News Release Details

ROCKVILLE, Md.--(BUSINESS WIRE)--Dec. 28, 2011-- Emergent BioSolutions Inc. (NYSE:EBS) today announced plans for its TRU-016 program following receipt of a notice from Abbott that it is terminating its co-development and co-commercialization agreement. Abbott’s decision is a result of the company's portfolio prioritization process. TRU-016, Emergent’s humanized anti-CD37 mono-specific protein therapeutic, recently commenced a Phase 2 clinical study for chronic lymphocytic leukemia (CLL) and is currently in the middle of Phase 1b clinical evaluation in non-Hodgkin’s lymphoma (NHL). These studies will be completed, and final study data will be available by 1H 2013.

Following the termination of the agreement, Emergent will retain worldwide rights for the development and commercialization of TRU-016, and Abbott will be obligated to provide certain forms of transition assistance to Emergent for a certain period of time. Emergent does not expect that termination of the Abbott agreement will have a material impact on its planned R&D expenditures for 2012.

In a separate release issued today, Emergent announced the initiation of patient dosing in the Phase 2 study (protocol 16201) of TRU-016 in combination with bendamustine for patients with relapsed CLL. The initiation of this clinical trial triggered a $6 million milestone payment to Emergent by Abbott. The Phase 2 portion of this study was initiated under the collaboration agreement following achievement of the Phase 1b study objectives and authorization for the commencement of the Phase 2 study by an independent data monitoring committee.

“Emergent remains committed to continued clinical evaluation of TRU-016 in B-cell malignancies,” said Daniel J. Abdun-Nabi, President and Chief Operating Officer at Emergent BioSolutions. “We look forward to TRU-016’s continued progress in the current ongoing clinical trials.”

The agreement will remain in effect until March 20, 2012 and provides for Abbott to assist Emergent in the transition. While the agreement remains in effect, Abbott has an obligation to pay any milestone payments that are triggered as well as half of the collaboration project costs agreed to between Abbott and Emergent.

Emergent is evaluating whether the termination will require an impairment to goodwill and intangible assets to be recorded in 2011. The Company plans to provide preliminary 2011 financial results and 2012 guidance at the J. P. Morgan Healthcare Conference in January.
