PRACTICAL APPLICATIONS OF BIOTECHNOLOGY
1. Bioprocessing technology

Uses whole living cells or components of them
to manufacture desired products.

Most common whole cells used are yeast and
bacteria (one-celled organisms).

Most common components are enzymes
(proteins that catalyze chemical reactions).

Cells isolated from animals and plants also are
used to produce desired products.
2. Genetic engineering

The technique of removing, modifying or adding
genes to a DNA molecule to change the
information it contains.

More specifically is known as recombinant DNA
(rDNA) technology.

The product of rDNA technology is known as a
genetically modified organism, or GMO.

Example: Gene for human insulin inserted into
E.coli → bacteria that make human insulin (a
biopharmaceutical).

Clinical Trials — A Closer Look
Clinical research and development
The Food and Drug Administration (FDA) is the main
consumer watchdog for numerous products: Drugs and
_____________ (prescription and over-the counter),
Food, Medical devices, ___________ feed and drugs,
Cosmetics, Radiation-emitting products (such as
___________________ and pagers)
The application to the FDA to request permission to
begin human testing is called an Investigational New
Drug application, or IND.
The evaluation of pharmaceuticals and
biopharmaceuticals is a highly _____________ process
requiring many _______ to prove a drug is safe and
effective.
This is known as the drug development process.
There are a number of steps in the new drug
development timeline.
The steps include:
► research and _____________ in the lab ►
testing in ___________ models (pre-clinical) ► several
phases of testing in ___________ (clinical trials)
Clinical trials are ____________________ designed to
distinguish a drug’s __________ from other influences.
Drugs must be thoroughly analyzed and tested in animal
models _____________ they are tested in humans.
Research and development in the lab
R&D involves initial synthesis and analysis of a
promising pharmaceutical OR development and analysis
of a biopharmaceutical produced in living cells.
On upcoming slides, the word “drug” applies both to
pharmaceuticals and to biopharmaceuticals.
Pre-clinical testing
When new drugs show promise in lab testing, studies
are designed to evaluate them further.
These studies in animals are referred to as “pre-clinical
studies.”
Pre-clinical studies help establish ________________
____________________________ of the treatment
if/when human studies begin.
Many new drugs and treatments are ______________
at this step because they are proven unsafe.
The IND permits the use of an investigational new drug
for the sole purpose of __________________________.
Phase 1 clinical trials
Drug is tested for its _____________ with the human
body.
Trials are conducted to determine the appropriate dose
range with regard to ________ and _____________
(NOT ______________).
Trials are conducted on a limited number (___-___) of
normal volunteers or patients (such as patients with
cancer or AIDS).
Phase 1 trials often take nine to 18 months to complete.
Many drugs are abandoned in Phase 1 testing because
of problems with safety or toxicity.
Phase 2 trials
Small-scale, well-controlled trials evaluate the
preliminary ________ AND ___________ in ____ to
____ patients with the disease or condition to be
treated.
May focus on dose-response, dosing schedule or other
issues related to preliminary safety and efficacy.
Often take one to three years to complete.
Additional _________ testing may be conducted at the
same time to obtain long-term safety data.
If studies show drug to be safe and useful, testing may
proceed to Phase 3.
Phase 3 trials
The most ____________ (and expensive) testing of a
drug.
These trials fully assess _________, efficacy and drug
dosage in a _________ group of patients with the
specific disease to be tested.
Conducted on larger (______s to ________s) and more
diverse groups of patients with the condition.
Make comparisons between the new treatment and a
placebo and/or the standard treatment.
Trials help to better understand the drug’s safety and
uncover any adverse effects.
Trials often take two to five years to complete.
New Drug Application (NDA)
Submitted to the FDA once all or most of the proposed
studies are completed.
Submitted if company believes adequate positive
information has been obtained to warrant a request to
market the drug.
Phase 4 clinical trials
Companies sometimes continue clinical trials of a drug
after it has been approved for marketing.
Phase 4 trials may be performed to learn more about
side effects and long-term risks and benefits.
Companies also may evaluate different formulations of
a drug (like _________________) or test the drug for a
different indication.
The FDA sometimes requires companies to conduct
Phase 4 trials.
Post-marketing surveillance
The NDA contains extensive data on the investigational
drug and results of the clinical trials.
The company must continue to report information
about new findings and problems after drug approval.
The NDA is many ______________ of pages long. The
FDA hopes that eventually they will be submitted
electronically.
_________________________ can report new findings
to the company or directly to the FDA (consumers can
report information to the FDA as well).
By law, the FDA has ___ days to decide if there is
enough information to continue with the NDA review.
By law, the FDA is required to make a final decision
within 180 days.
In practice this timeframe often is lengthened
(considerably) by mutual agreement.

Producing a Pharmaceutical or
Biopharmaceutical-The Manufacturing
Process
Process development
 Scientists and engineers begin to figure out how
to “_____________” production of a drug even
__________ it receives FDA __________.
 Manufacturing processes might be quite
different than the small-scale lab procedures.
Production
 Production of a pharmaceutical or
biopharmaceutical involves many different,
complex and lengthy steps:
 Synthesis (chemical or cell culture)
 Purification
 Formulation
 Final dosage form preparation
Step 1: Synthesis
 Order the raw materials needed to make the
product.
 Test all raw materials to be sure they meet
quality standards.
 For biomanufacturing, equipment and materials
need to be ____________to avoid bacterial and
other __________________ to the cell cultures.
 The product then is created.
 For pharmaceuticals, there are chemical
processes involved (chemical synthesis).
 For biopharmaceuticals, cell culture or
fermentation is involved.
 The product is referred to as the
“_______________________”
 For the biopharmaceutical, the original cell
culture is started in small bottles (around the
size of large ________________)
 As the cells grow and multiply, they are
introduced into a small __________________.
 Eventually they are grown in large bioreactors,
which can be several ______________ tall!
Step 1: Biosynthesis
A small bioreactor in the foreground, with a
larger one behind it.
Step 2: Purification

 A company is required to have a traceable,
written record of all processes and checks.
 “If it isn’t written __________, it doesn’t exist. If
it isn’t written down, it never _____________.”
Validation
 Validation proves that a manufacturing process
will ________________ produce the product to
predefined specifications.
 The operation of every part of the plant that
affects quality must be validated.
 If a manufacturing process is changed or if a
