CIOMS GUIDELINES: RELATION TO THE DECLARATION OF HELSINKI Robert J. Levine Professor of Medicine, Lecturer in Pharmacology, Co- Chair: Interdisciplinary Bioethics Program Yale University Santiago, October 15, 2003
HELSINKI LINK • Purpose in 1982: to advise how the principles of Helsinki “could be effectively applied, particularly in developing countries.” • 1982: Minor deviations; e.g., consent through ‘intermediary’.
CIOMS 1993 • Substantial deviations: circumlocutions. • On phase I drug testing: “The requirement…of Article III.2, ‘subjects should be volunteers – either healthy persons or patients for whom the experimental design is not related to the patient’s illness’ is not to be disregarded lightly.”
HELSINKI REQUIRES REVISION* • Illogical [therapeutic vs. nontherapeutic research] • Out of touch with contemporary ethical thinking [placebo controls] [Friday] • Widely disregarded • Loss of authority *Ottawa WMA Ethics Committee
Short Duration AZT Trials 1997 • Criticism in New England Journal of Medicine. • The most acrimonious debate on ethics of clinical trials since 1970s. • Publicity with unanticipated consequences. [Friday] • WMA and CIOMS each launched document revision projects. • A major objective of each organization was ‘harmony’.
CIOMS 2002 • There is more harmony with Helsinki than there was in 1993. • There are no circumlocutions as regards differences with Helsinki. • Differing Guidelines simply stated. • WMA clarifications 2000-2001 failed to secure consensus: [Friday] • Some think it went too far. • Some deplore loss of substantive standard. • Some think it incomprehensible.
THERAPEUTIC AND NONTHERAPEUTIC RESEARCH • II.6 The doctor can combine medical research with professional care…only to the extent that…research is justified by its potential…therapeutic value for the patient. • III.2 The subjects should be volunteers – either healthy persons or patients for whom the experimental design is not related to the patient’s illness.
FORBIDDEN BY ARTICLE II.6 • Pathogenesis • Pathophysiology [eg, catecholamine role in affective disorders] • Epidemiology
THERAPEUTIC RESEARCH • An incoherent concept • All research has some components that are not intended to be therapeutic • Research is defined as the pursuit of generalizeable knowledge
The fallacy of the package deal • Nontherapeutic components are justified as ‘therapeutic’ • Repeated coronary angiograms; endoscopies • Liver biopsies (to maintain double blind) • Placebos administered into the coronary arteries
COMPONENT ANALYSIS • “…interventions or procedures that [do or do not] hold out the prospect of direct benefit for the individual subject.”
BENEFICIAL PROCEDURES • Justification as in medical practice • Risk justified by anticipated benefit • Relation of anticipated benefit to risk is at least as favorable as that of alternatives
RISK JUSTIFICATION • Procedure or intervention: • Beneficial: limited by personal benefit only • Nonbeneficial: limits and thresholds
Minor increase over minimal risk [vulnerable subjects] • Reasonably commensurate with those in actual or expected situation • Anticipated knowledge of vital importance to understanding the subject’s disorder or condition
HELSINKI REVISION 2000 • 28.The physician may combine medical research with medical care, only to the extent that the research is justified by its potential prophylactic, diagnostic or therapeutic value.
HELSINKI STILL REQUIRES REVISION • Illogical [therapeutic vs. nontherapeutic research] • Out of touch with contemporary ethical thinking [placebo controls] • Widely disregarded • Loss of authority
HELSINKI 2000 • Accomplishments • Clarification of language. • Removal of the language of ‘therapeutic’ and ‘nontherapeutic’ research. • Remaining to be done • Clarification of position on placebo controls • Removal of remnants of ‘therapeutic’ and ‘nontherapeutic’ logic.
CIOMS International Ethical Guidelines: 1993 • [Helsinki] does not provide for controlled clinical trials. Rather it assures the freedom of the physician “to use a new diagnostic or therapeutic method if it offers hope of saving life….[T]here are customary and ethically justified exceptions to…Helsinki. A placebo, for example….[further Friday]
HELSINKI HISTORY • Formation of Ethics Committee 1953 • Repudiation of Nuremberg as a document created by jurists to set standards for criminal prosecution • Cites a need for a document by physicians for physicians
DECLARATION OF HELSINKI • Introduction: The WMA Declaration of Geneva binds the physician with the words: “The health of my patient will be my first consideration.” • Section II refers to ‘doctors’ and ‘patients’ • Section III refers to ‘investigators’, ‘subjects’, ‘volunteers’ and ‘individuals’
