A previously irradiated lesion cannot be considered a target lesion. Radiographic disease assessment can be performed up to 28 days prior to the first dose of trial treatment. It is acceptable for the measurable lesion to be planned for removal at surgery. CT reported RECIST assessments are acceptable at screening for participants with chest metastases.
