Bone Substitutes clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Pre-market Study to Evaluate Safety and Performance of GreenBone Implant (Long Bone Study)

Start date: January 22, 2019
Phase: N/A
Study type: Interventional

Multi-center, international, prospective, open-label, single-arm, first-in-human clinical investigation. The Patients enrolled in this clinical investigation will undergo a scheduled surgery for the treatment of long bone defects up to 6 cm using GreenBone Implant. After the surgery, the Patients will be monitored at pre-scheduled visits up to 12 months. Adverse events, pain, quality of life and functional parameters, as well as X-ray and CT scan, will be evaluated at scheduled follow-up visits. An independent Data Safety Monitoring Board (DSMB) will review the safety reports at regular intervals and Serious Adverse Events (SAE) as soon as reported, to protect Patients participating in the study. The initial phase of the study contemplates the treatment of bone defects up to 3 cm. An adaptive interim analysis will be performed when the first 7 Patients will have completed the 6-month follow-up visit. The DSMB will review the results of the interim analysis with respect to the primary endpoint (safety), and provide one of the following recommendations to the Sponsor: a) to stop the study for unacceptable frequency and severity of adverse events or b) to continue the study up to 25 Patients recruited and to include at least 5 Patients with a longer bone defect (> 3 cm up to 6 cm).
