Targeting the RANK/RANKL/OPG pathway for treatment of osteoporosis in Cystic Fibrosis
Study ID: STU 052018-007
Summary
Main Study up to 100 subjects, both non-CF volunteers and Cystic Fibrosis (CF) patients, will participate in a single study visit that will include a DeXa scan, micro CT, and blood collection. Denosumab (Prolia) Sub study This is a single center open label pilot study to determine safety and benefit of use of denosumab (Prolia) in individuals with CF who have osteoporosis. The aim is to determine if bone density as measured by DeXa improves over 1 year period of time after treatment. approximately 10 adult subjects with CF who participated in the main study and have results indicating bone disease, who will be prescribed denosumab (Prolia) either through standard of care or research will participate in the sub study. Denosumab (Prolia) will be administered subcutaneously 1 time every 6 months for a total of 2 doses.
