This study investigated the therapeutic effect of single-agent i.v. weekly Navelbine (vinorelbine), a semisynthetic vinca alkaloid, in women who had received no prior treatment for locally advanced or metastatic breast cancer. Of 68 patients entered into the study, 63 were adequate inclusions, assessable for toxicity and response by WHO criteria; the 5 patients who were not evaluated were excluded from analysis because they were found not to meet the eligibility criteria of the study. Navelbine was given as a weekly 30 mg/m2 short i.v. (20 minutes) infusion; treatment was continued until disease progression. The overall response rate was 44% (complete response 8%, partial response 36%). The response rate according to target was lymph nodes, 62.9%; liver, 50.0%; lung, 50.0%; skin, 37.5%; and primary tumor, 30.8%. The median duration of response was 17.9 weeks (range: 7-52 weeks). The median time to treatment failure was 12.9 weeks, and the median survival was 50.3 weeks. The 63 eligible patients received 501 cycles. The mean dose intensity was 76%. At least one episode of WHO grade 3/4 granulocytopenia was seen in 46% of the patients (13.6% of cycles). Significant nausea/vomiting was seen in only 5% of patients corresponding to 1% of cycles. Only 5% of patients developed WHO grade 3-4 constipation and grade 3 peripheral neuropathy was observed in 1.6% of patients. Alopecia was rare (6.3% of patients), and other side effects were uncommon. This study confirms that Navelbine has major single-agent antitumor activity as frontline therapy in advanced breast cancer. Given its excellent tolerance profile and low morbidity, it should be recommended for inclusion in first-line combination chemotherapy regimens.

The Southwest Oncology Group studied the response rate and toxicity of mitoxantrone (7.5 or 10 mg/m2 to 12.0 mg/m2) and cis-platinum (100 mg/m2) in 30 patients with advanced breast cancer as second-line therapy. There were 2 partial responses in 29 eligible patients. Toxicity was considerable, with 27 patients having grade 3 or 4 toxicity. Grade 3-4 toxicity included vomiting, thrombocytopenia, granulocytopenia, leukopenia and anemia. The combination of mitoxantrone plus cis-platinum has minimal activity as second-line therapy in metastatic breast cancer.

A phase II study to test the toxicity and the efficacy of a weekly combination of Mitoxantrone, 5-Fluorouracil and L-Leucovorin (MFL) was carried out in 43 patients with metastatic breast cancer. Chemotherapy consisted of mitoxantrone 4 mg/m2, 5-fluorouracil 375 mg/m2, and L-leucovorin 100 mg/m2 on day 1, weekly. Patient characteristics were: median age 53 years (range 36-65); estrogen receptor (ER) status was known in 26 patients and of these 15 (57.7%) patients were ER-positive and 11 (42.3%) ER-negative. Of the 43 patients, 25 (58.1%) and 18 (41.9%) patients had received prior adjuvant chemotherapy and prior adjuvant endocrine treatment, respectively. MFL was administered to 22 (51.1%) patients as first line chemotherapy for advanced disease, while 21 (48.9%) patients had received 1 to 2 cytotoxic regimens for metastatic disease. The dominant sites of metastases were: soft tissue in 11 (25.5%) patients, bone in 8 (18.6%) patients and viscera in 24 (55.9%). All patients were assessable for toxicity: only 8 patients experienced WHO grade 3 leukopenia. Thrombocytopenia, diarrhea, stomatitis, and nausea/vomiting were negligible. Anemia and alopecia were not observed. Thirty-nine patients were assessable for response: overall response rate was 28.2% (complete response 7.7% and partial response 20.5%). Median duration of response was 12 months (range 6-34). Patients with no prior anthracyclines had a 42.1% response rate compared to 15% in patients who had received anthracyclines. Median overall survival of the 43 patients was 6 months (range 1-34). Weekly MFL is a well-tolerated and a moderately effective regimen for the treatment of metastatic breast cancer.

