Organogenesis Achieves Primary Endpoint in Phase 3 Clinical Trial of ReNu® for Knee Osteoarthritis

May 2, 2024

• Statistically significant (p=0.0177) reduction in knee pain at six months

• Statistically significant (p<0.0001) maintenance of function at six months

• Transformational opportunity for Organogenesis to enter large and growing pain management market with innovative therapy

• Will address critical unmet medical need for all knee OA patients, including the most severe, if approved


CANTON, Mass., May 02, 2024 (GLOBE NEWSWIRE) -- Organogenesis Holdings Inc. (Nasdaq: ORGO), a leading regenerative medicine company focused on the development, manufacture, and commercialization of product solutions for the Advanced Wound Care and Surgical and Sports Medicine markets, today announced that its Phase 3 randomized control trial evaluating the safety and efficacy of ReNu, a cryopreserved amniotic suspension allograft (ASA), for the management of symptoms associated with knee osteoarthritis (OA) achieved its primary endpoint upon the analysis of positive top line data.

The study demonstrated a statistically significant reduction in knee OA pain at six months as assessed by the Western Ontario and McMaster Universities Arthritis Index pain scale compared with subjects treated with saline control. ReNu showed a favorable safety profile consistent with prior studies.

“These top line results are a milestone achievement for Organogenesis,” said Gary S. Gillheeney, Sr., President and Chief Executive Officer of Organogenesis. “We look forward to sharing this compelling new evidence in our ongoing discussions with the FDA as we believe ReNu can provide clinically meaningful benefits where few non-surgical options exist. If approved, introducing Renu as an innovative pain management solution for the millions of patients suffering from knee OA represents a significant new addressable market opportunity for Organogenesis.”

Knee OA is a degenerative joint disease that is estimated to affect nearly 31.1 million Americans and projected to grow to 34.4 million Americans by 2027. It is ranked among the most common causes of disability and poor quality of life, generally characterized by pain and functionality deficits. Up to 15 percent of knee OA patients are classified as severe (Kellgren-Lawrence [KL] grade 4). End stage management of the disease in these patients is typically a total knee replacement when all other treatment options are exhausted.

“To date, non-surgical treatment options for severe OA patients (KL 4) are limited—which represented approximately 30% of the enrolled patient population for this study,” said Adam B. Yanke, MD, PhD, Associate Professor of Orthopedics at Rush University Medical Center, a sports medicine and orthopedic surgeon and Co-Principal Investigator. “These topline results provide statistically significant evidence that the use of ReNu is a safe, effective treatment option for knee OA patients, if approved.”

A total of 515 patients with moderate to severe symptomatic knee OA (KL severity grade 2 to grade 4) were randomized to receive a single intra-articular injection of either ReNu or saline control balanced across groups. Patients were randomized to receive ReNu (ASA) 2 mL diluted with 2 mL of saline or 4 mL saline control. Statistically significant reductions in assessed knee pain (p=0.0177) were detected in the ReNu arm compared to the saline control arm six months after injection, and similar rates of adverse events were observed through 12 months of follow up. In addition to improving knee OA pain symptoms, ReNu maintained patient function compared to saline control (p < 0.0001).

“ReNu is supported by a robust and growing volume of scientific evidence,” said Patrick Bilbo, Chief Operating Officer of Organogenesis. “Based on the positive results of this pivotal trial along with our accumulated safety and efficacy data, we now plan to request a meeting with the FDA to discuss the clinical data requirements for a Biologics License Application filing. We look forward to having an update to share later this year and to initiating further studies to expand the potential clinical indications of ReNu.”

Complete analysis of the Phase 3 prospective, double-blind, multicenter, saline-controlled, parallel group clinical trial is expected in May. A second multi-center clinical trial for ReNu is actively enrolling with full enrollment expected this year, ahead of earlier expectations.
