ROCKVILLE, Md., Aug 17, 2011 –

Emergent BioSolutions Inc. (NYSE:EBS) today announced the initiation of a Phase 1b/2 study (16011) of TRU-016 in combination with rituximab and bendamustine for patients with relapsed indolent non-Hodgkin’s B-cell lymphomas, including follicular lymphoma, small lymphocytic lymphoma and marginal zone lymphoma. TRU-016 is a CD37-directed Small Modular ImmunoPharmaceutical(TM) protein therapeutic in development for the treatment of B-cell malignancies. TRU-016 is being developed in collaboration with Abbott.

“Although patients show a high rate of clinical response to first line therapies they often relapse and in many cases, develop a resistance to treatment,” said Dr. Scott Stromatt, Vice President of Clinical Research and Chief Medical Officer at Emergent BioSolutions. “Our preclinical studies show that when used together, TRU-016 and bendamustine resulted in increased anti-tumor activity beyond results achieved when either drug was administered alone. TRU-016 is also synergistic with rituximab in preclinical models. Based on these data, as well as data from our ongoing clinical studies of TRU-016 for chronic lymphocytic leukemia, we believe that TRU-016 in combination with bendamustine and rituximab could produce meaningful results in patients with indolent NHL.”

The Phase 1b portion is a dose escalation study to determine the Phase 2 dose of TRU-016 given in combination with rituximab and bendamustine. In this portion of the trial, up to 12 patients will receive two dose levels of TRU-016 in combination with rituximab and bendamustine administered intravenously. The primary safety endpoint for the Phase 1b portion of the study is the incidence of dose-limiting toxicities (DLTs).

The Phase 2 portion will be an expansion study of approximately 76 additional patients to examine the safety and efficacy of TRU-016 in combination with 375 mg/m² of rituximab and 90 mg/m² of bendamustine, versus bendamustine and rituximab. The primary efficacy endpoint for the Phase 2 portion of the study is complete response (CR) rate as determined by using the Revised Response Criteria for Malignant Lymphoma. The pharmacokinetics and pharmacodynamics of TRU-016 will be studied in both phases of the study.

The total expected enrollment for both phases of this study is expected to be 88 patients, all of whom have a confirmed diagnosis of relapsed indolent B-cell lymphoma, and who have failed prior treatments. Study enrollment is expected to be completed by the end of 2012. Additional information about this Phase 1b/2 clinical study can be found at www.clinicaltrials.gov (protocol 16011).

About non-Hodgkin’s Lymphoma (NHL)

According to the National Cancer Institute, there are approximately 65,980 cases of NHL diagnosed each year, with close to 30% of these cases resulting in death. NHL is a broad range of malignant lymphoid disorders that are categorized on the basis of aggressiveness and cell of origin. Indolent or slow-growing NHL causes few symptoms, particularly early in the natural history of the disease, making early detection difficult. The majority of patients with indolent NHL present with Stage III or IV disease. Most patients with NHL requiring treatment receive rituximab in combination with chemotherapy as initial treatment; however, many patients become refractory to both chemotherapy and rituximab.

About TRU-016

TRU-016 is a CD37-directed protein therapeutic in development for the treatment of B-cell malignancies. TRU-016 is being developed in collaboration with Abbott. TRU-016 uses a different mechanism of action than currently marketed CD20-directed therapies. As a result, TRU-016 may provide patients with improved therapeutic options and enhance efficacy when used alone or in combination with chemotherapy and/or other immunotherapeutics. TRU-016 is currently in Phase 1b/2 development for chronic lymphocytic leukemia and non-Hodgkin’s lymphoma.

Lansing-based Emergent BioSolutions picked up its U.S. rival’s anthrax vaccination technology for $2 million, strengthening the company’s ability to make a second anthrax vaccination.

According to excerpts from the article:

In Lansing, the acquisition of VaxGen Inc.’s vaccine could add a second product line at a new plant.

Based in Rockville, Md., Emergent currently makes the BioThrax vaccine in Lansing.

The U.S. Department of Health and Human Services is expected to seek 25 million doses of such a vaccine later this year, Emergent said.

“We felt this was the right opportunity for our company at the right time,” Emergent Chairman and Chief Executive Officer Fuad El-Hibri said in the company’s announcement.

