  • $70M Series B closed: Oversubscribed round funds lead candidate W101 into Phase 1 by end of 2027, plus a second near-development-candidate program and possibly a third.
  • Adipose-targeted siRNA licensed from China: Moonwalk licensed adipose-targeting chemistry from Sirius (Suzhou) Biotechnology, adding it to sequences against novel genetic targets discovered via Feng Zhang's genome-perturbation platform.
