AI brief of an SEC Form 8-K · Collegium Pharmaceutical (COLL)

Collegium Pharmaceutical chairman and director to retire; Gino Santini named next chair

Neutral Impact 3 of 5 leadership Written later

Collegium Pharmaceutical said founder and Chairman Michael Heffernan and director Gwen Melincoff will not stand for re-election at the 2025 Annual Meeting. The board named lead independent director Gino Santini as Chairman effective after that meeting, and the company said the departures are part of board refreshment and succession planning, not a disagreement. The filing also announced David Dieter as Executive Vice President and General Counsel, effective March 17, 2025.

Key points

  • Michael Heffernan, founder and Chairman, advised the board on March 11, 2025 that he will retire at the Annual Meeting; he has served on the board since October 2003
  • Gwen Melincoff, a director since 2017, will also retire at the Annual Meeting
  • Gino Santini, lead independent director since 2018, becomes Chairman effective immediately after the Annual Meeting
  • Dr. Carlos Paya was nominated on March 14, 2025 to stand for election at the Annual Meeting; David Dieter became General Counsel on March 17, 2025
