Sanofi-aventis Press Release
with Cabazitaxel in Patients with Advanced - Results Demonstrated 28% Improvement in Overall Survival -

Paris, France - May 27, 2010 - Sanofi-aventis (EURONEXT: SAN and NYSE: SNY) announced today the
updated results from the Phase 3 trial, TROPIC, that demonstrated the investigational drug cabazitaxel plus
prednisone/prednisolone, significantly improved overall survival, versus an active chemotherapy combination
of mitoxantrone plus prednisone/prednisolone, in patients with metastatic hormone-refractory (castration-
resistant) prostate cancer whose disease progressed following treatment with docetaxel-based
“It is impressive to see the updated results continue to demonstrate an improvement in overall survival
compared with that achieved with a standard chemotherapy regimen,”
said Marc Cluzel, M.D., Ph.D,
Executive Vice-President, Research & Development, sanofi-aventis. “These are encouraging results in a
difficult-to-treat stage of prostate cancer.”

Updated results of the primary end point (overall survival) – to be presented at the 2010 American Society of
Clinical Oncology (ASCO) Annual Meeting on June 6 – will show that the combination of cabazitaxel and
prednisone/prednisolone significantly reduced the risk of death by 28% [HR=0.72 (95% CI: 0.61-0.84);
P<0.0001] with an improvement in the median overall survival of 15.1 months vs. 12.7 months in the
mitoxantrone combination arm.
The most frequent grade 3/4 hematological adverse events with cabazitaxel were neutropenia (81.7%)
assessed by laboratory values, leukopenia (68.2%), anemia (10.5%), and febrile neutropenia (7.5%); the
most frequent grade 3/4 non-hematological adverse events were diarrhea (6.2%), fatigue (4.9%), and
asthenia (4.6%). Discontinuation of treatment due to adverse events occurred in 18.3% of patients in the
cabazitaxel arm and 8.4% of patients in the mitoxantrone arm. Most frequent treatment-emergent adverse
events leading to discontinuation in the cabazitaxel arm were neutropenia (2.4%), hematuria (1.3%), diarrhea
(1.1%) and fatigue (1.1%). Grade 3/4 peripheral neuropathy occurred in 0.5% of patients in the cabazitaxel
arm vs. 0.3% in the mitoxantrone arm. Deaths due to adverse events were 4.9% in the cabazitaxel arm
(predominantly due to neutropenia and its complications) vs. 1.9% in the mitoxantrone arm.
“Providing solutions that have a major impact on patients with cancer, such as metastatic castration-resistant
prostate cancer, is the driving force behind everything we do,”
said Debasish Roychowdhury, M.D., Senior
Vice President, Global Oncology, sanofi-aventis. “The development of cabazitaxel is one of many
investigational compounds we hope to present to the cancer community in the months and years to come.”

The TROPIC study results were chosen by the ASCO Committee to be presented on July 16-17 and July 23-
24 at the Best of ASCO sessions in San Francisco, CA and Boston, MA; these meetings are held to provide
wider access to cutting-edge science presented at the annual meeting.

About the TROPIC Trial
TROPIC was conducted in 146 trial sites in 26 countries throughout the world, including the U.S. The multi-
center Phase 3 randomized registrational trial assessed 755 metastatic castration-resistant prostate cancer
patients whose disease had progressed following treatment with docetaxel-based chemotherapy.
The primary endpoint was overall survival. Secondary endpoints included progression-free survival, tumor
response rate, tumor progression, prostate-specific antigen (PSA) response, PSA progression, pain
response, and pain progression. Disease progression in this trial was defined as tumor progression, PSA
progression or pain progression. Other secondary endpoints were overall safety of cabazitaxel in
combination with prednisone, the pharmacokinetics of cabazitaxel and its metabolite in this patient
population, and the effect of prednisone on the pharmacokinetics of cabazitaxel. Patients were randomly
assigned to receive cabazitaxel plus prednisone/prednisolone or mitoxantrone plus prednisone/prednisolone
(378 and 377 patients, respectively). Patients were to receive either regimen for up to a maximum of 10
About Cabazitaxel
Cabazitaxel is an investigational compound that has been shown to be active in cell lines refractory to
chemotherapies. In preclinical studies, cabazitaxel has been shown to inhibit cell division and tumor cell
proliferation by binding to and stabilizing tubulin, a protein in the microtubules of cells which provides a
skeleton for maintaining cell shape.
Cabazitaxel recently received priority review from the U.S. Food and Drug Administration (FDA); review is
anticipated by Q3 2010. Filing for approval in the EU has been completed.

About Prostate Cancer
Worldwide, prostate cancer ranks third in cancer incidence and sixth in cancer mortality in men. In the U.S.,
prostate cancer remains the second most common cause of cancer death among men after lung cancer. In
2009, an estimated 192,000 new cases were anticipated in the U.S., while 27,000 men were expected to
have died from the disease.
Metastatic prostate cancer indicates that the cancer has spread, or metastasized, to the lymph nodes or
other parts of the body, mostly to the bones. Castration resistant/hormone-refractory prostate cancer means
that the cancer has continued to grow despite the suppression of male hormones that fuel the growth of
prostate cancer cells. More than 80% of all prostate cancer cases are discovered when the disease is limited
to the prostate and surrounding organs, while 10-20% of patients are diagnosed when the cancer has
already metastasized. For many patients with this stage of prostate cancer, their disease continues to
advance despite prior chemotherapy. Currently, there are few treatment options for these patients.
