Based on the superior response rates (21% to 24%) of patients treated with single-agent paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) in Eastern Cooperative Oncology Group and M.D. Anderson Cancer Center trials in non-small cell lung cancer (NSCLC) and on the superior 1-year survival rates of NSCLC patients treated with carboplatin in a randomized study of cisplatin combination and analogues, we initiated a phase II trial of paclitaxel/carboplatin in patients with stage IV or effusion-positive stage III NSCLC. Eligibility stipulated chemotherapy-naive patients with measurable disease, good performance status, and adequate hematologic, hepatic, and renal function. Previous radiotherapy was restricted to < or = 30% of marrow-bearing bone. Paclitaxel was initially given at 135 mg/m2 over 24 hours followed by carboplatin dosed to a targeted area under the concentration versus time curve (AUC) of 7.5, with treatment repeated at 3-week intervals for six cycles. Granulocyte colony-stimulating factor was introduced during the second and subsequent cycles, with the paclitaxel dose sequentially escalated in 40 mg/m2 increments to a maximum dose of 215 mg/m2 in patients with less than grade 4 granulocytopenia and less than grade 3 thrombocytopenia. Of 54 patients enrolled, 30 currently are evaluable for response, 23 for toxicity. Myelosuppression has been the principal toxicity, with grade 3 or 4 granulocytopenia occurring in 70% of patients after the first cycle. After the introduction of granulocyte colony-stimulating factor, granulocytopenia decreased to 37% during the second cycle and then consistently to 20% or lower during subsequent cycles. Only 22% of cycles have been delayed for 1 week or more. Neutropenic fever has occurred in five (5%) of 100 evaluable cycles. Other grade 3 or 4 toxicities include thrombocytopenia (13%), anemia (9%), fatigue (9%), and hemorrhagic cystitis (1%). The paclitaxel dose was boosted to 215 mg/m2 in 12 (70%) of 17 patients by cycle 3 or 4. At an AUC of 7.5, the median first-cycle carboplatin dose was 434 mg/m2 (range, 293 to 709 mg/m2). The objective response rate is 50%, with three complete, 12 partial, and five minor responses. We conclude that the paclitaxel/carboplatin combination is active in advanced NSCLC and, with AUC-based dosing of carboplatin, can be given at 3-week intervals. Although dose limiting at a paclitaxel dose of 135 mg/m2, granulocytopenia can be reduced substantially with granulocyte colony-stimulating factor, allowing sequential dose escalation of paclitaxel to 175 mg/m2 and 215 mg/m2 in 70% of patients receiving three or more cycles.

The objectives of the present study were first to analyse the in vitro cytotoxic interactions between paclitaxel and vinorelbine in order to approach the optimal clinical scheduling in cancer patients, and second to determine the maximum-tolerated doses of this combination without haematopoietic growth factor in breast cancer patients previously exposed to anthracyclines. The in vitro cytotoxicity of paclitaxel and vinorelbine alone, in combination and in sequence, was evaluated against the established human doxorubicin-resistant MCF7 (MCF7-R) breast carcinoma cell line using the standard isobologram methodology. Regarding the simultaneous exposure to vinorelbine and paclitaxel, the combined data points fell mainly on the left side of the envelope of additivity suggesting a synergistic interaction. Conversely the representative isobologram of MCF7-R cells for sequential exposure to vinorelbine followed by paclitaxel or paclitaxel followed by vinorelbine indicated antagonism. These results prompted us to perform a trial of paclitaxel/vinorelbine combination using the administration of these drugs on the same day directly one after the other. The dose-escalation trial included 20 women with metastatic breast cancer who were treated by paclitaxel every 3 weeks (135 mg/m2 starting dose) with 20 mg/m2 steps in subsequent cohorts of patients and vinorelbine (30 mg/m2 fixed dose). Patients were treated every 21 days. A total of 91 courses of therapy were administered to patients at three dose levels. Neutropenic fever was the dose-limiting toxicity at level 3 (paclitaxel 175 mg/m2). Other significant toxicities included sensory neuropathy, myalgias and fatigue. We conclude that paclitaxel 155 mg/m2 and vinorelbine 30 mg/m2 administered directly one after the other on the same day, every 21 days, are the doses recommended for further study.

