Clinical Need

Trigeminal nerve injuries, often resulting from third molar extractions, implant placement, orthognathic surgery, and facial trauma, can cause lasting numbness or chronic neuropathic pain. While some injuries resolve spontaneously, many patients experience long-term deficits that significantly affect quality of life. Micro-suturing, the current standard for the repair of trigeminal nerve injuries, is technically demanding and can be inconsistent, with challenges in nerve alignment and spacing, and can also cause scar tissue that can impede axonal regeneration.

Solution

Tissure™ is a degradable, hydrogel and chitosan-based nerve connector that has the adhesion and mechanical strength required to eliminate the need for suture to reconnect peripheral nerves. The product adheres to wet nerve tissue and provides over five times the adhesion energy of cyanoacrylate while also providing flexibility to stretch through range of motion without damaging nerve healing.

Competitive Advantage

Current competitors in peripheral nerve repair offer largely undifferentiated collagen and polymer materials for connectors, conduits, and wraps. None of the competitors offer a suture-less alternative for a direct (non-connector) nerve repair and all of their product lines require suture to prevent migration of their product.

ITP Support

At the time of entry into the ITP program in 2023, the project already had a prototype and initial benchtop testing completed. At the end of the project period, design freeze and a non-GLP animal study are anticipated.

Achievements

  • Achieved sterile product and designed suitable packaging through moist heat sterilization while maintaining product integrity
  • Design freeze anticipated in 2025 following completion of non-GLP animal study
  • Ability to create a fully dried product that is rehydrated for 15 seconds prior to application

Regulatory Path

  • 510(k) anticipated; Pre-Submission meeting will be requested Q1 2026
  • Research and planning: market assessment, regulatory opinion, and potential corporate partnerships
  • Perform GLP rat sciatic nerve study and comparative benchtop studies with predicate device Q2 2026

Interviews with the Team

Robby Lane, MBA | Co-Founder & CEO, Amend Surgical

How did you get into/ what drew you to this field/ role?

For my current role it was somewhat serendipitous. I completed an expat assignment in 2014 and was asked during my transition back to the US by a former colleague to review a business plan for a start-up he was wanting to get off the ground. Several months later we jointly started Amend Surgical. My interest in the life sciences started in my undergraduate studies when a freshman advisor suggested that I should major in a course of study that I love. I selected Zoology and later combined that with a business degree. As a result of that advice and my continued interest I have worked in life sciences and medical devices for my entire career.

What excites you about your work?

I love product development. The challenge, the necessity for teamwork and the complexity makes product development unlike any other corporate discipline. In a start-up environment the development work is even more exciting as the risk-reward of so many critical decisions can have enormous consequences on the organization.

What advice would you give to those who are considering getting involved in translational research/ product development?

Translational research as a part of a small start-up company is a tremendous cross-functional learning opportunity. Small companies usually employ human resources that out of necessity work across most corporate functions. Our engineers work in R&D, QA and will periodically assist in the manufacturing of finished product. Additionally, at a start-up you will get visibility into a business operation and administration that is simply not available to new employees at larger companies. Small companies certainly bring risk but what better time to take on risk then at the start of your career.

If you weren’t in your current career, what other profession would you like to try?

I enjoy the creative process and if I could try another profession I would like to work as a Creative Director for a large, high profile advertising agency. I also enjoy training and teaching especially where the potential for life or career -changing influence is present. So, if could have a second choice I would also like to try to be a high school biology teacher.

Story

Amend Surgical – Innovations that Enhance Oral Wound Healing and Regeneration

Amend Surgical (Amend) began its journey into the DOC space after securing an exclusive license for a very promising new technology developed at the Wyss Institute at Harvard University (Wyss).


The license was focused on oral maxillofacial indications and finalized in 2020 (6 issued patents, 6 pending).The technology Amend licensed was developed to address the general medical need for strong adhesives that work over long periods of time in moist, mechanically demanding environments. Wyss used sophisticated chemistry – inspired by the tough and sticky mucus of the Dusky Arian Slug – to develop a biocompatible hydrogel and surgical glue that adheres to and protects wounds for weeks on wet, uneven surfaces, such as those found in the oral cavity.

