  • If the dosing of one or more of the chemotherapy components of a regimen must be reduced for toxicity, the modified version of the original regimen is not considered a new regimen
  • If one or more of the chemotherapy components of a regimen must be omitted for toxicity, the modified version of the original regimen is not considered a new regimen
  • If one of the chemotherapy components of a regimen must be replaced with another similar drug of the same therapeutic class, the modified version of the original regimen is not considered a new regimen; however, if a new component, dissimilar to any of the original components, is added to the regimen, the modified version is considered a new regimen
  • If chemotherapy is interrupted for surgery or radiotherapy and then continues with an unchanged schedule and components, treatment is considered as one regimen despite the interruption

• Prior treatment may include a taxane as per the following criteria:

• Major surgical procedures and open biopsies must be completed >= 28 days prior to randomization with documentation of adequate recovery from associated complications to grade =< 1
• Prior radiotherapy must be completed >= 14 days prior to randomization with documentation of adequate recovery from associated toxicities to grade =< 1
• Treatment with bisphosphonates or denosumab is allowed and recommended per the standard of care
• Therapeutic anticoagulation is allowed for patients on a stable dose of warfarin or low molecular weight heparin
• Measurable disease is defined as at least one lesion that can be accurately measured with the longest diameter as >= 1.0 cm by computed tomography (CT) scan or >= 1.0 cm with calipers by clinical examination; the exceptions to these criteria are pathologic lymph nodes, which must be >= 1.5 cm in the short axis when assessed by CT scans with slice thickness =< 0.5 cm
• Non-measurable lesions include the following: small lesions (longest diameter < 1.0 cm for all lesions other than pathologic lymph nodes, which are >= 1.0 cm and < 1.5 cm in the short axis), bone metastases, pleural effusions, pericardial effusions, ascites, inflammatory breast disease, leptomeningeal disease, lymphangitis pulmonis, lymphangitis cutis, and abdominal masses not followed by CT or magnetic resonance imaging (MRI)
