Follow-up evaluation of cognitive function in the randomized Alzheimer's Disease Anti-inflammatory Prevention Trial and its Follow-up Study.

ABSTRACT: The Alzheimer's Disease Anti-Inflammatory Prevention Trial (ADAPT) and Follow-up Study (ADAPT-FS) examined effects of naproxen and celecoxib on cognition in the elderly. We report here results describing trajectories of cognitive evaluation test scores.A total of 2356 participants completed baseline and at least one follow-up cognitive evaluation between 2001 and 2004. Study treatments were discontinued in 2004, but participants were followed until 2007. A total of 1537 participants were reevaluated in 2010 to 2011. Outcomes include seven cognitive evaluations administered yearly in person in ADAPT and three of these evaluations that were administered by telephone near the end of ADAPT and again in ADAPT-FS.There were no important differences over time by treatment group on any ADAPT cognitive measure, a global composite, or the three cognitive measures reassessed in ADAPT-FS by telephone.Treatment for 1 to 3 years with naproxen or celecoxib did not protect against cognitive decline in older adults with a family history of AD.

Project description:ObjectivesThe Alzheimer's Disease Anti-inflammatory Prevention Trial (ADAPT) was designed to evaluate the conventional NSAID naproxen sodium and the selective COX-2 inhibitor celecoxib for primary prevention of Alzheimer's dementia (AD). On 17 December 2004, after the Adenoma Prevention with Celecoxib (APC) trial reported increased cardiovascular risks with celecoxib, the ADAPT Steering Committee suspended treatment and enrollment. This paper reports on cardiovascular and cerebrovascular events in ADAPT.DesignADAPT is a randomized, placebo-controlled, parallel chemoprevention trial with 1-46 mo of follow-up.SettingThe trial was conducted at six field sites in the United States: Baltimore, Maryland; Boston, Massachusetts; Rochester, New York; Seattle, Washington; Sun City, Arizona; and Tampa, Florida.ParticipantsThe 2,528 participants were aged 70 y and older with a family history of AD.InterventionsStudy treatments were celecoxib (200 mg b.i.d.), naproxen sodium (220 mg b.i.d.), and placebo.Outcome measuresOutcome measures were deaths, along with nonfatal myocardial infarction (MI), stroke, congestive heart failure (CHF), transient ischemic attack (TIA), and antihypertensive treatment recorded from structured interviews at scheduled intervals. Cox proportional hazards regression was used to analyze these events individually and in several composites.ResultsCounts (with 3-y incidence) of participants who experienced cardiovascular or cerebrovascular death, MI, stroke, CHF, or TIA in the celecoxib-, naproxen-, and placebo-treated groups were 28/717 (5.54%), 40/713 (8.25%), and 37/1070 (5.68%), respectively. This yielded a hazard ratio (95% confidence interval [CI]) for celecoxib of 1.10 (0.67-1.79) and for naproxen of 1.63 (1.04-2.55). Antihypertensive treatment was initiated in 160/440 (47.43%), 147/427 (45.00%), and 164/644 (34.08%). This yielded hazard ratios (CIs) of 1.56 for celecoxib (1.26-1.94) and 1.40 for naproxen (1.12-1.75).ConclusionsFor celecoxib, ADAPT data do not show the same level of risk as those of the APC trial. The data for naproxen, although not definitive, are suggestive of increased cardiovascular and cerebrovascular risk.
