510(k) Submission with FDA Accelerated for Early Second Half of 2024

AUSTIN, TX / ACCESSWIRE / May 1, 2024 / Monogram Orthopaedics Inc. (NASDAQ:MGRM) ("Monogram" or the "Company"), an AI-driven robotics company focused on improving human health with an initial focus on orthopedic surgery, today provided an update related to the regulatory and commercialization path for its mBôs surgical system following its meeting with the U.S. Food and Drug Administration (the "FDA").

On April 19, 2024, Monogram received written feedback from the FDA regarding the Company's Q1 2023 pre-submission request. Subsequently, Monogram conducted a teleconference meeting with the FDA on April 24, 2024, to discuss the written feedback further and obtain feedback on the Monogram mBôs™ TKA System verification test plan, including a proposed clinical trial protocol on an outside the U.S. (OUS) target population. Management believes the feedback was comprehensive and will be advantageous for preparing a successful 510(k) submission to obtain clearance.

The Company shared with the FDA various test protocols essential for establishing the safety and effectiveness of the Monogram mBôs™ TKA System and a synopsis of its proposed OUS clinical investigation plan.

Based on the feedback, management assesses that: 1) the proposed testing plan generally appears acceptable to address the technical differences identified with the proposed predicate device, and 2) for the active (also autonomous) embodiment of its product, a clinical testing plan that includes approximately 100 knee surgeries conducted on an OUS population at three sites with three months of follow-up should generally be sufficient for evaluating the safety and effectiveness of the Monogram mBôs™ TKA System. Notably, on March 21st, the Company announced that it had modified the Monogram mBôs™ TKA System to reduce the likelihood of an FDA clinical data request with its submission.

In their written response the FDA indicated they support a least burdensome approach to acquiring clinical data. Management anticipates running an OUS clinical trial could save the Company significant cost and time. Currently, management estimates the cost to run an OUS clinical trial as proposed to be approximately $1.5M. The Company plans to run a clinical trial to support post-launch marketing irrespective of whether it will be needed for obtaining regulatory clearance with the FDA.

Updated Key Objectives

• Given the favorable FDA feedback for using OUS clinical data, Monogram management anticipates establishing an ongoing OUS clinical strategy to support its innovation strategy. Access to an extensive OUS surgeon and hospital network and an accommodative FDA posture towards OUS data could accelerate the development and commercialization of its technology pipeline, including mVision, its novel tracking solution that aims to eliminate point based registration and tracking with large fiducial based arrays.
• The Company recently announced that the Verification and Validation testing will be largely complete in Q2 of 2024 and anticipates a 510(k) submission to follow in the second half of 2024.

The Company's plan to aggressively accelerate 510(k) submission for its mBôs surgical system with design modifications that management believes reduce the risk of a clinical trial request is on track. The Verification and Validation testing is underway, and the Company has largely completed various mandated packaging, biocompatibility, sterilization, and cleaning validations. Except for ongoing IEC testing, most tests that rely on outside vendors are on track or largely complete. For IEC testing, the Company has largely completed various mandated radiated emissions and immunity testing. The paperwork reviews are largely complete, and various electromechanical and safety tests are starting soon. The Company believes the system will perform favorably in outstanding IEC testing based on completed internal testing and various design considerations. One of the most demanding test protocols is the Human Factors Evaluation and Design Validation, which requires at least 15 surgeons to use the system in a simulated surgery. The Company is using much of the data from these labs to test other aspects of the system, such as system accuracy. The Company has completed six simulated surgeries, with a significant remaining portion planned in May 2024.

Monogram has engaged MCRA, a US-based Contract Research Organization (CRO), to support its regulatory strategy for submission.

"Our team has been actively executing extensive, highly rigorous internal and external testing while diligently incorporating feedback from the FDA," said Ben Sexson, Chief Executive Officer of Monogram. "We continue to expect verification and validation to be largely complete in H1 2024, with a planned FDA 510(k) submission in H2 2024. We believe an OUS clinical data strategy could become valuable for ongoing research, development, and commercialization efforts."

Dave McGurl, Vice President, Regulatory Affairs at MCRA, commented: "Monogram's engagements with the FDA have been highly constructive, with the Company having incorporated the FDA's feedback into the mBôs™ TKA System design. After numerous communications with the FDA and extensive clarity provided by the Monogram team, the Company should be set up for success with the 510(k) submission to the FDA for clearance. The Company has taken patient safety extremely seriously, which is apparent in numerous aspects of the design. The Company's verification and validation plan appears to satisfy all the FDA's stated concerns, and the FDA has been supportive of Monogram following a least burdensome approach to clinical data procurement. We look forward to continuing to support Monogram through its submission and clearance."

Upcoming 2024 Milestones

• Largely complete mBôs system verification and validation - H1 2024
• Submit 510(k) application to FDA - H2 2024
• Commence OUS live-patient surgery trials - H2 2024
• Expanded international relationships

About Monogram Orthopaedics

Monogram Orthopaedics (NASDAQ:MGRM) is working to develop a product solution architecture with the long-term goal of enabling patient-optimized orthopedic implants at scale by linking 3D printing and robotics with advanced pre-operative imaging. The Company has a robotic system that can autonomously execute optimized paths for high-precision insertion of implants in synthetic bone specimens. Monogram intends to produce and market robotic surgical equipment and related software, orthopedic implants, tissue ablation tools, navigation consumables, and other miscellaneous instrumentation necessary for reconstructive joint replacement procedures. The Company has not yet made 510(k) premarket notification submissions or obtained 510(k) clearances for its robotic products. FDA approval is required to market these products, and the Company has not obtained FDA approval for any of its robotic products, and it cannot estimate the timing or assure the ability, to obtain such clearances.

Monogram Orthopaedics is working to advance the way orthopedic surgery is done. Our system is being developed to combine personalized knee implants with precision robotic surgical assistants to hopefully give patients a better-fitting knee replacement with minimally invasive surgery. One hundred thousand knee replacements failing each year in a $19.4B market represents an enormous opportunity for us.
