What Is PERSERIS KIT?

Product Profile

Attribute	Description
Active Ingredient	Risperidone (microspheres)
Formulation	Long-acting injectable (LAI) in an autoinjector
Indication	Schizophrenia in adults
Approval Date	November 2019 (FDA)
Manufacturer	Indivior plc (original approval), Johnson & Johnson (distribution rights)

Unique Selling Proposition

• Once-monthly dosing
• Autoinjector for ease of administration
• Improved adherence compared to oral therapy

What Are the Market Dynamics Influencing PERSERIS KIT?

1. Global Mental Health Burden and Schizophrenia Prevalence

Schizophrenia affects approximately 20 million people worldwide [1], with a significant treatment gap. US estimates report nearly 1% prevalence in adults [2]. Rising awareness and diagnosis rates directly influence LAI adoption.

2. Evolving Treatment Paradigms and Patient Adherence

Non-adherence rates in schizophrenia are estimated between 50-60% [3], leading to relapses and hospitalization. LAIs such as PERSERIS address this by ensuring consistent medication delivery, improving outcomes and reducing total healthcare costs.

3. Competitive Landscape

Competitors	Key Products	Market Share (Estimated)	Differentiators
Janssen	Risperdal CONSTA	~70% [4]	Depot formulation, well-established
Novartis	Aristada	~20% [4]	Extended dosing intervals, flexible administration
Teva	ARISTADA INITIO	Emerging	Fixed dose, easier administration
Indivior	PERSERIS	Niche	Autoinjector design

Market Share & Growth Trends
Despite Janssen’s dominance, PERSERIS's unique autoinjector targeting patient convenience positions it for niche market capture, especially among younger patients and clinics preferring minimal healthcare provider involvement.

4. Regulatory and Payer Policies

Increased reimbursement for LAIs and shifting policies favoring adherence improvements bolster PERSERIS's market penetration. CMS and private insurers are incentivizing long-acting formulations through reduced hospitalization costs.

5. Market Entry and Distribution Channels

Distribution relies heavily on clinics, hospitals, and specialized psychiatric service providers. Strategically partnering with major healthcare systems enhances reach.
