NCT05517265

Brief Summary

The goal of CICERO is to investigate the clinical outcome with a particular focus on prospective data on safety using acalabrutinib (+/- obinutuzumab) in CLL patients receiving co-medication with DOACs (edoxaban, rivaroxaban, dabigatran, apixaban) irrespective of treatment line.

Outcome Measures

Primary Outcomes (1)

  • Incidence proportion of patients with major bleeding event according to Schulman et al.

    Bleeding event is defined as major according to Schulmann et al., if it is fatal (contributes to death) and/or symptomatic in a critical area or organ (such as intracranial, intraspinal, intraocular, retroperitoneal, intraarticular or pericardial, or intramuscular with compartment syndrome) and/or causing a decrease in hemoglobin of 2 g/dL (1.24 mmol/l) or more or requires a transfusion of 2 or more units of whole blood or red blood cells. Incidence proportion (cumulative incidence) is calculated as the number of patients with bleeding event while on treatment (+30 days safety follow-up), divided by the number of patients in the full analysis population.

    Baseline until end of acalabrutinib treatment (+ 30 days safety follow-up); up to 41 months

Secondary Outcomes (26)

  • Incidence proportion of clinically relevant non-major (CRNM) bleeding events

    Baseline, up to 41 months

  • Major (according to Schulman et al.) and/or CRNM bleeding events.

    Baseline, up to 41 months

  • Any bleeding event.

    Baseline, up to 41 months

  • Incidence proportion of major bleeding according to Ghia et al.

    Baseline, up to 41 months

  • Time to first Occurrence of major bleeding events

    Baseline, up to 41 months

  • +21 more secondary outcomes
