Lund, Sweden, 19:40 CET, 09 09 21 – BONESUPPORT™, an emerging leader in orthobiologics for the management of bone injuries, today announced inconclusive results for the company’s Investigational Device Exemption (IDE) study; FORTIFY. The primary safety endpoint for CERAMENT G was met.

The FORTIFY study was initiated in 2017 with the purpose to evaluate the ability of CERAMENT G to improve the treatment outcomes for patients with open tibia fractures G-A II-IIIB. Last patients follow up took place in June 2021.

The drop-out rate, defined as difference between enrolled and completed patients, was 29% and lost to follow up was 18% and 9 % for the treatment group and control group respectively.

Subjects drop out is generally high with all trauma studies. In the FORTIFY study, with a majority of the patient final follow-ups taking place during the COVID pandemic, the drop-out rate has been very high with only 143 qualified subjects of 201 enrolled for the composite efficacy endpoint at 12 months. The very high drop-out rate has led to FORTIFY not qualifying to the requirements of a PMA application.

The primary composite end point success was 64% in the treatment group (CERAMENT G) and 66% in the control group; non-significant difference. None of the secondary parameters were conclusive.

The severe trauma that patients with open tibia fractures G-A II-IIIB have been exposed to is known by high variability in bone healing, infection incidence and soft tissue recovery. Nevertheless, the failure to reach conclusion on the study data is both surprising and disappointing.

BONESUPPORT will work with FDA to review possible regulatory pathways for CERAMENT G for the indication trauma.
