The purpose of this study is to determine if the use of sirolimus in the treatment of children and young adults with complicated vascular anomalies will prove to be safe and provide objective response resulting in improved clinical status and quality of life.
Patients with vascular anomalies (VA) have a spectrum of diseases that can be broadly classified into vascular tumors and malformations. Complicated vascular anomalies can cause disfigurement, chronic pain, and organ dysfunction with significant morbidity and mortality. Despite the severity of potential complications, we lack uniform guidelines for the treatment and response to treatment of children and young adults with these diseases. There are pre-clinical and clinical data supporting the essential regulatory function of the PI3K/Akt/mTOR pathway in vascular growth and organization, and suggest a therapeutic target for patients with complicated vascular anomalies. The overall goal of this trial is to objectively determine the effectiveness and safety of the mTOR inhibitor Rapamycin* in the treatment of children and young adults diagnosed with complicated vascular anomalies. We propose a Phase 2 trial with the diagnostic, therapeutic and response criteria experimentally determined in this study used as a framework for future Phase 3 clinical trials.

Kaposiform hemangioendothelioma (KHE) is a rare and aggressive vascular tumor that can be associated with a consumptive coagulopathy and thrombocytopenia (Kasabach-Merritt phenomenon). Only one case o...
We sought to characterize the clinical features and management of patients diagnosed as Kaposiform hemangioendothelioma (KHE) without cutaneous involvement.
Recent reports have suggested that the topical formulation of sirolimus is effective in treating facial angiofibromas in tuberous sclerosis complex (TSC). Here, we determined the safety and efficacy o...
To evaluate the outcome and safety of corticosteroids and vincristine (VCR) in the treatment of kaposiform hemangioendothelioma (KHE) and tufted angioma (TA).
Kasabach-Merritt phenomenon (KMP) occurred uniquely in patients with kaposiform hemangioendothelioma (KHE) and tufted angioma (TA). We report the clinical characteristics of two patients with KHE invo...
A macrolide compound obtained from Streptomyces hygroscopicus that acts by selectively blocking the transcriptional activation of cytokines thereby inhibiting cytokine production. It is bioactive only when bound to IMMUNOPHILINS. Sirolimus is a potent immunosuppressant and possesses both antifungal and antineoplastic properties.
Rapidly growing vascular lesion along the midline axis of the neck, upper trunk, and extremities that is characterized by CONSUMPTION COAGULOPATHY; THROMBOCYTOPENIA; and HEMOLYTIC ANEMIA. It is often associated with infantile Kaposiform HEMANGIOENDOTHELIOMA and other vascular tumors such as tufted ANGIOMA.
A neoplasm derived from blood vessels, characterized by numerous prominent endothelial cells that occur singly, in aggregates, and as the lining of congeries of vascular tubes or channels. Hemangioendotheliomas are relatively rare and are of intermediate malignancy (between benign hemangiomas and conventional angiosarcomas). They affect men and women about equally and rarely develop in childhood. (From Stedman, 25th ed; Holland et al., Cancer Medicine, 3d ed, p1866)
A derivative of sirolimus and an inhibitor of TOR SERINE-THREONINE KINASES. It is used to prevent GRAFT REJECTION in heart and kidney transplant patients by blocking cell proliferation signals. It is also an ANTINEOPLASTIC AGENT.
