Parkinson’s Disease – Unmet Need – Detailed, Expanded Analysis: Psychosis In PD (US/FR/DEU/UK)

Parkinson’s disease (PD) is widely recognized as a motor disorder, but PD is also associated with a diverse set of nonmotor symptoms. Surveyed neurologists estimate that 20% of their PD patients experience psychosis, and DRG Epidemiology data suggest the percentage could be even higher. Few antipsychotic agents have been rigorously tested in the PD population, but prescribing of these agents is common; left untreated, psychosis can have a devastating effect on PD patients’ quality of life. One antipsychotic agent is approved for PD psychosis in the United States (Nuplazid) and one in Europe (clozapine), but clear unmet need remains. Understanding prescriber perceptions of the available on- and off-label options and the drivers of clinical decision-making in PD psychosis will help developers of antipsychotics and other agents gauge the market opportunity in PD and identify levers for new product positioning and differentiation in this underserved therapy market.

QUESTIONS ANSWERED

  • What drug attributes are most influential in prescribing for psychosis in the PD population? How do Nuplazid, clozapine, and commonly prescribed off-label agents perform on these attributes?
  • What are the specific areas of unmet need and opportunity in the treatment of PD psychosis?
  • Based on conjoint analysis and TPP simulation, what trade-offs between efficacy, safety, and price are neurologists willing to make for a hypothetical new antipsychotic agent for PD psychosis?

PRODUCT DESCRIPTION

Unmet Need provides quantitative insight into U.S. and European physician perceptions of key treatment drivers and goals and the current level of unmet need for a specific disease. Commercial opportunities are analyzed, and the extent to which emerging therapies may capitalize on these opportunities is evaluated.

Markets covered: United States, United Kingdom, France, Germany

Primary research: Survey of 60 U.S. and 30 European neurologists, fielded in February 2020

Key drugs: Nuplazid (pimavanserin), clozapine, quetiapine, aripiprazole, olanzapine, risperidone, ziprasidone
