Phase II evaluation of vindesine in the treatment of colorectal and esophageal tumors

Summary A phase II study of vindesine was carried out in 33 patients with colorectal cancer and nine patients with esophageal cancer. With the exception of six previously untreated patients with esophageal cancer, all others were refractory to 5-FU-containing regimens, which included vincristine in ten patients. The initial dose of vindesine was 4 mg/m² administered intravenously over 30 min every 2 weeks. Tumor regression >50% was seen in three patients (two colorectal and one esophageal) and an additional eight patients (six colorectal and two esophageal) achieved minor responses. Prior treatment with vincristine did not seem to influence response to vindensine. In general, the treatment with vindesine was well tolerated. The hematologic toxicity was acceptable and manifested mainly as moderate and transient neutropenia. The major nonhematologic toxicity was peripheral neuropathy, which became limiting. It occurred in 33% of patients who received two or more courses of vindesine. Because of the apparent antitumor activity and doselimiting neurotoxicity of vindesine in this study, further investigations of this compound should be conducted in combination chemotherapy programs for patients with metastatic gastrointestinal cancers.     

Vindesine in the treatment of squamous cell carcinoma (WHO I), adenocarcinoma (WHO III), and large cell carcinoma (WHO IV) of the lung

The antineoplastic activity of vindesine was evaluated in 57 patients with non-small-cell carcinoma of the lung, 53 patients were fully evaluable for response and toxicity. Twenty-seven patients had squamous cell carcinoma (WHO I), 14 had adenocarcinoma (WHO III), and 12 had large cell carcinoma (WHO IV). Forty percent of patients were previously treated. Vindesine was administered at a weekly i.v. dose of 3 mg/m2. Partial remissions were observed in 2 of 12 patients with large cell carcinoma and in 1 of 27 patients with squamous cell carcinoma. Among 14 patients with adenocarcinoma, 3 minor responses were observed. Drug-related toxic effects (mainly leukopenia with manageable and reversible neurotoxicity) required modification of dose in 41% of patients: this finding and previous treatment may have adversely affected the response rate. It is concluded that vindesine as a single agent has some activity in large cell carcinoma. Activity in the other histologic types was minimal but not totally absent and deserves further evaluation, possibly in non-pretreated patients.     

Phase II study of vindesine in patients with non-small cell lung cancer

A phase II study of vindesine (VDS) was carried out in 21 patients with non-small cell lung cancer (NSCLC). There were 13 and 8 patients with and without prior chemotherapy, respectively. VDS was administered at a weekly iv dose of 3 mg/m2. Partial response was observed in two of 15 adenocarcinomas and one of 2 adenosquamous cell carcinomas, and the overall response rate was 14.3% (3/21). Myelosuppression, especially leukopenia, was the most common dose-limiting side effect. Neurotoxicity was also a common side effect but the degree was mild. It was concluded that VDS at a dose of 3 mg/m2 every week seems to be active against NSCLC.     

An early phase II trial combining cisplatin, carboplatin and vindesine in patients with inoperable non-small cell lung cancer

We conducted an early phase II trial of advanced non-small cell lung cancer (NSCLC) to evaluate the response efficacy of a combination of cisplatin (CDDP), carboplatin (CBDCA) and vindesine (VDS). The twenty-four patients in the study had had no previous treatment. CDDP (15 mg/m2), CBDCA (200 mg/m2) and VDS (3 mg/m2) were administered on Day 1, CDDP (15 mg/m2) was administered on Days 2-5, and VDS (3 mg/m2) was administered on Day 8. We observed 9 partial responses (PR), with a total response rate of 39%. The overall median survival was 72 weeks, and the 1-year survival rate was 57%. Major toxicities were hematologic; leukopenia of grades 3 and 4 occurred in 25% patients, and thrombocytopenia occurred in 21%. Therefore, the combination of CBDCA with CDDP and VDS chemotherapy was effective against inoperable NSCLC with tolerable toxicities and a favorable median survival time.     

