Enekinragene inzadenovec

-- Poster to be presented at ACR Convergence annual meeting --PARSIPPANY, N.J., Nov. 14, 2024 (GLOBE NEWSWIRE) -- Pacira BioSciences, Inc. (NASDAQ: PCRX), the industry leader in the delivery of innovative, non-opioid pain therapies to transform the lives of patients, today announced new data demonstrating its gene therapy for osteoarthritis candidate, PCRX-201 (enekinragene inzadenovec), provided sustained improvements in knee pain, stiffness, and function to 104 weeks following local administration, with a well-tolerated safety profile. The data, which indicate a potential for sustained clinical efficacy in patients with moderate to severe osteoarthritis of the knee (OAK), will be presented during a poster session at the American College of Rheumatology’s annual ACR Convergence meeting on Sunday, November 17 from 10:30 am – 12:30 pm EST. “The results of this large phase 1 study demonstrate durable pain relief across all levels of disease severity for at least 2 years following a single injection. This is promising, considering traditional pain management interventions provide an average of three to six months of effect,” said Stanley Cohen, MD, a board-certified rheumatologist and Co-Medical Director of the Metroplex Clinical Research Center in Dallas, TX, who was lead investigator in this trial and primary author on the poster presentation. “Unlike other treatments that temporarily alleviate symptoms, PCRX-201 addresses a root cause of osteoarthritis knee pain—inflammation—to help control patients’ pain for years rather than months.” The new data is derived from an open-label, phase 1 trial investigating the safety and efficacy of PCRX-201 administered via ultrasound-guided intraarticular injection in 72 patients with OAK graded at 2, 3, or 4 on the Kellgren-Lawrence scale, a semiquantitative method for evaluating the severity of osteoarthritis on a scale of 0-4. Participants were broken into two cohorts. The first cohort received one of three doses of PCRX-201. The second cohort received concurrent pretreatment with an intraarticular corticosteroid (methylprednisolone 40 mg), a technique common in gene therapy dosing to improve tolerability and gene transfer. Pain and function benefits were observed at all doses and across both cohorts over the full 104 weeks studied, with patients in the second cohort achieving greater pain reduction and fewer adverse events (AEs). Additional results in the pretreated cohort, across all doses, include: 48%-65% improvement in pain from baseline, as measured by the Western Ontario and McMaster Universities Arthritis Index-A (WOMAC-A)53%-72% improvement in stiffness from baseline, as measured by WOMAC-B Improvements in function from baseline, as measured by the Knee Injury and Osteoarthritis Outcome Score (KOOS) Activities of Daily Living (ADL) scale, that were similar to improvements in WOMAC-A and WOMAC-B By 16 weeks more than 70% of participants achieved greater than 50% reductions from baseline pain. No serious treatment-emergent AEs related to the treatment or procedure were reported regardless of steroid pretreatment or dose level administered. Treatment-related joint effusions (swelling) were the most common AE, occurring in 36% of patients who received steroid pretreatment vs 61% of patients who were not pretreated. The majority of effusions were mild to moderate in severity and resolved in a median of 33 days among patients in the pretreated group. “We look forward to continuing to advance the clinical investigation of PCRX-201 following these promising results, with a Phase 2, double-blind, active-controlled study planned for 2025,” said Frank D. Lee, chief executive officer of Pacira BioSciences. “Unlike traditional gene therapies, which are administered systemically and have primarily been limited to the treatment of rare diseases, we believe PCRX-201 holds the broad potential to provide a long-term pain management solution for the 14 million U.S. patients suffering from the negative impacts of osteoarthritis of the knee. With a local administration that delivers relief directly to the source—the knee joint capsule—PCRX-201 is on the leading edge of what could be possible for gene therapies and offers patients the hope for a long-lasting pain management solution that improves their ability to comfortably engage in activities of daily living, like climbing stairs and exercising.” PCRX-201 is a locally administered gene therapy, designed to produce interleukin-1 receptor antagonist (IL-1Ra), a naturally occurring, anti-inflammatory protein with a proven mechanism of action that reduces interleukin-1 (IL-1) signaling, a known factor in the development and progression of osteoarthritis of the knee. Unlike systemically administered gene therapies, PCRX-201 delivers the medicine where it matters to reduce pain and disability and potentially slow structural progression at the site of the disease. PCRX-201 uses an inducible promoter to mimic the body’s natural response to inflammation by “turning on” the expression of IL-1Ra when inflammation is present in the joint and turning off IL-1Ra expression once inflammation is quelled. In March 2024, PCRX-201 became the first-ever gene therapy product candidate in osteoarthritis to receive Regenerative Medicine Advanced Therapy (RMAT) designation from the U.S. Food and Drug Administration (FDA). RMAT designation provides the benefits of intensive FDA guidance on efficient drug development, including the ability for early interactions with the FDA to discuss surrogate or intermediate endpoints, potential ways to support accelerated approval and satisfy post-approval requirements, potential priority review of the Biologics License Application (BLA), and other opportunities to expedite development and review. PCRX-201 was also granted Advanced Therapy Medicinal Products (ATMP) designation by the European Medicines Agency in May 2023. About Pacira BioSciencesPacira BioSciences delivers innovative, non-opioid pain therapies to transform the lives of patients. Pacira has three commercial-stage non-opioid treatments: EXPAREL® (bupivacaine liposome injectable suspension), a long-acting local analgesic currently approved for infiltration, fascial plane block, interscalene brachial plexus nerve block in adults, sciatic nerve block in the popliteal fossa in adults, and adductor canal block in adults for postsurgical pain management; ZILRETTA® (triamcinolone acetonide extended-release injectable suspension), an extended-release, intra-articular injection indicated for the management of osteoarthritis knee pain; and ioveraº®, a novel, handheld device for delivering immediate, long-acting, drug-free pain control using precise, controlled doses of cold temperature to a targeted nerve. The company is also advancing the development of PCRX-201, a novel locally administered gene therapy with the potential to treat large prevalent diseases like osteoarthritis.
