A Clinical Trial Investigating Iloprost as Medication to Improve Bone Healing in Patients With Proximal Humeral Fracture

Summary

The main objective of this study is to establish the safety as well as the efficacy of local insertion of Iloprost at the fracture site for bone healing of the proximal humeral fracture. The study will have two treatment groups and one control group. All patients will receive the standard of care procedure (reduction and angular stable (PHILOS) plate fixation). The two treatment groups will additionally be treated with two different Iloprost doses. Subjects will be assessed for study eligibility within 24h after admission (screening period). Eligible subjects will be assessed for baseline parameters on day 0. Within 96 hours of the study, subjects will undergo surgery, reduction, and angular stable (PHILOS) plate fixation. During the procedure, a catheter will be inserted in the fracture site of the treatment groups in order to deliver the Iloprost locally in the fracture site. The expected total duration of study participation for each subject comprises 52 weeks, among which 26 weeks include active study participation. At the study end, a telephone call with the subjects will be performed for safety assessment. Recruitment will be completed in approximately 18 months. Follow up visits following the surgical operation shall take place during weeks 3, 6, 12, and 26. The last follow-up will be a phone call during week 52 for the purpose of safety assessment.
