Roche's Tarceva(R) Delivers Longer Life for Lung Cancer Patients

Seoul, Korea (ots/PRNewswire) - Patients worldwide with advanced
lung cancer can expect longer survival according to new data from
the TRUST study presented at the 12th World Conference on Lung
Cancer (WCLC) in Seoul, Korea. These new worldwide observations show
that patients suffering from non-small cell lung cancer (NSCLC) and
treated with Tarceva (erlotinib) in routine clinical practice are
experiencing longer life. The results from TRUST reinforce the
benefits that patients experienced in the landmark BR.21 study that
earned Tarceva its approval in over 80 countries. Non-small cell
lung cancer is the most common form of lung cancer suffered by over
one million people worldwide.

In BR.21, 31% of patients receiving Tarceva were alive at one year
compared to 22% in the placebo arm and patients experienced a 42.5%
improvement (6.7 months vs. 4.7 months) in length of survival. In
TRUST, data from 6,181 patients reported a median overall survival
of 7.5 months. Data on the remaining patients are still being
analyzed and will be announced at a later date.

"The increased survival time in patients from TRUST reinforces
what we are seeing in our clinical practices," said Professor Tony
Mok of the Department of Clinical Oncology, Chinese University of
Hong Kong. "These new data further underscore the drug's potential
across a broad range of lung cancer patients and show that Tarceva
enables patients to spend more quality time with their families and
loved ones."

TRUST is the largest and longest ongoing study ever conducted of
Tarceva. It includes almost 12,000 patients with advanced NSCLC in
over 59 countries in Asia, Europe and the Americas.

Over 182,000 patients worldwide have been treated with Tarceva
since it was launched three years ago. These latest data reinforce
that Tarceva is fulfilling its promise of offering longer survival
and better quality of life to a broad range of patients - men, women,
smokers, non-smokers and people from a wide range of ethnic groups -
with NSCLC, one of the world's most deadly forms of cancer.

"TRUST demonstrates that even in routine clinical practice Tarceva
has comparable efficacy to BR.21," said Dr. Ulrich Gatzemeier, an
investigator for TRUST at the Department of Thoracic Oncology,
Hospital Grosshansdorf, Hamburg, Germany. "This is a great step
forward in the treatment of lung cancer, and one which will offer
hope to many patients and families affected by this disease."

Roche's ongoing commitment to patients

Tarceva is currently being evaluated in an extensive clinical
development program on earlier stages of NSCLC by a global alliance
comprising OSI Pharmaceuticals, Genentech and Roche. Under this
program, almost 20 clinical studies are being conducted with Tarceva
to discover new ways to further increase its life-extending benefits
for patients with lung and other types of cancer. Additionally,
Tarceva is being studied in combination with Avastin in NSCLC and in
a wide variety of other solid tumour types.

"TRUST is just one of the many major clinical trials supported by
Roche currently underway to help identify those patients who can
benefit the most from treatment with Tarceva," said William M. Burns,
CEO of the Pharmaceuticals Division at Roche. "Our focus is to
improve survival rates and quality of life for people suffering from
all types of cancer."

Notes to Editors

About TRUST

TRUST, the largest and longest ongoing study of Tarceva in lung
cancer worldwide, involves nearly 12,000 NSCLC patients from 59
countries across Asia, the Middle East, Europe and the Americas. It
is a multi-center, global, open-label study of Tarceva in lung cancer
patients for the second- or third-line treatment of advanced
non-small cell lung cancer (NSCLC). Also an expanded access program,
TRUST enabled thousands of patients worldwide with advanced NSCLC to
receive early access to Tarceva by filling the gap between the
submission date of the new drug application and the date of final
approval. Since TRUST started in 2004, 93% of the participating
countries received approval of Tarceva as monotherapy for patients
with advanced NSCLC.

About BR.21

EU approval for Tarceva was based on a pivotal Phase III study -
BR.21 - published in the New England Journal of Medicine. BR.21 was
conducted by the National Cancer Institute of Canada Clinical Trials
Group, in collaboration with OSI Pharmaceuticals, with the
participation of 86 sites from 17 countries around the world. This
study involved 731 patients with advanced NSCLC whose cancers had
progressed after first- or second-line chemotherapy and compared
patients receiving Tarceva monotherapy with placebo.