Chemotherapy versus chemoimmunotherapy (CAF v CAFVP v CMF each +/- MER) for metastatic carcinoma of the breast: a CALGB study. Cancer and Leukemia Group B

Three combination chemotherapy regimens each with or without the methanol-extracted residue of bacillus Calmette-Guérin (BCG) (MER) were compared for efficacy. After stratification for disease-free interval and dominant sites of disease, patients were randomized to either CMF (cyclophosphamide [CYC], 100 mg/m2 orally, days 1 through 14; methotrexate [MTX], 40 mg intravenously [IV], days 1 and 8; 5-fluorouracil [5-FU], 500 mg/m2 IV, days 1 and 8), or CAF (CYC, 100 mg/m2 orally, days 1 through 14; doxorubicin [DOX], 25 mg/m2 IV, days 1 and 8; 5-FU, 500 mg/m2 IV, days 1 and 8), or CAFVP (CAF as above plus vincristine [VCR], 1.0 mg/m2 IV, days 1 and 8; and prednisone [PRED], 40 mg/m2 orally, days 1 through 14). Nonspecific immunotherapy with MER was administered in five sites at 100 micrograms or at the lowest tenfold dilution that produced a 1-cm indurated lesion. A total of 432 patients were entered, but 37 were disqualified, leaving 395 evaluable for treatment results and toxicities. One hundred thirty-five evaluable patients were randomized to chemoimmunotherapy until October 28, 1978. One hundred twenty-six evaluable patients were randomized to chemotherapy alone in the same time period. For the entire study, a total of 260 evaluable patients were randomized to chemotherapy. Chemoimmunotherapy patients were compared with the initial 126 chemotherapy patients. Chemotherapy regimens were compared among all 260 patients. Patient characteristics were similar between regimens and between chemotherapy and chemoimmunotherapy treatment groups. For patients on chemotherapy plus MER, there was no significant differences between the regimens for response frequencies: 43%, 41%, and 32%, respectively for CMF, CAF, and CAFVP. The comparable chemotherapy alone group had 36%, 58%, and 63% response, respectively. The response rates, adjusted for chemotherapy regimen, were 52% and 38% (P = .02) for chemotherapy and chemoimmunotherapy, respectively. MER was associated with painful ulcers and fevers. Thus, MER produced toxicity without response or survival benefit and further randomization after October 28, 1978 was to chemotherapy alone. For 260 evaluable patients on chemotherapy alone, the complete (CR) and partial responses (PR) were 37%, 55%, and 58%, respectively for CMF, CAF, and CAFVP. These response rates for CAF and CAFVP were significantly better than CMF (P = .01 and P less than .01, respectively). These comparisons were consistent within subgroupings such as dominant sites of disease.(ABSTRACT TRUNCATED AT 400 WORDS)     

Inefficacy of vindesine monotherapy in advanced stage IV malignant melanoma patients previously treated with other chemotherapeutic agents

The anti-melanoma activity of vindesine as a single or polychemotherapeutic agent has been reported previously in adjuvant and first-line melanoma treatment. In this study, we investigated the usefulness of vindesine monotherapy as salvage therapy in stage IV melanoma patients after failure of other chemotherapies. Thirteen patients with progressive disease were treated with 3 mg/m2 vindesine every 2 weeks (median age, 61 years). Previous systemic treatment consisted of polychemotherapy or combined chemo-immunotherapy. All 13 patients suffered from visceral metastases (three lung, one liver, one adrenal gland and eight multiple visceral metastases). A median of three vindesine treatments was administered. Despite the various pre-treatments, the toxicity of vindesine was mild. In all 13 patients, vindesine treatment was stopped due to disease progression. The median survival after primary tumour diagnosis was 42 months (8-151 months), the survival after entering stage IV was 11 months (3-35 months), and the survival after starting vindesine therapy was 4 months (1-22 months). We conclude that vindesine monotherapy is ineffective in stage IV melanoma patients previously treated with other chemotherapeutic agents.     

