Testing SIROLIMUS in Beta-thalassemia Transfusion Dependent Patients
Italy26 participantsStarted 2019-06-27
Plain-language summary
Beta-thalassemias are hereditary blood disorders caused by reduced or absent synthesis of hemoglobin beta chains, with variable outcomes ranging from severe anemia to clinically asymptomatic individuals. Treatment is symptomatic and thalassemia is a major unmet medical need. Survival is increased, even in patients needing transfusions, in comparison with a few years ago, but the quality of life is poor for many patients. In some patients, an anomalous expression of gamma-globin genes has been observed, with a consequent rise in Fetal Hemoglobin levels. The patients displaying a clinical phenotype known as Hereditary Persistence of Fetal Hemoglobin (HPFH) exhibit a positive clinical status. To mimick HPFH, several compounds able to induce expression of fetal hemoglobins (HbF) have been evaluated. Within this framework, sirolimus is particularly interesting as an inducer of HbF. It has been used for many years for different indications and the available preclinical evidence warrant the start of a clinical development plan in thalassemia. The investigators propose a clinical trial in beta-thalassemia patients, designed to evaluate the effect of sirolimus on several parameters related to red blood cell status and to the level of HbF in particular, as a first step for the full clinical development in this new indication.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
* Patients over 18 years of age;
* Patient able to understand the informed consent and to sign it before any study procedure;
* With β+/β+ and β+/β0 thalassemia genotype;
* Documented diagnosis of major or intermediate thalassemia transfusion-dependent (nr of transfusion not less than 8 over the past 12 months before selection);
* On regular transfusion since at least 6 years;
* With splenectomy performed at least 60 days before selection or spleen dimensions \< 20 cm in the largest part as detected by abdominal echography;
* Female participants who are surgically sterilised / hysterectomised or post-menopausal for longer than 2 years or female participants of childbearing potential using and/or willing to continue using a medically reliable method of contraception for the entire study duration, such as oral, injectable, or implantable contraceptives, or intrauterine contraceptive devices, or using any other method considered sufficiently reliable by the investigator in individual cases. Patients must be counseled concerning measures to be used to prevent pregnancy and potential toxicities prior to the first dose of sirolimus;
* Patient willing to follow all the study requirements and perform all the study visits and to cooperate with the investigator;
* Patient followed by the same clinical site since at least 6 months.
Note that patients will be treated with oral sirolimus only in the case their Erythroid Precursor Cells (ErPCs) are responsive to the in vitro treatment wit…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
