4. In the past most drugs have been discovered either by
identifying the active ingredient from traditional
remedies or by serendipitous discovery.
But now we know diseases are controlled at molecular
and physiological level.
Also shape of a molecule at atomic level is well
understood.

5. In an analysis of 98 companies over a decade, the average
cost per drug developed and approved by a single-drug
company was $350 million.
But for companies that approved between 08-13 drugs over
10 years, the cost per drug went as high as $5.5 billion,
due mainly to geographic expansion for marketing and
ongoing costs for Phase-IV trials and continuous
monitoring for safety.
7. Drug discovery is the process through which
potential new medicines are identified. It involves a
wide range of scientific disciplines, including
biology, chemistry and pharmacology.

9. The process of bringing a new pharmaceutical drug to
the market once a lead compound has been identified
through the process of drug discovery. It includes pre-
clinical research on microorganisms and animals,
filing for regulatory status, such as via the United
States Food and Drug Administration for
an investigational new drug to initiate clinical trials on
humans, and may include the step of
obtaining regulatory approval with a new drug
application to market the drug.

12. New Drug Application (NDA) contains data which
when submitted to FDA's Centre for Drug
Evaluation and Research, Office of Generic Drugs,
provides for the review and ultimate approval of a
generic drug product. Once approved, an applicant
may manufacture and market the generic drug
product to provide a safe, effective, low cost
alternative .
13. New drug applications (NDAs) require clinical trials
using the candidate chemical compound for safety
and efficacy, usually in centers in multiple states.
The IND is the process by which an exemption to
the law is obtained.
Studies in humans can only begin after IND is
reviewed and approved by the FDA and an
institutional review board (IRB).
14. The FDA reviews and evaluates new drugs based on
evidence presented from the clinical research
studies performed by the drug sponsor-typically a
pharmaceutical company.
The Center for Drug Evaluation and Research
(CDER) is the largest of the FDA’s five centers and is
responsible for prescription and over-the-counter
(OTC) drug safety and efficacy.
15. IRBs ensure the rights and welfare of people
participating in clinical trials, both before and during
trial participation.
IRBs make sure that participants are fully informed
and have given written consent before participating
in studies.
17. The full cost of bringing a new drug (i.e., new
chemical entity) to market – from discovery through
clinical trials to approval – is complex and
controversial. Typically, companies spend tens to
hundreds of millions of U.S. Dollars.
One study assessed both capitalized and out-of-
pocket costs as about US$1.8 billion and $870
million, respectively.

widespread use of
electronic health records
(EHR) for clinical research
purposes

Patient Recruitment Costs
(per patient): Reduced by
35.9%
Number of Patients (per
site): Reduced by 12.3%
25. BARRIER MITIGATION MEASURES
Encourage sponsors to carefully
consider their trial enrolment
restrictions
Encourage sponsors to simplify
clinical trial protocols and plan
carefully to avoid costly
amendments, whenever possible;
ensure that they have a clear
understanding of what is required
by FDA and what is superfluous

developed specifically to treat a rare medical condition,
the condition itself being referred to as an orphan
disease.

33. There is a financial cost to develop new drugs—and it’s a big one.
There is also a big cost to not developing new drugs, and that cost
can be both financial and human.
There are ways to make drugs less expensive—i.e., cut down on
some of the bureaucratic oversight or lengthening the patent life,
which means the manufacturers would have more time to recoup
their investment—but both efforts would require a major
legislative push
If the cost of creating new drugs is high, the cost of not having any
new drugs is immeasurable.