Carboplatin, a platinum analog with single-agent activity in previously untreated breast cancer, is characterized by comparatively less renal toxicity and emesis than cisplatin. We combined carboplatin at different dose levels [from 200 to 350 mg/m2 by intravenous (IV) infusion on day 1] with 5-fluorouracil (500 mg/m2 IV on days 1 and 8) and cyclophosphamide (500 mg/m2 IV on day 1), with all three drugs recycled every 28 days, to evaluate anti-tumor activity and toxicity of this novel combination [5-fluorouracil/carboplatin/cyclophosphamide (FCC)] in untreated locally advanced (LABC) or metastatic breast cancer (M+). Of 37 patients treated between March 1990 and August 1991 [LABC 25, M+ 8; World Health Organization (WHO) performance status, 0-1; median number of treatment cycles, 5; median follow-up, 20 months], 33 are evaluable for response and toxicity. The overall complete plus partial remission rate was 57% (LABC 68%, M+ 25%). The median duration of response was 19+ months. The cumulative carboplatin dose ranged from 800 to 2350 mg/m2 (median, 1450 mg/m2). In this series, no correlation was observed between the carboplatin dose level and response rate or toxicity. Leukopenia and thrombocytopenia represented the most frequent toxicities. WHO grades 3 and 4 neutropenia were documented in 34% and 8% of patients, respectively. Thrombocytopenia below 50 x 10(9)/l was observed in 8%. No renal toxicity was observed, and moderate emesis occurred in 67% of patients. These results indicate that FCC is an active and relatively safe combination for the treatment of advanced breast cancer in patients not previously treated with chemotherapy.

Twenty-seven women with metastatic breast cancer (at least one site of measurable disease) entered a phase II study of chronic oral etoposide (50 mg/m2/day x 21 days, given every 4 weeks). To date, 23 patients are evaluable for response and toxicity. All patients had received prior chemotherapy (adjuvant therapy, one patient; adjuvant plus chemotherapy for metastases, six patients; chemotherapy for metastases, 16 patients). Thirteen patients had previously received anthracyclines, and 10 had also received prior hormonal therapy. Of the 23 evaluable patients, one obtained a complete response and six achieved partial responses (objective response rate 30.4%, 95% confidence interval, 13 to 53%). Responses were seen in lymph nodes (three of eight sites), skin and soft tissue (five of seven), lung (two of six), lytic lesions of the bone (one of three), and liver (1 of 12). The median duration of responses was 6 months (range, 1+ to 8). The main toxic side-effects were leukopenia (74% of patients), thrombocytopenia (22%), and anemia (69.5%). Myelosuppression in four patients (17%) necessitated a 25% dose reduction. Other toxicities included alopecia (83%), mucositis (52%), and emesis (35%). Chronic oral etoposide appears to be an active regimen in metastatic breast cancer patients previously exposed to chemotherapy.

We performed a preliminary phase II clinical trial of MX2; 3'-deamino-3'-morpholino-13-deoxy-10-hydroxycarminomycin (KRN8602) in patients with metastatic breast cancer who had failed to respond to previous chemotherapeutic regimens after clinical evidence of systemic disease. Twelve patients at a single institute received KRN8602 at a dose of 35 mg/m2 intravenously once every three weeks. All the patients were followed-up until their disease progressed. There was one complete response lasting 17 weeks and one partial response lasting eight weeks. Among the 12 patients, World Health Organization (WHO) grades 3 and 4 neutropenia were observed in five and two patients, respectively. Grade 3 anemia was observed in three patients but severe thrombocytopenia was not observed. Grade 3 nausea/vomiting was observed in eight patients. Alopecia was not observed. The results of this preliminary phase II trial suggest a need for further testing of the anti-tumor activity of KRN8602 in patients with metastatic breast cancer.

Ninety-three evaluable patients with metastatic breast cancer previously treated with chemotherapy, received mitoxantrone as a single agent (14 mg/m2, by rapid intravenous infusion, once every 3 weeks). Patients received a median of 7 courses (range 2 to 18), with a mean cumulative total dose of 133 mg (range 36 to 342). A complete response (CR) was achieved in 2 patients (2%). Partial response (PR) was observed in 23 patients (25%). The overall response rate (CR+PR) was thus 27%, with a median duration of 9 months (range 3 to 18). Responses were observed in all metastatic sites, except for brain and peritoneum. Stabilization (S) occurred in 26 patients (28%). The remaining 42 patients (45%) showed clear progression of their metastatic disease while on therapy. The actuarial 24-month survival for the whole group was 13%, increasing to 29% in responders (CR+PR), as compared with only 10% for non-responders (S+P; P < 0.0001). Mitoxantrone was generally well tolerated; nausea, vomiting and hair loss were mild. Nine out of 625 treatment cycles resulted in leukopenic fever with uneventful recovery. All patients had serial MUGA scans; 3 patients (cumulative total doses of 200, 250 and 342 mg, respectively) developed a significant drop in the left ventricular ejection fraction. Clinical evidence of congestive heart failure was observed in one patient who had received prior doxorubicin-based adjuvant chemotherapy. Mitoxantrone seems to be as effective as other drugs given singly or in combination as second-line chemotherapy in patients with metastatic breast cancer. Its low morbidity makes its use attractive in this setting.

