Presentation overview
• Definitions-why are we here?
• Why am I giving this talk?
• More on integrity
• A few personal vignettes
WHILE MY FOCUS IS ON HUMAN RESEARCH, THE KEY MESSAGES
APPLY TO ALL MEDICAL RESEARCH
Purpose of medical research
• Prevent, cure, or treat disease and related human conditions
• Make the lives of our patients better
Johns Hopkins is a special place
For me, research on humans necessitates a commitment to help participants access the best
possible care at the same time
I am also their doctor
Definitions: research
…studious inquiry or examination; especially:•investigation or experimentation aimed at the discovery and interpretation of facts, •revision of accepted theories or laws in the light of new facts, or •practical application of such new or revised theories or laws
http://www.merriam-webster.com/dictionary/research?show=0&t=1316277023
Definitions: human subjects research (CFR Title 45; Part 46)
(f) Human subject means a living individual about whom an investigator (whether professional or student) conducting research obtains:
(1) data through intervention or interaction with the individual, or
(2) identifiable private information.

Scientific misconduct
The violation of the standard codes of scholarly conduct and ethical behavior in professional scientific research
http://en.wikipedia.org/wiki/Scientific_misconduct
Research misconductJohns Hopkins Definition
… means fabrication, falsification, or plagiarism in proposing, performing, or reviewing research, or in reporting research results.a) Fabrication is making up data or results and recording or reporting them.
b) Falsification is manipulating research materials, equipment, or processes, or changing or omitting data or results such that the research is not accurately represented in research records or reports.
c) Plagiarism is the appropriation of another person's ideas, processes, results, or words without giving appropriate credit.
d) Research misconduct does not include honest error or honest differences of opinion.
e) Research misconduct includes the destruction of, absence of, or accused person's failure to provide research records accurately documenting the questioned research.
Forms of misconduct
• Falsification• Obfuscation• Fabrication• Supression• Plagiarism• Self-plagiarism• Ghost writing
• Bare assertions• Improper authorship• Misappropriation• Bibliometric inflation
• Violation of ethical standards regarding human and animal experiments
http://en.wikipedia.org/wiki/Scientific_misconduct
Why research misconduct?
• Career advancement
• Competitiveness
• Laziness
• Ability to get away with it
Why me?
• Investigator
• Research mentor
• Former IRB member and chair
• Research misconduct investigator
•Son of George C. Lyketsos
George C. Lyketsos, MD, FRCPsych11 January 1917- 20 August 2011
• Professor of Psychiatry, National Kapodistrian Univeristy of Athens, 1974-1989
• Medical Director, Dromokaition Mental Hospital, 1947-1985
• Lived through the transition to modern psychiatry
Human subject researcher in an era before regulation
Dromokaition Mental Hospital
• Bequest of major philanthropist 1887
• Where thousands of patients lived, some for decades
• Where new therapies for mental illness where introduced in Greece
• Where community placement of most patients took place by the 1980s
• This was largely unregulated research
The introduction of ECT to Greece: from The Story of My Life (GCL, 1998)
The first patient finds himself
And then the time came for the great trial…of ECT in a patient. Thinking of those days I am surprised by my confidence. I had no doubt things would go well. I chose for the trial patient X who had been lost to the world…nobody had shown any interest in him for many years…That morning in March 1946…(the staff) brought X. He was catatonic…We laid him down on a sofa and placed the electrodes on his temples which we had already rubbed with salted water… I pressed the button for 10ths of seconds. A jerk followed… I increased the intensity…I pressed the button for a longer duration and after a few seconds the seizure happened. We became scared as the patient turned blue. We fell onto him to provide artificial respiration. Quickly, breathing returned and we took him to the ward where he fell asleep. Later we visited him. He had awakened and was active… I asked him “How are you?” and he ANSWERED “fine.” This gave us courage and we repeated the ECT after two days. After that we were able to communicate enough to find out who his relatives where who came to visit. He is the phenomenon and I think he still lives at Dromokaition. In total he had ten ECT. It did not cure him, but he was able to live at the level of social life of a developed psychiatric hospital.
Outcomes of ECT therapy
• Schizophrenia: N=75, 6-12 treatments– 12 (16%) full remission (mostly catatonic)– 17 (23%) partial remission– 46 (61%) no change—mostly “demented”
• Affective disorder: N=25– 18 (72%) full remission– 6 (24%) partial remission– 1 (1%) no change
Lyketsos GC, Arkalides N. The therapeutic method via electric shock at Dromokaition Therapeuterium. Results of 100 cases. (Experience of over 4,000 treatments.) Kliniki 1 December 1946
Tidbits of the ECT story
• Built their own machines (“cost 10 gold sovereigns to build and sold for 11”)
• Offered to most every patient• Consent was obtained when families
available or patients could discuss (no documentation)
About 30% of patients improved and left the hospital within the next year
Other examples of Dromokaition research
• Observational studies
• EEG research
• Frontal leucotomies
• Ancient Greek Drama therapy
• Rehabilitation methods
None of our contemporary processes followed
• Research happened
• Patients were helped
• Advances occurred
How is that possible?
INTEGRITY
Definitions: integrity
1. firm adherence to a code of especially moral or artistic values-INCORRUPTIBILITY
2. an unimpaired condition: SOUNDNESS
3. the quality or state of being complete: COMPLETENESS
http://www.merriam-webster.com/dictionary/integrity
But what is integrity really?
• An attitude
• A state of mind
• A commandment
• Must be cultivated and honed
• Occurs in a context
• A team sport: you are not alone
• Modeling critical to its development
Measuring integrity
• Choice of research we conduct– Why is the study important?– Would you put your mother in your study?
• How we look after our participants– How would you consent your sister/brother?– How would you monitor your ill child?
• How we report our findings

