You're listening to Short Wave from NPR. Hey, Shortwavers. Emily Kwong here with NPR pharmaceuticals correspondent Sydney Lupkin.
Sydney Lupkin
Hello. Hi, Emily. So this weekend marked a very important anniversary.
Emily Kwong
Was it our anniversary? We have been friends for a long time.
Sydney Lupkin
No. Oh, not our friend. Iversary, Emily. The anniversary of a pill that revolutionized cancer care.
Emily Kwong
Oh, that's way better. Not that I don't love you. What pill?
Sydney Lupkin
So the drug is called Gleevec. And May 10 marks 25 years since the Food and Drug Administration first approved it.
Emily Kwong
Okay, so Gleevec. Why is this pill such a big deal?
Sydney Lupkin
Well, it's considered one of the first targeted cancer therapies. And what it really did was make some cancers that were once fatal, not so fatal anymore. Survivable. Wow.
Emily Kwong
That is a big deal.
Sydney Lupkin
Yeah. And I talked about it with this guy in Atlanta. His name is Mel Mann. And he told me that in 1995 he was dealing with some back pain and fatigue, but it wasn't really clear why. Then after an MRI showed what was going on with his bone marrow, he was diagnosed with chronic myeloid leukemia. Leukemia, A kind of blood cancer. He was 37 at the time and had a five year old daughter at home. The doctors told him he had three years to live.
Mel Mann
Yeah, I was shocked because, you know, that's the first time that I had to face my own mortality.
Sydney Lupkin
But Emily, Mel is actually still here.
Emily Kwong
That is amazing. After being given only three years to live. So how. How did that happen?
Sydney Lupkin
So after his diagnosis in January 1995, Mel starts doing bone marrow drives, hoping to a match and get a life saving bone marrow transplant. Yeah, but at the time, if you were black, you had such a low chance of finding a match that he knew it was kind of an impossibility.
Mel Mann
And I would take my daughter with me. So she understood that I needed a match to live. In fact, one of the drives, she could have been more than probably still five. She says, daddy, I can't see why you can't find a match. All the blood looks the same to me.
Sydney Lupkin
But after all this searching, Mel added thousands of people to the registry. But he didn't find a match for himself.
Mel Mann
Immediately, you're gonna think of your family. And I thought, you know how she's gonna be when at the end of three years and it was eight years, and I was trying to bargain for more.
Sydney Lupkin
So he started participating in clinical trials for experimental treatments still in development. They would work for a few months and then stop. He outlived his expiration but wasn't doing well.
Mel Mann
By then, I was like, really tired. You know, I was asleep for eight hours, drank two cups of coffee, wake up and felt like I never went to bed and become like, really lost a lot of weight. So I asked the doctor were there any more drugs?
Sydney Lupkin
And there was another one, Gleevec, though of course it was still being studied and didn't have that name yet. Mel started the drug in August of 1998. By the next June, Emily, he was running a marathon in Anchorage, Alaska.
Mel Mann
And I did it in a pretty decent time, too.
Emily Kwong

Emily Kwong
we are talking about a revolutionary cancer drug. Developing a new drug, of course, is not easy. So what is the origin story of this one?
Sydney Lupkin
GLEEVEC yeah, so it kind of starts with a setback. Oncologist Brian Drucker had this idea that at the time was really new in cancer medicine. He thought, what if instead of just trying to kill cancer cells and hoping that the healthy Cells were mostly spared. You could target the reason that cancer cells Were growing out of control in the first place.
Brian Drucker
What I saw with chemotherapy Is that we are giving patients Pretty toxic drugs. We didn't quite know if they'd work. And my view was there had to be a better way. And that better way had to be based on a knowledge that was driving the growth of a specific cancer.
Emily Kwong
I mean, it makes total sense and is a pretty widely accepted idea now. But you're saying back then, no one had ever tried this kind of targeted approach before?
