GSK chief steps down in stunning move
GSK

The first woman to helm a Big Pharma will be stepping down in January as GSK’s Emma Walmsley moves aside for her chief commercial officer Luke Miels. Walmsley, 56, who became the British pharma’s CEO back in 2017, will officially leave Jan. 1, 2026. Back in 2021, Walmsley took a major decision to de-merge GSK’s consumer health unit Haleon, leaving the Big Pharma's biopharma and vaccines divisions to stand on their own. While Walmsley had the support and confidence of GSK’s board, activist investment group Elliott Management started calling for change at the top, citing “years of under-management.”
Miels, 50, has been CCO at GSK since 2017, having global responsibility for medicines and vaccines as well as being “instrumental,” according to GSK, in building the company's specialty medicines portfolio, notably in oncology and respiratory. He previously served stints at Roche, Sanofi and AstraZeneca. Story
Cue queues up CEO transition
Cue Biopharma
Cue Biopharma’s CEO Daniel Passeri has passed the baton after nine years at the helm, transitioning to a strategic advisor role as experienced CEO Usman “Oz” Azam, M.D., takes over. Azam comes to Cue fresh off of a two-year stint as CEO of Inspirna, the most recent in a string of CEO positions across a handful of biotech companies. The exec’s 25-year-long industry background also includes cell and gene therapy leadership at Novartis, making him a fit to shepherd the growth of T-cell-focused Cue and its CUE-401, a tolerogenic biologic Azam thinks could “disrupt the standard of care” in autoimmune disease.