This study was performed to determine the clinical activity and safety of paclitaxel in the treatment of patients with refractory or relapsing aggressive Non-Hodgkin's lymphoma (NHL). Between May 3, 1994 and February 16, 1996, 39 patients with refractory or relapsing NHL consented to be enrolled in two, multicenter, open-labelled studies to evaluate the efficacy, safety, time to progression and overall survival of paclitaxel given at a dose of 175 mg/m2 by a 3-hour IV infusion every three weeks without G-CSF use. Data from the two studies is combined. One patient, although registered, did not receive treatment. Of the remaining 38 patients, 17 men and 21 women aged 26-82 years (median 60) were given 104 courses of paclitaxel [median 2 (range 1-6)]. Seventeen patients had stage IV, 7 stage III, 8 stage II, 5 stage 1 and 1 unknown stage of disease. Histologic grades included 1 low, 33 intermediate, and 4 high. Three patients had bone marrow involvement. Median time from diagnosis to study entry was 19 months (1-160). The median number of previous chemotherapy regimens was 2 (range 1-6). Three of the 35 (8.6%) patients evaluable for response had partial remission (PR) of their disease for 1-7 months (median 2) and 11/35 (31.4%) stable disease (SD) for 1 to 19 months (median 3). All three responders and 3 of the 11 SD patients had received paclitaxel after relapsing from a CR. At analysis, nine of the 38 patients were alive. Median duration of follow up at analysis was 6 months (3 days-29 months). The estimated survival rates for all patients at 1 and 2 years are 34% and 27%, respectively (Kaplan-Meier) from the start of paclitaxel treatment. The median survival time was 5.4 months (3 days to 28+ months). Febrile neutropenia occurred in two patients. Seven (18%) patients developed a neutrophil nadir of < 0.5 x 10(9)/L and 2 (5%) patients developed a platelet nadir of < 50 x 10(9)/L. Six patients received blood transfusions. Non-hematologic toxicity was generally mild to moderate with all patients experiencing some toxicity. Twenty-seven patients experienced grade III toxicity including: alopecia (n = 19), pain (n = 9), fatigue (n = 5), nausea/vomiting (n = 3), diarrhoea (n = 2), pulmonary/shortness of breath (n = 2), anorexia (n = 1) and fluctuating levels of consciousness and somnolence (n = 1). Two patients experienced grade IV toxicity (infection, peripheral neuropathy, pain). No patient discontinued paclitaxel for a severe hypersensitivity reaction. In summary, administered as a 3-hour infusion, paclitaxel 175 mg/m2 results in mild myelotoxicity but minimal antitumor activity in patients with refractory NHL.

Dose-dense sequential chemotherapy appears to be a promising approach in the management of patients with operable breast cancer. We evaluated the tolerability of such a novel chemotherapeutic regimen in high-risk patients. From February 1995 until September 1997, 49 women with histologically confirmed breast cancer and > or =10 involved axillary nodes were treated postoperatively with three cycles of epirubicin (110 mg/m(2)) followed by three cycles of paclitaxel (250 mg/m(2) in a 3-hour infusion) followed by three cycles of 'intensified' CMF (cyclophosphamide 840 mg/m(2), methotrexate 57 mg/m(2), fluorouracil 840 mg/m(2); E-T-CMF). All cycles were repeated every 2 weeks with G-CSF support. Ovarian ablation with monthly injections of triptorelin for 1 year was performed in premenopausal patients and tamoxifen was prescribed for 5 years to all women with positive receptor status after the completion of chemotherapy. A total of 456 cycles of chemotherapy were administered, 363 (80%) of them at full dose. Forty-seven (96%) patients received all 9 cycles of chemotherapy. Relative dose intensity of epirubicin was 0.98, of paclitaxel 0.97, of cyclophosphamide 0.99, of methotrexate 0.98 and of fluorouracil 0.99. Grade 3--4 toxicities included anemia (8%), leukopenia (8%), peripheral neuropathy (6%), neutropenia (4%), thrombocytopenia (4%), stomatitis (2%), diarrhea (2%), fatigue (2%) and hypersensitivity reaction (2%). Febrile neutropenia occurred in 2 patients. Alopecia was universal. After a median follow-up of 3 years, 11 women (22%) relapsed and 4 (8%) died. The 3-year actuarial disease-free survival rate was 72% and the 3-year overall survival rate 90%. The E-T-CMF regimen is well tolerated, as adjuvant treatment, in patients with operable breast cancer with promising activity and deserves further evaluation in phase III studies.

