Micromet Reports Second Quarter 2007 Financial Results

BETHESDA, Md., Aug. 8 /PRNewswire-FirstCall/ -- Micromet, Inc. (“Micromet” or the “Company”), a biopharmaceutical company focusing on the development of novel, proprietary antibody-based products for cancer, inflammation and autoimmune diseases, today announced its financial results for the second quarter ended June 30, 2007.

Summarizing the quarter, Christian Itin, Ph.D., President and Chief Executive Officer of Micromet said: “With the execution of a significant collaboration with Nycomed for our MT203 antibody in May and a successful capital raise during June, we have substantially strengthened our resources for future product development. Data from additional analysis of our phase 2 clinical trial with adecatumumab in patients with metastatic breast cancer presented at ASCO in May support our focus on cancer patients with high levels of EpCAM target for our future clinical studies. We look forward to announcing additional results of our MT103 BiTE in non-Hodgkin’s lymphoma and of our preclinical programs during the second half of 2007.”

Recent Highlights: -- On May 24th, we granted to Nycomed exclusive worldwide rights to develop and commercialize MT203, a human antibody neutralizing granulocyte/macrophage colony stimulating factor (GM-CSF), which may be useful for the treatment of inflammatory and autoimmune diseases. Under the terms of the agreement, Micromet received an upfront license fee of euro 5 million (approximately $7 million), and is eligible to receive development expenses and milestone payments of more than euro 120 million (approximately $160 million) in the aggregate. The program is currently at the preclinical stage and is expected to move to clinical stage in early 2009. -- On June 4th, we reported final data from the randomized phase 2 clinical trial of adecatumumab (MT201) in metastatic breast cancer patients, including recent exploratory posthoc subgroup analyses. The additional analyses showed that all time dependent end points were in favor of patients expressing high levels of the EpCAM target. -- On June 20th, we announced a private placement involving the sale of our common stock and warrants raising net proceeds of approximately $23.5 million, after the costs of the offering. The transaction was conducted amongst a group of experienced biotechnology investors, including funds affiliated with members of our Board of Directors. -- On July 11th, Micromet’s collaborator TRACON Pharmaceuticals started the treatment of the first cancer patient in phase 1 clinical trial with D93/TRC093. This compound was licensed from Micromet in March of this year. Financial Results:

Quarter Ended June 30, 2007

For the quarter ended June 30, 2007, Micromet recognized total revenues of $3.1 million, compared to $5.0 million for the same period in 2006. Revenue recognized under collaboration agreements decreased by $1.9 million during the second quarter of 2007 as compared to the same period in 2006 due to certain nonrecurring revenue received in 2006 from Cell Therapeutics, Inc. of $1.9 million relating to a previously terminated collaboration.

Total operating expenses were $11.1 million for the quarter ended June 30, 2007, compared to $34.4 million for the same period in 2006. The majority of the decrease relates to a one-time in-process research and development charge of $20.9 million taken in 2006 in connection with the CancerVax merger. Recurring R&D expenses decreased $2.8 million from the prior year primarily due to a decrease in R&D stock-based compensation charges of $1.8 million as a result of one-time stock option grants issued in 2006 following the CancerVax merger that included accelerated vesting provisions. The remainder of the R&D expense decrease is a result of the completion of two phase 2a clinical trials with adecatumumab in mid-2006. General and administrative expenses of $4.4 million for the quarter ended June 30, 2007 were slightly above the $4.0 million for the same period in 2006. This increase results from an $800,000 charge to facility expenses as a result of the finalization of our lease exit liability costs related to the former CancerVax headquarters, which are now fully sublet, and from the increased costs of being a public company post- merger, including U.S.-based personnel and legal, investor relations, auditing and tax services. This increase was substantially offset by a decrease in G&A stock-based compensation expense of $1.5 million resulting from the same 2006 one-time stock option grant referred to above.

Micromet has recorded the warrants issued in connection with the June 2007 sale of common stock as a liability in its June 30, 2007 balance sheet at their fair value of $6.4 million determined using a Black-Scholes option- pricing model and will remeasure them at each reporting period until exercised or expired. Changes in the fair value of the warrants are reported in the statements of operations as non-operating income or expense. Other income (expenses) for the quarter ended June 30, 2007 includes $522,000 of income related to the decrease in fair value of the warrant liability from original issuance date.

Other income for the quarter ended June 30, 2007 also includes the effect of resolving certain withholding tax duty owed on past royalty payments made to collaborators who reside outside of Germany. During the first quarter of 2007, we paid $1.3 million, which was accrued in prior years, to the German tax authorities in order to settle the outstanding liability, while pursuing the refunds through our collaborators. During the second quarter of 2007, we received notification of refunds aggregating $800,000 of this total because the recipients of these royalty payments were exempt from withholding taxes. This $800,000 benefit was included in other income.

