The primary purpose of this study is to determine whether the investigational drug XmAb541 is safe and well tolerated, and to determine an optimal and safe dose(s) for further study. The study will also evaluate the effect of XmAb541 on tumor outcomes.
Phase 1 trials primarily test safety and dosing in a small number of participants (typically 20–100). Results do not yet speak to efficacy. FDA approval is typically many years away from this stage.
Currently recruiting: the trial is enrolling patients. A data readout is not expected until after enrollment closes and the follow-up period is complete.
Xencor Inc (XNCR) is the sponsoring company for this trial. BiotechSign currently grades this company D (41/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
