(Alliance News) - Sanofi SA and GlaxoSmithKline PLC initiated a new phase 2 study with 720 volunteers to select the most appropriate antigen dosage for phase 3 evaluation of their adjuvanted recombinant protein Covid-19 vaccine candidate, both companies said on Monday.
In parallel to the new phase 2 study and recognising the global emergence of new SARS-CoV-2 variants and their potential impact on vaccine efficacy, Sanofi has commenced development work against new variants which will be used to inform the next stages of the Sanofi/GSK development programme.
"Over the past few weeks, our teams have worked to refine the antigen formulation of our recombinant-protein vaccine, based on learnings from our initial phase 1/2 study," said Thomas Triomphe, executive vice president & head of Sanofi Pasteur.
"We look forward to further progressing this vaccine candidate to phase 3 in the second quarter of 2021, if this phase 2 study is successful," added Roger Connor, president of GSK Vaccines.
Sanofi shares were trading 0.3% lower in Paris on Monday at EUR76.82 each, while GSK shares were up 0.7% in London at 1,223.10 pence each.
