Transcript and Presenter's Notes

Title:


1
Is the Developing World the Answer?
  • Unethical clinical trials in the Third World
  • Sammy Almashat, MD, MPH
  • Sidney Wolfe, MD
  • Public Citizens Health Research Group

2
Outline
  • History and structure of human experimentation
  • The commercialization of human experimentation
    conflicts of interest abound
  • A story of self-regulation and the honor code
  • Globalization of clinical trials Is the
    developing world the answer?
  • Case studies of double-standards for the Third
    World and efforts to stop unethical trials

3
Clinical Trials
  • Thousands of trials of pharmaceuticals and
    medical devices conducted on tens of thousands of
    people every year
  • Human testing necessary to ensure safe and
    effective products prior to marketing
  • The question is whos doing the testing on whom,
    and whos watching them?

4
The Birth of a Drug
  • Test tube (in vitro) testing
  • Animal testing
  • Human testing
  • Phase 1
  • Few healthy patients, testing safety
  • Phase 2
  • First study with sick patients, testing safety
    and efficacy
  • Phase 3
  • Largest trials with sick patients, testing safety
    and efficacy

5
Time is Money
  • Drug development is risky, expensive, and
    time-consuming
  • Average drug reaches market 7-10 years after
    first tests at a cost of anywhere from 55
    million to 800 million per drug
  • Incentive is high to cut costs (and corners) and
    speed up the process

6
The Economics of Drug Development
  • Human Experimentation Corporations (HECs)
  • Started in the 1970s as small companies
    specializing in biopharmaceutical (bench) testing
  • Grew dramatically in the past few decades and
    moved into clinical (human) research, growing to
    a 20 billion industry by 2008, with annual
    growth rates of 15-17
  • The IRB industry
  • Paralleled growth of HECs
  • Increasingly for-profit
  • IRB-shopping

Birth of Research Ethics
  • Atrocities of human experimentation in the 20th
    century prompted the development of universal
    ethical principles to govern all such research in
    the future

9
Universal Principles in Human Subjects Research
  • What do we mean by unethical?
  • Nuremburg Code
  • Declaration of Helsinki
  • Belmont Report and Common Rule (U.S.)
  • FDA (abandoned Helsinki in 2008)

10
Universal Principles in Human Subjects Research
  • Informed consent
  • Truly voluntary (not coerced) participation
  • Beneficence
  • Equity and justice

11
Clinical trial oversight
  • U.S./Host Govt. IRBs
  • Drug Company/HECs

2009 GAO goes undercover
  • Fake IRB
  • Fake medical device company with fake device
  • Real medical device and IRB companies and the
    Feds all took the bait

17
Globalization of Clinical Trials
  • 80 of drugs are now approved based on data from
    foreign clinical trials
  • Over half of clinical trial subjects and sites
    are located outside the United States
  • One-third of trial investigators are now from
    foreign sites

18
Why are companies moving abroad?
  • Cost
  • Speed
  • The patient advantage
  • Escaping regulatory burdens

Special considerations with vulnerable populations
  • Exploitation is almost inherent in these trials
  • Lack of informed consent
  • Direct and indirect coercion
  • Lack of Equity
  • Lack of Recourse
  • Companies are not liable for intentional let
    alone unintentional harm caused by experimental
    drugs (certainly not liable for NOT giving
    effective treatment to a placebo group).

23
  • Case Studies
  • Double standards for the Third World

24
Case Study Unethical HIV trials
  • 1997 Nine U.S. government-funded studies of
    pregnant women in Africa, Asia, and the Caribbean
  • Half the women in these trials received AZT, a
    therapy proven to help prevent HIV transmission
    to the fetus
  • The other half received ineffectual placebos

Case Study The Surfaxin trial
  • Title of internal FDA meeting Use of
    placebo-controls in life threatening diseases is
    the developing world the answer?
  • Location Mexico, Peru, Bolivia, Ecuador
  • Design Surfaxin vs. placebo (vs. approved
    surfactant)

32
Case Study The Surfaxin trial
  • Discovery Laboratories (Johnson Johnson),
    Doylestown, PA
  • Synthetic surfactant (Surfaxin)
  • 4 surfactants on the market (1st in 1990)
  • Associated with 34 relative reduction in
    neonatal mortality (Cochrane meta-analysis)Witho
    ut doubt the most thoroughly studied new therapy
    in neonatal care (NEJM review)

33
Case Study The Surfaxin trial
  • Further placebo controlled trials of synthetic
    surfactant are no longer warranted. (Cochrane)
  • FDA Conduct of a placebo controlled surfactant
    trial for premature infants with RDS is
    considered unethical in the USA.
  • European trial Surfaxin vs. approved surfactant

35
Case Study The Surfaxin trial
  • February 2001 Public Citizen writes to HHS
    Secretary Tommy Thompson
  • March 2001 Bolivian health ministry says the
    study is totally prohibited for legal, ethical
    and social reasons
  • April 2001 Discovery announces study changed to
    compare to known effective surfactant

What needs to be done
  • More oversight
  • Addressing conflicts of interest
  • Tying in with more high-profile Third World
    health justice causes (e.g. access to medicines)
