Brief Summary

Prospective, dose-escalating mono-center open label dose-finding study without control group (3+3 design), including a follow-up on-treatment observation. In this study will be recruited 15 patients with a histologically or cytologically confirmed diagnosis of an advanced malignant disease during a therapy-free interval.Investigational drug:Iscador®P: fermented aqueous extract of mistletoe grown on pine tree (Viscum album L. subspecies austriacum (Wiesb.) Vollmann), licensed for subcutaneous (SC) application in Switzerland, Germany, Austria, Sweden, and South Korea in dosages up to 20 mg.

The initial dose group of the study is set to 40 mg Iscador®P.

Detailed Description

This is a prospective open label dose finding study (phase I) of Iscador®P in patients with histological or cytological confirmed diagnosis of an advanced malignant disease during a therapy-free interval. Primary objective : To determine the maximum tolerated dose (MTD) of Iscador®P as intravenous infusion in the aforementioned patient population, based on the incidence of dose-limiting toxicities (DLTs). Secondary objective :To investigate safety and tolerability of long-term intravenous infusion of Iscador®P based on incidence and severity of adverse drug reactions.

All patients are receiving best supportive care and may receive, if necessary, specified concomitant therapies, which should not interfere with the safety parameters chosen for this study.

Investigational therapy will be administered in six Dose Groups (DG): 10 mg, 20 mg, 40 mg, 90 mg, 140 mg and 200 mg Iscador®P. The initial dose group of the study is set to 40 mg Iscador®P.

The two lower dose groups (20 or 10 mg) will only be used in case of intolerance at 40 mg Iscador®P. Once per week patients receive intravenous infusions of Iscador®P dissolved in 250 ml of sodium chloride solution (0.9 %). After the 4-week period of the MTD estimation phase each subject will immediately be included into a follow up observation in which he/she receives the last well tolerated dosage they had or the next lower dosage than the currently investigated DG in the running phase Ib study depending on the current estimate of the MTD at that time.

Study entry of individual patients will be set apart by one week. Dosages of subsequent dose groups depend on the incidence of DLTs in former groups.

For safety reasons the values of endotoxin content in Iscador®P, measured by the limulus test, are considered as the real content of endotoxins although the mistletoe lectins are cross reacting in this test. This leads to a maximum dose of 200 mg representing the upper limit of this dose finding study.

Study Groups

Iscador®P as intravenous infusion

Investigational therapy will be administered in six Dose Groups (DG):

10 mg, 20 mg, 40 mg, 90 mg, 140 mg and 200 mg Iscador®P. The initial dose group of the study is set to 40 mg Iscador®P. The two lower dose groups (20 or 10 mg) will only be used in case of intolerance at 40 mg Iscador®P. Once per week patients receive intravenous infusions of Iscador®P dissolved in 250 ml of sodium chloride solution (0.9 %). After the 4-week period of the MTD estimation phase each subject will immediately be included into a follow up observation in which he/she receives the last well tolerated dosage they had or the next lower dosage than the currently investigated DG in the running phase Ib study depending on the current estimate of the MTD at that time.
