Primary Outcome Measures

Name	Time	Method
Main Objective: The main purpose is to evaluate feasibility and safety of daratumumab subcutaneous injections in patients with moderate to severe ME/CFS. ;Secondary Objective: We will also collect efficacy data. ;Primary end point(s): The primary outcome measures are safety and tolerability as measured by treatment-emergent adverse events > CTCAE grade 1. <br><br>;Timepoint(s) of evaluation of this end point: Adverse events will be recorded bi-weekly during treatment period (weeks 12 to 20) and monthly until the end of study (52 weeks), and a total evaluation performed at end of study. <br>A safety review will be performed after two patients have completed treatment.

Secondary Outcome Measures
