FIRST
PATIENT ENROLLED IN EUROPE IN OVATURE PHASE III OVARIAN CANCER
TRIAL
Novogen
Limited’s subsidiary, Marshall Edwards Inc. (NASDAQ: MSHL), has made the
following announcement:
Sydney,
Australia and New Canaan, Con, August 27, 2007 - Marshall Edwards,
Inc. (Nasdaq : MSHL) today announced enrolment of the first patient
in Europe in the Phase III Ovature clinical trial of phenoxodiol in women with
advanced ovarian cancer resistant or refractory to platinum-based
drugs.
The
first
patient to commence on the study at an Ovature site in the EU has been enrolled
at the Catholic University of Leuven, Belgium, under the direction of Professor
Ignace Vergote, Head of Gynaecologic Oncology.
“We
are
hopeful that a positive outcome of this multi-centre study will be a significant
medical advance for thousands of women with late stage ovarian cancer whose
tumours have become insensitive to the existing chemotherapeutic drugs,”
Professor Vergote said.
“As
one
of Europe’s largest cancer institutions, it is important for us to be a part of
these worldwide studies. It is important that we continue to develop
new ovarian cancer treatments. It is only through constant research
that we will learn how to battle this deadly disease effectively,” said
Professor Vergote.
The
Catholic University of Leuven is one of 26 sites in UK and Europe which will
be
recruiting patients into this major multi-centre multinational ovarian cancer
study to determine the safety and effectiveness of the drug phenoxodiol, when
used in combination with the chemotherapy drug, carboplatin. Ovarian cancer
patients whose cancer initially responded to chemotherapy, but has since become
resistant or refractory to traditional platinum treatments are eligible to
participate.
There
will be an additional 30 sites in the USA, of which 7 are now recruiting
patients, and there are 4 sites open in Australia.
The
total
number of patients to be treated in this pivotal study is 470. The
trial consists of two double blind treatment arms. Patients in one
trial arm will receive weekly carboplatin and phenoxodiol. Patients
in the other trial arm will also receive weekly carboplatin, but a placebo
will
be substituted for phenoxodiol. Neither patients, nor their doctors
will know to which trial arm the patients are randomised.
A
change
from receiving carboplatin (or cisplatin) in the traditional dose pattern (every
two to three weeks) to a weekly carboplatin regimen has been reported to provide
a tumour response in some patients with recurrent ovarian cancer1-3. Thus
in addition to learning more about the safety and efficacy of phenoxodiol,
researchers will learn more about the efficacy of weekly
carboplatin.
The
primary outcome of the trial is the assessment of the relative time it takes
for
the ovarian cancer to progress. An analysis of interim results will be possible
after 95 patients have progressed with their disease.
The
trial
is being run under arrangements approved by the US Food and Drug Administration
(FDA) known as a Special Protocol Assessment (SPA). This provides for the
interim analysis of the data, which, if significant, can be used to support
a
request for grant of marketing approval.
The
Chief
Executive Officer of Marshall Edwards, Inc., Mr. Christopher Naughton, said
the
Phase III Ovature study was a significant milestone for the
Company.
“Over
the
next 12 to 18 months we expect the interim results from this multi-national
clinical trial which may lead to the first approval for phenoxodiol,” Mr.
Naughton said.
In
a
prior Phase II clinical trial, phenoxodiol was tested in combination with either
cisplatin or paclitaxel. Patients with late stage ovarian cancer that
had become refractory to platinum or paclitaxel therapy, following multiple
courses of chemotherapy, were treated with phenoxodiol and cisplatin or
phenoxodiol and paclitaxel, respectively. Of 21 patients in the
cisplatin arm there were six partial responders, nine patients with stabilised
disease and six patients who had disease progression; of 19 in the paclitaxel
arm, there was one complete responder, two partial responders, eleven with
stabilised disease and five patients who had disease
progression. There were few side effects associated with phenoxodiol,
but, as with any investigational drug, there is a possibility of unexpected
side
effects.
Professor
Ignace Vergote, the Principal Investigator at the Leuven site was Chairman
of
the EORTC Gynaecologic Cancer Group from 1997 to 2003, and still chairs the
Protocol Committee of that group. He is currently the President of the
International Cancer Society and Immediate Past-President of the European
Society of Gynaecologic Oncology.

About
phenoxodiol: Phenoxodiol is being developed as a therapy for
late-stage, chemo-resistant prostate, ovarian and cervical
cancers. Phenoxodiol is an investigational drug and, as such, is not
commercially available. It is a novel-acting drug that inhibits key
pro-survival signalling pathways operating via sphingosine-1-phosphate and
Akt. Inhibition of these pathways leads to prevention of
phosphorylation of key anti-apoptotic proteins such as XIAP. Loss of activity
of
these proteins restores the ability of chemoresistant tumour cells to undergo
apoptosis in response to chemotherapy. The putative molecular target
for phenoxodiol is a tumour-specific protein, accounting for the highly
selective nature of the drug.
About
Marshall Edwards, Inc. : Marshall Edwards, Inc. (Nasdaq: MSHL) is a
specialist oncology company focused on the clinical development of novel
anti-cancer therapeutics. These derive from a flavonoid technology
platform which has generated a number of novel compounds characterised by broad
ranging efficacy against a range of cancer targets with few side
effects. The unique combination of efficacy and safety has been
explained by their ability to target an enzyme present on the surface of cancer
cells, thereby inhibiting the production of pro-survival proteins within the
cell. Marshall Edwards, Inc., has licensed rights from Novogen
Limited (ASX: Novogen - Nasdaq: NVGN) to bring three oncology drugs -
phenoxodiol, NV-196 and NV-143 - to market globally. Marshall
Edwards, Inc., is majority owned by Novogen, an Australian biotechnology company
that is specialising in the development of therapeutics based on a flavonoid
technology platform. Novogen, based in Sydney, Australia, is
developing a range of therapeutics across the fields of oncology, cardiovascular
disease and inflammatory diseases. More information on phenoxodiol
