AN UPDATE FROM LIFE
ISSUES INSTITUTE
Great Opportunity to Refute Myths about
the Non-Abortion Uses of RU 486
An Update
U.S. marketing of the dangerous RU 486/Cytotec prostaglandin
(RU 486/PG) abortion technique continues to be stalled over
the lack of a manufacturer, according to the latest public
statement from the organization that controls the U.S. patent.
The June 1997 status report on the Internet website of the
Population Council states that all of the appropriate documentation
has been filed with the U.S. Food and Drug Administration
(FDA), but "additional information on manufacturing still
has to be provided before the drug can be approved."
On May 9, 1997, the Council filed a breach of contract lawsuit
against a Hungarian drug company that backed out of a deal
to provide bulk quantities of RU 486, and that dispute has
apparently not been resolved. The Pro-Life/Pro-Family boycott
of the Hoechst Marion Roussel drug company is still underway
because the company bears great responsibility for the testing
and approval of RU 486 for abortion in the U.S.
Meanwhile, U.S. tests continue on two other chemical abortion
techniques. One test, under the auspices of Abortion Rights
Mobilization (ARM), utilizes a "Chinese clone" of
RU 486 plus Cytotec prostaglandin. The other experiment being
conducted by Planned Parenthood affiliates uses the anti-cancer
drug methotrexate plus Cytotec prostaglandin. (See the July
1997 RU 486 Report for details.)
Seizing an Opportunity
This lull in the pro-abortion supporters push to market
RU 486 offers Pro-Life and Pro-Family advocates an outstanding
opportunity to do some public relations efforts of their own.
In the past five years, we have heard virtually nothing about
the non-abortifacient uses of RU 486. Yet, because of the
hype created in the late 1980s and early 1990s and slavishly
accepted by reporters, news accounts still act as if there
are proven uses outside abortion for RU 486. In truth, such
claims were not borne out then or later. In many cases, they
have been disproved. At the very least, such purported uses
remain unsubstantiated.
Such allegations were always intended to provide cover for
abortion. So, too, were charges that pro-lifers in general,
and the Bush Administration in particular, did everything
they could to stop research into non-abortifacient uses. The
attack focused on the Bush Administrations wise decision
to not allow RU 486 in for personal use.
This edition will provide the reader with information to
address two major items that still come up:
a. A brief overview of the media events that proponents engineered
(1) to plant the seed that there were non-abortion uses and
(2) to portray pro-lifers as attempting to stop research into
those areas.
b. An overview of the research to date demonstrating that
there is no evidence RU 486 can be used, for example to cure
breast cancer, or any other disease.
The Crucial Period, 1989-1992
In retrospect, its clear that the crucial period for
the development of the "accepted knowledge" about
the non-abortion claims for RU 486 was 1989 through 1992.
After the drug was licensed for abortion in France in late
1988, U.S. abortion advocates became increasingly frustrated
and upset. The European companies controlling RU 486 refused
to license or even test it here for abortion. Moreover, the
pro-life Bush Administration was unwilling to either put pressure
on the companies or cut corners on drug approval, and on June
6, 1989 the U.S. Food and Drug Administration (FDA) issued
an "Import Alert" formally banning importation of
RU 486 by individuals for personal use for abortion on safety
grounds.
The RU 486 supporters tried an indirect approach to bringing
RU 486 into the U.S. for abortion. Adeptly using their access
to opinion leaders, control of Congress and scientific associations,
and cooperation from the media, abortion advocates attempted
to build public support for importation by claiming that RU
486 was a "potential" cure for diseases or conditions
affecting millions of Americans, such as breast cancer and
endometriosis. Virtually in the same breath, the RU 486 supporters
tried to discredit Pro-Life and Pro-Family organizations and
the Bush Administration by claiming that they had blocked
U.S. research on these beneficial uses. The FDA issued the
Import Alert in response to political pressure from pro-life
Congressmen and had been responsible for discouraging the
Europeans from conducting any research, abortion supporters
asserted. One of the medias most important but unspoken
assumptions has been that the pro-RU 486 forces have
scientific credibility while the anti-RU-486 forces
have none.
Since 1992, these Trojan Horse claims have remained basically
unchallenged because the focus of the controversy has been
on using RU 486 for abortion. Now in 1997 five more years
of medical data provides even stronger evidence to refute
the myths.
