2011 Highlights

Perifosine (Oral Akt Inhibitor)

• Agreement signed with Yakult Honsha Co., Ltd. (TOKYO: 2267: JP) ("Yakult") for the development and commercialization of perifosine for the Japanese territory. Aeterna Zentaris received an initial $8.4 million upfront payment, and is entitled to receive up to $57.1 million in additional payments upon achieving certain pre-established milestones, as well as double-digit royalties on future net sales of perifosine in Japan.
• Initiation by Yakult of a Phase 1/2 trial in Japan with perifosine, in refractory advanced colorectal cancer ("CRC"), triggering a milestone receivable.
• Completion of patient recruitment for the ongoing Phase 3 trial with perifosine in CRC. The Data Safety Monitoring Board recommended that the trial proceed as planned.
• Patent granted by the European Patent Office for the use of perifosine in combination with antitumor anti-metabolites, including 5-FU and capecitabine, for the treatment of benign and malignant tumors, with patent protection until July 28, 2023.
• Commercialization and licensing agreement signed with Hikma Pharmaceuticals (LSE: HIK.L) ("Hikma") for the registration and marketing of perifosine in certain countries in the Middle East and North Africa ("MENA"). Aeterna Zentaris received an upfront payment of $0.2 million and is entitled to receive additional payments upon achieving certain pre-established milestones in the aggregate of $1.8 million, as well as double-digit royalties on future net sales of perifosine in the MENA region.
• Data from a Phase 2 trial in refractory/relapsed Hodgkin's lymphoma presented at the American Society of Hematology (ASH)  meeting, demonstrated that perifosine combined with sorafenib significantly increased median progression-free survival.
• The Journal of Clinical Oncology published two articles on perifosine. The first article outlined encouraging Phase 2 data in CRC for perifosine + capecitabine while the second article outlined encouraging Phase 1/2 data in multiple myeloma for perifosine + bortezomib.

AEZS-108 (LHRH-Targeted Cytotoxic Conjugate)

• Final Phase 2 data for AEZS-108, in advanced endometrial cancer were presented at the International Meeting of the European Society of Gynecological Oncology. Parallel scientific advice process granted by and initiated with the FDA and EMA to establish a pivotal program in this indication.
• Physician's sponsored IND initiated at the Sylvester Comprehensive Cancer Center, for a Phase 2 trial in triple-negative breast cancer with AEZS-108.
• Agreement signed with Ventana Medical Systems, Inc., a member of the Roche Group, to develop a companion diagnostic for AEZS-108.

AEZS-130 (Oral Ghrelin Agonist)

• Favorable top-line results reported for Phase 3 study with AEZS-130 as first oral diagnostic test for adult growth hormone deficiency ("AGHD"). Current ongoing discussions with the FDA for NDA filing.

Corporate Developments

• The Company issued a total of 19.5 million shares under its "At-the-Market" ("ATM") sales agreements for aggregate gross proceeds of $37.5 million.
• The Company also issued a total of 1.7 million shares pursuant to the exercise of certain warrants for aggregate gross proceeds of $2.2 million.
• The Company received $2.5 million of net sales royalty milestone payment from Cowen Healthcare Royalty Partners L.P, ("Cowen") pursuant to the sale, in December 2008, of Aeterna Zentaris' royalty stream for Cetrotide^®.

Subsequent to Year-End

AEZS-108

• Results for the Phase 1 portion of the ongoing Phase 1/2 study in castration- and taxane-resistant prostate cancer demonstrated that AEZS-108 was well tolerated and demonstrated early evidence of antitumor activity.

AEZS-130

• Initiation of a Phase 2A trial with AEZS-130 in cancer-cachexia, under a CRADA with the Michael E. DeBakey VA Medical Center.

At-The-Market Issuance Program

• The Company initiated a new ATM program at the beginning of 2012, under which it raised from January 23, 2012 up to March 15, 2012 a total of $6.4 million by issuing 3.6 million shares.

Cash and cash equivalents and short-term investment totalled $46.9 million as at December 31, 2011, compared to $33.9 million as at December 31, 2010.

Juergen Engel, Ph.D., Aeterna Zentaris President and Chief Executive Officer, commented, "2011 has been marked by significant strategic achievements as we continued to move our lead products through the pipeline, secured two additional partnerships for perifosine and materially strengthened our cash position. We are now eagerly awaiting results for the Phase 3 trial of perifosine in colorectal cancer. Should results of the perifosine CRC trial prove to be conclusive, our primary focus would be to pursue NDA and MAA filings for perifosine with U.S. and European regulatory authorities. If perifosine is found to be safe and effective, it could provide a much needed novel treatment for thousands of patients afflicted with this disease, worldwide; as well, it would represent a large market opportunity for the Company.

