3. Must have had a relapse or progressive disease (PD) after having received 2 or more prior lines of systemic therapy. Note: A line of therapy is defined as 1 or more cycles of a planned treatment program; this may consist of 1 or more planned cycles of single-agent therapy or combination therapy, as well as a sequence of treatments administered in a planned manner. For example, a planned treatment approach of induction therapy followed by autologous stem cell transplantation (SCT), followed by maintenance is considered 1 line of therapy. Typically each line of therapy is separated by PD.
