Important Progress in Treatment of Early and Late Stage Breast Cancer With Herceptin, Avastin and T-DM1

Basel, Switzerland (ots/PRNewswire)

- Roche to Present new Results That Could Offer a Better Future
to Women With Early and Very Advanced Breast Cancer, at the
CTRC-AACR San Antonio Breast Cancer Symposium
Roche (SIX: RO, ROG; OTCQX: RHHBY) announced today that new 5
year follow-up data from two pivotal studies with Herceptin(R)
(trastuzumab) in early breast cancer; key results from a study of
Avastin(R) (bevacizumab) in the second-line treatment of advanced
breast cancer and strong data on the use of trastuzumab-DM1 (T-DM1),
the first antibody-drug conjugate in development for very advanced
HER2-positive breast cancer, will all be presented during the
CTRC-AACR San Antonio Breast Cancer Symposium (SABCS) from 9 to 13
December 2009.
"Breast cancer is the most common cancer among women worldwide
with more than one million new cases diagnosed every year and nearly
400,000 deaths, so it is vital that we continue to provide more
treatment options," said William M. Burns, CEO of Roche Pharma. "The
much anticipated data on Herceptin, Avastin and the investigational
drug T-DM1 will be welcomed by physicians treating women with early
and very advanced stages of breast cancer as it will offer them more
choices for fighting this devastating disease."
Two Herceptin studies in early breast cancer, five year follow up
data (N9831, BCIRG 006)
- 5-years of follow-up data will be presented from these pivotal phase
      III studies that have already shown efficacy in patients when adding 12
      months of Herceptin to standard therapy.
    - Both studies were seeking to answer questions the medical community has
      been contemplating regarding the best way of giving their patients
      Herceptin treatment.
    Avastin RIBBON-2 study, second-line treatment data
    - Avastin is well established as a first-line treatment for women with
      advanced breast cancer. RIBBON-2 will report on the benefits of Avastin
      in combination with commonly used chemotherapies in the second-line
      setting where currently the only option is subsequent chemotherapy.
T-DM1 4374 study in very advanced breast cancer
New data from a phase II study (TDM4374) in a very advanced
patient population who have exhausted other treatment options will be
presented. This follows on from another phase II study (TDM4258) that
was presented at ASCO 2009 which showed encouraging results in women
with advanced HER2-positive breast cancer.
In addition, further data from the phase II study BO17929 will be
presented, demonstrating that the combination of pertuzumab and
trastuzumab shows efficacy in patients with HER2-positive advanced
breast cancer whose disease had progressed during prior treatment
with Herceptin plus chemotherapy.[i] The data, which suggest that
combining pertuzumab and trastuzumab may offer an effective new
treatment option to patients with HER2-positive advanced breast
cancer, have been accepted as a poster presentation on Saturday 12
Dec, 17:30 - 19:30, Poster Session 5, Exhibit Halls A-B.

In HER2-positive breast cancer, increased quantities of the HER2
protein are present on the surface of the tumour cells. This is known
as 'HER2-positivity'. High levels of HER2 are present in a
particularly aggressive form of the disease which responds poorly to
chemotherapy. Research shows that HER2-positivity affects
approximately 20-30 percent of women with breast cancer.[ii]
