QUEBEC CITY, Nov. 13, 2012 /PRNewswire/ - Aeterna Zentaris Inc. (NASDAQ: AEZS) (TSX: AEZ) (the "Company"), an oncology and endocrinology drug development company currently investigating treatments for various unmet medical needs, today reported financial and operating results for the third quarter ended September 30, 2012.

Highlights

Perifosine (Oral Akt Inhibitor)

• The Company increased its focus on patient recruitment for the ongoing Phase 3 trial in multiple myeloma ("MM") by opening additional sites in Europe. Pre-planned interim analysis by an independent Data Safety Monitoring Board ("DSMB") expected upon reaching approximately 80 events (disease progression or death).
• The Company's partner for the Japanese market, Yakult Honsha Co. Ltd. ("Yakult"), made progress with the Phase 1 bridging study in MM initiated earlier this year and is also looking to expand work with perifosine in other indications.

AEZS-108 (Cytotoxic Peptide Conjugate Linked to Doxorubicin)

• Subsequent to quarter-end, a Special Protocol Assessment ("SPA") was filed with the Food and Drug Administration ("FDA") with the goal of initiating a Phase 3 trial in endometrial cancer during the first quarter of 2013.

AEZS-130 (Oral Ghrelin Agonist)

• Fast Track designation not granted to AEZS-130 as oral diagnostic test for adult growth hormone deficiency ("AGHD"). The Company continues to expect to file New Drug Application ("NDA") during the first quarter of 2013.
• Subsequent to quarter-end, Phase 3 trial results presented at the International Congress of GRS and IGF Society demonstrated AEZS-130 to be safe and effective in diagnosing AGHD.
• First patient recruited for Phase 2A trial of AEZS-130 in cancer-induced cachexia. Study conducted under a Cooperative Research and Development Agreement ("CRADA") between the Company and the Michael E. DeBakey Veterans Affairs Medical Center which is funding the study.

Corporate Developments

Share Consolidation and NASDAQ Minimum Bid Price Compliance

• Subsequent to quarter-end, the Company's common shares were consolidated on a 6-to-1 basis in order to regain compliance with the NASDAQ Stock Market's ("NASDAQ") minimum bid price requirement. The Company's common shares began trading on a consolidated basis on October 5, 2012, and the Company regained NASDAQ compliance on October 19, 2012.

Public Offering

• Subsequent to quarter-end, on October 17, 2012, the Company completed a public offering of 6.6 million units (the "Offering") generating net proceeds of $15.2 million intended to be used for the continued funding of ongoing drug development programs for perifosine in MM, as well as for AEZS-108 and AEZS-130.

Cash and cash equivalents, excluding the net proceeds raised in the Offering subsequent to quarter-end, totalled $33.2 million as at September 30, 2012, compared to $46.9 million as at December 31, 2011.

Juergen Engel, PhD, Aeterna Zentaris President and Chief Executive Officer, commented, "This has been quite an eventful quarter for our Company. At the drug development level, we focused on opening new sites and increasing patient recruitment for our ongoing Phase 3 trial of perifosine in multiple myeloma. Meanwhile, our partner, Yakult, continued to make progress with a Phase 1 trial of perifosine in the same indication in Japan.

As for AEZS-108, we filed a SPA with the FDA for our upcoming Phase 3 trial in endometrial cancer. Earlier this week, we were pleased to report the initiation of the Phase 2 portion of the investigator driven Phase 1/2 trial of AEZS-108 in prostate cancer.

Regarding AEZS-130 as an oral diagnostic test for AGHD, all efforts are concentrated on filing an NDA in the first quarter of 2013. We also announced that a first patient had been recruited for an investigator driven Phase 2A trial of AEZS-130 in cancer-induced cachexia.

2013 looks promising, and we remain confident that the market will come to recognize the full potential of our innovative pipeline."

Dennis Turpin, CPA, CA, Senior Vice President and Chief Financial Officer at Aeterna Zentaris stated, "As of September 30, 2012, including net proceeds from the Offering, we had a pro forma cash and cash equivalents position of $48.4 million which means that we should be well poised to continue to move our key product candidates through the pipeline."

CONSOLIDATED RESULTS AS AT AND FOR THE THIRD QUARTER ENDED SEPT. 30, 2012

Revenues were $7.1 million for the quarter ended September 30, 2012, compared to $9.5 million for the same quarter in 2011. The decrease is largely attributable to lower deliveries of Cetrotide^® to certain customers and to the relative weakening of the euro against the US dollar.

R&D costs, net of refundable tax credits and grants were $4.3 million for the quarter ended September 30, 2012, compared to $5.7 million for the same quarter in 2011. The comparative decrease is attributable to lower third-party costs associated with the development of perifosine and AEZS­108, combined with the weakening of the euro against the US dollar.

Net finance income (costs) totalled $(0.9) million for the quarter ended September 30, 2012, compared to $9.3 million for the same quarter in 2011. The significant fluctuation in net finance (costs) income is mainly due to the change in fair value of our warrant liability, as well as to (losses) or gains due to changes in foreign currency exchange rates, which are mainly related to the period-over-period continued weakness of the Euro against the U.S. dollar.

Net loss amounted to $6.6 million, or $0.35 per basic and diluted share for the quarter ended September 30, 2012, compared to a net income of $1.1 million, or $0.07 per basic and $0.06 per diluted share, for the same quarter in 2011. The significant increase in net loss for the three-month period ended September 30, 2012, as compared to the same period in 2011, is due largely to lower net finance income, partly compensated by lower R&D and SG&A expenses.
