Forty Five
New Active Substances Launched in 1998
A total of 45 new active
substances (NAS) were launched worldwide in 1998, slightly
down on the 1997 total of 50 NAS, but on a par with the previous
two years of 44 and 45 respectively, in 1996 and 1995. These
figures are monitored by IMS HEALTH's new pharmaceuticals
introductions service, Drug
Launches. Thus, the message is that innovative R&D is
alive and well.
Decline in NAS from Japan
So what has changed over the last five years? A significant
shift has occurred with respect to first world launches by
country according to IMS HEALTH's Pharmaceutical World
Review. In 1994, Japan led the field with a massive 23
first world launches, whilst in 1998 Japan only accounted
for 4 first world introductions.
New Active Substance by Country of 1st Launch

Reasons include: |
- A less favourable situation
regarding NAS in the domestic market, with shorter times
to recoup R&D outlay.
|
- NAS are no longer sustaining
the high prices they originally attracted in the Japanese
NHI.
|
- Long approval time taken
by Japanese authorities
|
- In the past, many
drugs developed in Japan stayed in the domestic
market and did not reach US or European markets.
Now most of the NAS are international products and
have been licensed out at various stages along the
way. However, in general they still take time to
enter European and US markets despite earlier licensing
in activity. By year-end 1998 none of the NAS launched
in Japan as their first market had penetrated any
other world market. Conversely none of the other
41 NAS had reached the Japanese market by year-end
1998. Indeed, nearly 70% of pharmaceuticals approved
in the USA since 1991 have not yet been approved
in Japan, according to PhRMA. This situation should
change as Japan has formally undertaken to reduce
average review times for new drugs to one year from
April 2000, and to accept foreign data in applications,
under a bilateral agreement reached with the USA
at the G8 meeting in summer 1998. The current Japanese
review period should only take 18 months, but in
general the time taken is nearly twice that according
to IMS HEALTH's Pharma
Prognosis International.

| NAS Increases
in the US |
In contrast, US first world launches
of NAS have risen dramatically; in 1994 only 7 NAS were introduced
in the US as their first market, but by 1998 first US introductions
amounted to a massive 32 - representing 71% of NAS.
What have been the drivers of this change? |
- Increasing acceptance of
clinical trials conducted in Europe.
|
- The US FDA approval process
has long been considered as the most stringent in the
world, demanding very extensive trials, conducted predominantly
in the US. There has been a general acceptance more recently,
however, of the trials conducted in Europe.
|
- The sustained high growth
rate in the US pharma market
|
- This has encouraged
multinational companies to concentrate efforts on
the more buoyant US market first and then pick up
on EU as a close secondary concern
|
|
- The US FDA Orphan Drug Designation
|
- The US FDA's accelerated
approval process for drugs classified as having
significant contribution over drugs already on the
market or filling a niche not already satisfied
means that the approval process in the US is accelerated
at the final stages in the US, overtaking European
first approvals. This procedure, which has been
in place for several years now, has encouraged and
accelerated the development process for several
important new drugs for restricted markets. The
EU has yet to finalise its orphan drug policy, hence
approval of these drugs takes proportionally longer
than in the US. Another factor which slows down
the process in some European countries is that once
they have passed the first hurdle of the EMEA, they
then have to wait several months, particularly in
France and Italy, to receive price approval.

Sixteen of the 32 drugs introduced in the US as their first
market in 1998 did not reach any other markets by the end
of 1998. A further 5 drugs only reached either Puerto Rico
and/or Canada by year-end. Only 7 of the 32 drugs had reached
one or more of European market by year-end.
The UK had been steadily increasing in popularity as the first
country of launch, rising from 4 in 1994 to 9 in 1997, but
this trend came to an abrupt halt in 1998, when first introductions
in the UK dropped dramatically to just one in 1998.
R&D Country of Origin
When considering the actual country of R&D for the drug by
the corporation nationality, rather than the local company,
the trend is reversed. It is of interest to note, however,
that a number of the drugs introduced in the US as their first
market actually came from European companies. German corporations
are responsible for 5 of the 10 US first introductions not
developed by US corporations. |
