Description

Developed by the German pharmaceutical company, Merckle GmbH, together with EuroAlliance partners Alfa Wassermann and Lacer, licofelone (ML3000) is a dual COX/LOX inhibitor and the first member of this new class of analgesic and anti-inflammatory drugs. It is currently under evaluation as a treatment for osteoarthritis (OA), the most common form of arthritis. Although phase III trials have been successfully completed in OA patients no dates for regulatory submission have yet been given.

Pharmacology
IndicationFor the management of osteoarthritis.
PharmacodynamicsLicofelone belongs to a novel class of dual-acting anti-inflammatory drugs called COX/LO inhibitors. This group of drugs simultaneously inhibits the enzymes cyclooxygenase (COX) and 5-lipoxygenase (LO).
Mechanism of actionLicofelone, through combined 5-LOX/COX-inhibition, reduces levels of inflammatory prostaglandins and leukotrienes.