$9.5 million development contract to fund non-clinical and clinical studies of anthrax immune globulin (AIG) over next 24 months

ROCKVILLE, MD., September 27, 2007—Emergent BioSolutions Inc. (NYSE: EBS) announced today that it has received a development contract, valued at up to $9.5 million, in support of non-clinical and clinical studies of the company’s anthrax therapeutic, or AIG, product candidate.  This product candidate is an immune globulin being developed as an intravenous therapeutic for treatment of patients who present with symptoms of anthrax disease following exposure to anthrax.

This development contract has been funded in whole or in part from Federal funds from the National Institute of Allergy and Infectious Diseases (NIAID), National Institutes of Health (NIH) and the Biomedical Advanced Research and Development Authority (BARDA), Department of Health and Human Services (HHS), under Contract No. HHSN272200700034C.

Fuad El-Hibri, chairman and chief executive officer of Emergent BioSolutions, stated, “We are very pleased to have continuing support for AIG from NIAID and BARDA and commend the leadership throughout HHS for their commitment to funding the development of effective medical countermeasures against this deadly biological agent.  With the continued development funding of our AIG candidate, in conjunction with the $448 million contract with HHS announced yesterday regarding procurement of 18.75 million doses of our BioThrax anthrax vaccine for the strategic national stockpile, we are very encouraged by the government’s support of our anthrax franchise.  We look forward to continuing to be a leading participant in the U.S. government’s effort to build a robust domestic biodefense industry.”

Under terms of the development award, the funds will be used to conduct various studies on AIG, including (i) non-clinical studies in support of efficacy; and (ii) a Phase I/II clinical study to evaluate pharmacokinetics and safety.  Previously, in August 2006 the company received $3.9 million from NIAID in support of the company’s AIG program.  When combined with the $9.5 million under this new development award, the total amount of government funding for AIG to date is over $13 million.

About Anthrax Immune Globulin (AIG)

Emergent BioSolutions’ anthrax immune globulin (AIG) is being developed as an intravenous therapeutic for treatment of patients who present with symptoms of anthrax disease resulting from the release of anthrax toxins into the body and for whom the use of the vaccine is no longer an effective option.  If successfully developed, AIG could be prescribed for administration in these circumstances either as a monotherapy or in conjunction with an antibiotic.

AIG is being developed using plasma collected from healthy donors who have been vaccinated with BioThrax® (Anthrax Vaccine Adsorbed), Emergent BioSolutions’ anthrax vaccine, which is the only vaccine approved by the U.S. Food and Drug Administration for the prevention of anthrax infection.

The company has collected a sufficient amount of plasma to initiate manufacturing of AIG under cGMP using a validated and approved process.  This manufacturing process entails fractionating the plasma and purifying the immune globulin.  The company has signed an exclusive license with Talecris Biotherapeutics, Inc., a North Carolina-based biopharmaceutical company and leading fractionation provider, to fractionate, purify and fill AIG at Talecris’ FDA-approved facilities.  To date, the first full-scale lot of AIG has been manufactured under cGMP requirements at Talecris.  The company has scheduled plans to complete a second full-scale lot of AIG.

ROCKVILLE, Md.-(Business Wire)-April 16, 2009 – Emergent BioSolutions Inc. (NYSE:EBS) announced today that late on April 15^th, HHS requested that each bidder in the competitive range for the rPA contract submit its product development plans to FDA for review in advance of an award. Emergent had already requested and is presently scheduling a meeting with the FDA as part of its pre-award activity. The Company intends to incorporate any FDA comments into its rPA development plan. Emergent will continue to move its rPA program forward to position the company to execute on the anticipated contract, once awarded.

“We strongly support this step by HHS, which potentially reduces development risk for our rPA vaccine candidate. We remain confident that we are well-positioned and competitive to receive any award granted by HHS for the development and procurement of the rPA vaccine. We look forward to continuing our long-standing relationship with the US Government as the proven and preeminent supplier of medical countermeasures to protect our nation,” said Fuad El-Hibri, chairman and chief executive officer of Emergent BioSolutions.

As with any government solicitation of this size and scope, there are no assurances that HHS will not impose additional requirements, which may further extend contract negotiations.

This action has no impact on the company’s existing contracts with HHS to supply BioThrax®, the only FDA licensed anthrax vaccine, for the Strategic National Stockpile (SNS). This year Emergent is completing the delivery of 18.75 million doses of BioThrax for inclusion in the SNS. Also this year, following the completion of that delivery, Emergent will begin to supply HHS with an additional 14.5 million doses of BioThrax under a follow-on contract. The total value of these two procurement contracts with HHS for BioThrax exceeds $800 million.
