Micromet Reports Fourth Quarter and Full Year 2006 Financial Results

CARLSBAD, Calif., March 16 /PRNewswire-FirstCall/ -- Micromet, Inc. (“Micromet” or the “Company”), a biopharmaceutical company focusing on the development of novel, proprietary antibody-based products for cancer, inflammatory and autoimmune diseases, today announced its financial results for the fourth quarter and the full year ended December 31, 2006. As a result of the reverse merger between Micromet AG and CancerVax Corporation that was completed on May 5, 2006, the financial information included below for the fiscal year 2005 and through May 5, 2006 is based solely on Micromet AG’s historical financial statements without the inclusion of the financial results of CancerVax.

Recent Highlights: -- Micromet received a $10 million milestone payment from Merck Serono following the completion of phase 2 clinical trials of adecatumumab (MT201) and amended their collaboration agreement to continue development of adecatumumab. -- Micromet presented clinical results from a phase 2a trial of adecatumumab in metastatic breast cancer at the annual Breast Cancer Meeting in San Antonio, Texas. -- Micromet presented encouraging interim data from an ongoing phase 1 clinical trial of MT103 during an oral presentation session at the 48th Annual Meeting of the American Society of Hematology (ASH) in Orlando. MT103 is being developed for the treatment of patients with B cell- derived lymphomas and leukemias. -- Micromet published preclinical results for its humanized antibody D93 in the International Journal of Cancer. -- Morphotek obtained an exclusive worldwide license from Micromet for an antibody targeting an antigen with potential for the treatment of certain cancers, including melanoma. -- Micromet granted TRACON Pharmaceuticals exclusive worldwide rights to develop and commercialize Micromet’s D93 antibody with a novel mode of action for the treatment of cancer. Under the terms of the agreement, TRACON will pay Micromet an upfront license fee and milestone payments of more than $100 million, if D93 is successfully developed and commercialized. Financial Results: Quarter Ended December 31, 2006

For the three months ended December 31, 2006, Micromet recognized revenues of $13.8 million, compared to $8.7 million for the same period in 2005. Included in 2006 revenues was the receipt of a $10.0 million milestone payment from Merck Serono following the completion of two phase 2 clinical trials for adecatumumab. Total operating expenses were $10.9 million for the three months ended December 31, 2006, compared to $9.4 million for the same period in 2005. For the three months ended December 31, 2006, Micromet reported net income of $3.4 million, or $0.11 per basic and diluted share, compared to a net loss of $6.7 million, or $0.42 per basic and diluted share, for the same period in 2005. The positive net income is due primarily to the milestone payment received from Merck Serono.

Year Ended December 31, 2006

Revenues for the year ended December 31, 2006 were $27.6 million, compared to $25.7 million for 2005. For the year ended December 31, 2006, Micromet reported operating expenses of $61.2 million, compared to $35.4 million for the same period in 2005. In connection with the merger with CancerVax, Micromet recorded a non-recurring, non-cash charge of $20.9 million in the second quarter due to the immediate write-off of CancerVax’s in-process research and development programs. For the year ended December 31, 2006, net loss was $34.0 million, or $1.29 per basic and diluted share, compared to $19.1 million, or $3.70 per basic and diluted share, for 2005.

Micromet’s cash and cash equivalents were $24.3 million as of December 31, 2006. Based on the status of our development programs, we believe this cash balance is sufficient to fund our operations into the second quarter of 2008.

Summary of Recent Events:

Interim Data from an Ongoing Phase 1 Clinical Trial of MT103

On December 12, 2006, Micromet presented interim data from an ongoing phase 1 European clinical trial of MT103 (also known as MEDI-538) during an oral presentation session on “Targeted Therapy of Non-Hodgkin-Lymphoma (NHL)” at ASH. MT103, which is being co-developed with MedImmune, is a drug being developed for the treatment of patients with B cell-derived lymphomas and leukemias. The interim data indicated that MT103 is well tolerated overall at the dose levels administered, and Micromet cited the observation of clinical responses in heavily pre-treated, advanced-stage NHL patients.

Phase 2a Data in Metastatic Breast Cancer with Adecatumumab Presented at San Antonio Breast Cancer Meeting

On December 15, 2006, Micromet and its collaborative partner Merck Serono reported at the San Antonio Breast Cancer Meeting, San Antonio, Texas, on the outcome of a phase 2a trial testing the activity of adecatumumab in metastatic breast cancer. Adecatumumab, a fully human monoclonal antibody targeting tumor cells overexpressing the epithelial cell adhesion molecule (EpCAM), was assessed as a single agent for efficacy and safety in patients with EpCAM- positive metastatic breast cancer (N=109). This clinical trial evaluated adecatumumab at two dose levels in patients with high and low EpCAM expression. While the primary endpoint was not met, the results indicated dose dependent activity of adecatumumab, as well as a trend towards longer time to progression for patients expressing high levels of EpCAM on their primary tumor. Adecatumumab was generally well tolerated with the observation of a dose-dependent increase in the incidence of Grade 1-2 adverse events (AEs). Adecatumumab is also being evaluated in combination with docetaxel in an ongoing phase 1b clinical trial in Europe. The information from the current trials will be used to further refine the targeted patient population and dosing regimens, as well as to explore other solid tumor settings.

