ROCKVILLE, MD, USA I November 28, 2011 I Micromet, Inc. (NASDAQ: MITI – News) today announced that it has initiated a phase 2 trial of its lead product candidate blinatumomab (MT103) in adult patients with relapsed or refractory (r/r) B-precursor acute lymphoblastic leukemia (ALL). Blinatumomab is the first of a new class of agents called BiTE® antibodies, designed to harness the body’s T cells to kill cancer cells.
"Relapsed/refractory acute lymphoblastic leukemia is a difficult to treat disease that has seen no meaningful improvement in decades," said Professor Max Topp, Department of Internal Medicine II, University of Wuerzburg and the study’s coordinating investigator for Europe. "To date blinatumomab has demonstrated an unprecedented level of efficacy and adequate safety in a patient population with limited therapeutic options."
This phase 2, single-arm study will evaluate the efficacy and safety of blinatumomab in approximately 65 patients with relapsed/refractory Philadelphia-negative B-precursor ALL. Patients will receive blinatumomab daily for 28 days followed by two weeks off blinatumomab over a six week treatment cycle. Patients who achieve a complete remission (CR) or complete response without full recovery of platelets (CRh*) within two cycles of treatment will receive up to three additional cycles of consolidation treatment. The primary endpoint of the study is CR/CRh*. Secondary endpoints include duration of response and overall survival. The study will be conducted at approximately 40 leading cancer centers in the U.S. and EU. The Company currently expects to complete enrollment in this trial by year end 2012.
“In the event that initial data generated from this trial are compelling, we plan to discuss with the FDA potential avenues to accelerate blinatumomab’s path to market,” said Jan Fagerberg, MD, Ph.D., Micromet’s Senior Vice President and Chief Medical Officer.

Blinatumomab Clinical Experience in Adult R/R ALL
Interim results from a Phase 2 trial presented at the 2011 Meeting of the European Hematology Association show that blinatumomab produced a high CR rate in adult patients with ALL who had relapsed following treatment with standard therapy. 75% of patients (9 of 12) achieved a CR or CRh* following treatment with blinatumomab1. All nine responding patients achieved a complete molecular response, or had no evidence of leukemic cells in their bone marrow, a key prognostic factor for patient survival. Notably, four patients with genetic abnormalities typically associated with poorer outcomes all achieved a CR or CRh*. The most common clinical adverse events were fever, peripheral edema and fatigue. Treatment of two of the twelve patients was interrupted due to fully reversible and manageable central nervous system (CNS) events.
About Blinatumomab
Blinatumomab (MT103) is a next-generation monoclonal antibody designed to direct the body’s cell destroying T-cells against CD19, a protein expressed on the surface of B-cell derived acute lymphoblastic leukemias and non Hodgkin’s lymphomas.
Micromet has received orphan drug designation from the European Medicines Agency for blinatumomab for the treatment of acute lymphoblastic leukemia, mantle cell lymphoma and chronic lymphatic leukemia and from the U.S. Food and Drug Administration for the treatment of acute lymphoblastic leukemia, chronic lymphocytic leukemia and indolent B cell lymphoma.
About Relapsed/Refractory Acute Lymphoblastic Leukemia
Acute Lymphoblastic Leukemia (ALL) is an aggressive cancer of the blood and bone marrow that afflicts 5,330 patients in the U.S. annually2. Patients with ALL have abnormal white blood cells (lymphocytes) that crowd out healthy white and red blood cells and platelets, leading to infection, anemia (fatigue), easy bleeding and other serious effects. 50%−60%5,9 of patients will relapse following frontline therapy. 15 – 20%9 of patients have refractory disease, defined as failure to respond to frontline therapy. With current approaches used to treat r/r ALL, complete remission rates typically range from 20 – 30%3-6. Standard chemotherapy is associated with a mortality rate of up to 23%8. The average five-year survival rate for adult ALL patients after first relapse is 7%6.
