gene editing
Tome laying off practically entire staff
Tome Biosciences, a high-profile gene-editing startup, will lay off virtually its entire staff this fall, according to a legal notice filed Friday. The notice came a day after STAT reported the company was flailing.
Tome announced an incredible $213 million fundraise just last December — with grand ambitions to write the "final chapter in genomic medicines."
Its technology, called PASTE, was meant to write large sequences of DNA, allowing scientists to potentially replace entire genes or rewire cells — as opposed to making smaller changes. But there was concern about the technology's accuracy, as well as issues with intellectual property.

glp-1 drugs
This startup was way ahead of its time
Ooh, what an origin story. Jeffrey Flier, the former dean of Harvard Medical School, posted the above on X. In 1990 his GLP-1 company MetaBio "failed," he said — and you can see why a preprint that details why this blockbuster class of drugs was essentially shelved for decades. Part of the problem, he says, was the corporate structure in place, not the science.
Eli Lilly first had dibs on the GLP-1 work at MetaBio and abandoned it, in part due to "issues with irritation in animal toxicology work." Pfizer then expressed interest in MetaBio's work, but company leadership ultimately came to the baffling (and still unexplained) conclusion that "there would never be another injectable therapy for diabetes other than insulin."
"Sadly, MetaBio, the little company that could — and perhaps should have — been hugely successful with GLP-1, was a decade or more ahead of its time," Flier writes in the preprint. "Even the biggest blockbusters can be dismissed as unworthy by smart and ambitious people."
