Micromet has presented promising new data from two clinical trials with its lead BiTE® antibody, blinatumomab, at the 53rd American Society of Hematology (ASH) Annual Meeting in San Diego, CA. 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. The compound is being developed for the treatment of leukemia and B cell lymhoma.

The data show that Micromet’s blinatumomab more than doubled the complete remission rate produced by current standard therapies used to treat adult patients with relapsed or refractory B-precursor acute lymphoblastic leukemia (ALL).  » Read more...

The human immune system is one of the body’s most powerful weapons to combat cancer, and therefore a lot of companies are working to activate it against tumors, writes Siegfried Hofmann in Handelsblatt this week. As an example, he features the BiTE antibodies developed by Micromet, Inc. These BiTE antibodies bind to T cells and subsequently to specific tumor antigens on cancer cells. Thereby, the T cells are activated and start destroying the tumor cells. The first drug candidate is in late-stage clinical development to treat Leukemia, Hofmann writes. The article is also being featured in the internet version of Wirtschaftswoche.  » Read more...

Micromet, Inc. (NASDAQ: MITI) 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.

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.  » Read more...

- 75% of patients achieved a complete remission, with no evidence of remaining leukemic cells in blood or bone marrow -
– Data add to a growing body of clinical evidence demonstrating blinatumomab’s potential to be used across the course of the disease -

Data to be presented tomorrow at the 16th Annual Meeting of the European Hematology Association (EHA) in London, UK, show that Micromet’s blinatumomab produced a high complete remission rate in adult patients with acute lymphoblastic leukemia (ALL) who had relapsed following treatment with standard therapy. ¹ Blinatumomab is the most advanced of a new class of agents called BiTE® antibodies, designed to harness the body’s T cells to kill cancer cells.  » Read more...
