About this study
Official title: Guided Discontinuation Versus Maintenance Treatment of Sirolimus in Pediatric Patients With Kaposiform Hemangioendothelioma: a Randomized Controlled Trial
This randomized controlled trial aims to compare guided discontinuation with maintenance treatment of sirolimus in pediatric patients with KHE.
Read the detailed description
Kaposiform Hemangioendothelioma (KHE) is a rare vascular tumor that occurs in infants and children. KHE is characterized by sheets of spindle cells with an infiltrative pattern in the dermis, subcutaneous fat, and muscle. It is locally aggressive and can cause Kasabach-Merritt phenomenon, a serious life-threatening coagulopathy characterized by profound thrombocytopenia and hypofibrinogenemia. Sirolimus, one of the mTOR inhibitors, has become a new and very effective treatment, which is especially reliable for KHE with KMP and has acceptable side effects. However, there is yet no strong evidence on the best practice of treatment length of sirolimus. This randomized controlled trial aims to compare guided discontinuation with maintenance treatment in pediatric patients with KHE in order to provide a basis for the optimal treatment duration of sirolimus, as well as the clinical characteristics of pediatric patients who can safely reduce the dose till withdrawal.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
SirolimusDrug
Also called Rapamycin
After at least 2 years of remission of KHE, we compare guided discontinuation with maintenance treatment in pediatric patients with KHE.
| Study group | Role | What they receive |
|---|---|---|
| Maintenance treatment group | Active comparator | After at least 2 years of remission of KHE, the participant receives sirolimus as usual. The serum concentration is supposed to be 5-7 ng/ml. If the effect or side effects of sirolimus require discontinuation, it is allowed to modify intervention, and if so, the patient stays in the maintenance group. Receives: Drug: Sirolimus |
| Guided discontinuation group | Experimental | After at least 2 years of remission of KHE, the discontinuation measurement should be guided by the clinician with the following principles:
1. 10% monthly reduction of the previous dose at most.
2. At least 5 half-lives between each reduction (2 weeks).
3. Blood concentration should be monitored monthly. Adjustment can be suggested according to the linear relationship between the dose and the blood concentration.
4. At least 6 months for the duration of guided discontinuation.
5. Regular assessments and evaluations should be done.
If the condition relapses or worsens during this process, dose of sirolimus should be adjusted to the previously effective dose. After a 3-month stabilization phase, 5% monthly reduction of the previous dose could be considered. Receives: Drug: Sirolimus |
What is being measured
The primary outcome is the main question the study is designed to answer.
Remission of KHE and no use of sirolimus at one year follow-up.
The primary outcome is a binary variable. The primary outcome measure will be analyzed with binary logistic regression to estimate the odds ratio between the two groups.
Measured: From admission to follow-up one year
Secondary outcomes (7)
Remission of KHE and the dose of sirolimus at one year follow-up
At one year's follow-up, the participant may be on remission, but still taking sirolimus. The condition is a binary variable and the dose of sirolimus is a continuous variable.
Measured: From admission to follow-up one year
Relapse of KHE and the dose of sirolimus at one year follow-up
At one year's follow-up, the participant may suffer from relapse of KHE and still takes sirolimus. The period of time to the first relapse will be recorded as a time variable, and the cox regression survival analysis model will be used.The dose of sirolimus is a continuous variable. Whether this variable is normally distributed will be checked.
Measured: From admission to follow-up one year
Side effects of sirolimus
The outcome 4 will be described. Adverse events will be reported according to Common Terminology Criteria for Adverse Events, version 4.0 (CTCAE v4.0). Incidence of complications such as oral ulcers, abnormal liver enzymes, infections will be recorded. The blood concentration of sirolimus will be adjusted accordingly.
Measured: From admission to follow-up one year
Platelet count
Platelet count is one of the major indicators of response to treatment and will be used in a prognosis model to predict the clinical characteristics of patients with benefits. It is supposed to be greater than 100×10^9/L.
Measured: From admission to follow-up one year
Fibrinogen level
Fibrinogen level will be used in a prognosis model to predict the clinical characteristics of patients with benefits. It is supposed to be at 2-4g/L.
Measured: From admission to follow-up one year
Tumor volume
Tumor volume will be used in a prognosis model to predict the clinical characteristics of patients with benefits. The size of the tumor is supposed to shrink according to imaging evaluation. The tumor is supposed to be softer by palpation.
Measured: From admission to follow-up one year
Complaints
Complaints are subjective feelings. Whether there is pain, swelling, lameness or skin color change will be recorded as binary variables and used in a prognosis model to predict the clinical characteristics of patients with benefits.
Measured: From admission to follow-up one year

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Sirolimus in people with Kaposiform Hemangioendothelioma and Kasabach-Merritt Syndrome, run by Children's Hospital of Fudan University 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 6 inclusion and 5 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 26 Sep 2023. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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?
Remission of KHE and no use of sirolimus at one year follow-up. (time frame: From admission to follow-up one year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
