Antibiotic Device for Osteomyelitis of the Extremities Pivotal Trial - Genex With Gentamicin.

Официальное название

A Multi-center, Single-arm, Historically Controlled Pivotal Trial, to Assess the Safety and Effectiveness of Genex G as Part of the Surgical Treatment of Osteomyelitis of the Extremities.

Обзор

The purpose of this trial is to determine if genex with gentamicin (genex G) an antibiotic loaded bone void filler, works to treat and is a safe option as part of the surgical treatment of osteomyelitis in the extremities.

Подробное описание

This trial is a multi-center, single arm, historically controlled, pivotal device study.

All participants diagnosed with osteomyelitis of the extremities (Cierny-Mader Classification grades I-IV) can be considered. All participants will undergo surgical debridement and will receive genex with gentamicin (genex G) antibiotic loaded bone void filler as part of the surgical treatment of osteomyelitis of the extremities. Participants will receive antibiotics per site specific requirements as clinically indicated. All participants will be followed up for 24 Months.

Критерии участия

Критерии включения

• Patient with osteomyelitis of the extremities, who have failed antibiotic therapy and are requiring surgical intervention (unresolved osteomyelitis), Cierny-Mader classification of osteomyelitis grades I-IV. Patients presenting with Cierny-Mader grades I-II will be required to have a defect created as part of debridement surgery
• Patients at least 18 years of age \*1
• Patient willing and able to provide written informed consent
• Patient geographically stable and able to comply with the required follow-up visits and testing schedule as assessed by the investigator
• Ability to achieve adequate surgical soft tissue coverage of the wound (primary tissue closure or surgical reconstruction including local and free soft tissue transfer)

• 1 Patients between 18 and 22 years of age require confirmation of skeletal maturity as validated by radiographs of the bone to be treated.

Критерии исключения

• Patients diagnosed with acute osteomyelitis
• Patients with Cierny-Mader grades I-II who are unable to have a defect created during debridement surgery
• Renal failure or documented chronic kidney disease with serum creatinine ≥3.5 mg/dL (309umol/L) or being treated with dialysis

• Pre-existing calcium metabolism disorder
• Women who are pregnant or breastfeeding or planning on becoming pregnant during the study (a pregnancy test will be done in women of childbearing potential at screening and on the day of surgery)
• History of hypersensitivity or contraindication to the investigational device or any of its ingredients (calcium phosphate, β-tricalcium phosphate, and aminoglycoside antibiotics)
• Participation in an investigational drug/device study (within the last 60 days) or prior enrolment to the ADOPT GG study
• Clinically significant or unstable medical or surgical condition that in the investigators opinion may preclude safe and complete study participation (for example patients medically unfit for surgery, general anesthesia, or any risk of significant blood loss resulting in significant risk to loss of life)
• Current untreated malignant neoplasm(s), or current treatment with radiation therapy or chemotherapy
• Current or recent history (within last 2 years) of active substance abuse (e.g. recreational drugs, narcotics, or alcohol) that meets DSM-5 severe criteria
