Safety and Efficacy of Hemoglobin F Inducers in Patients With Beta Thalassemia
Safety and Efficacy of Hemoglobin F Inducers in Patients With Beta Thalassemia: a Prospective 12 Months Study
The aim of this study is to determine the safety and therapeutic effect of HbF inducers (combination therapy: thalidomide and hydroxyurea) on beta thalassemia patients. The main objectives of this study are:
- To determine the therapeutic efficacy of HbF inducers (combination therapy: thalidomide and hydroxyurea) on hemoglobin level and blood transfusion in beta thalassemia patients.
- To determine the safety of HbF inducers (combination therapy: thalidomide and hydroxyurea) in beta thalassemia patients
- To determine effect of HbF inducers (combination therapy: thalidomide and hydroxyurea) on quality of life of beta thalassemia patients

Description détaillée
This is a two-arm comparative study. One group is the interventional group, in which all patients will receive thalidomide and hydroxyurea. Low-dose Thalidomide will be administered to patients at a low dose of 0.5 to 4 mg/kg orally every day for 12 months until continuous transfusion-dependency or unacceptable toxicity occurs. The starting dose of hydroxyurea will be 10-20 mg/kg per day. The second group will be the control group for blood transfusion.
In the intervention group, 114 confirmed diagnoses of beta thalassemia ascertained by Hemoglobin Electrophoresis or HPLC report performed pre-transfusion or genetic testing profile (comprising PCR or HBB gene sequencing) suggestive of β-thalassemia syndrome will be included. To assess the therapeutic efficacy of HbF inducers (combination therapy: thalidomide and hydroxyurea), the number of blood transfusions and hemoglobin level will be assessed as per the given schedule.
. Adverse events will be recorded at each follow-up to assess the safety of the therapy. The patient/guardian/parent will be specifically asked about paresthesia, rash, constipation, unexplained infections, bleeding symptoms, headache, syncope, focal weakness, and behavioral changes. All participants will be asked to report any adverse reactions and will be questioned about adverse events during the study visit. EORTC QLQ C-30 URDU version, a self-administered questionnaire, will be filled by each participant at baseline and 6 months.

Mesure des résultats |
Description de la mesure |
Délai |
|---|---|---|
|
Improvement in the hemoglobin level
Délai: 6 months
|
To evaluate the Improvement in Hemoglobin level, response criteria are defined as follows: Major response, an elevation in total Hb level of ≥2 g/dL Minor response, an elevation in total Hb level of 1 to 2 g/dL, or Hb not substantially increased (<1 g/dL) but the patients achieve Hb>7 g/L No response, an elevation in total Hb level of <1 g/dL |
6 months
|
|
Decrease in transfusion requirement
Délai: 6 months
|
To evaluate the decrease in transfusion requirement, response criteria are defined as follows: Major response: reduce transfusion requirements by ≥25% after 6 months of therapy compared to baseline. Minor response: reduce transfusion requirement by <25 % after 6 months of therapy, No response: same blood transfusion requirement as baseline |
