Merck gets positive EU CHMP opinion for Pneumococcal vaccination in adults
Rahway: Merck, known as MSD outside of the United States and Canada, has announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) recommended the approval of CAPVAXIVE (Pneumococcal 21-valent Conjugate Vaccine) for active immunization for the prevention of invasive disease and pneumonia caused by Streptococcus pneumoniae in individuals 18 years of age and older.
The CHMP’s recommendation will now be reviewed by the European Commission (EC) for marketing authorization in the European Union (EU), Iceland, Liechtenstein and Norway, and a final decision is expected by the second quarter of 2025.
“Invasive pneumococcal disease and pneumococcal pneumonia remain critical public health challenges worldwide,” said Dr. Paula Annunziato, senior vice president, infectious diseases and vaccines, Global Clinical Development, Merck Research Laboratories. “This positive opinion is yet another testament to the clinical profile of CAPVAXIVE and brings us a step closer to helping protect adults in the EU against pneumococcal disease. Invasive pneumococcal disease can lead to serious consequences including hospitalization, organ damage and even death. We are pleased with the CHMP recommendation and look forward to the European Commission’s decision.”
CAPVAXIVE is specifically designed to help protect adults against the serotypes that cause the majority of invasive pneumococcal disease (IPD) cases. Based on country-level data from the following four EU countries, the serotypes covered by CAPVAXIVE are responsible for more cases of IPD in adults compared to PCV20 (pneumococcal 20-valent conjugate vaccine):
Coverage of Serotypes Responsible for IPD in Select EU Countries | ||||
Country | Age | Year Reported | CAPVAXIVE | PCV20 |
Germany | ≥60 | 2020 | ~84% | ~58% |
France | >65 | 2022 | ~85% | ~63% |
Italy | >65 | 2023 | ~77% | ~64% |
Spain | >65 | 2020 | ~82% | ~62% |
Data were included for select countries based on EU membership, population size and the most recent year reported. These values are based on country-level epidemiologic data and regional variations may exist; these values do not reflect the efficacy of the respective vaccines. There are currently no studies comparing the efficacy of CAPVAXIVE and PCV20.
Among the clinical data supporting the recommendation are results from the pivotal Phase 3 STRIDE-3 trial (NCT05425732), which evaluated CAPVAXIVE compared to PCV20 in adults 18 years of age and older who had not previously received a pneumococcal vaccine. The recommendation is also supported by results from the Phase 3 STRIDE-4 (NCT05464420), STRIDE-5 (NCT05526716), STRIDE-6 (NCT05420961), STRIDE-7 (NCT05393037) and STRIDE-10 (NCT05569954) trials, evaluating CAPVAXIVE in vaccine-naïve and vaccine-experienced adults.
If approved in the EU, it would mark the fourth authorization of CAPVAXIVE for the prevention of invasive pneumococcal disease and pneumococcal pneumonia in adults. CAPVAXIVE was first approved in the U.S. in June 2024, in Canada in July 2024, and in Australia in January 2025. In addition, CAPVAXIVE is currently under review in Japan, and other worldwide regulatory filings are underway.
