ONKOS SURGICAL® and 3D Systems Team To Advance Personalized Surgical Oncology Solutions

PARSIPPANY, NJ, March 6, 2018 -Onkos Surgical, Inc. Announced today that it signed a 4-year agreement with 3D Systems (NYSE:DDD) to advance the delivery of personalized surgical solutions and help improve patient outcomes. The agreement provides Onkos Surgical priority access to 3D Systems’ VSP® (Virtual Surgical Planning) Orthopedic product line for surgical planning, as well as 3D printed anatomical models. Additionally, the companies will collaborate on next-generation 510(k) clearances for 3D printed implants and instruments for tumor reconstruction.

Through this partnership, the companies aim to advance the delivery of personalized surgical solutions to help improve outcomes for patients with tumors and lesions occurring in the pelvis and long bones (i.e., the large bones found in the arms and legs) associated with musculoskeletal cancers. The combination of VSP and 3D printing allows surgeons to preoperatively plan a surgical procedure, as well as design surgical tools and implants for each patient’s unique case.

Established by 3D systems, VSP technology received FDA market clearance for the cranio-maxillofacial region as a service-based approach to personalized surgery, combining expertise in medical imaging, surgical simulation and 3D printing. The surgeon initiates the process, bringing their clinical knowledge and desired surgical plan to an online web meeting with a 3D systems biomedical engineer to simulate and plan the surgical procedure. The outcome is a digital plan that is transferred to the operating room via accurate 3D printed patient-specific models, guides and templates.

“We are delighted to announce this partnership with 3D Systems, a true visionary and leader in medical device 3D printing and surgical planning,” said Patrick Treacy, co-founder and chief executive officer, Onkos Surgical. “As an early stage investor in Onkos, they understand the criticality of our connection to the customer, the unique challenges these surgeons and patients face and the tremendous opportunity we have to make a difference for these patients while building a high value and scalable business.”

Onkos surgical was founded in 2015 to deliver high quality implants and instruments that meet the unique needs of musculoskeletal tumor patients. The company quickly embraced 3D printing as a technology that could address the particular needs of both the cancer patient, and the cancer surgeon. Onkos surgical realized the profound impact they could make if they combined personalized 3D printed medical devices and instrumentation with patient-specific surgical simulation.

“When we launched our Precision Oncology initiative at MSTS 2017 in Denver, it was met with great enthusiasm from the surgeon community,” said Sean Curry, senior vice president of commercial operations, Onkos Surgical. “The relationship with 3D Systems enhances our capabilities with product bundles and patient-specific solutions that will deliver on our promise of bringing focus and dedication to this space.”

“3D Systems is pleased to partner with Onkos Surgical delivering adaptive tools designed to provide insights, processes and outcomes for musculoskeletal oncology cases,” said Kevin McAlea, executive vice president, general manager, Metals and Healthcare, 3D Systems. “The combination of VSP and 3D printing provides an advantage for surgeons to personalize the surgical plan, instruments and implants for each unique case.”

According to the NIH – National Cancer Institute (cancer.gov), there were 3,260 new primary bone cancer cases reported in 2017. In addition to chemotherapy and radiation, two common surgical options for musculoskeletal cancer patients are amputation and limb salvage. Through limb salvage, the surgeon removes the cancer and some healthy tissue with the goal of leaving the limb largely intact. The section of bone that was removed can be replaced either with a bone graft from the patient or another person, or with an internal prosthesis (i.e., implants) made of metal and other materials.

ONKOS SURGICAL® Announces Major Milestone with First Patient Entered in the Onkos Registry

PARSIPPANY, NJ, March 8, 2018 -Onkos Surgical, Inc., a specialty medtech company dedicated to advancing innovation for the surgical oncology market, announced today that Dr. Steven Gitelis and Rush University has entered the first patient in the Surgical Oncology Registry Team (SORT™) or Onkos’s Registry. SORT™ is a multicenter, cloud based, HIPAA compliant platform designed to prospectively collect functional, psychosocial and oncological outcomes.

“This is a major milestone for Onkos and the musculoskeletal oncology community of surgeons and patients. When we started our company, we made a commitment that we would place a large investment in collecting prospective outcomes in this space,” said Patrick Treacy CEO and co-founder of Onkos Surgical. “SORT™ is a cloud-based platform that will allow surgeons to collect prospective data and collaborate with other institutions to drive larger data sets. We are the first and only company to invest in a registry of this kind and we believe this database will allow clinicians to answer meaningful questions that may lead to improved patient outcomes.”