The key study results were:

- Treatment with Tarceva in patients with advanced NSCLC resulted
in significantly longer survival compared to placebo, a 42.5%
improvement (6.7 months vs. 4.7 months).

- 31% of patients receiving Tarceva were alive at one year
compared to 22% in the placebo arm.

- Patients receiving Tarceva had stability or control of their
lung cancer-related symptoms such as cough, shortness of breath and
pain, for significantly longer.

- Patients also had a superior quality of life and improved
physical function compared to those on placebo.

- The benefits of Tarceva were shown in a broad spectrum of
patients.

About Tarceva

Tarceva is the first and only EGFR oral targeted agent with proven
and significant survival and symptom benefit in a broad range of
patients with advanced lung and pancreatic cancer. Currently most
lung and pancreatic cancer patients are treated wholly with
chemotherapy which can be very debilitating due to its toxic nature.
Tarceva works differently to chemotherapy by specifically targeting
tumour cells, and avoids the typical side-effects of chemotherapy.

Tarceva has been approved in the European Union since September
2005 and in the US since November 2004 for the treatment of patients
with locally advanced or metastatic NSCLC after failure of at least
one prior chemotherapy regimen. Furthermore, Tarceva, in combination
with chemotherapy, is the first treatment in over a decade to have
shown a significant survival benefit in treating patients with
pancreatic cancer. It is approved in the US, in combination with
gemcitabine, for the first-line treatment of patients with locally
advanced, unresectable or metastatic pancreatic cancer and in the EU
for treatment of metastatic pancreatic cancer. Since its initial
launch three years ago, Tarceva has been used to treat more than
182,000 patients and has been approved in over 80 countries
worldwide.

Roche in Oncology

The Roche Group, including its members Genentech in the United
States and Chugai in Japan, is the world's leading provider of cancer
care products, including anti-cancer treatments, supportive care
products and diagnostics. Its oncology business includes an
unprecedented five products proven to provide survival benefit in
different major tumour indications: Avastin, Herceptin, and Xeloda in
advanced-stage breast cancer, Herceptin in early-stage HER2-positive
breast cancer, MabThera in non-Hodgkin's lymphoma, Avastin and Xeloda
in colorectal cancer, Avastin and Tarceva in non-small cell lung
cancer and Tarceva in pancreatic cancer (1).

In addition to these anti-cancer agents, the Roche oncology
portfolio includes a comprehensive collection of medicines that can
help improve the quality of life of cancer patients: Bondronat (for
prevention of skeletal events in patients with breast cancer and bone
metastases, hypercalcaemia of malignancy), Kytril (for chemotherapy
and radiotherapy-induced nausea and vomiting), Neupogen (for
cancer-related neutropenia), and NeoRecormon (for anaemia in various
cancer settings). CERA is the most recent demonstration of Roche's
commitment to anaemia management. Other oncology products include
Furtulon (for colorectal cancer) and Roferon-A (for hairy cell and
chronic myeloid leukaemia, Kaposi's sarcoma, malignant melanoma,
renal cell carcinoma). The Roche Group's cancer medicines generated
sales of more than 7.7 billion Swiss francs in 2004.

In addition to the medicines, Roche is developing new diagnostic
tests that will have a significant impact on disease management for
cancer patients in the future. With a broad portfolio of tumour
markers for prostate, colorectal, liver, ovarian, breast, stomach,
pancreas and lung cancer, as well as a range of molecular oncology
tests, Roche will continue to be the leader in providing
cancer-focused treatments and diagnostics.

The unmatched Roche oncology portfolio as well as an extensive
external innovation base through collaborations with companies and
academia is what makes it possible for Roche to provide more
effective cancer therapies.

In the United States, Herceptin, MabThera (Rituxan), Avastin and
Tarceva are marketed either by Genentech alone or together with its
partners Biogen Idec Inc. (MabThera) and OSI (Tarceva). Outside of
the United States, Roche and its Japanese partner Chugai are
responsible for the marketing of these medicines.
