salvage treatment. Following the TIP regimen and the application of granulocyte colony-stimulating factor (G-CSF), peripheral blood stem cells (PBSC) are harvested and the patients subsequently receive high-dose chemotherapy with PBSC rescue. Since only a few drugs have demonstrated substantial activity in cisplatin-refractory disease, paclitaxel will be used in early salvage strategies and, possibly, as first-line chemotherapy as a part of platinum-based combination regimens in patients with testicular cancer. Further trials confirming the important role of paclitaxel in this highly curable malignancy and a thorough investigation of its acute and long-term toxicity will be the future tasks.

The aim of this study was to evaluate the clinical efficacy and safety of docetaxel (Taxotere) in patients with adenocarcinoma of the upper gastrointestinal tract previously untreated with cytotoxic chemotherapy. Docetaxel 100 mg m-2 was administered as a 1 hour intravenous (IV) infusion every 3 weeks to 41 patients. Patients were premedicated prior to each course with dexamethasone, diphenhydramine and cimetidine. Clinical response and toxicity were determined. Objective responses were seen in seven of 41 eligible patients (two complete responses [CRs] and five partial responses [PRs], for an objective response rate of 17% (90% confidence interval [CI], 8% to 30%). The most common toxicity was grade 4 neutropenia, which occurred in 88% of patients; 46% of patients required a dose reduction following an episode of neutropenic fever requiring antibiotic therapy. Additional patients have had reversible grade 3-4 toxicities including nausea, vomiting, stomatitis, diarrhea, fatigue and peripheral neuropathy. Ten patients have had grade 1-3 hypersensitivity reactions. Alopecia has been seen in the majority of patients. Fluid retention grade 1-3 has been observed in patients. Docetaxel administered on this schedule is an active agent in adenocarcinomas of the upper gastrointestinal tract. Further investigation of this drug should be conducted in multi-drug combination programs.

A phase II study was undertaken to evaluate the clinical efficacy and safety of docetaxel in patients with malignant melanoma. Between April 1992 and February 1996, 37 patients with metastatic malignant melanoma and no prior chemotherapy were treated with docetaxel 100 mg m-2 administered intravenously over 1 hour every 21 days. Patients were premedicated prior to each course with dexamethasone and diphenhydramine. Toxicity and follow-up were provided. Objective responses were seen in two out of 35 patients evaluable for response, one complete response and one partial response. These two responses were of a duration of greater than two years. The most common toxicity was grade 4 neutropenia, which occurred in 92% of patients; 49% required hospitalization for an episode of neutropenic fever. Additional patients had reversible grade 3-4 toxicities including nausea, vomiting, diarrhea, stomatitis, arthralgias, myalgias, peripheral neuropathy and fatigue. Eighteen patients had hypersensitivity reactions, two were grade 3-4. Fluid retention, grade 1-3 was observed in seven patients. Alopecia occurred in most patients. Docetaxel has definite but low-level activity against malignant melanoma. Further investigation of this drug should be considered in multidrug combination programs.

The aim of this study was to evaluate the efficacy of high-dose paclitaxel in patients with previously untreated stage IV epithelial ovarian cancer. Paclitaxel was administered intravenously over 3 h at a dose of 225 mg m(-2) on a 21-day cycle for six courses. Thirty-six patients were entered into this study; all 36 were assessed for toxicity and 33 patients were evaluable for response. One patient had a complete response and 12 patients had partial responses (overall response rate 39.4%, 95% CI 23-58%). The overall median duration of response was 9 months (range 3.5-23+ months). The response rate to carboplatin following failure of paclitaxel within 1 year of stopping therapy was 57% (four out of seven patients). The median survival of patients was 17.2 months. The main toxicity encountered was neutropenia which was WHO grade 3 in 11 patients (31%) and WHO grade 4 in seven patients (19%). Granulocyte colony-stimulating factor (GCSF) was not given to any patient during the study. Other toxicities were: grade 3/4 infection (11%) and nausea and vomiting (11%); grade 3 bone pain (22%), fatigue (14%), diarrhoea (3%), myalgia/arthralgia (3%) and dry eyes (3%). Transient peripheral neuropathy occurred in 16 patients (44%), and alopecia was encountered in most patients (grade 2/3, 78%). Paclitaxel given at 225 mg m(-2) to patients with stage IV epithelial ovarian cancer is active, well tolerated and does not require GCSF support.

