Kolosis BIO and MTF Biologics Announce Launch of Kore Fiber™

Salt Lake City, Utah, February 1, 2021

Kolosis BIO, LLC (Kolosis) announced today, in collaboration with MTF Biologics (MTF), the market release of Kore Fiber™, an exclusively processed demineralized cortical fiber allograft for Kolosis.

Dr. Anthony Russo, of Montana Orthopedics in Butte, Montana stated, “The aseptic processing methods coupled with the fantastic handling characteristics of Kore provide an excellent option for bone grafting. I am a believer in the power of MTF allografts to help accelerate bone healing for my patients.” Dr. Russo was the first surgeon nationwide to implant Kore and incorporate the tissue into his practice.

Kolosis President and Chief Executive Officer Collin Begley noted, “We are extremely excited to launch Kore Fiber with MTF Biologics. Based on our commercial experience in bone grafting technologies, especially with MTF processed tissues, we see the enormous potential of this tissue form to capture significant market share in the cortical fiber space. Kore is an aseptically-processed, 100% cortical bone matrix with tremendous handling characteristics. Extensive pre-launch testing confirms Kore’s dynamic spectrum of growth factors; attributes which are essential for promoting and accelerating bone healing. We could not be more excited to add Kore Fiber to our exclusive MTF portfolio of bone graft tissues, which also includes Prime HD®, a pre-hydrated cortical graft.”

Chief Executive Officer of the MTF Biologics Joe Yaccarino commented, “Our long-term commercial experience with the team at Kolosis has proven to be extremely successful for MTF, and we’re proud to launch Kore as an extraordinary graft option to tissue recipients.”

The release of Kore Fiber includes the launch into both spinal and orthopedic applications and is available in four different sizes of moldable fiber and three sizes of strips.
