Alpha Thalassemia: Understanding

Alpha Thalassemia: Overview

Alpha thalassemia is a genetic blood disorder caused by mutations in the HBA1 and HBA2 genes, located on chromosome 16, which are responsible for producing the alpha-globin chains of hemoglobin. This leads to a deficiency or absence of alpha-globin, disrupting the synthesis of hemoglobin and resulting in ineffective erythropoiesis (red blood cell production) and increased red blood cell destruction (hemolysis). The severity of the disorder depends on the number of affected alleles, with forms ranging from mild anemia in alpha thalassemia minor to more severe conditions such as hemoglobin H disease and hydrops fetalis, the latter being life-threatening. Symptoms include anemia, fatigue, pallor, splenomegaly, and, in severe cases, organ damage. Alpha thalassemia is most prevalent in regions where malaria is endemic, such as Southeast Asia, the Middle East, and Sub-Saharan Africa, where it provides a survival advantage against malaria, explaining its evolutionary persistence in these areas.

Hemoglobin H forms when only one normal alpha-globin gene is inherited, leading to significantly impaired alpha-globin production. In the neonatal period, this results in an excess of gamma-globin chains, while in adults, there is an excess of beta-globin chains. Since free alpha-globin chains are insoluble, they precipitate in the red blood cells, causing damage. On the other hand, both gamma and beta-globin chains are soluble and can form homotetramers. Hemoglobin H is composed of four beta chains, while HbBarts consists of four gamma chains. These hemoglobins, although able to form, are unstable, and some of the molecules precipitate inside the cells, leading to a variety of clinical manifestations.

Hemoglobin H can lead to chronic hypochromic microcytic anemia and hemolytic anemia, with symptoms often exacerbated during periods of oxidant stress. This can be understood as a combination of ineffective erythropoiesis and increased hemolysis. The microcytic hypochromic anemia results from impaired hemoglobin production due to reduced alpha-chain synthesis, coupled with hyperhydration of the red blood cells. The cause of this hyperhydration is not entirely clear, but one theory suggests that the K-Cl cotransporter stops early, preventing the normal loss of potassium-chloride and water that typically occurs during red blood cell remodeling. Additionally, Hemoglobin H has a significantly shortened red blood cell lifespan, ranging from 12 to 19 days, compared to the normal 28 to 37 days. This reduced survival is attributed to two main factors: an abnormal red blood cell membrane that increases rigidity and the presence of inclusion bodies. These inclusion bodies are believed to be aggregates of beta-chain tetramers, which precipitate within the red blood cells, causing damage.

Alpha thalassemia traits are believed to offer a protective advantage against malaria, and in regions with high malaria prevalence, the trait can be found in up to 90% of the population. Similarly, Hemoglobin H is most commonly found in populations residing in warm climates, particularly in regions with high malaria incidence. The highest rates of Hemoglobin H are observed in Southeast Asia, the Mediterranean, and the Middle East. Hemoglobin Constant Spring, the most common form of non-deletion alpha thalassemia, is prevalent in certain areas as well. It affects approximately 1% to 2% of individuals in northeastern Thailand, 5% to 8% of individuals in southern China, and about one-quarter of women in some ethnic minority groups in Vietnam.

Supplementation with folic acid is recommended for individuals with Hemoglobin H, as it helps to support red blood cell production in the presence of hemolytic anemia. Patients with Hemoglobin H are at risk of clinical manifestations due to oxidative damage, which can worsen during periods of stress, such as infection or the use of oxidant drugs. Regular blood counts should be monitored to assess the severity of anemia, and transfusion may be necessary during times of increased oxidative stress. Chronic transfusion therapy requires close monitoring for complications, such as iron overload, and patients should receive iron chelation therapy as needed, particularly in the second and third decades of life.

It also helps to understand clinical trial details, expressive pharmacological action, agreements and collaborations, and the latest news and press releases.

Alpha Thalassemia Emerging Drugs

Mitapivat: Agios Pharmaceuticals, Inc.

Mitapivat (AG-348) is a first-in-class oral, small-molecule, allosteric activator of the red blood cell (RBC)-specific form of pyruvate kinase (PK-R), which has shown efficacy and safety and has received US approval for the treatment of anemia in adults with PK deficiency. In thalassemia mouse models, it reduced markers of ineffective erythropoiesis and improved anemia. Currently, the drug is in Preregistration stage of its clinical trial for the treatment of Alpha Thalassemia.

Luspatercept: Bristol-Myers Squibb

Luspatercept is a recombinant fusion protein that acts as an erythroid maturation agent, showing significant potential in the treatment of alpha thalassemia, particularly in patients with hemoglobin H disease. Its mechanism of action involves binding to specific ligands of the transforming growth factor-beta superfamily, thereby inhibiting the downstream Smad2/3 signaling pathway, which is often overactivated in conditions characterized by ineffective erythropoiesis. By blocking this signaling pathway, luspatercept promotes late-stage erythroid differentiation and maturation, enhancing the production of functional red blood cells. Currently, the drug is in Phase II stage of its clinical trial for the treatment of Alpha Thalassemia.
