Design outcomes

Primary

MeasureTime frame
Main Objective: To evaluate treatment efficacy by time to progression according to RECIST 1.1;Secondary Objective: - To evaluate the safety and tolerability of the sirolimus and cyclophosphamide combination - To determine the median progression free survival after start of treatment till disease progression - To determine the overall survival after start of treatment till death - To evaluate the treatment efficiency by growth modulation index;Primary end point(s): Time to progression after start of treatment according to RECIST 1.1;Timepoint(s) of evaluation of this end point: Patients will be evaluated with CT-scan every 8 weeks

Secondary

MeasureTime frame
Secondary end point(s): - Translational exploratory tumour pharmacodynamic analysis - Toxicity according to CTC version 4.0 - Objective response defined as a partial or complete response occurring after start of treatment according to RECIST1.1 - Overall survival from start of treatment until death - Time to progression during sirolimus/cyclofosfamide treatment (TTP2) divided by time to progression before start of this treatment TTP1 (=growth modulation index);Timepoint(s) of evaluation of this end point: 1. every 4 weeks on outpartient clinic visit 2. every 8 weeks with CT-scan