The first product development effort Amend asked the MPWRM Resource Center (RC) to support was in 2021, with an initial focus on a non-resorbable tissue tape that can be used as an oral wound care “overlay” in multiple indications. Since successful wound closure and stable healing is key to predictable outcomes with most oral regenerative procedures, Amend Tissue Tape has the potential to directly impact the success of many of the soft and hard tissue regenerative treatments being performed today, and that the RC seeks to advance.

The technology Amend licensed from Wyss has the potential to be further differentiated as a resorbable “inlay” barrier used under tissue flaps to increase predictability and improve ease-of-use and outcomes in several DOC regenerative indications. Recently the company has also started to develop it as an oral nerve “wrap” to replace sutures and/or bridge gaps. In the future, this robust platform technology could also be loaded with drugs or biologics as a delivery vehicle to further enhance regenerative outcomes in especially challenging indications, or improve efficacy in many situations where local, more targeted delivery is desired.

This tremendous potential to significantly impact oral regenerative procedures and improve human health made Amend a strong candidate for RC support. This was especially true because they knew that they needed help and were clearly motived to tap into the expertise at the RC, beginning in the seed funding phase.

When Amend first approached the RC, they already had an existing small business with expertise in contract manufacturing for an orthopedic bone graft substitute they had been producing since 2015. They also had a strong business leader (Robby Lane) who knew how to raise capital and operate out of clean rooms under cGMP, FDA and state regulated processes. In addition, they had recently hired a dedicated engineer and technical leader, Jamie Shaikoski, to focus on advancing this very promising DOC technology.

The first thing Amend needed from the RC was a market assessment to confirm their assumptions about where this technology would have clinical value in the DOC space. They understood that their entire development program would be impacted by selecting the “right” indications. Through a series of in-depth interviews organized by the RC with key opinion leaders in this space, Amend got positive feedback but was quick to pivot to the indications where the clinical need and value was greatest.

In addition to tapping into the RC’s market knowledge, Amend benefited from multiple introductions to key potential partners and investors in the oral regenerative industry. They also valued the RC’s ability to provide technical and regulatory support, with a critical role in determining the best sterilization method for this new technology, which will be key to a successful FDA submission. Since the product value “in use” is related to how it handles, they also took advantage of the RC’s ability to organize surgical handling sessions with experienced clinicians who provided feedback on everything from technique to packaging, pricing, preferred configurations and even some brand elements the RC helped them develop. In general, Amend has worked closely with the RC to demonstrate efficacy to the FDA and engage clinicians who will drive clinical adoption.

The hope was that by working with the RC, Amend could significantly de-risk and fast track this promising new technology. This hope has been realized every step of the way with pre-clinicals and a successful FDA pre-submission meeting initiated in 2022. Based on the feedback they received, FDA clearance for the first indication as a non-resorbable oral wound dressing over periods of <24 hours is expected by Q1 2024. Preparations for the second 510(k) to allow for longer adhesion periods are already underway. In addition, the resorbable product (Amend Tissure) for barrier “inlay” indications will be ready for pre-clinical development by 2024.

The Market Assessment Core has been critical to Amend’s understanding of dental markets and connections with KOLs. They continue to provide significant input and have been vital for the commercialization of Amend Tissue Tape™.

In addition to the funding in 2021-2022 for development of Tissue Tape, Amend was recently awarded additional support by the RC to develop Tissure as a nerve “wrap” to avoid sutures and/or bridge gaps, with an initial focus on the trigeminal nerve in the oral and craniofacial space. This study and FDA submission will allow for general use of this technology in nerve indications, so even more patients can benefit. By initially helping the company develop an FDA strategy and clinical value proposition for Amend Tissue Tape, the RC is now able to support expansion of this technology platform into other indications – such as resorbable “inlay” barriers and nerve “wraps” – in the DOC space… and beyond.

Amend Surgical has made significant progress with support from the generous NIDCR grant that the RC has been charged with administering, shepherding them through (and over) the “Valley of Death” to clinical adoption and improved human health. Investors and potential industry partners are showing serious interest in working with Amend in the DOC space. Patients will be the ultimate beneficiaries.

This is one of many success stories we are proud to share!
