BONESUPPORT announces that a pre-clinical study evaluating the in-vivo release kinetics of radio-labelled bone morphogenic protein (rhBMP-2) and zoledronic acid (ZA) from CERAMENT BONE VOID FILLER (BVF) was presented at the European Orthopaedic Research Society (EORS) in Munich on 15th September.
The presentation was given by Mr Deepak Raina, Department of Orthopaedics, Medical Faculty, Lund University, Sweden. In his presentation, Mr Raina, outlined data showing that CERAMENT BVF achieved co-delivery of both rhBMP-2 and ZA in-vivo measured over a period of four weeks. After 4 weeks, CERAMENT BVF had eluted 57% of rhBMP-2 and 23% of ZA. This is an important finding since the constant availability of rhBMP-2 over a long period could give osteo-inductive properties to CERAMENT BVF while at the same time the presence of ZA locally prevents bone resorption.
These data suggest that by using CERAMENT BVF to elute BMPs it could be possible to overcome the problems of local delivery of BMPs using currently available approaches.
Another pre-clinical study, which demonstrated in vivo that CERAMENT loaded with a combination of rhBMP-2 and ZA in very low doses was able to quantitatively and qualitatively generate a high amount of mineralized bone volume was covered in a paper published in Nature Scientific Reports (Raina, D et al). The study showed that the mineralized volume was significantly higher when CERAMENT was combined with rhBMP-2 and ZA compared to CERAMENT in combination with just rhBMP-2.
Mr Deepak Raina, commenting on his presentation said: “The important findings that we presented at EORS suggest that by capitalizing on CERAMENT BVF’s elution characteristics it could be possible to overcome the current problems associated with the local delivery of BMP to promote bone growth. The growing body of data that our research group is generating with CERAMENT BVF provides greater confidence that this novel approach could lead to a commercially available product able to enhance bone growth.”
Richard Davies, CEO of BONESUPPORT, commented: “We are pleased that these in vivo data on CERAMENT BVF combined with bone morphogenic protein and zoledronic acid have been presented at this prestigious scientific conference. These data provide further support to our product pipeline strategy which is focused on developing new CERAMENT products that are able to enhance bone growth.”
