Condition breast cancer
Treatments high dose vitamin d3, placebo
Phase phase 2
Sponsor University of Kansas
Collaborator Novartis Pharmaceuticals
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.