Sydney Lupkin
We didn't because we didn't know what to target. There was a lot we didn't understand about cancers. And we learned it in chronic myeloid leukemia, which became one of the first cancers to be linked to a genetic abnormality, the lidelphia chromosome. Scientists knew that people with this chromosome Had a fused gene. That gene results in an abnormal enzyme that regulates One of the on, off switches for certain cell growth. This one gets stuck in the on position, Leading to uncontrolled white blood cell growth. Chronic myeloid leukemia. Brian was trying to turn that switch off, so he wanted to find a drug that would inhibit the abnormal enzyme.
Emily Kwong
That's brilliant. Yeah.
Brian Drucker
The problem was not a lot of people believe that was going to work.
Sydney Lupkin
He said that his institution thought it was an interesting idea For a grant or something, but he ultimately had to leave his job in Boston and move across the country to oregon health and science university to really actually pursue it.
Emily Kwong
Yeah, he's like, this is big science. I gotta take a risk here. Was it worth it?
Sydney Lupkin
Well, he says that within six weeks of arriving, he was testing five compounds from the drug company that would become novartis in his lab. One of them was gleevec. It was a compound discovered by scientist Nicholas lyden, and it worked, at least in the lab.
Brian Drucker
The reality is, I wasn't just a researcher. I also had patients. Many, many patients who believed in me, Thought that this was a potential way forward for them. And it allowed me to have enough courage to be their. Their mouthpiece and voice to lobby, to get this drug into clinical trials.
Emily Kwong
So it sounds like he was in a race against time, really, to try to save these patients lives.
Sydney Lupkin
Yeah, exactly. And these trials were also unique because they only included patients with this specific, specific kind of leukemia.
Emily Kwong
Wait, so was that not common in cancer drug trials? At the.
Insa Gothman
No.
Sydney Lupkin
Before this trial, cancer drug studies Would include patients with all kinds of cancer. And they just sort of hope that the drug worked for some of them.
Emily Kwong
They would just Lump them all together,
Sydney Lupkin
and for a few, it would become the standard of care. It would work. But for most people, the drug wouldn't work.
Emily Kwong
That's so interesting. But I guess Brian's trial, he. He wanted to focus just on this type of leukemia because his pill was designed to target that cancer and the thing causing the cancer.
Sydney Lupkin
Exactly.
Insa Gothman
Yeah.
Sydney Lupkin
Within six months, every cml, which is the abbreviation for chronic myeloid leukemia, Patient taking more than 300 milligrams responded to the treatment.
Emily Kwong
Every patient.
Sydney Lupkin
It was unheard of, Emily. And because it was 1999, it was also the early days of blogging and Internet chat room, so the patients were talking to each other.
Brian Drucker
So all of a sudden, I was getting contacted by patients from around the world who wanted to enroll in this clinical trial.
Sydney Lupkin
They knew that they had to scale up trials and get the drug application to regulators and, like, fast. And that's where the folks at Novartis come in.
Emily Kwong
That's the drug company, Right?
Sydney Lupkin
Right. So the next step would be for a drug company to take the drug to the FDA for approval. To do that, you've got to look at the data and prepare a whole package. Entered insa gothman, who was right out of school and got hired as a biostatistician.
Insa Gothman
And it was apparent back then that this is a game changer and that we needed people with energy who could make this drug development even faster and bringing this to authorities as fast as we could.
Sydney Lupkin
She became the statistical lead on the project, Working long hours.
Emily Kwong
What was she doing?
Sydney Lupkin
So one of her jobs was to look at survival curves.
Insa Gothman
And when I was first running them for gleevec, I was like, okay, I must have done a programming mistake. Something is wrong. Because the curves were just. I mean, they were all doing fantastic, and they were all alive. And I'm like, no, no, no. Something is wrong. This can't be. Can't be right.
Emily Kwong
But it was right.
Sydney Lupkin
Yeah. So gleevec was able to switch the enzyme to the off position, Shutting down that cell overgrowth, which let patients white blood cell counts return to normal.
Emily Kwong
This is so inspiring.
