2
So you want to be a clinical investigator David Robertson
3
Kinds of Clinical Research Human gene function Human cell function Clinical pathophysiology Clinical pharmacology (therapeutics) Clinical trials Outcomes Epidemiology
4
Patient Oriented Research Human gene function Human cell function Clinical pathophysiology Clinical pharmacology (therapeutics) Clinical trials Outcomes
5
Interdependency Preclinical (Bench) Research –Reductionist Clinical Research –Integrative The interdependency is now absolute Bench research is the lingua franca Epidemiology
8
Aphorisms You have to take care of yourself Enjoy writing grant proposals Select a mentor who is successful and who fights for proteges Help your mentor succeed; you may get his/her job Never do something that might be wrong: in research there may be no second chance; in clinical research there is usually no second chance

GENOME PROTEOME PHYSIOME/ INTERMEDIATE PHENOTYPE CLINICAL RESEARCH: OLD PARADIGM
10
Intermediate Phenotype (Physiome or Phenome) Physiology Visualization (PET, fMRI,…) Physiological Assay (BME instruments) Analytical Assay (chemical, proteome)
11
Patient-Oriented Research: The Old Paradigm Homogeneity Norm Phenotype-Driven Aim: Intermediate Phenotype Few Patients Relatively Data-Poor Hypertension High Blood Pressure Plasma Renin Activity Levels Maybe 6-20 Simple Statistics
12
GENOME PROTEOME PHYSIOME/ INTERMEDIATE PHENOTYPE CLINICAL RESEARCH: NEW PARADIGM
13
Patient-Oriented Research: The New Paradigm Heterogeneity Intermediate Phenotype-Driven Aim: Genotype Many Patients Relatively Data-Rich Non-Modulators RBF Angiotensin Dependence Polymorphism Familial Subgroups Complex Statistics
14
GENOME PROTEOME PHYSIOME/ INTERMEDIATE PHENOTYPE CLINICAL RESEARCH: NEXT PARADIGM ENVIRONOME
15
Be a great physician Study your patients Study your books Study your journals Study OMIM + links
16
Study your patients 2000 patients during residency Listen to your patients’ observations Master each H&P finding Rationalize each lab abnormality Maintain access to all 2000 H&Ps and summaries: they are your magnum opus Reexamine them each decade
17
Maintain a targeted practice Focus on one lifetime clinical area Choose that area with care Limit your practice to that area * Limit your practice to 10% effort * Manage all aspects of their care Look for heterogeneity Think laterally about your patients * may be difficult to do in 2003
18
Guides for Master Clinicians P. A. Tumulty: The Effective Clinician D. W. Cathell: The Physician Himself J. M. Orient: Sapira’s Art and Science of Bedside Diagnosis
19
Develop Good Habits Make your tasks educational Be competent; know your methodology Remember that a scientific career is a pleasure but also a business
20
Career Advice: The Far Side C. J. Sindermann, Winning the Games Scientists Play (Cambridge: Perseus) 2 nd edition. 2001 Richard J. Johns, How to Swim with Sharks, Trans Assoc Am Physicians. 1975; 88: 44- 54.
21
Periodicals for Master Clinicians New England Journal of Medicine Journal of Clinical Investigation Nature, Science, Cell The New York Times Consider The National Enquirer
22
At any given moment, have … 6 projects in planning 4 projects in process 2 projects in press ….Victor A. McKusick, Advice to Housemen, 1964
23
Education Medical Scientist Training Program Clinical Scholars Training Program Master’s in Clinical Investigation –Genetics –Human Physiology –Biostatistics and Study Design –Bioinformatics
24
Professional Organizations Association of American Physicians (AAP) American Society for Clinical Investigation (ASCI) American Federation for Medical Research (AFMR) Association for Patient-Oriented Research (APOR)
25
Practicing Clinical Research Be a clear thinker Hypothesis-testing is the liturgy of POR Understand “biomarkers”
26
Biomarker 1)Diagnostic Tool 2)Indicator of Disease 3)Disease Staging Tool 4)Tool to Monitor Intervention
27
Clinical Endpoint A variable that reflects how a patient feels, functions, or survives.
28
Surrogate Endpoint A Biomarker intended to substitute for a clinical endpoint
29
The Perfect Surrogate THERAPY SURROGATE CLINICAL ENDPOINT
