The CD70 protein is expressed on highly activated lymphocytes (like in T- and B-cell lymphomas). It is therefore suggested that anti-CD70 antibodies might be a possible treatment for CD70 positive lymphomas as normal lymphocytes do not express a lot of CD70.
ARGX-110 is a CD70-specific antibody that is currently under investigation for the treatment of hematological malignancies. It is being developed by the Belgian company arGEN-X. In december 2013 a first part of a phase 1b trial was completed. In january 2014 a safety and efficacy phase of the study started.
