About AEZS-108

AEZS-108 (zoptarelin doxorubicin) 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 a clinical study 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 endometrial and ovarian cancer, and is also in Phase 1/2 trials in prostate and bladder cancer. AEZS-108 has been granted orphan-drug designation by the FDA and orphan medicinal product designation from the EMA for the treatment of ovarian cancer. Aeterna Zentaris owns the worldwide rights to AEZS-108.
