Effects of Dual Cyclooxygenase-2 and Carbonic Anhydrase Inhibition
Summary
Cyclooxygenase-2 (COX-2) inhibitors have become a common analgesic treatment option for patients with arthritis. However, long-term treatment has been associated with increased cardiovascular risk. With the past withdrawals and rejections of approval for COX-2 inhibitors the treatment options are now very limited. This translates for example to about 10 million osteoarthritis patients in the US who cannot receive COX-2 inhibitors because of concomitant hypertension. And this exemplifies the unmet medical need to develop and offer safe treatment options for this particular patient population. This trial investigates pharmacodynamic aspects of CG100649 which is being developed as a novel COX-2 inhibitor. Preclinical data show a dual mechanism of action, which consists of the inhibition of the two enzymes COX-2 and carbonic anhydrase-I/-II (CA-I/II) and through which the cardiovascular risk of COX-2 inhibition might be attenuated.
