Official title
A Single Center, Double-blind, Placebo-controlled Phase I Single-dose Cross-over Study in Healthy Subjects to Investigate the Inhibitory Effect of CG100649, Celecoxib, Naproxen, and Acetazolamide on the Activity of Cyclooxygenases (COX-1, COX-2) and Carbonic Anhydrases (CA-I, CA-II)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
