The What If actor further added: It was really important as Ive worked with the Trevor Project for more than 10 years, and so I dont think I wouldve. Nevertheless, future clinical researches should focus on prospective, randomized, controlled trials in order to fully elucidate whether ABM/P-15 could be a feasible candidate for bone substitute material in orthopedic practices. i-Factor Putty Back to therapeutic area i-FACTOR Putty combines a unique anorganic bone mineral (ABM) and small peptide (P-15) that acts as an attachment factor for specific integrins on osteogenic cells. It is suggested that ABM/P-15 might be a good alternative biomaterial for bone implant fixation in this well-validated critical-size defect gap model in sheep. This study revealed that ABM/P-15 had significantly bone formation in concentric gap, and its enhancements on bone formation and implant fixation were at least as good as allograft. Adding HA/βTCP-PDLLA to ABM/P-15 did not significantly change these parameters. The ABM/P-15 group had similar shear mechanical properties on implant fixation as the allograft group. Bone formation and bone ingrowth to porous titanium implant were not significantly different among the four groups. Tissue volume fraction and thickness were significantly greater in the ABM/P-15 group than in the allograft group. ![]() Interestingly, the microarchitecture of the ABM/P-15 group was significantly different from the control group. Bone graft putty ABM, lecithin carrier (resorbable, biocompatible, semi-viscous lipid) P-15 synthetic peptide, calcium phosphate particles, porcine derived ABM anorganic bone matrix, along with bovine collagen carrier, P-15L Ongoing clinical trials. ![]() Significant bone formation and implant fixation could be observed in all four groups. A blinded, independent third party was utilised to assess safety, radiologic outcomes and neurologic outcomes. After nine weeks, bone-implant blocks were harvested and sectioned for micro-CT scanning, push-out test, and histomorphometry. that the P-15 Putty (Test arm) was non-inferior to the ‘gold standard’ autologous bone (Control arm) as determined by fusion rate, NDI scores, and neurological success. Titanium implants with 2-mm concentric gaps were inserted and the gaps were filled with one of the four materials: allograft a synthetic 15-amino acid cell-binding peptide coated hydroxyapatite (ABM/P-15) hydroxyapatite + βtricalciumphosphate+ Poly-Lactic-Acid (HA/βTCP-PDLLA) or ABM/P-15+HA/βTCP-PDLLA. A second type of human bone morphogenetic protein is rhBMP7, marketed in the United States as OP1. ![]() Cylindrical critical size defects were created at the distal femoral condyles bilaterally of eight female adult sheep.
