MICHELLE LA MOTHE, MD: Hello. Welcome
to our webcast. I'm Dr. Michelle La Mothe. Recently approved
by the FDA, mifepristone, long known as RU-486, has a long history of development.
It was first developed in France but it has taken 20 years for this drug
to be approved in the United States. Explaining its long journey
from Europe to the United States are two experts. Dr. Richard Hausknecht,
Medical Director of Danco Laboratories, and Associate Clinical Professor
of Obstetrics and Gynecology, Mount Sinai School of Medicine, and Dr. Beverly
Winikoff, Director of Reproductive Health at the Population Council.
Good evening. Thank you for joining us. Dr. Winikoff, can you
tell us a little bit about the beginning of this drug in France more than
20 years ago?
BEVERLY WINIKOFF, MD: The drug started out in the laboratory of
a pharmaceutical company in France and it was originally developed as a
hormone blocking drug and it was soon realized that this meant that it
could be used to block early pregnancy from continuing. So the French
developed this drug as a medical abortifacient, in other words, a drug
women could take to end pregnancies, and after a certain number of years
they discovered that it worked even better if it was used in combination
with another kind of drug, a prostaglandin, which is a drug that makes
smooth muscles contract, which meant that the effectiveness of this drug
was increased from about 70% to well over 90%.
At that point, the French company felt they could market it as a drug
for this purpose. It was approved in France and in the same year
also approved in China, and that was 1988. It went on the market
and became a successful drug in France for abortion. Not too long
after that, in the early 90's, it was also approved in the United Kingdom
and in Sweden. And there it stayed, in France, the United Kingdom,
and Sweden, for almost a decade without going anywhere else.
MICHELLE LA MOTHE, MD: You are with the Population Council and
the Population Council has been involved, I believe, in bringing this drug
to the United States. Can you talk to us a little bit more about
how the Population Council became involved?
BEVERLY WINIKOFF, MD: Sure. The Population Council is a
research organization that had been working on this drug and its uses since
the early 80's under a contract from the French manufacturer and never,
frankly, envisaged being an introducer of this drug in the United States
or anywhere else. But the drug became a political symbol and the
company became unwilling to introduce it into the United States for political
reasons.
MICHELLE LA MOTHE, MD: You mean the French company.
BEVERLY WINIKOFF, MD: Roussel. And that company then was
under enormous pressure to do something with the drug, to make it available
elsewhere, and didn't want to do it itself. So it looked around for
someone else to take over the drug and there wasn't any other commercial
entity willing to do this. So it decided to donate the drug to a
nonprofit entity who could take on the responsibility. The Population
Council had had experience with registration of other drugs, for example
in this case Norplant contraceptive device and also the IUD, so they knew
how to do regulatory work and were willing to take on the responsibility,
and that's how it started.
MICHELLE LA MOTHE, MD: The regulatory work, specifically in the
United States, has to do with the FDA, the entire approval process.
So the Population Council was fairly well-versed in having brought other
drugs through?
BEVERLY WINIKOFF, MD: Relative to any other noncommercial entity,
I would say it was an organization that had a large amount of experience.
Relative to pharmaceutical companies, no. It was a big, big new challenge.
RICHARD HAUSKNECHT, MD: Once they had the patent rights in the
United States to mifepristone, they then had to find somebody who would
produce it, manufacture it and distribute it, and that was an equally daunting
task because there was no particular company that had the capability to
produce it that was interested in any way. They didn't want to get
anywhere near this drug. So what was necessary was the formulation
of a brand new company, and that's exactly what happened. Danco Laboratories
was formed with tremendous help from the Packard Foundation. They
gave a significant amount of money to get the process started. And
then there was a group of investors who came on board and a small company
was formed, Danco Labs, which I joined a little over a year ago.
We, and I say Beverly and I and our gang, went and visited the FDA repeatedly
throughout the summer and, with great help from a wonderful attorney, we
were delighted on the 28th of September to have approval of Mifeprex for
the termination of early pregnancies up through 49 days. It's been
a long, arduous process and a great deal of credit goes to the Population
Council for having stuck with it.
MICHELLE LA MOTHE, MD: Thank you Dr. Hausknecht and thank you
Dr. Winikoff for joining us. And thank you. I'm Dr. Michelle
La Mothe.
