Efficacy and Safety of Ixazomib and Dexamethasone Refractory Autoimmune Cytopenia

NCT03965624 · Status: WITHDRAWN · Phase: PHASE2 · Type: INTERVENTIONAL

Summary

Some patients with antibody-mediated autoimmune hematological diseases (warm autoimmune hemolytic anemia (wAIHA), cold agglutinin disease (cAIHA) and immune thrombocytopenia (ITP)) shows no or only minor and transient response to therapy despite several treatment-lines. Such patients are more likely to have a severe disease, with a higher morbidity and mortality.

Hypothesis Effective depletion of autoreactive plasma cells might be the key for a curative approach of these diseases. Therefore, there is a rationale for using proteasome inhibitors (PIs) in these refractory patients.

The rationale is that non-tumoral autoreactive plasma cells are rapidly targeted by proteasome inhibitors. It led us to propose a short course of dexamethasone and ixazomib (5 cycles), to evaluate the safety/efficacy of this innovative strategy of treatment.

Method Prospective interventional uncontrolled single arm open study evaluating the rate of patients achieving 5 cycles of ixazomib and dexamethasone without severe toxicity and response on therapy.

DRUG

Ninlaro

Oral ixazomib will be given on days 1, 8, 15 of a 28-day cycle, the investigator will start with first test dose levels of ixazomib of 3 mg and process with dose escalation, in case of non-response and no severe adverse events at cycle 1 (see above) or de-escalation in case of response and severe adverse events.
