Patients must abstain from donating blood, semen, or sperm during participation in the study until 3 months after the end of participation in the study
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To assess the effect of sirolimus to reduce the size of defined target lesions in patients with segmental overgrowth syndromes.;Secondary Objective: To evaluate changes in disfigurement assessed by serial digital photograph To evaluate changes in health-related Quality of Life To evaluate changes in pain To evaluate changes in neuropsychological testing compared to baseline values. To evaluate changes in biomarkers compared to respective baseline values. To assess the inhibition of the mTOR pathway. Assessment of safety. Study drug compliance. ;Primary end point(s): Best response: Complete Remission (CR), or Partial Remission (PR) until 6 months after start of therapy period (baseline) measured by MRI according to response criteria;Timepoint(s) of evaluation of this end point: until 6 months after baseline | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Morphological changes in disfigurement compared to baseline by using a scale for external validation documented by photography after 3, 6 and 9 months of therapy Changes in Quality of life after 3, 6 and 9 months of therapy compared to baseline (for patients = 4 and = 17 years of age by KINDL® parents and Kiddy-KINDL® Kids 4-6 years, Kid-KINDL® Kids 7-13 years, Kiddo-KINDL® Teenager 14-17 years, and for patients = 18 by WHOQOL-BREF as well as Lansky (<16 years)/Karnofsky scale) Changes in pain after 3, 6 and 9 months of therapy compared to baseline by visual pain scales for adults and children Changes in neuropsychological tests (using Strengths and Difficulties Questionnaire (SDQ) Kids (6-11 years), Parents and Erwachsene = 18 years after 3, 6 and 6 9 months of therapy compared to baseline. Changes in IGFBP-3, IGF-1, VEGF compared to baseline values after 3, 6 and 6 9 months of therapyafter start of study treatment (baseline). Inhibition of mTOR in PBMCs assessed by immunoblotting after 3, 6 and 9 months after start of study treatment (baseline). Safety will be determined by observation of any adverse or serious adverse events. Evaluations will include clinical and laboratory assessments performed at the time points described in the flow chart. Criteria for assessment of safety will be based on standard criteria for monitoring, assessing, and reporting of adverse events (CTCAE criteria v. 5.0). Study drug compliance measured with patient diary. ;Timepoint(s) of evaluation of this end point: CR or PR after 6 months Changes in Quality of life after 3, 6 and 9 months. Changes in pain after 3, 6 and 9 months. Changes in neuropsychological tests after 3, 6 and 9 months. Morphological changes after 3, 6 and 9 months. Changes in IGFBP-3, IGF, VEGF after 3, 6 and 9 months. Inhibition of mTOR in PBMCs after after 3, 6 and 9 months. | — |