Vindesine,prednisone, and daunomycin in acute lymphoblastic leukemia in relapse

Patients with resistant or recurrent acute lymphoblastic leukemia were treated with vindesine 3 mg/m2/IV weekly X 4, daunomycin 25 mg/m2/IV weekly X 4, and prednisone 40 mg/m2/PO daily X 28. Seventeen (44%) of 38 evaluable patients achieved complete remission. Fifty-one percent of 31 patients in first relapse achieved complete remission, while only one of five in second or third relapse and neither of two resistant to first induction achieved complete remission. The major toxicity was hematologic. The median duration of complete remission was only 6 weeks and median survival from start of the study, 3 months, with 22% patients remaining alive at 10 months. We conclude that the vindesine, prednisone, and daunomycin combination is no more effective than vincristine, prednisone, and daunomycin in achieving remission of relapsed acute lymphoblastic leukemia patients, and is more toxic than the latter regimen.     

A randomized study of two vindesine plus cisplatin-containing regimens with the addition of mitomycin C or ifosfamide in patients with advanced non-small cell lung cancer

The current trial was carried out to assess the survival enhancement achieved, if any, by adding ifosfamide to vindesine and cisplatin (IVP) in contrast to mitomycin plus vindesine and cisplatin (MVP). Between June 1986 and September 1988, 110 patients were randomly allocated to receive either ifosfamide (3 g/m2 plus 3 g/m2 of mesna) or mitomycin 8 mg/m2, on days 1, 29, and 71 only. In both arms vindesine was given 3 mg/m2 weekly X 5 then every 2 weeks. In the MVP arm, 120 mg/m2 of cisplatin was administered on days 1 and 29 and then every 6 weeks, whereas in the IVP arm 100 mg/m2 of cisplatin was given on the same time schedule. One hundred three patients were evaluable for response and toxicity and 56% of patients had Mountain's Stage IV disease. The response rate was 26% (14/53 patients) in the MVP arm (95% confidence interval, 14%-39%) and 20% (ten of 50 patients) in the IVP arm (95% confidence interval, 10%-34%). Neither the response rate nor the median survival times were significantly different, although more nephrotoxicity was produced in the MVP arm, grade 1+ in 43% versus 26% in IVP arm (P = 0.04). Results obtained from this study fail to demonstrate that mitomycin or ifosfamide have a synergistic effect on the efficacy of the vindesine/cisplatin combination.     

Adjuvant treatment with vindesine in comparison to observation alone in patients with metastasized melanoma after complete metastasectomy: a randomized multicenter trial of the German Dermatologic Cooperative Oncology Group

To evaluate the efficacy and safety of vindesine in patients with metastatic melanoma after complete metastasectomy. One hundred and forty-two patients with metastatic spread to regional sites, lymph nodes, and distant sites after complete metastasectomy were randomized to receive either treatment with vindesine for 2 years or observation alone. Vindesine 3 mg/m intravenously was administered biweekly for the first 26 weeks following 3-week intervals for an additional 26 weeks and thereafter every 4 weeks for 52 weeks. One hundred and thirty-nine patients were eligible for intent-to-treat analysis. Median follow-up time was 46 months. Median recurrence free survival was 7.9 months in the vindesine group and 7.6 months in the observational group (P=0.40). Three-year overall survival rate was 54.9% (37 patients) for patients receiving vindesine in comparison to 43.6% (31 patients) in the observation arm (P=0.07). No grade IV toxicity was observed. The two major side effects in the vindesine group were alopecia and peripheral neuropathy. Ten patients went off treatment because of grade III toxicity. Adjuvant treatment with vindesine did not significantly prolong disease free or overall survival in high-risk melanoma patients. Thus, this randomized trial did not confirm earlier reports of beneficial effects of adjuvant vindesine and can therefore not be recommended.     

