- AstronauTx hired Michelle Mellion as chief medical officer, adding her to the company's executive team
- Michelle Mellion previously held the same CMO role at PepGen and EveryONE Medicines before joining AstronauTx
Why it matters: AstronauTx is staffing its top medical position with a leader who has already held the CMO title at two other biotechs, suggesting the company is leaning on prior drug-development experience to advance its pipeline. The hire continues a pattern of lateral CMO moves across small biotechs.
