A randomized trial was conducted to determine whether administration of Amifostine with chemotherapy for small cell lung cancer could decrease the toxicity. 84 patients with small cell lung cancer of favourable prognosis (limited disease, performance status 0-1; limited disease with performance status 2 but normal sodium and alkaline phosphatase, or extensive disease with performance status 0-1, normal sodium and alkaline phosphatase) received treatment with Ifosfamide 3 g/m(2)intravenously, Carboplatin (Glomerular filtration rate + 25) x6 mg intravenously, Etoposide 50 mg orally, twice daily, for 7 days, every 3 weeks. Patients were randomized to receive amifostine 740 mg/m(2)immediately prior to the intravenous drugs (n = 42) or to receive chemotherapy alone (n = 42). The two groups were similar with respect to baseline prognostic factors. There was no significant difference in the occurrence of grade III or IV neutropenia or thrombocytopenia between the two groups, nor in the response rate or overall survival, for which the median was 11 months in the chemotherapy only group and 14 months in the group treated with amifostine. This study has not shown a protective effect from the use of amifostine with this regimen and there does not appear to be any effect upon the efficacy of treatment.

A phase II study was performed to assess the safety and efficacy of ifosfamide and mitoxantrone in recurrent and/or metastatic squamous cell carcinomas of the head and neck. Treatment consisted of ifosfamide 1500 mg/m2 in 1000 ml saline, infused over 60 min and mesna 20% of the total dose of ifosfamide in three doses for 3 days combined with mitoxantrone 12 mg/m2 given as a short infusion on day 1. Treatment courses were repeated every 4 weeks until a total of six cycles. Twenty-two patients entered this trial, 13 of whom had received chemo- and radiation therapy, and nine patients who underwent radiation therapy with or without prior surgery. We observed no objective response, with the exception of two patients who experienced minor response (reduction of tumor size of 25%). The dose-limiting toxicity was myelosuppression with grade 3/4 leukocytopenia in seven patients (32%) and grade 3/4 neutropenia in 15 (68%). Severe organ toxicity except alopecia (91%) was not observed. Ifosfamide combined with mitoxantrone does not improve the therapeutic armentarium in recurrent squamous cell carcinoma of the head and neck.

Ifosfamide is an alkylating agent with proven efficacy in the treatment of solid tumours and malignant lymphomas. Because it causes only mild to moderate myelosuppression, ifosfamide is often used in combination regimens with other agents. Ifosfamide has been mainly used in therapy of lymphoma as a component of salvage regimens, but high-dose ifosfamide is also effective in the mobilization of peripheral stem cells for treatment of patients with relapsed or refractory lymphoma with regimens containing autologous stem cell transplantation. Based on promising data with a new combination regimen containing idarubicin, etoposide and ifosfamide (IIVP-16) in patients with poor-risk non-Hodgkin's lymphoma, we have performed a phase II study using DIZE (dexamethasone 20 mg i.v. days 1-4, idarubicin 8 mg/m2 i.v. days 1 + 2, ifosfamide 1.0 g/m2 continuous infusion (c.i.) days 1-4, and etoposide 160 mg/m2 c.i. days 1-4) in patients with relapsed or refractory Hodgkin's and non-Hodgkin's lymphoma. In 43 evaluable patients, the response rate was 58%, including 11 complete remissions (CR) and 14 partial remissions (PR). The mean duration of response was 8 months (1-30). Myelosuppression was generally mild with mean duration of neutropenia < 1000/microL of 2.5 days (range 0-18) and thrombocytopenia < 25,000/microL of 1.5 days (0-17). Thus, DIZE is an effective and safe regimen for pretreated patients with aggressive lymphoma. These results appear to compare favourably with other salvage regimens such as IMVP-16 or DHAP. In conclusion, salvage regimens containing ifosfamide can play an important role in patients who are not eligible for high-dose chemotherapies. Moreover, ifosfamide might also have a role in reducing tumour burden and selecting those patients who qualify for HDCT.

