Fotemustine is a new nitrosourea which has shown some efficacy on disseminated malignant melanoma (DMM) (24.2% response rate (RR) among 153 patients in a Phase II trial) but little activity on hepatic metastasis (8.8% RR). In order to improve those poor results, hepatic intra-arterial infusion (HIAI) of fotemustine was performed. After two years, thirteen patients, all in good general condition, were evaluable. Seven were pretreated and six had extrahepatic metastasis on entry into the study. All patients had a surgically implanted intra-arterial catheter. The induction cycle consisted of 100 mg/m2/week for 3-4 weeks, followed by 5 weeks rest and maintenance therapy of 100 mg/m2 every 3 weeks for stabilized or responding patients. Two complete responses (CR) (72+ and 145+ weeks) and six partial responses (PR) (7-18.5 weeks) were observed. The hepatic RR reached 61.5%. A RR of 42.8% was registered on preexisting EHM (one CR and one PR on cerebral lesions). Nevertheless, this treatment is limited by the high progression rate of 46.1% in extrahepatic disease. Toxicity was mainly hematologic (grade III-IV), comprising 36% neutropenia and 15% thrombopenia. Hepatic intra-arterial infusion of fotemustine is efficient therapy for liver metastases of DMM, but combination schedules (IV + HIA) are warranted.

A phase II study was designed to evaluate objective response rate and toxicity of fotemustine as single-drug chemotherapy in non-small-cell lung cancer. Eighty-seven patients with unresectable non-small-cell lung cancer took part in the study. Seventy-seven were evaluable for response. Of these, 60% had received prior chemotherapy and 74% had metastatic disease. Moreover, 22 patients had central nervous system metastases (of whom 12 were evaluable for this site). Treatment consisted of fotemustine 100 mg m-2 administered on days 1 and 8 followed by a 5 week rest period. Afterwards, responding or stabilised patients received fotemustine 100 mg m-2 every 3 weeks as a maintenance therapy. Toxicity and quality of life were recorded during therapy. Thirteen patients (17%; 95% CI 9-25%) had an objective response (11% for pretreated, 26% for non-pretreated) with a median duration of 22 weeks (range 7-41 weeks). Two objective responses were observed among the 12 patients with evaluable brain metastases. No response was observed among the 14 patients with adenocarcinoma. Haematological, gastrointestinal, hepatic and renal toxicities were mild to moderate and manageable. The most frequent biological adverse reactions were delayed thrombocytopenia and neutropenia. Quality of life did not significantly decrease during the first 6 treatment weeks. Moreover, it remained stable during the study period in patients with response or stabilisation, whereas it significantly decreased in patients who experienced progression of the disease. Fotemustine is feasible for single-drug chemotherapy in non-small-cell lung cancer even though poor prognostic variables such as brain metastases are present. It can be administered on an outpatient basis and toxicity is moderate and manageable. Thus, fotemustine can be considered as a putative drug in further combinations.

Sixteen patients who after prior systemic immunotherapy had progressing disease received fotemustine (100 mg/m2) i.v. on days 1, 8, and 15 followed by a 5-week rest period. In responding or stabilized patients, maintenance therapy consisted of 100 mg/m2 fotemustine given once every 3 weeks until progression on toxicity occurred. No objective response was observed. Four patients showed stable disease (median duration: 4 months; range: 3-19). The main toxicities were neutropenia (WHO grade 3 and 4: 27%) and thrombocytopenia (WHO grade 3 and 4: 27%). Fotemustine was administered on an outpatient basis and was generally well tolerated, but in our series of patients it had no antitumour activity in metastatic renal cell carcinoma after failure of immunotherapy.

Fotemustine activity was evaluated in 26 patients, mostly pretreated, with advanced gastric cancer. Its main toxicity was haematological with grade 3-4 neutropenia in 32% and grade 3-4 thrombocytopenia in 50% of the patients, complicated by 2 toxicity-related deaths due to haemorrhage. No complete or partial responses were observed in the 26 eligible patients and median survival was only 11 weeks. Fotemustine therefore has no activity in advanced gastric cancer.

Fotemustine was investigated in 17 patients with progressive hepatic metastases from colorectal carcinoma to define the maximally tolerated dose for a daily hepatic intra-arterial infusion (HAI) schedule. Haematotoxicity was delayed, dose-dependent and related to pretreatment, with thrombo- and leucocytopenia being dose-limiting. Local side-effects at the liver were mild. Infection (WHO grade III) occurred in 1 patient due to neutropenia. Other side-effects, particularly renal, pulmonal, neurological or cardiac toxicity, mucositis and diarrhoea, hair loss or allergic reactions did not occur. Pharmacokinetic analysis indicated a short plasma half-life (t1/2 = 25.8 +/- 11.5 min) and a high body clearance (CL = 2193 +/- 870 ml/min) with large inter- and intra-individual variations. Of 15 evaluable patients, one complete and three partial responses were observed (ORR = 27%; CI95% [4.5-49.5%]). All tumour remissions appeared at higher dose levels in previously untreated patients. Considering the absence of mucosal side-effects, such as mucositis/diarrhoea and of hepatic toxicity, this agent was well tolerated. The recommended intra-arterial dose for consecutive phase II trials is 125 mg/m2/day1-3.

Fotemustine (FTM) is a common treatment option for glioblastoma patients refractory to temozolomide (TMZ). Although elderly patients represent a large component of glioblastoma population, the feasibility and the efficacy of second-line FTM are not available in those patients.We retrospectively analyzed the records of glioblastoma patients older than 65 years, receiving FTM at a dose of 70-100 mg/m(2) of FTM every week for 3 consecutive weeks (induction phase) and then every 3 weeks (70-100 mg/m(2)), as second-line treatment.Between January 2004 and December 2011, 65 glioblastoma patients (median age, 70 years; range, 65-79 years) were eligible for this analysis. Sixty-five patients received a total of 364 FTM cycles, with a median of 4 cycles for each patient. After induction, we observed 1 complete response (1.5 %), 12 partial responses (18.5 %), 18 stable diseases (27.7 %), and 34 patients' progressions (47.7 %). Disease control rate was 43.1 %. Median survival from the beginning of FTM therapy was 7.1 months, while the median progression-free survival was 4.2 months, and the 6-months progression free survival rate was 35.4 %. The most relevant grade 3-4 toxicity events were thrombocytopenia (15.3 %) and neutropenia (9.2 %). In the univariate and multivariate analysis, time from radiotherapy to FTM, number of TMZ and FTM cycles and disease control resulted independent prognostic factors.This study showed that FTM is a valuable therapeutic option for elderly glioblastoma patients, with a safe toxicity profile.
