Effects of dichloromethylene diphosphonate on skeletal mobilization of calcium in multiple myeloma.

Abstract
Dichloromethylene diphosphonate (Cl2MDP), an inhibitor of oestoclast activity, was evaluated for its ability to decrease the excessive mobilization of skeletal calcium that complicates multiple myeloma. Ten patients with active myeloma, wide-spread bone disease, and hypercalciuria were studied in a double-blind, placebo-controlled, crossover-designed trial in which they took Cl2MDP for eight weeks and placebos for eight weeks. Two patients died during the placebo phase; of eight patients who received Cl2MDP, seven had rapid, sustained, and highly significant (P less than 0.001) decreases in urinary excretion of calcium. Six also had significant decreases in hydroxyproline excretion, and five reported lessening of skeletal pain. On patient did not respond. Although the patients received concurrent chemotherapy during the study, concentrations of myeloma proteins actually increased or decreased only slightly, indicating the declines in hypercalciuria resulted from Cl2MDP and not from improvement in the underlying disease. We conclude that Cl2MDP is a potentially useful inhibitor of osteoclast-mediated bone erosion in multiple myeloma.
