Thirty-five patients with metastatic breast cancer (MBC) entered a phase II study of pegylated liposomal doxorubicin 35 mg/m2 intravenously (i.v.) on day 1 plus vinorelbine 30 mg/m2 i.v. on day 1 every 4 weeks. Patients were required to have measurable disease, previous chemotherapy with an anthracycline-containing regimen, and a normal left ventricular ejection fraction (LVEF). Thirty-four patients were assessable for response and toxicity. The overall response rate (on an intent-to-treat basis) was 35% (12 of 34; 95% CI, 20%-54%). One complete response and 11 partial responses were noted. In addition, 14 patients (41%) had stable disease of > 4 months duration, and 7 patients (20.5%) had disease progression. The response rates to the combination when it was used as first- and second-line chemotherapy were 31% (4 of 13) and 38% (8 of 21), respectively. Median time to disease progression was 7 months (range, 1-35 months) and median overall survival was 13 months (range, 2 to > 62 months). Neutropenia was the most frequent toxicity (grade 4 in 44% of patients and 19% of cycles), but neutropenic fever was seen in only 3 cases. No septic deaths occurred. Nonhematologic grade 3 side effects included skin toxicity (palmar-plantar erythrodysesthesia syndrome, 6%) and mucositis (15%). Late alopecia was seen in 53% of patients (grade 1 in 41%, and grade 2 in 12%). The median LVEFs were 64% (range, 50%-81%) at baseline and 62% (range, 37%-70%) after treatment. Three patients presented an LVEF decrease to < 50%; however, no clinical heart failure was noted, and 2 of these patients recovered normal values after cessation of therapy. The combination of pegylated liposomal doxorubicin and vinorelbine can be safely administered to patients with anthracycline-pretreated MBC and is active in this population.

The purpose of the study was to evaluate the antitumor activity and the safety of paclitaxel combined with gemcitabine and cisplatin in patients affected by advanced transitional cell carcinoma of the urothelium (TCC). Eighty-five patients affected by advanced TCC and measurable disease were randomized to receive either paclitaxel at dosage of 70 mg/m2, gemcitabine 1000 mg/m2 and cisplatin 35 mg/m2 on days 1 and 8 every 3 weeks (GCP) or gemcitabine 1000 mg/m2 on days 1, 8, 15 and cisplatin 70 mg/m2 on day 2 every 4 weeks (GC). All enrolled patients were considered evaluable for response and toxicity (intention to treat). The observed response rate was 43% for GCP and 44% for GC combination, respectively. Median time to treatment failure was 32 weeks for GCP and 26 weeks for GC and overall survival 61 vs 49 weeks, respectively (p-value not significant). Grade 3-4 neutropenia was observed in 49% of patients treated with GCP vs 35% of those treated with GC (P=0.05) and grade 3-4 thrombocytopenia was observed in 36% of GCP treated patients as compared to 21% of those treated with GC (P=0.01). Seven patients over 70 years old or with poor PS were removed from the study: 6 patients from GCP group (2 toxic deaths, 2 grade 4 myelotoxicity and 2 grade 3 asthenia) and 1 from GC group was lost to follow-up after the first cycle. The combination of paclitaxel, gemcitabine and cisplatin is effective in the treatment of TCC. However, the addition of paclitaxel to the combination of gemcitabine plus cisplatin seems to increase toxicity, therefore it seems not suitable for poor PS patients and those over 70 years old. Larger and more powered studies are needed to exactly define the role of paclitaxel in this combination.

We studied the activity of T138067-sodium in patients with malignant gliomas. T138067-sodium is a unique new chemotherapy agent that inhibits microtubule formation by binding irreversibly and specifically to beta(1), beta(2)and beta(4) isotypes of 3-tubulin, causing cell arrest at G(2)/M and inducing apoptosis. Patients with recurrent anaplastic astrocytoma or glioblastoma multiforme were treated intravenously with 330 mg/m(2) of T138067-sodium weekly. Treatment was continued until the patient experienced either unacceptable toxicity or progressive disease. Patients had to have histologically proven glioma, have bidimensionally measurable disease at least 1 cm x 1 cm, and have received no more than one prior adjuvant chemotherapy. No chemotherapy or radiotherapy for recurrent disease was permitted. Nineteen patients entered the trial. One patient was found to be ineligible. There were two patients with anaplastic astrocytoma and 16 with glioblastoma multiforme. Only two patients had received prior adjuvant chemotherapy. The first seven patients had full pharmacokinetic sampling. No dose-limiting toxicity was seen, and pharmacokinetic results were consistent with those from nonglioma patients. The most common drug-related effects were fatigue (33%), nausea (28%), neutropenia (28%), and anorexia (17%). No patients stopped the study because of toxicity. No responses were seen in the 15 eligible patients who completed at least one cycle. Three patients had stable disease with a median duration of 2.6 months. Our results suggest that given in this dose and schedule T138067-sodium does not have activity in this population of anaplastic astrocytoma and glioblastoma multiforme.

