Explanation:

In the medical sector, the right of an individual is highly sort after before an decision is taken regarding to the patient's health. For example, a patient decision would be required before an operation is carried out on him irrespective of the critical state of the medical issue.

In the case of the 46-year-old man, it is the right of the man to take the decision whether to withdraw from the research drugs and embark on the commercially available treatment drug.

What the doctor (investigator ) can only be able to do is to offer all informations regarding to the new treatment drugs that would allow the patient make informed decision.
