Active clinical trials for "Thalassemia"

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.

This is a Phase 2 open-label, single-arm design study with dose escalation by subject cohort . The study is designed to monitor the PTG-300 safety profile, to obtain preliminary evidence of efficacy of PTG-300 for the treatment in β-thalassemia.

Thalidomide is known to have hypnosedative, immuno-modulatory and anti-angiogenic effects. The drug is widely used in several neoplastic disorders (e.g. multiple myeloma and malignant melanoma), inflammatory conditions (e.g. Crohn's disease) and skin disorders (e.g. leprosy). Thalidomide has been successfully used in adult thalassemia patients. The current study explores its role in transfusion-dependent thalassemia patients.

The effect of N-acetylcysteine as antioxidant and its effect on pretransfusion hemoglobin and iron overload in patients with thalassemia were compared to patients who didn't receive n-acetylcysteine after 3 months of study duration

The study aims to evaluate the effect of local non surgical periodontal therapy on the systemic pro-inflammatory markers in the β-thalassemia (TM-β) patients with chronic periodontitis and systemically healthy demographically matched controls with chronic periodontitis. Both groups will receive non surgical periodontal therapy.

This proof-of-mechanism study is being performed to investigate the safety, tolerability, efficacy, pharmacokinetics, and pharmacodynamics of multiple oral doses of bitopertin in adults with NTD beta-thalassemia. This study consists of two parts: Part 1 - The main study - 16 weeks in total: Participants will undergo a 6-week dose-escalation period followed by 10 weeks of treatment at the attained target dose. Part 2 - Open Label Extension (OLE) - up to an additional 12 months. Participants will be given the option to enroll into the OLE once the 16-week treatment of Part 1 has been completed. Participants who decide not to enroll in the OLE, at the end of Part 1 will enter a 6-week follow-up period.

Objectives Primary objective: • To determine the efficacy and safety of the combination therapy of Hydroxyurea and thalidomide in beta-thalassemia patients. Secondary objective: • To determine the change in liver and spleen size of beta-thalassemia patients on the combination therapy A single-arm non-randomized trial to evaluate the efficacy and safety of combination therapy of hydroxyurea and thalidomide in beta-thalassemia patients. It was a twelve months study. Participants were monitored for six months on Hydroxyurea alone and then the combination therapy of hydroxyurea and thalidomide for another six months. Findings of physical examination, vital signs, laboratory, and ultrasound findings were recorded at baseline, during and end of the study. Sample Size and Population This study included 135 Beta-thalassemia patients.

The thalassemias are a group of inherited hematologic disorders caused by defects in the synthesis of one or more of the hemoglobin chains [1]. Thalassemia are classified into the alpha (α) and (β) thalassemia, which contain deficits in (α) and (β) globin production respectively (α)thalassemia are caused by decreased production of alpha-globin chains from chromosome 16. There are 4 types of (α) thalassemia: thalassemia silent carrier thalassemia carrier . Hemoglobin H disease thalassemia major Beta-thalassemia are caused by point mutations or more rarely deletions in the β-globin gene on chromosome 11, leading to reduced (β+) or absent (β0) synthesis of the β chains of hemoglobin. Imbalances of globin chains cause hemolysis and impair erythropoiesis [4-7]. β-thalassemia can be classified into: Beta Thalassemia major, Beta Thalassemia intermedia, Beta Thalassemia minor Thalassemia is a chronic disease that presents a range of serious clinical and psychological challenges. The effects of thalassemia on physical health can lead to physical deformity, growth retardation, and delayed puberty [9, 10]. Its impact on physical appearance, e.g., bone deformities and short stature, also contributes to a poor self-image [10, 11]. Severe complications such as heart failure, cardiac arrhythmia, liver disease, endocrine complications, and infections are common among thalassemia patients [8, 12].

To study the expression pattern of PUM1 gene in patients with sickle cell anemia and β-thalassemia intermedia. To detect PUM1 protein levels in sickle cell anemia and β-thalassemia intermedia patients. To correlate PUM1 gene expression pattern and protein levels with HbF levels in sickle cell anemia and β-thalassemia intermedia patients.