$10 million Milestone Payment from Merck Serono

On December 4, 2006, Micromet announced that it had received a $10 million milestone payment from Merck Serono. The milestone payment was made in connection with the completion of two phase 2 clinical trials with adecatumumab evaluated as a single agent for the treatment of patients with metastatic breast cancer and prostate cancer, respectively.

Merck Serono Collaboration Amendment

On December 5, 2006, Micromet announced that Merck Serono and Micromet had agreed to amend their collaboration agreement under which the two companies are developing adecatumumab. The companies are planning additional exploratory and clinical activities to identify the optimal dosing regimen, as well as explore additional indications for adecatumumab and initiate a new phase 1 monotherapy study for the treatment of patients with solid tumors which we plan to begin in 2007. Merck Serono will reimburse Micromet for its costs incurred in connection with the development program.

First International EpCAM Symposium

On January 29, 2007 Micromet reported in the British Journal of Cancer on proceedings from an international symposium on EpCAM (CD326). EpCAM is one of the most frequently and intensely expressed tumor-associated antigens known. EpCAM overexpression is linked to poor survival in several tumor types including breast, ovarian and pancreatic cancer; is associated with increased metastatic potential; and is found on tumor stem cells. Micromet has two product candidates targeting EpCAM in development which target EpCAM: adecatumumab, a human antibody, which is in clinical development, and MT110, a BiTE molecule, which is in formal preclinical development.

Morphotek License

On February 12, 2007, Micromet and Morphotek Inc., a privately held biopharmaceutical company focused on the discovery and development of therapeutic monoclonal antibodies, announced that Morphotek exercised its option under a 2004 agreement to obtain an exclusive worldwide license for an antibody targeting an antigen with potential activity for the treatment of certain cancers, including melanoma. Under the terms of the agreement with Morphotek, Micromet has received a payment in connection with the exercise of the option by Morphotek and is eligible to receive development milestone payments and royalties on net sales. Morphotek is planning to file an investigational new drug (IND) application later this year and to commence clinical trials in 2008.

TRACON License

Today, Micromet announced an agreement granting TRACON Pharmaceuticals, Inc., a privately held biopharmaceutical company focused on the development of products for cancer treatment, the exclusive worldwide rights to develop and commercialize Micromet’s D93 antibody with a novel mode of action for the treatment of cancer. Under the terms of the agreement, TRACON will be responsible for all development and commercial activities and plans to initiate a phase 1 clinical trial in the second half of this year. Micromet will receive license fees and milestone payments from TRACON of $100 million, if D93 is successfully developed and commercialized. In addition, we will receive royalties on worldwide sales.

Summarizing the events, Christian Itin, Ph.D., President and Chief Executive Officer of Micromet said: “We are well on track with the post-merger integration and continue to make progress with our entire product pipeline. On the clinical development front, we have reported interim phase 1 results for the MT103 NHL program at the recent ASH meeting in Orlando and phase 2a results at the San Antonio Breast Cancer Meeting for adecatumumab and look forward to continuing to move these programs forward. Our financial position was further strengthened with the receipt of the $10 million milestone payment from Merck Serono on the adecatumumab program in the fourth quarter of 2006. Furthermore, we expect to announce additional results of our clinical and preclinical programs, as well as business development efforts during the first half of 2007.”

2007 Outlook: -- Micromet and its partner MedImmune plan to initiate a first clinical trial with MT103/MEDI-538 in non-Hodgkins lymphoma patients in the U.S. and a phase 2 clinical trial in acute lymphatic leukemia in Europe. -- Micromet and its partner Merck Serono will continue their ongoing phase 1b trial in metastatic breast cancer with adecatumumab in combination with docetaxel and are planning to initiate a phase 1 clinical trial to test adecatumumab in other solid tumors. -- Micromet plans to advance its preclinical development program for MT110 towards an IND/IMPD filing in 2007, and is evaluating strategic corporate collaborations with this program. -- Micromet and its partner TRACON Pharmaceuticals plan to initiate a phase 1 clinical trial for D93 in the second half of 2007. -- Micromet is continuing its outlicensing activities with respect to MT203 and MT204. -- Micromet will continue its research and development programs for the discovery of new BiTE product candidates.