Talking Points Against RU 486
In order to counter these claims, Pro-Life and Pro-Family
advocates should use the following three general themes.
First, the "conventional wisdom" that RU
486 is useful to cure many conditions and diseases is either
completely wrong, grossly exaggerated, or unproven.
In public debates, rather than rebutting each one of the
claims individually, one of the best techniques is to list
them collectively. Soon the list becomes ridiculously long
since no drug could ever cure everything from AIDS to hypertension,
and even arrest aging!
Since RU 486 was first discovered in 1980, researchers have
conducted dozens of test-tube and clinical experiments on
a wide variety of diseases or conditions. Those experiments
have not uncovered any miraculous curative properties for
this powerful synthetic steroid. U.S. marketing of RU 486
for anything except abortion is still years away and will
require much more extensive animal and human testing. In short,
the "potential" uses of a decade ago remain largely
unsubstantiated, unproven, or completely false.
The most noteworthy claim made by RU 486 advocates that RU
486 was a potential cure for breast cancer. Three clinical
trials conducted on women with breast cancer have proven authoritatively
that RU 486 is not a cure for breast cancer.
Moreover, if there had been some validity to the claims made
since the mid-1980s that RU 486 cured breast cancer, why didnt
the manufacturer put enormous effort into research and marketing
such a potentially profitable drug? The obvious reason is
the company recognized early on that RU 486 was not a cure.
In fact, the U.S. National Cancer Institute said so publicly
five years ago during a controversy over its refusal to fund
tests in this county.
And finally, if RU 486 is supposed to be so valuable for
non-abortion purposes, then why would the manufacturer give
away the patent? Acting on instructions from its German parent
company, the French owner of the patent "donated"
the U.S. rights to the Population Council in 1994, and then
gave the rest of the world-wide patent rights to a new start-up
company in April 1997. The obvious answer is that RU 486 was
too much trouble for them as an abortion drug, and they did
not believe that it would be profitable for any other use
in the foreseeable future.
A second major theme is the strong evidence that Pro-Life
and Pro-Family advocates did not and could not block U.S.
research on the non-abortion uses.
In fact, during the late 1980s and early 1990s, the non-abortion
uses of RU 486 were not a research priority because both scientists
and the company controlling RU 486 realized that it had limited
potential and they had more promising projects to pursue.
The lack of progress since 1992 using RU 486 for non-abortion
purposes documented below verifies their judgment.
The strongest evidence supporting the validity of the FDAs
decision in 1989 to issue the Import Alert to protect the
health and lives of women comes ironically from the Clinton
Administration, which has politicized the drug approval process
in favor of RU 486. On President Clintons first full
day in office, he ordered the FDA to reevaluate the scientific
basis for the Import Alert. Nothing was heard for over a year.
On May 14, 1994, at a congressional hearing about the licensing
of the RU 486 patent for abortion, FDA Commissioner Dr. David
Kessler stated that the Import Alert would remain in effect
to protect the health and lives of American women. This startling
admission that the Bush Administration had been right all
along received no press coverage.
Moreover, as a practical matter, since most drug testing
in this country is confidential and done by private companies
and organizations, there was no way for the opponents of RU
486 to prevent research. For example, testing of RU 486 for
abortion at the University of Southern California in Los Angeles
in the 1980s was entirely secret until the researchers published
their findings several years later.
The third theme is that the events of the past five
years show that abortion advocates misrepresented and manipulated
the scientific facts for political purposes. After a three-year-long
campaign trumpeting the alleged importance of non-abortion
uses for RU 486, they precipitously dropped the issue when
Clinton took office. Better public understanding of the RU
486 advocates cynical strategy might undermine their
credibility in the present debates.
Lets review the origins of "conventional wisdom"
and then compare the claims with the latest medical evidence.
Establishing The Claims, 1985 - 1993
1985
The initial media accounts naturally had focused on its novelty
as a method of chemical abortion and its potential to transform
how abortions would be performed. RU 486 blocks the action
of the natural hormone progesterone, which is vital to maintaining
the nutrient lining of the uterus during pregnancy. When RU
486 blocks the action of progesterone, the lining disintegrates,
which starves the unborn baby to death.
