About AEZS-108 (doxorubicin peptide conjugate)

AEZS-108 represents a new targeting concept in oncology using a hybrid
molecule composed of a synthetic peptide carrier and a well-known
chemotherapy agent, doxorubicin. AEZS-108 is the first intravenous drug
in advanced clinical development that directs the chemotherapy agent
specifically to LHRH-receptor expressing tumors, resulting in more
targeted treatment with less damage to healthy tissue. The product has
successfully completed Phase 2 studies for the treatment of ovarian and
endometrial cancer and the Company is currently planning a Phase 3
trial in endometrial cancer under a Special Protocol Assessment.
AEZS-108 is also in Phase 2 trials in triple-negative breast cancer,
prostate cancer and bladder cancer. AEZS-108 has been granted orphan
drug designation by the FDA and orphan medicinal product designation
from the European Medicines Agency for the treatment of ovarian cancer.
Aeterna Zentaris owns the worldwide rights to AEZS-108.

About Endometrial Cancer

Endometrial cancer is the most common gynecologic malignancy and
develops when abnormal cells amass to form a tumor in the lining of the
uterus. It largely affects women over the age of 50 with a higher
prevalence in Caucasians and a higher mortality rate among African
Americans. Approximately one in 30 women is diagnosed with endometrial
cancer every year. According to the American Cancer Society, an
