  5. early stage –> pharmacokinetic and toxicology test in animal, living cells and computational models
  6. lead optimisation
  7. preclinical testing –> test safety of drugs on animals
24
Q

What is the purpose of phase 1 clinical trial?

Study These Flashcards
A

to discover if the drug is safe

e.g. pharmacokinetics, pharmacodynamics, side effects

25
How many test subjects are there in phase 1 clinical trials?
20-100 HEALTHY volunteers, usually conducted in hospitals
26
What is the purpose of phase II clinical trials?
1. To evaluate the effectiveness of the drug in treating an illness or medical condition 2. To examine the safety, possible side-effects and potential risks. 3. To analysis the optimal dose and schedule of using the drug
27
How many test subjects are there in phase II clinical trials?
100 to 500 patients with disease or condition under study.
28
What is the purpose of phase III clinical trials?
1. To test in a large group of patients to show safety and efficacy of the drug. 2. Comparing with existing treatments or placebo 3. Provide primary basis for benefit-risk assessment and core information.
29
How many test subjects are there in phase III clinical trials?
Patient no. about 1000 to 5000 from multiple sites with many investigators.
30
What happens after completion of all 3 phases of trial proves that the drug is safe and effective?
submit to Health Authorities for marketing approval.
31
What is required for new drug application and approval requirement?
1. registration dossiers: clinical and manufacturing data 2. certificate from country of origin and referenced countries 3. local clinical trial (if required) 4. GMP requirements 5.Bioavailability/Bioequivalent studies (BABE) required for some generic product registration
32
What are Bioavailability/Bioequivalent studies (BABE) ?
Bioavailability -- rate and extent to which the active ingredient of a drug is absorbed and becomes available at the site of action Bioequivalence -- compares the bioavailability of the active ingredient from two different drug formulations.
33
What are the 'drug-approving' agencies in USA, Europe, China and Hong Kong?
- In USA – US Food and Drug Administration (USFDA) - In Europe – European Medicines Agency (EMA) - In China – National Medical Products Administration (NMPA) - In Hong Kong – The Department of Health (DoH)
34
What is the purpose of phase IV clinical trial?
Post marketing studies – to collect additional information of the drug about benefits, optimal dose or possible risk. --> harmful side effect observed --> product withdrawn from market
35
Name a drug which was withdrawn from market after phase IV clinical trial
Vioxx an anti- inflammatory and pain killer, was found to have serious cardiac side effects in phase 4 trials and was withdrawn from market.
36
What is the average cost of developing a drug?
USD 3.5 bilion pharmaceutical companies spend 15-30% on R and D
37
What are the current global trends in R&D?
1. More R&D investment in new technologies like biopharmaceuticals eg. biologics, gene and cell therapy. 2. Collaborate with outside partners like research centers , universities and biotech companies, including small emerging biopharma companies for new drug discovery. 3. Focus more on top product candidates with foreseeable high sales/profit potential and higher probability for commercialization like anti cancer drugs.
38
The WHO GMP for pharmaceutical regulators in developing countries is less strict. True or False
True
39
What is GMP's objective?
To reduce risks inherent in pharmaceutical production to ensure adequate safety and quality of drug such as 1. contamination (contagious microbes) 2. cross-contamination 3. mix ups 4. wrong labelling
40
What are some guiding principles in manufacturing of pharmaceuticals?
- Hygiene of the manufacturing facilities. - Prevention of cross contamination of drugs. - Manufacturing process clearly defined and controlled. - Records well kept during manufacturing. - Well trained workers. - Records of distribution from batch to batch. - Recall system in place.
