Exhibit 99.1

           INYX SIGNS DEFINITIVE AGREEMENT TO ACQUIRE
               AVENTIS PHARMACEUTICALS PUERTO RICO

          - ACQUISITION WILL BE MATERIALLY ADDITIVE
                TO INYX'S REVENUES & EARNINGS

NEW YORK - December 17, 2004 - Inyx, Inc. (OTC BB: IYXI), a
specialty pharmaceutical company with a focus on niche drug
delivery technologies and products, announced today that it has
signed a definitive agreement with Aventis Pharmaceuticals, Inc.,
a member of the sanofi-aventis Group (NYSE: SNY), to acquire
certain assets and business of Aventis Pharmaceuticals Puerto
Rico Inc.  The acquisition, which is subject to completion of a
major contract transfer, is scheduled to close by March 31, 2005.
Financial terms were not disclosed, but Inyx said it expected to
be able to pay for the acquisition through non-dilutive
financing.

Jack Kachkar, M.D., Chairman and CEO of Inyx, said, "This
acquisition will be a `transforming event' in Inyx's corporate
development.  It will be materially additive in terms of the
assets and multi-year production contracts that we are acquiring,
as well as the greatly enhanced operating economies and new
strategic business opportunities that we are gaining, which will
enable our operation of this Puerto Rico complex to be profitable
from the start and provide a strong catalyst for growing Inyx's
consolidated revenues and earnings."

The Aventis operations in Manati, Puerto Rico consist of a high-
calibre pharmaceuticals production center that will provide Inyx
with a strategic base in the United States to complement Inyx's
present development and manufacturing facilities located in the
United Kingdom.  Moreover, this will provide Inyx with favorable
tax incentives, including a corporate income tax rate of 2%-7%
for 15 years in Puerto Rico as well as 90% exemption on property
tax, 60% exemption on excise tax and tax-free purchases on
materials and equipment on the Island.  In addition, Puerto Rico
is home to more than 20 leading pharmaceuticals companies, a
captive marketplace for Inyx to cultivate - both for new contract
clients and for strategic marketing partners of Inyx' own
proprietary products.

"Manati gives Inyx a strategic base for growing our company's
roster of clients as well as for introducing Inyx's own products
because it provides us with an operating center on this side of
the Atlantic that is needed to best serve the markets in the
U.S., Canada, Latin and South America.  Manati's facilities and
employees are very well suited for Inyx's niche aerosol drug
delivery technologies and products," said Dr. Kachkar.
The Manati complex consists of five buildings totaling about
140,000 square feet and extends over 9.5 acres, located in north
central Puerto Rico about 30 miles outside of San Juan.
Currently, Aventis employs approximately 330 people at Manati,
and Inyx said it will retain as many of these experienced and
skilled employees as economically viable.

Aventis is selling the Manati complex to Inyx because Inyx's
aerosol drug delivery technologies and expertise will enable
Manati, which no longer fits with Aventis' core capacity needs,
to continue to be a productive pharmaceutical center for the
benefit of the site's employees and customers and the local
economy of Puerto Rico, according to Martin Siewert, a senior
executive in Industrial Operations for Aventis.