Alternating multiagent chemotherapy for advanced ovarian cancer

A chemotherapy regimen consisting of hexamethylmelamine (H) 150 mg/m2 orally days 1-14, cyclophosphamide (C) 500 mg/m2 IV day 1 of a 28-day cycle with Adriamycin (A) 40 mg/m2 IV day 1 alternating with cis-diamminechloroplatinum (C-P) 50 mg/m2 IV day 1 every other cycle was administered to 29 patients with advanced epithelial ovarian cancer. Toxicity to this regimen included alopecia, nausea, and vomiting in all patients. Mild paresthesias occurred in four patients. Hematologic toxicity required only minimal dose modification. There was no cardiac, renal, or auditory toxicity. The clinical response rate of 55% and median survival of 14 months compare favorably with that of other reported series. This chemotherapy regimen seems to be well tolerated without jeopardizing the patients' response.     

Survival advantage for carboplatin substituting cisplatin in combination with vindesine and mitomycin C for stage IIIB and IV squamous-cell bronchogenic carcinoma: a randomized phase III study

This communication represents the definitive report of a randomized phase III study comparing cisplatin and carboplatin, in combination with vindesine and mitomycin C in stage IIIB and IV squamous-cell bronchogenic carcinoma. A total of 221 patients entered the study and were randomized into two arms. Of these, 114 patients (109 evaluable for activity) were randomized to arm A, receiving cisplatin 120 mg/m(2), mitomycin C 8 mg/m(2) and vindesine 3 mg/m(2) per cycle; 107 patients (101 evaluable for activity) were randomized to arm B receiving carboplatin 500 mg/m(2) with the same doses of mitomycin C and vindesine per cycle. Patients with progressive disease (PD) were excluded from the study after the 2nd cycle, and those with stable disease (SD), partial response (PR) and complete response (CR) received six cycles of chemotherapy (or less in case of early progression). Patients were stratified according to the clinical stage (IIIB vs. IV), performance status (0+1 vs. 2+3) and tumor histological grade (I+II vs. III). In the cisplatin arm two patients (1.9%) achieved a CR, 38 (34.9%) a PR, 45 (41.2%) a SD and 24 (22.0%) had PD; the overall response rate was 40/109 (36.8%). In the carboplatin arm five patients (5.0%) achieved a CR, 31 (30.7%) a PR, 40 (39.6%) a SD, and 25 (24.7%) had PD; the overall response rate was 36/101 (35.7%). No statistically significant difference in response rate was present between the two arms, and the response rate was not influenced by performance status, histological grade or clinical stage. The Kaplan-Meyers curves displayed a significant advantage both for time to progression (P=0.005) and overall survival (P=0.008) for patients in the carboplatin arm. The advantage for patients receiving carboplatin instead of cisplatin appeared evident in univariate setting for patients with a good performance status and clinical stage IV, and occurred irrespectively of tumor histological grade; response duration and survival of responders was identical in the two arms. Patients achieving a stable disease survived longer in the carboplatin than in the cisplatin arm (P=0.012). Thus, substitution of cisplatin by carboplatin in the combination chemotherapy regimen, although more hematologically toxic (but less emetogenic) resulted in a similar response rate, but a significantly longer time to progression and overall survival.     

Phase I study of oral menogaril administered daily for 14 consecutive days.

Twenty-eight patients were treated with oral menogaril daily x 14 every 4 weeks. Granulocytopenia was dose-limiting at 50-60 mg/m2 per day. Neutropenic fever occurred in one patient. Thrombocytopenia occurred in 3 of 6 patients treated with menogaril 60 mg/m2/day. Nausea and vomiting and other toxic effects were generally mild. No cardiac toxicity was seen. One partial remission and three minor responses were noted among 11 previously treated patients with carcinoma of the bladder. One minor response was noted among 3 patients with colorectal cancer. The dose recommended for phase II studies is 50 mg/m2 per day for 14 days. Phase II studies are recommended in carcinoma of the bladder. Gastrointestinal toxicity is substantially less on this schedule than with oral menogaril administered on a weekly or q4wk schedule, but thrombocytopenia may be more common.     

