NCIt definition : A preparation of autologous peripheral blood lymphocytes (PBLs) harvested from chronic
lymphocytic leukemia (CLL) patients previously treated with the Brutons' tyrosine
kinase (BTK) inhibitor ibrutinib with potential immunostimulating and antineoplastic
activities. Upon intravenous administration, IOV-2001 generates an enhanced cytotoxic
T-cell response against autologous leukemic B-cells in patients who have relapsed
during treatment with ibrutinib. IOV-2001 is mostly comprised of T-cells of which
the majority are of the effector memory phenotype which augments the specificity of
the immune response.;
