BURLINGTON, Mass.--(BUSINESS WIRE)-- Bone Biologics Corporation (NASDAQ: BBLG), a developer of orthobiologic products for spine fusion markets, today issued the following letter to stockholders from its President and Chief Executive Officer, Jeffrey Frelick.

To My Fellow Stockholders:

I am delighted to update you on Bone Biologics’ development work with NELL-1 over the past year and to review our expected milestones over the coming months in anticipation of commencing our first-in-human pivotal study in 2023. As a reminder, NELL-1 is a recombinant human protein that we licensed through a technology transfer agreement with the UCLA Technology Development Group (UCLA TDG) for worldwide applications. NELL-1 combined with demineralized bone matrix (DBM) forms our product candidate, NB1.

NELL-1 has unique properties that suggest it will be ideal in treating spinal fusion, trauma, osteoporosis and other bone-related indications, and may be especially useful among “hard healers.” This potential lies in its ability to provide rapid, specific and guided control over bone regeneration. We are optimistic that NB1 may provide an important alternative to a vexing clinical problem by improving the safety profile of an osteopromotive orthobiologic.

There is a large and established opportunity for NB1 with an estimated global market of $3 billion annually just for bone graft substitutes in spine fusion for products such as growth factors, DBM, synthetic materials, stem cells and allografts. This is the market Bone Biologics intends to address. Longer term, additional market opportunities await NB1 including the $11 billion annual market for treating osteoporosis and the $8 billion annual market for treating trauma patients.

A great deal of development work has been undertaken with NELL-1 in preparation for our first pilot clinical trial in Australia. Publications support NELL-1’s mechanism of action and its potential for better bone formation, as preclinical animal data have been both extensive and compelling. Of particular importance is a study that evaluated the efficacy of NB1 as a novel bone graft material for interbody spine fusion in sheep, a phylogenetically advanced animal with spine fusion similarities to humans. That study found that NB1 safely and effectively promoted spine fusion.

With compelling preclinical data, we have moved forward with important activities to prepare for our human pilot study. Thus far in 2022, we entered into an agreement with MTF Biologics for supplying DBM as a carrier in our combination product. MTF Biologics, a highly regarded industry innovator, is a global nonprofit organization that provides one of the orthopedic industry’s largest portfolios of allograft tissue. MTF Biologics’ DBM will comprise half of our NB1 product.

Earlier this year we also engaged a contract development manufacturing organization (CDMO) that offers a global site network from process development to recombinant protein manufacturing. Because NELL-1 is a recombinant human protein that will be utilized in humans, it must be manufactured in specialized facilities, therefore engaging a CDMO was an important preparatory step.

Updated Agreement with UCLA

In 2006 we entered into an agreement with UCLA Technology Development Group to license NELL-1. This agreement is the foundation for Bone Biologics.

We most recently modified that agreement in May 2022 to enable us to preserve available capital and resources to develop our product. Under the modification, UCLA TDG will defer payment of the diligence fee until we (or any of our sublicensees) sell any product in accordance with the revised payment schedule.

Recent Equity Financing

We recently raised gross proceeds of $5.1 million in an underwritten public offering of units of common stock and warrants. We expect to use the net proceeds to fund our planned clinical trials, maintain and extend our patent portfolio, retain contract research organizations, and for working capital and other general corporate purposes. Importantly, these funds will allow us to begin our 30-patient pilot study with NB1 next year.

Expectations through 2023

As we look to the remainder of 2022, we are working toward several value-creating events:

• In preparation for the cGMP manufacturing run for product that will be used in our human clinical study, assays will be developed that characterize NELL-1 (including the potency assay, which quantitates the bone formation activity), a Master Cell Bank will be developed and scaling activities will be performed.
• We are building a quality system to meet the conditions of Essential Principles required by the Australian regulatory authorities prior to the initiation of human studies.
• We will also engage another CDMO that will perform fill/finish functions. This activity is required to ensure sterility, which is another requirement prior to human implantation.

Looking to 2023, we plan to commence a 30-patient clinical trial in Australia. This will be a multicenter, prospective, randomized pilot study evaluating the safety and preliminary effectiveness of NB1 in subjects with degenerative disc disease undergoing transforaminal lumbar interbody fusion.

As currently envisioned, the study will evaluate two concentrations of NB1 relative to the autograft control. The primary endpoints will include fusion success at 12 and 24 months after surgery, and change from the baseline Oswestry Disability Index, which is the Gold Standard tool to measure a patient’s permanent functional disability.

The Need for NELL-1 in a Compelling Market

The scientific basis for developing NB1 is the potential for increased safety and for better fusion rates. Spine fusion is a commonly performed surgical procedure in the treatment of numerous spinal diagnoses including degenerative disc disease, spinal stenosis, spondylolisthesis and other spinal deformities. A bony fusion is essential for restoring segmental stability, preventing or correcting deformity and improving long-term outcomes. Lumbar intervertebral fusion is achieved by creating an environment that’s conducive to the formation of a continuous osseous bridge across the involved spinal segments.

We are optimistic that spinal fusion patients will benefit from our solution to the problem of hard-to-heal bones, and we are very excited about the potential to help these patients as we advance NB1 along the development pathway. We believe our effort will be well-rewarded not only by patients, but also by caregivers and Bone Biologics stockholders. I extend thanks to all of our constituents for their ongoing support.

Sincerely,

Jeffrey Frelick
Chief Executive Officer