Ifosfamide is an oxazaphosphorine analogue of cyclophosphamide with proven activity in breast cancer but substantial urotoxicity. The introduction of mesna as a uroprotective agent provided a stimulus for reexamination of ifosfamide for therapy of women with metastatic breast cancer. Twenty women with measurable (18 patients) or evaluable (2 patients) disease were entered into a phase II clinical trial of ifosfamide plus mesna as first-line chemotherapy. Ifosfamide was administered i.v. at a dose of 1,800 mg/m2 in 1 L D5W over 2 h on five consecutive days. Mesna was administered i.v. at a dose of 400 mg/m2 over 15 min immediately before and 1 h after ifosfamide, and then every 4 h for three more doses. The last three doses could be given either i.v. or orally. The planned cycle length was 28 days. Three patients (15%), all with measurable disease, achieved a partial response (95% confidence interval: 3 to 38%). Median time to progression was 137 days and median survival was 407 days. Toxicities included cumulative myelosuppression and substantial nausea and emesis. Four patients were removed from treatment because of toxicity alone and a fifth refused further therapy. We conclude that ifosfamide, plus mesna, as given in this protocol has definite but limited antitumor activity and poor tolerability.

A phase I feasibility trial with a 5-day schedule of circadian rhythm-modulated mitoxantrone (MIT), 5-fluorouracil (5-FU, 600 mg/m2/day), and folinic acid (FA, 300 mg/m2/day) was performed in patients with metastatic breast cancer. The MIT dose was escalated from 2 to 2.5 and 2.75 mg/m2/day in consecutive groups of six patients. All three drugs were infused intravenously with a multichannel ambulatory pump. Maximal delivery rate was programmed at 4.00 hours for 5-FU and FA and at 16.00 hours for MIT. Eighteen women with advanced metastatic breast cancer were included in the trial between April 1991 and July 1993. Seventeen of 18 patients had received previous chemotherapy, which contained anthracyling for 16 of them. Tolerability of the first treatment course was assessed 10 and 21 days after course onset. Neutropenia was dose dependent and the most frequent toxicity (grade 3: 4 patients; grade 4: 7 patients), yet only a single hospitalization was required for fever and neutropenia. A single patient exhibited grade 3 mucositis. No grade 3 or 4 diarrhea, nausea, or vomiting was encountered. This chronomodulated infusion of MIT, 5-FU, and FA showed acceptable toxicity in heavily pretreated patients. For the phase II evaluation of the antitumor activity of this circadian schedule, a dose of 2.75 mg/m2/day of MIT is recommended using a monthly regimen. Further dose escalation may be performed in patients without bone metastasis and good performance status.

A late phase II clinical trial of RP56976 (docetaxel), derived from Taxus baccata was performed to evaluate anti-tumour activity, time to progression and clinical toxicity in patients with advanced or recurrent breast cancer. The patients, between 15 and 80 years old with performance status (PS) of 0-2, received at least two cycles of docetaxel 60 mg m-2 intravenously at 3-4 week intervals. Of the 81 patients enrolled, the 72 eligible for the study were given a total of 327 cycles, with a median of four cycles each. Five patients obtained a complete response (CR) and 27 a partial response (PR); the response rate (RR) was 44.4% (95% confidence interval 32.7-56.6%). A relatively high RR of 9/28 (32.1%) was observed in patients who had received prior chemotherapy involving anthracyclines. The dose-limiting toxicity was grade 3-4 leucocytopenia or neutropenia, found in 78.9% and 85.9% patients respectively. Other severe (grade > 3) toxicities included alopecia (38%), anorexia (18.3%), nausea/vomiting (11.3%), and fatigue (9.9%). Hypersensitivity reactions, oedema and skin toxicity were not severe and were reversible. One therapy-related death occurred 10 days after the initial dose was given. These findings indicate that docetaxel has potent activity against metastatic breast cancer, and that the dose of 60 mg m-2 is safe.
