Moderna has announced the results of a Phase 3 trial evaluating the efficacy of mRNA-1647, its investigational cytomegalovirus (CMV) vaccine.
The study did not meet its primary endpoint of preventing CMV infection in seronegative female participants of childbearing age (16-40 years).
"The announcement is disappointing for families and healthcare professionals who have been eagerly awaiting a CMV vaccine to prevent congenital CMV, a leading infectious cause of birth defects," said Stéphane Bancel, Chief Executive Officer of Moderna.
As a result, Moderna will discontinue its congenital CMV clinical development program.