However, scientists also had legitimate reason to be interested
in RU 486's theoretical properties as an unique anti-hormone
for a variety of applications beyond abortion. In addition
to being an antiprogesterone (or anti-progestin), RU 486 was
the first antiglucocorticoid to become available for clinical
testing. The American Medical Associations Encyclopedia
of Medicine states that glucocorticoids are hormones produced
by the adrenal glands that "affect carbohydrate metabolism
by increasing blood sugar level and the amount of glycogen
in the liver." According to Dr. L. Michael Kettel writing
in the December 1995 Clinical Obstetrics and Gynecology,
RU 486 is a much less potent antiglucocorticoid than it is
an antiprogestin.
While media accounts have seldom explained or differentiated
between these two properties, most of the research has focused
on RU 486 as an anti-progesterone (or anti-progestin).
The first extensive claims by RU 486 advocates that the drug
had beneficial medical uses surfaced in late 1985 during the
initial big burst of media attention. The occasion was the
publication of a book summarizing the results of the research
on RU 486 up to that time. The co-editor of the book and chief
media spokesman for the pro-RU 486 campaign from 1985 through
1990 was Dr. Étienne É. Baulieu, the key consultant to the
French manufacturer of RU 486, Roussel Uclaf. In Baulieus
chapter in the book, he asserted thatin addition to
abortionRU 486 would be tested for "advanced breast
cancers," "brain tumors," "extra-uterine
[ectopic] pregnancies," and Cushings Syndrome (a
disorder of the adrenal gland).
1989
After the French government licensed RU 486 for abortion
in December 1988, U.S. abortion advocates immediately stepped
up their campaign to market it here. Behind the scenes, the
largest pro-abortion lobbying organizations formed a key "working
group" named the Reproductive Health Technologies Project
(RHTP) to coordinate strategy. Using foundation grants, RHTP
spearheaded the media campaign. Many of the projects mentioned
below required months of preparation before they were ready
to go public.
A video named "Abortion for Survival" released
in April 1989, by the radical pro-abortion organization, Fund
for a Feminist Majority, escalated the list of potential benefits.
It asserted that the drug had "potential" use for
"labor at term delivery, treatment of ulcers, endometriosis,
prostate cancer, and breast cancer." The narrator then
claimed that "pressure from anti-abortion forces threatens
the research and use of RU 486 in this country, and internationally."
The video was aired on Ted Turners TBS cable network
without any time for rebuttal.
In the fall of 1989, heavier promotion started when Baulieu
repeated the claims in articles appearing in two prestigious
U.S. scientific journals, which received national publicity.
1990
The tempo of the public campaign escalated dramatically in
1990. In January and February, Planned Parenthood, the nations
largest provider and promoter of abortion, sponsored a nationwide
series of press conferences, headlining Dr. Baulieu. The media
gave them front-page coverage. On June 26th, the House of
Delegates, the policy-making body of the American Medical
Association, endorsed a resolution supporting more research
and possible use of RU 486. This vote by the nations
largest organization of physicians also generated widespread
media coverage.
The abortion proponents political strategy behind the
frequent mention of the beneficial "other" uses
became public during a July 11, 1990, news conference by Joanne
Howes in New York City. Howes served as director of the Reproductive
Health Technologies Project, an organization identified in
the July 12 Newsday as "spearheading the drive"
to bring RU 486 into the U.S. "By targeting the [U.S.]medical
community, Congress, womens groups and the media, proponents
of the [abortion] pill say they hope to pressure the pharmaceutical
industry and the Bush administration to test and license the
drug," reported Newsday. The story explained that
the "key to their success, Howes said, may be to stress
other possible medical benefits of RU 486, such as in treatment
for breast cancer, and to cast the issue in freedom
of research terms."
Just over a month later, a two-page article cataloging a
sweeping list of non-abortion uses for RU 486 appeared in
the August 22/29, 1990 issue of the influential Journal
of the American Medical Association (JAMA) written
by cancer researcher Dr. William Regelson and two others.
The article claimed that RU 486 has "potential"
to cure patients with advanced breast disease, inoperable
meningiomas, Cushings disease, hypertension, a broad
range of tumors, viral infections, and even AIDS.
On November 19, 1990, then-U.S. Representative (now Senator)
Ron Wyden (D-Oregon) held a Congressional hearing stacked
almost entirely with RU 486 advocates promoting its "beneficial"
uses. In his opening statement, the pro-abortion Wyden attacked
the FDAs Import Alert and claimed that "Many scientists
now believe that the drug can successfully treat debilitating
and life-threatening illnesses such as breast cancer, brain
cancer, diabetes, and Cushings Syndrome." The event
generated extensive national media coverage, including two
stories in the New York Times.
