Chiesi Global Rare Diseases Announces Publication of Results from Phase 3 BALANCE Study in Fabry Disease

Date: 23/01/2024

Chiesi Global Rare Diseases, a business unit of the Chiesi Group established to deliver innovative therapies and solutions for people affected by rare diseases, today announced the publication of data from the Phase 3 BALANCE study that evaluated efficacy, safety and tolerability of pegunigalsidase alfa versus agalsidase beta in adult patients with previous agalsidase beta treatment and deteriorating renal function. The results are published in the peer-reviewed Journal of Medical Genetics (“Head-to-head trial of pegunigalsidase alfa versus agalsidase beta in patients with Fabry disease and deteriorating renal function: results from the 2-year randomised phase III BALANCE study” Wallace EL, et al. J Med Genet 2023; doi: 10.1136/jmg-2023-109445)


Pegunigalsidase alfa, a PEGylated enzyme replacement therapy (ERT), is a recombinant human α-Galactosidase A enzyme expressed in plant-cell culture. It is now approved for the treatment of adults with Fabry disease in the United States, European Union, and Great Britain.


“There continues to be a general lack of awareness and a limited appreciation of the numerous unique challenges that people living with Fabry disease face,” said Giacomo Chiesi, head of Chiesi Global Rare Diseases. “This is the first randomized, double-blind, head-to-head clinical trial of ERTs in Fabry disease, and it would not have been possible without the incredible support from investigators, patients, and families who dedicated two years of their lives to advance this important research. We are pleased to provide patients with Fabry disease an additional treatment option and will continue our work to support millions of people affected by rare diseases around the world.”


The BALANCE study included 77 adults with Fabry disease with an annualized eGFR slope more negative than −2mL/min/1.73m2/year who had received agalsidase beta for at least one year (on average almost six years). Participants were randomized 2:1 to receive 1mg/kg of pegunigalsidase alfa or agalsidase beta every two weeks for two years.
