Leadiant Announces Cystaran Availability Through Walgreens Speciality Pharmacy (U.S.)

Leadiant Biosciences, Inc. is pleased to share with the cystinosis community that Cystaran® (cysteamine ophthalmic solution) 0.44% will be available for order early next week. We have heard your frustrations, and we apologize for the interruption in product availability you may have had. Getting Cystaran back to you has been our top priority. The product shortage was the result of unexpected delays with manufacturing.

On Monday, August 14, Walgreens Specialty Pharmacy will be contacting patients to schedule shipping and delivery of Cystaran. If you received 2 bottles, you will receive the balance of your bottles to make your monthly order whole. If you were placed on the back-order list and received 0 bottles, you will be shipped your full monthly supply.

We greatly appreciate the Cystinosis community’s patience and understanding while these manufacturing challenges were resolved.

For additional questions or to order Cystaran, please contact Walgreens Specialty Pharmacy at 1-877-534-9627.

Walgreens Specialty Pharmacy Limit Fulfillment

On behalf of Leadiant Biosciences, Inc., I’m writing to inform you that we are experiencing a product shortage of Cystaran® (cysteamine ophthalmic solution) 0.44%, of which we hope will be a short-term impact on the patient community. Effective Monday, July 17, Walgreens Specialty Pharmacy will limit fulfillment of all new and refill prescriptions for Cystaran eye drops, to a maximum of two bottles per patient. The goal is to maximize the number of patients who continue to have access to Cystaran while product at Walgreens is limited. This action is necessary to accommodate a product supply interruption that the manufacturer of Cystaran is currently experiencing. We anticipate strong interest in learning more about this issue and concern among the patient and caregiver community. Leadiant understands the cystinosis community relies on Cystaran eye drops and we are committed to working diligently with the manufacturer of Cystaran to determine a solution as soon as possible. We will continue to provide you with updates as new information becomes available.

Best regards,

Lesli King
