TAXOTERE® RECEIVES POSITIVE OPINION
TAXOTERE® RECEIVES POSITIVE OPINION
FROM THE COMMITTEE FOR MEDICINAL PRODUCTS FOR HUMAN USE RECOMMENDING APPROVAL IN THE EUROPEAN UNION
FOR METASTATIC STOMACH CANCER
TAXOTERE® demonstrates a 23% reduction in the risk of mortality,
offering new hope of long-term survival for patients with advanced stomach cancer
Paris, France March 24, 2006 Sanofi-aventis announced today that the Committee for Medicinal
Products for Human Use (CHMP) of the European Medicines Agency has issued a positive opinion
recommending approval in Europe of TAXOTERE® (docetaxel) Injection Concentrate in combination
with cisplatin and 5-fluorouracil for the treatment of patients with metastatic stomach cancer,
including the cancer of the gastro esophageal (GE) junction, who have not received prior
chemotherapy for their metastatic disease. This is the first CHMP positive opinion for the treatment of
advanced stomach cancer demonstrating a survival advantage in more than a decade, thereby offering
physicians and their patients an important new option for treating a disease that is the second leading
cause of cancer death worldwide.
The U.S. Food and Drug Administration (FDA) has already approved this supplemental indication on
March 23, 2006.
The CHMP based its decision on results from the Tax 325 study, the largest international phase III
clinical trial in previously untreated advanced stomach cancer involving 445 patients.
Patients treated
with the TAXOTERE®-based chemotherapy regimen (TAXOTERE® plus cisplatin and 5-fluorouracil,
TCF) experienced a significant 23 percent reduction in the risk of death compared to patients who
received a current standard treatment of cisplatin and 5-fluorouracil (CF), (median follow-up: 23
months). The median overall survival was significantly longer with the TAXOTERE®-containing
regimen (9.2 vs 8.6 months, p=less than 0.02) with a hazard ratio of 1.29 (95% CI: 1.04-1.61). Time to disease
progression was nearly two months longer in the TAXOTERE®-containing arm (5.6 vs 3.7 months,
p=0.0004), hazard ratio 1.47 (CF/TCF 95% CI/ 1.19 -1.83).
This additional indication for a TAXOTERE®-based regimen, will represent a new reference
treatment for metastatic gastric cancer patients in this very difficult disease, said Professor Eric Van
Cutsen from the University Hospital of Gasthuisberg, Leuven, Belgium, principal European
investigator of the TAX325 trial
With an optimal treatment option and appropriate risk management
of this TAXOTERE®-based regimen, physicians will now have a more effective therapeutic strategy
for their patients
Approval from the European Commission for the use of a TAXOTERE®-based regimen in the
treatment of patients with metastatic gastric cancer would mark the eighth indication in Europe for
TAXOTERE®, which is already approved in combination with other agents for the treatment of some
of the most common cancers, including locally advanced and adjuvant breast cancer, unresectable
locally advanced or metastatic non-small cell lung cancer (NSCLC), and androgen-independent
(hormone-refractory) metastatic prostate cancer.
About the TAX 325 Study
Locally advanced or metastatic stomach cancer has a poor prognosis with a low long-term survival of
only 11.5 percent. This study was undertaken to evaluate the benefits of adding TAXOTERE® to a
standard chemotherapy regimen. The primary study endpoint was time to tumour progression (TTP),
which was significantly improved with TAXOTERE® based therapy (5.6 months) compared to
standard treatment (3.7 months) with a 32 percent reduction in the risk of progression (log-rank test
p=0.0004). The main secondary endpoint was to detect a statistically significant increase in overall
survival. Other secondary objectives included response rate, time to treatment failure, duration of
response, safety profiles, qua lity of life and disease related symptoms.
In total, 81.4 percent of the patients experienced at least one Grade 3-4 (severe) side effect with the
TAXOTERE®- based regimen versus 75.4 percent in the control arm with neutropenia being the most
common Grade 3-4 side effect in the TAXOTERE®- based regimen. The most common (all grade)
side effects associated with the TAXOTERE®- based regimen were anemia, neutropenia, diarrhea, and
nausea. The most common (all grade) side effects associated with the cisplatin and 5- fluorouracil arm
were anemia, neutropenia, nausea and vomiting. Primary prophylactic use of growth factor support
(granulocyte-colony stimulating factor, G-CSF) was not allowed per the study protocol. G-CSF is a
bone marrow growth factor that may be administered to reduce febrile neutropenia in patients
receiving myelosuppressive chemotherapy. In the TAXOTERE® arm, febrile neutropenia and/or
neutropenic infection occurred in 12 percent of patients receiving secondary prophylactic
G-CSF compared to 28 percent who did not, which represents a 57 percent reduction.
These results were last presented at the American Society of Clinical Oncology (ASCO) annual
meeting in 2005.
With this new indication, TAXOTERE® is now approved for eight indications in the
United States and Europe in four different tumour types:
In Breast Cancer:
· In the United States and in Europe TAXOTERE®, is approved for the treatment of patients
with locally advanced or metastatic breast cancer after failure of prior chemotherapy,
· TAXOTERE® is also approved in Europe in combination with doxorubicin for patients who
have received prior cytotoxic therapy for this condition and in combination with capecitabine
after failure of cytotoxic therapy which would have included anthracycline,
· In Europe, TAXOTERE® is approved in combination with trastuzumab for the treatment of
patients with metastatic breast cancer- over expressing Her2 receptor.
· In the adjuvant setting (post surgery) TAXOTERE® is approved in the U.S. and in Europe in
combination with doxorubicin and cyclophosphamide (TAC regimen) for the treatment of
patients with operable, node-positive breast cancer.
In Lung Cancer:
· In the U.S. and in Europe, TAXOTERE®, in combination with cisplatin, is approved for the
treatment of patients with unresectable locally advanced or metastatic
non-small cell lung cancer (NSCLC) who have not received prior chemotherapy,
· TAXOTERE® is also approved, as a single agent, for patients with unresectable locally
advanced or metastatic NSCLC after failure of prior platinum-based chemotherapy.
In Prostate cancer:
· TAXOTERE® is approved for use in combination with prednisone as a treatment for androgenindependent
(hormone-refractory) metastatic prostate cancer in the U.S. and in Europe
About Stomach Cancer
Stomach cancer is the 4th most common type of cancer worldwide with more than 934,000 new
patients every year. It is also the second most common cause of cancer death worldwide; with more
than 700,000 deaths annually. There were about 22,800 new cases of stomach cancer in the
United States in 2005. In Europe, this number is over 143,000 patients. At diagnosis, most patients
with stomach cancer have advanced disease with an expected
two-year survival of only 11.5 percent.
