Brief Summary
This research study will evaluate inter-individual variability in the response to the non-steroidal anti-inflammatory drugs (NSAIDs), celecoxib and naproxen, among healthy adults. It will also investigate what factors, like age, sex, or genetic background, cause this variability.

Outcome Measures
Primary Outcomes (4)
COX-1 Activity ex Vivo
COX-1 activity was measured ex vivo using a whole blood assay. Thromboxane A2 serum concentrations were quantified before, and 0.5, 1, 2, 4, 8, and 12 h after treatment and expressed as AUC over the 12 hour dosing interval.
12 hours
COX-2 Activity ex Vivo
COX-2 activity was assessed ex vivo using a whole blood assay. Prostaglandin E2 concentrations in LPS-treated plasma were quantified before, and 0.5, 1, 2, 4, 8, and 12 h after treatment and expressed as AUC over the 12 hour dosing interval.
12 hours
COX-1 Activity in Vivo
COX-1 activity was measured in vivo by quantifying the urinary metabolite of thromboxane A2 before, and 1, 2, 4, 8, and 12 h after treatment, normalized to urinary creatinine and expressed as AUC over the 12 hour dosing interval.
12 hours
COX-2 Activity in Vivo
COX-2 activity was measured in vivo by quantifying the urinary metabolite of prostaglandin I2 before, and 1, 2, 4, 8, and 12 h after treatment, normalized to urinary creatinine and expressed as AUC over the 12 hour dosing interval.

Study Arms (2)
High Dose
EXPERIMENTALDuring each treatment phase, subjects will receive celecoxib (200 mg by mouth twice daily), naproxen (500 mg by mouth twice daily), or placebo (twice daily) for 7 days. Subjects will be instructed to take the study medications twice a day (at approximately 8 AM and 8 PM) on an empty stomach with a full glass of water.
Low dose
EXPERIMENTALDuring each treatment phase, subjects will receive celecoxib (100 mg by mouth twice daily), naproxen (250 mg by mouth twice daily), or placebo (twice daily) for 7 days. Subjects will be instructed to take the study medications twice a day (at approximately 8 AM and 8 PM) on an empty stomach with a full glass of water.
Interventions
Eligibility Criteria
You may qualify if:
- Adult men and women greater than 18 years of age who are non-smokers and in good health based on medical history, physical examination, vital signs, and laboratory tests. Volunteers with adequately controlled hypertension and hyperlipidemia (total cholesterol of ≤270 mg/dL) may participate in the study.
You may not qualify if:
- Female subjects who are pregnant or nursing a child.
- Subjects who have received an investigational drug or used an experimental medical device within 30 days prior to screening, or who gave a blood donation of ≥ one pint within 8 weeks prior to screening.
- Subjects with any coagulation, bleeding or blood disorders.
- Subjects who are sensitive or allergic to celecoxib (Celebrex) or naproxen (Naprosyn) or their components.
- Subjects who are sensitive or allergic to aspirin or other NSAIDs.
- Subjects with documented history of any gastrointestinal disorders, including bleeding ulcers.
- History of significant cardiovascular disease (including stroke or TIA), renal, hepatic, respiratory (except infections which longer \> 6 months prior to screening), immune, endocrine, hematopoietic disorder or neurological disorders.
- History of cancer within the last 5 years (except for cutaneous basal cell or squamous cell cancer resolved by excision, or carcinoma in situ of the cervix adequately treated).
- Has taken NSAIDs or anti-secretory agents (proton pump inhibitors or H2 receptor antagonists) within 14 days prior to study drug administration
- Has ever taken the any anti-platelet or anti-coagulant agents
- Used dietary or herbal supplements containing salicylates, Vitamin E, fish oil, or any other herbal supplements, within 14 days of study drug administration.
- Subjects with any abnormal laboratory value or physical finding that according to the investigator may interfere with interpretation of the study results, be indicative of an underlying disease state, or compromise the safety of a potential subject.
- Subjects who have had a history of drug or alcohol abuse within the last 6 months.
- Subjects who are unwilling to provide a blood sample for genetic analyses and creation of a lymphoblastoid cell line.
