Nova Vita Laboratory24 enrolled

Overview

The below summarizes relevant information for investigator(s) to consider the use of Allogenic Human Amniotic Fluid product in a clinical protocol detailing study design and conduct for a phase I/II randomized, double-blinded, placebo-controlled clinical trial to evaluate the safety and potential efficacy of NANOVAE injected intra-articularly in patients suffering from knee osteoarthritis. The IB will be reviewed annually and amended when further information becomes available. Osteoarthritis (OA) is a degenerative disease of the joints that affects millions of people worldwide, yet its exact causes are not fully understood. Middle-aged to elderly individuals are often the most impacted by OA, which primarily affects the knee, hip, spine, and joints in the fingers. Among these, knee osteoarthritis (KOA) is the most common form, causing pain, stiffness, and reduced functionality, and it is a major contributor to chronic bone and muscle pain. It is also a leading cause of disability in adults who are not living in institutions. Treatment for KOA is challenging due to its resistance to medications, procedures, and surgeries. The primary objective is to alleviate pain and enhance overall function. However, since there is currently no cure for OA, the need for an effective therapy remains urgent. Healthcare professionals often encounter patients whose pain may result from an inflammatory response triggered by injury or disease. Research suggests that regenerative medicine, utilizing techniques like stem cells, platelet-rich plasma (PRP), amniotic fluid, and cytokine modulation, holds promise for treating KOA. OA is associated with an increase in pro-inflammatory substances such as interleukin (IL)-1, IL-6, tumor necrosis factor-alpha (TNF-α), matrix metalloproteinases (MMPs), nitric oxide (NO), reactive oxygen species (ROS), and cytokine-inducible cyclooxygenase-2 (COX-2). These inflammatory agents affect various cell types within the affected joints, including chondrocytes, osteoblasts, osteoclasts, synoviocytes, and macrophages. Some miRNAs, which are downregulated in OA, have been identified as protective factors. For example, miR-130 helps regulate TNF-α levels, while miR-149 controls several inflammatory cytokines such as IL-1, IL-6, and TNF-α. The breakdown of the cartilage matrix is a key characteristic of OA. MMP-13, a member of the MMP family, plays a significant role in degrading the collagen network during OA development. Several miRNAs, including miR-27b, miR-27a, miR-148a, miR-320, miR-127-5p, and miR-411, are downregulated in OA and target the mRNA of this proteinase. It is important to note that a single miRNA can regulate multiple target genes associated with OA progression. For instance, miR-105 and miR-148, both downregulated in OA, target genes such as Runx2, ADAMTS4, ADAMTS5, ADAMTS7, ADAMTS12, MMP-13, and COL10, implying their potential protective roles. Several studies have shown a link between certain miRNAs, aging, and the progression of OA. For example, miR-320c is downregulated in aging OA samples and regulates ADAMTS5, suggesting that this miRNA may serve as a protective factor by enhancing chondrogenesis.

