When Thomas Braun was starting out as a young professor at Germany’s University of Würzburg in 1997, he decided to try his hand at a new field: heart regeneration, a sci-fi-esque premise that could offer a way to treat patients recovering from a heart attack. He thought it would take a few years before they got results.

“We were,” he acknowledges now, “rather naïve.”

But on Thursday, after two and a half decades of fitful starts and abandoned leads, Braun and a team of researchers at the Max Planck Institute showed that they could reprogram heart cells in mice and get the animals to regenerate cardiac tissue after a heart attack. The breakthrough, published in Science, adds new evidence that it will eventually be possible to help patients recover muscle lost in heart attacks and gives another boon to anti-aging researchers who want to one day apply these rejuvenation techniques across much of the body.

In an attempt to get its house of accelerated approvals in order, the FDA is holding its second adcomm of 2021 to review cancer drugs that won accelerated approvals but failed to confirm clinical benefit in subsequent trials or have taken a long time to read those data out.

On Dec. 2, the FDA’s Oncologic Drugs Advisory Committee will review two accelerated approvals from Secura Bio’s Farydak (panobinostat), a third-line multiple myeloma drug, and Acrotech Biopharma’s Marqibo, as a third-line drug for adult patients with Philadelphia chromosome negative acute lymphoblastic leukemia. Both drugs have been marketed for more than five years under their accelerated approvals but have recorded negligible sales in their respective indications in recent years.

Bluebell Capital Partners, a proxy brawler fresh off a campaign to oust global food giant Danone’s CEO and most of its board of directors, has bought a stake in UK drugmaker GlaxoSmithKline with its eyes trained directly on Emma Walmsley, the Financial Times reported Wednesday.

The London-based hedge fund joins another notorious activist firm in Paul Singer’s Elliott Management, which earlier this year called for a shakeup in leadership at GSK to handle what the company described as a wealth of riches across the drug giant’s portfolio hindered by limited vision from top staff.
