'I am excited to have the opportunity to offer ELX-02 to my cystinosis patients, a new potential treatment option which has exhibited positive results in cellular and animal models with dose-dependent reductions in white blood cell cystine levels, a biomarker used to monitor cysteamine therapy and to predict clinical benefit,' said Dr.
Nephropathic cystinosis is a rare, life-threatening metabolic lysosomal storage disorder that causes toxic accumulation of cystine in all cells, tissues, and organs in the body.

Cystine stones caused by a hereditary disorder that results in excess cystine in urine
As a rare autosomal-recessive metabolic disorder, cystinosis is caused by defective transport of cystine across the lysosomal membrane.[1] Once the diagnosis of cystinosis is confirmed, specific treatment with cysteamine, an aminothiol, should be applied to the patient as soon as possible in order to preserve renal function and improve growth in affected children.[2] Cysteamine is the only specific drug approved by the Food and Drug Administration for cystinosis.
