About PGM1 Deficiency

Currently there is no approved product for the treatment of PGM1-CDG.

PGM1 Deficiency is caused by loss of function mutations in the PGM1 gene encoding an enzyme responsible for the interconversion of glucose-6-phosphate to glucose-1-phosphate. Glucose-1-phosphate can be utilized to supply UDP-galactose, a substrate that donates galactose subunits for glycoprotein synthesis.

We believe that substrate replacement with CERC-801 in patients with PGM1 Deficiency should increase available UDP-galactose pools and repair galactose-deficient glycoproteins.

Mechanism of Action

CERC-801 is an ultra-pure formulation of D-galactose that serves as a substrate replacement therapy. Oral administration of D-galactose replenishes critical metabolic intermediates, reduced or absent due to a genetic mutation, to support glycoprotein synthesis, maintenance and function.
