Encouraging Human Trial Data Presented at International Cancer Conference for Progen's PI-88
Monday November 25, 9:30 am ET

BRISBANE, Australia--(BUSINESS WIRE)--Nov. 24, 2002--Progen Industries (ASX:PGL - News; Nasdaq:PGLAF - News) -- Encouraging interim clinical trial data on Progen Industries' lead cancer drug, PI-88, has just been presented at an international cancer conference. Dr Scott Holden, co-investigator on the trial at University of Colorado Health Sciences Centre USA, presented data from the Phase I/II trial that shows PI-88 is well tolerated and demonstrates encouraging anti-cancer activity in some patients with advanced cancer.

The conference is organised by the premier European cancer research society, the European Organisation for Research and Treatment of Cancer (EORTC) in association with the American Association for Cancer Research (AACR) and the American National Cancer Institute (NCI).

Dr Holden explained: "This is the first time that scientific data from human trials of PI-88 has been presented publicly. We are working with patients with very advanced malignancies including melanoma and renal-cell carcinoma and we have been very impressed by the effects of PI-88. Not only was there little sign of toxicity, but progression of advanced cancers in particular patients has also been retarded for extended periods. Some patients with advanced melanoma have had stable disease over an 8-16 month period and are continuing treatment. In one of these patients the size and number of secondary lung cancers have reduced after commencing treatment.

"We will closely monitor patients' improvement and continue providing treatment as long as patients continue to positively respond to PI-88 treatment," he said.

Dr Robert Don, VP Research and Development at Progen Industries said: "This is a very significant milestone for Progen. Our internal preclinical animal studies showed that PI-88 retards the growth of tumours by both inhibiting new blood vessel growth (angiogenesis) and reducing the spread of the disease (metastasis).

"External validation that PI-88 administered subcutaneously is well tolerated and demonstrates anti-tumour activity is extremely heartening for the company. However caution should be exercised in over interpreting the data at this stage."

PI-88 is a semi-synthetic sulphated oligosaccharide that has several modes of action. In animal models it has been shown to block tumour growth by preventing angiogenesis by inhibiting fibroblast growth factor. It has also been shown to block the spread of cancer (metastasis) by inhibiting the enzyme heparanase, which allows cancer cells to escape blood vessels. Finally, PI-88 stimulates sustained release of a molecule known as TFPI (or tissue factor pathway inhibitor) from cells lining the blood vessel wall. TFPI is one of the body's natural inhibitors of new blood vessel growth.

Progen Industries Limited (www.progen.com.au) is a Brisbane-based, internationally focused biotechnology company committed to the discovery, development and commercialisation of small molecule pharmaceuticals: potent, selective inhibitors of carbohydrate-protein interactions implicated in a range of human illnesses. The company's lead drug candidate, PI-88, is under development as a potential treatment for cancer.

Progen also operates two commercial business arms, a GMP certified pilot manufacturing facility that provides Contract Services for 3rd party drug manufacturing development and scale-up for early stage clinical trials, and a domestic distribution franchise for major international Life Sciences companies.

This has always seemed like a synthetic heparin to me, and we've seen projects like that fail, fail, and fail.

European Commission Approval for Zavesca(TM) European Launch of Type 1 Gaucher Treatment in Spring 2003
Tuesday November 26, 2:05 am ET

OXFORD, UK and ALLSCHWIL, Switzerland, Nov. 26 /PRNewswire-FirstCall/ -- Oxford GlycoSciences Plc (LSE: OGS, Nasdaq: OGSI) and Actelion Ltd (SWX: ATLN) today announced that the European Commission has granted Marketing Authorisation for Zavesca (INN: miglustat), the first oral treatment for patients with mild to moderate type 1 Gaucher disease for whom Enzyme Replacement Therapy (ERT) is unsuitable. (Full prescribing information in the English language is available at ogs.com )

This approval follows the positive recommendation made by the Committee for Proprietary Medicinal Products of the European Agency for the Evaluation of Medicinal Products in July 2002.

Under the terms of their worldwide licence agreement for Zavesca (see today's separate release), OGS will transfer the Marketing Authorisation to Actelion Ltd, the Swiss biopharmaceutical company. Following this transfer, Actelion will market the drug throughout the European Union, with launch of Zavesca expected to occur in spring 2003.

The European Commission has granted marketing authorisation under exceptional circumstances for Zavesca, requesting that follow-up safety data derived from a post-marketing surveillance programme and additional clinical information is provided to the authorities on a regular basis. Actelion has adapted its unique data capture and reporting system to satisfy this regulatory commitment.

Commenting on Zavesca's approval, Tim Cox, Professor of Medicine at the University of Cambridge and Vice President for the European Working Group on Gaucher Disease, said, "Type 1 Gaucher is a debilitating disease and not all patients are suitable for the one currently available therapy, ERT. The availability of this first oral treatment is very welcome."

David Ebsworth, Ph. D., Chief Executive Officer of OGS, added, "We are delighted to receive Marketing Authorisation for our first drug; this is a major achievement for the Company. With this approval, OGS has succeeded in taking a drug candidate through the development and regulatory processes, to marketing approval."

Christian Chavy, President of Actelion Europe, said, "Zavesca is an important additional treatment option for Gaucher disease. We believe that our specialised regulatory, marketing and pharmacovigilance network established for our first product Tracleer(TM) will ensure that Zavesca reaches treating physicians and their patients throughout Europe."

About Gaucher disease

Gaucher disease is a rare genetic disorder, which results from reduced activity of glucocerebrosidase, an enzyme responsible for glycosphingolipid (GSL -- a subclass of fats) metabolism. Symptoms include enlargement of spleen and liver, bone disease and anaemia.

Treating Gaucher disease with Zavesca

Zavesca is an oral inhibitor of glucosylceramide synthase, a key enzyme involved in GSL biosynthesis. The rationale for the use of Zavesca is to help balance the overall level of GSLs by inhibiting their production or synthesis -- termed 'substrate reduction'.

Zavesca regulatory background

European Commission approval of the centralised application for Zavesca results in a single marketing authorisation with unified labelling valid in all 15 European Union-Member States.

OGS submitted its marketing authorisation application to the EMEA in July 2001. Zavesca has been granted orphan medicinal product status in Europe, allowing for a ten-year marketing exclusivity period following approval. A copy of the approved English label for Zavesca can be found at ogs.com .
