Novadip Biosciences SA has announced positive data from its Phase 1/2 clinical trial evaluating the safety and clinical activity of NVD-003 in patients with severe lower limb bone non-union (BNU) from trauma.
In this study, NVD-003, an autologous tissue engineered product generated from the patients’ own adipose stem cells, was applied in nine patients with bone non-union of the lower limb who had previously undergone several surgical procedures; in one case, a patient had undergone 14 previous procedures. The U.S. Food and Drug Administration (FDA) defines a non-union as a fracture that is at least nine months old and has not shown any signs of healing for three consecutive months despite surgical intervention.
Highlights from the clinical study results include:
“This Phase 1 study has shown that NVD-003 represents a convincing step forward in the development of an optimized bone graft substitute in terms of applicability and outcome,” said Professor Torsten Gerich, M.D., Ph.D., chief of Trauma Service at the Centre Hospitalier de Luxembourg and principal investigator of the trial. “NVD-003 is a very promising product with the potential to outperform autologous bone harvesting and other less potent bone graft substitutes such as DBM, ceramics and growth factors and prevent their accompanying comorbidities. Further investigations in larger scale clinical studies will be needed to confirm these promising results.”
The study’s primary endpoint was safety of NVD‑003 in adult patients with recalcitrant lower limb non-union. Secondary endpoints included:
Novadip is developing NVD-003, an autologous therapy derived from adipose stem cells as a potential single treatment to save limbs and restore mobility in patients with congenital pseudarthrosis of the tibia (CPT), a rare pediatric bone condition.
Novadip has enrolled and treated the first patient in a Phase 1b/2a clinical trial to study NVD-003 in CPT patients between 2 and 8 years old in the United States and Europe. The trial will enroll a total of four patients and the results will be used to inform the clinical and regulatory pathway for NVD-003 in patients with CPT.
“We will share the results of this BNU study with the FDA as part of IND discussions to support registration for NVD-003 for the treatment of CPT,” Novadip Biosciences CEO/Co-Founder Denis Dufrane, M.D., Ph.D., said.
NVD-003 has received orphan drug and rare pediatric disease designations from the FDA. If approved by the FDA, Novadip is eligible to receive a priority review voucher that could provide more than $100 million revenue.
The company is also developing an allogeneic “off-the-shelf” therapeutic, NVD-X3, to provide accelerated, durable bone union in common orthopedic conditions such as spinal fusion and non-healing fractures. Both investigational products are derived from Novadip’s 3M³ platform, a three-dimensional, extracellular matrix that utilizes adipose-derived stem cells to deliver highly specific growth factors and miRNAs to mimic the physiology of natural tissue healing.
“The results from the BNU study also support and de-risk the development of NVD-X3, which, as an allogeneic therapy, has a favorable cost profile that can allow broad distribution and expanded access for patients undergoing spinal fusion or suffering from recalcitrant non-healing fractures.” Dr. Dufrane added.
The risk of bone non-union following fracture is greater than 50% across all bones due to fracture severity, co-morbidities (diabetes, obesity, smoking and other conditions) and medication use. Additionally, more than 600,000 spine fusion procedures are performed annually.
Novadip Biosciences SA is a clinical stage company developing best in class tissue regeneration therapies to elevate the standard of care for critical size bone defects, common orthopedic conditions, and cancer. Its 3M³ tissue regeneration technology platform has the potential to generate an array of product candidates to address hard and soft tissue reconstruction for patients with limited or no treatment options. Co-Founded in 2013 Novadip is headquartered in Mont Saint-Guibert, Belgium.

Highlights from the clinical study results include:
- No safety issues or implant associated complications were observed.
- Two-year clinical and radiological follow up confirmed NVD-003 achieved stable and irreversible bone healing in patients with recalcitrant bone non-union in the lower limb following failure of conventional surgical and bone engraftment treatments.
- Rapid bone formation was confirmed at three months post-implantation in all patients.
- Clinical healing with weight bearing and walking at six months post-implantation.
- Complete (100%) success for the NVD-003’s manufacturing capabilities from autologous adipose stem cells.

The study’s primary endpoint was safety of NVD‑003 in adult patients with recalcitrant lower limb non-union. Secondary endpoints included:
- Healing efficacy of NVD‑003 by radiographic assessments (via X-ray at discharge, six weeks, three months, six months, 12 months, 24 months and via CT-scan at six months, 12 months, 24 months)
- Healing efficacy of NVD‑003 by clinical assessments (weight bearing ability, pain at palpation)
- Assessment of patient reported outcomes such as pain, quality of life and overall treatment effect (e.g., brief pain inventory, EuroQol-5D, OTE)
- Assessment of local complication rate after graft implantation