Steven Gitelis, MD, Onkos Surgical Chief Medical Officer and Surgeon in Chief and Director, Section of Orthopedic Oncology at Rush University said, “This is an unprecedented opportunity for my musculoskeletal oncology colleagues to collaborate in a way that will answer important questions. The Onkos Registry provides a research platform that will enable individual institutions to prospectively collect their own data while partnering with other leading institutions around the country to answer questions that will potentially impact how we treat patients in the future. In the past, small data sets have impacted the ability to truly change the paradigm of patient care. This registry has the potential to change that.”

“We have several leading cancer institutions around the country who are interested in this platform,” said Jerry D’Alessio, Onkos VP of R&D and Advanced Engineering. We spent a tremendous amount of time perfecting the protocol and analytical tools to enable surgeons to prospectively assess functional, psychosocial and oncologic outcomes. The cloud-based platform allows the surgeons to design prospective studies and enables patients to participate in the analysis of their outcomes. We are excited to expand this registry over the coming year.”

ONKOS SURGICAL® Tackles Significant Clinical Challenge: Aseptic Loosening

Aseptic loosening of endoprostheses continues to be a substantial clinical challenge for orthopedic oncologists and the patients they treat1. While improvements in implant design have helped, surgeons continue to search for new solutions to solve for aseptic loosening in a patient population with compromised healing potential2. Fortunately, there have been technological advances such as additive manufacturing (3D printing) and methods to apply hydroxyapatite (HA) to three-dimensional pore structures that may help to address this clinical challenge.

A recent publication by Mumith et al. Suggests there are opportunities to obtain improved fixation for endoprostheses with the use of stems designed to incorporate porous metal extracortical collars. This is significant, considering a large number of patients with distal femoral and proximal tibial endoprostheses require a revision due to implant loosening3. The results of this research provided two key insights for future implant designs to potentially address this challenge. First, the authors found that optimal tissue ingrowth is heavily dependent on pore size. Second, they noted that HA coatings, when deposited on a porous metal implant in a manner such that the implant remains porous, can have hydrophilic properties. This allows the implant to absorb and deliver blood or other biological fluids to the endogenous, healthy bone at the implant interface. The research concluded that a collar design with a specific porosity to maximize bone ingrowth, coupled with a HA coating applied in this certain way, may promote extracortical bone bridging1.

Onkos Surgical is currently focused on three distinct clinical areas of innovation aligned with the most common failure modes of limb salvage implants: 1) Infection, 2) soft tissue management and 3) aseptic loosening1. We have invested heavily in developing experience and expertise in 3D printing and application of HA. We believe, combined with our singular focus on providing solutions for musculoskeletal oncologists and their patients, this provides us with the ability to develop new implant designs to address aseptic loosening.

We have also partnered with clinicians at leading cancer institutions to guide our development initiatives. We are specifically interested in understanding the clinical factors that impact patient outcomes and the nuances of the surgical workflow to optimize or efficiency. In a recent meeting with Shervin Oskouei, MD, Assistant Professor of Orthopedic Surgery at Emory University School of Medicine, we discussed his thoughts on aseptic loosening and implant design.

Dr. Oskouei, can you share your thoughts on the challenges associated with aseptic loosening in your patient population?

“Similar to the results in arthroplasty patients, implants used in oncology applications have a high failure rate due to aseptic loosening. Especially as patients survive longer, I suspect we will continue to see a rise in failures from loosening.”

What are some implant design factors that you believe are important in minimizing this complication?

“The reduction of polyethylene wear debris and inability of polyethylene debris to gain access to the canal of the long bone in oncology implants is crucial. Similar to the findings in the Mumith study, there is merit in providing a solution where the collars will be able to be matched to the patients’ cross sectional diameter for ideal fit and bone ingrowth. I think we need to look to biologic fixation of our implants to bone as an ideal way to reduce aseptic loosening including press-fit stems to allow a biologic fixation with constant remodeling of the implant-bone interface.”

At Onkos, we are currently focusing development efforts on a family of stems with HA coating to address the clinical challenge of loosening (figure 1). We believe this may have the potential to provide an optimal environment for bone and soft tissue attachment, improve extracortical fixation, and reduce the incidence of implant revisions due to loosening.

ONKOS SURGICAL® Featured in MedTech Strategist

Key points

• The musculoskeletal oncology market has long been a niche of a niche, woefully under-served by large orthopedic companies, which often forces surgeons to improvise the tools and implants they need to treat patients.

• Launched just over two years ago, Onkos Surgical is building a company focused exclusively on this segment, basing its business on a deep relationship with surgeons who have historically felt ignored by product companies.

• The company has been able to move quickly and efficiently by embracing a strategy it calls “specialty medtech” as well as a novel approach to manufacturing using 3D printing. It is also building through partnerships, including one with 3D pioneer 3D Systems.

• Onkos is already thinking of ways it can expand its business, but perhaps its greatest challenge: proving to this often-neglected customer base that it’s different from other orthopedic companies and that its commitment to the field is real.
