Beta-Thalassemia (B-THAL)

Beta-thalassemia (B-THAL) is an inherited blood disorder characterized by reduced levels of functional hemoglobin. With our company's profound expertise in B-THAL research, we are well-equipped to offer tailored solutions and comprehensive support to facilitate your research process from B-THAL therapy development to therapy commercialization.

Overview of B-THAL

B-THAL is an autosomal recessive blood disorder characterized by diminished levels of functional hemoglobin, a crucial protein that transports oxygen within red blood cells. This inherited condition poses a substantial global public health challenge, particularly in regions with high prevalence rates, including the Mediterranean, Middle East, and Southeast Asia. B-THAL is a rare condition, with a projected worldwide annual incidence of 1 in 100,000 individuals.

Pathogenesis of B-THAL

B-THAL arises from gene mutations that impact the production of beta-globin chains, a vital part of hemoglobin. These mutations can cause reduced or absent synthesis of beta-globin chains, disrupting the balance between alpha-globin and beta-globin chain production. Consequently, functional hemoglobin formation is impaired, leading to ineffective erythropoiesis and subsequent anemia.

Targets of B-THAL Therapy

Beta-Globin Gene Expression

Enhancing the production of β-globin chains or compensating for their defects are important targets for the development of B-THAL therapies. Hydroxyurea, butyrate derivatives, and histone deacetylase inhibitors are drug candidates currently under investigation for modulating β-globin gene expression.

Iron Metabolism and Chelation

Iron overload is a common complication in individuals receiving regularly transfused B-THAL. It is crucial to manage iron levels and prevent organ damage caused by excess iron deposits. Chelating agents, such as deferoxamine, deferiprone, and deferasirox, help prevent iron overload and its associated complications.

Types of B-THAL Therapy

Hematopoietic Stem Cell Transplantation (HSCT)

HSCT remains the sole therapeutic option for B-THAL. HSCT involves the transplantation of healthy stem cells from a compatible donor into the body of a HSCT individual, replacing the defective stem cells and restoring normal hematopoietic function.

Gene Therapy

Gene therapy is a new therapeutic method for B-THAL. Gene therapy utilizes lentiviral vectors containing human β-globin genes and ankyrin insulators to enhance gene transcription and translation, thereby augmenting the production of β-globin.
