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,
