Good day. Expedition Therapeutics is taking a big swing: The startup is going up against top pharmaceutical companies to field its own drug for chronic obstructive pulmonary disease, a lung condition that causes 6% of deaths globally. Among those heavyweights are GSK and Boehringer Ingelheim.
Even on existing medications, COPD patients can have flare-ups, or “exacerbations,” that can land them in the hospital. Expedition is offering a once-daily pill that inhibits an enzyme called DPP1 to quell inflammation stemming from neutrophils. Neutrophils, the most-common type of white blood cell, are known as the immune system’s first responders–performing roles such as fighting infections. In the lungs of COPD patients, however, they become dysregulated and lead to inflammation.
San Francisco-based Expedition just raised $115 million in a Series B led by General Atlantic, money it will use to test the drug in global clinical trials of 600 patients.
Expedition Founder and Chief Executive Yi Larson previously was executive vice president and chief financial officer of Turning Point Therapeutics, a cancer drug developer that was acquired by Bristol Myers Squibb in 2022 for $4.1 billion. Before running biotechs, she was a managing director in healthcare investment banking at Goldman Sachs.
WSJ Pro spoke with Larson about Expedition’s effort to crack the COPD market. Here are excerpts from the conversation, edited for length and clarity.
WSJ Pro: Why did you target COPD with your latest venture?
Larson: Most of the treatments today are addressing symptoms. And some of the newer treatments that have been approved—the biologics—are a bit more targeted, but only treat a minority of the patients. In DPP1, we found this beautifully selective target. That's an opportunity to potentially help millions of people.
WSJ Pro: What are some of the difficulties of developing a new COPD treatment?
Larson: One of the challenges is these are larger trials with patients from all over the world. You've got to have really good clinical operations and execution globally. From your trial design [perspective]—that’s where sometimes in the past COPD trials have failed.
WSJ Pro: Your Series B round is smaller than your $165 million Series A last year. Why?
Larson: This is disciplined capital-raising and deployment. I was a banker at Goldman for many years and now have been an operator for some time. That's always been my approach: What's the right amount of capital at the appropriate moment in time.
WSJ Pro: How has the biotech venture financing market changed since last year?
Larson: Last year was very challenging. It does feel that things are a little bit better this year, although investors are still very disciplined and selective, which is a good thing.
WSJ Pro: What was it like to make the transition from banking to biotech entrepreneur?
Larson: Banking was a great training ground to be an operator. I was fortunate to have grown up in banking at a time when biotech was really growing at an accelerated pace, and I got to work with some of the best biotech companies and really learn from them– both what they were doing right and what wasn't going well. When I moved over to the operating side, it was really exciting to be able to take all those lessons learned and be able to implement them in my own companies.
