 Chutes and LaddersWelcome to this week's Chutes & Ladders, our roundup of significant leadership hirings, firings and retirings across the industry. Please send the good word—or the bad—from your shop to Gabrielle Masson and it will be featured here at the end of each week.


Gilead's CMO bids adieu

Gilead Sciences is saying goodbye to its chief medical officer after Merdad Parsey, M.D., Ph.D., announced intentions to leave the company early next year.

As Gilead hunts for a successor, Parsey will continue to serve as CMO until the first quarter of 2025. The outgoing exec also plans to support the transition of his replacement over the next several months, Gilead said in a release. Parsey has been at Gilead for five years, joining in November 2019.

During his stint at the company, Parsey helped lead the growth of Gilead’s development organization, including the establishment of Gilead’s cancer pipeline and the rollout of the COVID-19 treatment Veklury. The oncology portfolio has suffered some setbacks in recent months, however, with Gilead dropping work on magrolimab in April despite the anti-CD47 monoclonal antibody being the centerpiece of its $4.9 billion acquisition of Forty Seven.

“It has been a privilege to lead the development team, especially as we have worked to deliver transformative medicines for people with HIV, COVID-19 and cancer,” Parsey said in a statement. “I am profoundly excited about the work we have done to build a strong, diverse clinical pipeline that has tremendous potential to deliver on our commitment to improve health for people around the world.” Release 


Cassava execs are out

Austin, Texas-based Cassava Sciences is searching for a permanent leader in the wake of the resignation of CEO Remi Barbier. 

The Alzheimer's-focused company, which is no stranger to controversy, has found an interim helmsman in Richard Barry, who has been tapped as executive chairman of the board and Cassava’s principal executive officer, effective immediately. Barry has served as director of Cassava since June 2021 and has also served as director of Sarepta Therapeutics since June 2015.

At the same time, the company will search for a new permanent CEO, Cassava said in a press release. Barbier is set to remain onboard with Cassava until Sept. 13 in a non-executive capacity, without duties or responsibilities.

In addition, Lindsay Burns, Ph.D., SVP of neuroscience, has agreed to step down from her role at Cassava. After being separated from the company for a year, Burns will offer consulting services to Cassava, providing information and support for scientific research and obtaining approval for the company’s products.
