Measure
Vincristine
Induction phase: participants assigned to vincristine will receive vincristine weekly at a dose of 0.05mg/kg/dose IV (for participants less than 10kg) or a dose of 1.5 mg/m2/dose (for participants greater than 10kg) for 2 months. Maintenance: if participants continue to receive vincristine weekly for 2 months, every 2 weeks for 5 months and every 3 weeks for 5 months. Vincristine: Vincristine dose dependent upon weight. Weekly for 2 months (Induction); Weekly 2 months; every 2 weeks for next 5 months; every 3 weeks for 5 months (Maintenance)
Sirolimus
Sirolimus will be administered at a dose of 0.8mg/m2/dose twice a day on a continuous dosing schedule throughout the trial for participants randomized to Sirolimus or for participants who fail vincristine may cross-over to the sirolimus arm. Sirolimus trough levels will be maintained between 10-15 ng/ml. Sirolimus: Continuous dosing to maintain trough level of 10-15ng/ml.

PRIMARY outcome

Timeframe: 2 months

Population: no analysis was performed due to study being closed for low enrollment

Hematologic parameters are defined as a platelet count greater than 100,000/uL (or a 2 times increase in platelet count compared to baseline) and a fibrinogen level greater than 150mg/dl.

Outcome measures

Outcome data not reported

PRIMARY outcome

Timeframe: 2 months; 12 months

Population: study was closed early due to slow enrollment

Serious and non-serious adverse events will be recorded for all participants and graded using CTCAE v4.0 (Common Toxicity Criteria for Adverse Effects). Adverse event rates will be calculated for both sirolimus and vincristine.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 6 months; 12 months

Population: no analysis was performed

Disease evaluation will be measured using a combination of quality of life assessments, clinical parameters, and radiologic images.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 6 months; 12 months

Population: no data analyzed as study was closed early

Serious adverse events and adverse events will be graded according to CTCAE v4.0. Adverse event rates will be calculated for both sirolimus and vincristine.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Baseline, 2 months, 6 months, and 12 months

Population: no analysis performed as study was closed early

The following KHE biomarkers will be evaluated vascular endothelial growth factor A, C, and D (VEGF-A, C, D\_, IL-8 (interleukin), Pleiotrophin, IGF-1 (insulin-like growth factor), endothelin-1, thrombospondin and angiopoietin 1 and 2.

Outcome measures

Outcome data not reported
