Repligen Corporation Reports Second Quarter Fiscal Year 2008 Financial Results

WALTHAM, Mass., Nov. 8 /PRNewswire-FirstCall/ -- Repligen Corporation today reported results for the second quarter of fiscal year 2008, ended September 30, 2007. Total revenue for the quarter was $5,352,000 compared to $2,865,000 for the second quarter of fiscal year 2007 ended September 30, 2006, an increase of $2,487,000 or 87%. Total revenue for the quarter consisted primarily of Protein A product revenue. Gross profit on product revenue for the second quarter of fiscal year 2008 was $3,744,000 (73%) compared to $1,765,000 (66%) for the same period in fiscal year 2007, an increase of $1,979,000 or 112%.

During the second quarter of fiscal year 2008, the Company reached a settlement with ImClone Systems in the patent infringement lawsuit against ImClone related to the manufacture and sale of Erbitux(R). As a result of the Settlement Agreement, the Company recorded a net gain from litigation settlement of $40,170,000 as a separate component of operating expenses.

Operating expenses, exclusive of the net gain from litigation settlement, were $4,752,000 for the second quarter of fiscal year 2008 compared to $3,961,000 for the same period in fiscal year 2007. This increase in operating expenses of $791,000 was primarily the result of other litigation expenses as well as increased external research and direct material expenses, which were partially offset by lower clinical operations costs.

Net income for the second quarter of fiscal year 2008 was $40,306,000 or $1.29 per diluted share, compared to a net loss for the second quarter of fiscal year 2007 of $863,000 or $.03 per share. Cash, cash equivalents and marketable securities as of September 30, 2007 were $62,696,000 compared to $22,627,000 as of March 31, 2007.

"We are very pleased to have monetized one of our intellectual property assets and that our Protein A business continues to provide a growing stream of revenue and profits," stated Walter C. Herlihy, President and Chief Executive Officer of Repligen Corporation. "Our financial strength will allow us to vigorously invest in our CTLA4 intellectual property, our Protein A business and our product pipeline without the financial risks normally associated with a clinical stage biotechnology company."

For the six-month period ended September 30, 2007, total revenue was $11,331,000 compared to $6,493,000 for the same period in fiscal year 2007. Gross profit on product revenue for the six-month period ended September 30, 2007 was $7,761,000 (71%) compared to $4,135,000 (68%) for the same period in fiscal year 2007. Net gain from litigation settlement for the six-month period ended September 30, 2007 was $40,170,000. Operating expenses, exclusive of the net gain from litigation settlement, were $10,746,000 for the six-month period ended September 30, 2007 compared to $7,710,000 for the same period in fiscal year 2007. Net income for the six-month period ended September 30, 2007 was $40,546,000 or $1.30 per diluted share compared to a net loss of $763,000 or $.03 per share in the same period in fiscal year 2007.

In September, we had a meeting with the FDA to discuss the positive results of our Phase 2 clinical study of RG1068, synthetic human secretin, for MRI imaging of the pancreas as well as the FDA's requirements for registration. Based on our discussion with the FDA, we believe that a single, well-controlled Phase 3 clinical trial which reproduces the Phase 2 study will be sufficient for product registration. We are currently finalizing the Phase 3 protocol and related documents and plan to initiate the Phase 3 study in the first quarter of 2008. We believe there may be more than 100,000 pancreatic MRI imaging procedures conducted in the U.S. each year that could benefit from the use of secretin.

Uridine for Bipolar Disorder

Today we reported the results from our Phase 2 clinical trial of RG2417, an oral formulation of uridine, in bipolar disorder. This was a multi-center study in which 84 patients received RG2417 or a placebo over a 6-week period. The objective of the study was to assess the safety and efficacy of RG2417 on the symptoms of bipolar depression as measured by the co-primary endpoints, the Montgomery-Asberg Depression Rating Scale (MADRS) and the Clinical Global Impression of Change in Bipolar Disorder scale (CGI-BP-C). Patients were evaluated at baseline and then weekly using these standardized tools to assess change in their symptoms. Over the six-week treatment period, the study demonstrated a statistically significant improvement in the symptoms of depression in the patients receiving RG2417 when compared to placebo on the MADRS (p=0.03) and a strong trend toward improvement on the CGI-BP-C (p=0.06). This study was conducted under a development agreement with the Stanley Medical Research Institute.

Transcription Activators for Friedreich's Ataxia

In April, we acquired the rights to intellectual property covering compounds which may have utility in treating Friedreich's ataxia. We have synthesized and evaluated more than 100 compounds for their activity and have identified several with improved potency and specificity. We are continuing to evaluate this family of compounds for activity in animal models of Friedreich's ataxia and other neurodegenerative diseases. In September, we received a $100,000 research grant from the Friedreich's Ataxia Research Alliance (FARA) to support some of the research activities. FARA is a non- profit organization dedicated to the pursuit of scientific research leading to treatments and a cure for Friedreich's ataxia.

Intellectual Property

ImClone Litigation Settlement

In September, we announced settlement with ImClone Systems, Incorporated (ImClone) in the lawsuit against ImClone for infringement of U.S. Patent No. 4,663,281 based on ImClone's manufacture and sale of Erbitux(R). The settlement provided for ImClone to pay $65 million to co-plaintiffs Repligen and The Massachusetts Institute of Technology (MIT) which resulted in net proceeds to Repligen of approximately $40 million after payment of obligations to MIT and legal expenses.

CTLA4-Ig Patent

In 2006, Repligen and The University of Michigan filed a lawsuit against Bristol-Myers Squibb (Bristol) for infringement of a U.S. patent that covers a method of treating rheumatoid arthritis with CTLA4-Ig. Bristol markets CTLA4- Ig for treatment of rheumatoid arthritis, under the brand name Orencia(R). Recently, the Court held a Markman hearing in order to interpret the meaning of the claims in the patent. In its ruling on claims construction, the Court rejected Bristol's attempt to insert a mechanistic limitation on the use of CTLA4-Ig for the treatment of rheumatoid arthritis and accepted our straightforward reading of the claim. We anticipate that Summary Judgment briefing will be complete in February and a trial will occur in April.
