The document discusses patient support programs for rare and orphan drugs. It notes that orphan drugs have unique challenges including small patient populations, difficulty in diagnosis, and reimbursement challenges. Patient support programs aim to help patients access therapy and navigate reimbursement and clinical support. They provide services like financial assistance, nursing care, pharmacy services, and adherence programs. The goal of these programs is to allow patients access to treatment, assist them in coordinating care, and generate real-world data on drug effectiveness outside of clinical trials to help demonstrate value to payers and accelerate patient access.
