The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
Information provided by (Responsible Party):
Oxford Pharmascience Ltd
The Sponsor is developing a new form of naproxen (the study drug, OXP005), for the potential treatment of rheumatic and painful conditions. The study will compare the study drug to an already marketed formulation of prescription strength naproxen (Naprosyn® the reference product) by looking at how a single dose of the drug is taken up by the body. The safety and tolerability of the drug will also be assessed.
