All amounts are in U.S. dollars (except for share data).

QUEBEC CITY, Aug. 10, 2011 /PRNewswire/ - Aeterna Zentaris Inc. (NASDAQ: AEZS) (TSX: AEZ) (the “Company”), a late-stage drug development company specialized in oncology and endocrine therapy, today reported financial and operating results for the quarter ended June 30, 2011.

Second Quarter 2011 Highlights

Perifosine

  • April 4, 2011: The Company announced that two posters on perifosine were presented at the 102nd annual meeting of the American Association for Cancer Research (“AACR”) held in Orlando, Florida. The first poster illustrated perifosine’s antitumor activity in a variety of gastric cell lines, and also enhanced the antitumor activity of 5-FU in parts of the cell lines - including 5-FU resistant cell lines. The second poster demonstrated that perifosine markedly enhanced the antitumor activity of the cellular TRAIL-based treatment and was able to overcome TRAIL resistance both in vitro and in vivo.
  • Subsequent to quarter-end, on July 26, 2011, the Company announced the completion of patient recruitment for the ongoing Phase 3 trial with perifosine in refractory advanced colorectal cancer. The trial, involving over 430 patients, is being conducted pursuant to a Special Protocol Assessment (“SPA”) with the Food and Drug Administration (“FDA”) and with Fast Track designation.
  • Subsequent to quarter-end, on July 12, 2011, the European Patent Office granted a patent for the use of alkyl phosphocholines, and, more specifically for perifosine, in the preparation of a medicament for the treatment of benign and malignant tumors, prior to and/or during the treatment with approved antitumor antimetabolites including 5-FU (“fluorouracil”) and capecitabine. This patent will expire on July 28, 2023.

AEZS-108

  • Parallel Scientific Advice process granted by and initiated with the FDA and EMA, with the aim to have the pivotal program in endometrial cancer defined by year-end.
  • Progression of ongoing Phase 1/2 studies in castration refractory prostate cancer and in refractory bladder cancer.

AEZS-130

  • Subsequent to quarter-end, on July 27, 2011, the Company announced the completion of the Phase 3 trial with AEZS-130 as an oral diagnostic test for Adult Growth Hormone Deficiency (“AGHD”). The preliminary Phase 3 results were encouraging and the Company expects to file a New Drug Application (“NDA”).

AEZS-120

  • Subsequent to quarter-end, on July 20, 2011, the Company announced that it had reached a key milestone in the non-clinical development of its live recombinant prostate cancer vaccine candidate, AEZS-120, for oral administration. The program, partially funded through a grant from the German government, encompassed the full development of a GMP process, including GMP production and quality testing of a clinical batch, as well as a non-clinical safety and toxicology package, as previously agreed with regulatory authorities. Subject to a positive review by German regulatory authorities, the Company aims to start Phase 1 clinical development in 2012.

AEZS-131

  • April 5, 2011: The Company announced that a poster on AEZS-131 was presented at the 102nd annual meeting of the AACR. The poster showed AEZS-131 to be a highly selective Erk 1/2 inhibitor oral anticancer compound with in vivo antitumor potency. In in vivo mouse xenograft experiments utilizing the HCT-116 colon cancer model, AEZS-131 significantly inhibited tumor growth and was well tolerated at daily doses up to 120 mg/kg.

Corporate Developments

  • During the quarter, the Company completed the drawdowns remaining under the At-the-Market (“ATM”) Sales Agreement entered into in February 2011. During the quarter, the Company raised a total of $14.7 million in gross proceeds, bringing the total aggregate gross proceeds raised under this ATM Sales Agreement, on a year-to-date basis, to $19.7 million.
  • June 29, 2011: The Company entered into an additional ATM Sales Agreement under which, during the 24-month term of the agreement, the Company could sell up to a maximum of 9.5 million of its common shares through ATM issuances on the NASDAQ Stock Market for aggregate gross proceeds not to exceed $24.0 million. Subsequent to quarter-end and pursuant to this ATM agreement, the Company issued a total of approximately 1.9 million common shares for aggregate gross proceeds of $4.3 million, less cash and non-cash transaction costs totalling $0.3 million.

Cash, cash equivalents and short-term investment totalled $49.6 million as at June 30, 2011. With the aforementioned ATM drawdowns that were completed subsequent to quarter-end, the Company’s pro forma cash, cash equivalents and short-term investment at June 30, 2011 would total $53.8 million.

Juergen Engel, Ph.D., Aeterna Zentaris’ President and Chief Executive Officer, commented, “This quarter was marked by key drug development milestones. The patient recruitment of over 430 patients was completed for the ongoing Phase 3 trial in advanced refractory colorectal cancer with perifosine. Furthermore, we were granted a European use patent for perifosine, which will expire in July 2023. We also successfully completed our Phase 3 trial with AEZS-130 as an oral diagnostic test for Adult Growth Hormone Deficiency, and we are undertaking the necessary steps leading to a New Drug Application filing in the United States. In addition, we reached a key non-clinical milestone in the development of our live oral recombinant prostate cancer vaccine candidate, AEZS-120, and are now planning to start its clinical development.”

Dennis Turpin, CA, Senior Vice President, Chief Financial Officer of Aeterna Zentaris stated, “We now benefit from over $49.6 million in cash, cash equivalents and short-term investment and have gained additional flexibility to advance our key projects through our most recent At-the-Market Sales agreement.”

CONSOLIDATED RESULTS AS AT AND FOR THE SECOND QUARTER ENDED JUNE 30, 2011

Revenues were $6.5 million for the three-month period ended June 30, 2011, as compared to $5.6 million for the same period in 2010. This increase is largely related to comparative higher-than-normal deliveries of Cetrotide® to certain customers, as well as to the comparative strengthening of the euro against the US dollar.

Research and development costs, net of tax credits and grants were $5.6 million for the three-month period ended June 30, 2011, as compared to $5.4 million for the same period in 2010.

Selling, general and administrative expenses were $3.4 million for the three-month period ended June 30, 2011 as compared to $3.7 million for the same period in 2010.

Net finance (costs) income are comprised predominantly of net foreign exchange gains and losses, the change in fair value of the Company’s warrant liability and the unrealized gain on the Company’s short-term investment (2011 only). For the three-month period ended June 30, 2011, net finance costs totalled $2.6 million, as compared to a net finance income of $1.8 million for the same period in 2010. This significant increase in net finance costs is due to the change in fair value of the Company’s warrant liability. That change results from the periodic “mark-to-market” revaluation of currently outstanding share purchase warrants. Additionally, the increase is due to higher foreign exchange losses, which in turn resulted primarily from the comparative weakening of the US dollar against the euro during the second quarter of 2011, partially offset by the unrealized gains on the Company’s short-term investment, which is carried at fair value. Neither the loss resulting from the periodic mark-to-market valuation of the warrants nor the gain resulting from the fair value adjustments to the short-term investment has resulted in any cash disbursement or cash receipt during the three-month period ended June 30, 2011.

Net loss for the three-month period ended June 30, 2011was $10.6 million, or $0.12 per basic and diluted share, as compared to $6.2 million, or $0.08 per basic and diluted share, for the same period in 2010. This increase is mainly related to higher net finance costs related to the periodic mark-to-market valuation of the warrants (non-cash) and higher foreign exchange losses, partly compensated by the unrealized gains on the Company’s short-term investment (non-cash).
