Two studies conducted by PHAR were presented as posters at AMCP 2022. The first study, in partnership with Sunovion Pharmaceuticals, developed clinical consensus on the use of on-demand treatments for Parkinson’s disease (PD) by convening experts to participate in a RAND/UCLA modified Delphi panel. In most evaluated scenarios, panelists agreed on-demand treatment is appropriate for PD patients with OFF episodes, especially for patients experiencing a significant functional impact. The second study, in collaboration with Genentech, presented the interim results of their claims-based algorithm used to identify patients with neuromyelitis optica spectrum disorder (NMOSD). The algorithm helps distinguish patients with NMOSD from patients with multiple sclerosis and other central nervous system inflammatory disorders, allowing researchers and clinicians to better estimate NMOSD burden. The posters can be viewed on the PHAR publications page and abstracts printed in the March supplement issue of the Journal of Managed Care + Specialty Pharmacy.