Recent studies of docetaxel have demonstrated improved survival over mitoxantrone and prednisone in patients with hormone-refractory prostate cancer (HRPC), supporting the study of novel docetaxel-containing regimens as primary therapy or following initial docetaxel-based therapy. To evaluate the combination of docetaxel and vinorelbine in the treatment of patients with HRPC, 40 patients with proven adenocarcinoma of the prostate with progressive metastatic disease despite androgen ablation were enrolled onto this phase II trial. Patients were treated with docetaxel 60 mg/m2 on day 1 and vinorelbine 15 mg/m2 on days 1 and 8 of a 21-day cycle. All patients received dexamethasone 8 mg twice daily for 4 days starting 1 day prior to the docetaxel infusion. After the first three patients were enrolled, filgrastim was added on days 2-6 and 9-13. Of the 40 patients enrolled, 19 had no prior chemotherapy and 21 had received at least one prior chemotherapy regimen. Of the 19 patients without prior chemotherapy and the 21 with prior chemotherapy, 7 (37%) and 6 (29%) , respectively, demonstrated a decrease in prostate specific antigen by > 50% maintained for at least 4 weeks. Out of eight patients with measurable disease, one achieved a partial response and four demonstrated stable disease. There was one patient with deep vein thrombosis, and febrile neutropenia was noted in only three patients after the protocol was modified to include filgrastim support. The combination of docetaxel and vinorelbine with filgrastim was well tolerated and active against HRPC in patients with or without prior chemotherapy.

We evaluated the antitumoral efficacy and safety of CPT-11 125 mg/m2 (weekly 90 min i.v. infusion; days 1, 8 and 15) combined with UFT (oral combination of tegafur and uracil) 200 mg/m2/day plus leucovorin (LV) 45 mg/m2/day (both divided into three separate oral doses every 8 h, days 1-21) every 4 weeks as first-line chemotherapy of metastatic colorectal cancer (CRC). Fifty-three patients > or =18 years old with histologically confirmed diagnosis of advanced CRC and bidimensionally measurable disease were enrolled. Three patients (6%) showed CR and 8 patients (15%) showed PR (ORR = 21% (95% CI, 10-32). Stable disease was reported in 19 patients (36%) [tumor control rate = 57% (95% CI, 43-70)]. The median time to progression and overall survival were 7.9 and 18.2 months, respectively (1-year rate = 74%; 2-years rate = 26%). CPT-11/UFT/LV treatment was well tolerated: the most reported grade 3/4 toxicities were neutropenia (11% of patients) and delayed diarrhea (28% of patients). No significant differences in response rate, survival or toxicity were found between younger (< or =65 years) and older patients (> 65 years). Weekly CPT-11 plus UFT/LV was found effective and safe as first-line chemotherapy for metastatic CRC. The addition of CPT-11 to UFT/LV doubled the response rate compared to the results previously reported with UFT/LV, while myelosuppression remained low.

Capecitabine and gemcitabine are used in the treatment of a variety of solid tumors including pancreatic and biliary tract carcinomas. The authors evaluated survival, response, and toxicity associated with using a combination of capecitabine and gemcitabine to treat patients with unresectable or metastatic gallbladder adenocarcinoma (GBC). Eligible patients had histologically- or cytologically-confirmed GBC, no prior systemic therapy with capecitabine or gemcitabine, Karnofsky Performance Status 70%, serum total bilirubin up to three times normal, and measurable disease. Treatment consisted of gemcitabine 1000 mg/m2 IV on Days 1 and 8 concurrent with administration of capecitabine 1000 mg/m2 PO BID on Days 1 through 14, on a 3-week cycle. Tumor response was assessed by the response evaluation criteria in solid tumors (RECIST criteria) and survival was calculated from initiation of CapGem therapy. A total of 24 patients were enrolled. Median age at the time of diagnosis was 62 years (range, 41-78 years). Fourteen patients had undergone prior surgery. Results showed that eight patients achieved partial response (33%) with an additional 10 patients achieving stable disease (42%). The overall median time to disease progression was 6.0 months (95% CI, 3.8-8.1 months) and overall survival was 16 months (95% CI, 13.8-18.3 months). The one-year survival rate was 58%. No Grade 4 toxicity was seen. Transient Grade 3 neutropenia/ thrombocytopenia and manageable nausea, hand-foot syndrome and anorexia were the most common toxicities. Our study shows that CapGem is an active and well-tolerated chemotherapy regimen in patients with advanced GBC.

