Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This is a Phase 1, multiple dose, ascending dose escalation study; to define a MTD/RD and regimen consisting of a first "priming" dose and escalated subsequent doses of XmAb18087; to describe safety and tolerability; to assess PK and immunogenicity; and to preliminarily assess anti-tumor activity of XmAb18087 in subjects with advanced NET or GIST.