To determine the characteristics of clinical illness accompanying Plasmodium falciparum infection induced by controlled exposure to infected mosquitoes, records of 118 volunteers participating in studies conducted between 1985 and 1992 were reviewed. One hundred fourteen volunteers (97%) reported at least one symptom attributable to malaria, with fatigue, myalgias or arthralgias, headache, and chills most commonly reported. The median duration of symptoms was 3 days. Fever was recorded in 61% of volunteers; 4 volunteers had temperatures >40 degrees C. Neutropenia and thrombocytopenia were present in 9% and 12% of volunteers, respectively. Despite counts as low as 658/microL (neutrophils) or 73,000/microL (platelets), no secondary infectious or hemorrhagic complications occurred. In all cases, volunteers recovered completely and laboratory values returned to baseline after specific antimalarial therapy. Recrudescence did not occur in any volunteer. In this model, mosquito inoculation of P. falciparum is a reliable, safe, and well-tolerated method of experimental challenge.

The antineoplastic agent mitoxantrone in combination with a corticosteroid (either prednisone or hydrocortisone) has shown clinical efficacy as palliative treatment for a proportion of patients (about 35 to 40%) with hormone-resistant advanced prostate cancer, a disease which predominantly affects elderly men and for which few systemic treatment options are available. Palliative end-points including pain relief, decreased analgesic use and reduced prostate specific antigen levels (a marker of tumour response) are reached in a greater percentage of patients receiving combination therapy than corticosteroid alone. In addition, there are generally greater improvements in quality-of-life parameters in mitoxantrone recipients. However, combined treatment offers no survival advantage over corticosteroid monotherapy. Neutropenia is the most common toxicity associated with mitoxantone therapy and may necessitate dosage reduction in some patients. Otherwise, mitoxantrone generally has a more favourable tolerability profile than has been established for other cytotoxic agents such as doxorubicin with regard to acute adverse events (e.g. nausea/vomiting, anorexia, constipation, alopecia, malaise/ fatigue, oedema) and cardiac toxicity. In conclusion, administration of mitoxantrone plus a corticosteroid can provide palliation for some elderly patients with hormone-resistant advanced prostate cancer, and is thus a valuable first-line treatment for this indication.

We previously reported results of a Phase II trial of UFT [Taiho Pharmaceutical Ltd., Tokyo, Japan; (BMS-200604) Bristol-Myers Squibb, Princeton, NJ], an oral 4:1 molar concentration of uracil and tegafur, plus oral leucovorin for metastatic colorectal carcinoma (Pazdur et al., J. Clin. Oncol. 12:2296-2300, 1994]. Our results demonstrated that a 28-day schedule of this combination produced a response rate similar to that obtained with conventional intravenous fluorouracil (5-FU)-plus-leucovorin regimens but without the severe or life-threatening neutropenia or oral mucositis that complicates intravenous 5-FU regimens. The current Phase I trial examines the dose-limiting toxic effects and maximum tolerated dose of a 14-consecutive-day schedule of UFT plus oral leucovorin in 14 patients who had histologically proven cancer and had received prior chemotherapy. The daily UFT plus leucovorin dose was divided into three doses administered orally every 8 hours. In this study, the UFT dose was escalated while the leucovorin dose remained at 150 mg/day. Of the 14 patients, 4 were initially treated at the 350-mg/m2/day UFT level for 14 days without any dose-limiting toxic reactions. Subsequently, another 7 patients were treated at the 400-mg/m2/day level; grade 3 diarrhea developed in 3 of these 7 (with severe abdominal cramping in 2 cases and severe nausea and vomiting unresponsive to antiemetics in the third). To better define the starting dose for phase II studies, an additional 3 patients were treated at the 350-mg/m2/day dose level. Of the total 7 patients treated at 350 mg/m2/day, grade 3 toxic events (diarrhea) developed in 2 patients. Grade 1-2 toxic effects noted at this level included fatigue, stomatitis, skin rash, abdominal pain, nausea, and vomiting. Neither partial nor complete responses were observed in this trial. The maximum tolerated dose of this schedule is 350 mg/m2/day UFT plus 150 mg/day oral leucovorin. However, because of this schedule's inferior dose intensity compared with that of the 28-day schedule of UFT plus leucovorin, subsequent development of UFT in the United States has focused on the 28-day regimen.

