aap Implantate AG ("aap" or the "Company") announces that with the recent approval for an amendment to the clinical trial plan by the BfArM and the Ethics Committee, an important step towards accelerating the human clinical trial of the antibacterial silver coating technology developed by aap could be implemented. The changes to the clinical trial plan were deemed necessary by the Company because it has become apparent during the conduction of the trial to date that the originally envisaged number of patients with fractures exclusively of the distal tibia cannot be achieved within a reasonable period of time.

The two crucial changes at a glance concern:

  • Removal of double blinding: The previous situation with an unblinded surgeon who then cannot perform follow-up visits has proven difficult to implement in practice. Unblinding the entire study team and the sponsor will simplify planning and patient care. Furthermore, this allows for smaller study teams and more flexible handling in case of vacation or illness of the investigators.
  • Adjustment of target fracture: Due to the significantly higher incidence of fractures of the fibula, a faster inclusion of a significant number of patients is expected. In addition, it will facilitate the planning and execution of the surgeries, which will reduce the workload on the investigators.

Following approval by the BfArM and the Ethics Committee, the Company has started production of a sufficient number of study implants for the adapted target fracture. Based on the changes to the clinical trial plan, aap plans to complete the number of patients to be included under the human clinical trial in mid-2024, after which the mandatory follow-up year will begin.

All previous applications of silver-coated implants in the context of individual healing trials showed very good healing processes and no evidence of infections could be detected. These overall very good results are a positive indication for the ongoing clinical human study.

With its antibacterial silver coating technology, aap is addressing one of the greatest and yet inadequately solved challenges in traumatology: the reduction of Surgical Site Infections (SSI). Surgical site infections represent a major burden both for the patients affected and for global healthcare systems. Antibiotic-resistant bacteria pose a particular threat. In its annual report on the state of research to overcome antibiotic resistance, the WHO recently found that some of the world's most dangerous bacteria have developed resistance to known agents.[1] Moreover, according to the WHO, nearly all antibiotics currently in development work little better than existing agents. aap's innovative antibacterial silver coating technology represents an alternative solution in the fight against bacterial infections that is not based on antibiotics and therefore offers enormous market potential. As a platform technology, the technology has a broad range of applications and can be used not only in traumatology but also in other areas of orthopedics as well as in cardiology, dentistry, or medical instruments.

The conduction of the clinical study is funded by the German Federal Ministry of Education and Research ("BMBF"). The grant awarded to the company (grant numbers 13GW0313A+B, 13GW0449A+B) is part of the BMBF's field of action "Healthcare Industry in the Health Research Framework Program". According to the BMBF, projects on the topic of "Transferring medical technology solutions into patient care - proving clinical evidence without delay" are being funded.
