| New
drug delivery system for biopharmaceuticals to offer cheaper,
more stable preparations with fewer side effects and greater
patient compliance
Controlled
Therapeutics (Scotland) Limited, East Kilbride, Scotland,
has today secured a half million pound (GB £500,000
/ US $835,000) award from the UK Government via the Scottish
Executive Spur plus programme to assist in the development
of its next generation, polymer drug delivery system.
The one
and half million pound (GB £1.5m / US $2.5m) project
to develop a new biodegradable dosing system for both classical
and the new biopharmaceutical drugs (peptides and proteins),
such as interferon and EPO, is now underway at Controlled
Therapeutics' R&D and manufacturing headquarters in Scotland.
Dr Magnus
Nicolson, Controlled Therapeutics' Managing Director, said:
"Unlike Pegylation, our new technology does not result
in the chemical modification of the drug". Pegylation
is the leading drug delivery technology, used with such biopharmaceuticals
as interferon for the treatment of hepatitis C.
He added,
"In our new linear polymers the drug is trapped in the
pores within the hydrogel matrix until it escapes, either
by erosion of the matrix or by diffusing out of the delivery
system into the systemic circulation. Importantly, both processes
can be timed to enable sustained release of the drug."
Dr Janet
Halliday, Research and Development Director added: "Hydrogel
matrices are friendly environments for proteins and we believe
our formulations will greatly increase the stability of these
drugs, giving our preparations significantly greater storage
stability and longer shelf life."
She added,
"One of the main advantages offered by this delivery
system will be predictable drug release, avoiding the spiking
often seen with this type of product. As a consequence, our
formulations should produce fewer side effects for patients.
It is hoped that the reduced frequency of dosing required
using the new linear polymers will increase patient compliance,
thus lowering the cost of therapy."
This latest
development for Controlled Therapeutics follows on from the
success of their first product, the Cervidil®/Propess®
vaginal insert, which currently enjoys 85% market share in
the US for cervical ripening in women during childbirth.

Controlled
Therapeutics is a drug delivery company founded in 1986
employing 54 staff at its purpose built facility in Peel
Park Campus, East Kilbride, Scotland. It is a wholly owned
subsidiary of Cytokine PharmaSciences, Inc., a private
global biopharmaceutical company based in Pennsylvania,
USA. |

The
company's lead product, called Cervidil® in the US
and Propess® elsewhere, was launched in 1995 and is
used for cervical ripening in women during childbirth.
This product is currently manufactured and exported from
the East Kilbride facility to over 30 countries worldwide.
In addition, more than 20 other countries have gained
regulatory approval for Cervidil®/Propess® and
a phased program of product launches will take place over
the coming years. By 2002 over 2 million children had
been safely delivered thanks to Cervidil®/Propess®. |

The
linear biodegradable polymer system will be used to deliver
bio-molecules which are of increasing commercial importance
in the US $390 billion (2001) global pharmaceutical industry. |

Controlled
Therapeutics' new polymer drug delivery system is designed
to dovetail with the first raft of biopharmaceuticals
now coming off patent (and subject to generic competition)
and the new bio-pharmaceuticals now gaining approval.
The pharmaceutical industry, both generic companies and
market leaders, are looking for better delivery systems
for their drugs. Controlled Therapeutics believe their
bio-absorbable hydrogel matrices will be of interest to
a large number of companies seeking a better way to deliver
their drugs. |

Controlled
Therapeutics would be pleased to hear from pharmaceutical
and biotechnology companies to form co-development partnerships. |
