the amount of money and expertise that it took to actually get a drug into the clinic was well beyond what you could do in an academic setting. I wanted to do translational medicine. Instead of just making a diagnosis and consoling a family, I wanted to help pioneer some new therapies that actually helped people. And ironically, I was thinking about this, and out of the blue I got a phone call from Richard Moscicki [the former chief medical officer of Genzyme].
X: After a decade rising through the ranks at Genzyme, you left for a struggling, small biotech, AVI Biopharma, in 2011—why?
EK: I originally came in as this internal consultant; they weren’t sure what to do with me. But I ended up having more and more programs and by the time I left, my team had had five drugs approved, which is incredibly exciting. When Sanofi took over Genzyme [in 2011], I really wanted to have the position of chief medical officer, to be in charge. I was ready. Genzyme had previously looked at both [Duchenne drug developer] Prosensa and AVI. We really liked the chemistry [at AVI], but we thought the management team was crazy so we didn’t do a deal with them. Yet when I was considering moving out of Sanofi and this opportunity came in to work there, I said I like the chemistry, I think there’s something there.
X: AVI was then renamed Sarepta, and management problems followed. How did you end up as CEO?
EK: I had told the board I had major problems [with the management of Sarepta]—as an officer of the company, I felt an obligation I had to let them know. And they said if you leave the whole company, it’s going to fall, what would it take to keep you here? I said, well, let me run the company and let me get us back on track. Unbeknownst to me, the entire senior management team had said we will leave, but if you name Ed as the CEO then we’ll stay with him. So it was a unique opportunity that, in essence, I had this oath of allegiance from the entire senior management team.
X: Were you always on board with the idea of seeking accelerated approval of eteplirsen off of such a small trial?
EK: That was a very controversial discussion point within Sarepta itself. Around 2012, there was such enthusiasm about a drug for Duchenne that could actually make dystrophin [the muscle-boosting protein that patients lack] that I think everybody— even the FDA to some extent—got ahead of themselves.
Once the FDA made the statement that they would be open to considering an approval filing based on 12 patients, once you say something like that, there’s no way that a CEO (and at the time it wasn’t me) or a board member would say “no, go back and do a placebo-controlled Phase 3 study.” The die was cast, and I think it would’ve been very difficult for the patients to accept it once there was this glimmer of hope.
But we knew that it would be challenging, we knew it would be an uphill battle at the FDA, and we also knew it would be challenging for reimbursement.
X: Looking back, is there anything you would have done differently?
EK: We did the best we could with a limited dataset. It was an iterative process. Even though it was challenging, in the end it was the right thing to do. If we went back to 2011, would I have done things differently if I had been CEO at the time? Yeah, I would’ve done that Phase 3 trial. But the decisions that were made were based on the information they had at the time. They weren’t bad decisions, but they proved to be more challenging than people had assumed.
X: What do critics within biotech circles say to you about it?
EK: I understand why people were critical, but people didn’t really understand the complexity of the story and how difficult it was. We tried to get as much information as we could and tried to supplement it as best as we could. One CEO of a biotech company—I won’t tell you which one—said “first I thought you were crazy, and then I realized you actually know what you were doing, you know about clinical development, you’re not some crazy guy.” It wasn’t just a wild and crazy path dictated by patient pressure. In fact, there was a lot of data that suggested that this drug was working. And the proof in the pudding is that the experts in the world are prescribing it, and people are interested in taking it—when you have a drug that doesn’t work, people don’t buy it.
X: What lessons do you take from the experience?
EK: Going forward, I would make sure that I have a clinical development program that would meet the needs not only of the regulatory authorities, but the payers. The days when, just because it is a rare disease you can command any drug price, are going to be gone. You’re going have to demonstrate there is a significant improvement in the quality of life for these people. What are the instruments that demonstrate that you’re making things better? That’s what I’ve been thinking a lot about, because I’ve been concerned that the science is outstripping our ability to pay for it.
X: Why did you leave Sarepta and go to a startup?
EK: Sarepta is much more of a commercial stage company now. What I really liked is the development—picking a target, taking it into the clinic, and going through the approval process. I like these difficult problems when it comes to developing therapies for patients, and I really wanted to do it one more time.
Adrian Krainer contacted me and said he has a new way of regulating RNA and making more proteins [at Stoke]. It’s very elegant science, and looks like a really good way to make therapies for diseases that aren’t going be easily amenable to gene therapy. Right now I’m trying to sit down with the team and figure out what diseases [to target]. We’ll be announcing a Series B soon. It’s an exciting time. For me, the interest is we have enough money to take a whole new platform into the clinic, and there aren’t too many times that people offer you that.
X: You worked with Henri Termeer while at Genzyme. Did you maintain a relationship with him after leaving?
EK: When I took over as CEO [of Sarepta] I asked Henri if he would be my adviser, and he was incredibly gracious. We would probably meet every month to go over any issues I was having. And I remember he would always say, “This is my advice, but you’re sitting in the corner office and it’s your decision. It’s not my decision.” He was someone I could trust and talk about problems and challenges with. He really helped me.
At the Xconomy Awards [Gala, in September in Boston] Belinda Termeer was there, Henri’s widow. And after the awards she came up to me and said, “you know, Henri would be so proud of you now.” And as I thought about it, that was probably true—he was very proud of his people. There are over 60 presidents and CEOs now that are ex-Genzyme. It was that culture of, “just because it hasn’t been done before, doesn’t mean you can’t do it.”
