A Study of XmAb®23104 in Subjects With Selected Advanced Solid Tumors (DUET-3)

NCT03752398

          5. All subjects in Part B (dose expansion) must have a tumor lesion that can be biopsied
             at acceptable risk (in the judgment of the Investigator) and must agree to both a
             fresh biopsy during screening and a second biopsy following treatment.

          6. Subjects have an ECOG performance status of 0-1.

        Exclusion Criteria:

             to an autoimmune condition that is treatable with hormone replacement therapy only;
             psoriasis, atopic dermatitis, or another autoimmune skin condition that is managed
             without systemic therapy; or arthritis that is managed without systemic therapy beyond
             oral acetaminophen and non-steroidal anti-inflammatory drugs)

         10. Receipt of an organ allograft

         11. History or evidence of any other clinically unstable/uncontrolled disorder, condition,
             or disease (including, but not limited to, cardiopulmonary, renal, metabolic,
             hematologic or psychiatric) other than their primary malignancy, that in the opinion
             of the Investigator would pose a risk to patient safety or interfere with study
             evaluations, procedures, or completion

         12. Treatment with antibiotics within 14 days prior to first dose of study drug
