Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To determine the efficacy of a treatment combining daratumumab and ibrutinib in a poor risk population of relapsed CLL patients with TP53 dysfunction. ;Secondary Objective: To determine the safety profile of daratumumab in combination with ibrutinib in CLL patients;Primary end point(s): CR rate at 12 months;Timepoint(s) of evaluation of this end point: M12 | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): • Frequency and severity of tumor lysis syndrome during and after the 2 first infusions of daratumumab • Type, frequency, severity and relationship to study treatment of adverse events. Incidence of Treatment Emergent Adverse Event (TEAE), Serious Adverse Event (SAE) and laboratory abnormalities using National Cancer Institute (NCI) common toxicity criteria (CCTAE V4) • OR rate, PR rate, PR with lymphocytosis rate • MRD assessement • PFS and OS • Duration of response • Time to next treatment • Cumulative rate of Richter’s syndrome • CD38 expression in CLL cells before treatment and on ibrutinib before daratumumab initiation • Ancillary studies ;Timepoint(s) of evaluation of this end point: until the last patient has definitively stopped study treatment | — |
