About This Medication

# Sentynl Cares | NULIBRY Access and Support Patient Guide: How to Get Nulibry (fosdenopterin) at Low or No Cost Nulibry (fosdenopterin) is an FDA-approved intravenous medication designed to **reduce the risk of mortality** in children with **molybdenum cofactor deficiency (MoCD) Type A**, a rare, life-threatening genetic disorder.[4][6][7] This patient-friendly guide explains the **Sentynl Cares | NULIBRY Access and Support** program from Sentynl Therapeutics, Inc., focusing on its **Copay Assistance Program** to help eligible families manage costs.[1][2] ## About Nulibry (fosdenopterin) **Nulibry** is a **substrate replacement therapy** that provides cyclic pyranopterin monophosphate (cPMP), which the body converts to molybdopterin and then molybdenum cofactor. This cofactor activates enzymes like sulfite oxidase, reducing harmful sulfite buildup that damages the brain in MoCD Type A.[4][10] MoCD Type A is an ultra-rare, autosomal recessive condition where babies often show severe neurological issues soon after birth, with most untreated children not surviving past age 3-4 years.[6][10] Clinical data showed Nulibry improved survival compared to untreated, genetically matched historical controls.[4][7][10] It's given daily via IV infusion, potentially at home if approved by a provider.[8] **Key warnings**: Nulibry can cause **photosensitivity**—avoid direct sunlight and use sunscreen/UV-protective clothing.[4][7] It's for confirmed MoCD Type A via genetic testing (pathogenic variants in the MOCS1 gene).[6] ## Who Qualifies for Sentynl Cares | NULIBRY Access and Support?