Our other late-stage drug development priorities for this year are the patient enrollment into the Phase 3 trial with perifosine in multiple myeloma which has been expanded to several countries outside the United States over the last several months; the NDA filing for AEZS-130 as the first oral diagnostic test for AGHD; and the initiation of a registration Phase 3 trial with AEZS-108 in endometrial cancer. We also look forward to advancing earlier-stage key anticancer product candidates from our pipeline, including AEZS-112, AEZS-120 and Erk/PI3K inhibitors."

Dennis Turpin, CA, SVP and Chief Financial Officer at Aeterna Zentaris stated, "With the Company's $46.9 million cash position as at December 31, 2011, and the collaboration of our perifosine licensee partners, we are well poised to pursue our focused product pipeline development strategy."

CONSOLIDATED RESULTS AS AT AND FOR THE FOURTH QUARTER ENDED DECEMBER 31, 2011

Revenues were $12.6 million for the quarter ended December 31, 2011, compared to $10 million for the same quarter in 2010. The comparative increase in revenues is due primarily to higher deliveries of Cetrotide^® to Merck Serono and to the recording of a milestone payment from Yakult with respect to the initiation of a Phase 1/2 trial with perifosine in CRC in Japan, partly offset by the lower royalties in 2011 attributable to a contingent payment from Cowen recorded in December 2010.

R&D costs, net of refundable tax credits and grants were $7.8 million for the quarter ended December 31, 2011, compared to $5.4 million for the same quarter in 2010. The comparative increase in R&D expenses primarily results from the increase in third-party costs incurred in connection with the advancement of perifosine, AEZS-108 and Erk/PI3K compounds (AEZS-129, AEZS-131, AEZS-132)-related activities.

Selling, general and administrative ("SG&A") expenses were $5.4 million for the quarter ended December 31, 2011, compared to $3.2 million for the same quarter in 2010. The comparative increase in SG&A expenses is mainly related to the recognition of an impairment loss on property, plant and equipment as well as an additional onerous lease provision, combined with the pre-launch and marketing efforts related to the potential commercialization of perifosine in Europe, and the increase in foreign exchange loss.

Net loss amounted to $7.5 million, or $0.07 per basic and diluted share, for the quarter ended December 31, 2011, compared to $6.6 million, or $0.08 per basic and diluted share, for the same quarter in 2010. The comparative increase in net loss is mainly attributable to the higher R&D and SG&A expenses, partly offset by the significant increase in net finance income and by higher gross margin relating to sales of Cetrotide^®.

CONSOLIDATED RESULTS FOR THE FULL YEAR ENDED DECEMBER 31, 2011

Revenues were $36.1 million for the year ended December 31, 2011, compared to $27.7 million for the year ended December 31, 2010. The comparative increase in revenues is due primarily to higher deliveries of Cetrotide^® to Merck Serono and to the recording of a milestone payment from Yakult with respect to the initiation of a Phase 1/2 trial with perifosine in CRC in Japan, partly offset by the lower royalties in 2011 attributable to a contingent payment from Cowen recorded in December 2010.

R&D costs, net of refundable tax credits and grants, were $24.5 million for the year ended December 31, 2011, compared to $21.3 million for the year ended December 31, 2010. The comparative increase is mainly attributable to an increase in third-party costs incurred in connection with the advancement of perifosine, AEZS-130 and Erk/PI3K compounds (AEZS-129, AEZS-131, AEZS-132)-related activities.

Selling, general and administrative ("SG&A") expenses were $16.2 million for the year ended December 31, 2011, compared to $12.6 million for the year ended December 31, 2010. The comparative increase in SG&A expenses was mainly due to the recognition of impairment losses and to the initiation of pre-launch and marketing efforts related to the potential commercialization of perifosine in Europe.

Net loss for the year ended December 31, 2011 was $27.1 million, or $0.29 per basic and diluted share, compared to $28.5 million, or $0.38 per basic and diluted share for the year ended December 31, 2010. The comparative decrease in net loss is largely due to the significant increase in license fees revenues, as well as net finance income, partly offset by lower margin contribution from Cetrotide^®, higher net R&D costs and SG&A expenses, as well as an income tax expense recorded in 2011.