Combination chemoendocrine therapy containing vindesine for refractory metastatic breast cancer

Metastatic breast cancer has ultimately failed to respond to the multiple prior therapies, and thus new therapeutic regimens are required. Nine patients with metastatic breast cancer previously treated with multiple therapeutic regimens were enrolled. The treatment schedule was as follows: vindesine was given intravenously at a dose of 2 mg/m(2) every four weeks. Etoposide and medroxyprogesterone acetate was orally administered at a dose of 25 mg/day for 14 consecutive days and 600 mg/day every day. Only one patient with exclusive bone metastasis showed partial response and the objective response rate for the combination of agents was 11%. Pain derived from the metastatic lesions was reduced in four (80%) among five patients with bone metastasis. For patients with refractory breast cancer, especially with bone metastasis, chemoendocrine therapy containing vindesine might have therapeutic efficacy with low toxicity and favorable quality of life.     

Phase III randomized trial of docetaxel plus cisplatin versus vindesine plus cisplatin in patients with stage IV non-small-cell lung cancer: the Japanese Taxotere Lung Cancer Study Group.

PURPOSE: Few randomized trials have demonstrated survival benefit of combination chemotherapy involving new agents plus cisplatin compared with classic combination chemotherapy in advanced non-small-cell lung cancer (NSCLC). The primary aim of this study was to test whether docetaxel plus cisplatin (DC) improves survival compared with vindesine plus cisplatin (VdsC) in patients with previously untreated stage IV NSCLC. PATIENTS AND METHODS: Eligible, stage IV, chemotherapy-naive patients (n = 311) were randomly assigned to receive docetaxel 60 mg/m(2) intravenously on day 1 plus cisplatin 80 mg/m(2) intravenously on day 1 of a 3- or 4-week cycle, or vindesine 3 mg/m(2) intravenously on days 1, 8, and 15 plus cisplatin 80 mg/m(2) intravenously on day 1 of a 4-week cycle. Cross-over administration of docetaxel and vindesine was prohibited for both treatment groups. RESULTS: Overall, 302 patients were eligible for evaluation. The DC arm demonstrated significant improvements compared with the VdsC arm in overall response rates (37% v 21%, respectively; P <.01) and median survival times (11.3 v 9.6 months, respectively; P =.014). Two-year survival rates were 24% for the DC arm compared with 12% for the VdsC arm. The physical domain of the Quality of Life for Cancer Patients Treated with Anticancer Drugs measure was significantly better in the DC arm than in the VdsC arm (P =.020). Toxicity was predominantly hematologic and was more severe in the VdsC arm. CONCLUSION: As first-line treatment for stage IV NSCLC, DC resulted in greater clinical benefit in terms of response rate (with marked improvements in overall and 2-year survival rates) and quality of life than did treatment with VdsC.     

A Phase I Trial of Combination Chemotherapy Employing Carboplatin, Vinca Alkaloids, with or without Bleomycin in Patients with Advanced Malignant Tumors

A Phase I trial of three carboplatin-based combination chemotherapy regimens was conducted. These included: carboplatin plus vindesine; carboplatin, vindesine, plus bleomycin; and, carboplatin plus vinblastine. Carboplatin was administered every 28 days as an intravenous bolus. The initial dose was 150 mg/m² and doses were escalated by 50 mg/m² in each successive group of patients. Vindesine was given at a dose of 3 mg/m² weekly for 5 doses, then every other week thereafter. Bleomycin, 10 units/m² IV bolus, was followed by 10 units/m²/day infusion for 4 days (3-7 and 31-35). Vinblastine was given at 5 mg/m² every other week. Doses of vindesine, vinblastine, and bleomycin were not escalated. The maximum tolerated dose (MTD) of the carboplatin, vindesine bleomycin regimens was reached at a carboplatin dose of 250 mg/m² and the MTD was influenced by the weekly vindesine in the initial 4 weeks of therapy. The MTD of the carboplatin and vinblastine regimen was reached at a carboplatin dose of 500 mg/m². Dose-limiting toxicity of all three regimens was leukopenia. Although nonhematological toxicity of the carboplatin and vinblastine regimen included peripheral neuropathy and emesis, therapy was easily administered in an outpatient setting. The recommended Phase II dose of carboplatin is 450 mg/m² in combination with vinblasrine at this dose and schedule for previously untreated patients. Twelve patients demonstrated major responses with the various regimens including 5 of 24 patients with adenocarcinoma of the upper gastrointestinal tract.     

