In August 2020, Johnson & Johnson paid $6.5 billion cash to acquire Momenta Pharmaceuticals Inc. That strengthened J&J’s immune-mediated disease portfolio and grew its interest in autoantibody-driven disease therapies by bringing nipocalimab into the fold. Now the investment is paying off with top-line results of phase II and III studies that hit their primary endpoints using the fully human glycosylated monoclonal antibody targeting the human neonatal Fc receptor. The studies were in treating generalized myasthenia gravis and in Sjögren’s disease.
