Clinical trials

Clinical trials are research studies designed to evalauate forms of health care interventions such as drugs in order to deem them safe and effective for human use 

History and the later implications

The use of humans in clinical trials can be seen when the Nazi doctors carried out medical experimentation on prisoners of war during WW2. The subsequent trials of war criminals involved then led to the Nuremberg Code, which was the one of the first ethical guidlelines in which researchers should follow. It has key 10 principles, these are :

1. Voluntary consent is essential 

2. The research should be for the good of society as a whole 

3. Research should be based on previous knowledge e.g. animal studies

4. Avoid uncesscary physical and mental suffering 

5. Research should be avoided if death will occur

6. Risk should be assessed and should never exceed the benefits

7. Should take place in adequate facilitties 

8. Conducted by qualfied personel 

9. Withdrawal must be explained to participants 

10. Research should be halted following risk or injury