The investigational product being assessed in this trial is called NANOVAE, which is a biologic derived from human amniotic fluid (HAF) that is allogenic and acellular. HAF contains a wide range of growth factors, cytokines, chemokines, and extracellular vesicles/nanoparticles obtained from perinatal tissue. These components contribute to the regenerative potential of HAF and make it a promising option for regenerative medicine applications, particularly in knee osteoarthritis (KOA). Studies have demonstrated that the extracellular vesicles found in HAF, including exosomes, have the ability to promote chondrogenesis and reduce inflammation, which are crucial processes in reversing the progression of KOA. Additionally, these vesicles have shown to stimulate cartilage regeneration, addressing the impaired cartilage repair typically observed in OA. Therefore, the administration of HAF-derived products has the potential to slow down the degenerative process and promote cartilage repair in patients with KOA. The growth factors and cytokines present in HAF may also help alleviate the inflammatory response observed in the knee joint, a characteristic feature of KOA. These anti-inflammatory properties, combined with the regenerative capabilities of the extracellular vesicles, make HAF an appealing candidate for the treatment of KOA. Numerous clinical studies registered under ClinicalTrials.gov have provided evidence of the safety and effectiveness of HAF products in joint therapies. The use of HAF for treating OA holds immense potential due to its array of growth factors, anti-inflammatory mediators, and medicinal signaling cells, which continue to undergo rapid advancements. In a non-FDA review study, a double-blinded controlled trial was conducted comparing the treatment of OA with freshly collected amniotic fluid and steroids. The results revealed a significant improvement in the Visual Analog Scale (VAS) after three months of treatment, with continuous improvement in VAS after six months in both groups. However, the group receiving freshly collected amniotic fluid exhibited greater improvement. These findings strongly support the potential of this novel HAF therapy for advanced OA, as it proved to be superior and longer lasting compared to conventional therapies commonly practiced. Further research, both in terms of basic science and clinical investigations, is warranted to gain a better understanding of the anti-inflammatory properties of amniotic fluid and determine the most efficacious amniotic fluid product for symptomatic OA. NANOVAE is a filtered form of HAF (human amniotic fluid) that utilizes the wide range of nanoparticles, cytokines, and growth factors present in the fluid, which play vital roles in fetal development and maturation. HAF is a rich source of collagen substrates, growth factors, amino acids, polyamines, lipids, carbohydrates, cytokines, and extracellular matrix molecules like hyaluronic acid and fibronectin, as well as cells. These components greatly contribute to tissue protection and repair. Extensive research has demonstrated the antimicrobial, immunomodulatory, and growth-promoting properties of HAF. The antimicrobial, antiviral, and antifungal effects of HAF have been established through the identification of various components such as lysozyme, peroxidase, transferrin, β-lysin, immunoglobulins, and zinc-peptide complexes within the fluid. The immunomodulatory functions of HAF have been observed in its ability to suppress alloreactive responses and downregulate Th1 and Th2 cytokines. NANOVAE's extracellular vesicle (EV) fraction consists of several cytokines, chemokines, and growth factors that are associated with functions such as host defense, anti-inflammatory response, angiogenesis, and cartilage repair. The concentration of nanoparticles in the final product has been consistently demonstrated through nanoparticle analysis using the ZetaView Quatt nanoparticle analyzer. This analysis reveals a range of particles, with an average mode particle size of 96.4 nM, which aligns with the expected size of exosomes ranging between 50-200 nm in diameter. Objectives: Primary Objective: To demonstrate the safety of NANOVAE administered intraarticular in subjects with KOA by measuring the incidence of any of the following treatment-emergent adverse events (TE-AEs) and treatment-emergent serious adverse events (TE-SAEs) within the first 30 days of injection: Occurrence of adverse events related to the therapy within 30 days of NANOVAE treatment. Life-threatening event (e.g., stroke or non-fatal pulmonary embolism). Event resulting in persistent or significant disability/incapacity. Event resulting in death. Secondary Objective: To demonstrate the potential efficacy of NANOVAE by measuring the following clinical response changes from baseline to 12 months after injection. Time Frame: Month 1, 3, 6, and 12 after infusions: Change in single leg stance test. Change in "Timed Up and Go" test to assess fall risk. Change in Western Ontario and McMaster Universities Osteoarthritis (WOMAC) Index (five items for pain, two for stiffness, and seventeen for function). Change in range of motion, assessed by goniometer measurements. Change in serum and/or synovial biomarkers between the timepoints of Day 0 and the 3-month visit. Design and Investigational Plan: A total of 24 subjects meeting all inclusion/exclusion criteria will be divided into two groups. Group 1 will be an open-label lead-in phase. Group 2 will be a randomized, double-blinded, placebo-controlled cohort. Group 1 will receive one dose of 2ml of NANOVAE, and Group 2, in a randomized and double-blinded fashion, will receive two doses of 2ml NANOVAE. Neither the patients nor the researchers will know who is getting the placebo and who is getting the NANOVAE; only the product manufacturing staff will be unblinded. The ratio of placebo to NANOVAE is 1:1 for a total of 16 subjects in Group 2. Only the knee with the more severe symptoms of OA will be treated. The allogenic-HAF will be obtained from healthy donors and manufactured by the Nova Vita Laboratories processing lab. Group 1 (Open Label): A total of eight subjects will be treated to assess safety prior to enrolling Group 2. Safety will be assessed at seven-day intervals for the 8 subjects in Group 1, staggered by 5 days after receiving the dose of NANOVAE. Dose: 2 mL of NANOVAE on Day 0 containing 1.0 x 10¹¹ to 9.0 x 10¹¹ particles/ml. Product will be administered directly without any dilution. After these 8 subjects complete the 5-day safety assessment, the safety report will be presented to the DSMB with representative data to determine the safety status of receiving one dose of NANOVAE. Once the treatment of Group 1 has been determined to be safe, the enrollment of Group 2 will begin. Group 2 (Randomized, double-blinded placebo control): A total of sixteen subjects will be randomized to either receive two doses of NANOVAE via intraarticular injections or receive two doses of a placebo. Dose: 2 mL of NANOVAE or placebo on Day 0 and Day 15, containing 1 x 10¹¹ particles/ml. The ratio is 1:1 for a total of 16 subjects in Group 2. Product will be administered directly without any dilution.

Secondary Outcomes

Change in Single Leg Stance Test

The Single Leg Stance Test will measure the ability of participants to balance on one leg for a specified duration. The test will be performed with eyes open and closed, and the time participants can maintain balance on a single leg without support will be recorded in seconds. The minimum value is 0 seconds, indicating inability to balance, and there is no fixed maximum value. Higher values indicate a better outcome (i.e., improved balance).