Topoisomerase I inhibitors are new compounds of interest for cancer chemotherapy. We performed a study with GI147211, a new semisynthetic camptothecin analogue, to determine the absolute bioavailability of the drug given orally. Patients with a histologically confirmed diagnosis of a solid tumour refractory to standard forms of therapy were eligible for the study. GI147211 was given orally on day 1 and as a 30-min infusion daily on days 2-5. The treatment course was repeated every 3 weeks. In subsequent patient cohorts, the dose of the oral formulation was escalated from 1.5 mg m(-2) to 6.0 mg m(-2); the dose for i.v. administration was fixed at 1.2 mg m(-2). Plasma pharmacokinetics was performed on day 1 and 2 of the first course and on day 1 of the second course using a validated high-performance liquid chromatographic assay. Nineteen patients were entered into the study; one patient was not evaluable because the treatment course was stopped prematurely. Eighteen patients received a total of 47 treatment courses. The absolute bioavailability of GI147211 averaged 1.3 +/- 5.2%. Drug appeared quickly in plasma with a median Tmax at 0.5 h. Fasting or fed state had no significant influence on the bioavailability of GI147211. The terminal half-life after administration of oral GI147211 was 6.85 +/- 3.13 h, similar to the half-life after intravenous administration. The major toxicities were neutropenia and thrombocytopenia. Nadirs for neutropenia and thrombocytopenia occurred on day 8 and day 15 respectively. Other toxicities predominantly consisted of mild and infrequent nausea and vomiting, and fatigue. The oral administration of the drug is well tolerated. Oral administration of topoisomerase I inhibitor GI147211 results in a low bioavailability with relatively wide interpatient variation. The intravenous route of administration is advised for further development of this promising topoisomerase I inhibitor.

A phase II study of combination paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ)/gemcitabine was conducted in patients with non-small cell lung cancer (NSCLC) who had failed first-line docetaxel- or cisplatin-based chemotherapy. Eligibility criteria included histologically confirmed measurable stage IIIB or IV NSCLC and previous exposure to docetaxel- or cisplatin-based regimens, World Health Organization performance status between 0 and 2, adequate hematologic parameters, and adequate hepatic, renal, and cardiac function. Gemcitabine (900 mg/m2) was given on days 1 and 8 as a 30-minute infusion; paclitaxel (175 mg/m2) was administered on day 8 as a 3-hour infusion after appropriate premedication. Granulocyte colony-stimulating factor (150 microg/m2 subcutaneously) was given on days 9 to 15. Treatment was repeated every 3 weeks until patients experienced disease progression. From October 1995 to December 1996, 26 patients with advanced NSCLC were enrolled (three stage IIIB, 23 stage IV). All 26 patients were assessable for toxicity, and 24 were evaluable for response. Two complete (8%) and five partial (21%) responses were observed, for an overall response rate of 29% (95% confidence interval, 11% to 47%). The median duration of response was 2.5 months and the median survival was 8 months. A median of three courses per patient was administered, and the median interval between courses was 21 days. The median delivered dose was 579 mg/m2/wk gemcitabine and 54.5 mg/m2/wk paclitaxel, corresponding to a relative dose intensity of 0.97 and 0.96, respectively. Grade 3/4 neutropenia occurred in two patients (8%). Grade 3 conjunctivitis occurred in one (4%) patient and grade 2/3 neurotoxicity in eight (31%) patients. Grade 3/4 and grade 2 fatigue occurred in four (15%) and eight (31%) patients, respectively. Other toxicities were mild to moderate. These preliminary results suggest that the paclitaxel/gemcitabine combination is an active and well-tolerated salvage regimen in patients with NSCLC previously treated with docetaxel- or cisplatin-based chemotherapy. The paclitaxel/gemcitabine combination merits further evaluation as first-line treatment.
