Lattice Biologics Launches AmnioVisc for Arthritic Joints

Lattice Biologics Ltd. ( TSX VENTURE: LBL) (OTCBB: BLVKF) (“Lattice Biologics” or the “Company“) is pleased to announce the launch of AmnioVisc™, a minimally processed amniotic fluid supplement for the treatment of joint pain associated with osteoarthritis (OA). Armed with six months of excellent results from a 275-patient study to assess its efficacy and safety, AmnioVisc™ is the most studied amnio viscosupplement to date. The Western Institutional Review Board (WIRB) controlled study demonstrates lasting safe pain relief and fewer adverse events than the current standard of care Hyaluronic Acid (HA) viscosupplements on the market.
AmnioVisc™ is a novel, targeted regenerative therapeutic that is delivering promising relief for patients suffering from all degrees of OA pain. This product is anticipated to significantly accelerate the company’s top line revenue growth.

The Growing Osteoarthritis (OA) Problem
OA is the most common joint disorder in the United States.¹ Approximately 10% of men and 13% of women aged 60 years or older demonstrate symptomatic knee OA.² OA is the most common reason for total hip and total knee replacement.³ The number of people affected with OA is only expected to increase due to the aging of the population and the obesity epidemic.⁴ This already common disease is increasing rapidly, suggesting it will continue to have a growing impact on healthcare and public health systems into the future.⁵
Sometimes called degenerative joint disease or degenerative arthritis, osteoarthritis is the most common chronic condition of the joints, affecting approximately 27 million Americans. OA can affect any joint, but it occurs most often in knees, hips, lower back and neck, small joints of the fingers and the bases of the thumb and big toe.⁶
Relief for OA Sufferers
Healthy joints rely on synovial fluid for lubrication to allow bones to glide against one another. In addition to providing nourishment to the cartilage cells, healthy synovial fluid also lubricates the articulating bony structures of the joint during low impact movement and shock absorption during high impact activities.
Synovial fluid breaks down in people with osteoarthritis, contributing to joint pain and stiffness. At every stage of the osteoarthritic disease process, the deterioration of synovial fluid can be experienced by the patient as pain, stiffness, and reduced joint function. One of the treatments for OA is viscosupplementation (injection of a lubricating fluid — which has most commonly been hyaluronic acid (HA) — into a joint).
The purpose of viscosupplements is to replenish the body’s naturally occurring synovial fluid with a substitute substance that recreates normal, healthy conditions as closely as possible and to break the cycle of synovial fluid deterioration. Viscosupplementation forms a protective layer around the inflamed articulating structures, covering micro-fractures and defects, and helping to restore the lubrication and protection of healthy synovial fluid.
Shortcomings in Current Therapies
Other osteoarthritis therapies currently available to patients offer inadequate relief and pose many serious side effects. Oral therapies (Acetaminophen, NSAIDs, COX II inhibitors, Duloxetine, and opioids) provide limited pain relief and present toxicity concerns to every part of the body, from the liver to the gastrointestinal and cardiovascular systems. Likewise, the pain relief benefits of intra-articular joint injections are similarly flawed, with the benefits of steroids disappearing after 2-4 weeks and the benefits of synthetic hyaluronic acid (HA) viscosupplements testing similar to placebo effects in controlled clinical studies.
As a result, the American Academy of Orthopedic Surgeons (2013) concluded that they “cannot recommend using Hyaluronic Acid for patients with symptomatic osteoarthritis of the knee.”⁷ This conclusion was a strong recommendation and was based on a metaanalysis of studies that failed to show a clinically clinically significant benefit from synthetic viscosupplements.
Introducing AmnioVisc™ – Proven Amnio Viscosupplementation for Osteoarthritis
Lattice Biologics is excited to launch an amnio viscosupplement for all joints. AmnioVisc™ is a 100% natural, minimally processed amniotic fluid supplement for the treatment of joint pain associated with OA. In what is the largest study ever conducted on an amnio viscosupplement, this product clearly outperformed traditional standard of care HA-based viscosupplementation, including: single-injection MONOVISC™ (sodium hyaluronate in a phosphate buffered saline solution); and 3-injection ORTHOVISC® and Synvisc-One® (both mixtures made from rooster comb-sourced hyaluronan).⁸
By contrast, AmnioVisc™ (human amniotic fluid as a new source of viscosupplementation) was shown to reduce pain, stiffness and difficulty at statistically significant levels for patients with knee osteoarthritis in a protocol-driven, WIRB controlled Registry of 275 patients documented so far in this protocol-driven study.⁸
Using the total WOMAC pain score, patients who received our amnio viscosupplement experienced the following results:

• At 30 days, 75% reported pain relief that was greater than 40%.
• Impressively, at 90 days, the number of patients reporting greater than 40% relief increased to nearly 80%.
• At 180 days (six months), two thirds of the patients (67%) were still reporting greater than 40% pain relief.

Study Efficacy Results8,9		Percent of Patients with greater than 40% Pain Improvement at 90 days (based on the total WOMAC pain score)
50%		ORTHOVISC®
62%		MONOVISC™
78%		AmnioVisc™
Study Efficacy Results8,10		Average Pain Reduction over baseline at 6 Months (using the WOMAC scale)
33.8%		Synvisc-One®
54.1%		AmnioVisc™

The AmnioVisc™ Advantage
There may be three reasons why Amniotic fluid is a more effective viscosupplement than either rooster comb derived HA or HA produced by fermentation technique:

1. It is 100% human HA. Hyaluronan from human amniotic fluid is immune privileged as it lacks MHC antigens (so it does not elicit an inflammatory immune response).
2. The components of amniotic fluid are very similar to healthy, native human synovial fluid. Both amniotic fluid and synovial fluid are ultrafiltrates from blood plasma and contain hyaluronan as well as phospholipids, cholesterol, growth factor proteins, cytokines and nearly the same inorganic compounds.
3. It restores correct pH levels. Human amniotic fluid has a pH level of about 7.0; the same as healthy synovial fluid. Osteoarthritis tends to create an acidic, toxic environment in the knee that causes pH levels to fall, typically, to about 3.5. Human amniotic viscosupplementation restores healthy pH levels which, in turn, create conditions that allow the patient’s own synovium to recover and — potentially — slow or even halt progression of the disease.

About the Study – “Amnio-Viscosupplementation: Review of the Safety and Efficacy of Amniotic Fluid in the Management of Joint Pain in Osteoarthritis”
In a protocol driven, single arm post-marketing Registry approved by the Western Institutional Review Board (Olympia, WA), patients with Kellgren Lawrence Grade 1-3 OA via radiologic examination were treated with a single injection of processed donated human amniotic fluid. Eligible patients were injected with 4cc of AmnioVisc™ minimally processed amniotic fluid into the affected knee. The study utilized VAS scores and WOMAC overall and Pain, Stiffness and Difficulty (function) sub-score scales as the primary efficacy endpoints as measured during office visits at baseline and at 30, 90 and 180 days.