At the hearing covered by the national media, a parade of
witness and former patients who had used RU 486 asserted that
"recent studies have shown" that the drug "is
a promising treatment of a variety of medical disorders,"
including infertility and hypertension, reported the November
20 Philadelphia Inquirer. Dr. Regelson repeated his
assertion from his JAMA article that RU 486 "has
possible value in the treatment of AIDS" and the prevention
of aging.
The lone dissenting voice against these unsubstantiated claims
came from an unlikely source: the representative of the American
Medical Association (AMA), which had adopted a pro-research
policy on RU 486 the previous June. Dr. P. John Seward, an
AMA trustee, asserted that the "published conjecture"
that RU 486 may be an effective treatment for a variety of
illnesses was not based on "any substantiated tests of
the drug."
As for the allegations that the Bush Administration was impeding
research, the federal government has "placed no barriers
in the way of research," asserted a senior official of
the U.S. Food and Drug Administration at the hearing. Associate
Commissioner for Regulatory Affairs Ronald Chesemore explained
that the agency had issued a formal policy called an "Import
Alert" prohibiting importation of RU 486 for personal
use, a position supported by the AMA, for good reason: protecting
women from unsupervised use of a unproven and potentially
dangerous drug. Scientists could obtain RU 486 for testing
by following appropriate procedures, he asserted.
During 1991 and 1992, Wyden continued to badger the FDA about
the "lack of research" because of the Import Alert.
1991
In February, 1991, pro-RU 486 speakers at two workshops at
the annual meeting of the nations largest scientific
society, the American Association for the Advancement of Science
(AAAS), promoted its supposed non-abortion uses. One speaker
received nationwide press coverage by claiming that RU 486
and similar drugs have been shown to slow or stop the growth
of some kinds of breast tumors. Later in the meeting a committee
of the organization passed a resolution calling for more research.
The headline of an article about the meeting in a leading
scientific magazine was typical of the type of coverage that
announcements such as this received: "RU-486: Abortion
Controversy in U.S. Clouds Future of Promising Drug - Progesterone
antagonist developed in France and used to terminate pregnancy
is potential anticancer and anti-Cushings agent, but
efforts by antiabortion forces have impeded research on it
in the U.S."
Meanwhile, a new facet of the pro-RU 486 campaign kicked
off when an abortion supporter introduced a resolution into
the New Hampshire state legislature. This resolution, which
was subsequently used throughout the country in virtually
the same wording, inaccurately claimed that RU 486 had "shown
considerable efficacy in treating certain kinds of breast
cancers and brain tumors, Cushings syndrome, and other
diseases." The resolution, which was passed on May 12,
1991, called for introduction of RU 486 "for its significant
medical value" and offered New Hampshire as a clinical
test site. These assertions depended on the "big lie"
technique, and proponents counted on busy legislators not
having the time to research the true picture.
Over the following year and a half, the pro-RU 486 campaign
received enormous media coverage as state legislatures all
over the country debatedand sometimes passedsimilar
measures. The states where the resolutions were introduced
included Arkansas, California, Florida, Hawaii, Illinois,
Kansas, Maine, Minnesota, New Jersey, New York, and Wisconsin.
In July 1991, one of the nations most prestigious scientific
agencies jumped into the RU 486 controversy on the side of
the abortion advocates. The Institute of Medicine of National
Academy of Sciences released a book-length study titled Biomedical
Politics. One chapter devoted to "A Political History
of RU 486" described the important developments and insisted
that "politics " rather than "medical merit"
was preventing introduction. RU 486 had "many promising
applications, dilating the cervix, to help avoid cesarean
sections; treating certain breast cancers that grow in response
to sex hormones; treating endometriosis, the third leading
cause of infertility in the United States; and controlling
Cushings syndrome," claimed the author R. Alta
Charo.
On December 5, 1991, then-Representative Wyden held another
congressional hearing timed to provide a lead-in for a two-day
national strategy meeting of leading RU 486 supporters. The
principal theme running throughout the testimony of top RU
486 researchers was the claim that all of the scientific evidence
was in favor of RU 486. Abortion "politics" (i.e.
