Abstract
Monitoring of drug therapies to prevent fractures is controversial. Measurement of bone turnover markers has the potential to identify those with a suboptimal response to fracture prevention medication within a few months of its commencement. However, given the imprecision of currently commercially available assays of bone turnover markers, many individual persons who are “suboptimal medication responders” are likely to be misclassified as “adequate responders” or vice versa, depending on the cut point chosen to define suboptimal and adequate response. Before bone turnover markers can be recommended for routine use in clinical practice to monitor fracture prevention therapies, three advances are needed: 1) bone marker assays with better precision; 2) research establishing optimal cut points of bone marker levels to distinguish “suboptimal responders” from “adequate responders”; and 3) research establishing the incremental fracture reduction benefit from clinical interventions for “suboptimal responders” identified from bone marker measurements.

This paper re-analyzes data from the FIT trial to make the point that in-person variability of serum bone markers (albeit with older assays for P1NP) is greater than the differences in bone marker change in those on alendronate versus placebo; thus, there is the potential for significant misclassification of “suboptimal responders” as “robust responders” and vice versa.