To evaluate activity and toxicity of a non platinum-based triplet including Gemcitabine, Ifosfamide and Navelbine (GIN) in advanced NSCLC. Stage IIIB/IV NSCLC patients with WHO PS < 2 and bidimensionally measurable disease entered the study. Gemcitabine 1000 mg/sqm day 1 and 1000-800 mg/sqm day 4, Ifosfamide 3 g/sqm day 1 (with Mesna), Navelbine 25 mg/sqm day 1 and 25-20 mg/sqm day 4 were administered intravenously every 3 weeks. Objective responses (ORs) were evaluated every 2 courses: a maximum of 6 courses were administered in responding patients. According to Simon's optimal two-stage design more than 18 ORs out of 54 patients were required to establish the activity of this regimen. Fifty patients entered the study. Main characteristics of the 48 evaluated patients were: median age 63 years, ECOG performance status 0 = 65%, stage IV disease 79% and non-squamous histology 71%. The total number of courses administered was 200, median per patient 4 (range 1-6). Toxicities were evaluated according to WHO criteria: neutropenia grade 3-4 occurred in 47% of the courses; thrombocytopenia grade 3-4 in 6.6%; anaemia grade 3 in 3.5%. Twelve episodes of febrile neutropenia were reported and three patients required hospital admission. No toxic death was reported. Non-haematological toxicity, including skin rash, alopecia and fatigue, were generally. Twenty-five ORs (1 complete response and 24 partial responses) were obtained for a response rate of 52% (95% CI: 37.4-66.5%). One-year survival was 46.5%. This non-platinum-based outpatient triplet showed promising activity against NSCLC with myelosuppression, in particular neutropenia, being dose-limiting. The GIN regimen may represent a valuable alternative to standard platinum-based doublets and triplets in the treatment of advanced NSCLC and further studies with this platinum-free combination are warranted.

In an attempt to develop more effective chemotherapy regimens in advanced nonsmall cell lung cancer (NSCLC), we evaluated docetaxel-ifosfamide-cisplatin (DIP) based on our previous experience with paclitaxel-ifosfamide-cisplatin. Patients with advanced NSCLC (stages III-IV), WHO-PS< or =2, no prior chemotherapy and unimpaired hematopoietic and organ function were eligible. Chemotherapy was administered in successive dose levels (DLs) and included docetaxel (80-100 mg/m2 day 1), ifosfamide (4-5 g/m2) and cisplatin (80-100 mg/m2), both divided over days 1 and 2 every 21 days. G-CSF (lenograstin) was administered from days 4-13. Fifty-five patients were accrued (phase I: 15; phase II: 40) and all are evaluable for response and toxicity: median age = 58 (40-72); PS = 1 (0-2); gender = 48 males, 7 females; stages IIIA = 8, IIIB = 19, IV = 28; and histologies were adenocarcinoma (29), squamous (20), large cell (6). Metastatic sites at diagnosis included lymph nodes (33), bone (8), liver (6), brain (6), lung nodules (9), adrenals (7) and soft tissue (1). The dose-limiting toxicity (DLT) was reached at DL4 (Docetaxel: 100 mg/m2-Ifosfamide: 5 g/m2-Cisplatin: 100 mg/m2) consisting of 2 cases of febrile neutropenia (FN), and DL3 (Docetaxel: 100 mg/m2-Ifosfamide: 5 g/m2-Cisplatin: 80 mg/m2) was considered as the maximum tolerated dose (MTD) and recommended for further phase II testing. Among evaluable patients in phase II, 31/46 (67%; CI = 54-81%) responded; 4 were complete responses, 27 partial responses, 12 with stable disease and 3 with progressive disease. The median response duration was 7 months (2-21+), median time to progression (TTP) 8 months (1-23+) and median overall survival (OS) 13 months (2-23+). The 1-year survival was 57%. Grade (Gr) 3/4 toxicities included neutropenia 39/46 with 27 developing Gr4 (< or =7 days) and 20% FN managed successfully with broad-spectrum antibiotics, thrombocytopenia Gr3 3/46-Gr4 1/46, no Gr3 neuropathy, Gr1-2 CNS toxicity in 12, no renal toxicity, 15 Gr2 myalgias, 17 Gr2 diarrhea and 10 Gr3 vomiting. In the present phase I-II study, DIP appears highly active and tolerable in advanced NSCLC in the outpatient setting. Randomized comparisons to current standard 2-drug regimens will be warranted.

