Bristol-Myers Squibb Company (NYSE:BMY) announced today the U.S. Food and Drug Administration (FDA) has approved ORENCIA for the treatment of adults with active Psoriatic Arthritis (PsA), a chronic, inflammatory disease that can affect both the skin and musculoskeletal system. ORENCIA is approved and available in both intravenous and subcutaneous (SC) injection formulations. ORENCIA should not be administered concomitantly with TNF antagonists, and is not recommended for use concomitantly with other biologic Rheumatoid Arthritis (RA) therapy, such as anakinra. This approval marks the third autoimmune disease indication for ORENCIA.
“This approval underscores the efficacy of ORENCIA in adult patients with active Psoriatic Arthritis, who have been in need of new treatments,” said Brian J. Gavin, Vice President, ORENCIA Development Lead at Bristol-Myers Squibb. “Helping to advance clinical understanding of autoimmune conditions is a key focus of our immunoscience research, and we’re proud to introduce ORENCIA, a selective T-cell co-stimulation modulator, as an additional treatment option for PsA.”
The co-stimulation blockade of ORENCIA inhibits T-cell activation and the resulting cascade of events that contribute to inflammation. T-cell activation is involved in the pathogenesis of PsA.
Psoriatic Arthritis can cause joint pain, stiffness and reduced range of motion, potentially affecting the ability to do everyday activities, such as getting dressed and tying shoes. In PsA, the immune system attacks healthy joints and skin.
“Psoriatic Arthritis takes a toll on patients and families over time,7” said Randy Beranek, president and CEO, National Psoriasis Foundation. “We welcome the introduction of an additional treatment option for adults with active Psoriatic Arthritis, because we believe advancements, along with further research, education and support services, are critical to helping improve the lives of those impacted.”
The approval was based on results from two randomized, double-blind, placebo-controlled trials in which ORENCIA improved (or reduced) disease activity in both TNF-naive and exposed patients with high disease activity, high tender and swollen joints, and a disease duration of more than seven years.
ORENCIA PsA IV and SC Studies Demonstrated Improved Disease Response
The efficacy of ORENCIA was assessed in two randomized, double-blind, placebo-controlled studies (Studies PsA-I and PsA-II) in 594 adult patients with disease duration more than seven years. Patients had active Psoriatic Arthritis (≥ swollen joints and ≥ tender joints) despite prior treatment with DMARD therapy and had one qualifying psoriatic skin lesion of at least 2 cm in diameter. In PsA-I and PsA-II, 37% and 61% of patients, respectively, were treated with TNF inhibitors (TNFi) previously. The primary endpoint for both PsA-I and PsA-II was the proportion of patients achieving ACR 20 response at Week 24 (Day 169).
In PsA-I, a dose-ranging study, 170 patients received study drug IV at Days 1, 15, 29, and then every 28 days thereafter in a double-blind manner for 24 weeks, followed by open-label ORENCIA every 28 days. Patients were randomized to receive placebo or ORENCIA 3 mg/kg, 10 mg/kg (weight range-based dosing: 500 mg for patients weighing less than 60 kg, 750 mg for patients weighing 60 to 100 kg, and 1000 mg for patients weighing greater than 100 kg), or two doses of 30 mg/kg followed by weight range-based dosing of 10 mg/kg without escape for 24 weeks. Patients were allowed to receive stable doses of concomitant methotrexate, low dose corticosteroids (equivalent to ≤ 10 mg of prednisone) and/or NSAIDs during the trial. At enrollment, approximately 60% of patients were receiving methotrexate.