Pro-Life and Pro-Family resistance to abortion) was keeping
it out of the U.S., they insisted. Once again, the hearing
generated more pro-RU 486 publicity. (For example, the headline
in a New York Times editorial on December 26, 1991
was "Fight Cancer, Not RU-486.")
The two-day conference held across the Potomac from Washington,
D.C., brought together RU 486 activists from Europe and this
country both to discuss the status of research and to plot
their campaign. One of the top U.S. abortion supporters revealed
publicly for the first time just how vital promoting the "other
beneficial uses of RU 486" was to their campaign. Kate
Michelman, head of the National Abortion and Reproductive
Rights and Action League (NARAL), disclosed that public-opinion
polling from the previous March indicated that "informing
people that RU 486 can have other possible medical uses significantly
increases the belief that the drug must be introduced into
this country." She noted that "Perhaps the most
powerful argument that we found for testing and licensing
of RU 486 is its possible use for treating other diseases."
In other words, the best way to get RU 486 into the country
for abortion is to stress how it could cure non-abortion-related
medical conditions.
1992
In January, 1992, Dr. Baulieu generated media coverage over
the release of his book about the "abortion pill."
On January 22, leaders of the largest pro-abortion organizations
took the occasion of the anniversary of Roe v. Wade to announce
intensification of their campaign to bring RU 486 into the
U.S. During the ensuing months, RU 486 advocates continued
to receive a lot of press coverage about the state legislative
resolutions demanding "freedom of research." And
in March at the annual meeting of the American College of
Physicians in San Diego, a group of California physicians
announced the formation of a new organization, Physicians
for RU 486. Their leader told the press that their aim was
to encourage the European companies to supply RU 486 "for
all appropriate research."
On July 28, 1992, just a few months prior to the presidential
election, Wyden held his third congressional hearing to investigate
the status of medical research on RU 486. In his opening statement,
Wyden criticized the federal government for allegedly blocking
testing for RU 486 and especially expressed his outrage that
RU 486 was not being testing for breast cancer in this country.
The opening witness, actress Cybil Shepherd, attracted unusually
large media attention. Like all but one of the other witnesses,
she urged testing of RU 486 for non-abortion uses. "Shepherd
said the drug can help cure brain tumors, endometriosis and
depression, as well as breast, ovarian and prostate cancer,"
reported the July 29 San Francisco Chronicle.
Representing the National Right to Life Committee, I testified
that "no one, including pro-lifers, opposes research
on the non-abortion-related uses of RU 486." I also rebutted
the previous witnesses claims by stating that "There
is no scientific evidence showing that RU 486 has any proven
use except abortion."
Wyden followed up the hearing with an August 10 letter to
the key agency for cancer research, the U.S. National Cancer
Institute (NCI), to express his distress that the agency had
turned down an opportunity to test RU 486 for breast cancer.
Wyden was disturbed by NCIs "failure to pursue
much-needed research on an important new drug for a disease
that claims tens of thousands of American lives each year."
The Congressman noted that the research project had gone to
Canadian researchers instead, (discussed in detail below).
The agencys reply to Wyden was highly instructive.
In a 6˝-page, single-spaced letter, Dr. Bruce Chabner, director
of NCIs Division of Cancer Treatment, reassured Wyden
that scientificnot politicalconsiderations had
governed NCIs decision not to pursue RU 486 research.
In support of this contention, Chabner made the following
points, which in large measure are just as valid now as they
were five years ago:
"Clinical trials of RU-486 in human breast
cancer are very limited."
"At this point, there is little preclinical
or clinical data to suggest that RU-486 will offer any advantage
over other currently available hormone therapies."
"RU-486 is not novel, has not demonstrated
a potential for cure, and at this time offers, at best,
the possibility of only modest, transient benefit to a fraction
of the women with advanced breast cancer."
"In short, RU-486 did not, and does not now,
appear to have the potential to improve significantly on
available hormone therapy for breast cancer. This decision
was based solely on the scientific judgment of NCI staff."
Unfortunately, amid the hubbub of the presidential campaign,
the media did not pick up on this authoritative and direct
refutation of claims that RU 486 could cure breast cancer.