Neutropenia and anaemia are serious complications of myelosuppressive chemotherapy. They have a negative impact on patient quality of life and may reduce response to treatment. Febrile neutropenia, a potentially life-threatening complication of neutropenia, frequently requires hospital admission, while fatigue and weakness from anaemia reduce patient's capacity for activity. Pegfilgrastim and darbepoetin alfa, were designed to simplify and optimise treatment for patients with cancer. Once-per-cycle pegfilgrastim is as effective as daily filgrastim with respect to duration of severe neutropenia (DSN) and may have a lower incidence of febrile neutropenia than filgrastim. Darbepoetin alfa has enhanced biological activity and a serum terminal half-life three-fold longer than that of erythropoietin (EPO), which translates into rapid and sustained correction of anaemia with less frequent dosing. These novel cytokines have the potential to simplify the management of neutropenia and anaemia with fewer injections and less disruption to patients daily lives.

Docetaxel was chosen for study in the combination chemotherapy of advanced non small-cell lung cancer on the basis of its reproducible high single-agent activity, novel mechanism of action, and relative lack of neurotoxicity. Preclinical and clinical data suggested schedule-dependent synergism with vinorelbine. Trials of docetaxel and vinorelbine have explored a variety of schedules. One approach has been to give docetaxel on day 1 of a 3-week cycle with vinorelbine on day 0 or days 1 and 5. Febrile neutropenia and non-neutropenic infections have been dose limiting, and low-dose intensity (8-13 mg/m2/week) of vinorelbine has been achieved. Our phase I study showed that docetaxel 60 mg/m2 and vinorelbine 45 mg/m2 every 2 weeks could be safely given with prophylactic filgrastim. In the ensuing phase II trial, we observed a 51% confirmed response rate in 35 patients (95% confidence interval [CI]: 34-68). With a median follow-up of 12 months, the predicted median and 1-year survivals are 14 months and 60%, respectively. Use of prophylactic filgrastim and the every-2-week schedule of administration allowed for single-agent dose intensity of both drugs to be given. Febrile neutropenia occurred in five patients and 5/384 cycles. Cumulative toxicities of excessive lacrimation, fatigue, and onycholysis were observed. More recently, a weekly schedule of administration for both drugs has been studied. Docetaxel and vinorelbine appear highly active together when given on an every-2-week schedule with prophylactic filgrastim, and the combination may offer one alter-native to cisplatin-based therapy. However, confirmatory phase II and III studies are needed. Certain cumulative toxicities (onycholysis, lacrimation) may limit the duration of therapy. Application of this regimen for a shorter period, such as in induction or postoperative settings, may provide optimal benefit while minimizing toxicity.

The main objectives of this phase II study were to determine efficacy and safety of the combination of UFT with Leucovorin and mitomycin C in patients with metastatic colorectal cancer. Ninety-seven patients were treated with UFT (91 patients 300 mg/m2, 6 patients 250 mg/m2) + Leucovorin 90 mg days 1-28 q 5 weeks. During the first 4 cycles the patients also received mitomycin C 7 mg/m2 on day 1. At the end of 4 courses patients with benefit from the treatment could receive further courses of UFT and Leucovorin alone. Two patients had a complete response (2%), 20 (21%) had a partial response, 40 (41%) had no change, 19 (20%) had progression, and 16 (17%) were not evaluable for response. The overall response rate by intention to treat was 22/97 (23%). Median time to progression was 5 months and median survival 13 months. Severe (grade 3-4) toxicities included: anorexia 3%, nausea 6%, vomiting 7%, diarrhoea 7%, and fatigue 9%. Febrile neutropenia, renal failure, and thrombocytopenia were seen in 1% of the patients, respectively. The combination of UFT with Leucovorin and mitomycin C shows similar clinical activity with regard to overall response rate (23%) and survival (13 months) to other frontline 5-fluorouracil-based therapies in metastatic colorectal cancer patients. The results indicate that mitomycin C did not increase either efficacy or toxicity. Therefore, phase III trials with this regimen cannot be recommended.

