Summary
This study evaluates the safety and efficacy of carfilzomib used in combination with thalidomide and dexamethasone in patients with relapsed AL amyloidosis. The trial begins with a dose escalation phase, in which the maximum tolerated and recommended dose will be determined. The trial will then open into an expansion phase in which the combination efficacy is assessed.
