Sanofi’s stunning CEO switch
Sanofi
Sanofi is replacing CEO Paul Hudson with Merck KGaA leader Belén Garijo, M.D., Ph.D., after a series of R&D setbacks at the French pharma. Hudson will end his six-year run at Sanofi’s helm Feb. 17, at which point Olivier Charmeil, executive vice president of general medicines, will step in as interim CEO until Garijo arrives April 29. Sanofi has struggled during Hudson’s tenure, with the ousted CEO himself acknowledging the Big Pharma has “had some challenges” on an earnings call with journalists late last month.
Garijo had a prior stint at Sanofi, during which she led the integration of Genzyme, before leaving to join Merck KGaA in 2011. She became Merck’s CEO in 2021. The initial reaction to the CEO change was “very negative,” analysts at Jefferies wrote in a note to clients. The French pharma’s stock was trading down nearly 5% in premarket trading Thursday. Story
CSL drops CEO amid plummeting profits
CSL
CSL is looking to turn its sales struggles around without the help of three-year CEO Paul McKenzie, Ph.D. The leader’s abrupt retirement was disclosed the day before the company unveiled its recent financial results Wednesday, citing a mutual determination that “now is the right time for new leadership,” former CEO and Board Chairman Brian McNamee said. McNamee further explained that the board came to the conclusion that McKenzie “didn’t have the skills that we wanted for the future,” he said in a call with analysts, as quoted by Bloomberg.
McKenzie came to CSL from Biogen in 2019, serving first as chief operating officer before his promotion to CEO in 2023, which came a few weeks after CSL’s landmark FDA approval for hemophilia B gene therapy Hemgenix. As CSL searches for a permanent successor, it has placed longtime company veteran Gordon Naylor in the interim CEO seat. Naylor has been with CSL for 33 years in various executive positions and looks to help the company recover from financial declines that saw its net profit sink from $2 billion in the second half of 2024 to $384 million over the same period in 2025, which was attributed to restructuring write-offs and other factors.

Helus appoints new CEO in ‘pivotal moment’
Helus Pharma
After last year’s rebrand from Cybin to Helus Pharma, the Toronto-based clinical stage pharmaceutical company, focused on psilocybin treatment, has named Michael Cola as CEO. The leadership change follows a switch from the NYSE to the Nasdaq Global Market, where Helus’ stock has lost a quarter of its value between Jan. 14 and Feb. 12. Cola brings 30 years of experience in neuroscience, rare disease and specialty pharmaceuticals and was most recently CEO of Avalo Therapeutics, where he led a transition to rare disease and genomic medicine.
Previously, Cola was president of the specialty pharmaceutical business at Shire (acquired by Takeda) when ADHD blockbuster Vyvanse helped grow Shire from $5 billion to $20 billion in market capitalization. Helus called the leadership shift a “pivotal moment” as the company looks to advance its pipeline of mental health therapies. Release
