Bone Healing During Ninlaro Exposure (BONE)

Thomas Lund

Status and phase: Completed; Phase 2

Conditions: Multiple Myeloma

Treatments: Drug: Ixazomib

Study type: Interventional

Funder types: Other

Identifiers

NCT04028115

Details and patient eligibility

About

The primary purpose of this study is to investigate if treatment with Ixazomib in multiple myeloma (MM) can strengthen the bones, thus making it resilient to future fractures. Ixazomib will be given at a time point when the disease is in a stable phase, decreasing the likelihood that the potential bone anabolic effect will be abrogated by catabolic effect of active MM. In order to be included in the study, the patient must have treatment demanding MM, and the disease must have been brought into at least partial remission with chemotherapy before inclusion. Moreover, the patient must have pathological bone structure on low dose CT due to the pre-existing disease.
