Cosette Builds Legal Infrastructure for Acquisition-Led Growth

Cosette Pharmaceuticals is reinforcing the legal and compliance architecture underpinning its acquisition-driven expansion strategy, appointing Erika Tooman as Senior Vice President and General Counsel. The move signals that Cosette's Bridgewater, N.J.-based leadership is treating governance and risk management as operational priorities, not afterthoughts, as the company integrates new assets and pursues further portfolio growth.

Tooman brings more than two decades of pharmaceutical legal experience, most recently serving as Chief Legal Officer, Corporate Secretary, and Chief Compliance Officer at Radius Health, where she was involved in major litigation outcomes, royalty monetization transactions, and M&A activity. Earlier roles included senior leadership positions at Currax Pharmaceuticals and Pernix Therapeutics, and Senior Patent Counsel at Ikaria, where she contributed to exclusivity extensions ahead of that company's acquisition. At Cosette, she will oversee legal, compliance, governance, and risk management functions, and will serve as a strategic advisor to both the executive team and the Board of Directors.

Her dual grounding in law and life sciences -- Tooman holds a JD from Brooklyn Law School, a Master of Biotechnology from Columbia University, and a BA in Biology from Franklin and Marshall College -- positions her to engage directly with the regulatory and IP complexities that accompany specialty pharma portfolio transactions. She is admitted to practice in New York and New Jersey and is registered with the U.S. Patent and Trademark Office.

Cosette, backed by Avista Healthcare Partners and funds managed by Hamilton Lane, employs more than 350 staff across functional areas. President and CEO Apurva Saraf cited Tooman's capacity to navigate complexity during portfolio integration as central to her appointment. The hire reflects a broader pattern among PE-backed specialty pharma platforms: as deal cadence accelerates, in-house legal and compliance infrastructure must scale in parallel to manage transactional, regulatory, and governance exposure.
