Dear Cystinosis Community,

Leadiant Biosciences, Inc. recognizes the challenges as a result of the pandemic due to COVID-19. Our team is sensitive to concerns regarding the availability of critical medications. We are monitoring the pandemic and our supply of Cystaran for the treatment of patients with cystinosis with corneal crystals. Our supply chain is secure at this time and we do not anticipate any shortage including considerations of transport of the medication from the specialty pharmacy to you. Leadiant will update the status of Cystaran supply on our product website as well as providing this information and link to the Cystinosis Research Foundation (CRF) and Cystinosis Research Network (CRN). Please feel free to visit our site at and contact us with any questions or concerns.

Thank you,
The Leadiant Team
