Oxis Biotech Discusses Its Immunotherapeutic Development Strategy

TAMPA, Fla., April 1, 2015 /PRNewswire/ -- Oxis Biotech, Inc. (OXIS), a wholly owned subsidiary of Oxis International, Inc. [OTC: OXIS] discussed during its March 31, 2015 conference call with shareholders, analysts and other interested parties certain aspects of its immunotherapeutic development strategy.  During the teleconference, Anthony J. Cataldo, Chairman and Chief Executive Officer stated that Oxis Biotech is focused on developing immunotherapies for the treatment of triple-negative breast cancer, and multiple myeloma and associated osteolytic lesions which are significant unmet medical needs. 

Oxis Biotech is pursing the development of targeted immunotherapies with its partner, MultiCell Immunotherapeutics (MCIT).  MCIT's proprietary antibody-drug conjugate (ADC) platform technology is based on unique multivalent, cleavable linkers that allow tethered drugs to be released intracellularly or extracellularly upon binding of the antibody to the target cell.  Additionally, the MCIT linkers are designed to attach multiple drugs per targeting antibody, and to release the drugs in their original form without modification of the drug.  An example of an FDA-approved ADC is Seattle Genetics' ADCETRIS® (brentuximab vedotin) for the treatment of Hodgkin lymphoma and anaplastic large cell lymphoma (ALCL).

In additional to developing traditional ADCs, Oxis Biotech is also developing bispecific immune cell engagers, a class of monoclonal antibodies that direct a person's immune system to attack cancer cells.  More specifically, bispecific immune cell engagers consist of the part of the monoclonal antibody which recognizes an immune cell such as a cytotoxic T-cell, and the part of a different monoclonal antibody which recognizes the cancer cell.  When administered as a therapeutic, the bispecific immune cell engager brings cytotoxic T-cells in contact with the target cancer cell where the cytotoxic T-cell kills the cancer cell.  An example of a bispecific immune cell engager is Amgen's recent FDA-approved drug BLINCYTO® (blinatumomab) for the treatment of acute lymphoblastic leukemia (ALL).