Cisplatin and vindesine combination chemotherapy for non-small cell lung cancer: a randomized trial comparing two dosages of cisplatin

Forty-five patients with advanced non-small cell lung cancer were randomly allocated to receive vindesine (3 mg/m2 every week) plus either high-dose cisplatin (120 mg/m2 every 4 weeks) or low-dose cisplatin (80 mg/m2 every 3 weeks). All patients were previously untreated. The response rate for the high-dose regimen of cisplatin was 39% (9/23) and that for the low-dose regimen of cisplatin was 33% (7/21); the difference was not statistically significant. Only one patient treated with high-dose cisplatin achieved complete response, lasting 6.5 months. The median duration of response was 5.6 months (range, 2.7-7.7) in the high-dose cisplatin group and 6.8 months (range, 1.9-8.9) in the low-dose cisplatin group. The median survival times for the 23 patients treated with the high-dose regimen of cisplatin and for the 21 patients treated with the low-dose regimen of cisplatin were 9.0 and 10.8 months, respectively. Significantly more azotemia occurred in the high-dose cisplatin group than in the low-dose cisplatin group (P less than 0.05). Combination chemotherapy with cisplatin and vindesine showed significant antitumor activity in patients with non-small cell lung cancer. However, the high-dose regimen of cisplatin did not result in a significantly better response rate or survival advantage, and was associated with greater toxicity.     

A randomized phase I and II study of short-term infusion of high-dose fluorouracil with or without N-(phosphonacetyl)-L-aspartic acid in patients with advanced pancreatic and colorectal cancers

Fifty-two patients with advanced gastrointestinal (GI) malignancies who had not received previous chemotherapy or radiation therapy were randomized to be treated either with 24-hour infusion of weekly fluorouracil (5-FU) or the same plus N-(phosphonacetyl)-L-aspartic acid (PALA). Forty-seven patients were evaluable for the assessment of toxicity and antitumor activity. PALA was administered as an intravenous (IV) bolus over 15 minutes at a fixed dose, 250 mg/m2. The latter agent was administered 24 hours before the start of 5-FU infusion. 5-FU was initially administered at 750 mg/m2 and was incrementally increased to 3,400 mg/m2. In both arms of the randomized study, the courses were repeated every week. In both arms of the study, ataxia and myelosuppression were the dose-limiting toxic effects. At 5-FU dose of 3,400 mg/m2, one patient in each arm developed grade 3 hematologic toxicity. Other reversible side effects included grade 2 skin changes, nausea, and vomiting. During the administration of 2,600 mg/m2 of 5-FU over 24 hours, the steady state plasma 5-FU concentration was approximately 20 mumol/L. The maximum tolerated dose (MTD) for 5-FU for protracted treatment is 2,600 mg/m2 in either arm of the study. Therapeutic response was predominantly seen in the combination arm: there were two patients with complete response (CR) and 11 patients with partial response (PR) of 28 patients in the study. In the 5-FU alone arm there were four PR and 19 patients in the study.     

Multi-institutional phase II randomized trial of integrated therapy with cisplatin, dacarbazine, vindesine, subcutaneous interleukin-2, interferon alpha2a and tamoxifen in metastatic melanoma. BREMIM (Biological Response Modifiers in Melanoma)

