Vitamin D3 for Aromatase Inhibitor Induced Arthralgias
This trial is active, not recruiting.
|Treatments||high dose vitamin d3, placebo|
|Sponsor||University of Kansas|
|Start date||March 2009|
|End date||September 2011|
|Trial size||160 participants|
|Trial identifier||NCT00867217, 11548|
The primary purpose is to determine if high dose vitamin D3 reduces the incidence of musculoskeletal symptoms associated with the aromatase inhibitor letrozole in women with early stage breast cancer and low serum vitamin D levels. The primary hypothesis is that high dose vitamin D3 prevents the worsening of musculoskeletal symptoms when compared to a standard dose vitamin D3 treatment.
