Debate on " Whether clinical trials in developing countries are expolitative?"

  1. 1. Whether Clinical Trials In Developing Countries Are Exploitative ?
  2. 2. Clinical trial
  3. 3. Developing countries World Economic Outlook Database April 2015 -- WEO Groups and Aggregates Information [Internet]. [cited 2016 May 29]. Available from: http://www.imf.org/external/pubs/ft/weo/2015/01/weodata/groups.htm

  6. 6. Marxist approach to exploitation “An individual labor more than is strictly necessary to meet his or her own needs and hence more than would strictly be required to sustain his or her labor over time . When the product of this surplus labor is appropriated by another person, we have exploitation” - Jon Elster (Political scientist) Jon Elster. (1986). An Introduction to Karl Marx. [Online]. Cambridge: Cambridge University Press. Available from: Cambridge Books Online <http://dx.doi.org/10.1017/CBO9781139163620.
  7. 7. Contemporary Non-Marxist Approaches to exploitation  Diffuse, unclear ethical concept A B Takes advantage in an inappropriate way
  8. 8.  A’s proposal is forceful only A proposes to violate B’s rights if B rejects the proposal  It is just that a rational person would choose participation in a trial over no medical care
  9. 9.  All participants are receive care that is at least as good as and probably better than if the trial had not been conducted at all  Those who receive placebo also is not worse than normal care  There are scientific , social and economic reasons to prefer a PCT to an ACT  If B is having an illness which works 50% of the time, we won’t object A from providing it  why we find it wrong as participants can expect to benefit 50% of the time.
  10. 10. Research treatment  “Although I am a doctor , you are not my patient. I am conducting a trial. If you are selected to receive Surfaxin, then you will receive care that we think will prove beneficial. If you are selected to receive placebo, then your baby will not receive such care. If you don’t want to participate with us on those terms, that’s fine. But I don’t want you to think that I regard your baby as my patient”  Why physician patient relationships is automatically applied to relations between researchers and subjects even if the researchers happen to be trained physicians
  11. 11. Exploitation is not limited to clinical research in developing countries, but in all clinical research All research “uses” the participants to gain information
  12. 12. Case studies
  13. 13. A • Standard of care • Ethics of study design B • Informed consent C • Reasonable availability • Fair compensation
  14. 14. The Havrix Trial (1990)  Kingdom of Thailand  Population 56.58 million (1990)  GDP per capita - US$1508  Health expenditure per capita of GDP 4%  Health expenditure per capita $109 (1995)  Life expectancy at birth 70(M) 73 (F)  IMR – 20.5 per 1000 live births  Physicians per 100000 – 30  Place – Kamphaeng Phet , Northern Thailand
  15. 15.  Randomized double blind phase 3 trial of Hepatitis A with Hepatitis B vaccine as control in 40’000 children aged one to six.  Walter Reed Army Institute of Research , USA  SmithKline Beecham Biologicals  Thailand Ministry of public health  Incidence – 119 per 100000 population  Prior JE vaccine study  No prior agreement to make Havrix available in Thailand
  16. 16. Benefits  40,000 children in trial received Hepatitis B and A vaccines  Augmented medical services  Community public health workers for care  New refrigerators in Public health stations
  17. 17.  Inspection of schools and identification of deficiencies in toilet facilities , hand washing facilities and water storage  Unlimited stocks of disposable syringes and needles and training to reduce incidence of blood borne diseases  Training of Thai researchers  Experience in conducting further research  13 senior physicians and US ministry officials to monitor the safety and efficacy of the trial
  18. 18. The Zidovudine trial (1994)  A study to discover effective approach to maternal fetal HIV transmission in developing countries , African countries  WHO meeting  RCT for shorter and simpler regimen of AZT vs. placebo  16 trials in 11 countries , out of which 15 was placebo controlled ( of which 9 funded by NIH and CDC)
  19. 19. International Ethical Guidelines For Biomedical Research Involving Human Subjects (1993)  “ As a rule, the sponsoring agency should agree in advance of the research that any product developed through such research will be made available to the inhabitants of the host community at the completion of successful testing. Exceptions to this general requirement should be justified and agreed to by all concerned parties before the research begins”
  20. 20. Reasonable availability is vague  No definition of community ?  Whether to deliver the drugs to all sick person in the community ?  How long ? For drugs which need to be taken for life time?  What if the host country is not able to handle the cost anytime in the near future?
  21. 21.  No single trials ever proves or disproves the effectiveness of an intervention  Guaranteeing access after only one trial is unrealistic  Why responsibility for supplying benefits should rest with the sponsor ?  NIH /CDC – which are committed to focus on research and not health care implementation.
  22. 22. The Surfaxin trial (2000)  Plurinational State of Bolivia  Population 8.86 million (2005)  GDP per capita - $2700  Health expenditure per capita : $179  Life expectancy at birth 63 (M) and 68 (F)  IMR – 53 per 1000 live births  Physicians per 100000 population :73  Sponsor – Discovery labs, USA
  23. 23.  Randomized double blind placebo controlled phase 3 trial of Surfaxin for the treatment of RDS in 650 premature infants  Hospitals chosen – NO surfactant available for treatment of RDS  Sponsors provided – Endotracheal tubes, ventilators and antibiotics for all study participants  Team of American Neonatologists to supervise the study and training of local health care personal  Ventilator support to placebo is known to improve survival and was better than the treatments available to both groups prior to study  No firm agreement was reached before the start of trial regarding availability
  24. 24.  Steering committee composed of host country members to ensure that appropriate safety standards would be met  No subjects were denied treatment to which they now have access  “the provision of placebo ….to 325 infants in control group….result in preventable deaths of 16 infants”  If not engaged in trials  it would have been more  There are preventable deaths all over the world. If the goal is to reduce their number, it is not clear what strategy will best achieve it …
  25. 25. Principle of reasonable availability  Participants take risks in the trial Why the validity of a potential participant’s consent should be at all related to a decision to make a product available to others in the post trial environment?  Why national boundaries are of moral significance?  If the same trial done by Indian pharmaceutical company ?  It is mistake to assume as the world is divided into very poor and very rich  If PCT seeks to test the efficacy of a drug that could be provided to many patients in a moderately poor nation but would be unaffordable in a very poor nation ?
  26. 26.  So if RA is feasible  it will generate a shift from more affluent persons of the world to less affluent  If RA is not feasible and a precondition of a trial result in no study at all, and results in less distribution.
  27. 27.  Colonial powers plundered natural resources from countries in the past , so it is their duty o provide resources to under developed  Poorest societies of the world are those that have had the least economic contacts with highly industrialized nations  They do have such obligation , but insisting on RA is not the best way to fulfill it Mennis, Bernard. The American Political Science Review 72.2 (1978): 789-90. Web.
  28. 28. Informed Consent  In USA anywhere between 25 – 50% of the subjects do not understand what it is that they have agreed to.  Among 200 patients being treated at the University of Pennsylvania Cancer Center, 40 percent did not know the purpose or nature of the procedure they had undergone and 45 percent could not give even one major risk or cite a possible complication resulting from it.
