Æterna Zentaris Announces Positive Results for Phase 2 Study with
LHRH-Receptor Targeted Cytotoxic Conjugate AEZS-108 in Endometrial Cancer
Primary efficacy endpoint has been met for patients with advanced-stage or recurrent endometrial cancer
QUÉBEC CITY,
Preliminary Results
A preliminary evaluation has shown that the study AGO-GYN 5 met its predefined primary efficacy endpoint of 5 or more responder patients with endometrial cancer. The study is currently ongoing, and responders, as well as patients with stable disease after completion of treatment with AEZS-108, will be followed to assess the duration of progression-free survival and, ultimately, overall survival. Detailed analyses of the study results will be presented at forthcoming scientific conferences.
Juergen Engel, Ph.D., President and Chief Executive Officer at Æterna Zentaris stated, "We are pleased with the progress of this Phase 2 program. Along with the recently disclosed positive results for the ovarian cancer indication, the good news for the endometrial cancer indication provides us with an even stronger basis to take the next steps in the development of AEZS-108 in gynaecological cancers."
About AEZS-108 and its Phase 2 program
AEZS-108 represents a new targeting concept in oncology using a cytotoxic peptide conjugate which is a hybrid molecule composed of a synthetic peptide carrier and a well-known cytotoxic agent, doxorubicin. The design of this product allows for the specific binding and selective uptake of the cytotoxic conjugate by LHRH-receptor positive tumors. The binding of AEZS-108 to cancerous cells that express these receptors, results in its accumulation and preferential uptake in the malignant tissue.
In a Phase 2 study program entitled, "The antitumoral activity and safety of AEZS-108 (AN-152), a LHRH agonist linked doxorubicin in women with LHRH-receptor positive gynaecological tumors", patients with tumors expressing LHRH receptors are administered an intravenous infusion of 267 mg/m2 of AEZS-108 over a period of 2 hours, every Day 1 of a 21-day (3-week) cycle. The proposed duration of the study treatment is 6, 3-week cycles.
Study AGO-GYN 5 is performed with 14 centers of the German Gynaecological Oncology Working Group (AGO; www.ago-ovar.de), in cooperation with 3 clinical sites in
The program was planned to include up to 82 evaluable patients, up to 41 with a diagnosis of platinum-resistant and taxane-pretreated ovarian cancer, (for which positive results were disclosed on
About Endometrial and Ovarian Cancer
Cancer of the endometrium is the most common gynaecologic malignancy and accounts for 6% of all cancers in women. The majority of the cases occur in postmenopausal women, with the largest number of women developing their cancers during their sixth decade. Approximately 38,000 new cases and 9,000 deaths from this disease are estimated annually in
Ovarian cancer is one of the most common gynaecologic malignancies and the fifth most frequent cause of cancer death in women, with most of the cases occurring in women between 50 and 75 years of age. Overall, ovarian cancer accounts for 4% of all cancer diagnoses in women and 5% of all cancer deaths. Approximately 26,000 new cases and 17,000 deaths from this disease are estimated in the European community every year (Source: Gynaecologic Oncology 2004; 92:819-26).