Since 1992
Only one major report on the beneficial uses of RU 486 has
appeared since Clinton took office. Obviously planned months
in advance, the Institute of Medicine (IOM) of the National
Academy of Sciences convened a by-invitation-only conference
in April 1993, to discuss the clinical applications of RU
486. The attendees were a virtual "whos who"
of abortion advocacy organizations representatives,
and naturally the book published later in the year, titled
Clinical Applications of Mifepristone (RU 486) and Other
Antiprogestins, reflected their point of view which recycled
previous claims based on fragmentary and inconclusive research.
Even Leslie Z. Benet, Ph.D., the chairman of the IOM committee
that wrote the book, admitted in the September 9, 1993 Philadelphia
Inquirer that "in breast cancer and other areas,
the research is very spotty."
During the five-year period since President Clintons
election, the abortion advocates strategy has been markedly
different from the three-year period just preceding it. Once
they took over key federal posts in 1993, they changed from
an "outside" to an "inside" political
strategyfrom promoting the "potential" non-abortion
uses of RU 486 to praising the safety, effectiveness and ease
of RU 486/PG abortionand from creating a steady stream
of media events to publicizing just major developments.
Unfortunately, although the rhetoric about "other uses"
toned down considerably after January 1993, the damage had
been done. Through constant uncritical repetition by the media,
very preliminary research findings on cells in test tubes
became exaggerated into firm projections that RU 486 was a
miracle drug. Those claims became the conventional wisdom,
which is still currently used by the media and RU 486 proponents.
For example, a fact sheet dated June 1997 on the Internet
website of the Population Council, which controls the patent
and is seeking licensing, made the following assertion that
summarizes many of the claims that have been made:
"Mifepristone [RU 486] is believed to have the potential
for use in treating a wide range of conditions related
to pregnancy (induction of labor and cervical ripening),
gynecological disorders (infertility, endometriosis and
uterine fibroids), and other medical problems (Cushings
disease [probably means Cushings syndrome], meningioma
[non-malignant brain tumor], and breast cancer."
Current Status of Non-Abortion Uses of RU 486
In contrast with the sweeping claims by the Population Council,
the following section describes the status of each non-abortion
use in alphabetical order using sources either favorable to
or neutral on using RU 486 for abortion..
In general , the "potential" uses of a decade ago
still remain largely unsubstantiated, unproven, or completely
false. The information compiled below reveals that RU 486
is currently only licensed in the world for two uses: (1)
abortion in France, the United Kingdom, Sweden, and the Peoples
Republic of China, and (2) expulsion of a dead unborn baby
(only in France).
This status report utilizes the six sources that are cited
in brief with each item and listed in detail at the end of
the article.
AIDS
"The use of RU 486 (or analogues) has been suggested
in premenstrual syndrome, postmenopausal flushes, Alzheimers
disease, and AIDS, but there is currently no firm scientific
background to justify trials (emphasis added)." (Baulieu,
1993, p. 105)
Abnormal uterine bleeding
"No clinical experience in this venue has been published."
(Morales et al. 1996, 458)
Breast Cancer
As described in detail above, from 1989 through 1992 RU 486
advocates heavily promoted RU 486 as a possible cure for breast
cancer, and the media picked it up uncritically.
Yet, as recounted above, in 1992 the NCI stated quite clearly
that RU 486 was not a cure for breast cancer. Ironically,
that conviction was affirmed by the final report of the clinical
trial in Canada that Congressman Wyden was so upset did not
get conducted in the U.S.
In October 1996, a team of researchers headed by Daniele
Perrault published an article "Phase II Study of the
Progesterone Antagonist Mifepristone in Patients With Untreated
Metastatic Breast Carcinoma: A National Cancer Institute of
Canada Clinical Trials Group Study" in the Journal
of Clinical Oncology (vol. 14, no. 10, pp. 2709-2712).
Note that the study was under the auspices of the NCI of Canada.
This article recounted the results of the two previous clinical
trials on 11 women in the Netherlands and 22 women in France.
It noted that evaluation of the results was "made difficult"
by the inclusion of women who had failed prior therapy. In
the Canadian trial "of recurrent breast cancer patients,
mifepristone produced only three partial responses in 28 patients."
This 11% response rate was comparable to the previous two
European studies where the response rates were 9% and 13.6%.
In conclusion, the authors stated quite categorically that
"We do not feel that mifepristone should be pursued
as a single-agent therapy for breast cancer" (p.
