Q

What is parametric release?

A

Release of terminally sterilized LVPs based on key parameters of a validated sterilization process, instead of results from batch sterility testing.

Q

what are the diff types of contaminants?

A
  • intrinsic contaminants (impurities): present inherently in API, excipients and packaging materials -> often specific in nature
  • extrinsic contaminants (cross contaminants) -> originate externally, often non specific in nature

16
Q

How is process validation carried out?

A

On at least three consecutive full scale batches.

17
Q

What are the steps of process validation?

A

1) establish critical quality attributes (CQA)
2) identify critical processes parameters (CPP)
3) design sampling plan
4) design testing plan
5) set acceptance criteria
6) perform statistical analysis (intra and inter batch) for the 3 batches

18
Q

What is a herbal medicine?

A
  • herbal medicine is a medicinal product
  • contains 1 or more herbal substances as active ingredients eg ginseng and lingzhi
  • active ingredients not synthetic, herbal in nature
  • inert ingredients can be synthetic
19
Q

What is a traditional medicine?

A
  • traditional medicine is a medicinal product
  • contains one or more traditional substances as active ingredient
  • traditional substance include herbal animal and mineral material.
  • herbal medicine is a subset of traditional medicine
20
Q

What is the current regulatory status of THMP?

A
  • lack of harmonized GMP standard for THMP

- minimal product quality requirements (only have limits for microorganisms and toxic heavy metals)

21
Q

What are the challenges in regulating THMP?

A
  • harmonization of GMP standard for THMP (PICS GMP standard annex 7 us a good starting point for global harmonization)
  • harmonization of quality standard for THMP -> EMA guidance note is a good starting point for harmonizing quality (impt to control water quality)
  • combatting adulterated THMP
  • levelling up cottage THMP industry
22
Q

What are the 2 biotechnologies used?

A
  • recombinant DNA technology involving bacterial cell

- hybridoma technology using mammalian cell

23
Q

What are the major steps in manufacturing a biotech medicinal product?

A
  1. cell banking: MCB and WCB
  2. cell cultivation: fermentation for microbial cells and culturing for mammalian cells
  3. harvesting: lysis for microbial cells and centrifugation/filtration for mammalian cells
  4. purification: remove impurities via chromatography
  5. viral clearance - need to validate viral clearance process
  6. batching and storage of bulk biological API - can produce in sub lots and pooled as bulk batch ; store in refrigerators or freezers
  7. formulation, packaging and release of finished product (injection) - into injection only
24
Q

What do we test for at cell banks?

A
  • genetic stability
  • endogenous viruses (for mammalian cell lines)
  • residual DNA (mammalian cell line)
  • adventitious vriuses introduced during sampling or transfer process
25
Q

When to split upstream vs downstream processes?

A

Cuts off after harvesting and clarification.

26
Q

What are the types of fermentation?

A
  • batch fermentation (closed system)
  • continuous fermentation (open system)
  • fed batch fermentation (in between)
27
Q

what are the types of cell culturing?

A
  • anchored system

- suspension system

28
Q

what should nutrient media not contain?

A

BSE prions

29
Q

what are some things to note about the ASEAN biopharmaceutical industry?

A
  • still at nascent stage
  • mainly produce vaccines
  • biopharmaceuticals are currently excluded from the scope of the ASEAN Mutual Recognition Agreement on GMP inspection
30
Q

What is ALCOA

A

Attributable, Legible, Contemporaneous, Original and Accurate

31
Q

How long to retain records for?

A

batch manufacturing records - 1 year after batch expiry

for clinical trial products, at least 5 years after clinical trial

32
Q

What are the types of documents?

A

Instructional: SOP, batch manufacturing formula and site master file
Evidential: Records and reports (most DI problems)

33
Q

What is metadata?

A

Metadata describes data (data of data)

34
Q

what does the ASEAN sectoral MRA on GMP inspection not include?

A

Biopharmaceuticals and APIs

35
Q

What are the ASEAN Listed Inspection Service (LIS)?

A 
singapore 
malaysia 
indonesia 
thailand 
philippines
