Likelihood of approval
62.3% vs 58.3% industry baseline
If approved by FDA: likely 2028–2030
Steps remaining: NDA/BLA submission
Confidence: High
Why this estimate
  • Baseline phase 3 → approval rate +58.3pp
    Industry-wide phase 3 drugs reach approval ~58.3% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).
  • Immunology slight uplift +1.0pp
    Mature endpoint landscape (ACR, DAS28, PASI) makes immunology approvals slightly more predictable.
  • Big-pharma sponsor +3.0pp
    Sanofi Pasteur, a Sanofi Company is a top-20 pharma sponsor — historical approval rates run ~3pp above average due to scale, regulatory experience, and trial-design quality.

Mechanism of action

The vaccine contains weakened (attenuated) strains of measles, mumps, and rubella viruses that trigger the body's adaptive immune system to produce antibodies and cellular immunity against these three viral pathogens. Upon vaccination, the attenuated viruses replicate minimally in the host, sufficient to generate protective immunity without causing disease. This provides long-term protection against natural infection with wild-type measles, mumps, and rubella viruses.
