Micromet, Inc. (NASDAQ: MITI) yesterday evening announced the presentation of pre-clinical data on its BiTE antibody MT112/BAY 2010112, discovered and developed in collaboration with Bayer HealthCare Pharmaceuticals, at the 102^nd Annual Meeting of the American Association for Cancer Research (AACR) in Orlando, Florida.

The data (poster # 4561) demonstrate the potent activity of the BiTE antibody against human cancer cell lines and inhibition of tumor growth in animal models.  MT112/ BAY 2010112 directed human and non-human primate T cells against PSMA-positive human prostate cancer cells, resulting in highly efficient cancer cell destruction. In mice, daily doses of MT112/BAY 2010112 as low as 0.05 milligram/kilogram were sufficient to inhibit growth of tumors from human prostate cancer cells.  » Read more...

Micromet, Inc. (NASDAQ: MITI) today announced that MedImmune, licensee for Micromet’s MT111, plans to initiate a Phase 1 trial in patients with advanced gastrointestinal cancers based on an investigational new drug (IND) application recently accepted by the U.S. Food and Drug Administration (FDA).

MT111, also known as MEDI-565, is a BiTE® antibody designed to direct a patient’s T cells, the body’s most potent killer cells, against cancer cells that express carcinoembryonic antigen (CEA). CEA is a protein found on the surface of a number of gastrointestinal cancers, including colorectal, esophageal and gastric cancers.

Micromet Inc (NASDAQ:MITI), a biotech company located in the US and in Germany, today announced the start of two Phase II trials of Blinatumomab, a so-called BiTE antibody which is designed to recruit T killer cells of the patient’s body to the cancer cells.

The so-called BLAST study (Blinatumomab Adult ALL MRD Study of T cell engagement) is designed to evaluate the efficacy, safety and tolerability of blinatumomab in up to 130 adult patients suffering from B-precursor acute lymphoblastic leukemia (ALL) who received chemotherapy but still have leukemia cells in the bone marrow (so-called minimal residual disease – MRD). About 70 centers in Europe and the US will take part in the study which will take about 2 years to complete. Primary endpoint is MRD response, i.e. disappearance of leukemia cells in the bone marrow.  » Read more...

In several clinical trials, antibody company Micromet has demonstrated outstanding efficacy and safety of its bispecific BiTE antibodies which come with two binding sites: one for a cancer target and a second one for a T cell. As a result, T cells are recruited and guided directly to the tumor cell, initiating cancer cell death in a serial fashion.

In this week’s PNAS, researchers of the company demonstrate that the BiTE antibodies also can overcome the notorious resistance against conventional monoclonal antibodies arising in many cancer patients.

The researchers converted the anti-EGFR antibodies cetuximab (Erbitux) and panitumumab (Vectibix) into BiTE antibodies by adding the binding site for T cells. In animal models, these BiTE antibodies then showed a remarkably high potency (in the sub-picomolar range) against cancer cells with KRAS and BRAF-mutations which made them resistant to the original monoclonal antibodies.  » Read more...

- Update Presented at the 15^th Annual Congress of the European Hematology Association (EHA) -

Micromet, Inc. (NASDAQ: MITI) today announced updated clinical data from a Phase 1 and a Phase 2 trial, respectively, of its lead product blinatumomab (MT103). The data were presented at the 15^th Annual Congress of the European Hematology Association (EHA) in Barcelona, Spain.

Results of the analysis from a Phase 2 trial in adult patients with minimal residual disease (MRD) positive acute lymphoblastic leukemia (ALL) demonstrate that a prolonged hematologic relapse-free survival was observed in patients treated with blinatumomab. A pivotal trial in adult MRD-positive ALL patients is scheduled to begin in Q3, 2010.  » Read more...
