1) The drug development process involves multiple phases of clinical trials to evaluate safety and efficacy, taking on average 10-15 years from discovery to approval.
2) Key players in clinical research include the FDA, study sponsors, principal investigators, institutional review boards, study coordinators, and study monitors.
3) Each player has distinct roles and responsibilities to ensure research is conducted properly and that human subjects are protected.
1. History & Overview of the Drug Development Process & Timeline Brown Bag lunch series (1/6) JoAnn Pfeiffer November 17, 2010
2. 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.

The motivating factors for legislative changes regarding food, drugs and cosmetics can be traced to significant societal problems, human tragedy, and governmental inefficiencyJungle: revealed the unsanitary practice in meat packing
First miracle drug
399 black men in late stages of syphilisMost were illiterate share croppers from the poorest county in AlabamaMost had never been to a doctor before.Received a free hot meal and medical treatment Subjects were never told that they had syphilis or the seriousness of the disease (tumors, heart disease, paralysis, blinding, insanity, & death)They were told they were being treated for “bad blood”Data for the experiment was to be collected from autopsies.
Became the cornerstone of the CFR
Teacher and learner separated during the test.Learner sits in chair with electrodes attached to his body.Teacher at control panel, asks multiple choice question.Learner gave wrong answer, administered a 45 volt electric shock, goes higher as continue.If do not respond, treated as wrong answerExperiment continues till: teacher requests to stop or a maximum 450 volt shock given 3 times in succession67.5% administered maximum shock
