Note on Biologic Patents

Matching patents to biologic drugs is far more complicated than for small-molecule drugs.

DrugPatentWatch employs three methods to identify biologic patents:

1. Brand-side disclosures in response to biosimilar applications

These patents were identified from disclosures by the brand-side company, in response to a potential biosimilar seeking to launch. They have a high certainty of blocking biosimilar entry. The expiration dates listed are not estimates — they're expiration dates as indicated by the brand-side company.

2. DrugPatentWatch analysis and brand-side disclosures

These patents were identified from searching drug labels and other general disclosures from the brand-side company. This list may exclude some of the patents which block biosimilar launch, and some of these patents listed may not actually block biosimilar launch. The expiration dates listed for these patents are estimates, based on the grant date of the patent.

3. Patents from broad patent text search

For completeness, these patents were identified by searching the patent literature for mentions of the branded or ingredient name of the drug. Some of these patents protect the original drug, whereas others may protect follow-on inventions or even inventions casually mentioning the drug. The expiration dates listed for these patents are estimates, based on the grant date of the patent.

What Are the Key Market Drivers for the Adjuvanted RSV Vaccine?

1. Growing Burden of RSV Disease Globally
RSV causes substantial morbidity and mortality, particularly in infants, older adults, and immunocompromised populations. WHO estimates attribute approximately 66,000–199,000 annual deaths among children under 5 years, with significant hospitalization costs in the elderly (2). The rising prevalence among high-risk groups drives demand for more effective vaccines.

2. Advances in Vaccine Technology and Adjuvant Development
The incorporation of novel adjuvants into RSV vaccines aims to elicit stronger and longer-lasting immune responses. Trials with adjuvanted vaccines, such as Novavax's RSV F nanoparticle (not yet adjuvanted but indicating interest), highlight the industry's focus on potentiating efficacy, especially in the elderly (3).

3. Regulatory Endorsements and Accelerated Approvals
Regulatory agencies like the FDA and EMA are facilitating faster review pathways, recognizing RSV’s public health impact. The FDA’s recent approval of the first RSV monoclonal antibody for prevention in high-risk infants (Palivizumab) exemplifies market recognition (4). Similar pathways for vaccines can expedite adoption.

4. Increasing Awareness and Vaccination Initiatives
Public health campaigns emphasizing respiratory disease prevention, coupled with recommendations from bodies like CDC and WHO, boost vaccination rates, particularly in vulnerable groups.