Docetaxel has shown activity in the treatment of non-small-cell lung cancer (NSCLC) that has failed previous chemotherapy. Ifosfamide is an active alkylating agent used in the first-line treatment of NSCLC. We conducted a phase II study of docetaxel and ifosfamide chemotherapy in two groups (one with and one without previous paclitaxel treatment) of NSCLC patients who had failed previous chemotherapy, to assess the response and toxicity of this combination chemotherapy. Fifty patients were enrolled from June 2000 to December 2001, including 26 patients treated with paclitaxel-containing agents and 24 patients who had never been treated with paclitaxel. Treatment consisted of docetaxel 60 mg/m(2) and ifosfamide 3 g/m(2) intravenous infusion on day 1 of every 3 weeks. Two hundred and thirty-eight cycles of treatment were given, with a median of 5 cycles (range, 1-8 cycles). All patients were evaluable for toxicity profile and response rate. The major toxicity was myelosuppression. Grade 3 or 4 neutropenia occurred in 40 patients (80%) during treatment. Febrile neutropenia occurred in 7 patients (14%). Grade 3 anemia occurred in 2 patients. The majority of patients needed a decrease in the treatment dose due to grade 4 or febrile neutropenia. Interstitial pneumonitis occurred in 3 patients, leading to the death of two. Other toxicities were few and mild in severity. After two cycles of treatment, 5 patients (10%) had a partial response (95% confidence interval 1.7-18.3%), including 2 patients previously treated with paclitaxel and 3 who had not received this treatment. More patients who had been previously treated with paclitaxel suffered from progressive disease than among those who had never been treated with paclitaxel (P = 0.049). The median time to disease progression was 5 months and the median survival was 8.2 months. Median survival was 7.6 and 8.7 months, respectively, in patients with and without previous paclitaxel treatment (P = 0.56). Median survival was 8.7 and 7.6 months in patients receiving docetaxel and ifosfamide as second- and third-line chemotherapy, respectively (P = 0.327). In conclusion, docetaxel and ifosfamide salvage chemotherapy produces a relatively low response rate, low dose intensity, and higher proportion of severe neutropenia in NSCLC. Physicians should be alert to the potential of interstitial pneumonitis. Nevertheless, median survival was of a reasonable duration.

Several agents have been evaluated for the second-line treatment of patients with non-small cell lung cancer. The TAX 317 trial found that patients treated with docetaxel (Taxotere) 75 mg/m2 had significantly longer survival than those treated with best supportive care alone. In addition, symptom control was better for patients who received chemotherapy. The TAX 320 trial found that treatment with docetaxel 75 or 100 mg/m2 resulted in significantly higher response rates than treatment with vinorelbine (Navelbine) or ifosfamide (Mitoxana), and the 1-year survival rate was also significantly better for patients treated with docetaxel 75 mg/m2. A large randomized trial compared pemetrexed (LY-231514 or Alimta) 500 mg/m2 with docetaxel 75 mg/m2. Response and survival rates were similar in the two treatment arms, however, the toxicity profile of pemetrexed was superior to that of docetaxel with significantly less Grade 3/4 neutropenia and febrile neutropenia. Fewer patients in the pemetrexed arm required hospitalization. Topotecan (Hycamtin) 2.3 mg/m2/day orally for 5 days has been compared with docetaxel 75 mg/m2 in a large 800-patient study. The results of this trial are awaited. Gemcitabine (Gemzar) and irinotecan (Campto) have been evaluated both as single agents and in combination with each other and study results do not suggest that either of these drugs is superior to docetaxel or pemetrexed. The vinca alkaloid vinorelbine has proved to be inferior to docetaxel in a randomized trial. The epidermal growth factor receptor inhibitors gefitinib (ZD1839, Iressa) and erlotinib (CP-358774, OSI 774, Tarceva) have been evaluated in Phase II trials in the second- and third-line setting. Both drugs have demonstrated interesting response rates ranging from 10 to almost 20%. The results of placebo-controlled randomized trials of this family of drugs are awaited. In summary, several studies have now found a definite role for the second-line treatment of patients with non-small cell lung cancer.