For the quarter ended June 30, 2007, Micromet reported a net loss of $6.5 million, or $0.20 per basic and diluted share, compared to a net loss of $29.5 million, or $1.18 per basic and diluted share, for the same period in 2006.

Six Months Ended June 30, 2007

For the six months ended June 30, 2007, Micromet recognized total revenues of $5.8 million, compared to $9.1 million for the same period in 2006. Revenue recognized under collaboration agreements decreased by $3.3 million during the six months ended June 30, 2007 as compared to the same period in 2006 due to certain nonrecurring revenue received in 2006 from Cell Therapeutics, Inc. of $1.9 million relating to a previously terminated collaboration. The remainder of the decrease resulted from lower collaboration revenues related to reimbursement for the adecatumumab phase 2a clinical trials that were completed in mid-2006.

Total operating expenses were $21.4 million for the six months ended June 30, 2007, compared to $40.1 million for the same period in 2006. The majority of the decrease period over period relates to a one-time in-process research and development charge of $20.9 million taken in 2006 in connection with the CancerVax merger. After considering this unusual charge, recurring R&D expenses for the six months ended June 30, 2007 decreased by $0.6 million over the same period in the prior year. A decrease in R&D stock-based compensation charges of $1.2 million as a result of one-time stock option grants issued in 2006 that contained accelerated vesting provisions, was partially offset by the payment of a license fee of $0.5 million to Applied Molecular Evolution, Inc. (subsequently acquired by Eli Lilly and Company) that was triggered by our D93 license granted to TRACON. General and administrative expenses for the six months ended June 30, 2007 were $7.9 million as compared to $5.2 million for the same period in 2006. This increase results from an $800,000 charge to facility expenses as a result of the finalization of our lease exit liability costs related to the former CancerVax headquarters, which are now fully sublet, and from the increased costs of being a public company post- merger, including US-based personnel, legal, investor relations, auditing and tax services. This increase was partially offset by a decrease in G&A stock- based compensation expense of $0.9 million resulting from the same 2006 one- time stock option grant referred to above.

Other income (expenses) for the six months ended June 30, 2007 includes $522,000 of income related to the decrease in fair value of the warrant liability from original issuance date related to warrants issued in connection with the June 2007 private placement of common stock and the $800,000 benefit of resolving a portion of the withholding tax duty owed on past royalty payments made to collaborators who reside outside of Germany, both described further above.

For the six months ended June 30, 2007, Micromet reported a net loss of $14.1 million, or $0.44 per basic and diluted share, compared to a net loss of $31.6 million, or $1.47 per basic and diluted share, for the same period in 2006.

About Micromet, Inc. (http://www.micromet-inc.com)

Micromet, Inc. is a biopharmaceutical company focusing on the development of novel, proprietary antibody-based products for cancer, inflammation and autoimmune diseases. Three product candidates are currently in clinical trials. MT103, also known as MEDI-538, is the first product candidate based on Micromet’s novel BiTE(R) antibody product development platform and is being evaluated in a phase 1 clinical trial for the treatment of patients with non- Hodgkin’s lymphoma. The BiTE antibody product development platform is based on a unique, antibody-based class of drug candidates that leverages the cytotoxic potential of T cells in the treatment of cancer. T cells are the most powerful ‘killer cells’ of the human immune system. Micromet has established a collaboration with MedImmune, Inc. for MT103/MEDI-538. The second clinical stage product candidate is adecatumumab, also known as MT201, a recombinant human monoclonal antibody which targets EpCAM expressing tumors. Adecatumumab is being developed for the treatment of patients with breast cancer. A phase 2a clinical trial in this indication has been completed, and a phase 1b trial evaluating the safety and tolerability of MT201 in combination with docetaxel is currently ongoing in patients with metastatic breast cancer. Micromet has established a collaboration with Merck Serono for adecatumumab (MT201). Our third clinical stage product candidate is D93, also known as TRC093, a first- in-class humanized monoclonal antibody that inhibits angiogenesis and tumor cell growth by binding cleaved collagen. This product candidate is in phase 1 clinical trials and is being developed by TRACON Pharmaceuticals for the treatment of patients with cancer and age-related macular degeneration pursuant to license agreement under which Micromet has granted TRACON the worldwide rights to develop and commercialize D93/TRC093. In addition, Micromet has established a collaboration with Nycomed for the development and commercialization of MT203, Micromet’s human antibody neutralizing the activity of granulocyte/macrophage colony stimulating factor (GM-CSF), which has potential applications in the treatment of inflammatory diseases, such as rheumatoid arthritis, as well as autoimmune diseases.