Aim of this study was to evaluate activity and toxicity of docetaxel and carboplatin as second-line treatment in advanced non-small-cell lung cancer (NSCLC) patients who failed or relapsed after previous chemotherapy. Patients had to have unresectable stage IIIb or IV NSCLC, previous chemotherapy, a performance status < or = 2, a normal bone marrow reserve, and an adequate renal and liver function. Treatment consisted of docetaxel 75 mg/m2 and carboplatin AUC 6 mg/ml min administered every 3 weeks for a maximum of 5 cycles. Fifty-seven patients with a median age of 57 years were included. Prior treatment consisted of gemcitabine alone (n = 2) or gemcitabine in combination with cisplatin (n = 26) or epirubicin (n = 29). Median number of cycles for carboplatin and docetaxel was 4. Granulocytopenia and thrombocytopenia common toxicity criteria (CTC) grades 3 and 4 occurred in 79 and 30% of patients, respectively. Febrile neutropenia occurred in eight patients (14%), of whom two patients died. Fatigue grades 2 and 3 occurred in 42% of patients. Other non-haematological toxicity was mild. Tumour response rate was 37%, irrespective of the previous regimen. Median survival was 31 weeks, 1-year survival was 32%. In conclusion, the combination of docetaxel and carboplatin is active as second-line treatment in platinum and non-platinum pre-treated patients.

BBR3464, a novel tri-nuclear platinum complex, forms long-range DNA adducts and is highly potent when compared with cisplatin in vitro. Preclinical studies demonstrated activity in cisplatin-resistant tumours and tumours with mutated p53 status. Phase I & II clinical studies gave preliminary indications of activity in melanoma, pancreatic, lung and ovarian cancers. The aim of this study was to determine the efficacy and confirm the toxicity of BBR3464 when given either as first- or second-line treatment for advanced disease in patients with gastric and gastro-oesphageal adenocarcinoma. Two multicentre, open label, Gehan design studies were conducted; one study used BBR3464 as first-line and the other as second-line treatment for metastatic or locally advanced disease. Nineteen first-line and 26 second-line patients were enrolled receiving a total of 74 and 53 infusions, respectively. Initially, seven patients in the second-line study received BBR3464 using the planned schedule of 1.1 mg/m2 every 4 weeks; however, 5 of these patients experienced dose-limiting grade 3 or 4 febrile neutropenia; subsequent patients in both studies were treated using the modified schedule of 0.9 mg/m2, every 21 days. In 1 of 17 evaluable, previously untreated patients, regression of multiple skin lesions was noted with stabilisation of lung metastases and maxillary sinus mass, lasting 155 days. In the first-line study, the median time to progression was 85 days [95% Confidence Interval (CI): 42, 127] (2.8 months) and in the second-line study, the median time to progression was 71 days [95% CI: 42, 109] and 38 days [95% CI: 32, 73] in the 1.1 and 0.9 mg/m2 dose level groups, respectively. Toxicity data were available for 45 patients. Neutropenia was the main toxicity seen (G3: 40%, G4: 40%). Febrile neutropenia was observed in six patients (15%) treated with 0.9 mg/m2 compared with five patients (71%) treated with 1.1 mg/m2 BBR3464. Other drug-related toxicities (G3/4) included: anaemia, thrombocytopenia, nausea, vomiting, diarrhoea, mucositis and fatigue. Diarrhoea and nausea/ vomiting were adequately controlled by the use of loperamide and antiemetics, respectively. Recruitment to the second-line study was closed early due to the poor response rate (1/17 evaluable, 6%; 95% CI: 1%, 27%) and short time to progression noted in the first-line study. Further studies with BBR3464 in this tumour type are not recommended.

The aim of this study was to determine the maximum tolerated dose (MTD) of intraperitoneal (i.p.) topotecan combined with standard doses of intravenous (i.v.) carboplatin and paclitaxel and to investigate its pharmacokinetics. Women with primary ovarian cancer stage IIb - IV received six cycles of i.v. carboplatin and paclitaxel with escalating topotecan doses i.p. of 10, 15, 20 and 25 mg/m(2). Twenty-one patients entered this trial. Febrile neutropenia, thrombocytopenia requiring platelet transfusion and fatigue grade 3 were dose-limiting toxicities (DLT) at 25 mg/m(2) i.p. and 20 mg/m(2) i.p. of topotecan was considered to be the MTD. The mean plasma t(1/2) was 3.8 +/- 2.3 h for total topotecan and 4.4 +/- 3.9 h for active lactone. The area under the curve (AUC) was proportional with dose, R = 0.54, p < 0.05 for total topotecan and the peritoneal / plasma AUC ratio was 46 +/- 30. Fifteen patients who completed treatment had a median progression-free survival (PFS) of 27 months. In this setting the MTD of topotecan is 20 mg/m(2) i.p. The efficacy of this regimen should be explored further in a formal phase III study.
