Q

generic industry: manifacturing

A

Manufacturing: Vast majority of generic pharmaceuticals
sold in Canada are produced domestically (drug products not drug
substances)

20
Q

lessons learned from covid 19: manifacturing

A

Insufficient domestic manufacturing left Canada at the mercy
of other countries to access drugs manufactured in foreign
plants. US implemented an emergency law that prohibited
Pfizer and Moderna from exporting the vaccine until US needs
were first met.

21

38
Q

A biosimilar and its reference biologic drug can be shown to be….

A

-highly similar, but not identical.
-biologic drugs are:

demonstrate that it is highly
similar to its reference biologic drug

Q

Reference Biologic Drug: manifacturers must:

A

manufacturers must independently demonstrate the quality,
efficacy and safety of the drug.

41
Q

biosimilar: manifacturers must independently demonstrate what?

A

the quality of the drug and perform comparative studies to demonstrate highly similar structure, function, efficacy and safety to a previously authorized reference biologic drug.
