MEDIA RELEASE


Attention National and Sydney-based health writers 


New breast cancer treatment improves survival time 

and reduces treatment side effects


A new nanoparticle chemotherapy listed on the Pharmaceutical Benefits Scheme shows

longer survival than a commonly used chemotherapy treatment in women with metastatic

breast cancer


Thursday 14 May 2009: A new treatment option for Australian women with metastatic breast cancer which

improves survival time and reduces the side effects of common chemotherapy treatment is set to be widely

available to Australian women now that is has been listed on the Pharmaceutical Benefits Scheme.


The new treatment is called Abraxane

®

(nanoparticle albumin-bound paclitaxel) and it is approved for the

treatment of metastatic carcinoma of the breast after the failure of anthracycline therapy (ie, chemotherapy)¹.


The published studies on which approval has been based describe Abraxane as “an important advance in the

treatment of metastatic breast cancer”². A study comparing Abraxane to solvent-based paclitaxel showed

women treated with Abraxane had superior overall efficacy, with significantly higher response rates, longer

time to disease progression and longer overall survival in pre-treated patients ¹

Abraxane is the first solvent-free taxane available to women with metastatic breast cancer as a treatment

option, therefore eliminating solvent-induced toxicities such as severe hypersensitivity reactions and fatal

anaphylaxis

Over 100 Australian patients have already been treated with Abraxane free of charge following the launch of a

company-sponsored “Abraxane Patient Access Program” (APAP) which began in February 2009. 


Australian medical oncologist Associate Professor Fran Boyle from the Mater Hospital in Sydney said that

new, more effective options are always welcomed by oncology specialists in Australia.


“Many women have problems tolerating some existing chemotherapies, due to the corticosteroids required to

minimise severe hypersensitivity reactions so it is a pleasing addition to the oncologists’ drug armamentarium,”

said Associate Professor Boyle. “However, women who are currently deriving benefit from their existing

chemotherapy should not change their therapy. They should discuss this new treatment option with their

oncologist”.


Leading Queensland oncologist Associate Professor Paul Mainwaring from The Mater Hospital in Brisbane

said he was pleased to see that the regulators had moved promptly to list Abraxane on the Australian PBS.


“Abraxane has provided a much-needed new treatment option for women with metastatic breast cancer in the

USA.  Abraxane has become the taxane therapy of choice for oncologists in the US in this setting so it’s good

news that we can now have the option of using it with our patients here in Australia”, said A/Prof Mainwaring.


International oncologist Professor Hope Rugo from the University of California, San Francisco, says the

treatment is a welcome addition to the current range of breast cancer treatments available to Australian

women.


“The key to better treatment is finding therapies that delay the advance of the tumour, improve patient survival

outcomes and, in the case of those chemotherapies that require pre-medication with corticosteroids, reducing

corticosteroid and solvent-related side effects. The published clinical data and clinical experience in the US

suggests Abraxane is going to satisfy those criteria,” said Professor Rugo.

About ABRAXANE

®

ABRAXANE is a solvent-free, nanoparticle chemotherapy treatment option for metastatic breast cancer.

Developed using Abraxis BioScience's proprietary nab technology platform, ABRAXANE is a nanoparticle

protein-bound chemotherapy agent, which combines paclitaxel with albumin, a naturally-occurring human

protein, to deliver the drug and eliminate the need for solvents in the administration process. Nanoparticle

technology allows ABRAXANE to deliver a 49% higher dose compared to regular solvent-based paclitaxel

(Taxol

®

) without compromising safety and tolerability. In a previous randomized Phase III study of metastatic

breast cancer patients, ABRAXANE demonstrated nearly double the overall tumor response rate compared to

solvent-based paclitaxel and anthracycline pre-treated patients lived significantly longer

4

.  

ABRAXANE is currently under Phase III investigation for the treatment of the following cancers: first-line

metastatic breast, non-small cell lung, malignant melanoma, and metastatic pancreatic.

Abraxane is now approved in over 35 countries including the U.S., Canada, European Union and China, and

more than 45,000 cancer patients have received Abraxane therapy in the past three years.