Gemcitabine (G) and cisplatin (P) are active reference agents in patients with non-small-cell lung cancer (NSCLC). Ifosfamide (I) has also been approved for NSCLC treatment. This phase I trial aimed to determine the dose-limiting toxicity (DLT), maximum tolerated dose [maximum tolerated dosage (MTD)], and recommended dose (RD) of a GIP combination in patients with advanced/metastatic NSCLC. In this study, one cycle of chemotherapy combined the following: ifosfamide: 3 g/m2 fixed dose (24-hour intravenous infusion) combined with mesna, day 1; gemcitabine: starting dose 1,000 mg/m2/d, escalating by 250 mg/m2 increments, days 1 and 15; cisplatin: starting dose 80 mg/m2, subsequently 100 mg/m2, day 15; in cohorts of at least 3 patients. Cycles were repeated every 28 days and no hematopoietic growth factors were administered. DLT was evaluated after the first chemotherapy cycle. Thirty-three patients (30 men, 3 women) with stage III (14 patients)/IV (19 patients) NSCLC were treated at eight dose levels, receiving 109 cycles of chemotherapy. Neutropenia was the only DLT reported. Although the MTD was not reached at the highest tested dose level, the RD chosen corresponds to the full doses of the GP3000 doublet standard (G: 3,000 mg/m2; P: 100 mg/m2 per cycle) every 28 days. Nonhematologic toxicities were mainly grade I-II. Relative dose intensities of G, I, and P at the RD were 96%, 98%, and 96%, respectively. Sixteen of 33 patients with measurable/evaluable disease had an objective response including two complete responses. In conclusion, GIP chemotherapy is safe and appears to be active in patients with NSCLC. The RD is gemcitabine: 1,500 mg/m2 days 1 and 15; ifosfamide: 3 g/m2 day 1; cisplatin: 100 mg/m2 day 15. A confirmatory phase II study is currently under way, before a phase III trial of GIP versus GP.

To determine the maximum-tolerated dose (MTD), dose-limiting toxicities, and pharmacokinetics of topotecan administered as a 30-min intravenous (i.v.) infusion over 5 days in combination with a 1-h i.v. infusion of ifosfamide (IF) for 3 consecutive days every 3 weeks. Patients with advanced malignancies refractory to standard therapy were entered into the study. The starting dose of topotecan was 0.4 mg x m(-2) day(-1) x 5 days. Ifosfamide was administered at a fixed dose of 1.2 g x m(-2) day(-1) x 3 days. In all, 36 patients received 144 treatment courses. Owing to toxicities, the schedule of topotecan administration was reduced from 5 to 3 days. The MTD was reached at topotecan 1.2 mg x m(-2) day(-1) x 3 days with IF 1.2 g x m(-2) day(-1) x 3 days. Haematological toxicities were dose limiting. Neutropenia was the major toxicity. Thrombocytopenia and anaemia were rare. Nonhaematological toxicities were relatively mild. Partial responses were documented in three patients with ovarian cancer dosed below the MTD. Topotecan and IF did not appear to interact pharmacokinetically. The relationships between the exposure to topotecan lactone and total topotecan, and the decrease in absolute neutrophil count and the decrease in thrombocytes, were described with sigmoidal-E(max) models. The combination of 1.0 mg m(-2) day(-1) topotecan administered as a 30-min i.v. infusion daily times three with 1.2 g x m(-2) day(-1) IF administered as a 1-h i.v. infusion daily times three every 3 weeks was feasible. However, the combination schedule of topotecan and IF did result in considerable haematological toxicity and in conjunction with previously reported pronounced nonhaematological toxicities and treatment related deaths, it may be concluded that this is not a favourable combination.

A retrospective study evaluating the efficacy and tolerability of epirubicin-ifosfamide (EI) in patients with relapsed advanced ovarian cancer (ROC) after prior chemotherapy was conducted. A total of 93 patients received epirubicin (50 mg/m(2), day 1), ifosfamide (1500 or 2500 mg/m(2), days 1-3), and mesna monthly. Thirty-five percent had received one line of chemotherapy (platinum 100%, taxanes 8%); 38%, two lines; and 27%, more than two lines. Fifty-three percent received 2500 mg/m(2)/day ifosfamide and 47% received 1500 mg/m(2)/day ifosfamide. Ifosfamide was administered by continuous infusion in 12 patients. Mean number of courses was 4 (1-12). Grade 4 toxicity was 69% neutropenia and 12% thrombocytopenia. Three patients on high-dose ifosfamide as a short infusion had central nervous system dysfunction resulting in death. There were 84 assessable patients: 7 (8%), complete responses; 13 (15%), partial responses; and 20 (24%), stable disease. Median time to progression was 5 months (3 days to 36 months). The EI combination appears to be effective in ROC. However, toxicity with high-dose ifosfamide administered by short infusion is not acceptable. Tolerability can be improved using ifosfamide at 1500 mg/m(2) by continuous infusion. The combination of ifosfamide with newer anthracycline agents such as liposomal doxorubicin may be an alternative and needs further evaluation for use after first-line taxane-based chemotherapy.
