NEWLY
PUBLISHED RESEARCH INDICATES THE POTENTIAL OF PHENOXODIOL TO PROTECT AGAINST
NEUROPATHY
Novogen
Limited’s subsidiary, Marshall Edwards Inc. (NASDAQ: MSHL), has made the
following announcement:
Sydney,
Australia and New Canaan, Conn., August 13 , 2007 – Results of a study published
in the current issue of BMC Neuroscience show that investigational drug
phenoxodiol, currently being developed as a therapy for late-stage,
chemo-resistant prostate, ovarian and cervical cancers, may also have the
potential to be use used in conjunction with cisplatin chemotherapy to prevent
induction of platinum-induced neuropathy.
The
new
study examined whether phenoxodiol could protect against cisplatin-induced
neurite inhibition in PC12 cells as an indication of the potential to protect
against neuropathy. In the study, the effect of phenoxodiol on
cisplatin induced neurite toxicity was assessed by measurement of neurite
outgrowth. Study results show the addition of phenoxodiol showed no cytotoxicity
at low doses and blocked the cisplatin induced neurite toxicity.
The
study
concludes that successful prophylactic treatment of cisplatin induced neuropathy
with phenoxodiol could allow more intensive and hence more effective cisplatin
therapy. Overall, given the dose and treatment limiting neuropathic
side effects of cisplatin, one of the most widely used chemotherapeutic drugs,
and the lack of any currently available prophylactic treatment or cure, the
study also concludes that phenoxodiol is a promising candidate that warrants
further testing.
"Historical
data demonstrates that phenoxodiol has the ability to overcome drug resistance
in cancer cells,” said Dr. Ann Turnley, Associate Director, Centre for
Neuroscience, University of Melbourne. “This study indicates
that phenoxodiol has the potential to protect normal cells from the toxic
effects of chemotherapy and may help in reducing some of the side
effects."
The
title
of the new research article is Phenoxodiol protects against Cisplatin
induced neurite toxicity in a PC-12 cell model– and may be downloaded at
http://www.biomedcentral.com/1471-2202/8/61.
Oral
phenoxodiol in combination with weekly carboplatin is currently being studied
in
a multi-national Phase III clinical trial called OVATURE. The OVATURE trial
is
taking place in the United States, Europe, and Australia and is designed to
demonstrate the safety and effectiveness of phenoxodiol in combination with
weekly carboplatin compared to weekly carboplatin alone for the treatment of
ovarian cancer that has become resistant or refractory to platinum therapy.
More
information about the OVATURE trial is available at
http://clinicaltrials.gov/ and type in “OVATURE” in the search
option.
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 signaling 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 tumor
cells
to undergo apoptosis in response to chemotherapy. The putative molecular target
for phenoxodiol is a tumor-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 characterized 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 (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
specializing 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 and on the Novogen group
of companies can be found at www.marshalledwardsinc.com and
