Inclusion Criteria: * Patients with cytologically confirmed and documented de novo, secondary or therapy-related AML, excluding acute promyelocytic leukaemia with relapsed or refractory disease without established alternative therapy. Or patients with measurable confirmed Multiple Myeloma (IMWG) with relapsed or refractory disease who have previously received at least three lines of treatment and without established alternative therapy. Or patients with histologically and measurable confirmed Non Hodgkin Lymphoma defined as Diffuse Large B cell Lymphoma (DLBCL), Follicular Lymphoma (FL), Mantle Cell Lymphoma (MCL), Marginal Zone Lymphoma (MZL), High-Grade B cell Lymphoma with relapsed or refractory disease who have received at least two lines of therapy (including rituximab) and without established alternative therapy.
