Goal

Through training on the conduct of human subject research the Velos staff will acquire a better understanding and knowledge of the steps and requirements in the day-to-day operations of a clinical trial. Through a better understanding of clinical trial operations the Velos staff will be able to respond more effectively to client requests and requirements.

Historical Events

Pre 1906: all drugs could be bought or sold like any other consumer good

Pure Food & Drugs Act (1906) Upton Sinclair: “The Jungle” Prohibits interstate commerce of

misbranded or adulterated foods, drinks, and drugs

Regulated product labeling Did not address drug safety or efficacy

Page 6: Clinical trial brownbag session 1 nov 17 2010

Historical Events

The Federal Food, Drug and Cosmetics Act—1938

Sulfanilamide: treat streptococcal infections

Massengill Co: introduced a liquid form (1937)

107 people died that year Contained diethylene glycol First time FDA required that drugs must

be safe before being introduced to the market.

Nuremburg Code (1947-1948) Nuremburg war crimes trials: Nazi experimentation Ten points for legitimate medical research Voluntary consent; fruitful results; based on animal

experimentation; free of unnecessary physical or mental suffering; end result cannot be death or disability; risk/benefit; conducted by scientifically qualified persons; subject at liberty to withdraw; terminate if cause to believe harm; adequate facilities

Thalidomide

Thalidomide (1950’s & 60’s) Approved as sedative in Europe and

Japan Mfg. sent “samples” to US physicians Patients not informed that the drug was

investigational in US Used for morning sickness > 10,000 children in 46 countries were

born with deformities in late 1950’s and early 1960’s

Milgram Study

The Milgram Study (1961 – 1962)67.5% administered the max shock

(450 V) Teacher – Learner Teacher ask multiple choice questions Administer a shock if answer incorrect Start at 45 volt, could go up to 450 volt

shock▪ All paused to question experiment▪ None refused prior to 300 volt shock▪ Female subjects –same results, higher stress

Kefauver-Harris Amendment – 1962 Subjects informed of experimental

nature Informed consent must be obtained Safety and efficacy must be proven

prior to approval to marketBelmont Report – 1978 Respect Beneficence Justice