The aim of this study was to evaluate the toxicity and efficacy of a monochemotherapy regimen of dacarbazine (DTIC), tamoxifen , interferon-alpha2a and interleukin-2 (IL-2) and two polychemotherapy regimens of cisplatin, DTIC, vindesine, tamoxifen, interferon-alpha2a with or without IL-2 in patients with metastatic melanoma. Consecutive patients with metastatic melanoma were enrolled in this trial and were randomized to arm A, consisting of DTIC 800 mg/m2 every 21 days, IL-2 9 MIU subcutaneously days 1-5 and 8-12, arm B, consisting of cisplatin 30 mg/m2 days 1-3, DTIC 250 mg/m2 days 1-3 and vindesine 2.5 mg/m2 day 1 every 28 days (CVD), or arm C, consisting of CVD plus IL-2 6 MIU days 1-5 and 8-12 every 28 days. In all three arms Interferon 3 MU subcutaneously three times a week and tamoxifen 20 mg orally were given throughout. Ninety-two patients were included in this study. Patient characteristics in the three groups were well balanced. The three regimens were delivered on an outpatient basis without major toxicity. The toxicities that did occur consisted primarily of flu-like symptoms in the IL-2 arms (A and C) and haematological toxicities in the CVD arms (B and C). No grade IV toxicities were encountered and no treatment-related deaths occurred. The total response rate was 13% in arm A, 35% in arm B and 37% in arm C. The median duration of response was 6 months and the median survival was 11 months. According to this phase II randomized trial polychemoimmunotherapy with CVD has an objective response rate of 35-36%, while monochemoimmunotherapy with DTIC has a response rate of 13%.     

Vindesine in the treatment of breast cancer

Summary A phase-II study of vindesine was carried out in 23 patients with histologically proven advanced breast carcinoma. Toxicity was assessed in a further 24 patients with several different tumour tupes. Treatment was given in a starting dose of 3 mg/m² weekly by IV bolus, increasing by 1 mg weekly as toxicity allowed. The response rate in 21 evaluable patients with breast carcinoma was 29%. In 47 patients evaluable for toxicity, leukopaenia occurred in 45% and was doserelated; thrombocytopaenia was rare (4%); neurotoxicity occurred in 40%; constipation in 17%, alopoecia in 46% and an influenza-like syndrome in 21%.It was concluded that vindesine was a clinically active agent in breast carcinoma, with a spectrum of toxicity lying between those of vincristine and vinblastine.     

The role of vindesine and lonidamine in the treatment of elderly patients with advanced non-small cell lung cancer: a phase III randomized FONICAP trial. Italian Lung Cancer Task Force.

AIMS: To evaluate the efficacy and treatment compliance in elderly patients with advanced non-small cell lung cancer (NSCLC) of two chemotherapeutic agents with mild toxicity, 153 previously untreated patients aged over 70 years were randomized to receive lonidamine (450 mg daily p.o. until progression), vindesine (3 mg/m2/daily i.v. weekly for 4 weeks and then every 2 weeks until progression), the combination of the two drugs at the same dose and schedule, or supportive therapy only in a four-arm factorial randomized trial. METHODS: 126 patients were included in the final analysis. Their median age was 75 years. Forty percent had stage IV disease and 60% stage III. Most patients were males (85%) and the majority had squamous histology (68%). RESULTS: Among 104 patients evaluable for response there were only 3 PRs (1/30 in the lonidamine arm and 2/33 in the lonidamine + vindesine arm). Overall, 8.7% and 9.5% of the patients, respectively, progressed or died early, before response evaluation; another 9.4% refused treatment continuation because of poor compliance with the study protocol. Eighty-five patients were fully evaluable for toxicity, which was generally mild. Leukopenia grade 1-3 was found in less than 30% of patients treated with vindesine or vindesine + lonidamine. The most common complaints associated with lonidamine treatment were myalgia (70% of patients), fatigue (55% and 83% of patients treated with lonidamine or lonidamine + vindesine, respectively) and testicular pain in nearly 40% of cases. The overall median survival was 170 days, with no significant impact on survival of either lonidamine or vindesine. CONCLUSIONS: The low response rate and survival together with the poor treatment compliance, even in the presence of mild toxicity, do not support the usefulness of these "gentle" chemotherapies in elderly NSCLC patients. The standard management of advanced NSCLC in elderly patients remains to be defined. Specifically designed studies to address this issue are warranted.
