  • Johnson & Johnson to acquire Momenta for $52.50 per share in cash, representing a total equity value of $6.5 billion and a 70% premium to Momenta’s closing price on August 18, 2020
  • Momenta’s FcRn inhibitor, nipocalimab, has the potential to transform treatment of autoantibody-driven autoimmune diseases