Sabarubicin (MEN-10755), a new synthetic anthracycline analogue, was evaluated for safety and efficacy in a multicentre phase II study in patients with advanced hormone refractory prostate cancer (HRPC). Thirty seven patients were included, of which 34 were evaluable for PSA response according to Bubley's criteria. Sabarubicin was administered as a short (30 min) intravenous infusion at a dose of 80 mg/m(2) every 3 weeks. The main toxicity consisted of grade 3/4 neutropenia in 24 patients (64.9%), with grade 3/4 febrile neutropenia occurring in one patient only. Grade 3/4 cardiotoxicity was observed in 4 patients including one ineligible. Other toxicities were mild. Nine patients achieved a PSA response (26.5%), 10 patients had stable disease (29.4%) and 14 patients disease progression (41.2%). One patient (2.9%) had a PSA response that was not confirmed by repeat PSA testing. The objective response rate according to RECIST criteria was 6.7% in 15 patients with measurable disease. The median duration of PSA responses was relatively long 7.1 months (95% CI 4.9-20.7) as was the median time to treatment progression in patients with stable disease. The median overall survival was 18.7 months (95% CI 9.1-N), comparable to results recently observed in taxotere-containing regimens. To confirm and extend these results, further testing of sabarubicin in larger trials is warranted.

The aim of the study was to determine the dose-limiting toxicity and maximum tolerated dose of a first-line combination of doxorubicin and gemcitabine in adult patients with advanced soft tissue sarcomas and to explore its activity and toxicity, and the presence of possible interactions between these agents. Patients with measurable disease were initially treated with doxorubicin 60 mg m(-2) by i.v. bolus on day 1 followed by gemcitabine at 800 mg m(-2) over 80 min on days 1 and 8, every 21 days. Concentrations of gemcitabine and 2',2'-difluorodeoxyuridine in plasma, and gemcitabine triphosphate levels in peripheral blood mononuclear cells were determined during 8 h after the start of gemcitabine infusion. Myelosuppression and stomatitis were limiting toxicities, and the initial dose level was applied for the Phase II trial, where grade 3-4 granulocytopenia occurred in 70% of patients, grade 3 stomatitis in 46% and febrile neutropenia in 20%. Objective activity in 36 patients was 22% (95% CI: 9-35%), and a 50% remission rate was noted in leiomyosarcomas. Administration of doxorubicin preceding gemcitabine significantly reduced the synthesis of gemcitabine triphosphate. Clinical activity, similar to that of single-agent doxorubicin, and the toxicity encountered do not justify further studies with this schedule of administration.

Twelve patients with metastatic breast cancer previously exposed to taxanes were treated on a Phase II trial with ixabepilone. Eligible patients had histologically confirmed metastatic breast cancer with measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST), and adequate hematopoietic, renal, and hepatic function. Ixabepilone 8 mg/m(2)/day was given intravenously daily for 3 days for the first 3-week cycle and increased to 10 mg/m(2)/day for subsequent cycles if patients did not have hematologic or other toxicity after the first cycle. Patients continued treatment until progressive disease or unacceptable toxicity. Three, 29, and 33 of 65 cycles administered were at the 7 mg/m(2), 8 mg/m(2) and 10 mg/m(2) dose levels respectively. Grade 4 leukopenia (n=1), grade 3 neutropenia (n=2), grade 2 neuropathy (n=3), and grade 2 transaminase elevation (n=2) were the most notable toxicities. Ten patients had stable disease for at least 6 weeks. No complete or partial responses were observed in 12 evaluable patients treated with ixabepilone daily for 3 days. Although ixabepilone was well-tolerated, the dose of 8-10 mg/m(2) daily for 3 days is not an effective therapy in metastatic breast cancer previously exposed to taxanes.

Rebeccamycin analog (NSC 655649) is a synthetic antibiotic cytotoxic agent thought to inhibit topoisomerase function. We sought to determine the response rate to rebeccamycin analog among patients with refractory advanced breast cancer using two different treatment schedules. Eligible patients had measurable disease, central venous access, and one or two prior chemotherapy regimens for advanced cancer, or recurrence within 12 months of adjuvant chemotherapy. Patients were randomized to rebeccamycin analog on one of two treatment schedules: arm 1, 500 mg/m2 IV bolus every 21 days; arm 2, 140 mg/m2 IV bolus daily x 5 days, every 21 days. The primary study endpoint was response rate; a two stage accrual design evaluated each schedule separately. Forty-two women entered the trial, 21 on each arm. Prior chemotherapy regimens for metastatic breast cancer were: 0, n=4; 1, n=21; 2, n=17. Prior treatments (including adjuvant therapy) anthracyclines: 88%, taxanes 67%, 5FU-based therapy, 50%. There were 5 partial responses (overall response rate 12%), two in arm 1 and 3 in arm 2, all in patients with prior anthracycline-based adjuvant chemotherapy. Median time to progression was 2.1 months (range 1-14+ months). An additional 9 patients had stable disease as best response. Grade 3 or 4 toxicity rates were: anemia 5%, neutropenia 33%, thrombocytopenia 12%, RBC transfusion 14%, nausea/vomiting 10%. Toxicity profiles were similar between the treatment arms. Rebeccamycin analog is reasonably well tolerated on two different treatment schedules for advanced breast cancer, with modest clinical activity in this heavily pretreated population.
