Abyrx Receives Additional FDA Clearances for MONTAGE® Settable, Resorbable Bone Putty as Bone Void Filler and Cranial Bone Cement

April 12, 2023


Abyrx, Inc. (, a leading biomaterial sciences company with a focus on therapeutic technologies for use during surgical procedures, today announced its receipt of additional United States Food and Drug Administration (FDA) clearances for the company’s MONTAGE® Settable, Resorbable Bone Putty as both a bone void filler and cranial bone cement. Used by surgeons across surgical specialties for a broad range of indications, MONTAGE is a hand-moldable, hardening putty that provides unique intraoperative utility and achieves bone-like properties within minutes of mixing and application. These new FDA clearances follow the highly successful clinical introduction of MONTAGE use on bleeding bone, which has garnered excellent physician feedback and surpassed 22,000 product uses with thousands of patients now multiple years removed from surgery.

“These expanded clearances for MONTAGE reflect its versatility, which is derived from its unique, self-setting and absorbable polymer. The product already has an impressive track record, with more than 22,000 uses since its initial FDA clearance, and we expect that these latest clearances will support its expanded use across more applications,” said John J. Pacifico, Founding President and Chief Executive Officer of Abyrx. “This important milestone is a testament to the dedicated efforts of Abyrx’s excellent scientific and regulatory teams, whose work is expanding the number and type of patients who have access to the benefits of MONTAGE.”

MONTAGE offers surgeons a new tool for previously unaddressed intra-operative challenges across multiple surgical specialties, replacing traditional settable calcium phosphate / sulfate and magnesium-based products which tend to be brittle. Unlike traditional settable calcium phosphate products, the hardening component of MONTAGE comprises a proprietary polymer designed in-house by Abyrx’s scientific leadership team. This novel polymer allows the product to be moldable and shapeable during the hardening process and machined using standard tools found in operating rooms.  Accordingly, surgeons are able to achieve precise placements to highly varying anatomy, and have reproducible performance even in the presence of heavy bleeding and irrigation. Following surgery, MONTAGE is designed to resorb during the bone remodeling process and be replaced by bone. Due to the fact that MONTAGE is cohesive, adheres to bone, and hardens, it may be used to help stabilize bone fragments and primary fixation hardware constructs during the procedure. The product can also be drilled and tapped, and hardware can be placed through it at any time during the setting process.

Abyrx continues to advance its technology platform while focusing on addressing the limitations of existing settable and non-settable bone putties. Building upon MONTAGE’s success, the company has introduced MONTAGE® FastSet, which reduces the product’s hardening time by approximately 50%, MONTAGE® XT, which doubles the product’s hardening time, MONTAGE® FLOWABLE, which is offered in a hand-held delivery system with a static mix tip to enhance its ease-of-use, and PERMATAGE™, a non-absorbable settable putty. Additional development efforts of its proprietary technology platform are underway for tissue fixation, intra-operative shaping of patient-specific implant devices, and site-specific delivery of growth factors, anti-infective agents, and local anesthetic drugs.
