Rituximab is the first anti-cancer antibody approved by the FDA for the treatment of B-cell lymphoma. However, its efficacy remains variable and often modest. Some patients are initially unresponsive to rituximab or later develop resistance to it, and require alternative therapies. ⋯ Interestingly, TGLA also shows significant ADCC activity. Immunotherapeutic studies further show that TGLA is far more effective in delaying tumor growth than rituximab. These findings suggest that the ADCC-enhanced anti-CD20 antibody TGLA might be an alternative therapeutic agent for B-cell lymphoma.