NPS accelerate onset of severe dementiaincluding mild NPS
Rabins et al, Poster P-145, AAIC, Paris, July 2011
NPS are “bad” for patients & caregivers
• Greater ADL impairment1
• Worse quality of life2
• Earlier institutionalization3
• Major source of caregiver burden4
• $10,000/year additional care costs5

Treating NPS is a high priority
• High utilization of treatments based on findings in general psychiatry– Antipsychotics, antidepressants, etc
• Little controlled research
• Safety concerns
• We undertook placebo controlled RCTs
The issues
• Placebo controls
• Vulnerable population

Seeking a paradigm shift: focus on 5 NPS to accelerate treatment development
• Psychosis
• Apathy
• Agitation
• Depression
• Sleep
Approach
• Phenomenology– Diagnostic criteria, prevalence, subtypes
• Assessment tools– Define relevant endophenotypes, biomarkers
• Neurobiology– What is known?– Useful to guide interventions?
• Interventions– Pharmacologic and nonpharmacologic-efficacy? – Change progression?

Citalopram for agitation in AD: Multi-center trial (R01AG031348)
• 200 patients with AD and agitation
• 9-week RCT: citalopram 30mg v placebo
• Psychosocial intervention for all
• First patient randomized Aug 2009
Can NSAIDs prevent AD?
• At least 22 studies and one meta-analysis1 including case-control, case-cohort, and prospective (incidence) studies
• 7 case-control studies of OA or RA with summary odds ratio (OR) 0.56 (0.44 - 0.77)
• 2 population (“case – cohort”) studies of RA with summary OR 0.19 (0.09 - 0.41)

Alzheimer Disease Anti-inflammatory Prevention Trial (ADAPT)
• Primary prevention RCT with two outcomes:– Incident Alzheimer Disease (AD)– Cognitive Decline
• Treatments vs. placebo– Conventional NSAID (naproxen 225 BID)– Selective COX-2 inhibitor (celecoxib 200 BID)
• Six sites: Baltimore, Boston, Phoenix, Rochester, Seattle, Tampa/Sarasota
• N=2422 aged 70+ with history of AD-like dementia in 1o relative: 437 at JHU
ADAPT in crisis
• Dec 2004—adenomatous polyps prevention trials suggest increased risk of cardiovascular events with celecoxib (OR~2.5)
• Two similar trials stopped Dec 17• ADAPT DSMB met week before and recommended continuation
• WHAT TO DO IN ADAPT?• Took the risk seriously especially in prevention trial• Considered re-consent and continuation, esp naproxen arm• Logistics got in the way: media effects on participants, concerns about
IRB review process, FDA hold on celecoxib trials
• ENROLLMENT AND TREATMENTS STOPPED• FOLLOWUP CONTINUED
Did we make the right decision?
• Stopped a trial mid-stream out of safety concerns, largely for pragmatic reasons
• Delayed an experiment that may have identified a preventive therapy for AD
• We may never know
Patient to research participant
Mrs. RF• Married, artist in her 80s; healthy• Closely connected with husband-agent• First seen as outpatient for depression• Did well on antidepressants• Developed AD dementia• Requested research participation• ADRC, GSI RCT, apathy Rx RCT
Research participant to patient
Mrs. EH
• ADAPT participant—her mother had AD
• During ADAPT followup diagnosed MCI
• Asked to become my patient
• Continues in ADAPT
• Several complex clinical issues
The issues
• My own patient in my own research
• Triage of what’s the right study
• Communication, disclosure, oversight
The next plunge
Final words: threats to integrity
Excessive focus on process
• Uses up resources and energy
• Gives the wrong signal that the process assures integrity
Research Integrity
• An attitude
• A state of mind
• A commandment
• Must be cultivated and honed
• Occurs in a context
• A team sport: you are not alone
• Modeling critical to its development
Johns Hopkins is a special place
