Multiple myeloma (MM) is a plasma cell cancer that develops in the skeleton
causing profound bone destruction and fractures. The bone disease is mediated by
increased osteoclastic bone resorption and suppressed bone formation.
Bisphosphonates used for treatment inhibit bone resorption and prevent bone loss
but fail to influence bone formation and do not replace lost bone, so patients
continue to fracture. Stimulating bone formation to increase bone mass and
fracture resistance is a priority; however, targeting tumor-derived modulators of
bone formation has had limited success. Sclerostin is an osteocyte-specific Wnt
antagonist that inhibits bone formation. We hypothesized that inhibiting
sclerostin would prevent development of bone disease and increase resistance to
fracture in MM. Sclerostin was expressed in osteocytes from bones from naive and
myeloma-bearing mice. In contrast, sclerostin was not expressed by plasma cells
from 630 patients with myeloma or 54 myeloma cell lines. Mice injected with
5TGM1-eGFP, 5T2MM, or MM1.S myeloma cells demonstrated significant bone loss,
which was associated with a decrease in fracture resistance in the vertebrae.
Treatment with anti-sclerostin antibody increased osteoblast numbers and bone
formation rate but did not inhibit bone resorption or reduce tumor burden.
Treatment with anti-sclerostin antibody prevented myeloma-induced bone loss,
reduced osteolytic bone lesions, and increased fracture resistance. Treatment
with anti-sclerostin antibody and zoledronic acid combined increased bone mass
and fracture resistance when compared with treatment with zoledronic acid alone.
This study defines a therapeutic strategy superior to the current standard of
care that will reduce fractures for patients with MM.
