Phase II Randomised Trial of Cyclophosphamide and Dexamethasone in Combination With Ixazomib in Relapsed or Refractory Multiple Myeloma.


Brief description of study

This study evaluates a new treatment combination of ixazomib with cyclophosphamide and dexamethasone in relapsed or refractory multiple myeloma. Participants will either receive ixazomib with cyclophosphamide and dexamethasone or cyclophosphamide and dexamethasone alone.

Detailed Study Description

Cyclophosphamide and dexamethasone are very commonly used in the treatment of multiple myeloma and are often given with a third drug (e.g. thalidomide, lenalidomide or bortezomib). The combination of conventional and new drugs has provided benefits in both overall survival and progression free survival, however there are few treatments available for patients who have not responded well (refractory) to their previous treatment or who need further treatment because their myeloma has come back (relapsed). Thus there is a need for new agents for these patients.

The development of ixazomib provides the opportunity to increase anti-tumour activity against a wider range of tumour types. Early clinical trials data suggests it has anti-tumour activity in heavily pre-treated multiple myeloma patients with durable responses/disease control and is generally well tolerated.

Cyclophosphamide and dexamethasone are both predominantly used in treatment of multiple myeloma and for patients with relapsed or refractory multiple myelomas (RRMM), who have relapsed after bortezomib and lenalidomide. Therefore the evaluation of ixazomib in combination with cyclophosphamide and dexamethasone is the most valuable and practical option for patients.

The primary end point of this study is progression-free survival (PFS). Secondary end points include toxicity and safety.
