FDA approved

XURIDEN® (uridine triacetate, Wellstat Therapeutics Corporation, Gaithersburg, MD)

Rare disease treatment for hereditary orotic aciduria , a rare metabolic disorder, reported in approximately 20 patients worldwide. Patients cannot synthesize adequate amounts of uridine and consequently can suffer from hematologic abnormalities, failure to thrive, a range of developmental delays, and episodes of crystalluria leading to obstructive uropathy

Reg Pathway : Orphan designation, priority review, granted rare pediatric disease priority review voucher

Indication : treatment of hereditary orotic aciduria

Efficacy :

Open-label study in 4 patients (3 to 19 years), 6 weeks.

  • Primary endpoint was stability of hematological paramters (eg neutrophil count, percent neutrophils, white blood cell count, mean corpuscular volume)
  • Patients 1 and 3 met pre-specified criteria
  • Patient 2 pre-specified criteria remained stable
  • Patient 4 did not meet the pre-specified endpoint
  • In 6-mo extension treatment, hematologic parameters for patients normalized or remained stable
  • Growth improved or remained stable

Safety : No adverse reactions

SUMMARY  Congratulations to Wellstat Therapeutics for pursuing and succeeding in drug development in an ultra rare potentially life-threatening, genetic disorder
