PML is a rare, often severe demyelinating disease of the central nervous system caused by reactivation of latent JC virus in patients with compromised immunity. Growing global patient populations with HIV/AIDS, multiple sclerosis, organ transplants, autoimmune diseases, and hematological malignancies significantly contribute to rising PML susceptibility.

Pharmaceutical innovation is accelerating as companies explore antiviral agents, immune-reconstitution strategies, monoclonal antibodies, and novel JCV-targeted therapies. Improved diagnostic tools-including advanced MRI, CSF testing, and next-generation JCV detection assays-are also enhancing early disease identification and treatment decision-making.

Key Market Numbers (2024-2034)
• 2024 Market Size: USD 1.39 billion
• 2034 Market Forecast: USD 2.62 billion
• CAGR (2025-2034): 6.8%
• Largest Market: North America
• Fastest-growing Region: Asia Pacific

Market Drivers
1. Increasing Use of Immunosuppressive & Biologic Therapies
Patients on monoclonal antibodies and immunomodulators-such as those used for multiple sclerosis, Crohn's disease, psoriasis, and rheumatoid arthritis-face elevated risk of JC virus reactivation, expanding the patient-monitoring market.
2. Rising Prevalence of HIV/AIDS & Hematological Diseases
Growing populations with weakened immune systems contribute directly to higher PML incidence, especially in developing regions.
3. Advancements in JC Virus Diagnostic Tools
Enhanced MRI capabilities, ultrasensitive CSF viral-load assays, and molecular testing are enabling earlier detection and reducing mortality.
4. Strong Pipeline Research into Antiviral & Immunotherapeutic Options
Research targeting viral replication, immune reconstitution, and neuroprotection is intensifying as companies aim to reduce disease progression and improve survival rates.
5. Growing Demand for Neurology Specialty Care
The global expansion of neurology clinics and transplant centers is supporting better monitoring and management of high-risk populations.
