CD70 (Cluster of Differentiation 70) is a ligand for CD27.

Clinical significance

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.[1]

Drug development

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.[2]

Vorsetuzumab mafodotin is a CD70-targeted antibody-drug conjugate that started clinical trials for renal cell carcinoma.[3]
