Principles and Practice of Pharmaceutical Medicine

Patients and families


The motivation of those with the disease or those
with relatives with the disease is clear – they want
better treatments that are affordable and will
improve the quality of life for the patient.


Physicians and other healthcare
providers


The motivation of these people is also clear – they
seek to find better treatments for their patients
and are often willing to test new drugs in clinical
trials.


Academicians


Orphan drugs offer research opportunities for
scientists and clinicians. Another important moti-
vating factor are the opportunities presented for
career enhancement.


21.6 Specific sources
of information
on orphan drugs

The Food and Drug Administration (FDA) pub-
lishes an annual list of orphan drugs that have been
approved for marketing since the signing of the
Orphan Drug Act in 1983. They also publish a
monthly list of drugs that have received orphan
drug designation within the last month and an
annual cumulative summary of the current desig-
nations. There is also a home page on the Internet
and an annual publication of grants to evaluate
orphan drugs in clinical trials.
Most specific disease organizations, as well as
umbrella disease organizations, provide infor-
mation of relevant diseases for members and
sometimes for researchers, and the public.
These groups may also provide current scientific
information. For example, the NORD database
is a valuable source of information for many


groups of people interested in a particular
disease.

21.7 Discovery, development,
marketing and distribution
of orphan drugs

The process ofdiscoveringnew orphan drugs is not
different from that used to discover drugs for more
common diseases (Spilker, 1994). This is a broad
topic and will not be discussed further.
As with discovery, the methods used todevelop
drugs for rare diseases do not differ from the meth-
ods used to develop drugs for more common dis-
eases in terms of strategies created, methodologies
used and criteria for success (see Chapter 2.2).
However, certain differences in quantity of data
exist. If there are only 500 patients with a specific
disease, it is probably impossible to have two ran-
domized, well-controlled placebo trials. Nonethe-
less, the quality and amount of manufacturing data
required for regulatory submissions do not differ
for orphan drugs than for more common drugs.
The same marketing tools are available tomar-
ketorphan drugs and non-orphan drugs. Probably
the greatest difference between orphan and non-
orphan drugs from a marketing perspective is that
the amount of money spent on orphan drugs will be
significantly less than that for non-orphans.
Although the same mix of marketing tools can be
and are often used, the number of symposia to be
held and the number and size of advertisements
will usually be fewer. Another exception is that the
use of sales representatives to promote a new
orphan drug may be nonexistent. However, a
large company may in fact be developing the
orphan drug so that the sales representatives can
discuss the orphan drug (and non-orphans too),
whereas a small company may have decided to
develop an orphan because sales representatives
are not necessary to promote the product.
Distributionmethods differ more between orphans
and non-orphans more than the other categories
discussed in this section. Conventional drugs are
generally sold through wholesalers, as well as
