Optimer Pharmaceuticals Reports Third Quarter 2009 Financial Results

SAN DIEGO, Nov. 3 /PRNewswire-FirstCall/ -- Optimer Pharmaceuticals, Inc. (Nasdaq: OPTR) today reported financial results for the third quarter ended September 30, 2009. Optimer reported a net loss for the third quarter of 2009 of $9.4 million, or $0.28 per share, which was in line with the Company's expectations. This compares to a net loss for the third quarter of 2008 of $9.2 million, or $0.31 per share. Research and development expenses in the third quarter of 2009 were $7.2 million, compared to $7.9 million in the third quarter of 2008. The decrease was primarily due to the completion of the Pruvel(TM)(prulifloxacin) Phase 3 trials. The decrease was partially offset by an increase in expenses to prepare regulatory filings related to fidaxomicin and Pruvel.


As of September 30, 2009, Optimer held cash, cash equivalents and short-term investments of $42.5 million.

"It's been another strong quarter for Optimer, marked by significant interaction with the medical community on the Phase 3 data profiling the characteristics and attributes of fidaxomicin and Pruvel," said Michael N. Chang, Ph.D., Optimer's President and Chief Executive Officer. "Additional data from the North American Phase 3 fidaxomicin trial were recently presented at the ICAAC and IDSA medical conferences further demonstrating why we believe fidaxomicin has the potential to be the optimal treatment for CDI."

Corporate Updates

  • Following discussions with the FDA, Optimer has elevated global cure to a secondary endpoint from an exploratory endpoint in the second Phase 3 fidaxomicin trial. Given the significant problem with recurrence in CDI patients, Optimer believes that the medical community is placing greater emphasis on global cure, defined as a cure without a recurrence. The global cure rate of fidaxomicin versus vancomycin was 77.7% versus 67.1% (p=0.006) in Optimer's North American Phase 3 trial.
  • Optimer expects to complete enrollment of the second Phase 3 trial of fidaxomicin in 2009, and anticipates reporting top-line data in the first quarter of 2010. The Company continues to engage in partnering discussions regarding fidaxomicin to maximize its value.
  • Optimer recently entered into a number of transactions involving OBI, the Company's Taiwan subsidiary, to provide OBI with funding for the development of two of Optimer's early-stage, non-core programs, OPT-88 and OPT-822/821, and to allow Optimer to focus on its late-stage anti-infective programs, fidaxomicin and Pruvel. Pursuant to these transactions, Optimer assigned to OBI certain patent rights, information and know-how related to OPT-88, a preclinical product candidate for the treatment of osteoarthritis, and OPT-822/821, a carbohydrate-based cancer immunotherapy product candidate. Optimer is eligible to receive up to $10 million in milestone payments and single-digit royalties on net sales for any product developed and commercialized under the programs. To provide capital for OBI's development of OPT-88 and OPT-822/821, Optimer and a group of new investors purchased approximately $3.7 million and $2.5 million, respectively, in new OBI common shares. Also in connection with the transactions, Optimer sold forty percent of its pre-transaction OBI common shares to the new investors for proceeds of $2.1 million. Optimer maintains a sixty percent ownership interest in OBI following the completion of these transactions.

Recent Corporate Highlights

  • Three fidaxomicin-related abstracts from Optimer's North American Phase 3 study in patients with Clostridium difficile infection (CDI) were presented at the 47th Annual Meeting of the Infectious Diseases Society of America in October 2009. Clinical investigator Mark Miller, M.D., presented data showing that patients treated with fidaxomicin had a faster time to resolution of diarrhea compared to those treated with vancomycin. Faster time to resolution of diarrhea may reduce the spread of CDI in healthcare facilities and improve patients' quality of life. Clinical investigator Kate Mullane, D.O., presented data showing that treatment with fidaxomicin compared to vancomycin in patients also receiving concomitant antibiotics resulted in higher clinical cure rates, lower recurrence rates and improved global cure rates.
  • Seven fidaxomicin-related abstracts from Optimer's North American Phase 3 study were presented at the 49th Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) in September 2009. The additional data presented highlight fidaxomicin's unique profile as a new antibiotic class with beneficial characteristics for treating CDI such as lower recurrence rates, reduced risk of vancomycin-resistant enteroccoci (VRE) acquisition, favorable pharmacokinetic profile, and a safety profile comparable to that of vancomycin.
  • The full data analysis from the second Phase 3 clinical study for Pruvel was presented at ICAAC in September 2009. Data presented by primary investigator Robert Steffen, M.D., showed that Pruvel shortened recovery time in adult travelers suffering from infectious diarrhea.
  • The United States Patent and Trademark Office recently issued a patent which covers the composition of matter of CEM-101/(OP-1068). CEM-101/(OP-1068) is a macrolide derivative originally developed by Optimer and licensed to Cempra Pharmaceuticals who recently completed a Phase 1 clinical trial for the treatment of respiratory infections.
