Pompe disease is a rare genetic disorder, requiring lifetime treatment with IV enzyme replacement therapy (ERT). It is caused by a defect or mutation in the lysosomal enzyme acid α-glucosidase (GAA) resulting in severe heart and skeletal muscle myopathies.


We have identified a new class of small molecules with the ability to specifically and selectively bind to GAA in order to stabilize the enzyme in its optimal conformation and enhance its activity in lysosomes.


Pharmacological chaperone therapy (PCT) would combine the advantages of oral administration of small molecules, better distribution in tissues (including the central nervous system), and less cumbersome treatment associated with lower cost compared to ERT.

State of progress

GAA specific and selective chaperone activity has been demonstrated in vitro and ex vivo on patient fibroblasts, the next step is the validation of POC in vivo on mice.


Oral treatment of Pompe disease would save lives in cases where ERT is ineffective. In addition, in combination with ERT, it would allow for the reduction of high doses of the enzyme administered and the spacing of perfusions to reduce side effects and improve patients' quality of life.
