Using your own cells with BonoFill-II to help rebuild and heal broken bones in the arms or legs

A Multicenter Study to Evaluate the Enhancement of Bone Regeneration and Healing in the Extremities by the Use of Autologous BonoFill-II

Phase1; Phase2 Interventional BonusBio Group Ltd · NCT03024008

This trial tests whether BonoFill-II, an autologous bone-regenerating graft made from your own cells, can help people with complex limb fractures or non-healing bone gaps heal and regain weight-bearing ability.

What this trial studies

This Phase 1/2 interventional trial implants an autologous cell-based graft (BonoFill-II) into deficient bone at sites of extra-articular comminuted fractures or extra-/intra-articular defects and non-unions that cannot self-regenerate. Participants will undergo surgical implantation of the graft prepared from their own cells and will be followed with clinical assessments and radiographic CT imaging. Safety endpoints include absence of heterotopic ossification, excessive bone formation, or local abnormalities, and efficacy endpoints include radiographic bone continuity and return of weight-bearing at 6 and 12 months. The trial is conducted at multiple hospital sites in Israel with scheduled follow-up visits for imaging and functional assessment.

Who should consider this trial

Good fit: Adults aged 18–80 with extra-articular comminuted long or short bone fractures or with extra- or intra-articular bone defects/gaps or non-unions that are incapable of self-regeneration are the intended candidates.

Not a fit: Patients with simple fractures treatable by a single definitive procedure, active local infection, uncontrolled diabetes (HbA1c > 8), severe organ failure, certain autoimmune diseases, current systemic steroid therapy, pregnancy/lactation, or more than three prior failed interventions at the site are unlikely to benefit or are ineligible.

Why it matters

Potential benefit: If successful, BonoFill-II could promote bone regeneration in difficult fractures or non-unions and reduce the need for additional surgeries while restoring the ability to bear weight.

How similar studies have performed: Previous clinical work with autologous cell grafts and bone morphogenetic proteins has shown promise for improving bone healing, but BonoFill-II represents a newer, less widely studied cell-based approach with limited prior clinical data.
