Preliminary data of an ongoing phase II-study in metastatic breast cancer patients are presented. Patients with metastatic breast cancer entered the study after hormone therapy had failed; prior treatment with cyclophosphamide, methotrexate and 5-fluorouracil (CMF) was also allowed. The patients were treated with three cycles of 40 mg/m2 epirubicin i.v. on days 1-3 and 4 x 120 mg oral verapamil on days 0-3, given every 3-4 weeks. After three chemotherapy courses, ifosfamide was given as a short infusion of 3 g/m2 on days 1-3. Mesna (20% of the total ifosfamide dose) was given 0, 4 and 8 h after ifosfamide administration. Response was evaluated after three cycles of epirubicin/verapamil and after the last (third) cycle of ifosfamide. The side effects of this treatment were tolerable. The epirubicin/verapamil combination was no more toxic than epirubicin alone. Despite the high dose of verapamil, systolic blood pressure remained above 80 mm Hg, and patients never had a period of strict bed rest. Alopecia was almost complete after induction therapy with epirubicin/verapamil, and nausea and vomiting were absent or mild during epirubicin/verapamil chemotherapy and were easily controlled by antiemetics during ifosfamide treatment. Stomatitis and mucositis, the main toxic effects, could be ameliorated by intensive mouth-washing procedures. The haematological toxicity was greater after epirubicin/verapamil treatment than after ifosfamide therapy, but neither bleeding nor infections due to thrombocytopenia or leucopenia were observed.

Thirty patients with previously untreated and measurable or evaluable advanced soft tissue sarcoma entered this phase II study. Median age was 53 years (range: 24-71 years). Starting dose of Epirubicin was 100 mg/m2 IV bolus on day 1 combined with Ifosfamide, 2.5 g/m2, as a 6-hr IV infusion on day 1 and day 2 with uroprotection with Uromitexan, 1.6 g/m2, on day 1 and day 2. This schedule was repeated every 3 weeks. In case of minimal myelosuppression, the dose of Epirubicin was increased by 10 mg/m2 up to 130 mg/m2. Ifosfamide dosage was not increased. Mean cumulative dose of Epirubicin received was 477 +/- 272 mg/m2 (range: 200-1200 mg/m2). Of 27 evaluable patients (WHO criteria), 13 had a partial response (48%), 4 showed no change (15%), and 10 had progressive disease (37%). Median time to progression was 27 weeks. Of 27 patients evaluable for toxicity, hematological toxicity at day 21 was mild. Nonhematological toxicities consisted of nausea and vomiting in 82% of patients (WHO grade 3-4 = 19%), stomatitis in 44.5% (WHO grade 3 = 7.5%), and alopecia in 96% (WHO grade 2-3 = 89%). Appearance of cardiac dysfunction without heart failure during the treatment led to discontinuation of this chemotherapy in 3 patients. The results of this study show that the combination of Epirubicin and Ifosfamide is effective in advanced soft tissue sarcoma with an acceptable toxicity. However, we cannot conclude from this trial whether combination Epirubicin and Ifosfamide is superior to Epirubicin alone.

Sodium 2-mercaptoethanesulfonate reacts with the metal ions Pd(II), Pt(II), Ag(I), Cd(II) and Zn(II) to yield complexes containing multiple anionic sulfonate sites. On the basis of spectroscopic and other analytical data the complexes were assigned the tentative molecular formulas: Pd6(SCH2CH2SO3Na)12, Ptn(SCH2CH2SO3Na)2n+2, Agn(SCH2CH2SO3Na)n, Na2Zn4(SCH2CH2SO3Na)10, and Na2Cd4(SCH2CH2SO3Na)10. The complexes displayed a variety of differences in activity towards DNA and RNA viruses. The platinum complex showed no measurable cytotoxicity and exhibited a spectrum of antiviral activity resembling that of dextran sulfate. It was active against HIV-1 and HIV-2, herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2), thymidine kinase-deficient HSV-1, human cytomegalovirus, vesicular stomatitis virus (VSV), influenza A virus, respiratory syncytial virus (RSV), Sindbis virus, Junin virus and Tacaribe virus. The palladium complex also showed no measurable cytotoxicity, but was completely inactive against most viruses, with one notable exception: both HIV-1 and HIV-2 were substantially inhibited by the palladium complex. The silver complex showed significantly less antiviral activity and greater cytotoxicity than the platinum complex but did show some selectivity against RSV. The zinc complex showed only modest activity against VSV, RSV, Junin virus, and Tacaribe virus, and like the silver compound was more cytotoxic than either the platinum or palladium complex. The cadmium complex was toxic to all of the cell lines used for in vitro evaluation of antiviral activity. Based on these results, the platinum and palladium compounds appear to be promising candidates for further studies, that is, as vaginal microbicides in the prevention of genital HIV and/or HSV transmission.
