- Detailed Description
Study titled Long Term Beta Thalassemia Treatment: Findings From The Extension Period Of Phase 2 Clinical Trial, conducted at the National Institute of Blood Disease \& Bone Marrow Transplantation (NIBD \& BMT).
This study focuses on the long-term comparison of combination therapy (thalidomide and hydroxyurea) versus thalidomide alone in treating beta thalassemia. The objective is to evaluate the efficacy and safety of the combination therapy compared to thalidomide alone, with the hypothesis that the combination will be more effective. Beta thalassemia is defined as an autosomal recessive disorder affecting beta-globin production, influenced by genetic modifiers. Key variables include hemoglobin, red blood cells, leukocyte count, reticulocyte count, platelets, lactate dehydrogenase, nucleated red blood cells, ferritin, bilirubin, Serum Glutamate Pyruvate Transaminase, creatinine, transfusion frequency, spleen and liver size, hemoglobin subunit beta \[ Homo sapiens (human) \] mutation, and certain polymorphism in gamma globin gene . The study took place at NIBD hospital over three years, designed as a Phase 2 single-center, two-arm open-label interventional study with a sample size of 30 participants using simple randomized sampling. Inclusion criteria are beta thalassemia major/intermediate patients aged 8-35 years, while exclusion criteria include patients with liver dysfunction, married patients, lactating mothers, and those with a history of thrombosis and fits. Data will be collected through clinical interviews and medical record reviews and analyzed using (Statistical Package for the Social Sciences.

Group Intervention Description combination therapy (thalidomide and hydroxyurea) thalidomide and hydroxyurea In this group, participants were treated with combination therapy that includes thalidomide and hydroxyurea at the dose of 100mg/day at night with aspirin and 500mg /day respectively. thalidomide alone Thalidomide In this group, participants were treated with thalidomide at the dose of 100mg/day at night with aspirin.
- Primary Outcome Measures
Name Time Method leukocyte count 3 years Measure the effect on in leukocyte count Leukocyte count will be assessed using a complete blood count (CBC) test, measured in thousands of cells per microliter (thousand cells/µL) of blood. This test involves analyzing a venous blood sample with an automated hematology analyzer to determine the total number of white blood cells present.
Transfusion Frequency: 3 years Document and compare the frequency of blood transfusions required by patients in both treatment arms over the study period.
Transfusion frequency will be assessed by recording the number of blood transfusions a patient receives over a specified period, such as weekly, monthly, or annually. This data will be collected from patient medical records and/or transfusion logs, ensuring accurate tracking of each transfusion event.hemoglobin levels 3 years Measure the improvement in hemoglobin levels Hemoglobin levels will be assessed using a complete blood count (CBC) test, measured in grams per deciliter (g/dL) of blood. This test is conducted through a venous blood sample, which is then analyzed using an automated hematology analyzer to determine the hemoglobin concentration.
red blood cell count. 3 years Measure the improvement in red blood cell count. Red blood cell count will be assessed using a complete blood count (CBC) test, measured in millions of cells per microliter (million cells/µL) of blood. This test is conducted through a venous blood sample, analyzed using an automated hematology analyzer to determine the number of red blood cells present.
reticulocyte count 3 years Measure the effect on reticulocyte count Reticulocyte count will be assessed using a complete blood count (CBC) test, measured as a percentage of the total red blood cells or as an absolute number per microliter (µL) of blood. This test involves analyzing a venous blood sample with an automated hematology analyzer, which identifies and quantifies reticulocytes using specific staining techniques.
- Secondary Outcome Measures
Name Time Method Spleen and Liver Size 3 years Measure changes in spleen and liver size as a response to the treatments. Spleen and liver size will be assessed using imaging techniques such as ultrasound.. Measurements will be reported in centimeters (cm), capturing the dimensions of each organ to evaluate any enlargement or abnormalities.
Serum Ferritin Levels 3 years Evaluate the effectiveness of the combination therapy in reducing serum ferritin levels, indicating decreased iron overload.
Serum ferritin levels will be assessed using a blood test, measured in nanograms per milliliter (ng/mL). A venous blood sample will be analyzed in a clinical laboratory using immunoassay techniques to determine the concentration of ferritin, providing an indicator of the body's iron stores.bilirubin 3 years Monitor and compare changes in biochemical parameters such as bilirubin. Bilirubin levels will be assessed through a blood test, typically measured in milligrams per deciliter (mg/dL). This test analyzes a venous blood sample to determine the concentration of bilirubin, a pigment produced from the breakdown of red blood cells, providing insights into liver function and potential health conditions such as jaundice or liver disease.
lactate dehydrogenase. 3 years Monitor and compare changes in biochemical parameters such as lactate dehydrogenase.
Lactate dehydrogenase (LDH) levels will be assessed through a blood test, measured in units per liter (U/L). This test analyzes a venous blood sample to determine the concentration of LDH, an enzyme involved in cellular metabolism. Elevated LDH levels may indicate tissue damage or disease.Serum Glutamate Pyruvate Transaminase, 3 years Monitor and compare changes in biochemical parameters such as Serum Glutamate Pyruvate Transaminase. Serum Glutamate Pyruvate Transaminase, also known as alanine aminotransferase (ALT), will be assessed through a blood test, measured in units per liter (U/L). This test analyzes a venous blood sample to determine the concentration of ALT, an enzyme primarily found in the liver cells. Elevated ALT levels may indicate liver damage or disease.
creatinine 3 years Monitor and compare changes in biochemical parameters such as creatinine. Creatinine levels will be assessed through a blood test, typically measured in milligrams per deciliter (mg/dL) or micromoles per liter (µmol/L). This test involves analyzing a venous blood sample to determine the concentration of creatinine, a waste product from muscle metabolism filtered by the kidneys. Monitoring creatinine levels helps evaluate kidney function and detect conditions such as kidney disease or impaired renal function.
Genetic Modifiers: 3 years Analyze the influence of genetic modifiers. Genetic modifiers will be assessed through genetic testing,e.g thalassemia genetic profile focusing on specific genes or genetic variations known to influence the expression or function of proteins related to the condition under study. This analysis helps identify how genetic factors may modify disease progression, treatment response, or other relevant outcomes.
