Alpha-Thalassemia (A-THAL)

Alpha-thalassemia is a form of thalassemia. With our company's profound expertise in A-THAL research, we are well-equipped to offer tailored solutions and comprehensive support to facilitate your research process from A-THAL therapy development to therapy commercialization.

Introduction to A-THAL

A-THAL is a rare genetic disorder characterized by reduced or absent production of alpha-globin chains, resulting in abnormal hemoglobin formation. There is a dearth of public health data regarding A-THAL in the United States. However, in California, the prevalence of A-THAL is observed to be 1 in 10,000 births. There are two main forms of A-THAL associated with serious health problems: hemoglobin (Hb) Bart's hydrops fetalis and hemoglobin H (HbH) disease.

Disease Types Phenotype Onset Time
Hemoglobin (Hb) Bart's Hydrops Fetalis Mild or Moderate Anemia Onset in Childhood or Adulthood
Hemoglobin H (HbH) Disease Severe Anemia Onset during the Fetal Period

Pathogenesis of A-THAL

The pathogenesis of A-THAL is associated with impaired alpha-globin chain production, leading to imbalanced globin chain synthesis and abnormal hemoglobin formation. This affects the normal structure and function of red blood cells, leading to their premature destruction and subsequent anemia. Potential genetic mutations that cause A-THAL involve deletions or point mutations in the HBA1 and HBA2 genes. These mutations result in reduced or absent α-globin chain synthesis.

Targets of A-THAL Therapy

Transthyretin Amyloid Cardiomyopathy (ATTR-CM)


Enhancing the synthesis of α-globin chains and promoting the formation of functional hemoglobin are important targets for the development of A-THAL therapies. For example, luspatercept may increase hemoglobin levels and reduce the need for transfusions in individuals affected by A-THAL.

Pyruvate Kinase-R (PKR)

Pyruvate kinase-R (PKR) is an enzyme that plays a key role in erythrocyte glycolysis. The drug under investigation, AG-348, can enhance the activity of pyruvate kinase-R (PKR), increase red blood cell energy production, and improve erythropoiesis.

A-THAL Gene Therapy

Using lentiviruses or adeno-associated viruses (AAV), functional copies of the HBA1 and HBA2 genes encoding alpha-globin chains are delivered into the hematopoietic stem cells of A-THAL individuals. Once integrated into the genome, these genes can drive the production of normal alpha globin chains, thereby restoring functional hemoglobin.

Our Services

Drawing upon our deep expertise in biotechnology and extensive experience in the industry, our company offers all-encompassing solutions for diagnostic and therapeutic research dedicated to A-THAL.

Genetically Engineered Models
Genetically engineered models are created by modifying the genetic makeup of experimental animals to simulate specific characteristics or mutations associated with human A-THAL. At our company, scientists specialize in using CRISPR/Cas9 and transgenic technologies to create knockout, knock-in, and transgenic models.
Optional Models
  • α-globin Gene Knockout (α-KO) Models
  • A-THAL Transgenic Models
  • A-THAL Knock-in Model
Optional Species Mice, Zebrafish, Non-human Primates (Rhesus Macaques), Others
