Novavax: da EMA ok al vaccino proteico adiuvato aggiornato alle varianti. Novavax annuncia che il Comitato per i medicinali per uso umano (CHMP) di EMA ha espresso parere positivo per Nuvaxovid™ XBB.1.5 il vaccino proteico adiuvato aggiornato alle varianti per la prevenzione di Covid-19 negli individui a partire dai 12 anni di età.
In particolare, il vaccino aggiornato ha dimostrato la sua efficacia nel generare risposte anticorpali neutralizzanti contro le nuove sottovarianti emergenti del virus. John C. Jacobs, Presidente e Amministratore Delegato di Novavax, ha così commentato la notizia: “A seguito del parere positivo del CHMP e dell’attesa decisione della Commissione Europea, Novavax lavorerà a stretto contatto con gli Stati membri dell’UE per raggiungere l’obiettivo comune di rendere presto disponibile un vaccino COVID-19 non-mRNA aggiornato a base proteica in Europa”.
Ciò è particolarmente importante alla luce dell’aumento dei casi di COVID-19 osservato in più della metà dei Paesi UE/SEE, come riportano le parole di Giuseppe Bunone, Country Director, Commercial operations di Novavax Italia che ha dichiarato: “Il parere positivo da parte del CHMP di EMA per il nostro vaccino aggiornato contro le nuove varianti è un passo importante che arriva proprio in un momento delicato in cui in tutta Europa, Italia inclusa, stiamo assistendo ad un aumento dei casi di Covid-19 e dei ricoveri. Grazie a questa decisione sarà presto disponibile anche in Italia un vaccino proteico ricombinante adiuvato che ben si presta ad un contesto endemico grazie ai numerosi vantaggi che offre in termini di conservazione, trasporto e gestione. La vaccinazione, lo abbiamo visto, rimane uno dei migliori strumenti per proteggerci dalle sfide legate alle varianti. È dunque importante continuare a vaccinarsi, in particolare per le persone con comorbidità e a rischio”.

Novavax’s Updated Nuvaxovid™ COVID-19 Vaccine Receives Positive CHMP Opinion in the EU
• Pending a European Commission decision, Novavax’s vaccine will be the only updated protein-based non-mRNA COVID-19 vaccine available in Europe for individuals aged 12 and older
GAITHERSBURG, Md., October 31, 2023 – Novavax, Inc. (Nasdaq: NVAX), a global company advancing protein-based vaccines with its Matrix-M™ adjuvant, today announced that the Nuvaxovid™ XBB.1.5 dispersion for injection COVID-19 Vaccine (recombinant, adjuvanted) (NVX-CoV2601) has been recommended for approval for active immunization to prevent COVID-19 caused by SARS-CoV-2 in individuals aged 12 and older in the European Union by the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency. The European Commission will review the CHMP recommendation and is expected to make a final decision in the coming days.
“Following the positive CHMP opinion and pending European Commission decision, Novavax will work closely with EU member states on our shared goal of delivering an updated protein-based non-mRNA COVID-19 vaccine in Europe,” said John C. Jacobs, President and Chief Executive Officer, Novavax.
The CHMP positive opinion was based on non-clinical data showing that Novavax’s updated COVID-19 vaccine induced functional immune responses against XBB.1.5, XBB.1.16 and XBB.2.3 variants. Additional non-clinical data demonstrated that Novavax’s vaccine induced neutralizing antibody responses to newly emerging subvariants BA.2.86, EG.5.1 FL.1.5.1 and XBB.1.16.6 as well as CD4+ polyfunctional cellular (T-cell) responses against EG.5.1 and XBB.1.16.6. These data indicate Novavax’s vaccine can stimulate both arms of the immune system and may induce a broad response against circulating variants.1,2
In clinical trials, the most common adverse reactions associated with Novavax’s prototype COVID-19 vaccine (NVX-CoV2373) included headache, nausea or vomiting, muscle pain, joint pain, injection site tenderness, injection site pain, fatigue and malaise.
Novavax’s vaccine is authorized for use in the U.S. and is currently under review in other markets.

About Nuvaxovid™ XBB.1.5 2023-2024 Formula (NVX-CoV2601)
NVX-CoV2601 is an updated version of Novavax’s prototype COVID-19 vaccine (NVX-CoV2373) formulated to target the Omicron XBB.1.5 subvariant. It is a protein-based vaccine made by creating copies of the surface spike protein of SARS-CoV-2 that causes COVID. With Novavax’s unique recombinant nanoparticle technology, the non-infectious spike protein serves as the antigen that primes the immune system to recognize the virus, while Novavax’s Matrix-M™ adjuvant enhances and broadens the immune response. The vaccine is packaged as a ready-to-use liquid formulation and is stored at 2° to 8°C, enabling the use of existing vaccine supply and cold chain channels.
About Matrix-M™ Adjuvant
When added to vaccines, Novavax’s patented saponin-based Matrix-M adjuvant enhances the immune system response, making it broader and more durable. The Matrix-M adjuvant stimulates the entry of antigen-presenting cells at the injection site and enhances antigen presentation in local lymph nodes.
