Trial Summary

Will I have to stop taking my current medications?

The trial protocol does not specify if you must stop taking your current medications. However, certain medications like hydroxyurea, erythropoiesis-stimulating agents, and some herbs or supplements must be stopped 12 to 24 weeks before joining, depending on your transfusion status.

What makes the drug Luspatercept unique for treating Thalassemia?

Luspatercept is unique because it works by enhancing red blood cell production, which is different from traditional treatments that often focus on managing symptoms or complications of Thalassemia. This mechanism offers a novel approach to improving anemia in patients with this condition.12345

What is the purpose of this trial?

This trial is testing a drug called luspatercept in children with β-thalassemia to see if it is safe and how it works in their bodies. The study includes children who need regular blood transfusions and those who do not. Luspatercept helps the body make more red blood cells, which can lessen the need for transfusions. Luspatercept is a newly approved treatment for reducing the need for blood transfusions in adults.

Interventions

  • Luspatercept
Trial Overview The study tests the safety and how the body processes luspatercept (ACE-536) in young patients requiring regular red blood cell transfusions due to β-thalassemia. It has two parts: one for ages 12-<18 and another for ages 6-<12, each with dose escalation followed by expansion cohorts.

Findings from Research

Enzyme replacement therapy with sebelipase alfa significantly improved survival rates in infants with lysosomal acid lipase deficiency (LAL-D), with 79% surviving to 12 months and 68% to 5 years, while also promoting normal growth and development.
The treatment was well tolerated, with no patients discontinuing due to adverse events, and most infusion-related reactions were mild to moderate, indicating a favorable safety profile.
Long-term survival with sebelipase alfa enzyme replacement therapy in infants with rapidly progressive lysosomal acid lipase deficiency: final results from 2 open-label studies.Vijay, S., Brassier, A., Ghosh, A., et al.[2023]
A patient with mucopolysaccharidosis type VI experienced significant infusion-associated reactions after starting enzyme replacement therapy with galsulfase, which made it difficult to tolerate the recommended infusion rate.
By reducing the infusion rate and adding steroids to the premedication regimen, the patient was able to continue treatment successfully without further infusion-related reactions, demonstrating a safe and effective adjustment strategy for administering galsulfase.

Sebelipase alfa (Kanuma™) is an enzyme replacement therapy approved for treating lysosomal acid lipase (LAL) deficiency, which helps reduce lipid accumulation and improve related health issues like dyslipidaemia and liver abnormalities.
Administered via intravenous infusion once weekly or biweekly, sebelipase alfa received its first approval in the EU in August 2015, with additional regulatory submissions in the USA, Mexico, and Japan, indicating its global recognition as a treatment option.