2711). They suggested testing RU 486 in conjunction with other
drugs, but cautioned that "before embarking on such combination
trials, more complete laboratory information should be obtained
on the nature of the interaction and the optimal scheduling
of the two agents."
Cushings Syndrome
After describing the results of three case reports and one
research study on a total of 21 people, the authors state
that "Exploration of mifepristone in the treatment of
Cushings syndrome is in its infancy. The cases reviewed
in this report comprise the entire medical literature."
(Sartor and Cutler, 1996, p. 509)
Ectopic pregnancy
"There is only one study reporting on the use of RU
486 (200 mg day for 4 days) in women with laparoscopically
confirmed ectopic pregnancy. . . .The role of antiprogestin
in the medical therapy of ectopic pregnancy remains to be
clearly defined. Certainly, the timing, dosing, and efficacy
of RU 486 treatment in this scenario awaits future studies."
(Morales et al 1996, p. 458)
Endometriosis
Although pilot studies indicate that RU 486 "may prove
useful of endometriosis and uterine leimyomatas, larger trials
are necessary to confirm its efficacy." (Ulmann et al.
1995, p. 257)
"The efficacy of RU 486 in endometriosis awaits a randomized
clinical trial." (Morales et al. 1996, p. 455)
Glioma (malignant tumor of
the central nervous system)
"No studies of mifepristone have been reported in clinical
trials with glioma patients." (Sartor and Figg, 1996,
503)
Intrauterine fetal death
Tests show that RU 486 alone is able to induce labor in women
with intrauterine fetal death and the expulsion "takes
place significantly earlier than in patients given a placebo."
RU 486 is approved for that purpose in France. (Ulmann, et
al. 1995, p. 253)
Labor induction
The authors cite the results of one study and state that
"dose-finding studies are currently in progress to determine
the minimal dose." (Ulmann et al. 1995, p. 256)
"Much more work into efficacy, secondary benefits, and
safety as well as cost comparisons of various regimens using
mifepristone would be beneficial and are necessary before
any clinical use should be considered at this time."
(Edwards, 1996, p. 472)
Meningioma (rare non-malignant, benign brain tumor)
"At this time, there are no reports of controlled trials
of mifepristone in the treatment of patients with meningiomas."
(Sartor and Figg, 1996, p.503)
Premenstrual syndrome (PMS)
"There have been two clinical studies of RU 486 treatment
of PMS. . . .Studies to date suggest that RU 486 in large
doses or administered only during the luteal phase is not
a valid therapeutic intervention for women with PMS."
(Morales et al, 1996, 457-458)
Prostate cancer
"No studies of mifepristone have been reported in patients
with prostate cancer."
(Sartor and Figg, 1996, p. 504)
Uterine leiomyomatas (benign pelvic tumors, also known
as fibroids)
Although pilot studies indicated that RU 486 "may prove
useful for treatment of endometriosis and uterine leimyomatas,
larger trials are necessary to confirm its efficacy."
(Ulmann et al. 1995, p. 257)
"The mechanism of action of RU 486 in reduction of leiomyomata
growth remains to be fully elucidated." (Morales et al.
1996, p. 457)
Conclusion
From 1989 through 1992, Pro-Family and Pro-Life advocates
pointed out that the RU 486 advocates claims about these
non-abortion uses were either widely exaggerated or just plain
wrong and that research was not being held up, but the media
generally ignored us.
Unfortunately, during the past five years,. these unsubstantiated
claims have gained the status of "common knowledge"
or "accepted wisdom," and they continue to surface.
They need to be refuted, and the current lull in the news
about RU 486 offers an excellent opportunity.
The public needs to know that despite over a decade and a
half of research, the primary (and almost exclusive) use for
RU 486 is abortion. RU 486 is not a "miracle" drug
and is years away from marketing in the U.S. for any purpose
except abortion. For example, it is not a cure for breast
cancer.
Also Pro-Life and Pro-Family organizations and the Bush Administration
have had a "bum rap" about blocking research. From
the beginning, the organizations categorically denied opposing
testing of RU 486 for non-abortion purposes and pointed out
that RU 486 research was not being pushed because the drugs
owner realized that the results would not be worth investing
the time or money.
And finally, the public needs to know that the abortion advocates
cynically distorted the scientific facts about the non-abortion
purposes of RU 486 to gain support for their campaign to import
the drug for abortion.
