BioInvent International AB of Sweden has started a Phase 1 study in the US of its monoclonal antibody, BI-505, in patients with advanced multiple myeloma. The drug has been granted orphan status by both the US Food and Drug Administration and the European Medicines Agency. Patients in the trial will be treated with intravenous doses of the drug every other week for a 28-day period with the possibility of extending the treatment until the condition deteriorates again. BI-505 binds to the adhesion protein, ICAM-1, which is over-expressed in several tumours but is not usually expressed in normal tissue. It is being developed to treat multiple myelomas that express this protein. Multiple myeloma is a cancer of the plasma cells.
