New clinical trial aiming for comprehensive insights into an efficient treatment for Osteoarthritis

Wobenzym and Artialis are pleased to announce that they have randomized the first Osteoarthritis patients for the Wobe-SMART clinical study.


Nestlé Health Science and Artialis (Belgium), a research organization specialized in the field of musculoskeletal disorders, have jointly developed a post-marketing clinical trial to address patients suffering from Osteoarthritis (OA) of the knee. The Wobe-SMART trial, to be conducted in Belgium, will further elucidate the mechanism of action of Wobenzym® by using state of the art technologies in proteomics and cartilage biomarkers research to reveal pathways and targets modulated by Wobenzym®. This study is also unique in with additional innovative clinical parameters such as the structural evaluation of joint tissues by magnetic resonance imaging (MRI) and the physical mobility of patients using connected devices.


Osteoarthritis (OA) affects more than 250 million of people worldwide1. OA of the knee is a painful condition and one of the most common causes of physical disability among older adults. It’s estimated that globally 9.6% of men and 18.0% of women aged over 60 years have symptomatic osteoarthritis and are hence affected by the burden of this disease2.


There are few treatment options that can help to relieve pain and improve mobility, especially for a safe long-term use, therefore there is a high unmet need for an anti-inflammatory treatment that is effective in reducing symptoms, but is also well tolerated and has a superior risk-benefit profile.


Wobenzym® is an oral enzyme combination with Bromelain, Trypsin and includes the flavonoid rutoside. It is approved as a pharmaceutical drug in Germany and many other countries in the EU and CIS/CEE region, supported by clinical evidence. A 2016 published meta-analysis has confirmed that Wobenzym® is as effective as gold standard NSAID Diclofenac in reducing joint pain, increasing joint function and mobility and yet has a favorable safety profile bringing a clear clinical benefit to patients with knee osteoarthritis3. While it is well established that Wobenzym® is safe and has proven efficacy in painful conditions, inflammation and OA, this clinical study is going to provide further insights on its mechanism of action.
