Osteoarthritis causes and symptoms
Otezla (apremilast) is an inflammatory drug indicated for the treatment of adult patients with active psoriatic arthritis (PsA).
Osteoarthritis is a disease of joints of the knee, which is caused by aging joints, injury and obesity. The disease occurs due to the breakdown of cartilage, which is part of the joint that cushions the knee bone ends. The symptoms of the disease include pain in the affected joints, and stiffness. The disease commonly affects middle aged and older people.
More than five percent of the people in the world are estimated to be affected by osteoarthritis of the knee. The disease also affects about 10 million people in the US.
Monovisc’s mechanism of action
Monovisc contains sterile, non-pyrogenic, viscoelastic solution of sodium hyaluronan (NaHA). The drug is made from bacterial cells and includes combination of a proprietary cross-linker. The drug replaces natural hyaluronic acid in the body and provides significant pain relief from the symptoms of OA.
The drug is available in a disposable glass syringe of 4.0ml dose that can be administered through intra-articular injection.
Clinical trials on Monovisc
FDA approval of Monovisc was based a pivotal phase III clinical trial. The randomised, controlled, double-blind and multi centre clinical study enrolled 369 patients with OA of the knee in 31 centres from the US and Canada. The objective of the study was to evaluate the safety and effectiveness of Monovisc for the treatment of joint pain.
Patients were randomised to receive either Monovisc or control (saline injection). They were evaluated for improvement in pain based on the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) after 26 weeks of the study.
The primary effectiveness analysis showed that the patients treated with Monovisc achieved a greater improvement from baseline in WOMAC pain score versus control after 12 weeks. The safety analysis of the study showed that Monovisc had an extremely low rate of adverse events. No serious adverse events were reported in Monovisc group during the clinical study.
