Dosage and administration details |
The investigational drug treosulfan is available as dry substance in vials of 1 g and 5 g and must be dissolved in 20 ml or 100 ml of water for injection respectively. A dosage of 14 g/m² will be administered intravenously within 120 minutes on 3 consecutive days (day -6, -5, -4).
Alkalisation of the urine by infusion of sodium bicarbonate solution is not recommended because of the pH-dependent activation of treosulfan

Dosage and administration details |
The investigational drug rapamycin is available as 1 mg tablet. It will be administred as a starting dose of 4 mg die from the day before the start of the conditioning (day -7), with a target serum concentration of 8-15 ng/ml by HPLC. Levels will be monitored three times weekly during hospitalization and then as clinically indicated.
Rapamycin will be continued till day +60 unless contraindicated because of toxicity or in case of disease progression or relapse. The drug will be tapered beginning at day +60 and eliminated by day +100, unless aGvHD occurred.

End point title |
Primary - progression-free survival [1] | ||||||||
End point description |
Progression events are defined as relapse of disease in patients in CR at the moment of transplant and progressive desease in the others. Relapse is defined according to “WHO diagnostic criteria”. Progressive diseases is defined as increasing of 25% of the bulk of disease parameters (blast for leukemia, linfonodes diameters for lymphoma, monoclonal paraprotein in MM).
|
||||||||
End point type |
Primary
|
||||||||
End point timeframe |
Progression-free survival (PFS) within 1 year after transplantation is measured from time of start of HSCT (= day -7) to time of progression event.
|
||||||||
Notes [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point. Justification: This study is a non-controlled phase II study. For efficacy comparison, mainly EBMT registry data or published papers will be used. |

Adverse events information
|
|||||||||||||||||
Timeframe for reporting adverse events |
Between day -6 and day +28 the patient will be asked and examined by the investigator for the occurrence of AEs. This time period is assumed to be appropriate for the evaluation of adverse events directly related to the conditioning regimen.
