Ego, Ambition, and Turmoil: Inside One of Biotech’s Most Secretive Startups

CAMBRIDGE, Mass. — At first glance, Moderna Therapeutics looks like the most enviable biotech startup in the world. It has smashed fundraising records and teamed up with pharmaceutical giants as it pursues a radical plan to revolutionize medicine by transforming human cells into drug factories.

But the reality is more complicated.

A STAT investigation found that the company’s caustic work environment has for years driven away top talent and that behind its obsession with secrecy, there are signs Moderna has run into roadblocks with its most ambitious projects.

At the center of it all is Stéphane Bancel, a first-time biotech CEO with an unwavering belief that Moderna’s science will work — and that employees who don’t “live the mission” have no place in the company. Confident and intense, Bancel told STAT that Moderna’s science is on track and, when it is finally made public, that it will meet the brash goal he himself has set: The new drugs will change the world.

But interviews with more than 20 current and former employees and associates suggest Bancel has hampered progress at Moderna because of his ego, his need to assert control and his impatience with the setbacks that are an inevitable part of science. Moderna is worth more than any other private biotech in the US, and former employees said they felt that Bancel prized the company’s ever-increasing valuation, now approaching $5 billion, over its science.

As he pursued a complex and risky strategy for drug development, Bancel built a culture of recrimination at Moderna, former employees said. Failed experiments have been met with reprimands and even on-the-spot firings. They recalled abusive emails, dressings down at company meetings, exceedingly long hours, and unexplained terminations.

At least a dozen highly placed executives have quit in the past four years, including heads of finance, technology, manufacturing, and science. In just the past 12 months, respected leaders of Moderna’s cancer and rare disease programs both resigned, even though the company’s remarkable fundraising had put ample resources at their disposal. Each had been at the company less than 18 months, and the positions have yet to be filled.

Lower-ranking employees, meanwhile, said they’ve been disappointed and confused by Moderna’s pivot to less ambitious — and less transformative — treatments. Moderna has pushed off projects meant to upend the drug industry to focus first on the less daunting (and most likely, far less lucrative) field of vaccines — though it is years behind competitors in that arena.

The company has published no data supporting its vaunted technology, and it’s so secretive that some job candidates have to sign nondisclosure agreements before they come in to interview. Outside venture capitalists said Moderna has so many investors clamoring to get in that it can afford to turn away any who ask too many questions. Some small players have been given only a peek at Moderna’s data before committing millions to the company, according to people familiar with the matter.

“It’s a case of the emperor’s new clothes,” said a former Moderna scientist. “They’re running an investment firm, and then hopefully it also develops a drug that’s successful.”

Like many employees and former employees, the scientist requested anonymity because of a nondisclosure agreement. Others would not permit their names to be published out of fear that speaking candidly about big players in the industry would hurt their job prospects down the road.

Moderna just moved its first two potential treatments — both vaccines — into human trials. In keeping with the culture of secrecy, though, executives won’t say which diseases the vaccines target, and they have not listed the studies on the public federal registry, ClinicalTrials.gov. Listing is optional for Phase 1 trials, which are meant to determine if a drug is safe, but most companies voluntarily disclose their work.

Investors say it’ll be worth the wait when the company finally lifts the veil.

“We think that when the world does get to see Moderna, they’re going to see something far larger in its scope than anybody’s seen before,” said Peter Kolchinsky, whose RA Capital Management owns a stake in the company.

Bancel, meanwhile, said he is aware of the criticism of him and has taken some steps to address it. After scathing anonymous comments about Moderna’s management began showing up online, Bancel went to Silicon Valley to get tips on employee retention from the human resources departments of Facebook, Google, and Netflix. But he makes no apologies for tumult past or present, pointing to the thousands of patients who might be saved by Moderna’s technology.

“You want to be the guy who’s going to fail them? I don’t,” he said in an interview from his glassy third-floor office. “So was it an intense place? It was. And do I feel sorry about it? No.”

An ambitious CEO dreams big

Bancel, 44, had no experience running a drug development operation when one of biotech’s most successful venture capitalists tapped him to lead Moderna. He’d spent most of his career in sales and operations, not science.

But he had made no secret of his ambition.

A native of France, Bancel earned a master’s in chemical engineering from the University of Minnesota and an MBA from Harvard in 2000. As Harvard Business School classmates rushed to cash in on the dot-com boom, Bancel laid out a plan to play “chess, not checkers.”

“I was always thinking, one day, somebody will have to make a decision about me getting a CEO job,” he told an audience at his alma mater in April. “… How do I make sure I’m not the bridesmaid? How do I make sure that I’m not always the person who’s almost selected but doesn’t get the role?”

He went into sales and rose through the operational ranks at pharmaceutical giant Eli Lilly, eventually leading the company’s Belgian operation. And in 2007, at just 34, he achieved his goal, stepping in as CEO of the French diagnostics firm bioMérieux, which employs roughly 6,000 people.

The company improved its margins under Bancel’s tenure, and he developed a reputation as a stern manager who got results, according to an equities analyst who covered bioMérieux at the time.

“He doesn’t suffer fools lightly,” the analyst said, speaking on condition of anonymity to comply with company policy. “I think if you’re underperforming, you’ll probably find yourself looking for another job.”

Bancel’s rise caught the eye of the biotech investment firm Flagship Ventures, based here in Cambridge. Flagship CEO Noubar Afeyan repeatedly tried to entice him to take over one of the firm’s many startups, Bancel said. But he rejected one prospect after another because the startups seemed too narrow in scope.

Moderna was different.

The company’s core idea was seductively simple: cut out the middleman in biotech.
