Atorvastatin (Lipitor) to Prevent Bone Pain

Osteoporosis Clinical Trial

Official title: Use of Atorvastatin (Lipitor) to Prevent Bone Pain Following Infusion of Pamidronate or Zoledronic Acid

Status Completed

Clinical Trial Summary

In the proposed randomized double blind cross-over placebo controlled study, the researchers intend to investigate if Atorvastatin (FDA approved statin for children) can be used to alleviate the symptom of bone pain (acute phase reaction) that is commonly associated with initial doses of pamidronate or zoledronic acid, and also the mechanism that underlies this proposed beneficial effect of Atorvastatin. The primary outcome studied will be alleviation of bone pain by Atorvastatin compared to placebo by visual analogue pain scale in children treated with pamidronate or zoledronic acid. The secondary outcome investigated will be changes in blood count and γδT cell count, C-reactive protein (CRP) and cytokine levels of interleukin 6 (IL-6), tumor necrosis factor-alpha (TNF-α) and gamma interferon (γ-IFN) following treatment with Atorvastatin compared to placebo.

Clinical Trial Description

The proposed study is a double blind cross-over placebo controlled randomized clinical study that would be conducted in the Metabolic Bone Clinic of The Children's Mercy Hospital. This is a pilot study and a more comprehensive study will be designed only if the results from this pilot study are significant. In our proposed double blind cross-over placebo controlled pilot study we will have a total of 12 children who will receive either placebo or Atorvastatin in a randomized cross-over design. The pilot study with a sample of 12 in a cross-over trial will provide reasonably stable estimates even though it is unlikely to provide statistical significance on its own but will help plan further large scale studies. ;
