Moderna Receives FDA Fast Track Designation for Respiratory Syncytial Virus (RSV) Vaccine (mRNA-1345)
“We are pursuing an mRNA RSV vaccine to protect the most vulnerable populations – young children and older adults,” said
Respiratory syncytial virus is a common respiratory virus that generally causes cold-like symptoms. In
Fast Track is designed to facilitate the development and expedite the review of therapies and vaccines for serious conditions and that fill an unmet medical need. Programs with Fast Track designation may benefit from early and frequent communication with the FDA, in addition to a rolling submission of the marketing application. The Company previously received Fast Track designation for its COVID-19 vaccine candidate, Zika vaccine candidate (mRNA-1893), methylmalonic acidemia (MMA) (mRNA-3704) and propionic acidemia (PA) (mRNA-3927) programs.
The Phase 1 study of mRNA-1345 to evaluate the tolerability and reactogenicity of mRNA-1345 in younger adults, older adults and children is ongoing. All four cohorts of younger adults (ages 18-49 years) are fully enrolled. Dosing in the older adult cohort (ages 65-79 years) is ongoing. The age range of toddlers in this de-escalation Phase 1 study is 12-59 months. The Company shared the first interim analysis of the Phase 1 study of mRNA-1345, through 1-month post-vaccination, of the younger adult cohorts at its annual Vaccines Day on
The Company also intends to evaluate the potential of combinations of mRNA-1345 with its vaccines against other respiratory pathogens in children and separately in older adults.
mRNA-1345 is a vaccine against RSV encoding for a prefusion F glycoprotein, which elicits a superior neutralizing antibody response compared to the postfusion state. RSV is the leading cause of respiratory illness in young children. Older adults (65+) are at high risk for severe RSV infections. mRNA-1345 uses the same lipid nanoparticle (LNP) as Moderna’s authorized COVID-19 vaccine and contains optimized protein and codon sequences.
In 10 years since its inception,
Moderna’s mRNA platform builds on continuous advances in basic and applied mRNA science, delivery technology and manufacturing, and has allowed the development of therapeutics and vaccines for infectious diseases, immuno-oncology, rare diseases, cardiovascular diseases and auto-immune diseases. Today, 24 development programs are underway across these therapeutic areas, with 16 programs having entered the clinic.