Sydney Lupkin
And when gleevec was approved on May 10, 2001, it was the fastest approval at the time. 72 days. And everyone from the NIH to the FDA to the HHS Secretary to the company executives wanted to take a bow. Amit sarpotwari is an assistant professor of population medicine at Harvard medical school. And he says he. It was an example of the public and private sectors working together at their best to bring forward meaningful medical advancements.
Brian Drucker
We have one of the most robust innovation systems in the world. And that system in pharmaceuticals really relies on early stage funding by the government of science of medical research.
Sydney Lupkin
And, emily, none of this would have happened without people knowing about the genetic mutation that causes this cancer in the first place. The philadelphia chromosome. That discovery was funded by the national cancer institute, which is part of the NIH.
Emily Kwong
So this, even though it got approved in 72 days, that's because of years of work ahead of it and layers of cooperation from so many different groups.
Sydney Lupkin
Cooperation and taking on risk. Remember, brian drucker moved across the country. The drug company that would become novartis Took on the financial risk of doing the expensive clinical trials. The patients took a risk trying a new drug. And then a whole bunch of people moved to heaven and earth to speed up the approval time. All of this changed medicine.
Brian Drucker
You can think of it as really ushering in this era that we have
Mel Mann
now
Brian Drucker
targeted therapies, Targeted cancer drugs on the market. There's now over 100 targeted cancer drugs on the market, which, in many cases, have meaningfully improved Overall survival and quality of life.
Sydney Lupkin
Though I should add that gleevec was also considered Incredibly expensive When it launched at $26,000 a year. And that meant even more money Back in the early 2000s. Yeah, the drug is now generic and much cheaper.
Emily Kwong
So gleevec is still being used today?
Sydney Lupkin
Yep, it's still used. Brian still prescribes gleevec and the second, third, and fourth generation drugs that came after. And he's still able to tell patients that they'll be able to live a normal life. He told me about one patient who had leukemia as a child and started taking gleevec. Eventually, she was able to come off the drug with no recurrence of her cancer. And she now has two kids.
Brian Drucker
Her parents thought that she would never live long enough to graduate from high school. And here she is with us today.
Sydney Lupkin
And the researchers kept studying gleevec, and they found out it actually works for other cancers. For example, it can also treat A certain kind of gastrointestinal tumor by shutting off its out of control growth. Dr. Drucker, Brian remembers that he had this one patient who had one of these tumors that he said Made his stomach look like he was nine months pregnant. And he was uncomfortable. He couldn't roll over in bed. He was miserable. And within days of starting gleevec, Brian got a call. The patient was on the other end of the line. And he said he felt so great that he was playing a round of
Emily Kwong
golf, because gleevec was able to, like, turn off the cell growth.
Insa Gothman
Uh huh.
Brian Drucker
Wow.
Emily Kwong
Sydney, in marking the anniversary of Gleevec this week, where is everyone at now? All the people who helped make this possible, like that Swiss biostatistician, Insa.
Sydney Lupkin
She stayed at Novartis and became the executive director in biostatistics. And she's about to retire.
Emily Kwong
And what about Mel the dad?
Sydney Lupkin
Mel the dad? Given three years to live in 1995. He's now 69 years old.
Emily Kwong
Wow.
Sydney Lupkin
Yeah. He got to watch his daughter grow up. He even went back to school and got a second bachelor's degree. And he wants to run the Boston Marathon next. Heck, yeah.
Mel Mann
I'm just thankful for the physicians who I know had to burn a lot of midnight oil to make it happen, and the researchers and people who were involved in the whole process, the people at the sites, the people who crunched the numbers, and just so many people that I have to be thankful for. So it means a lot. I got a second chance at life.
Emily Kwong
Yeah. And what about Brian Drucker, the oncologist who really is responsible for a lot of this and figured out Gleevec?
Sydney Lupkin
Yeah, he developed it. He's gotten to watch people given a death sentence actually go on to live normal lives. And some of them celebrated Gleevec's anniversary with him this past weekend.
Brian Drucker
It is a remarkable and magic moment of reflection because some of the patients on that phase one first in human trial are still with me. And they've seen weddings, births, graduations, grandchildren, all the things that they never thought that they could imagine would happen.
Emily Kwong
