First-in-man phase I study assessing the safety and pharmacokinetics of a 1-hour intravenous infusion of the doxorubicin prodrug DTS-201 every 3 weeks in patients with advanced or metastatic solid tumours.

PURPOSE: DTS-201 is a doxorubicin (Dox) prodrug that shows encouraging data in experimental models in terms of both efficacy and safety compared with conventional Dox. The purpose of this phase I study was to assess the safety profile, to establish the recommended dose (RD) for clinical phase II studies and to assess potential anticancer activity of the compound. EXPERIMENTAL DESIGN: DTS-201 was administered as a 1-hour infusion every 3 weeks in eligible patients with advanced solid tumours according to common clinical phase I criteria. Dose escalation was performed according to a modified Fibonacci schema. RESULTS: Twenty-five patients with a median age of 58 years (range, 30-72) were enrolled in the study. The median number of treatment cycles was 2 (range, 1-8). DTS-201 was administered at four dose levels (DLs) ranging from 80 to 400 mg/m2, which is equivalent to 45-225 mg/m2 of conventional Dox. No dose-limiting toxicity (DLT) occurred at the first two DLs. Three DLTs were observed at DL3 and DL4 (diarrhoea for DL3, vomiting and neutropenia for DL4). DL4 (400 mg/m2) was considered the maximum tolerated dose. Myelosuppression was the main toxicity, and NCI-CTC grade III-IV neutropenia was common at RD. Non-haematological adverse reactions were mild to moderate and included nausea, anorexia, asthenia and alopecia. No treatment-related severe cardiac adverse events were observed. CONCLUSIONS: DTS-201 is well tolerated and safe in heavily pretreated solid tumour patients. A high equivalent dose of Dox could be delivered without severe drug-related cardiac events. DTS-201 showed evidence of clinical activity with a confirmed partial response in a patient with soft-tissue sarcoma. The recommended phase II dose is 400 mg/m2.

Sequential vinorelbine-capecitabine followed by docetaxel in advanced breast cancer: long-term results of a pilot phase II trial.

PURPOSE: To evaluate the response rate of the combination of capecitabine (C) and vinorelbine (V) followed by Docetaxel (D) in the 1st line treatment of advanced and metastatic breast cancer patients. PATIENTS AND METHODS: Patients with measurable disease and no prior chemotherapy in advanced disease were eligible. Pts received V 25 mg/m(2) on day 1 and 8 in combination with C 825 mg/m(2) twice a day from day 1 to 14 every 3 weeks for four cycles followed by 12 consecutive weeks of D 25 mg/m(2)/w. RESULTS: Between March 2002 and November 2003, 40 patients were enrolled. Median age was 57 years. Of patients, 77.5% of pts had visceral involvement and 32.5% had more than two metastatic sites. In the adjuvant setting, 62.5% received anthracycline and 10% Taxanes. In the intent-to-treat population, an overall objective response was observed in 25 patients (62.5, 95% CI, 45.8-77.27) and stable disease in 5 (12.5%). Median time till progression (TTP) was 12.3 months (range 1.5-48; 95% CI, 10.05-14.54). The median survival was 35.7 months (range 2-47). Reported grade 3-4 toxicities under Navcap were neutropenia (4 pts), anemia (1 pt), thrombopenia (1 pt) and febrile neutropenia (3 pts). Reported grade 3-4 toxicities under weekly Docetaxel were neutropenia (1 pt), thrombopenia (2 pts), leucopenia (1 pt) and anemia (1 pt). CONCLUSION: The sequential use of Navcap followed by weekly Docetaxel demonstrated an interesting efficacy with a prolonged TTP and OS and warrants further evaluation.

Phase II trial of capecitabine and vinorelbine as first-line chemotherapy for metastatic breast cancer patients.

BACKGROUND: Vinorelbine is one of the most active cytotoxic agents in metastatic breast cancer. Its association with 5-Fluorouracil generates objective responses, varying between 44 and 55%, and improves the tolerance profile. The aim of this multicenter phase II trial was to assess the combination of capecitabine and vinorelbine as first-line chemotherapy in patients with metastatic breast cancer (MBC). PATIENTS AND METHODS: Thirty patients with MBC received a 3-week cycle combining capecitabine 825 mg/m2 twice a day on days 1 through 14, with 25 mg/m2 of vinorelbine on days 1 and 8. Treatment continued until progression, unacceptable toxicity or patient refusal to continue. The median age was 54 years (30-77) and the median WHO-PS was 1. Twenty patients (67%) received adjuvant chemotherapy including anthracycline and taxanes. RESULTS: Objective responses occurred in 21 patients (70%). Stable disease lasting more than 6 months was observed in six patients (20%). The clinical benefit rate was 90%. The median progression-free survival and overall survival were 10 months and 30.4 months, respectively. The most frequent treatment-related toxicities were: WHO grades 3 and 4 neutropenia (two patients), febrile neutropenia (two patients), grade 3 asthenia (two patients) and grade 3 nausea/vomiting (one patient). No grade 3 hand-foot syndrome was observed. CONCLUSION: The combination of capecitabine and vinorelbine is an active and safe regimen for first-line treatment of MBC.

Vinorelbine and cisplatin in advanced squamous cell carcinoma of the cervix: the South African experience.

BACKGROUND: This phase II trial was performed to assess the activity and safety of the cisplatin and vinorelbine combination in patients with advanced cervical carcinoma. PATIENTS AND METHODS: Forty-two patients with advanced cervical cancer were included in the study to receive vinorelbine at 30 mg/m2 on d 1 and d 8 and cisplatin 100 mg/m2 on day 1 every 4 weeks. RESULTS: Thirty-seven patients were evaluable for response and 40 patients for tolerance. Twenty-four patients (64.8%) achieved objective responses. The median duration of response was 17.5 months (range 2.5-57 months), median time to progression was 13.2 months (range 0.4-57 months) and median survival was 20.6 months (range 0.4-55 months). This regimen was well-tolerated; no WHO grade 4 neutropenia was observed, grade 3 nausea and vomiting occured in 50% of patients and grade 2 peripheral neuropathy in 5% of patients. CONCLUSION: Vinorelbine-cisplatin is an active and well-tolerated regimen in advanced cervical carcinoma.
