Marketed therapies are often sufficient in early stages of Parkinson’s disease (PD), but as the disease progresses, they impose a considerable pill burden, progressively lose efficacy, and are not sufficient to control the virtually inevitable emergence of motor response complications in advanced stages of the disease. Opportunity in this arena has spurred the development of a range of new therapies targeting motor symptoms in PD. With the recent launches of Rytary, Xadago, and Gocovri, and with half a dozen others in late-phase development, understanding how prescribers perceive and plan to incorporate new brands is crucial for developers facing a complicated, highly genericized, and increasingly competitive market.

Questions Answered

  • How do neurologists currently prescribe or plan to prescribe recently launched brands (i.e., Rytary, Xadago, and Gocovri)?
  • How do surveyed neurologists plan on incorporating late-phase therapies into the treatment algorithm?
  • What are the top reasons why some neurologists do not prescribe or would refrain from prescribing recently launched or emerging brands?
  • How will the availability of new PD brands impact current prescribing in PD? How will generic Rytary impact the use of current and emerging PD therapies?
