About this study
Official title: Sirolimus Versus Sirolimus Plus Prednisolone for Kaposiform Hemangioendothelioma With Kasabach-Merritt Syndrome
Kaposiform hemangioendothelioma (KHE) is a rare vascular neoplasm that occurs predominantly in infancy or early childhood. KHE has a nearly equal sex ratio. The annual incidence of KHE has been estimated at 0.071 per 100,000 children. KHE presents with intermediate-malignant and locally aggressive characteristics but without distant metastases.
This pilot trial studies sirolimus versus sirolimus plus pednisolone in treating patients diagnosed with kaposiform hemangioendothelioma (KHE) and Kasabach-Merritt phenomemon (KMP) that cannot be removed by surgery. The purpose of this study is to compare the efficacy and safety of orally administered sirolimus versus sirolimus plus pednisolone in the treatment of KHE associated with KMP.
Read the detailed description
Kasabach-Merritt phenomemon (KMP) is a profound thrombocytopenia resulting from intralesional platelet trapping. It is now clear that KMP occurs with KHE and tufted angioma, not with infantile or congenital hemangiomas. KMP is typically associated with more aggressive lesions and poorer outcomes. Clinically significant KMP is a severe thrombocytopenia, generally below 30× 109/L. Severe thrombocytopenia may indicate a severer tumor, a progressive tumor, partially or totally insensitive to therapy. In addition to severe, persistent thrombocytopenia characteristic of KMP, patients often manifest elevated D-dimer and low fibrinogen. Coagulopathy in addition to thrombocytopenia is associated with more aggressive presentations and may indicate current infection or inflammation. Additionally, KMP may be complicated by severe anemia due to blood sequestration and intra-lesional hemorrhaging. KHE with KMP have notably high morbidity and mortality rates, resulting predominantly from rapid tumor growth and infiltration, compression or destruction of vital structures, and hemodynamic instability.
Consensus treatment guidelines from a multidisciplinary expert panel were published in 2013. Medical treatments with corticosteroids and/or vincristine have been recommended for the management of KHE. However, first-line treatment with corticosteroids is successful in only 10-27% of all cases, and treatment with vincristine is successful in 60-70% of patients. Moreover, vincristine monotherapy has not been confirmed to provide significant benefits in critically ill patients.
Sirolimus (also known as rapamycin) is an inhibitor of the mammalian target of rapamycin (mTOR). In recent studies, sirolimus was shown to be effective in patients with complex vascular anomalies, including KHE. Our multicenter, retrospective study demonstrated that oral sirolimus is an effective and safe option for the treatment of progressive KHE. Additionally, our data emphasized that the KHE treatment regimen should be tailored to individual patients and guided by specific clinical circumstances. In cases of severe Kasabach-Merritt phenomenon (KMP), sirolimus in combination with the short-term administration of prednisolone is recommended for controlling life-threatening conditions.

What is being measured
The primary outcome is the main question the study is designed to answer.
The changes of platelet counts
Platelet counts
Measured: 2 months
The changes of fibrinogen levels
Fibrinogen levels
Measured: 2 months
The changes in KHE volume
Response to therapy was measured by volumetric magnetic resonance imaging (MRI) analyses were performed at baseline and 6 and 12 months after treatment and were independently assessed by 2 radiologists. Changes in KHE size were classified as further growth (increase of ≥10%), no change (<10% increase and <10% decrease), partial involution (decrease of ≥10% and <75%), nearly complete involution (decrease of ≥75% and <100%), or complete involution (100%).
Photographs of the mixed KHE were taken at months 0, 6 and 12 by a medical photographer.
Measured: 6 and 12 months
The changes in the patient's symptoms and/or complications.
Improvement in the range of motion.
Measured: 6 and 12 months
Secondary outcomes (4)
Frequency of adverse events
Frequency of adverse events (e.g. gastrointestinal disorders, blood and lymphatic system disorders, metabolic disorders or other abnormal laboratory results, skin disorders and general disorders, etc.) collected by investigator and reported by parents. All adverse events were collected and graded according to Common Terminology Criteria for Adverse Events, version 4.0 (CTCAE v4.0). The causality of the adverse event was determined by the multidisciplinary staff and was classified as definitively not related, probably not related, possibly related, probably related, or definitively related. Any dose reductions, interruptions, or cessations enacted at the discretion of the investigators were recorded.
Measured: 12 months
Change in blood biomarkers
Change in vascular endothelial growth factor (VEGF-A, C and D), IL-6, IL-8, angiopoietin 1 and 2. These parameters were measured via a series of correlative laboratory studies using blood samples.
Measured: 6 and 12 months
Quality of life (QOL) in patients.
Pediatric Quality of Life Inventory (PedsQLTM) 4.0 Genetic Core Infant Scales (<2 years) or Pediatric Quality of Life Inventory (PedsQLTM) 4.0 Genetic Core Scales (2-18 years) were used.
Measured: 12 months
Measuring the impact of KHE on family functioning.
PedsQLTM 4.0 Family Impact Module (FIM) was used.
Measured: 12 months

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Sirolimus and Prednisolone in people with Kaposiform Hemangioendothelioma and Kasabach Merritt Phenomenon, run by West China Hospital at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 15 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 21 Apr 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The changes of platelet counts (time frame: 2 months). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03188068, which also lists 6 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Apr 2022.
