Company News: Micromet Initiates Pivotal Study of Lead Compound Blinatumomab

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.

If successful, the study could  serve as the basis for filing for approval.

A further Phase II study initiated today is designed to evaluate the efficacy, safety and tolerability of blinatumomab in 20 adult patients suffering from B-precursor acute lymphoblastic leukemia (ALL) who are resistant or intolerant to standard chemotherapy.

Details can be found in the press releases describing the BLAST trial and the refractory ALL trial.
